- Badass Normal: He's back to his normal talentless self, aside from his reset ability, but he's pulled off some very impressive accomplishments regardless.

- Chick Magnet/Even the Guys Want Him: Hajime is a very desirable person in the eyes of many, from his polyamorous relationship in the future to the modern Cuddle Puddle now including Chiaki, Hibiki, and Gundham, with Natsumi, Monaca, Iroha, and Kana Ise also all taking a bit of an interest in him or his Kasugano persona.
- Cool Mask: He often wears a helmet with neon blue colors when disguised as Kasugano.
- Dark and Troubled Past: While he usually puts on a brave face, he's still very clearly suffering from his past experiences.

- Loving a Shadow: In Season 2, Hajime starts to realize that a lot of his feelings for Chiaki and willingness to excuse her problematic behavior stem from him harboring feelings for her A.I. version. It's because of this that he starts to recognize the gamer as a flawed but still lovable person rather than a perfect angel.

He does this to ensure that if Yasuke's multiverse theory is true, then his friends wouldn't have to worry about Kanade being a threat to them when he's gone.
- Thou Shalt Not Kill: Having witnessed ongoing bloodshed and death from the original timeline, the boy makes it a rule that neither he nor his compatriots shall kill their enemies.

Granted, he does come back, but with no idea what happened or why.
The Star

The Ultimate Gamer of Class 77-B and the deuteragonist of the series. She becomes a close girlfriend to Hajime as she joins him on his quest to save the world.
- Adaptational Sexuality: States herself to be pansexual while her, Kokoro and Mikako are discussing sexualities because Mikako's questioning hers after seeing a vision of her dancing with another girl.
- All of the Other Reindeer: Before befriending Hajime and Class 77-B, she admits that she used to be bullied for her disability, her weight, and her gaming interest.
- The Bait: In the Puppetmaster Arc, Chiaki realizes that Maverick Storm targeted her, and her family, by sending her a brochure for his island cult. Chiaki decides to use this to her advantage by pretending to accept his offer so she can get into his island base along with Hajime to take down his defenses.
- Born Lucky: Quite literally. Her mother was basically infertile but was working as a nurse during Utsuro's first miracle, which resulted in her birth.

- Disabled in the Adaptation: She has Asperger's Syndrome.
- Fetish: Chiaki admits that she has a kink for seeing her lover be intimate with other people, which is why she's a strong advocate for the Cuddle Puddle dynamic. She feels very awkward and uncomfortable admitting it, and while her friends do support her, it takes awhile for her to feel less guilty about it.
- Formerly Fat: Was quite chubby when she was a child due to an unhealthy diet, which she was bullied for. While she’s slimmed down in her teens, she’s still insecure over her weight and continues to wish she could be thinner. Or at least have smaller boobs.

- The Needs of the Many: Chiaki is always willing to offer thousands of yen from her family's income as a way of helping her friends in their world saving missions. This gets deconstructed after Maverick's defeat when the parents find out that their daughter was stealing behind their back and she didn't even bother to ask them. It also doesn't help that the Nanamis aren't as financially secure as she thought.
- One Degree of Separation: According to her mother, Chiaki's birth was partially the result of Utsuro's first miracle.
- Parental Neglect: Played With. Chiaki’s parents do neglect her, not because they don’t care about her, but because their work makes them so busy that they don’t have enough time to spend with her. Her father Tenmei does promise to whenever he can, and they do clearly still love their daughter considering how they send her to speech therapy for her Asperger’s.

- Rape as Backstory: Judging from the fact she doesn't like talking about it and she admits to Kotoko that they actually had more things in common than she knew, it's heavily implied her first sexual experience was not consensual.

- Self-Harm: Those bandages she wears cover up scars she got from cutting herself.

- Tranquil Fury: When Mikan learns exactly what Kotoko's father has been forcing her to do, she doesn't get outwardly angry, but instead adopts a haunting expression that everyone can tell means she is utterly furious beyond belief. One Anon even namedrops this trope.
- What the Hell, Hero?: She gives a hell of a speech to Chiaki for selfishly blaming her parents for Kana's death. She even chastises her lover for painting her parents in such a horrible light when in truth they're actually decent people and Chiaki herself has never made an attempt to connect with them. It's an exceptionally sore subject since Mikan's mother was a more concrete example of an abusive parent.

The Devil
Akane Taira
A competent and famous young maid who ends up entangling herself with the Quantum Crew.
- All Women Are Lustful: One of the most amorous characters in the story.
- Can't Act Perverted Toward a Love Interest: The one person she never acts overly flirty toward is Ayame.
- Cuddle Bug: That being said, her biggest desire seems to be platonic physical affection, primarily hugs.
- Deceased Parents Are the Best: Her parents died when she was a baby, and she grew up in a rundown orphanage full of abusive caretakers. Thankfully for her, it closed down and she left to pursue a successful career as a maid.
- Does Not Like Men: She likes boys, just not older men.
- Does Not Like Spam: She detests bitter coffee, but she's willing to drink it to make Sora happy.
- Everyone Has Standards: While Akane is amorous and openly pansexual, she makes it clear she doesn't perform sexual favors simply when asked.
- Friend to All Children: Akane adores kids and it's been noted she may have the strongest maternal instincts out of anyone. Unsurprisingly, she's the go-to for protecting a young Ayumu Fujimori and she has a huge family in the future.
- Harem Seeker: She's looking to build her own just like Hajime's. Sora even jokes that time travelers get harems, but relinquishes her privileges to Akane since she already has Yoruko.
- I Just Want to Be Loved: What she wants most is love, a home, and a family of her own. This is reflected in her Divine Luck.
- In-Series Nickname: Her codename is "Devil."
- The Infiltration: During the Puppetmaster Arc, she ends up falling overboard as the Crew sails away from Sunny Days Island because of an ambush. The maid ends up stranded on the island and decides to make the most of her situation by investigating on her own.
- Kid from the Future: She's the mother of five kids by 2030; two with Nikei, one with Ayame, she's pregnant with her and Yuki's child, and she's also an honorary parent to Yuki and Kizuna's daughter.
- Ninja Maid: Thanks to data Sora downloaded directly into her mind, she's become a fighter on par with Sonia.
- Polyamory: With Ayame and Nikei as of the Puppetmaster Arc. By 2030, she's also together with Yuki and Kizuna.
- Sharing a Body: Thanks to a brain implant, she and Sora essentially share a body, and can experience each others thoughts, memories, emotions and senses.
- Shipper on Deck: She completely supports Sora/Yoruko, even outright saying "I ship it" at one point.
- The Tease: She has her moments, especially when Nikei is around.
- Workaholic: She could definitely be seen as one, given her dedication to her work (both as a maid and with the Quantum Crew).
Wheel of Fortune
Sora Taira
A high-spirited A.I. based off the brain patterns of Akane Taira, and the main protagonist of Super Danganronpa Another 2. She is also the third time traveler.
- Become a Real Boy: Downplayed. She does express the desire of gaining a human body but she isn't in a rush to obtain one thanks to the many capabilities she can perform as an A.I. By the end of 2012, she eventually gains her own body.
- Benevolent A.I.: She's a sophisticated artificial intelligence and is a bonafide good guy.
- Call a Human a "Meatbag": Very fond of doing this as a joke, due to being an artificial intelligence.
- The Cracker: Thanks to being an advanced AI, Sora can break into any computer or security system. This allows her to look for documents of interest, relay surveillance footage for her allies or even tamper with security footage when breaking and entering. She can even hijack enemy robots to give herself and her friends an advantage.
- Deadpan Snarker: Mentions she could probably out-snark Hajime the moment they meet.
- The Gadfly: She likes to poke fun at others when the opportunity presents itself, and a lot of her humor is based on "tech rules, humans drool" content that Bender Rodriguez would enjoy.
- It's All My Fault: She blames herself for Akane falling overboard and getting stuck on Maverick's island due to her fear of the ocean acting up at the worst possible time.
- In-Series Nickname: Her codename is "Fortune."
- Kid from the Future: In 2030, she and Yoruko have a son named Eijiro.
- The Lost Lenore: To Yoruko originally, due to the chance she might not be created in the new timeline due to the changes happening. She breaks down crying when she discovers Sora is a time traveler as well.
- Ms. Exposition: Due to coming from the future and being more familiar with Utsuro's existence and Mikado's masterplan, she often explains to her friends and the readers about the events of SDRA2.
- Must Have Caffeine: She loves coffee, and it's one of the things she'll look forward to having when she becomes human. Naturally, it's one of the first things she enjoys when she does end up with a body.
- Official Couple: With Yoruko.
- Sharing a Body: Thanks to a brain implant, she and Akane essentially share a body, and are able to experience each others thoughts, memories, emotions and senses.
- Something Only They Would Say: Nikei is skeptical of her being the real thing, but she proves herself a time traveler by telling Yoruko what her last words were before her sacrifice in the original timeline.
- Spanner in the Works: As mentioned above, Sora can get into security systems to provide her friends with important information or make phone calls to people of interest to reach a given goal.
- Why Did It Have to Be Snakes?: Due to the failed Mass Execution from her original story, she has understandably developed a fear of the ocean.
Ten of Swords
Dr. Kyoji Nakamura
Class 75's Former Ultimate Geneticist who has questionable ties with Hope's Peak. He ultimately joins the Quantum Crew in the hopes of fixing his mistakes.
- Berserk Button: Kyoji loses it whenever Maverick Storm is brought up.
- Big Damn Heroes: Right as it seems that Maverick is finally going to drive Chiaki over the Despair Event Horizon, he shows up to confront Maverick.
- Crazy-Prepared: Knowing how dangerous Maverick is, Kyoji ensured to take extra precautions when finally facing his old enemy. This involves using undisputable evidence of Maverick having a child to mentally shock him along with wearing a bullet proof vest when the monster tries to shoot him.
- Double Agent: At first we're led to believe that he's working with Towa and the human traffickers, only to backstab them and reveal that he only joined them to gain their trust to take them out later on.
- Embarrassing Nickname: Due to dropping out of Hope's Peak due to his guilt over participating in the Kamakura Project, he was stuck with the nickname "Ultimate Dropout."
- The Friend Nobody Likes: He's convinced he's this with the Quantum Crew, although most of them don't really have a problem with him and actually consider him a friend. He just really hates himself.
- Half-Breed Discrimination: He admits that he used to be bullied a lot due to his Korean lineage.
- His Own Worst Enemy: While a kind man at heart, Kyoji's Fatal Flaw is ultimately his own crushing self-loathing over the horrible things he did. Because of his desire to make up for his past mistakes, he's ultimately done a lot more harm than good, which leads to a self-perpetuating cycle. Many people who he's hurt, such as Estu, have said all they want from him is an apology; no big gestures to fix what he's done, just a simple apology. The problem is that he's too afraid of being rejected to actually try it yet.
- Must Make Amends: His reasons for joining the Quantum Crew are to make up for participating in the Kamakura Project, murdering seven people in the process.
- My Greatest Failure: He cites being part of the Kamakura Project and experimenting on unsuspecting teen participants who ultimately died from the procedures as his greatest regret.
- Parental Substitute: He ends up becoming an adoptive father and caretaker to Monaca, as well as a mindwiped Kanade, at the end of their respective arcs.
- Platonic Prostitution: As he explains in the Old Ghosts arc, after dropping out of Hope's Peak, he hired a prostitute so he could have someone to talk to about his emotional issues, especially since he was on the verge of suicide. The prostitute, Himari Matsunaga, was kind enough to listen and helped revitalize his will to live.
- "The Reason You Suck" Speech: He gives an epic one to Maverick, claiming that the reason he tries so hard to be a big, scary monster is because of the unending trauma from his failed foster families. His need for feeding off of negative emotions and toxicity from those around him is his pathetic attempt at taking control of his life and how he's more greater then what he really is: a sad, angry little man.
- Self-Deprecation: He has a habit of bringing up his past sins and how he's a horrible person for what he did.
- Ship Tease: With Miaya and Himari Matsunaga.
- Trademark Favourite Food: His is udon.
- What the Hell, Hero?: In the Let The Dogs Out Arc, he rightfully calls out the Quantum Crew for purposefully avoiding Kanade despite agreeing to memory wipe her to make her more harmless. While he understands their reasons for avoiding her, the geneticist points out that the crew agreed to the decision yet none of them have made an effort to help her development afterwards. Especially considering that it's always been him and Monaca who frequently interact with the former yandere.
- Zero-Approval Gambit: His goal for working alongside Junya and Haiji's human trafficking ring was, in fact, to get them all arrested, including himself. Afterword, he planned to use the resulting trial to expose Hope's Peak's crimes to the world. This basically involved destroying his own reputation, but he hoped to bring all of them down with him as well.
The Hanged Man
Kanata Inori
A respectful medical expert who would one day become the Ultimate Surgeon. And after the Die Free or Live Hard Arc, she volunteers to join the Quantum Crew.
- Florence Nightingale Effect: After treating Nagito for his dementia and cancer, the two begin to spend more time together and eventually fall in love.
- Grade Skipper: She's far younger than a high schooler as she took most of her classes online. Nagito later reveals that she was admitted into Hope's Peak and is set to be part of Class 78.
- Happily Adopted: She was adopted by Dr. Hikaru Ando after her birth parents died in an accident. She would later adopt a daughter with Nagito.
- Happily Married: To Nagito in one of Mikako's visions. The two of them also have an adopted daughter named Miho.
- In-Series Nickname: Her codename is "Hanged Man".
- The Medic: She knows everything there is to performing medical procedures.
- Odd Friendship: She and Nagito bond quite a bit after treating his cancer. It later blossoms into a romantic relationship.
- Official Couple: She and Nagito become an item. And in one of Mikako's future visions, they even get married.
- Older Than She Looks: She's actually one of the oldest members of the Another cast.
Void
A subdivision of the Quantum Crew, consisting of a band of youths with harsh childhoods. Each member was blessed with Divine Luck after a chance meeting with Master Utsuro; now they have decided to help out the Quantum Crew to not only save the world but also to reunite with their miraculous master.
Justice
Nikei Yomiuri (born Arisaka)
An aspiring journalist with a bit of an ego.
- Because You Were Nice to Me: Nikei at one point admits he has a habit of developing crushes on kind people, including Akane, Yuki, and even Setsuka.
- Big Brother Instinct: Although he and Iroha tease each other often, he is very protective of her when push comes to shove.
- Heroic Sacrifice: During the Puppetmaster Arc, he tries to pass himself off as Kasugano to the angry mob targeting Hope's Peak in the hopes of rescuing his friends. Thankfully, he gets saved by the timely arrival of Ayame and Kiriko.
- Good Parents: While it's all but stated that he'll be a good father to his future children, Nikei does express worry in the present if he'll be a good enough parent given his skewed morals and bad history with his own parents. Akane assures him that him expressing worry and wanting to do better is proof enough that he will be a good parent.
- Gun Nut: He has a bit of a problem with pulling his gun out at times.
- In-Series Nickname: His codename is "Justice."
- Inferiority Superiority Complex: As Emma points out, he can be full of himself and hard on himself at the same time.
- The Insomniac: He has a bad habit of working when he should be sleeping.
- Intrepid Reporter: His talents lie in investigative journalism.
- Kid from the Future: In 2030, he has a son and daughter with Akane.
- The Leader: Of Void, before relinquishing control to Hajime after they join the Quantum Crew. This trope gets deconstructed when we learn that Nikei sought out to be the leader so he can be in control of things and has difficulty with following others. He does get better with this after talking things out with his friends.
- The Only One Allowed to Defeat You: Nikei, along with most of the Quantum Crew, believes that he will be the one to take down Hope's Peak. It's invoked due to Nikei's ability to write captivating news stories; his future article is destined to destroy HP's credibility and be the final nail on the academy's coffin.
- Rape as Backstory: Much like Kotoko, he was forced into child prostitution by his parents, which eventually drove him to kill them and run away from home. It's left him with a lot of anger and identity issues.
- Self-Made Orphan: He confesses to the Crew that he killed both of his parents in order to escape their abuse.
- Thou Shalt Not Kill: Out of all the Crew Members, he struggles the most with this rule. His righteous anger towards a designated enemy often gets the better of him which leads to Nikei voicing the desire to kill whoever they are.
- Workaholic: To the point where he's been known to work instead of sleep.Look, 24 hours isn’t nearly enough time for me to work!
The Priestess
Emma Magorobi
A fabulous actress who loves a good pun.
- Abusive Parents: Emma's biological father beat her constantly and would often put out cigarettes on her, leaving her with chronic pain well into her adulthood. She managed to get away once she met her agent, Roger, and he got her into the care of some nicer people.
- Awesome, Dear Boy: In-Universe, Emma admits to finding fame and fortune overrated and claims that while she enjoys meeting fans, especially kids and helping people in need, she acts because she likes acting.
- Cool Big Sis: She becomes this for Iroha and Masaru Daimon to the point she's considering getting the latter adopted by her parents.
- Happily Adopted: She was taken in by a wealthy British couple and couldn't be happier to call them her parents.
- In-Series Nickname: Her codename is "Priestess."
- Intergenerational Friendship: After the two meet in person, she rebuilds her bond with the now-37-year-old Kokoro.
- Master of Disguise: As a stylish actress, Emma often gives makeovers for her friends to disguise them whenever they go on stealth missions.
- Off the Wagon: During the Clouds Pass arc, she ends up taking some pain killers in order to cope with everything going on. Maku, Iroha, and Jataro only learn when they find her going through withdrawal.
- Oh, Crap!: She has a moment like this when she notices that the time traveler who they believe was responsible for Maverick and Kanade's prison escapes is moving towards towards the island resort at a rapid rate.
- Pungeon Master: Puns are her favorite kind of joke, much to the dismay of Maku.
- Recovered Addict: While she still struggles with it, Emma is working on managing her drug addiction.
- Scars Are Forever: Both internally and externally. Her father's abuse left her with burn scars across her arms and muscle and nerve damage that still cause her chronic pain.
- Self-Harm: She has a history of using opioids to cope with her pain and PTSD. At one point, she even considered overdosing.
- Trauma Button: She doesn't take the topic of child abuse very lightly as it brings back her own traumatic childhood by the hands of her abusive father.
- You Are Not Alone: She extends a welcoming hand to Iroha's siblings by assuring them that she knows what it's like to grow up and live under an abusive household and how it's always possible to escape for a better life.
Strength
Hajime Makunouchi
A boxing legend who takes his, and everyone's, health with upmost seriousness.
- Big Brother Instinct: He comes off as a big brother figure to Iroha and Masaru Daimon.
- The Big Guy: The muscle of the group and he uses his fists for justice.
- Birthday Hater: He doesn't like his birthday because it's also the anniversary of when he was diagnosed.
- Bruiser with a Soft Center: He's a big boy who eats men twice his size for breakfast, but he has a heart of gold and provides words of wisdom and support for his friends when needed.
- Chastity Couple: He is strongly against pre-marital sex and warns his friends, especially Iroha, against doing anything intimate due to being underaged.
- Granola Girl: A gender-flipped example. He loves to work out and sticks to a healthy diet. He also worries about his friends by making sure that they stay healthy too.
- In-Series Nickname: His codename is "Strength."
- One-Steve Limit: Averted. He shares the same first name with the protagonist Hinata, so most readers use his full name or surname when asking him something. His friends will often use "Maku," an Affectionate Nickname based on his surname, when interacting with him.
- Only Sane Man: He's easily the most "normal" of the Voids.
- Punch a Wall: He does this after Kana dies in the hospital.
- Reformed Criminal: He admits that he used to be part of a street gang and indulged in drugs and alcohol. He was able to get out of that environment and clean up his act.
The Hermit
Iroha Nijiue
A talented artist who's a bit of an airhead.
- All Love Is Unrequited: Played With. She gets a crush on Kasugano early in their missions together, something her friends find odd and point out he could be much older than her. Hajime and Chiaki both consider offering her a place in the Cuddle Puddle, at least until Yoruko points out that it's a bad idea; not only is she almost three years younger than them, but they're essentially treating their relationship as a safety net for everyone dealing with trauma, something that is bound to backfire if they keep it up. As such, they all decide it's best to move on.
- Ultimately averted when she does get together with Makoto and they prove to be a happy couple.
- The Baby of the Bunch: The Voids treat her like their little sister due to being the youngest and most "bubble-headed" out of the group. Though Iroha does grow out of this role when she starts to act more mature and becomes a big sister to Jataro.
- Birds of a Feather: Iroha gets along greatly with Komaru Naegi due to their love of manga.
- Cool Aunt: In the future, she becomes one to Hajime and Hibiki's daughter.
- Cool Big Sis: She becomes this to Jataro Kerumi.
- Dirty Coward: Subverted. She was this in the original timeline, but after Sora confronts her about it, she becomes determined to never go down such a path.
- Fangirl: She loves all different types of manga and anime. Her favorite being JoJo's Bizarre Adventure.
- Harem Seeker: After she gets together with Makoto, she's quite interested in forming this kind of relationship with him and all his love interests.
- Kid from the Future: In 2030, she has a son with Makoto named Noriaki. This actually proves to be an important point, as Maverick used the alias "Noriaki Naegi" when tricking Kana into working with him.
- The Kindnapper: She technically kidnapped Jataro in order to get him away from his mother, but she acts like a big sister to him and gives him all the love he never got.
- In-Series Nickname: Her codename is "Hermit."
- Official Couple: She ends up in a relationship with Makoto Naegi.
- Oh, Crap!: She panics when she realizes that Makoto is in danger due to the fourth time traveler targeting people who were important in the original future.
- The Redeemer: She actively aspires to be this for Mukuro and other such antagonists.
- Skewed Priorities: When she learns that the fake name Maverick gave Kana when he tricked her into helping him was Noriaki Naegi, which is what she wants to name her future child, she's mostly focused on the fact that this means that, in at least one timeline, she and Makoto have a child together. Granted, she's also rightly concerned that this means whoever's responsible is also aware of that fact, and they have it out for the group.
- Sympathy for the Devil: Iroha admits that she feels sympathy for Mukuro, as, while she does go on to do horrible things, having Junko as a sister is implied to have messed with her mind and that if she had a support system, Iroha thinks that she could be a better person.
- Teen Pregnancy: Kyoko reveals that she and Makoto will have their first child when she's 19 years old. It's a topic that's destined to bring about a lot of controversy among her original and Void siblings.
