It's virtually impossible to list tropes for these characters without spoiling everything or creating Self Fulfilling Spoilers because of the large amount of surprising reveals and murderer/victim exclusive tropes this game contains just like its predecessor.
A young man who has always admired Hope's Peak Academy and finally achieved his dream of attending the school. Unfortunately, he has forgotten his past and the Ultimate talent that he was selected for. Hinata is a decent guy, but his personality is rough around the edges and very skeptical.The truth is that he has no Ultimate talent, but his obsession with Hope's Peak led him to become the subject of the "Ultimate Hope Project", in which his identity would be completely erased and rebuilt as "Izuru Kamukura", the multi-talented "Ultimate Hope". Unfortunately, Kamukura fell under the thrall of Junko Enoshima and triggered "The Worst, Most Despair-Inducing Event In Human History" by his participation in the first "School Life of Mutual Killing", causing the death of the student concil. During the final trial he is faced with the dilemma of remaining as "Hajime Hinata" and letting AI Enoshima win, or reverting back to "Izuru Kamukura". He ultimately chooses the latter, accepting responsibility for his bloodied past and resolving to create a new future for himself and his classmates, but as a result is indicated to retain his old self.
Amateur Sleuth: As our protagonist he is certainly one of these, with some help from his fellow classmates.
Amnesiac Hero: Can't remember his Ultimate Level talent. Which is justified because it turns out he doesn't have one. As Hajime Hinata anyways. According to the final trial, the reason behind his lack of memories is because they were destroyed when he became Kamukura.
Ascended Fanboy: Was a huge fan of Hope's Peak and was ecstatic to become a student there. Though not for the reason he wanted.
Back from the Dead/Not Quite Dead: Hinata’s personality was completely suppressed to make way for Kamukura. Thanks to Naegi and the New World Program, it’s the only reason Hinata ever resurfaced.
Battle Aura: After overcoming Izuru's despair, like when Ishimaru became Ishida in the previous game.
Be Careful What You Wish For: He wanted to get a talent and be recognized as someone special so badly, well, he did…sadly, it all went straight to hell.
Because You Were Nice to Me: On both sides of this. For Hinata, it’s the reason why he’s hesitant to believe Komaeda could betray him. As for Tsumiki and Komaeda, it’s because of his persistent kindness, and trying to understand them that they grow strong feelings for him.
Big Bad Friend: Technically yes, not only is Hinata, as Izuru Kamukura, responsible for nearly everything wrong happening in the game. To make matters worse, because of his actions of wanting to have a talent, he indirectly helped Junko Enoshima bring the world to its end. And before that, besides Junko, he was the other main reason for all the chaos happening in Hope's Peak, the school he adored. To top it all off, as IzuruKamukura, he killed most of the student council, and because he smuggled AI Junko, most of the friends he made are now in comas.
Break the Cutie: All of the deaths, trials, executions, his missing memories, figuring his out his talent or lack of thereof, and Komaeda's sanity slowly slipping away, were already pushing him to the limit bit by bit. Chapter Six and the final trial is what really causes him to call it quits on everything. The result? He's got a Broken Smile, Laughing Mad at the Sadistic Choice, and Dull Eyes of Unhappiness. Poor guy doesn't get a break until Nanami shows up and helps him to snap out of it and get better.
Break Them by Talking: AI!Enoshima does this to him by dropping bombshell, after bombshell about who he is and the results of his actions. Not to mention his very existence was at risk of being erased forever and reverting back to Kamukura. Luckily he snaps out of it, and even hands it back to her by telling her that they're nothing like her because of the faith and strength to at least try moving on with their lives.
Cannot Spit It Out: It isn't until his very last moments in the game before returning to the real world that Hinata finally brings himself to thank Nanami for everything she's done for him.
The Caretaker: Played for Laughs in Nanami's spin-off manga, Hinata gets assigned to briefly take care of Komaeda when he gets the despair fever. He has to carry Komaeda twice and even cook him a meal. He can even be seen wearing an apron and kitchen gloves bringing a very happy Komaeda his meal. On a serious note, if Komaeda does survive and wakes up from his coma, this might be foreshadowing.
"That's wrong!" when he points out a contradiction in court, just like Naegi in the original game.
To a lesser extent, "I agree with that!" when he agrees with someone else's statement in court.
There's also "I'll cut that claim to pieces!" when he wins a Rebuttal Showdown.
Classic Anti Hero: Past!Hinata was this. By the time Chapter 4 through 6 comes around, he begins to shift back into this. Luckily, after coming to terms with everything, he gets better.
Contrasting Sequel Main Character: Compared to Naegi, Hinata is noticeably more cynical. While Naegi was non-confrontational, polite (some might say overly so), and docile, Hinata is not afraid to say what's on his mind, to the point where he sometimes forgets to watch his mouth, and willing to take sides in an argument. Despite not remembering his talent, he treats the other students more like his equals, while at the same time trusting them far less. When Monokuma reveals his game, Hinata almost immediately accepts the idea that anyone around him might be willing to kill to escape. It actually gets much stronger that, namely that while Naegi had a complex over his talent not being as special, he still didn't let it get to his head and ultimately gained a new talent in the end. Hinata turns out to be so insecure about his lack of talent he willingly erased his whole identity just so he could be special.
Covert Pervert: Played for Laughs. In order to see certain FanserviceyEaster Eggs, you need certain items in your inventory. Leading up to these scenes, Hinata can start acting very strangely. In the most blatant instance where he chooses to spy on two of the girls bathing together, he comments afterwards about how he doesn't know what got into him. In the second most blatant example, he delivers a Rousing Speech to convince Souda to spy on two of the others whom they suspect are doing THAT.
Dead All Along: Zig-Zagged. While Hinata technically still exists, it turns out the Hinata we've being playing as was simply what could be pieced together from his original personality prior to surgery.
Death of Personality: He willingly underwent this before the game begins, being so desperate to have a talent and become special that he had his original personality completely suppressed in order to become Izuru Kamukura. The trope is played with a bit since Hinata technically still exists in this game, but the Hinata we've come to know is only what was pieced together from his original personality.
Et Tu, Brute?: Doesn’t take Komaeda’s betrayal well at all. He doesn't take Tsumiki's Face-Heel Turn well either, if anything, he begs her to just come clean about it during the trial so that he could still believe in her.
Even the Guys Want Him: It's mentioned in Hinata's character profile in the official artbook that he spends his time talking with everyone about one thing or another, and gets along great with both the girls and the guys of the cast. In Dangan Island, some of the possible events and endings have romantic undertones, which certain characters even comment on.
Evil Costume Switch: As Kamukura, he wears a completely black suit and tie, with only a white dress shirt.
Evil Make Over: At some point the process that turned him into Kamukura made his normally green eyes turn red and his hair darken to black, which counted as this when he then fell into Despair.
Freak Out: Doesn't take learning his true identity well.
The Heart: Becomes this at the end of trial Six to help snap his friends out of their Heroic BSOD, and convince them to do the force shutdown. Indirectly, he shows shades of becoming this to the entire cast if one were to take in his interactions with them such as free time events or Dangan Island.
Heroic BSOD: Upon finding out that he not only caused his classmates' deaths as well as being the reason that The Worst Most Despair-inducing Incident in the History of Mankind started as Izuru Kamukura, the man who was meant to represent the fruits of Hope's Peak Academy's research into talents and "hope", but also that if he pulls the plug on the program as Naegi intends, he will come back as "Izuru Kamukura" instead of "Hajime Hinata".
Hurting Hero: Spends an entire day in bed after the trial of Komaeda and Nanami’s deaths, he states that he could only pray and hope nothing else bad happens to the others, hinting that even he is reaching his limits.
I Just Want to Be Special: Deconstructed. He wanted to feel special and be a part of Hope's Peak Academy no matter what, even if it meant that he'd only be a reserve course student... And he was willing to go as far as to risk losing his original identity to achieve this...
I Will Wait for You: He and the other survivors made a vow to wait until all of their comatose friends awaken.
Kid with the Leash: Besides trying to understand Komaeda after the events of trial one, Hinata has his moments where he'll try to restrain Komaeda whether it'd be from Hope speeches, or after Komaeda begins to antagonize them. Sometimes it works, but after Chapter Four, he's completely lost his grip on the leash. Bless his heart for trying, but not even being possibly Komaeda's Morality Pet will change or even stop Komaeda anymore. On a lighter note, in Nanami's spin-off manga, this is Played for Laughs when Komaeda catches the despair fever. Hinata is literally chasing Komaeda down to get him to stop causing chaos.
Laughing Mad: Has a small one when taking in all of the bombshells Junko has dropped on him.
The Lost Lenore: Nanami might become his, as he really took her death hard. The fact that he didn't get a chance to thank her until the very end of Chapter Six doesn't help him to cope with her death. Before he returns to the real world, he makes several references that he'll never forget about her. This was one of the reasons why he was a bit hesitant on doing the force shut-down, as there was a chance he and the other survivors would forget about her existence entirely.
Love Martyr: Towards Hope's Peak Academy, and they took advantage of it, thus starting the events of everything in the series.
Meaningful Name: A very subtle one. Hajime means 'Beginning' or 'First' but the characters used to write it mean 'To cut'. Hence, Kamukura began with a cut to the head and Hinata is the first protagonist in a Danganronpa game to employ the "Cut arguments to pieces" mini-game in the trials, the beginning of a new gameplay mechanic.
Morality Pet: A complicated version of this with, but Hinata could be considered Komeada's. Even after Komaeda finds out that Hinata doesn't have a talent and is part of SHSL Despair, he admits to Hinata that he holds a soft spot for him. In his final video message, he states that he should hold back on being too harsh on Hinata. Considering the events of Absolute Despair Girls, Hinata is still the only person who Komaeda genuinely, and honestly holds any real care for. Ironically, had Komaeda not betrayed Hinata, this could have been the other way around as Komaeda was the one who was doing his best to calm Hinata down and get him to loosen up in Chapter 1. However, Kamukura slammedthe door to Komaeda's attempt at forming a friendship.
Nice Guy/Jerk with a Heart of Gold: Is a very good mix of this, though more often than not, he's actually nice. Though he does tend to speak his mind out even if his statements come across as a bit rude, and will also snark at his classmates. He's even forgiving to the ones who were the culprits. Towards the end of Chapter 4, he's even nicer than Komaeda, though that's more because of Komaeda's sudden shift in personality.
Only Sane Man: Is very aware that practically everyone around him are special in ways beyond just their talents.
One-Winged Angel: After gaining the strength to continue, his hair turns white as he gains the power to shoot down any argument.
OOC Is Serious Business: When he's forced to accuse Nanami of being Komaeda's "murderer" and the traitor in order to save everyone else, you can hear his voice shaking when he makes his typical lines for fingering the suspect, and you can see him with many distressed facial expressions.
Hinata: ...Wait, huh? Was my... characterization always this way?
Properly Paranoid: Of all the students, Hinata is the only one to suspect that something's off about Usami's class trip. Sure enough, his suspicions are confirmed when Monokuma returns...but this turns out to be subverted in that Usami has nothing to do with Monokuma. His return was made possible by Hinata himself, and if the class trip had gone as Usami had planned, everyone would have left together as she said they would as seen in the alternate universe Dangan Island. Though in his defense, he technically didn't have much control over what Izuru Kamukura did.
Red Eyes, Take Warning: Played straight in his past but later subverted when he comes to terms with the choice he must make in building a new future for himself.
Red Oni, Blue Oni: The red to Nanami and Komaeda's blue, and the blue to Souda's red.
Ridiculously Average Guy: Part of Hinata's difficulty with figuring out his talent is how normal he appears to be. Mostly because he doesn't have a talent.
Sole Survivor: Of the Hope's Peak Academy's Reserve Course students: everyone but him committed group suicide.
Straight Man: Somewhat. He's usually the one musing about others' bizarre personality quirks.
Tomato in the Mirror: Besides being part of Ultimate Despair group, they take it a step farther by revealing that he has been the main subject of a series of experiments where his personality was repressed completely in order to produce the "Ultimate Hope": Izuru Kamukura. Izuru Kamukura promptly fell to despair when Junko forced him to participate in the very first mutual killing, leading to him killing most of the student council of Hope's Peak Academy as detailed in Dangan Ronpa Zero. This was covered up, then leaked by Enoshima, starting the Worst Most Despair-inducing Incident in the History of Mankind. Izuru Kamukura was also the one who brought the Enoshima AI in which allowed Monokuma/Junko to repeat the mutual killings that happened in Hope's Peak Academy.
Tall, Dark and Snarky: Well, not that dark, but certainly snarky enough to qualify. Kamukura brings him closer to the "Dark" requirement.
Unwitting Instigator of Doom: His decision to become Kamukura is what allowed Enoshima to cause the Worst Most Despair-inducing Incident in the History of Mankind. In short, Hinata's actions caused the plot of the entire franchise.
An utterly unremarkable Ordinary High-School Student who was only selected to attend Hope's Peak Academy through a random lottery, giving him the title of "Ultimate Lucky Student". He's an affable and easygoing guy, though he tends to be quite self-effacing towards his own "talent", claiming that it's not a real talent at all (at least compared to the other students). It turns out he really is that lucky, and uses his abnormally good luck to his advantage several times. He plots a murder in Chapter 1 (which is foiled) and later becomes the victim of Chapter 5 after he masterminds his own "murder" with the intent of killing everyone except for the mole, as he had discovered the truth about their relation to Ultimate Despair.
Alas, Poor Villain: Despite his crazy, creepy behaviour eventually descending into what looks like full-blown insanity, everyone is horrified by the torturous nature of his death, although the horror gives way to anger once they realize what he was planning.
All-Loving Hero: He claims to love all of his classmates and believes that they can conquer any level of despair. Can be seen as an exaggeration of Naegi's role in the first game. Turns out to be a dark version of this trope, in that he expresses said love and confidence by jump-starting the mutual killing, aiding the first culprit, and generally creeping everyone out. He sheds this behavior near the end of the game, after finding out that the classmates he trusted so much were members of Ultimate Despair (along with Komaeda himself).
All There in the Manual: Most of Komaeda's character motivation and lot of things that were simply hinted at in the game are shown in much greater depth in his manga, which shows the events of the story from his perspective.
Ambiguous Disorder: Subverted. He seems to not realize when his lack of tact is hurting someone, makes rather extreme reactions to things in Dangan Island that are remotely dangerous, and his feelings in regards to hope are rather... obsessive. However, in his final free time event, he mentions suffering from frontotemporal dementia (a condition his behavior matches up with), and although the game leaves it open to interpretation whether or not he was lying, side materials confirm his claims.
Born Lucky/Born Unlucky: Like Naegi before him, Komaeda got in via winning a lottery, which gives the talent as a default, hence why he considers it far more lackluster in comparison to the others. In reality, he is that lucky and it's deconstructed rather horribly. While his cycle of luck did allow him to win several lotteries and get into the Academy, it came at some rather severe costs (such as the deaths of his parents and being diagnosed with a terminal illness) and has made him a nigh unstable Death Seeker.
Bound and Gagged: In Chapter 2, following his behaviour in the previous chapter minus the "gagged" part, and again in Chapter 5 in his death scene. Interestingly enough, one of the few gifts he dislikes is a gag ball, possibly due to being kidnapped as a child.
Break Them by Talking: Disturbingly good at reading others and getting into their heads, as he proves in Chapter 2. When called on this, however, he insists 'trash like him' couldn't possibly influence others.
Can't Kill You, Still Need You: Saionji suggests that his offer to any would-be killers to go to him for help is based on this trope, so that anyone who wants to kill him would see value in keeping him alive. It turns out that Komaeda is willing to sacrifice his own life if need be.
Cynicism Catalyst: The nature of his luck—or how he perceives it working—has provided plenty of these, such as witnessing the deaths of his parents or being diagnosed with a terminal disease. However, somewhat zig-zagged that on top of making him a pessimist, it also led to his obsessive belief in hope.
Dark and Troubled Past: Let's just say the "unlucky" aspect of his talent has made his life very hard on him, though how much of what he tells us about it is true is left ambiguous in the game. Side materials have either confirmed or heavily hinted at most of what he mentions, however.
Death Seeker: As revealed in his Dangan Island ending, he wanted to die on the island, seeking release from the cycle of good luck and bad luck that follows him at every step of his life. In the main story, he fulfills this trope by seeking a death that will bring hope to the other students.
Despair Event Horizon: Like everyone else, he was a member of Ultimate Despair, so he had to have crossed it at one point. However, he also arguably crosses it again upon learning that he and all of the Ultimates he's been admiring as "Hopes" were actually "Despairs".
Detective Mole: In Chapter 1, Komaeda is eager to help Hinata with the investigation, but it soon becomes apparent that he's hiding something. He also seems oddly insistent that none of the students could have committed the crime. Ultimately played with; he isn't the culprit of the case, but he was covering for the real culprit during the trial, and is also the one who engineered the whole thing.
Deuteragonist: Along with being the first person you meet and serving as a rival to Hinata, he acts as a sounding board to the investigation and serving as Mr. Exposition. You even get to play as him for one point. Ultimately however, he actually switches to Tritagonist in terms of role, as he is rarely brought up in the final trial except in regards to his actions and Nanami fills the closer support role.
Devil's Advocate: He's more than willing to help the murderer try to get away with it, in order to truly challenge the others and see whose Hope is stronger.
Dies Wide Open: Notable for being the only example in the series (not counting the anime's version of Chihiro Fujisaki's death) since every other victim has their eyes shut or obscured in their death pose.
Disease Bleach: It's implied his illness is responsible for turning his hair white.
Early-Bird Cameo: He is mentioned indirectly as the 77th years Good Luck student in one of the sidestories for the first game. A person claiming to be SHSL Despair who appears to Ryouko in Dangan Ronpa Zero might be him as well, as they share an almost identical speech pattern.
Et Tu, Brute?: Finding out the people he looked up to are actually the Remnants of Despair, he begins to antagonize them.
Evil Cannot Comprehend Good: For most of the game, Komaeda cannot seem to understand that the reason the others hate him has nothing to do with how "useless" he believes his talent is or how "hopeless" their mindset has become, and everything to do with the fact that he's a suicidal, homicidal wreck who constantly antagonizes them and endangers their lives. Even in death, he only manages to kill two innocent people who were actively working to help the other students, and comes this close to screwing them out of activating the reset in the endgame.
Evil Laugh: A very startling example. Not helped by the fact he really is mentally ill and shares the same voice as our previous protagonist.
Expy: He's seemingly an expy of Makoto Naegi from the previous game, right down to having the same voice actors in both Japanese and English. They also have a similar fashion sense, their talent is Ultimate Lucky Student, and they both have little confidence in their worth when compared to the other students. However, he also acts as Naegi's Evil Counterpart, as Komaeda's raging inferiority complex, flip-flopping "luck" and utter dedication to the ideal of "hope" renders him far more unstable than Naegi. Word of Godconfirms that his status as an Evil Counterpart is intentional.
Foreshadowing: Just before trial 4 even begins, Komaeda talks to Hinata about a mystery novel. This novel was about a schoolgirl who got caught up in a chain of murders. Komaeda then states that later on in the story you find out the culprit who was behind said murders, was none other than herself, the killer the schoolgirl was trying to catch, was herself. When he asks Hinata what kind of story does he think of that, Hinata has no idea how to response or what exactly Komaeda was getting at. By this time, it's possible that Komaeda knows that besides Hinata being part of SHSL Despair, Hinata'scurrenttrueidentityisKamukuraIzuru, the man who turned into a mass murderer during the very first mutual killing game. Which also leaves the unanswered question of what motive he had for starting that conversation to begin with.
Genre Savvy: When they arrive on the island, he promptly guesses they're going to be forced to kill each other. Once Monokuma shows up, he's right on the money.
Go Mad from the Revelation: Discovering the Awful Truth really didn't do his psyche any favors, though it's debatable how much of his subsequent behavior was genuine and how much was part of his plan.
Green-Eyed Monster: His actions arrogant attitude toward Hinata from Chapter 4 on can be interpreted as a form of jealousy, as he learns from a Monokuma file given to him in the Final Dead Room, that Hinata's talent is the Ultimate Hope, a role that Komaeda always wanted to become.
Heroic Sacrifice: Fully intended to sacrifice himself to kick-start the murders so that the others might be saved. Also fully believed that would be the best use of his "less talented self" instead of a Senseless Sacrifice.
I Just Want to Have Friends: Stated in his free time events that, despite his cheerful front, he has absolutely nobody in his life, everyone having left him due to his self-righteous beliefs to the point where all he wants is another person's love. He's also implied to push people away due to his talent. His Dangan Island ending provides further support for this, wherein he asks Hinata to be his friend after fifty days and only because he sees the rest of the school trip, along with the realization that true hope was inside him all along, as "bad luck."
Ill Boy: In his free time events he reveals he was diagnosed with stage three malignant lymphoma and concurrent frontotemporal dementia before winning the Hope's Peak lottery. It's left ambiguous whether he was really telling the truth, though the Spin-Off manga set from his point of view and the Setting Material Collection both lend support his claims.
Kick the Dog: After he discovers the true identities and pasts of his remaining classmates in Chapter 4, he's full of these. Most notably during trial 4, where he doesn't drop referencing back to Hinata's status as a Reserve Course student.
Kick the Morality Pet: He doesn't sugar-coat it at all when explaining to Hinata what information he found from beating the Final Dead Room game. If anything, that's when he begins to drop a bit of the Nice Guy attitude. From then on, he continues to antagonize him and the other remaining students. He also kept bringing up Hinata being a Reserve Course student over and over again during the trial, and belittles Hinata on how he usually handles the murder cases and trials. He even tried to summarize trial 4's case because he found Hinata's way of doing it very long. Ouch.
Killed Off for Real: Possibly. While the other "dead" students bar Nanami are simply rendered comatose and Naegi implies they'll eventually wake up, Komaeda's statements on the laptop found following his death regarding his role being finished and his lack of presence in the glitch scenes hints he might very well be dead due to his illness.
Kill Them All: After he discovers that the students were once members of Ultimate Despair, he plots to kill everyone on the island (except for the mole, who is innocent) so he could "rid the island of despair" and earn the title of Ultimate Hope, though his video at the end seemed to indicate that he felt he would become a cornerstone of hope regardless of which side would survive.
Kill the Ones You Love: Was planning to do this to the remaining classmates(the members of SHSL Despair), and Hinata (as much as he cares for him) so that despair will no longer exist on the island.
Knight Templar: His attempt to "save" Nanami by making her kill him and trying and have his fellow former members of the SHSL Despair killed by voting for him by making he death appear to be a suicide shows how dangerous his black and white "Hope vs. Despair" mindset made him.
Light Is Not Good: His ramblings about hope indicate that he's dangerously obsessed with it. So obsessed that he's willing to kick-start the mutual killing by trying to cause the first murder, just to challenge everyone's hope so that it can become stronger. During the trial it doesn't take long to discover that he's not entirely stable.
Lonely Rich Kid: Implied in his free time events. He got a large inheritance, but that came as a result of his parents' deaths.
Love Freak: Well, "Hope Freak" technically. Acts like this both when Monokuma reveals the "murder" game, and when Togami is murdered, and Komaeda swears to prove none of the students is a murderer. He isn't taken seriously either time.
Love Martyr: Doesn’t care that his love and admiration for his classmates are one sided, but is genuinely surprised and a bit hurt that Hinata no longer trusts him. Then subverted when he finds out the truth behind their past and who they are. This even carries over to Dangan Island when he states that he doesn't mind if Hinata yells at him. His expression of the thought of Hinata hating him seems to bring him great discomfort and fear.
Love Redeems: Sorta. His interactions with Hinata help remind us that although Komaeda has Lack of Empathy moments, he does have genuine love and care towards Hinata. Doing his free time events help support this. Though this does tend to get subverted after he discovers Hinata's true identity and past as a member of SHSL Despair. Even taking in the events of what he was doing as a member of SHSL Despair, Hinata's still the only person whose interactions and strained friendship brings out the best and good in Komaeda.
Manipulative Bastard: Played with. Komaeda's style of manipulation is nowhere near what's generally considered to be the actions of a manipulative bastard; instead, he tends to plant ideas with the confidence that things will work out how he plans, such as in the first chapter, when he "lets" Hanamura find him taping the knife under the table for the sole purpose of spurring Hanamura into action by giving him the idea of murdering him (Komaeda) to save whomever he was planning on hurting at the party. Of course, that goes sour when Togami ends up dead instead, but it's not for lack of trying.
The McCoy: An extreme version of the trope, he relies on his belief in hope and his talent to get what he wants.
Nice Guy: Definitely at first, although the events of the first chapter cause the others to stop seeing him as this.
Nice Job Breaking It, Hero: Repeatedly and enthusiastically, partly due to his oscillating luck and partly due to his mental instability. The biggest example, though, is definitely his "arranged murder." If it had worked as intended, it would have given Junko everything she wanted in one fell swoop, and it still managed to kill off Chiaki and Usami right before some moral support from an unbiased source would have been really helpful.
Nightmare Face: Makes one in first trial, in a Call Back to the face Enoshima made just before her execution in the original.
No Kill Like Overkill: How does Komaeda go out? He's tied up, stabbed repeatedly in both legs, has his left arm slashed up, his right hand impaled with a knife, and then impaled through the stomach with a spear and poisoned with highly lethal toxic fumes. Other than the last one, which he tricked someone else into doing, all of these are self-inflicted.
The Not-Love Interest: Zig-zagged with Hinata. He starts out looking this way, as he's Hinata's closest ally who he gets some Ship Tease with, and later betrays him and causes the first murder, something very simular to Maizono from the first game, who was Naegi's decoy love interest. Afterwards, it gets rather complicated, as Hinata does try to understand Komaeda, despite openly saying he's afraid of Komaeda, something that helps him win the Chapter 5 trial. Komaeda's actions in Chapters 4 and 5 put further strain their relationship, though there is nothing that indicates that they cannot reconcile after the game is finished and their relationship is ultimately left unresolved, although Hinata did almost forgive him at the end of his fifth freetime event, in which (along with in bonus materials) it is made clear that it's definitely not platonic on Komaeda's side. Their relationship takes a more positive turn in Dangan Island. However, rather than becoming anything more, Komaeda only asks him to be his friend after 50 days, at which point he has experienced enough bad luck for something as good as that to happen.
Not So Different: Points out to Hinata that they both hold Hope's Peak in extremely high regard, and that he doesn't feel any "special aura of talent" from Hinata like he does from the others. The two are frequently mirrored in official art.
Obfuscating Stupidity: One of the smartest members of the cast, if not the smartest, whose perceptiveness and reasoning skills often result in him solving the case before the trials even start. However, he deliberately invokes this trope on himself during trials by generally acting ignorant and praising others for noticing clues that trash like him would've never picked up on! This is partially because he prefers to stay on the sidelines until he can decide whether to aid the culprit or the students, and partially because he wants to see the other students' hope shine brighter by letting them take the spotlight.
Only Friend: He considers Hinata the only person on the island to have any genuine meaningful connection with.
The Only One Allowed to Defeat You: He takes it upon himself after discovering everyone’s true identity to personally end SHSL Despair once and for all. This includes himself.
Ordinary High-School Student: In contrast to the other students, since he was only accepted into Hope's Peak as the result of a lottery, rather than because of any sort of extraordinary, practical talent. This still puts him above Hinata when you find out that Hinata doesn't have a talent. Later subverted when it turns out his luck is actually genuine and scarily powerful, while his life has been anything but ordinary thanks to the influence of his luck. It's arguable whether or not he himself is ordinary underneath it all.
Please Kill Me If It Satisfies You: After his actions alienate him from his classmates, he cheerfully invites him to kill him if they like, in part because he sees himself as more expendable than the other students. He mentions in his spinoff manga that acting as a stepping stone for hope, even if it means dying, is something of a long-cherished wish of his.
The Pollyanna: Though he freely acknowledges when things are going badly, he keeps a positive attitude about it, and tries to inspire others to do the same. Unfortunately, this tends to creep them out more than it inspires them, especially when he's waxing harmonic about how people dying will just make everyone else's hope shine even brighter!
Psycho Supporter: He idolizes his other Ultimate classmates and would love nothing more than to see them excel, even at the cost of his own life, which is what leads to him trying to cause the first murder.
Red Herring: Despite sharing a talent and voice actor with the previous game's protagonist, and having a similar name, Komaeda is not Naegi, nor does he have any connection to him other than serving as an Evil Counterpart of sorts. Apparently, it was part coincidence and part misdirection on the part of the writers.
Red Right Hand: In the real world, he replaced his left hand with that of Junko Enoshima, supposedly so that he could become one with "Super High-school Level Despair". He's incapable of actually moving this replacement hand, however.
Self-Deprecation: He describes his good-luck talent as not as special as the talents of the other students. However, this is taken to an extreme: he thinks that he is trash compared to the other students and is more than willing to sacrifice himself for their sake.
Senseless Sacrifice: Despite his suicidal obsession with dying for hope, his "murder" ends up being this. Nagito's Rasputinian Death and arranged murder to smoke out the "traitor" or rather, to ensure the "traitor" would be the last man standing succeeds only in cutting off two of the only useful sources of support the students had before the endgame, playing right into Junko's hands. And if his plan had worked as intended, it would have given Junko everything she wanted.
Sole Survivor: Of the tragedy that claimed both his parents. Supplementary materials hint that even before his parents' death, the other people on the plane were already killed (presumably by the hijacker).
Stepford Smiler: Type A. His last free time event and his Dangan Island ending both hint that despite his cheerful attitude, the cycle of good luck and bad luck he's dealt with his whole life has worn him out so much that he wishes to die during the school trip.
Suicide by Cop: What his plan in Chapter 1 is implied to be, a fact confirmed by his spinoff manga.
"There are two kinds of people in this world: Those who are born with worth, and everybody else."
Token Evil Teammate: Komaeda makes it clear that he will stop at nothing to "make the Hope of the students shine", from manipulation to causing a murder. His many complexes and neuroses, plus the very real degenerative brain disease he's suffering from, have left him both suicidal and homicidal.
Took a Level in Jerkass: After seeing everyone's full profiles, his attitude towards them completely shifts, to the point of outright antagonizing them.
Trauma Conga Line: Thanks to the constant cycle of bad luck and good luck he's gone through during his life. An example he cites is watching his parents die by being struck by a meteor, only to inherit a vast sum of money from them.
The Unfettered: He often states that there are exactly two things that he believes in absolutely: his own luck, and Hope. This makes him a very dangerous individual.
Unreliable Expositor: Deliberately invokes this on himself by freely admitting he could be lying at any time. It's implied he generally isn't, however, with him freely admitting to the only times he does lie out of necessity. Supplementary materials also confirm several claims he makes in the game.
Villainous Breakdown: In Chapter 1, when Hinata shows he's the only one who could've gotten to the table with the knife, he has a Laughing Mad-type outburst complete with spiral eyes. Also has one in Chapter 5, but it's subverted in that we find out it was part of his bluff, which raises questions about the first one...
Walking Spoiler: He is one of the many reasons this page has to be spoiler tag free. It comes as a natural result of his characterization for most of the game being starkly different from his initial characterization, and his death being involved with one of the game's major plot twists.
Well-Intentioned Extremist: Sincerely believes that the best way to make everyone's "hope" stronger is to cause despair. After learning the Awful Truth, he becomes even more determined to end despair no matter what it takes.
White Hair, Black Heart: It's debatable whether he truly has the black heart, but his morals are definitely questionable.
Why Don't Ya Just Shoot Him?: Invoked in spirit, if not in lethality, following the first trial. When all is said and done, Nekomaru and Soda knock him out and tie him up hand and foot in the old building for most of the first half of Chapter 2, which was probably the most rational response, all things considered.
Wild Card: States several times that he's on the side of hope, and often sides with the culprits as a result, although he sometimes gives up on them for various reasons, such as when evidence against Hanamura piles up.
Will Not Tell a Lie: Is stated in the setting material collection to be an "honest person". He does lie, but only when he views it as absolutely necessary.
Xanatos Gambit: His Thanatos Gambit in Chapter 5 is this, to some extent, though it's easy to miss. Whether the students or traitor survive, he still believes his actions will become the cornerstone of hope, or at least that hope will be created, if they can overcome the despair-inducing case he created—hence why he gives the password to the students in his final message, despite knowing that the traitor would already have this knowledge, and his statement that it doesn't particularly matter to him who survived, which would otherwise contradict his motives completely.
You're Insane!: By the end of the first trial, every other student thinks this of him. Some have even said several variations of the phrase to him by this point. And according to one of his free time events he really is mentally ill, though he points out he could just be lying for sympathy points, other sources imply he really wasn't. Hinata comments on how "insane" his plan is at multiple points in the Climax Inference of Chapter 5.
Hinata: (describing Komaeda wounding himself to make it look like he was tortured) The true madness of his plan began there. He started doing something that no one in their right minds could have done.
An absent-minded girl who loves video games of all genres (even bad games) and is skilled at playing them. She tends to become so absorbed whilst playing that it's hard to hold a conversation with her, and has a habit of pausing for long periods of time while she mentally composes what she wishes to say. She is the mole of the group, placed there as an inside observer by the Future Foundation. Nanami is actually an Artificial Intelligence from the same cloth as Usami, acting as a Non-Player Character within the New World program. She is the accidental culprit of Chapter 5, but foils Komaeda's plot to kill all of the students (except her) by confessing to the "murder", forcing her execution alongside Usami. Despite this, she returns in final trial, giving Hinata the hope to continue forward.
Accidental Murder: Played with. The fact that she killed Komaeda is indeed an accident, but Komaeda was banking on his luck that the one who would kill him with the poisoned bottle would be the "traitor", and she is.
Adorkable: Especially when she puffs up her cheeks to show she's angry like a child having a tantrum.
A Friend in Need: Pulling a Heroic Sacrifice doesn’t stop her from wanting to help out her friends again even after she was already supposed to be dead. Regardless that she would most likely be erased from existence, she talks Hinata into choosing accepting both hope and despair so that he can move on to create a future for he and the others. As long as they do that, she tells Hinata that everything will be okay and that they’ll always be friends no matter what.
Artificial Intelligence: Since she is really just an NPC in the Jabberwocky simulation. It turns out that Chihiro Fujisaki, who created another artificial intelligence in the first game, created her as well.
Berserk Button: She drops the space cadet routine and gets very serious when mutual killing is involved.
Big Damn Heroes: Returns in Chapter 6 to give Hinata a much needed pep talk that allows him to overcome Enoshima's despair speech.
Character Tic: Chiaki will often pause for a moment before speaking, needing time to sort what she wants to say first.
Cloudcuckoolander: Tends to be a little slow in responses when talking to her, often putting things in a gaming perspective. But when things get serious...
The Confidant/The Conscience: When the times calls for it, she will act as both to Hinata, most blatantly in Chapter 4: when he was about to go into the Final Dead Room, Nanami talks him out it, reminding of how pointless it is and that he shouldn’t push himself. After the dispute with Komaeda(after he revealed that Hinata was a reserve course student), he confidents in Nanami that regardless of how he’s feeling, he will continue to pursue investigating Nidai’s murder. Second most blatant example, is when hits his Heroic BSOD during Chapter Six. He lets out everything that has been dumped on him, and is at a loss of what to do. Nanami talks him out of being indecisive, and gives him the strength to move forward.
Cruel and Unusual Death: Nanami and the rest of the Usami/Monomi units are in a room with pixelated models, when Monokuma comes in with a tank and starts to shoot at them. Nanami suddently spots an exit and she and the Monomis run, followed by Monokuma in a Pac-Man-like vehicle that crushes all but one of the Monomi units. However, Nanami and the last Monomi reaches a dead end. With no more escape routes, Monokuma begins dropping Tetris blocks in the area, eventually crushing the last Monomi, and then Nanami. The blocks then explode due to Monokuma forming three perfect lines.
Designated Love Interest: To Hajime, to an extent. This is lampshaded by Souda in the fifth class trial, although the romance arguably never goes beyond Ship Tease, as a result of Chiaki's death in the fifth chapter, and fading from existence after the shutdown of the program.
Deuteragonist: Similiar to Kirigiri in the first game. Which makes it all the more surprising when she turns out to be the "traitor", as well as the accidental "culprit" regarding (the other deuteragonist) Komaeda's murder in Chapter 5.
Disappeared Dad: She speaks about her dad (a programmer) in the past tense, hinting that he died. Chapter 6 reveals that her "father" was Chihiro Fujisaki, the Ultimate Programmer who died in the original game.
Expy: Most obviously of Fujisaki (similar titles, designs and official art poses) and Kirigiri (similar role, color scheme, and relationship with the player character). Her true nature also gives her a lot in common with Alter Ego, which makes sense since he is her "brother" and both of them take after their "father".
Friendless Background: She implies that this is the case, indicating that she's never been to an amusement park with friends, not having any friends until she met the other students. The truth about this matter seems related to her status as an Artificial Intelligence.
Genius Ditz: She's a savant when it comes to playing video games, and her wide experience of genres (murder mystery, edutainment, etc.) gives her an astonishing range of general knowledge, so much so that she's one of the best members of the group to talk to when you need insight into a murder case. In fact, there's only one genre of game that she's bad at: dating sims.
Genre Savvy: Because of all the games that she plays. After the first murder, she is the first to suggest that someone be nominated to guard the body just because "that's the kind of thing that happens in closed-circle murder mystery games".
Get a Hold of Yourself, Man!: Slaps Akane in Chapter 5 to bring her to her senses when she's freaking out over Komaeda's plans, and trying to strangle Komaeda to death.
Hair Decorations: Her hairclip is the shape of the spaceship from Galaga. Fits well with her status as gamer and "space cadet".
Heroic Sacrifice: In Chapter 5, she works out that Komaeda's plan was to kill everyone but the "traitor" (her). Instead she urges everyone to vote her as the murderer, relying that Komaeda's good luck held and she was the one who accidentally killed him.
Hidden Depths: She proves remarkably competent at the trial despite her sleepy demeanor, being the one to both expose Komaeda's act and put forth the idea the killer wasn't under the table in the first trial. She also tells Komaeda to please stop talking, in a polite but firm tone, to finally interrupt his antics.
I Know Mortal Kombat: Her video game experience makes her surprisingly useful for investigating the game's murders. For example, she maps out the Twilight Syndrome crime scene using her experience from dungeon crawler RPGs.
Incorruptible Pure Pureness: As an AI who is trying to help the former SHSL Despair students rehabilitation process she is completely immune to any of Monokuma's motives since she can't be driven to kill any of them... Which is why Komaeda had to use his luck to make her his murderer.
Killed Off for Real: ...Possibly. Depends on whether you interpret her last words literally or just symbolically. Like most of the character's fates at the end, it's left ambiguous.
Japanese Honorifics: She uses "-kun" on male students' last names and "-san" on female students. After her connection to Monomi is revealed, she starts referring to her as "Monomi-chan."
Let's Get Dangerous: When Komaeda tries to get everyone to give up on the first trial by insisting there's no evidence and no way they can catch the killer, she suddenly stands tall and shoots back with a "You've got that wrong!" Even though she softens it a moment later by adding "...I think", it signals the start of a devastating counterargument.
The Lost Lenore: Hinata, though more notably, and the survivors are not happy when they find out that Nanami is the culprit for Komaeda's death. The news of Nanami just being a NPC devastated them because she cannot exist in the real world, despite being one of the nicest people out of the whole cast. As they return to the real world, they all want to remember their friendship with her, and keep the memory of Nanami within them.
The Mole: For the Future Foundation. However, in this case she has the students' best interests at heart.
Nice Girl: She's kind and good-natured to others. Her only killing ends up being accidental, as a result of someone who wanted her to end up as the culprit.
Nerves of Steel: Just like Kirigiri Kyouko, she will hardly ever lose her calm personality even under intense pressure. Hinata even calls her this, and praises her for it.
Non-Player Character: What she really is in-universe, since the setting of the game is actually a virtual reality.
Shout-Out: Nanami carries on Yamada's legacy of regularly making video game references.
Significant Birth Date: Her birthday is on March 14. March 14 was also Chihiro Fujisaki's birthday, since he created her.
Sleepyhead: She has a habit of falling asleep in the middle of sentences. A free-time conversation reveals that she frequently plays video games for so long that she forgets to sleep.
Sympathetic Murderer: Can't get more sympathetic than being the murderer because you accidentally grabbed the wrong bottle in a 1 in 16 chance. Then pulling a Heroic Sacrifice to ensure that your friends would continue to live.
Verbal Tic: Has a habit of adding "...I think." to the end of her sentences.
Wham Line: Midway through the fifth trial, she says that all Komaeda's efforts, up to and including arranging his own death, were intended to draw out the traitor, but the traitor is unable to reveal their identity. Hinata then realizes that Nanami is indirectly admitting to being the traitor.
What Would X Do?: She asks Saionji what she would think Koizumi would say in response to Kuzuryuu attempting Seppuku.
Why Did It Have to Be Snakes?: Sort of. It turns out that there is exactly one genre of video games that Nanami isn't good at playing, as Hinata finds out during Nanami's first free time event. It's dating sims.
The scion of the wealthy Togami family, and one groomed to become a success since childhood. Togami immediately takes the position of leader amongst the group, claiming that he will use his superiority to lead them all to safety. Intelligent, calculating and utterly ruthless, Togami is a force to be reckoned with. Also, he really likes food. He attempts to prevent a murder in Chapter 1, and although he manages to foil Komaeda, he is accidentally killed by Hanamura (who was gunning for Komaeda). Later on, Hinata discovers that "Togami" is actually a person without a home, relatives or even a name: the Ultimate Imposter, who could only live by assuming the guise of another person.
Acrofatic: Hinata notes that he moves surprisingly fast for a person of his size. He also had to pull off some incredibly fast moving during the blackout, being on the opposite side of the room from where Komaeda hid the knife.
Ambiguous Gender: Even though the Impostor uses a male persona throughout the course of the game, their gender is officially unknown.
Big Eater: Togami seems to have developed an obsession with food since the last game, which might explain his weight problem... but in reality this is a trait particular to the Impostor. In one of his Free Time events, he tells Hinata that he finds comfort in eating fast food, as no matter where he goes it always tastes the same - and implies that it's one of the only consistent things in his life.
Blond Guys Are Evil: Subverted. This time Togami's heart seems to have grown along with his gut, and he takes charge to prevent his classmates from being murdered (which would have been unthinkable from him in the past). Of course, he's not the real Togami.
Blue Blood: As the heir to the Togami family... or not.
Character Development: In Chapter 1 of Dangan Ronpa 2, when the game gets switched back to the "murder" format, Togami instantly decides to invite everyone to a party on the pretext of strengthening their bonds, when really he's trying to arrange to do away with all the murder weapons and have everyone where he can see them. That he's thinking of the others at all is a stark contrast to his selfish desire to graduate by winning the game in the previous Dangan Ronpa, so it looks like Togami's undergone a lot of character development since then... It's subverted, however, as the reason Togami seems nicer in this game is because it's not really him, but an impostor. No actual character development has taken place after all.
Dark and Troubled Past: He implies that there was a time in the past when he couldn't trust anyone and no one could trust him, which is why he's taking precautions regarding the party. It's unclear whether this is at all related to his joining SHSL Despair.
Expy: He's kind of a reverse Mukuro Ikusaba. Both Mukuro and "Togami" are imposters, both of them seem to have lived rather rough lives, and both of them are among the first characters to be killed in their respective games. However, Mukuro (as the fake Junko) is a seemingly unimportant character that turns out be important after she dies. By contrast, the imposter is a seemingly important character who turns out to be unimportant after he dies.
Fat and Proud: He makes it quite clear that he gained all that weight between games on purpose. He never gets to explain why, though, mostly because there isn't a reason.
Fat Bastard: Subverted, see Blond Guys Are Evil above. The reason for his fatness is explained, naturally.... but not until long after his death - it's not the same Togami. It's someone without a name, relatives or home, whose true talent is Ultimate Impostor; they have nothing to their name, so the only way for them to "exist" is to impersonate another. If you pursue their route in Dangan Island, they freely acknowledge that what they're doing is still wrong, however, and Hinata forgives them so Hinata can get to know the impostor better as a friend, which greatly moves the impostor.
Formerly Fit: Subverted, since as it turns out, that's not actually the real Togami.
Genre Savvy: Togami doesn't take any chances during the Chapter 1 party, and makes sure to lock up every single item that could conceivably be used as a weapon, right down to the utensils and food skewers. Being genre savvy helps him realize a murder plot was afoot right off the bat, and he succeeds in preventing Nagito's murder attempt. Unfortunately for him, Hanamura was also trying to stop Nagito by killing him, and this leads to Togami's end when he is mistaken for Nagito.
Japanese Pronouns: He typically uses omae on Hajime, but briefly switches to using the more polite kimi on Hajime, switching back when Hajime finds the change very uncharacteristic of the Togami he knows.
Jerkass Façade: It's hinted that the Impostor isn't nearly as much as a Jerk Ass as the actual Togami in spite of initially appearing to be as stand-offish and arrogant; he spends a surprising amount of time in-game trying to assure people and make sure there won't be killings. This is especially noticeable and eventually confirmed in his Freetime Events.
The Leader: A Type II who immediately steps up to take charge after Monobear takes over.
Man in White: Looks familiar, but there's something different about him... must be the suit. Considering the name "Byakuya Togami" translates to"Whitenight Tengods" one could say this new look suits him rather well. It also works as a pretty good metaphor for the character too, since as the SHSL Imposter this "Byakuya Togami" persona is just as much an outfit they are wearing as the suit itself is.
Mock Millionaire: Or multi-billionaire as the case may be, either way they aren't Togami.
No Name Given: Neither Hinata or the audience learns their real name. Their final free time event reveals that they don't have one.
Massive Numbered Siblings: In the first game he tells Naegi that he was the youngest of the fifteen children of the Togami family head; here, he tells Hinata he's one of a 108 half-siblings. The real Togami's number is probably more accurate.
Nice Guy: In the few times we see his real personality he's shown to be very polite and modest. In other words: absolutely nothing like the real Togami.
Not So Different: Compares Kuzuryuu to how he used to act, and seems very amused by that. Kuzuryuu doesn't appreciate that.
The Proud Elite: While still acting arrogant, he's very quick to declare that he will ensure everyone's survival, and is equally quick to recognize Hinata's potential and try to recruit him as his assistant.
Red Herring: Doubly so. It initially seems that Togami will be an important character, and he has insight about what is really occurring on the island. Then he becomes the first murder victim. Then it turns out he wasn't really Togami but an imposter...but the reveal is treated as something unimportant. In fact, the imposter is so unimportant that they literally have no identity of their own. In short, he seems like he'll be relevant to the plot, then he gets killed, then he turns out to have never been relevant. And that was probably the point.
Sacrificial Lion: Survived the first game, only to become the first to die here. Subverted however, since he is not the real Togami, though his death still makes him qualify.
Serious Business: During Free Time events, Hinata learns that the "body mass index" and the qualities (or lack thereof) of various kinds of meats is this trope to him.
Sudden Sequel Death Syndrome: Surviving the first despair game doesn't mean he'll survive the second... Subverted when it was revealed he was an imposter.
Taking the Bullet: Nanami suggests the possibility that he saw Hanamura moving under the floor with his night scope and actually moved to shield Komaeda from him with his own body. Komaeda laments the irony of this, as his Spinoff manga states this to be true.
Tempting Fate: Declares that there will not be a single victim under his watch. Guess who the first victim is?
Walking Spoiler: In more ways than one. While the fact that his presence gives away Togami surviving isn't massive, given the sheer amount of Late-Arrival Spoiler the franchise is known for, the fact that he is an impostor is only revealed in the Chapter 5 investigation, well after he died.
A highly eccentric individual who is rumoured to be able to speak to animals. Tanaka talks like a cartoon supervillain and aspires to use the dark arts to rule the world. He keeps a colony of hamsters, who he has dubbed the "Four Dark Devas of Destruction", under his scarf. He is the culprit of Chapter 4, murdering Nidai due to being unwilling to simply give up and die when faced with choosing between committing murder or starving to death as a result of Monokuma's "motive". He is found guilty and executed by Monokuma, trampled to death by a stampede of animals.
Antiquated Linguistics: He talks in the manner of a stereotypical "evil-overlord-to-be," which is why it comes as a shock to Hinata when his special skill turns out to be "Animal Breeder."
Berserk Button: When he's exposed as the murderer, he doesn't put up much of a defense, but is infuriated when Komaeda suggests that he took Nidai from behind. He later points out that Nidai could have run or called for help, but instead chose to stand his ground against him.
Black Magic: He claims to be a practitioner of the dark arts, and that his "Animal Breeder" title is just a front.
Blatant Lies: His self-proclaimed motive for killing Nidai. When asked if he intended to sacrifice himself and Nidai in order to satisfy the murder requirement for leaving the Fun House, he denies it and attempts to push his Evil Overlord image as normally...before giving a rousing speech about the importance of hope and not giving up on life even in the face of despair. Needless to say, nobody is convinced.
Bunny-Ears Lawyer: Specifically, Tanaka's "bunny ears" part of this trope is his "chuunibyou" condition. Since middle school, he has been deluded into thinking he may be above ordinary humans, and yet, he earned his Ultimate animal breeder status for a reason.
Card-Carrying Villain: If his Ultimate Despair version of himself is anything like the version we see in the game, he was possibly one to rival even Enoshima.
Cloudcuckoolander: Half the time he seems to be stuck in his own world and not paying as much attention to the events around him as he should. It's all but stated that he's a chuunibyou.
Deathbringer the Adorable: His hamsters are called the Four Dark Deva Lords of Destruction. They're not completely harmless, though: one of them makes it possible for Tanaka to murder Nidai by sneaking up and pressing a button to shut Nidai off until Tanaka can tie him up in a place where a struggle will get him killed.
In Chapter 1, Tanaka refuses to give up on recovering his earring (which he claims is instrumental to the fate of the world), even if it has fallen under the floorboards. Hinata wishes he'd use his determination for something more constructive to the investigation, though. Ultimately, it does prove to be relevant, since if Tanaka could find a way under the floorboards, so could the killer...
An extremely rare negative example of this trope, since this is his motivation for being the culprit in Chapter 4. Specifically, to provide Chapter 4's "motive", Monokuma trapped all the remaining students in a building, then cut off their food so they'd be in danger of starving unless a murder occurred. Tanaka didn't want to just roll over and die and give up...which is why he murders Nidai, since he wanted to do whatever he could to move forward. Since Hinata manages to figure out the culprit was him, however, his determination didn't help him.
Evil Laugh: A ridiculously exaggerated one that leaves Hajime speechless.
Face Death with Dignity: He's the fourth culprit, but accepts his fate, even giving the others a Rousing Speech about not giving up. Monokuma drives a stampede of animals towards him, and he takes a moment to place his hamsters out of harm's way, and then is one of the few people in the series who actually has somewhat of a fighting chance against his execution: he draws a huge "magic circle" meant to stop the stampede...but it doesn't work and the animals crush him to death, though he dies with a smile while being carried to heaven by his past pets.
Friend to All Living Things: He loves animals and vice versa. During his first Free Time event, Hinata learns that Tanaka even runs his own blog advising others how to properly care for animals.
Foil: Souda latches onto him as a rival simply because Sonia likes him. They proceed to spend quite a bit of the later trials arguing.
Going Commando: When the player receives his underwear for clearing his free time events, it's transparent, which may indicate this... though the description claims that his underwear is just invisible to those with "low astral level eyesight."
Heroic Sacrifice: It's implied that this is part of the reason he and Nidai tried to kill each other. Even if he didn't get away with it, at least the others would get out alive. When he's finally caught, he happily accepts his fate. Hinata and Nanami ask if this is his motive, and he denies it in his usual manner, although Hinata is unconvinced.
I Did What I Had to Do: Downplayed. He accepts his fate, and doesn't try to justify his actions, but has this to say about murdering Nidai.
Tanaka: You must agree that this is a better outcome than us all starving to death in that surprise house...
I Just Want to Have Friends: Implied in Chapter 2, when Hinata notices he's probably sulking due to his not being invited to go on the beach trip. His free time events make explicit the fact that he has an easier time dealing with animals than people.
Large Ham: Boy howdy. When he's not talking like a supervillain, he's yelling out his words. He's called Gundham in the dub for a reason.
Lethal Chef: Not him, but apparently his mother. He goes so far as to claim her cooking poisoned his entire body.
Luminescent Blush: Which he tries to hide behind his scarf. Happened a couple times when Sonia takes his Overlord persona seriously, implying he doesn't normally expect people to take said persona seriously, plus when she coos over his hamsters.
Mark of the Supernatural: Tanaka has a few noticeable features that fit this trope, such as his mismatched eyes, his black and gray hair, and the scar over his left eye. Of course, these features are most likely not natural - Dangan Island even reveals that the red eye is a contact - so all of these are really Gundam's attempts to invoke this trope and look like a practitioner of the dark arts.
Miles Gloriosus: Seems like he would be this - with all the bravado he displays, he certainly qualifies - but possibly subverted when he becomes the fourth murderer.
Morality Pet: A light example. While Gundam isn't truly evil or villainous, his hamsters play this very straight, showing that despite his Overlord persona and his near-complete lack of social skills, he's ultimately a good person. His interactions with Sonia where he gets flustered or gentle with her further humanize him, as well.
Mr. Imagination: He fabricates a bizarre super villain-like persona for himself, treating his collection of pets like evil minions.
The Nicknamer: While he usually refers to people by their surnames, he'll sometimes call the other students by monikers such as "the pretentious one" (Hanamura), "the substantial one" (Togami), or "the thoughtful one" (Nanami).
Pet the Dog: Well, obviously, despite him talking like a future evil overlord, he's nice to his hamsters (as you'd expect from a Super High-School Level "Animal Breeder"). But even as he's being executed for murder in Chapter 4, he takes the trouble to place his hamsters out of harm's way... and when the stampede Monokuma's using to execute him finally tramples him to death, animal angels come down from heaven to retrieve Tanaka while his hamsters watch.
Poisonous Person: Claims he is this, as a result of his mother's vile cooking over the years.
His first name is a very obvious reference to a certain long-running franchise, though in this case it's written in kanji rather than katakana. Despite that, the Shout-Out is definitely still intentional, as proven by his execution being named after the first episode of Mobile Suit Gundam ("Gundam Falls to the Earth" and "Gundam Rises Upon the Earth" respectively).
Individually, his hamsters are all named after the four biggest-selling Shōnen manga magazines: "Mirage Silver Falcon" Jum-P (Shonen Jump), "Star-destroyer Grey Fox" Sun-D (Shonen Sunday), "Invading Black Dragon" Cham-P (Shonen Champion) and "Steel Red Elephant" Maga-Z (Shonen Magazine). They also borrow from the Ham-Chat language of Hamtaro.
Spell My Name with an "S": Most official sources give his name as Gandamu, probably due to it being written in kanji (眼蛇夢) rather than katakana (ガンダム). In the English localization, it's romanized as "Gundham" (the H is silent) for copyright reasons.
A mechanical genius with the ability to fix anything. In spite of his scary appearance, Souda is actually rather timid and is prone to freaking out at the drop of a hat. He survives the final trial and returns to the real world with the other survivors.
Abhorrent Admirer: A gender-flipped personality based example to Sonia. At first she just tries to completely ignore him and his behavior towards her, but as he keeps getting worse she even is quite disappointed that he's not the culprit of Chapter 4 (and this is before finding out that Tanaka, the guy she does like, is the murderer). From that point on, she shows more open hostility towards him.
Abusive Parent: His father beat the hell out of him after finding out he was skipping class trips. Oddly, he didn't actually care if Souda skipped his regular classes, and provided no support to deal with his school bullies other than letting him stay home and work in their bike shop.
Adorkable: Some of his antics can come across as this, but most of the time it is closer to a subversion: One of his portraits may look cute but he is often talking about things which scare his fellow students when it is used, like his obsession with Sonia or messing around with Nidai's body after he becomes a robot.
Bad Liar: Tends to fall very quickly into Implausible Deniability when he tries, such as when Nidai reveals they tied up Komaeda or when trying to get invited to the girls' beach party.
Beneath the Mask: Souda tries at times to act more like the image his physical appearance would suggest, with little success. (His Free Times eventually reveal it's a deliberate act he's trying to assume in hopes of becoming better liked.)
Butt Monkey: A common target for Monokuma and Saionji, his tendency to end up the butt of jokes and having horrible things esculate to the point that in Chapter 5, he flat-out gets Blown Across the Room by an explosion. Deconstructed in how badly this affects him: he gets very upset very easily, and in Chapter 4 completely melts down when the stress of Monokuma's latest motive combined with all his latest problems get to be too much.
Compressed Hair: That wild mane in his official art is normally hidden under a simple black cap.
Covert Pervert: In Chapter 2, the girls decide to have a girls-only "beach party", and Souda goes to quite a lot of trouble to figure out a way to get himself and Hinata invited to the party as well since the girls will all be in swimsuits. In Sonia's case he's disappointed, however, because she shows up in a wetsuit instead, and a wetsuit covers the entire body except the head. He's surprised for like two seconds before deciding he's totally okay with this.
Dark and Troubled Past: Comes from a poor background, and was heavily bullied in middle school. Casually refers to his father beating him for not going on class trips. Someone he thought was a friend was actually exploiting his trust to get good grades. This led to him drastically changing his image to try and fit in better, and he hoped Hope's Peak would give him a fresh start.
Delinquent Hair: Partially shaved but growing back, other parts going a bit past his shoulders, a braid opposite the buzz cut side and it all forms an almost shark-like fin... Not that you see it all that much due to the hat.
The Engineer: Technically he's actually a mechanic, but this trope is essentially his role in the game.
His angular, wild-haired design makes him resemble Kuwata, and he shares several speech patterns with him. This is combined with Ishimaru's extreme expressiveness and Inelegant Blubbering and Hagakure's Butt Monkey status and tendency to panicking and overreacting, yet be surprisingly capable of playing the Straight Man if dealing with the wackier members of the student body.
In addition, one could also say he's an expy of Fukawa, as they both are very open about their one sided crushes on attractive upper-class blondes that want little to do with them. His former appearance even sounded similar to how she looks (or if his teeth are naturally shark-like, Syo) and they also both have a very long histories regarding being bullied by their peers in school.
Extraverted Nerd: Bright clothes, brash attitude, and seems oblivious to how he comes off. Actually pretty self-aware, at least of how poorly he used to be recieved, and acts out in ways hes thinks will make him friends.
Face of a Thug: He might look like a punk, with his narrow eyes and shark's smile, but that doesn't match his personality at all.
Fangs Are Evil: As a SHSL Despair, now either a subversion or a toned down version with being creepy or a jerk instead of evil. Possibly invoked if he filed them himself to further mimic his prior bullies.
Fashionable Asymmetry: Keeps his sleeves and pant cuffs rolled up at different lengths. Wears a braid over his left ear while the right side looks like it's growing back from being partly shaved, along with a massive 'fin' over the top and growing out long on the other side and back. Even his earrings are like this, since his right one is based on a Philips head screw while his left is based on a slotted screw.
Freak Out: Does this a lot after Monokuma shows up.
Freaky Fashion, Mild Mind: Though apparently this is a recent development for him to try and be more popular since originally he had normal black hair and glasses instead of his pink hair and matching prescription contacts, which was more in line with his shy and nerdy personality.
Friendless Background: Thanks to being a bullied Shrinking Violet growing and he really wants to change that. He did have one friend for a while until that friend used him to cheat on a test, got caught doing so (though Kazuichi willingly took the brunt of the fallout from it), and abandoning him shortly after. While the abandonment may have been a result from the friend feeling too guilty about what happened it still left a pretty big impact on him, since it helped lead to his massive image change.
Green-Eyed Monster: His massive crush on Sonia leads to him being extremely jealous of the affection she shows Tanaka and his hamsters instead.
Heroic BSOD: Upon finding out that not only are he and his classmates the remnants of Ultimate Despair, but that if he pulls the plug as Naegi intends for them to do, Hajime Hinata will revert to the much less pleasant Izuru Kamukura.
Heterosexual Life-Partners: Latches onto Hinata, calling him his 'Soul Friend'. Includes a brief break-up when he blames Hinata for 'leading them' into Monokuma's trap and turns to Komaeda instead. Hilarity Ensues.
Hopeless Suitor: For Sonia, who develops feelings for Tanaka in the main game, and can end up with Hinata in Dangan Island.
In Chapter 2, the girls decide to have a girls-only "beach party", and Souda goes to quite a lot of trouble to figure out a way to get himself and Hinata invited to the party as well since the girls will all be in swimsuits. In Sonia's case he's disappointed, however, because she shows up in a wetsuit instead, and a wetsuit covers the entire body except the head. He's surprised for like two seconds before deciding he's totally okay with this.
Talking to him with the right item at a certain point in Chapter 3 will lead to him deciding to spy on Owari and Nidai with Hinata, believing, as a result of a suspiciously worded argument in front of a few others in Kuzuryuu's hospital room, that they're going to do that.That turns out to be... a massage.
Jerkass Façade: He was often bullied, and came away with the mistaken assumption that was what it meant to be strong.
Jerk with a Heart of Gold: On the jerk side, he's often jealous, harsh with classmates who don't necessarily deserve it, and somewhat creepy in his affections toward Sonia. On the heart of gold side, he's a nicer person than he seems at first glance, is one of the more empathetic ones when it comes to the deaths of their classmates, and has a few Pet the Dog moments.
Mr. Fixit: As a very talented mechanic he claims he can fix almost anything, and from what is seen in game he's right.
Nervous Wreck: After Monokuma hijacks the trip, if he's around you can pretty much bet there's gonna be screaming and crying.
Not So Different: Like Tanaka, he's trying to cope with his past loneliness by changing his image — in his case, trying to transition from Shrinking Violet to overly brash and outgoing.
Out of Focus: After establishing himself fairly early on as Hinata's Bromantic Foil, Souda's role starts to diminish around Nidai's first Heroic Sacrifice, only coming back in to supply comic relief or when he's needed. Notably, he's the only one of the survivors to have not lost someone close to them, reducing his role to cowering the whole final trial. Even his role as Hinata's Straight Man best friend gets slowly supplemented by Kuzuryuu. To gets to the point that, by Chapter 5, he hardly does anything and the fact he survives feels more like an afterthough.
Pet the Dog: After the fourth chapter's trial, he uses what's left of Mecha-Nidai (who was the victim of that chapter) to make a miniature Mecha-Nidai for Owari.
Red Herring: His primary purpose at times. He looks like a dangerous punk: He isn't, and then he seems like a pretty friendly non-threatening guy... Then his jealousy of Tanaka and his obsession with Sonia keep getting worse. Clearly this triangle is being played up for something: Nope, Sonia does try to get him killed once by accusing him during Nidai's case (which is ironically the one Gundam committed for unrelated reasons) but otherwise nothing comes of it.
Rose-Haired Sweetie: Played with, since as far as "cheery and optimistic or sweet and romantic" goes he does seem to fit at first to varying degrees... But its as much a forced façade as his dye job is and it shows. His "romantic" aspects lead to him becoming a Stalker with a Crush, his friendly behavior and positive attitude are prone to collapsing under stress, and his nice gestures tend to have ulterior motives or fall flat.
Sacrificial Lamb: Saionji teases Souda by calling him a 'background character' who's doomed to suffer an early death. His profile on the official Japanese site even implies the exact same thing. Subverted, because he's not! He doesn't kill anyone and he isn't executed, while Saionji herself gets killed in Chapter 3.
Sad Clown: He mentions in his final free time a lot of his positivity and more amusing antics are being forced to try and hide how scared he is.
Scary Teeth: His teeth are sharp and pointed like a shark's.
School Bullying Is Harmless: Nope. Many of his issues stem from being severely bullied, and internalizing the idea that acting like a bully was acceptable behavior/made you look 'stronger'.
Slasher Smile: Likely unintentional, but due to the above efforts to change his image. He is not a culprit however, and ultimately survives the entire ordeal.
Spear Counterpart: To the first game's Touko Fukawa. They share many of the same issues with bullying and isolation at their old schools, unsupportative parents, and developing stalkerish behavior towards a high-class blonde classmate that they idolize. Regardless of how said classmate rejects them, they continue to idolize and seek to please them, hoping to finally get their attention and into the relationship they long for. While Fukawa has the much nastier Syo, Souda instead openly adopted the negative behavior of those who mistreated him, mistaking that for strength.
Straight Man: He often plays a tsukkomi-type who accordingly reacts with shock to his classmates' surreal antics or when they start making absurd declarations.
Stalker with a Crush: His behavior toward Sonia eventually hits this point, according to her and much to her discomfort.
A master of the culinary arts, who prefers to be called a "Ultimate Chef" because he thinks it sounds more sophisticated. Hanamura has as much passion for romance as he does for his cooking, and spends most of his time on the island chasing skirts. He becomes the culprit of Chapter 1 after he figures out that Komaeda is plotting murder and tries to kill him first, accidentally killing Togami instead. He is found guilty and executed by being turned into a snack and "deep fried" in a volcano.
Absence of Evidence: This is what screws him over in Chapter 1's trial: Tsumiki trips and makes a fanservice pose while doing it, and he doesn't comment on it despite supposedly being in the room to see it. He of all people should be able to remember that, as Koizumi points out.
Adaptational Attractiveness: The manga preforms a downplayed example, as his features are noticeably relaxed, making him appear more normal next to the others.
And You Thought It Was a Game: At first, Hanamura refuses to believe that Monokuma's game is real. However, when he finds out that Komaeda is planning a murder, he hatches a plot of his own.
Anything That Moves: He may be a creep, but he's an equal-opportunity creep: he'll go after the guys with as much gusto as he does with the girls.
Bi the Way: When Nidai's the only one who responds to his offer to apply suntan lotion, his reaction is basically "[Beat] Sure, why not?"
Black Bead Eyes: Has these, in contrast to the other characters. They do get bigger if he's acting especially perverse and the only time we can see any of his sclera is when his eyes go wide when he gets mad and starts ranting in court.
Call Back: To the first murder in the original game. In both cases, the victim was not the original target of the murder, and the executions share some similarities in set-up (if not execution, thanks to a Bait and Switch).
Cruel and Unusual Death: His execution involves him being bound to a pole, pelted with missiles containing cooking oil and breadcrumbs by Monokuma, before being dragged off above an active volcano and dropped into it; deep-frying him alive.
Early-Bird Cameo: The Ultimate Cook was actually mentioned back in Dangan Ronpa Zero as a worker at the cafeteria Kamishiro meets Ryouko at. This actually leads to a subtle Continuity Nod, as Ryouko mentioned that its rumoured the food served had drugs in it. Hanamura's final Free Time has him giving Hinata drugged food.
Expy: Of Yuuto Kamishiro from Dangan Ronpa Zero, sharing the same basic design concept, as well as their status of relentless perverts and tendency to fake details about themselves. There's even official art of the two standing next to each other in a group shot, eyeing Tsumiki. Word of God confirms this as intentional, as Hanamura is the series' second attempt at the same archetype (with Kamishiro being considered a failure).
Gratuitous English: Along with Gratuitous French. He even uses gratuitous English during the final Machine Talk Battle; Hinata has to shoot down arguments like "NONSENSE!" to break Hanamura.
Hormone-Addled Teenager: Unlike most examples of this trope, however, he gets hormone-addled over pretty much anybody, girl or boy.
Ill Girl: Not Hanamura himself, but his mother, who has worked herself to the point of illness and exhaustion to keep the Hanamura restaurant afloat. Teruteru worries that she'll keep overworking herself in his absence. Her fate is currently unknown, though the fact that he was part of SHSL Despair casts very sinister implications...
Implausible Deniability: He's the most fervently in denial about the mutual killing game, since he's the most desperate to believe that it's not true.
Inelegant Blubbering: His reaction to Hinata managing to figure out that he's the one who murdered Togami.
Hanamura: Hoh hoh... I may be a pervert, but I'm the lovable type of pervert that people just can’t bring themselves to hate!
Manslaughter Provocation: He tries to claim this because he knew that Komaeda was planning murder. However, the other characters immediately point out that he could have told anyone else when he found out, and worked with everyone to neutralise Komaeda in a non-lethal manner.
Momma's Boy: It's even stated so in his profile. After being revealed as Chapter 1's culprit, he briefly has a flashback that reveals how much he worries about his mother's health, and he screams for her just before Monokuma starts the execution.
Nosebleed: A fairly common expression, combined with a minor Art Shift where he gets bigger, determined eyes. Like the rest of the blood in the game, his nosebleeds are pink.
Ooh, Me Accent's Slipping: When put on the spot, his voice slips into a "rural" (more of a Cajun accent in the official translation) dialect so impenetrable that Monomi needs to translate for him.
Pet the Dog: He's presented as a pervert who keeps hitting on people, and he's Chapter 1's murderer when his plan goes wrong and he ends up stabbing Togami instead of Komaeda. But just before he's executed, we get treated to a flashback of him worrying over his beloved mother (who, appearance-wise, he strongly resembles). He really seems to love and appreciate her, which makes him more sympathetic when he screams out to her just before Monokuma executes him.
Repetitive Name: With the term "Teru", which when repeated means "shining". (like a "Teruteru bozu" weather charm, named for their bald head)
Strong Family Resemblance: We get a flashback of Hanamura with his mother. He looks almost exactly like her, because she happens to be cutely chubby and has an identical facial structure.
Supreme Chef: He's a Ultimate Cook. Of course, he prefers to be called a Chef. He prefers to be called a "Chef" because he's trying to pretend he grew up in a sophisticated urban neighborhood, in order to hide the fact that he actually grew up in a rural area.
Sympathetic Murderer: Since the person he was really trying to kill was already planning to murder someone else and he only wants to go home to find out if his ill mother is okay.
The Unintelligible: When he's particularly riled up, his speech becomes impossible to understand for everyone except Monomi.
Unwitting Pawn: Turns out his attempt to kill Komaeda was what Komaeda was banking on. The only reason Togami got killed instead was because Togami pushed Komaeda out of the way.
Villainous Breakdown: As he becomes clearer he was responsible for the first murder, he becomes so agitated his accent starts coming through stronger and stronger, to the point only Monomi can understand him. Lampshaded by Komaeda.
What the Hell Is That Accent?: When he gets upset, his accent becomes so thick he's all but unintelligible. It's somewhat easier to understand in the official English localization, though. In the translation, It's an exaggerated Cajun accent, similar to the late chef Justin Wilson (known for having a cooking show on PBS).
A legendary coach with a knack for taking terrible teams and turning them into champions. Though he looks more like an athlete than a coach, Nidai burns with intensity and passion, and has a massive voice to match his massive stature. He is gravely wounded after protecting Owari from an attack by Monokuma, and remade into a cyborg. However, his new metal body does not prevent him from becoming the victim of Chapter 4 when he is killed by Tanaka in their death pact.
Antiquated Linguistics: In the Japanese version he speaks using an archaic dialect, and like a professor on top of that.
Battle Aura: Always has one, including lightning from his eyes. Given his SHSL title, it might symbolize his passion. Interestingly, when Nidai is turned into a cyborg, he stops having a battle aura for every single sprite, he only has it for three sprites (and two of them are subdued compared to before), and no lightning comes from his eyes.
Cybernetics Eat Your Soul: Tanaka mentions that cyborg Nidai had a killing intent when he went to shut him off (so that he could set up his murder). He might have been right, as Nidai's Battle Aura is often gone from his sprites as a cyborg and seeing that the one who gave him his robotic form was Monokuma...
Protects Owari without any reason to believe he'd survive being hit by a bazooka shot.
And pulls this again when he and Tanaka make a mutual sacrifice pact so that the others wouldn't starve to death.
Hidden Depths: An Easter Egg reveals that he's also a Ultimate Masseuse. Furthermore, part of the reason he became a sports manager was to emulate his friend Daisuke, who died before his own team could reach victory.
Ill Boy: His free time events reveal that he was born with a heart condition that kept him out of school for long periods of time.
In-Series Nickname: After he gets turned into a robot, some call him "Mecha-Nidai" in the Japanese version, and "Mechamaru" in the English version.
Large Ham: He's larger than life in almost every possible way. One of his arguments in a Nonstop Debate is several times the size of all the other text.
Love Freak: Well, "Spirit" freak. Even BULLETS CAN'T PIERCE SPIRIT!
Made of Iron: Once he's turned into a cyborg, he can withstand Monokuma's bazooka. However, this doesn't help him avoid being killed in Chapter 4 by Tanaka.
It should be noted that he took a bazooka blast from Monokuma in his human form as well, and not only wasn't reduced to Ludicrous Gibs, but managed to hold on long enough to be turned into a cyborg.
Meaningful Name: "Ni" is Japanese for "two". His stats as listed in his profile include a lot of 2s, and he starts with a 2 in the Gathering stat in Dangan Island. Also, he has two bodies over the course of the main story, one human and one robot, both of which are killed.(mini mecha!Nidai doesn't count since it was a mostly mindless toy)
Potty Failure: Played for laughs in Chapter 1 during Togami's big party. Nidai needs to use the restroom, but cannot because Pekoyama, is already inside, suffering from stomach problems. Then, given his Hot Blooded tendencies, he apparently decides that his inability to "hold it" is something he needs to SHOUUUUUUT ABOOOOOOOUUT!
Saying Too Much: In Chapter 2, he insists that the traitor is tied up and can't move at the moment, implicating himself as the one who kidnapped and tied up Komaeda (who isn't the traitor, though). He then asks Souda what to do, implicating Souda as his accomplice.
Ship Tease: He starts "training" Akane as a pet project, and his talents as an Ultimate Masseuse lead to a number of highly suspicious conversations between them. When he perishes, both times, Akane is devastated with grief, despite her unwillingness to admit it to anyone, even herself.
Taking the Bullet: For Owari, once she tries to attack Monokuma in Chapter 3. This causes him to be hospitalized and eventually turned into a cyborg, though this helps avert the trope when he tries it again in Chapter 4.
Toilet Humor: He often declares that some great life rules to follow are to "EAT WELL, AND SHIT WELL!" with many characters being mystified at why he gets so fired up about his bodily functions. Additionally, around the time the first murder occurs, he desperately has to go to the bathroom, but Pekoyama is occupying it. NintendoCapriSun would be proud. When he and Hinata briefly team up in Chapter 4, Mechamaru always pauses in front of bathrooms to stare unhappily and also mentions that the inability to poop is one of the few things he regrets about his robotic condition.
Underdogs Never Lose: Nidai causes this trope to happen, which is why he got the title of Ultimate Team Manager. Specifically, in his backstory he's frequently taken teams of terrible players and used his superior management skills to take them to national tournaments.
We Can Rebuild Him: At one point, upon being severely injured, he's upgraded into a cyborg. Unfortunately it doesn't help him avoid being murdered in Chapter 4, because the culprit, Tanaka, uses one of his hamsters to press a button on Nidai to knock him out in order to set up his murder. Souda eventually uses parts of cyborg Nidai to build a miniature robot version of Nidai with his voice, to cheer up Owari.
After Monokuma 'fixes' him, he reacts very poorly whenever the others treat him differently over it. Averted in that what Tanaka does to him is still considered murder, even if it was in a death pact to save the others.
However, the trope is also used metafictionally. When the other students find Nidai's body, not only is his head bashed in and separated from his neck, but one arm has come off at the shoulder and he's lost the lower half of his leg. There is no way they would've been able to show this if he was still a flesh-and-blood human.
The babyfaced successor to the infamous Kuzuryu family, the largest criminal enterprise in Japan. Kuzuryu's small stature and youthful looks hide a powerful temper and a large chip on his shoulder, and he has no interest in making friends with his classmates. In Chapter 2, he discovers that Koizumi was involved in the cover-up of his sister's murder, and Pekoyama (his loyal hit-woman/bodyguard) kills her on his behalf. However, after Pekoyama is voted guilty he is unable to claim responsibility as the "true culprit" because it would confirm Pekoyama's (incorrect) assumption that she was nothing but a tool to him. He tries to save Pekoyama during her execution and loses an eye for his efforts. Between the loss of his eye and Pekoyama, this humbles him greatly and he goes on to survive the final trial.
The Atoner: From Chapter 3 onwards. In his fourth Free Time event, he resolves to help the group survive and get out so that the deaths he caused will not be meaningless, and resolves to visit a cemetery for Koizumi, as well as his sister and Pekoyama, after he gets out.
Don't bring up how cute he looks if you know what's good for you.
He does not take what happens in Chapter 2 well. Specifically, the implication that his sister may have been killed, and that Koizumi covered up for the murderer. But what really sets him off is when Koizumi chastises him for killing Satou, saying that he had no right to take revenge in that way (despite that fact that "an eye for an eye" is the norm in Kuzuryuu's mafia family).
Blond Guys Are Evil: Ultimately subverted. He starts off seemingly antagonistic, but mellows out after Chapter 3.
Break the Haughty: The aftermath of Chapter 2's trial. He learned his sister is probably dead, which he didn't even remember thanks to having his memories erased, and his revenge plays right into Monokuma's paws, leading to losing Pekoyama and knowing it's completely his fault.
Cynicism Catalyst: The murder of his sister, and Koizumi covering for the murderer, which leads to him seeking revenge...
Dare to Be Badass: Does this to himself in his ending in "Dangan Island", insisting that he won't run from his weakness or from being compared to his sister, and he'll definitely continue the gangster line and reap the earth with his own hands.
Does Not Like Spam: The game states that he hates milk. This is because of the notion that milk helps you grow taller, and he was never able to drink it because he is lactose intolerant, combined with the fact that he hates how short he is. Even the very mention of the word milk pisses him off.
Of original-game-era Byakuya Togami, both being blonde-haired, ruthless and socially powerful. They also both immediately declare I'm Not Here to Make Friends and refuse to obey the group dynamic (e.g. Togami disobeying the "Night Time" rule the students had imposed upon themselves; Kuzuryu refusing to go to the "mandatory" party). Like Togami, Kuzuryu is also one of the final survivors of the game. However, unlike him, Kuzuryu allows his emotions to get the better of him at one point, with disastrous consequences. Interestingly, his relationship with Pekoyama plays near diametric opposite to Togami and Fukawa's relationship.
A guy who is introduced as an antagonistic jerk and turns out to have deep issues stemming from his love for his childhood friend? Sounds a bit like Yasuke Matsuda, doesn't it?
Eyepatch of Power: He starts wearing an eyepatch following the eye injury he sustained while trying to stop Pekoyama's execution. It's debatable whether it makes him more "badass", though he was the first student in the series to attempt to interfere with an execution in progress.
When Kuzuryu forces his way through the samurai Pekoyama is fighting during her execution in Chapter 2, Pekoyama ends up slicing him in the eye.
It's speculated that, based on the hairstyle and circumstances, the person transplanting Enoshima's eye into himself was Kuzuryuu, since the eye Kuzuryuu replaced is the same as the one he lost in the game. This is unconfirmed, however.
Foreshadowing: During the first trial, he steps in and makes an argument when Pekoyama is accused of murder, despite originally having planned on not getting involved, a strong hint towards the revelation of their past.
Heel-Face Turn: After Chapter 2's trial he starts opening up more and tries to be more helpful and friendly to the group.
Heroic BSOD: Upon finding out that not only are he and his classmates the remnants of Ultimate Despair, but that if he pulls the plug as Naegi intends for them to do, Hajime Hinata will revert to the much less pleasant Izuru Kamukura. Unlike the others, however, this is more due to his conflict over whether he wants to meet Pekoyama again.
I'm Not Here to Make Friends: He is even worse about it than Togami was in the first game, to the point that even Togami himself scolds him about this.
Jerk Ass: In the first two chapters, he is quite abrasive, casually threatens people with violence and claims to be willing to kill any of the others. He grows out of this.
Jerk with a Heart of Gold: Falls squarely into this after Chapter 3. He's still hot-tempered and fairly rude, but he's also willing to cooperate with the others.
The Lancer: After Pekoyama's execution, Kuzuryuu becomes completely devoted to trying to help everyone survive on the island and is generally the first to volunteer to help Hinata. He's also notable for being the only character in the series that might have gotten away with being the culprit but refused out of the sake of principle.
Love Hurts: To Pekoyama, big time. Enoshima even mocks him over it in the final trial.
OOC Is Serious Business: Immediately before his attempt at seppuku, he greets the students in an oddly formal manner. Hinata mentally notes that he doesn't usually say hi to people.
Odd Friendship: Strikes up one with Owari, of all people, in Chapter 4, bonding over how they are still alive because others sacrificed themselves.
Pet the Dog: In Chapter 4, he talks with Owari, who feels guilty over Nidai jumping in to save her and ending up as a cyborg, mentioning how Pekoyama protected him in her final moments, and helping her work through her guilt.
Pyrrhic Villainy: Avenges the coverup of his sister's murder... at the cost of Pekoyama's life.
Spanner in the Works: For the fourth case. His decision to stay in the lounge after seeing Nidai head downstairs prevents Tanaka from heading back to his room and pretending to be asleep, which would be the perfect alibi. In turn, this eventually leads to Tanaka being correctly pinned as Nidai's murderer.
Taking the Heat: He offers to do this for Pekoyama after she kills Koizumi, and it's implied that his attempts to deflect suspicion away from Pekoyama, such as facing Hinata in the P.T.A. battle, are done with the goal of preventing her from being convicted.
Tsundere: A male version towards the rest of the group. It's painfully clear that he wants to be involved in the group activities, but furiously denies it because he has his "hardass mob boss" image to maintain. Nanami makes this observation about him when asked about the time she saw him walking by the party, and how he responded to her questions by claiming he was just taking a walk.
Villainous Breakdown: When Pekoyama reveals her intention to help him graduate, and that it hinges on him calling her a tool, the strain of the whole chapter's events makes him break down, declaring that he never needed or wanted her as a tool — all he ever wanted was her.
Walking Spoiler: A variation. Kuzuryu's Free Time Events are locked from player accesses until he's released from the hospital in Chapter 3. As a result, its difficult to talk about him without giving away the ending of the second trial; namely that he, a suspect for the murder, survives, and his Free Time events are full of spoilers for the outcome of the trial and his resulting Character Development.
A superb athlete with an unusually large bust for a high-school girl. She has a remarkable talent for inventing her own moves, but tends to under-perform when she's in a bad mood. A brash and argumentative girl with a love of food and fighting, Owari isn't quite the sharpest thinker on the island. She survives the final trial and escapes to the real world with the other survivors.
Dark and Troubled Past: Grew up in rough circumstances and had to deal with perverts throughout her life, such as being expected to work without wearing panties at her waitressing job (though she seems rather oblivious to how perverted her admirers were). The reason she has such trouble remembering names is she saw people dying around her so often she didn't see much point in getting to know them better. Owari's family life wasn't any better either; she had 7 siblings and an unemployed father and had to constantly work part time to support them until she started doing gymnastics. She also states that who her mom or dad were tended to "change", along with an increase in the number of siblings. Take that as you will.
Dumb Muscle: Physically, she's very strong and athletic. Mentally, not so much.
Expy: Seems to be one of Asahina, from the first game. She also seems to take some traits from Oogami as well. In addition, her friendship with Nidai is very similiar to Asahina's relationship with Oogami, though Nidai is not The Mole in this case. Right down to surviving all the cases, since she's one of the few people who is never either murdered or executed as a murderer, just like Asahina was. Her love for food in general can be seen in a similar light to Asahina's love for donuts and food in general. Asahina takes Fukawa's motivation to pig out as somewhat of a challenge saying they should eat all they can, which is something that Owari would most likely say. On top of all that, her official artwork's pose (seen above) is nearly identical to Oogami's and her initials A.O. are the same as Asahina and Oogami's, to help drive home the idea that this Expy was on purpose. Plus, she takes a bit after the third athlete in the first game, Kuwata, as she's a "natural" who dislikes hard work and cares about her talent as a gymnast mainly for what it can get her.
Heroic BSOD: After Nidai takes a bullet for her, she begins to lose it and sinks into a deep depression. Subverted in that the real cause of her shift in personality is a despair disease released by Monokuma.
Also, upon finding out that not only are she and her the remnants of Ultimate Despair, but that if she pulls the plug as Naegi intends for them to do, Hajime Hinata will revert to the much less pleasant Izuru Kamukura.
Huge Schoolgirl: At 176 cm (5' 9") she is very tall for her age and nationality.
Indy Ploy: Her preferred method of doing gymnastics is just to go out there and make up a routine on the spot. She is actually incredibly talented at coming up with innovative new moves (hence her Super High-School Level Talent) but the main reason she does this is because she hates the hard work and tedium that would come with composing and practising a routine beforehand.
Innocent Fanservice Girl/Shameless Fanservice Girl: Treads the line: she doesn't understand why most of the others think it's a bad idea for her to go swimming without a suit, nor does she care. This extends to the attention she got from perverted admirers as well.
Irony: Most gymnast are small and petite, she is not.
Is It Something You Eat?: During Chapter 1's trial, at one point Owari asks what "aspersion" is and whether or not it's something you eat. This trope annoys Saionji enough for her to suggest Owari should try also eating asbestos.
It's Personal/I Owe You My Life: She vows to find Nidai's murderer, as he had saved her. Despite that, she's relatively understanding once she realizes that Tanaka killed Nidai because he wasn't content with everyone starving to death.
Le Parkour: She mentions that she did quite a bit of it when she was on the streets.
Massive Numbered Siblings: One of her Free Time events reveals that she has 7 siblings and that she had to work hard to support them because her father was unemployed.
Mood-Swinger: She can bounce between bored, to happy, to angry, and to happy again very quickly.
The Nose Knows: In Chapter 1, this is how she discovers Togami's stabbed-to-death body underneath the table, since she was able to smell Togami's spilled blood. At the beginning of the next chapter, she's the first person to notice how bad Saionji smells.
Only in It for the Money: If Owari is a Ultimate Gymnast, why does she like battles so much? During a Free Time event it turns out it's because she only became a gymnast in order to win lots of money from competitions by setting records, and the Ultimate part is because even though she only does gymnastics for the money, she also happens to be really good at it.
Ship Tease: Lots of it with Nekomaru, who take her under his wing as a manager and quickly becomes her closest friend on the island. Both times he dies deeply affect her emotionally, despite her tough outer shell, and she ends up carrying around "Minimaru" as a memento of him for the rest of the game.
Slasher Smile: When she gets a Battle Aura as described above, she also has this kind of smile.
A royal princess from the small European country of Novoselic, who has come to Hope's Peak Academy as an exchange student. Sonia has all the beauty and grace that her title implies. However, she can be a bit naive and overly trusting, and her grasp of the native language is a bit... tenuous. She survives the final trial and escapes into the real world with the other survivors.
Break the Cutie: Tanaka being found as the culprit of Chapter 4 causes her to break into a fit of tears. She also takes Nanami turning out to be the traitor quite hard, even going so far as to make arguments suggesting that she herself is suspicious.
Cuteness Proximity: Starts cooing over Tanaka's Four Dark Deva Lords the moment she sees them.
Crazy Cultural Comparison: Once in awhile she'll do this when talking to Hinata, such as getting a little mad at him for not arriving to their meeting spot 13 minutes early because that is the expected time in Novoselic, or questioning why he doesn't know how to handle a tank because in Novoselic you start learning how to use such things in elementary school.
Ditzy Genius: She's able to make smart deductions when the time calls for it, is capable of complex political analysis, and has admitted to being able to speak and read over 30 different languages. The ditz part is more or less due to the language barrier, and her limited knowledge of Japanese culture, or society, in general.
Everything's Better with Princesses: Her talent, and it shows... Well, considering she was a SHSL Despair she was actually subversion only to become a double subversion by the game's end.
Heroic BSOD: Upon finding out that not only are she and her classmates the remnants of Ultimate Despair, but that if she pulls the plug as Naegi intends for them to do, Hajime Hinata will revert to the much less pleasant Izuru Kamukura. In her case, she's particularly bothered by the idea that if they lose all their memories from the game, it will negate the meaning of everything they've done so far.
Hidden Depths: Early in the game, she proves she is capable of complex political analysis when she gives a speech about how power and wealth gradually lead to the ruin of civilizations, and when she wants someone to take her seriously she strikes a dramatic pose and speaks with an "aura" of absolute authority. She also has no intention of either killing anyone or meekly being killed. She gets her wish: by the end of the game she hasn't killed anyone and no one has killed her.
I Just Want to Be Normal: She is expected to put up the front of a strong and infallible princess back in her home country, and though she's more than willing to do that for the sake of her countrymen, she admits that it would be nice to experience life as a normal high school girl and be treated as one.
Lethal Chef: What a bit of bonus art in the manga shows her to be.
Meat-O-Vision: Comes down with a bad case of Dessert-O-Vision when Monokuma is starving everyone to death in the funhouse; she starts hallucinating that the other students are delicious desserts and asks them politely if she can eat them.
Micro Monarchy: Her native land of Novoselic appears to be one of these.
Never Speak Ill of the Dead: Sonia is one of the students who shows great respect to those who have died, and doesn't like it when their deaths are disregarded or they are insulted. A primary example of this is in Chapter 5 when she becomes upset with Komaeda for insulting Tanaka and Togami, and demands he apologize.
Nice Girl: She's polite and charming and gets along well with everyone, and she doesn't have a mean bone in her body. Which is probably why she's one of the few students who survives the entire game, since she provokes no one into killing her and she never has any desire to kill anyone so she isn't executed.
Nice Job Breaking It, Hero: In Chapter 3, Sonia suggests that Saionji use the full-length mirror at the back of the stage to help her put her kimono on. Unfortunately, unbeknownst to Sonia, a murderer was waiting at the back of the stage and Saionji dies because of it.
Nightmare Fetishist: According to her profile she enjoys the occult, which is rather unexpected of a prim and proper princess. She admits in chapter 1's trial that she watches Friday the 13th with a gleam in her eye, and also has an avid admiration for serial killers, to the extent that when she talks about Genocider Syo she calls him splendid and that he represents the hope of the young generation.
Omniglot: She can read, write and speak in over 30 different languages.
Serious Business: In Sonia's first "Free Time" event, Hinata learns that Japanese "TV dramas" are this to her. This seems to be the case for her whole country: at one point, Hinata learns that a popular Japanese Magical Girl anime for kids got a rating of 90% (that's 90% of the entirepopulation) in Sonia's country.
Sheltered Aristocrat: Seems like this at first, but as time goes on there are more indications that she's smarter than she lets on.
Shout-Out: A walking Homage to the band Nirvana. Sonia's home country is named after the bassist, Krist Novoselic, and her last name is also the title of the band's second album, Nevermind.
Sophisticated as Hell: Sonia talks using very formal and polite language, as expected of a princess... except in addition to that, she also sometimes peppers her speech with informal slang such as "hella" or "you betcha", as well as lots of references to outdated popular culture.
Wacky Marriage Proposal: In the alternate universe mini-game scenario "Dangan Island," if you get Sonia's ending Hinata and she make plans to get married according to the customs of her people, by fighting and defeating a creature called a Makango. Which is the marriage custom for normal people in Sonia's culture, but if it's Sonia specifically, then since she's a princess it has to be a golden Makango on top of that.
Was It All a Lie?: Asks this of Nanami after Nanami is revealed as The Mole, wondering if all the time they spent together meant nothing, but soon concludes that Nanami did not betray them.
The Woman Wearing the Queenly Mask: Not a ruler yet, but as a member of the royal family she's used to hiding her fears. In Free Time she reveals that she's already been kidnapped twice, and she eventually breaks down crying in front of Hinata.
You Remind Me of X: In her free time events and Dangan Island ending, it turns out that because Hinata is wearing a white shirt and has his hair done in an antenna, he fits the description of a legendary hero in Sonia's culture, which is why Sonia wants the two of them to get married.
A rising star in the art of traditional Japanese dancing. Saionji is popular for her youthful appearance and grace, but conceals an abrasive personality and a nasty mean streak. She is the first victim of Chapter 3, after she walks in on Tsumiki staging a murder and is silenced by having her throat slit.
Ambiguously Bi: Even if she can obtain a romantic ending with Hinata in Dangan Island, she also acts extremely clingy and affectionate around Koizumi, to the point that she outright drags Koizumi away to have a shower with her. The Les Yay implications aren't lost on Mioda.
Blush Sticker: Like Kuzuryuu's to make her appear more child-like and cutesy. They suit her about as much as they do him when she starts showing her true colors.
Bratty Half-Pint: Even though she's just as old as the rest of the cast, she certainly appears this way physically, and her attitude more than qualifies her. In reality, Saionji only physically looks like a child because that's what she looked like when she entered the academy.
The Bully: Snipes at everyone, but particularly Tsumiki and Souda, who also tend to react the most.
Crocodile Tears: She has a tendency to fake crying at times, but actually genuinely cries other times, making it hard to tell which is which. To make things even more confusing, in her final free time event, she openly claims to have been manipulating Hinata by crying, but Hinata says there are still tears in her eyes.
Daddy's Girl: Her father is the only close relative she has whom she doesn't hate with a passion, because he married into her clan.
Due to the Dead: In Chapter 3 Saionji takes the time to build a memorial in the dining hall for Koizumi after she is murdered, such as putting all the pictures she took up on a board so everyone can see them and placing rows of candles on an altar. Though the memorial doesn't look very...Inviting.
Establishing Character Moment: She's introduced as a seemingly cute little girl...who's casually crushing ants for fun, which gives you some idea of the contrast between her appearance and her personality.
Expressive Hair: The bottoms of her pigtails have a tendency to morph in her different expressions.
Expy: Shares many similarities with both Celeste and Junko from Dangan Ronpa, in terms of both design (Mega Twin Tails and very specific fashion choices based around a culture/sub-culture) and personality (Manipulative and cruel with a heavy emphasize on using their appearance to affect how others view them for their own gain). This was likely meant to be a Red Herring to encourage the player to (further) suspect her of being a future killer or having a connection to Enoshima.
Her free-time events reveal she is the heir of her family who has suffered a lot for her talents (Due to jealousy from other family members) and has made other members of said family suffer for her own sake (Her step-father in particular), not unlike Togami's history with his family's "tradition" and his older siblings. She also has a similar mind-set to him at times, specifically referring to herself as a "perfect person", treating everyone around her as servants to use or misuse as she pleases, and being Not So Different with Monokuma. Like the above this also seems very intentional since, as she was meant to be a survivor instead of Kuzuryu, this would have made her the Togami parallel of the surviving cast just as he ended up being in the final product.
The Fake Cutie: She uses her cute appearance and childish mannerisms to gain popularity as a traditional Japanese dancer, but her personality is anything but cute.
Freudian Excuse: Though its factuality is disputable (see Unreliable Expositor below), the backstory she reveals helps explain some of her bullying ways. Lots of literature on bullying talks about how the bully is trying to recapture a sense of power and agency they lost from being mistreated by mistreating others.
Good Old Ways: Going with her preferred outfit and talent, her Free Time events reveal that she has a lot of respect for traditional Japanese customs and feels that they need to be kept alive. Of course, this is followed by her expressing contempt for those who like anything western.
Green-Eyed Monster: One of her free times implies she's jealous of Sonia, and she tries to recruit Hinata into some Revenge by Proxy by targeting Souda first. When he refuses, she just thinks he wants to cut straight to the 'main event' and go after Sonia directly.
Heel Face Door Slam: Just as it seems she may be finally getting some much needed positive character development she winds up dead.
Hypocritical Humor: She tells Tsumiki that she has no right to privacy when she complains about being "A-ko" in Twilight Syndrome, but when it turns out that Saionji is "B-ko", a character who used the insult Saionji just made against Tsumiki, she says the game is "taking way too much creative liberty."
Kids Are Cruel: Subverted, she looks like a kid and her introduction features her squishing ants just because, but she is actually the same age as everyone else. This makes her behavior come off as quite unsettling.
Kimono Is Traditional: Since she's a traditional dancer. However, it's later revealed that she doesn't know how to tie her obi by herself.
Jerkass: To the point she outright bullies Souda and Tsumiki, who are not only almost twice her size but both have had very bad experiences with bullying in the past.
Jerkass Has a Point: After the first murder occurs, she's one of the few to keep her head on straight, and keeps bluntly reminding everyone that no matter how upset they are or how much they're freaking out, they need to investigate and solve the case if they want to live.
Laser-Guided Karma: The girl (Tsumiki) who was always the target of Saionji's cruel bullying ends up being the one who murders her. And yet, it's averted by the fact that her treatment of Tsumiki had nothing to do with her murder.
Mega Twintails: Held up with little kitty heads to go with her child-like appearance.
Meta Guy: On rare occasions. She refers to Tsumiki's clumsy tripping as "fanservice", refers to Souda as the sort of person who's one of the first to die in "kill 'em all" scenarios, and at the party after Hinata reassures Saionji that Togami physically searched everyone, not just her, Saionji bets that maybe Togami was "extra sticky" with her since "someone like her" is in "high demand" (she doesn't specify what she means, but it's obviously a reference to her "cute girl appearance").
The Nicknamer: Prefers degrading and insulting nicknames, like calling Togami "Mr. Porkfeet" or Tsumiki "Dirty Bitch".
No Sympathy: The day after the first trial, she halfheartedly concedes that Togami's death was "sad," but then says that Hanamura, as a murderer, was "human waste," that she enjoyed his execution and that she wishes they could have spat on his body. Koizumi is the only dead student she actually mourns for.
Not Helping Your Case: In the second trial, she spends much of the early discussion of the actual murder drawing suspicion to herself, such as falsely claiming that she never went to the beach house.
Not So Different: Much like Monokuma, she thinks that the executions just 'even out' the score and are what the murderers deserve.
Older Than She Looks: Yes, she really is just as old as the other students. Subverted, however, when it turns out that she only looks so young in the game because that's what she looked like when she first entered the academy. Her real appearance is more in line with her age.
Pet the Dog: Koizumi is the only other student who Saionji seems to have any respect for, calling her "big sis" and acting very affectionate and clingy around her.
This Is Unforgivable: She absolutely refuses to forgive those that murder others, but especially Kuzuryuu since he was involved in a murder that planned to pin the blame on her. However, she softens after Kuzuryuu attempts suicide as penance, a sign (Hinata notes) that she is attempting to change for the better.
Tempting Fate: She teases Soda by calling him a 'background character' who's doomed to suffer an early death. She is killed in Chapter 3, while Souda is one of the survivors.
Token Mini-Moe: In appearance only, since she's the same age as the rest of the cast and the "moe" aspect is deliberate on her part.
Tsundere: Extreme type A example to Hinata, during Free Time events and Dangan Island.
Unreliable Expositor: Exploits this by telling Hinata that she's been bullied and targeted by her own family out of jealousy for her position, that her father went mad trying to protect her, and that she's been raised by her grandmother without having any chance to even see her parents... before laughing and leading him to think she was lying about all or part of it. That said, she shows visible anger when Hinata calls her by her last name (since she hates her family that much) and genuinely starts tearing up when mentioning her father, implying that at least some of it wasn't a lie.
Wardrobe Malfunction: Sort of. Saionji's been wearing the same traditional Japanese dancing clothes for a long time, because the clothing is apparently so complicated she can't tie her obi by herself (which means if she were to take the clothing off she wouldn't be able to put it back on), which means she hasn't bathed in a while. In Chapter 2, Koizumi agrees to help Saionji take her obi off and on. This ends up contributing to her death, as in Chapter 3, having trouble tying it now that Koizumi's dead, she takes Sonia's suggestion to use the full-length mirror at the back of the stage, where Tsumiki was setting up the murder of Mioda.
A promising young photographer who has won many awards for her portraits. Though she can be a bit critical at times, Koizumi is one of the more sensible and level-headed students on the island. She is the victim of Chapter 2, bludgeoned to death by Pekoyama on behalf of Kuzuryuu.
Cool Big Sis: While they're the same age, she acts as one toward Saionji such as helping her with her clothes and taking baths with her. She is also one of the very few students that Saionji doesn't insult and the one who she seems to genuinely adore.
Declaration of Protection: Inverted; she's the one who outright demands that Hinata promise to protect her. Not that it does any good, since she is murdered in Chapter 2.
Destroy the Evidence: She's girl "D" in Monokuma's game, the "motive" he provided for the second chapter, whose photos could prove that girl "E" (named Satou) murdered another girl. Rather than tell the police, she cleaned up the evidence that could have pointed to Satou and confronted her directly. She decides to not turn her in upon listening to her (Satou killed the girl because she bullied Koizumi). What does this have to do with the motive? The girl who Satou killed is Kuzuryuu's sister, and because Kuzuryuu completed the game first, he received the photos that Koizumi took, and upon seeing a photo of his dead sister (and possibly piecing together who "D" was in the game) he got angry and sent the photos to Koizumi, who felt guilty once she saw them. This is why Koizumi is murdered in Chapter 2: Pekoyama kills her for Kuzuryuu's sake.
Fiery Redhead: She can get a bit pushy and argumentative when people don't live up to her standards.
First Name Basis: She tends to call the other female students by their first name and "-chan", possibly because she tends to get along with them better than the male students.
Jerkass: A lowkey version. She can be pretty mean towards the boys, especially Hinata and Souda.
Jerk with a Heart of Gold: She is much more often this, though, being kind to Saionji when no one else is, is shown to be one of the most affected by Togami's death, contributes greatly to the investigation, and greatly believes that revenge is wrong and second-changes are important.
Like Mother Like Daughter: In her free time events and her Dangan Island ending, Hinata learns her mother was also a great photographer, and she briefly wonders whether or not she can become like her mother just by taking photos of whatever she likes. Is taking photos all she can do...? Hinata cheers her up by pointing out Koizumi has lots of other good points.
Morality Pet: In a sense, she's Saionji's; while Saionji isn't a villain, she's still a sadistic bully to everyone else but Koizumi, who she's very clingy and affectionate towards.
Only Sane Woman: Tends to react to situations in a more predictable manner, and is the only student without an obvious quirk.
Ordinary High-School Student: Well, not really of course since she's an Ultimate Photographer, but she is this trope in spirit, if not on the letter. Notably, her pose in her official art is a lot more casual and normal compared to the rest.
She can be a bit abrupt and somewhat critical, but she's capable of being nice: when she finds out Saionji isn't taking baths because she can't re-tie her obi properly, Koizumi offers to help.
Despite not getting along with Hanamura and being horrified and angry to learn about his decision to commit murder, she, reflecting upon what he said before his death, sympathizes with his desire to see his mother.
Tap on the Head: A lethal example of this trope, as she dies from being bashed in the head with a baseball bat.
Tsundere: Harshly critical towards men in general, and keeps upbraiding people like Hinata and Souda for not acting the way she feels they should. Despite this, shows a softer side at times. For example, when Togami turns up dead in Chapter 1, Koizumi's one of the first students to get upset about it, and she's one of the most upset, in fact.
True Art Is Angsty: invoked Discussed, as she worries that her pictures of happy subjects don't have as much merit as her mother's war photography.
She angrily asks Hanamura why he felt he needed to try to kill Komaeda in order to stop his murder plot.
When meeting with Kuzuryuu, she asks him if he killed Satou, before telling him that "Revenge... is just wrong!" This leads to her death, as Kuzuryuu gets angry, and goes for the bat to try to kill her, but Pekoyama kills her first, believing she's doing his bidding.
A talented nurse who can treat any injury. Painfully shy and clumsy, Tsumiki can hardly hold a conversation without bursting into tears and apologizing. She is the culprit of Chapter 3, having been infected by the Despair Disease, which caused her to regain some of her lost memories (as a part of Ultimate Despair) and completely lose her mind. She goes on to murder Mioda and Saionji, and is executed by Monokuma after being found guilty, shot into space on a giant arm injected with rocket fuel.
Accomplice by Inaction: Accuses the other students of this before her execution, stating that it was mostly their fault she became what she was, because no one would come to her aid when she was ridiculed and humiliated by her peers.
Bandage Babe: Possibly due to her clumsiness or her history of being bullied.
Beneath Suspicion: When Hinata accuses her of being the murderer of Chapter 3, the others find it unlikely that she could have done it- both in that she doesn't seem to have it in her to do something so terrible, and that she doesn't seem capable of it. Her initial strategy is to be even more self-deprecating than usual.
Tanaka: Hmmm... to think there are people killed by a woman as thickheaded as she... it's beyond difficult to believe.
Sonia: We could do without the "thickheaded" part...
Beware the Nice Ones: Played with. She committed murder largely because she caught the despair fever, which drove her insane, but there is a very messed-up side to her that's so desperate for attention that she's willing to kill; she claims she did it for the sake of a person she loved, and it's later implied that this person was Junko Enoshima, who likely manipulated her.
Big Damn Heroes: Surprisingly, she does this during Chapter 1's trial. The others are about to vote for Komaeda as the culprit, but since Komaeda's murder plan failed, if they'd actually voted for him they all would've been executed for voting for the wrong guy. So Tsumiki saves all their lives by suddenly screaming out to wait, the wounds on the victim's body don't match the supposed murder weapon!
Chekhov's Gag: Her fanservice shots with her... interesting poses ended up being important. The first one is important because Hanamura made a lecherous comment about Tsumiki, but when the second one occurred, he was nowhere around to do so, which was proof against Hanamura and helped everyone figure out that he was the culprit. And later in Chapter 3, it's done to show that Tsumiki too, was suffering from the despair fever, thus raising her body temperature, something of which Hinata noted since she was on top of him and felt her hot body. Finally, her Free Time events reveal that she actually makes some of these poses on purpose, since she's convinced that the only way people will pay her any attention is if she humiliates herself in front of them.
The Coroner: Examines the victims for their cause of death, which often provides useful information (such as that Togami was not killed with the knife, and that since Koizumi died instantly, the killer would have had to move her body to block the door). She makes use of her knowledge by using the air conditioner to disguise her victims' time of death.
Cute Clumsy Girl: Or at least an overblown parody of one. It's implied that she exaggerates some of her clumsiness for attention, making her a rather depressing Deconstruction of this trope.
Cruel and Unusual Death: Unlike the other executions, the "cruel" part is debatable since Tsumiki doesn't actually suffer on-screen, but the "unusual" part definitely isn't. Tsumiki is laying in a hospital bed, but Monokuma runs in wearing a nurse's outfit and injects something into the bed, which causes the bed to transform into a rocket that carries Tsumiki all the way out into space. Tsumiki doesn't actually die on-screen since she's last seen holding onto the rocket for dear life, but it can be assumed that she died up there from lack of oxygen.
Desperately Craves Affection: She was bullied so severely throughout her life that she's convinced that the only way people will pay attention to her is to humiliate herself in front of them, so she deliberately plays up her Cute Clumsy Girl tendencies for this reason. When she's infected by the despair fever, a much darker side of her comes out; she commits murder in order to impress "someone she loves", who is most likely Junko Enoshima.
Dissonant Serenity: After being pinpointed as the murderer, she accepts her impending execution as a way to reach her lost love (read: Junko Fucking Enoshima).
The Dog Bites Back: Averted. Tsumiki kills Saionji because she was just in the wrong place at the wrong time, not because Saionji constantly bullied her.
Extreme Doormat: Her free-time events reveal she pretty much lets anyone do anything they want to her, specifically mentioning people stamping cigarette butts out on her or drawing on her. She lets people do these things because she believes it's the only way she can get attention, since in her mind being everyone's Butt Monkey is at least better than being ignored.
Fragile Flower: She's pretty much incapable of speaking to anyone without being on the verge of tears. Except during Chapter 1's trial, where she asserts herself and gets everyone to focus on figuring out what the true murder weapon was, and when she freaks out upon being exposed as Chapter 3's murderer, upon which she goes from "fragile flower" to "psychotic woman" to "accepting her fate way too calmly".
Freak Out: She snaps when exposed during her trial, but calms down to an unnerving degree afterward.
Giggling Villain: During her calmer phase after she is revealed to have her SHSL Despair memories back.
Hidden Depths: A very minor example, but it counts. During a Free Time event, Hinata learns that Tsumiki became a Super High-Level "Nurse" in the first place because sick and hurt people are even weaker than her, and Tsumiki can be strong enough, not to mention knowledgeable enough, to help them so they won't die. Of course, it's strongly hinted that this isn't so much out of kindness as it is for her to have actual power over someone for once, since a sick or injured person would have to depend on her completely.
Hospital Hottie: It would seem this way at first, what with her dressing in a semi-short nurse's uniform, being wrapped in bandages, and having a large bust size. However, her hair is disheveled and cut oddly, she's constantly crying or shrieking, or tripping and getting tangled in things and, in Chapter one, covered in food.
I Never Said It Was Poison: Accidentally outs herself as a culprit with this, speaking about the details of Mioda's "suicide video" even though Hinata was supposedly the only one who viewed it. As a bonus, in the segue to Panic Talk Action she starts arguing about the impossibility of a "one-of-a-kind" bag being used in the video and then being found on the real victim's head, telling Hinata she remembers it even if he doesn't.
Leave No Witnesses: She kills Saionji by slitting her throat, since Saionji walked in on her staging Mioda's murder.
The Medic: To the best of her ability. She's actually quite knowledgeable about human biology, which makes her essential for compiling autopsies about how the murder victims died. Which is why she knows, in Chapter 1's trial, that Komaeda isn't the one who killed Togami: Komaeda used a knife, but the victim was killed with something much longer and thinner than a knife.
Mood-Swinger: After being identified as the culprit during the trial, she undergoes a Freak Out, beginning to rapidly switch between manic sobbing, furious screaming, and a sinister calm.
School Bullying Is Harmless: Ahahaha, no. Mikan's been systematically abused by her peers ever since childhood, and learned that the only way anyone would be willing to pay her the slightest bit of mind was to utterly humiliate herself in front of them. In her Free Time events, if she feels Hinata's getting bored by her company, she'll offer to perform degrading acts like stripping or imitating a sea turtle laying eggs.
Self-Deprecation: It's hard for her to accept that anyone would be interested in talking to her or getting to know her at all.
Shrinking Violet: So timid, she can hardly hold a conversation without bursting into tears. At least, until she's revealed as Chapter 3's murderer, at which point she freaks. She also breaks "Shrinking Violet" character very briefly in Chapter 1's trial, when she shouts to her classmates that voting for Komaeda as the culprit would be premature.
Shut Up, Hannibal!: When Komaeda tries to call her out for murdering only for "Despair", she states she did it out of love... and suggests he can't understand because he's never been loved.
Sympathetic Murderer: An odd retroactive example of this, since when she's first revealed as a murderer in Chapter 3 it's presented as her just going nuts upon recovering lost memories, trying to impress "someone she loves", which isn't very sympathetic. However, in the last Chapter, it's heavily implied that the person she loved was Junko Enoshima; though all of the students had been slavishly devoted to her, Mikan was probably one of the most devoted due to Junko's manipulations and her own desperate need for affection.
Who's Laughing Now?: After spending the first two chapters being a Reluctant Fanservice Girl who's constantly picked on by Saionji, it's revealed in Chapter 3 that she murdered two people. Though she was infected by the despair fever to prompt her into action, there really is a darker side to her that's willing to kill if it means impressing someone she loves.
Yandere: She shows shades of this, both in Chapter 3 after revealing that she killed for the sake of someone she loved and towards Hinata in her Dangan Island ending. It's hinted that she could become a fully-fledged yandere if she's pushed too far.
A girl from an all-girls high school who played guitar in a popular "light-music club" school band, whose hit single "After-School Poyoyon Hour" sold a million copies. However, she left the band due to creative differences and is now pursuing a solo career. Despite her punk-ish appearance, Mioda is a very friendly and energetic person whose antics sometimes border the limits of comprehensibility. She is the second victim of Chapter 3, strangled to death by Tsumiki and then hung.
Anime Hair: Dark purple-black with streaks of white, neon pink, and blue, along with cones.
Bi the Way: She has a pretty obvious crush on Togami, and can get together with Hinata in Dangan Island, but says some very... suggestive things pertaining to Tsumiki and is stated in the artbook to 'like cute girls'.
Breaking the Fourth Wall: Although it could be her quirkiness, Ibuki makes frequent remarks suggesting that she is aware that she is in a video game.
"Ibuki learnt that most murder investigations involve a lot of legwork. So she's been walking her legs up and down this corridor all day!"
Covert Pervert: Less so than some of the others, but still has her moments when Tsumiki is concerned.
Creative Differences: In-Universe, she left her group due to these. Her Free Times and an official Alternate Universe manga by Spike reveal that they had a falling out when they learned a talent scout was going to be watching one of their performances, and she refused to play more traditionally appealing pop music.
Cruel and Unusual Death: A non-murderer example; while the other murder victims in this game get killed using methods that cause almost instant death (e.g. stabbed with a knife, bashed in the head, cut in the throat, death-by-really-high-fall), Mioda is unlucky enough to be killed by being slowly strangled to death with a rope. That couldn't have been much fun.
Death Metal: Her preferred genre of music. And her performances are terrifying.
Dumbass Has a Point: Of the "coincidentally correct" variant, when she suggests that the murder victim in Twilight Syndrome was killed by being hit on the head.
Fashionable Asymmetry: Her stockings are different colours, one pink and one blue. She also wears an arm warmer on only one arm.
Genki Girl: Oh hell yes. Ibuki never does anything half-way.
Hidden Depths: If her Free Time Events are done, Mioda will show a startlingly wise and contemplative side of her personality, giving Hinata some extremely profound advice about being himself, and speaking about the inner workings of group dynamics in a very emotionally intelligent way.
Horned Hairdo: While her strange hairstyle does resemble horns, it's not because she's secretly evil; rather, it's supposed to make her resemble an oni.
Scary Musician, Harmless Music: Considering that Mioda is a walking Homage to K-On! (where the main band mostly play light and fluffy J-Pop), you would expect this to be the case. Nope, it is actually full-on inverted. She's really closer to Sawako from that series: she's a delightful and peppy person to speak to but her repertoire (mostly Death Metal) is terrifying.
Ibuki is basically a walking Homage to K-On!. The kanji that spell out her name are each taken from the names of the four main characters (not including Azusa), and she used to be part of a light music club band.
Her name and design may also be a reference to Suika Ibuki from Touhou, an oni girl with horns similar to her hairstyle. Some elements of her design were also inspired by oni.
Shoo Out the Clowns: She was one of the most upbeat characters in the cast, so at the midway point in the game, of course, she had to go.
Super Senses: Super hearing, to be precise. Ibuki has the most talented "ears" of any of the cast. This proves instrumental to solving chapter 1's murder since she overhears what everyone's saying during a "blackout", causing them to realize that Togami pushed Komaeda away and got to the knife first, meaning that Komaeda couldn't have killed them.
The Cuckoo Lander Was Right: Mioda has a habit of going off on bizarre, unrelated tangents during trials. The funny thing is, sometimes she's right or her tangents lead to a critical breakthrough in the case. In Chapter 2, her sudden attempt to change the subject ("Let's talk about how she got hit with gravel instead.") turns out to be the breakthrough point of that Non-Stop Debate. Ibuki admits straight afterwards that she was just throwing stuff out there. Later on in the same trial, she also asks why Fuyuhiko is getting upset when Peko has been identified as the killer.
Third-Person Person: Instead of saying "I" or "me", she says "Ibuki". It's somewhat downplayed in the English version, since she only calls herself "Ibuki" on occasion.
A master swordswoman and kendo champion whose skill at swordplay surpasses even the strongest adult fighters. A stern yet polite woman, Pekoyama carries herself with an intimidating aura. She was an orphan taken in by the Kuzuryuu family, and serves Fuyuhiko Kuzuryuu as a bodyguard to repay their generosity. She is the culprit of Chapter 2, beating Koizumi to death with a baseball bat on behalf of Kuzuryuu. Though she implicates herself so that Kuzuryuu can claim responsibility and win freedom from the island, she is found to be the sole guilty party and is stabbed to death by an army of samurai.
All for Nothing: Peko's effort and death do not save Kuzuryuu as she has hoped, though she didn't care much for her own life either way.
Cruel and Unusual Death: She's the second culprit. And she gets a cruel and unusual death both physically and emotionally: she is literally controlled like a puppet by Monokuma and made to slash through an army of samurai, then he releases control of her just long enough for her instincts to kick in and accidentally slash Kuzuryuu, the boy she had sworn to protect.
Declaration of Protection: Towards Kuzuryuu, as she is his sworn bodyguard and self-proclaimed "tool". This comes back to bite her hard: instead of attempting to calm Kuzuryuu when he discovers a powerful motive for him to kill Koizumi, she actively plots a murder on his behalf, seeing herself as no more than an extension of his will. Her intention was to allow Kuzuryuu to escape the island by sacrificing herself and everyone else, but what she doesn't understand (under it's too late) is that Kuzuryuu did not see her as a "tool", but a cherished childhood friend he would never want to sacrifice.
Evil Albino: Sympathetic as she is, she did kill one student and attempt to condemn the others to death for the sake of her beloved master, Kuzuryuu, who didn't even want her to go through all that trouble. She even has the red eyes to go with her pale skin and white hair.
Just Following Orders: The lynchpin of her Thanatos Gambit, as the "mastermind" of a murder is considered the true culprit and she claims zero responsibility because she considers herself a "tool" without will of her own.
Platonic Life Partners: What her route in Dangan Island ultimately ends with. Hinata can't end up with her at all. Instead, they merely shake hands as a sign of friendship which is something that tends to happen often in the guy routes. The reason Pekoyama's the only female exception is because Pekoyama already has a childhood acquaintance she likes, but Hinata never finds out who it is. Since in Dangan Island Pekoyama brings up having originally felt like this person's "tool", and given what you learn in chapter 2 of the main game about why Pekoyama would ever think of herself as a tool, it's most likely that Pekoyama is talking about Kuzuryuu.
Taking You with Me: If Monokuma ruled her just a tool and that Kuzuryuu was the true murderer, everyone else would be executed for getting it wrong and he would've won the game.
Thanatos Gambit: Waited until the others offically voted her the murderer before revealing that she was Kuzuryuu's tool, knowing that if Monokuma ruled he was the true "mastermind" behind the murder, he would get to graduate while everyone else was executed.
Unreliable Expositor: After her conviction, she declares that Kuzuryuu ordered the hit, and flashes back to him smiling and congratulating her. When her gambit fails, another flashback shows him horrified and shocked.
Vigilante Man: Claims that she's the murderous superheroine Kira-Kira-chan when exposed as a murderer. However, this is a calculated lie to prevent the others from suspecting her true motive until it's too late.
The self-proclaimed "Headmaster of Despair Academy", Back from the Dead. Monokuma is very eager to see society's biggest hopefuls start killing each other, so he hijacks Usami's "field trip", mutilates her into his "little sister" Monami and imposes the "School Life of Mutual Killing" rules on the island once again. In reality, he is once again the persona of Junko Enoshima, now an AI, who hijacked the observer position in the program from Usami.
All Crimes Are Equal: Upon hearing that someone might have (but actually didn't) broken the rules by changing clothes in the beach house shower room, Monokuma quickly shows up on the scene toting a machine gun.
Big Bad: He's back to antagonize a group of students again.
Big Brother Is Watching: Much like in the first game. Only this time, his surveillance extends beyond the security cameras. Makes sense once he reveals that "he" is an AI of Enoshima who took his form for most of the game and hijacked the "observer" role in the program from Usami.
Curb-Stomp Battle: How he usurps Usami's position. He shows up and beats Usami in a fight by breaking Usami's magical staff so she's powerless against him, and then uses a friggin' giant robot with a machine gun to repeatedly shoot Usami into defeat.
Darker and Edgier: Instead of just psychologically abusing the players of the "Murder Game", this time around Monokuma actively tries to get them to kill each other, all so Junko Enoshima can have more bodies to possess.
Kick the Dog: Like in the first game, he frequently indulges in this, particularly mocking murdered or executed students.
Killer Teddy Bear: Same old homicidal stuffed toy, motivating the students to kill each other. Now digital!.
Knight of Cerebus: Minor example since it happens early. At the beginning of Super Dangan Ronpa 2, the students are led to the island because Usami is taking them on a "class trip" to help them develop their friendships, complete with things to collect to make the "game" complete. Then Monokuma shows up and sends everything straight to hell, back to the "murder" format because he thinks Usami's game is boring.
Rules Lawyer: Because he took over Usami's observer role in the simulation, he is bound to the same rules as her. This screws him over, as it prevents Komaeda's plan to get everyone killed from succeeding.
Samus Is a Girl: Once again he is controlled by Junko Enoshima, though now in AI form.
A stuffed rabbit that claims to be the class teacher of the students. She is responsible for the "class trip" and plans to cultivate hope within the students by encouraging them to befriend each other. Unfortunately, after Monokuma hijacks the island she is mutilated into his "little sister" Monomi and becomes his personal Chew Toy. Though she appears to take the side of the students, she is rather ineffectual at stopping Monokuma from imposing his murderous games upon them all. In reality, Monomi is an AI developed by Chihiro Fujisaki as an observer to the New World Program, making her Nanami's "sister". In Chapter 5, she attempts to rebel against Monokuma, which only leads to her being executed alongside Nanami.
A Day in the Limelight: The "Dangan Island" alternate universe mini-game scenario is an exploration of what would have happened if Usami had beaten Monokuma at the start of the game, preventing him from taking over. In this scenario, Usami is the "one in charge" of your game, and you gather fragments of hope just as she was originally intending for you to do.
Baby Talk: She has a very childish way of speaking, often including chu sounds in her speech. The Let's Play has her speak with Elmuh Fudd Syndwome.
Boke and Tsukkomi Routine: Often acts as the tsukkomi to Monokuma's boke (especially in chapter 1, where they play these roles in a literal comedy routine). Of course, since this is Monokuma we're talking about, he ends up violencing on Usami anyway instead of the other way around.
Bunnies for Cuteness: She's certainly a very cutesy character, what with her pink and white color scheme, her Magical Girl outfit and her childish manner of speaking.
Butt Monkey: As soon as Monokuma shows up, Usami gets turned into this, from getting regularly assaulted by him, to getting her name changed against her will and getting a makeover that puts her in a diaper. The students don't seem to have much respect for her, either, tending to think of her as an annoyance at best, and a possible accomplice for Monokuma at worst.
Cruel and Unusual Death: Nanami and the rest of the Usami/Monomi units are in a room with pixelated models, when Monokuma comes in with a tank and starts to shoot at them. Nanami suddently spots an exit and she and the Monomis run, followed by Monokuma in a ball-shaped vehicle that crushes all but one of the Monomi units. However, Nanami and the last Monomi reaches a dead end. With no more escape routes, Monokuma begins dropping Tetris blocks in the area, eventually crushing the last Monomi, and then Nanami. The blocks then explode due to Monokuma forming three perfect lines.
The Mole: According to Monokuma, she was meant to be this for the Future Foundation. Which is true, but that means she's on the students' side, although they think of the Future Foundation as an evil organization for much of the game.
Not Helping Your Case: Her reluctance to explain what's going on or her side of the story to everyone makes them more suspicious of her.
Not Quite Dead: After the survivors activate the shutdown sequence, she reappears restored to her Usami form and takes on the giant Enoshima.
Not So Harmless: She seems pretty useless at first, but then she starts taking out the Monobeasts one by one.
Only Friend: Nanami is the only one of the students who actually likes her.
OOC Is Serious Business: She's less talkative and more defiant toward Monokuma in the final trial, and you even have to face her in the chapter's P.T.A. sequence.
Punny Name: Not only did Usami start with the word for rabbit her new name sounds a lot like the French phase "Mon amie", or "my friend", much like how Monokuma's name is also a foreign language pun and the animal that he is based on.
Red Herring: In-Universe; the students are often suspicious of Monomi's motives, a suspicion that Monokuma is more than happy to exploit. Of course, in the end, it turns out she's exactly as benevolent as she appears to be.
Rules Lawyer: Insistently reminds Monokuma that he's bound by the same rules she was, particularly when it comes to protecting the lives of students who aren't being executed. This saves Kuzuryuu and Nidai's lives when they're badly injured trying to save Pekoyama from her execution, and Akane from Monokuma, respectively.
Series Mascot: Officially now shares this position with Monokuma.
Super Mode: In "Magical Miracle Girl Monomi," she can activate this by becoming Usami.
Unexplained Recovery: Even after being pumped full of lead by Monokuma, she returns in the next chapter with little explanation besides claiming that she cannot die. It's revealed in Chapter 5 that she has 10 (originally 11) copies of herself in the house. Two more blow up trying to kill Monokuma and the rest are destroyed with Nanami during her execution. In Chapter 6 this trope comes back in full force, when Usami returns due to the students' determination to find another way and defeats Junko's AI
Well-Intentioned Extremist: Apparently has the means to get the students off the island, but is instead keeping them there, supposedly to combat the aftereffects of The World's Most Despair-Inducing Incident.
A collection of 5 animal-themed giant robots used by Monokuma to keep the students in line. After they're introduced, they rip Monomi to shreds and then take up residence in front of the bridges on the central island, blocking the students from crossing them to the other islands until Monomi starts destroying them one by one.
Animal Mecha: Giant robots shaped like animals, hence the name. Specifically a horse, an eagle, a tiger, a snake and a gorilla (who was a human on the statue they spawned from).
Broken Bridge: They serve this trope for the bridges to the other islands.
Epic Flail: One of them has a spiked ball-and-chain for a tail.
Gatling Good: The flying Monobeast kills Monomi with a pair of giant gatling guns.
Living Statue: They're initially disguised as the statue in the center of Jabberwock Park, until the statue part breaks away to reveal what they really are (though the gorilla Monobeast is still wearing part of the statue on its head.)
The true mastermind behind Monokuma, whose identity is revealed in the final chapter of the game. This version of Junko is an AI which was brought into the New World simulation by Izuru Kamukura. Her goal is to download herself into the minds of the "executed" students, which would essentially clone herself. She would then go on to seize the technology from the Future Foundation, with the intent of turning the entire world into copies of herself. However, she is defeated when the surviving students refuse to "graduate" and allow her to possess their classmates, instead choosing to accept their grim pasts and resolving to create their own future. Usami then appears and destroys AI Enoshima, freeing the world from her influence.
Attack of the 50-Foot Whatever: She's absolutely gigantic, to the point that the courtroom's wall is removed in order for there to be enough space for her, and even then you usually can't see much more than her upper body. This is actually discussed when she first shows up:
Enoshima: ...but am I really that big? Isn't this actually kind of on the small side? Owari: You're big! Way too big! Enoshima: Huh? Most action game bosses are way bigger, aren't they? Like you know, that one game, God - of - War!
Body Backup Drive: Intends to download herself into the bodies of the dead students if the survivors choose to graduate, and fully intends to expand this into cloning herself into the minds of others until the whole world is filled with her identity.
Conspicuous CGI: Her avatar is full 3-D CGI, in a world where every character is drawn 2.5D, while her phone avatar is 2-D.
The Corrupter/Manipulative Bastard: How she got Kamikura on her side, presumably all the other Ultimate Despair members as well. Also how she pretends to be other people.
Master of Disguise: Enoshima is such a skilled manipulator that, given enough information on the subject, she can pretend to be anyone. This is how AI Enoshima is able to promise that she'll "resurrect" the executed classmates by downloading herself into them and then using the data she has to mimic them perfectly.
Mood-Swinger: Her entire personality and voice is still changing constantly. She's added a few more personalities to her repertoire since the first game, including Tsundere and a parody of Doraemon, though she also seems to stick to her core personality much more often.
Oh, Crap: Her reaction to Hinata rebounding from trying to break him, she recognizes him as Kamukura(strongly implied Kamukura and Hinata have merged) and begins to freak out. She clearly wasn't expecting Hinata to snap out of it, or Kamukura to show up in the game at all(she calls him a glitch/computer bug).
Say My Name: In the final P.T.A., she will sometimes scream "KAMUKURA!" as one of the statements that must be shot down.
Shout-Out: The sprite for one of her new personalities has her gain Doraemon's facial features, a reference to Monokuma's voice actress.
The Virus: Her goal is to become this, using the simulation to download her personality into all the students "died", then find a way to repeat the process for everyone.
Villainous Breakdown: When Hinata is saved from despair by Nanami (who should have disappeared by that point). Notable in that her behavior towards her defeat is not the ecstatic glee of being able to experience death, but a resigned misery at failing twice in a row and realizing that she'd be far too bored to go through with the Monokuma persona a third time.
Unreliable Expositor: Her recap of Kamukura misses several key details, including the fact that the student council's massacre was a prototype to the School Life of Mutual Killing (The way she describes it makes it sound like Kamukura went insane) and ignoring the detail that she was the person who outed the coverup to the Reserve Course as well as the fact that stirred them to begin with. This throws quite a bit of what she says into debate. She also states that everyone knew full well coming into the New World Program about her plan, which clashes with Komaeda's behaviour in the flashback that takes place just before the games events. If anything it appears that she's trying to make everything look as hopeless as possible in order to goad them into graduating.
Walking Spoiler: It's almost impossible to mention her without talking about her death at the end of the first game, or spoiling the endgame.
A multi-talented student who was so gifted that he was awarded the title of "Super High-School Level Hope" (being a superhuman who would lead humanity into a golden era). His original identity is Hajime Hinata. In spite of being an unremarkable high-school student without any special talent, he was obsessed with the thought of joining Hope's Peak Academy so he volunteered for the school's "Ultimate Hope Project", which wiped his original personality and replaced it with the constructed persona of Izuru Kamukura. Unfortunately, Izuru fell under the thrall of Junko Enoshima, who used him to murder the entire student council of Hope's Peak Academy in her first "School Life of Mutual Killing", which triggered "The Worst, Most Despair-Inducing Event In Human History". Having fallen to the ideology of "Ultimate Despair", Izuru smuggled the Enoshima AI into the New World program and caused the events of the game to unfold.
Battle in the Center of the Mind: Has one with Hinata with Nanami helping (implied to be helping both Kamukura and Hinata overcome despair and doubt) him get back on his feet.
Beware the Quiet Ones: As part of his very bored outlook about everything he doesn't speak that often unless spoken to, and the Ultimate Despair he was the first and so far only person to "Graduate" from a Mutual Killing game as Enoshima intended.
Bigger Bad: He's ultimately the one who set all the events of the game in motion, but he doesn't actively participate in it due to being overwritten by his past self in the virtual world. All we see of him in the game proper is in flashbacks.
Big Bad Ensemble: He and AI Junko Enoshima are the main antagonists, however they are NOT working together.
Brought Down to Normal: When his memories were suppressed as part of the New World program. Quite permanently, as Hinata's resolve to remain himself essentially deletes Kamukura from existence.
Creepy Monotone: To emphasize how much apathy he has toward everything he has little to no inflection while speaking.
Dark Is Evil: His color scheme and mindset both go with this. Ironic since, if Hope's Peak Academy always wanted Kamukura to look like this, as the Ultimate Hope he should have been a case of Dark Is Not Evil.
Devoted to You: Tsumiki states that all members of SHSL Despair were very devoted to Junko Enoshima. He may have been this at first, but as of now, he holds nothing but hate and the desire for revenge against her.
Eerie Pale-Skinned Brunette: His skin color appears to be a bit more paler than Hinata's usual tan skin to complement his darker hair color and red eyes, to make him look even more unnatural.
From Nobody to Nightmare: He used to be an absolutely ordinary "reserve student" before agreeing to the experiment that gave him every talent that entered Hope's Peak which helped drive him into despair.
Glowing Eyes of Doom: His eyes have a bit of a glowing tint to them, and in the flashback of Chapter 0(when we're seeing it from Hinata's point of view) his eyes are glowing.
He Who Must Not Be Seen: For a while, it isn't until during Chapter six that we finally see his identity. Even in the prequel he's been mentioned, but never actually seen by anyone.
Hidden Agenda Villain: He states towards the end of Chapter 0 that he is going to "use" the Enoshima AI in the same way she used him. What he means by this, apart from a desire for revenge against Enoshima, is never explained.
Intelligence Equals Isolation: This was the cause of his fall to despair, for he was so talented and intelligent that the world became boring to him. It's both justified and invoked in that, not only was he kept away from the rest of the world, but the Ultimate Hope Project completely wiped out any sort of personality to make way for genius, making it nigh impossible for him to connect with other people.
Kick the Dog: By Chapter 0, we already know how bad Komaeda’s self-esteem is, and how he’s usually treated by others, before Kamukura departs, when Komaeda asks if they’ll ever meet again, Kamukura states that there’d be no point. Why? He tells Komaeda that he, along with thoughts and talents bore him. Ouch.
Kill Them All: For the most part he killed all of the student council and the only other survivor gets killed off not too soon after.
Lack of Empathy: By his interactions with Komaeda, and his views of the world.
Living Macguffin: After the operations, he was supposed to become the strongest symbol of hope, then Enoshima had other plans for him...either way, he was not happy to have been used by Enoshima or even by Hope's Peak Academy.
Long-Haired Pretty Boy: His hair reaches to his feet, making it the longest of the entire cast of both games. However, his prettiness makes him more eerie than anything.
The way he views talentless people sounds very much the way how Komaeda describes his views on students like the reserve course. Being part of SHSL Despair and later on developing strong hatred for Junko Enoshima, both view her as their Arch-Enemy is another trait they both share. Also, during trial 4, when Komaeda begins to complain about how bored he is of trials and murders, he wastes no time to insult everyone whenever they're being too slow. This behavior nearly matches Kamukura's.
One-Man Army: Took on all of the student council and won, including the eldest of the SHSL Bodyguard/Octuplets.
Omnicidal Maniac: Just like Junko and the rest of the SHSL Despair, since he was a key player in the world's destruction.
Perpetual Frowner: Even when he does express any emotion, his facial expression will always be frowning.
Person of Mass Destruction: He is not only the first mutual killing graduate (Meaning he intentionally tried to kill his 15 fellow participants, and for the most part succeeded), but as the Ultimate Hope prior to becoming the Ultimate Despair he has the most destructive potential of Enoshima's entire group.
Pragmatic Villainy: Probably the only reason why he doesn't come off as monstrous as Enoshima, he finds most things very boring and would probably see no point in being sadistic, or going out of his way to get any thrill from most of the crimes he commits. Such as his desire to get revenge for Enoshima using him, the survivors of the game weren't exactly his target, but he didn't go out of his way to keep them out of harm's way at all, or even help them at all(at least until possibly towards the very end of trial six, and that's a bit of a stretch).
Rapunzel Hair: From what we see of him, his hair seems to reach down to his feet. Probably because he can't be bothered to actually cut it.
Red and Black and Evil All Over: His general color scheme, not unlike Celes's from the previous game, and yes he is plenty evil to boot, just look at his body count.
Split Personality Merge: Strongly implied to have done this with Hinata, more supported when Junko recognizes Hinata (when he has white hair and red eyes) as Kamukura rather than Hinata. At the end of the game, it seems Hinata has the dominant control over his body once again.
The Stoic: He's capable of emotion (As his thinly veiled spite towards Enoshima shows), but his world view has been so dampened he barely reacts to anything.
Tall Poppy Syndrome: Believes this to be the cancer plaguing the world, speaking from the perspective of one of the "talented".
Tragic Villain: He's a Fallen Hero who has losthopeineverything. He could've made humanity better, but the world had already become so dull to him that it made it easy for Junko to corrupt him. He was her Unwitting Pawn to help her start everything before even the prequel took place. He also became The Ace when he was Hinata Hajime because he wanted to be recognize as someone special, and not be worthless. Only to throw humanity, and even himself into despair. He's become apathetic to the point that the world he was supposed to give hope to, he rather it just be destroyed completely. He doesn't even have any empathy towards the school he once adored, if anything, he's bitter towards them for using him. Being forced to kill most of the student council had only pushed him further into having no remorse into becoming a Serial Killer. He has given up on himself, a kid who was supposed to have such great success in his life, has barely any trace of humanity left within him.His life hasn't been a very pleasant one, though he did invoked some of it on himself, and most likely without even realizing it.
Walking Spoiler: Literately everything about him, down to the fact that he exists, is a spoiler in regards to the game and DR Zero (where he was set up).
A group of Hope's Peak Academy students that fell to despair during their time at the school, and consequently fell prey to Junko's influence, to the point of accepting her Despair-based mindset as their own. The known members consist of Junko Enoshima, the original and true Ultimate Despair (as well as the Ultimate Fashionista/Analysis Girl), her sister Mukuro Ikusaba, the Ultimate Soldier, Izuru Kamukura, the former Ultimate Hope, and all the members of the Island's School Life of Mutual Killing aside from Chiaki Nanami.
Tropes Concerning The Entire Group
Adult Fear: These kids were supposed to be attending Hope’s Peak Academy so that they could have a bright future, and look what happened to them. None of them were even out of high school when they crossed the Despair Event Horizon, peformed a Face-Heel Turn, and kickstarted the end of the world in the name of a crazy teenage girl with a despair fetish.
Amnesiac Dissonance: It’s easy to forget when you see them as their pre-despair selves, but these are the same kids who end up became human embodiments of despair and who are all driven to destroy the world.
Arch-Enemy: They're at odds with the Future Foundation.
Axe Crazy: Sanity doesn't exactly exist within this group.
Bad Guys Do the Dirty Work: Any crime is within their reach; the more inhumane, the more despair it causes, both to them and the people they hurt.
Body Horror: Most if not all of them have since hacked up Junko Enoshima’s corpse to replace their body parts with her's to try and continue her existence in some way.
Brainwashed and Crazy: Enoshima's influence is considered by Makoto to be a form of brainwashing which leaves their subsequent insanity as this.
Despair Event Horizon: Each member crossed this at one time or another during their time at Hope's Peak, leaving them easy prey for Junko.
Devoted to You: All of them were very devoted to Junko Enoshima, though their reasons for their devotion vary from maniacal love to having it be twisted into hatred. They even feel this devotion after her death, which is why they turned themselves in to the Future Foundation to kick start the game's plot.
Evil Cannot Comprehend Good: Doing a Heel-Face Turn and humanity are beyond them due to Junko's influence: they had to be mind-wiped and placed in the Neo World Program to even have a chance at redeeming themselves.
More Than Mind Control: Before her death, Enoshima broke, corrupted, abused, and twisted their mental states to the point where it seems like she’s able to still "control" them beyond the grave. The crimes they continue to commit is solely based on their own "free" will.
Self-Made Orphan: They are all stated to have killed their own families in the name of Enoshima's despair.
Start of Darkness/Dark and Troubled Past: Every member had some event or series of events occur in their lives that drove them to despair, drawing Junko to them and allowing her to coerce them to join her.
Teens Are Monsters: All of them weren’t even out of high school yet when they began to kill people and destroy everything all in the name of despair.
Tragic Villain: Though not quite on Anti-Villain level, they've all have been through a lot to push them into becoming members of SHSL Despair.
Used to Be a Sweet Kid: Most of them, as seen as their pre-despair selves, were pretty decent kids before life became too much for them. Not to mention Junko Enoshima coming into their lives which only made things much worse.
Woobie, Destroyer of Worlds: All of them reached a point where enough was enough for them, and they want the world and everyone else to pay for it.
Ultimate ??? (Talent not revealed during the game)
A student at Hope's Peak and friends with a few of the students that made it onto the island (especially Koizumi.) After numerous threats made by Kuzuryuu's sister towards Koizumi, Satou confronts her about it, though the conversation eventually turns violent, with Satou eventually killing Kuzuryuu's sister and pinning the blame on a pervert who'd been in the news lately. Though Koizumi knows who the real culprit is, she keeps Satou's identity a secret, though Kuzuryuu finds out anyway and kills her. The whole story is eventually recreated in Monokuma's Twilight Syndrome game, causing Koizumi's murder as Satou's accomplice.
Ambiguous Situation: Whether Satou's killer was Pekoyama or Kuzuryuu is never explicitly stated in the game. Official materials confirm it to be Kuzuryuu, however.
Asshole Victim: Considered as such by her killer, for killing his sister, a gesture Mahiru, the friend she'd hoped to help, was not happy with at all.
Blinding Bangs: There's a much clearer shot of her in Nanami's POV Manga, but even then her bangs obscure her eyes.
The Faceless: There's only one picture of her so far, and her face isn't shown.
One Degree of Separation: Satou hung out with Koizumi, Saionji, Mioda and Tsumiki and killed Kuzuryuu's sister, causing Kuzuryuu to kill her in turn. And finding out about this information is what caused Pekoyama to kill Koizumi.
Only One Name: So far, she's only known as Satou, presumably her last name. In the localization, Chiaki, who otherwise calls people by their first names like the other characters in the localization do, refers to her somewhat formally as "Miss Satou."
Poisonous Friend: While killing Kuzuryuu's sister was not her original plan, she's not terribly bothered by having to do so, even though Koizumi is far less pleased with the idea of a murder committed for her sake.
Walking Spoiler: Hence why she's in this section. Her entire character is the central point of the Twilight Syndrome mystery, as the first murderer and second victim.
Fuyuhiko's Younger Sister
Ultimate Little Sister
As the name implies, Fuyuhiko's younger sister. She apparently bullied Koizumi at school, and was killed by D-ko when she confronted her about it, dying on the first day of the Twilight Syndrome murder mystery game.
Asshole Victim: Killed by Satou because she was bullying Koizumi, and planned on turning on E-ko as a result.
Tsundere: Described as such by her brother, saying that she treated him like an idiot most of the time, but also acted sweet and cutesy at times.
Walking Spoiler: To an extent, as discussing her reveals some of Kuzuryuu's motives, and his involvement with Chapter 2.
An organization that Monokuma claims is responsible for bringing the students to Jabberwock Island and wiping their memories, and for causing the destruction of the world. This is, in fact, only partly correct. The Future Foundation is actually an organization attempting to combat the effects of the Despairing Incident, and opposes the machinations of Super High-School Level Despair, with the assistance of the survivors of the first game's mutual killing game. The students were actually brought to the island (which is actually a computer simulation) in order to rehabilitate them after they fell under the influence of Despair.
Tropes Concerning The Entire Group
Good All Along: They aren't actually affiliated with Despair; they are their enemies.
Nebulous Evil Organisation: This is what Monokuma initially presents them as, calling them the "World Destroyers" and blaming them for the apocalypse following the Despairing Incident. Since this is coming from Monokuma, the subversion is inevitable.
Walking Spoiler: The true nature of the Future Foundation counts as this, as well as the first game's survivors being members.
A member of the Future Foundation, who (according to Monokuma) are responsible for taking away the memories of the students on the island and have placed a mole amongst their ranks. He is a returning character from the previous game, who joined the Future Foundation after escaping from the second "School Life of Mutual Killing" and is now working to rehabilitate the remnants of Ultimate Despair.
All-Loving Hero: He rebels against the higher-ups of the Future Foundation so he could attempt to rehabilitate the remnants of Ultimate Despair, instead of simply killing them as ordered.
Big Damn Heroes: Twice, since he first "saves" the Ultimate Despair against the Future Foundation's wishes by putting them in the program and then comes into the program to save them when everything starts going wrong.
Exposition Beam: Has his memories returned thanks to the Future Foundation offscreen.
The Hero: Working behind the scenes to save the survivors of Ultimate. Specifically asks Kirigiri and Togami to allow him to handle the case alone.
One of the members of the Future Foundation. She is a returning character from the previous game, and the daughter of the (original) headmaster of Hope's Peak Academy. She joined the Future Foundation after escaping from the second "School Life of Mutual Killing" and is now working to save the students from the clutches of AI Enoshima.
One of the members of the Future Foundation. He is the real Byakuya Togami, the brilliant and ruthless scion of the Togami family. After escaping from the second "School Life of Mutual Killing", he vowed to rebuild the Togami financial empire from the ground up and joined the Future Foundation. He is now working with Naegi and Kirigiri to save the students from the clutches of AI Enoshima.
Took a Level in Kindness: He's much less selfish than in the first game, and treats Naegi and Kirigiri with respect. Still far from nice, though.
In fact, the very IDEA that he's willing to put himself at risk to save the remaining students (even though he's sure he'll survive) would have been unthinkable of the first game's Togami.
Walking Spoiler: Like Kirigiri, only it also spoils the fact that the other Togami is a fake.
One of the members of the Future Foundation. Alter Ego is an Artificial Intelligence developed by Ultimate Programmer Chihiro Fujisaki (before his death during the second "School Life of Mutual Killing". Alter Ego is the administrator of the New World program, which was compromised by the AI Enoshima virus. Powerless to help the students directly, Alter Ego works tirelessly to prevent the collapse of the system and restrain the growth of the Enoshima virus as best he can.
Not Quite Dead: Believed to have been executed, and then existing just as a virus in the school network of the previous game, Alter Ego appears safe and sound, acting as the administrator of the program that Hinata and Co. are in.
