History Characters / BlueFlag

[[folder:Omega, Mon, and Yorkie]]

* BigThinShortTrio: Omega is the short, Mon is the Thin, and Yorkie is the Big.
* TheFace: Yorkie seems to compose 90% of the group's dialogue and is the first one to interact with other characters, while Omega and Mon seem to mostly interact with each other.

* NonStandardCharacterDesign: They share designs with some other gag characters in the background of some scenes, but they're the most prominent out of all of those characters. On a handful of more serious occasions, Yorkie is drawn more realistically, but his design is still a bit outlandish.

* RunningGag: Taichi likes to jokingly compare Yorkie to a mushroom.

** Yorkie is called mushroom head and his overall looks bring to mind [[Franchise/SuperMarioBros Toads]].

* TheSmartGuy: Yorkie is the smartest of the group and he aspires to have a career in medicine.
* ThoseTwoGuys: Rarely ever are the three seen separated. Yorkie has a better time showing up separately, though.

** Yorkie found Taichi having thoughts of going to the same college as Kuze awful, since Taichi (who doesn't have an ambition of his own) is throwing away his future for a relationship that is probable to fail.

* TokenTrio: The ThreeAmigos of Kuze, Ichinose, and Mita is a variation; instead of ethnicity being the last factor of the second male/third person, it's [[spoiler:sexuality]]. Ichinose is the plain male lead, Kuze is the token female, and Mita is [[spoiler:the token gay guy]].

* OfficialCouple: [[spoiler:As of Chapter 27, Taichi and Futaba are dating... but they [[ShipSinking break it off after two years]] and Futaba gets married to somebody else.]]

* {{Nerd}}: Clearly likes video games a lot, he has multiple videogame related shirts from ''VideoGame/{{Minecraft}}'' to ''VideoGame/{{Undertale}}'', it was (and maybe still is) his dream to open a toy shop, and he certainly has the stereotypically scrawny build of one.

* AbusiveMom: At least what little we've seen of her thus far doesn't paint a very nice picture. Her brother doesn't seem much better. That said, they are willing to help prepare Kuze in wearing her yukata [[spoiler: to attract Taichi and dating him]].

** Yoneki's image in their message app is similar to ''VideoGame/{{Splatoon}}'''s playable characters.

* BaseBreakingCharacter: In-universe. There are people who think that she is adorable, sweet, and cute and her clumsiness adds to that, but to others, she is too helpless and annoying. To some, she is also using Taichi to get close to Toma, rather than befriending them.

* BigGuyLittleGuy: There's a considerable amount of height difference between Taichi and Futaba to their much taller and athletic friends Touma and Masumi.
* FirstNameBasis: Touma insists on them to start using their first names in Chapter 7, with Masumi joining this later.

** Taichi is in love with Futaba. He decides that he wants [[IWantMyBelovedToBeHappy to help her be happy with someone else if he isn't what she wants]], so he plays matchmaker between her and Touma to make sure that she finds happiness with him.
** Futaba is in love with Touma. She uses this to toughen herself up and drive herself to become more courageous and willing to take chances in order to charm the BigManOnCampus.
** Touma is in love with [[spoiler:Taichi]]. He is not sure of what to do with this and desperately tries to keep it hidden, even reacting violently when Masumi figures it out. He is happy being close with his beloved but doesn't seem willing to keep it hidden forever.

* HappilyMarried: [[spoiler:In the distant finale, Kuze is the last one of the group to marry, and she seems really happy with her new husband. Masumi has married a man that seems to be just her type and, although he is insecure about it, she seems happy with him. Touma and Taichi appear to be having a very loving married life with each other.]]
* LoveTriangle: More like a Love Square. Taichi has some feelings for Futaba, who's in love with Touma, [[spoiler:who likes Taichi]]. Then Masumi enters the picture, who turns out to have feelings for [[spoiler:Futaba]] as well.

** [[spoiler:Seven years after the end of high school, Touma and Taichi have become this.]]

* BigGuyLittleGuy: The little guy to Touma's Big guy.

* ChildhoodFriendRomance: [[spoiler:By the final chapter, he has married Touma.]]
* ChronicHeroSyndrome: Deconstructed, as he doesn't have the skill to actually do many heroic things, just the drive. This comes to a head when his attempt to save a small cat's life in Chapter 12 [[spoiler:results in Touma pushing him away to save him from a speeding car and ends up hitting Touma in his stead]].
* ClassicalAntiHero: He has no confidence in himself, and often feigns it in order to support his friend, hides a lot of self-loathing and self-doubt, tends to bottle up feelings that he thinks are unwelcome and he doesn't want to deal with. Chapter 16 shows that he has been feeling like this for a long time, especially in regards to Touma's uprise to popularity and excellence in sports.

* DidNotGetTheGirl: [[spoiler:In the middle of the story, Taichi and Kuze start dating. However, the penultimate chapter reveals that, in the DistantFinale, they had broken up two years after finishing high school, when their goals became too different. Five years after that breakup, Taichi gets an invitation to Kuze's marriage to another man. The final chapter reveals that he did get ''the guy'', though, and has married Touma.]]

** In Chapter 15, he wonders how could Touma even consider [[HeroicSelfDeprecation someone like him]] as a friend. Chapter 16 expands by showing that he distanced himself from Touma over time based on this thought as well. [[spoiler:Touma not only liked having Taichi as a friend, but also has been head over heels in love with him since they were kids]].
** In Chapter 22, he desperately tries to get Touma to tell him who is the person he likes, assuming it's Akiko. [[spoiler:He is completely oblivious that Touma is in love with him and can't say anything]].
* EasilyForgiven: In Chapter 13, [[spoiler: despite being the catalyst for Touma having his leg injured, only Yakihara and Einosuke (a junior in Toma's baseball team) show initial anger towards him, and even then they calmed down pretty quickly]]. Nobody blames him for it, but the fact they aren't mad at him actually makes him feel even worse about it.
* EndearinglyDorky: While trying to cheer Touma up and learn about what was bothering him, Taichi at one point stands up and shouts "Best Friends Power" while making a dramatic pose (a reference to a board game they made together when they were younger). Touma can only roll over in laughter at how silly Taichi looked. Taichi for his part is instantly embarrassed that he did it.
* FirstLove: [[spoiler:To Touma]].

* HeroicSelfDeprecation: Following Chapter 12 and [[spoiler:Touma's accident]], Taichi finds himself in a spiral of self-loathing, not being able to understand why no one is hitting him or hating him for [[spoiler:being the one to cause Touma's injury]] and the fact that Futaba, Seiya, and even Touma don't hold anything against him actually makes him feel even worse.
* IWantMyBelovedToBeHappy: He decides to help Kuze conquer Touma, despite being in love with her, because that's after all that she wants. Deep down, however, he wonders and fears if he is actually rooting for her failure.
* ManlyTears: Finally breaks down in Chapter 17 over [[spoiler:Touma's accident]] and how guilt-ridden he is about it as he begs forgiveness and desperately tries to think of a way to make it better, though he doesn't even know how to start compensating others for what he has done and yet again, no one blames him.

* TheMatchmaker[=/=]MatchmakerCrush: Both get deconstructed. Ichinose attempts to get Touma and Kuze together, however he slowly starts to fall for Kuze. It gets deconstructed when facing Masumi, he starts feeling like a shitty person for helping a girl with something he is also hoping that she'll fail in. As she also points out, his matchmaking isn't taking in consideration that both Touma and Kuze might come out of it with their feelings hurt, which Ichinose can't notice because he is in a position in which his feelings cannot be hurt directly, different than theirs.
* MomentKiller: Touma [[spoiler:almost tells Taichi about his crush on him after Taichi finds out that Touma is not actually crushing on his sister-in-law. Taichi, in his earnestness to let Touma know that he has his back no matter what, is concerned that Touma might go a bit over the top and shouts "Best Friend Power" while doing a Sentai pose, referencing the board game he and Touma drew up as little kids. Touma is just shocked into laughter and lets the moment pass without telling Taichi the truth.]]

* KindHeartedCatLover: Loves cats and confesses to Masumi that his greatest regret was not helping a cat that as run-over by a car when he was 6. [[spoiler:Then, when he does save a cat, Touma is the one to get hit by a car]].

* OrdinaryHighSchoolStudent: Which is the reason why he and Touma didn't connect as much during high school, as while Touma is TheAce, he is just a normal student. This gets discussed during Chapter 10, [[spoiler: where while wanting to consult with Touma about Touma not wanting to go to university, he hesitated since he felt he doesn't have the right to]].
* PositiveFriendInfluence: Taichi has been a huge source of support as Futaba attempts to grow more determined and assertive to get the man she wants. It's also implied that, by rebuilding their friendship, Touma has been happier for a while.
* SurvivorGuilt: He develops this when [[spoiler:Touma pushes him out of the way of a speeding car and gets hit in his stead]]. The fact that nobody blames him for it actually makes it worse, even though Touma survived the hit and went on to recover. Everyone states that it was Touma's decision and that Taichi shouldn't think of any way that he is at fault, but this just makes him feel bad.
* WeUsedToBeFriends: Taichi drifted apart from Touma as they grew and Touma started attracting people towards him, many of whom don't really seem to be interested in Taichi. Though played with in that Touma never stopped seeing Taichi as a friend, Taichi just felt out of place in the popular kids crowd that grew around Touma. Touma uses senior year as an excuse to continue their friendship.

An impossibly naive girl who fell for Touma. She ends up befriending Ichinose in an attempt to learn more about him, but they end up becoming close friends with each other and Touma as well. She is very sweet and tries her hardest, but her natural clumsiness and naivete make it hard for her to befriend others in her class.

* BaseBreakingCharacter: In-universe. There are people who think that she is adorable, sweet, and cute and her clumsiness adds to that, but to others, she is too helpless and annoying. To some, she is also using Taichi to get close to Touma, rather than befriending them.
* BecauseYouWereNiceToMe: The reason she falls in love with Touma.

* ExactEavesdropping: She is at a shop at the exact time some other girls show up and start talking about Touma, Ichinose, and her. Some make mean remarks about her, but others compliment her and confirm that Touma asked her and Taichi to join the cheer squad in order to get them together. In order to not make things awkward, however, she pretends to have only noticed the girls as she and Masumi leave the store.

* LovingAShadow: Futaba eventually realizes that she isn't really in love with Touma, she just loves who he is and wants to be like him. This is around the time that she realizes that she ''does'' like Taichi in a romantic way after all the time they've spent together.

** Falls for Touma due to him being one of the few people who's actually nice to her whenever she screws up.

[[folder:Touma Mita]]
!! Touma Mita / [[spoiler:Touma Ichinose]]

* AbortedDeclarationOfLove: [[spoiler:He almost tells Taichi about his crush, before Taichi suddenly starts shouting about ThePowerOfFriendship during a game they played as kids, prompting Touma to laugh and stop his confession]].

* ForcedOutOfTheCloset: [[spoiler:Kensuke overhears him stating that he's in love with Ichinose to Mami and promptly starts a fight. Subsequently, the story about the fight has spread and everyone knows about Touma's sexuality in school, though not everyone knows about his crush on Taichi (some think he's in love with Kensuke).]]

* {{Gayngst}}: [[spoiler:It's heavily implied Touma is going through this, though he already has accepted his own sexuality, his reaction when Masumi finds out is to be absolutely terrified.]]

* TryingNotToCry: In Chapter 17, as he watches [[spoiler:the game he couldn't participate on]], his face starts contorting before he quickly attempts to smile to Taichi. As they watch it together, Taichi breaks down crying and apologizing, leading Touma to cry as well.

* {{Gaydar}}: Apparently has a ''really'' good one, seeing as how [[spoiler:she could tell Touma was gay without even holding much of a conversation with him. It's eventually revealed that it was because she began to watch him after learning that he was Kuze's crush, but she remains the only character ever confirmed to figure his sexuality out on her own.]]

** To Touma in Chapter 5:

->''"Something's been bugging me for a while. Why are you and Touma Mita such good friends?"''

-> ''"Touma, do you really... hate me?"''

A girl that is within Touma's group of friends and grows upset with his newfound interest in hanging out with Futaba and Taichi instead of her. She is interested in Touma, but he does not reciprocate her affection.

* AmbiguouslyEvil: In the second semester, she suddenly decides to become close to Taichi, to the surprise of many. This has led to in-universe speculation over whether she is genuinely trying to become a better person and befriend people, and those who think she is just trying to manipulate Taichi to get closer to Touma, or even trying to get between Taichi and Kuze. [[spoiler:It's later implied that she is just genuinely trying to become a better person]].
* AbhorrentAdmirer: Played with in the sense that Touma isn't the one abhorred by her, but rather, she antagonizes all of his friends. Touma is aware of her feelings for him, but he couldn't care less, being just generally very neutral about her, while she actively antagonizes everyone she notices to be outside of her social circle and close to Touma, which means Masumi, Taichi, and Futaba.

* AscendedExtra: Early on she was little else than a nuisance that caused mild havoc and annoyance to Touma. Later on she tones down her advances, but ironically her screemtime skyrockets as she tries to genuinely befriend the main group and her backstory and philosophy are explored.
* ClingyJealousGirl: Is all but stated to be in love with Touma and is clearly uncomfortable with him wanting to spend time with Ichinose and Kuze over her and her friends. Turns out this made her wildly disliked among other women, who think she is hogging Touma for herself, despite having been clearly turned down and stopping them from spending time with him. Some girls think she is only allowed around because Touma's friend likes her.

* HopelessSuitor: She is implied to be this. She is into Touma but he doesn't really seem into her, at least not as much as he is into hanging out with his friends and especially [[spoiler:considering Touma is in love with Taichi, she is barking up the wrong tree]].

* OneOfTheGuys: She desperately would like to be one. She has more masculine interests in movies and video games, but whenever a guy she's friends with starts dating someone else, he cuts off his friendship with her because he doesn't want his girlfriend to get any ideas about them. And all of her girl "friends" think she is being a slut by hanging out with so many guys to the point that they have zero sympathy when she got unwillingly groped, thinking she was asking for it. [[spoiler:Shingo is the only one who understands this and doesn't mind hanging out with her, even at the cost of losing his girlfriend who did think he was two-timing. Even Kensuke, who has a crush on Mami, finds it bizarre that they could be "just" friends.]] And as seen in OperationJealousy below, she [[spoiler:really was trying to join Taichi's group of friends without any ulterior motives (well, none beyond seeing what it is about Taichi that makes Touma spend so much time with him.)]]
* OperationJealousy: Masumi assumes she is doing one of these when she suddenly starts hanging out with Taichi despite previously showing nothing but contempt for him, especially since she starts doing it right after he starts dating Futaba. [[spoiler:It turns out her intentions are pure, if poorly timed. Depressed that all of her attempts to get Touma's attention have failed, and seeing that he has such a great friendship with Taichi -- one that's different from his normal clique -- she tries to befriend Taichi to see what's so different about him.]]

* SocialCircleFiller: PlayedForLaughs. Mami is Touma's ''friend's friend'', he doesn't really have any interest in her and when they hang out it's because they have that same friend going. As a result, Touma often simply forgets about her altogether, no matter how many times she attempts to become closer to him. In Chapter 21, he even forgot to invite her to a get together at his house.

* {{Tsundere}}: Mami is a mostly very harsh and unpleasant girl that showcases a more cute and sweet side when around Touma.
* UnrequitedLove: For Touma. She is also desperately trying to get him to notice her, but he has never done anything except turn her down, leading her to believe that he hates her. [[spoiler: This comes to the point where even if she couldn't really be his girlfriend, she decided that trying to become one of his best friends is enough for her before he started dating someone else]].

Two of Touma's friends that he hangs out with when not with Taichi or baseball. Shingo is rather laidback while Kensuke is very serious.

** Shingo seems like a general slacker and, at times, prankster. However, he [[spoiler:is one of the few people who understands Mami's plight. He is friends with her without any of the baggage of them being the opposite sex, and even when his girlfriend breaks up with him because she thinks he is two-timing with Mami, he doesn't mind and continues being friends with Mami, unlike every other pme of Mami's guy friends who distance themselves once they get girlfriends.]] This also leads him to give Touma [[spoiler: a WhatTheHellHero when Touma refuses to outright reject Mami despite clearly not being interested in dating her, which is stringing Mami along and making her depressed.]]
** Shingo is also more perceptive than what it seems and in Chapter 33, he calls Touma out for hiding something.

* RedOniBlueOni: Shingo is laid-back and calm, but at the same time, surprisingly perceptive of other people and in-tune with the atmosphere and their feelings. Kensuke is passionate, impulsive, and emotional. [[spoiler: Which is why Taichi and the others are initially surprised when Shingo actively gets in a fight with Touma due to Mami]].

* TragicBigot: [[spoiler:During the argument in Chapter 43, Kensuke reveals his homophobia was brought on as a product of being molested by a man when he was younger. He knows that not every gay guy is like that, and he does recognize Touma as one of those people, but he can't separate the incident from the group.]]

Touma's older brother. He has been taking care of him ever since their parents died. He is a down-to-earth guy who worries a lot about not only Touma but also Taichi. Currently married to Akiko.

* AloofBigBrother: Following his parent's deaths, he immersed himself in law school, leaving Touma to fend for himself at home. See ParentalNeglect below.
* BigBrotherInstinct: Not only for Touma, but also to Taichi. As soon as he meets Taichi in the hospital, he gives him a talk about how not only [[spoiler:Touma's accident]] wasn't his fault, but also that he has no reason to feel guilty about it. He even puts his number in Taichi's phone in case he wants to talk to someone about things.
* EarlyBirdCameo: Doesn't show up in-person until Chapter 13, but he can be seen in a picture at Touma's house back in Chapter 4.
* EstablishingCharacterMoment: In his first major appearance in Chapter 14, he is level-headed, attempts to console Taichi over his guilt [[spoiler:over Touma's accident]], and offers his phone so they can talk.
* MenCantKeepHouse: Chapter 48 shows he left the family home a pigsty, with mountains of unwashed clothes and papers everywhere. The house only got clean because Akiko came by to help out. This in particular is justified due to Seiya and Touma having a hard time adjusting to life after their parents died.
* NiceGuy: A very calm, level-headed man, who tries to console Taichi as he is guilt-ridden for what he did to Touma. When Taichi asks to be hit as a way to pay for what he has done to Touma, Seiya just gives him a knock on the head and states he is just happy that everyone is OK, even giving Taichi his cellphone so they can talk in case Taichi needs it.
* ParentalNeglect: A downplayed version, also with a sibling instead of a parent. After their parents died, Seiya spent so much time studying for law school that he kind of neglected Touma and the house. We see that a young Touma accidentally overloaded the washing machine with tons of dirty clothing because he didn't know how to do it and Seiya was too busy. The rest of the house is equally filthy. Akiko takes it upon herself to clean up the house.
* PromotionToParent: Following their parent's deaths, he became Touma's legal guardian. It seems that he still acts and considers himself a big brother rather than a parent.

* StrongFamilyResemblance: Played with in the sense that he is extremely similar to Touma, not his parents. They have similar faces and even hairstyles. Despite never meeting him before, Futaba is able to instantly recognize him as Touma's brother.
* {{Troll}}: He enjoys embarrassing both Touma and Taichi. At one point, he threatens to tell Futaba a lot of shameful and funny stories from Taichi's childhood if he doesn't help him to get through to his brother.

[[caption-width-right:300:''"Touma! Tai! Just follow me!"'']]

Touma's former tutor and current sister-in-law, married to Seiya. She is an eccentric but very nice and upbeat woman who presents herself as Touma's big sister. She knows Taichi from their past and appears happy that he and Touma are close again.

* AmazinglyEmbarrassingParents: While she isn't Touma's parent, she is married to his legal guardian and is capable of making him blush in embarrassment as she goes on to pinch Kuze's cheeks over how cute they are. When she takes Taichi and Touma to their house, she briefly mentions to Touma that he should hide his erotic books, embarrassing him in front of Taichi.

* EstablishingCharacterMoment: Showing up and telling Touma his brother is coming home early, so she is getting some shopping done for dinner and telling Taichi how much he grew up, and almost immediately guilt-tripping the two "young men" Touma and Taichi to take her groceries to the car.
* {{Foil}}: To Kuze. As Touma's ideal girl, she is the complete opposite of Kuze, both physically and in personality, showing the difference between who Kuze is and what kind of girl Touma likes.
** [[spoiler:Subverted when later, she turns out to not really be Touma's ideal girl]].
* {{Foreshadowing}}: Touma describes his ideal woman as having a mature vibe, but when Akiko first shows up, she is eccentric and upbeat, not really exhaling maturity, [[spoiler:showing that this description wasn't about her, and he was using her as a RedHerring]].
* TheGadfly: She appears to take some enjoyment in embarrassing Touma in front of his friends.
* HotForTeacher: A tutor of Touma's and a very beautiful woman, to the point it was implied that Touma was in love with her when he was younger. [[spoiler:Subverted when Touma turned out to have accidentally used her as a misdirection]].
* NiceGirl: She is kind and amicable to Touma's friends as soon as she meets them.

* RedHerring: [[spoiler:When describing his type, Touma's description matches Akiko, with Taichi believing that he is in love with his older brother's at-the-time fiancée. He isn't, that was an accidental way for him to hide that he is in love with Ichinose]].

[[folder:Touma's Parents]]

* DeceasedParentsAreTheBest: They died very early in Touma's life and they're implied to have been great parents to both him and his older brother.

* AllLoveIsUnrequited: Ichinose falls for Kuze, who has a crush on Mita already. [[spoiler:Mita is in love with Ichinose and Masumi is in love with Fuataba. Later Futaba starts to fall for Ichinose ]]. Most are unaware of this cycle.

** Masumi is in love with [[spoiler:Futaba]]. She decides it's better to not deal with these feelings, keep them hidden and look for someone else that might give her more stability. She seems to be the one holding the largest amount of emotional baggage due to this.

* OfficialCouple: [[spoiler:As of Chapter 27, Taichi and Futaba are dating...but they [[ShipSinking break it off after two years]] and Futaba gets married to somebody else.]]

* AgeAppropriateAngst: Ichinose never really gave much thought to what he wanted to do of his life, this [[SurprisinglyRealisticOutcome comes back to bite him now]], as he faces his last year of high school and faces a wave of anxiety while attempting to decide whether to go to college or try something else. Starting high school romance in a love triangle between him, his ChildhoodFriend and the naive Kuze adds to the complications as well.

* ChildhoodFriend: To Toma
* ChildhoodFriendRomance: [[spoiler:By the final chapter, he has married Toma.]]

* DesperatelySeekingAPurposeInLife: As he realizes it's his last year in high school, he realizes he needs to start deciding how to take his life from there onward. He regrets not going through these decisions before.
* DidNotGetTheGirl: [[spoiler:In the middle of the story, Taichi and Kuze start dating, however, the penultimate chapter reveals that, in the DistantFinale, they had broken up two years after finishing high school, when their goals became too different, with 5 years after that breakup, Taichi getting an invitation to Kuze's marriage to another man. The final chapter reveals that he did get ''the guy'', though, and has married Touma.]]

** In Chapter 15, he wonders how could Touma even consider [[HeroicSelfDeprecation someone like him]] as a friend. Chapter 16 expands by showing that he distanced himself from Touma overtime based on this thought as well. [[spoiler:Touma not only like to have Taichi as a friend, but also has been head over heels in love with him since they were kids]].

* EasilyForgiven: Chapter 13 [[spoiler: Despite being the catalyst for Toma having his foot injured, only Yakihara and Einosuke (a junior in Toma's baseball team) showed initial anger towards him, and even then they calmed down]]. Nobody blames him for it, but the fact they aren't mad at him actually makes him feel even worse about it.

* FirstLove: [[spoiler:To Mita]].

* EndearinglyDorky: While trying to cheer Touma up and learn from him what was bothering him, Taichi at one point stands up and shouts "Best Friends Power" while making a dramatic pose (a reference to a board game they made together when they were younger). Touma can only roll over in laughter at how silly Taichi looked. Taichi for his part is instantly embarrassed that he did it.

* HeightAngst: Implied in the first chapter, when he tries to grab a book on a high shelf for the already short for a girl Kuze, only to realize he himself is basically the same height as her.

* IWantMyBelovedToBeHappy: He decides to help Kuze conquer Mita, despite being in love with her, because that's after all that she wants. Deep down, however, he wonders and fears if he is actually rooting for her failure.

* TheMatchmaker[=/=]MatchmakerCrush: Both get deconstructed. Ichinose attempts to get Mita and Kuze together, however he slowly starts to fall for Kuze. It gets deconstructed when facing Masumi, he starts feeling like a shitty person for helping a girl with something he is also hoping that she'll fail in. As she also points out his matchmaking isn't taking in consideration that both Mita and Kuze, might come out of it with their feelings hurt, which Ichinose can't notice because he is in a position in which his feelings cannot be hurt directly, different than theirs.
* MomentKiller: Touma [[spoiler:almost tells Taichi about his crush on him after Taichi finds out that Touma is not actually crushing on his sister-in-law. Taichi in his earnestness to let Touma know that he has his back no matter what is concerning Touma goes a bit over the top and shouts "Best Friend Power" while doing a Sentai pose, referencing the board game he and Touma drew up as little kids. Touma is just shocked into laughter and lets the moment pass without telling Taichi the truth.]]

* OrdinaryHighSchoolStudent: Which is the reason why he and Toma didn't connect as much during high school, as while Mita is TheAce, he is just a normal student. This gets discussed during Chapter 10, [[spoiler: where while wanting to consult with Mita about Mita not wanting to go to university, he hesitated since he felt he doesn't have the right to]].

* SurvivorGuilt: He develops this when [[spoiler:Touma pushes him out of the way of a speeding car and gets hit in his stead]]. The fact that nobody blames him for it actually makes it worse, even though Touma survived the hit and went on to recover. Everyone states that it was Touma's decision and that Taichi shouldn't think of anyway that he is at fault, but this just makes him feel bad.

An impossibly naive girl who fell for Touma. She ends up befriending Ichinose in an attempt to learn more about him, but they end up becoming close friends with each other and Touma as well. She is very sweet and tries her hardest, but her natural clumsiness and naivete make it hard for her to befriends others in her class.

* CuteClumsyGirl: Deconstructed. While Kuze is indeed adorable, her cuteness helps at nothing in regards to her clumsiness, and with her constantly messing up tasks her classmates and family give her, they become understandably angry at her and don't care abotu how cute she looks.

* ExactEavesdropping: She is at a shop at the exact time some other girls show up and start talking about Touma, Ichinose and her. Some make mean remarks about her, but others compliment her and confirm that Touma asked her and Taichi to join the cheer squad in order to get them together. In order to not make things awkward, however, she pretends to have only noticed the girls as she and Masumi leave the store.
* ExpositoryHairstyleChange: In the very first chapter, where after listening to Ichinose's advise, Kuze cut her hair short in order to attract Mita.
* HopelessSuitor: [[spoiler:Considering Chapter 5 reveals that Mita is gay and in love with Ichinose, Kuze and the girls in their school have spent a long time barking up the wrong tree]].

* MomentKiller: Downplayed in Chapter 32, [[spoiler: during the heated conversation between Mami and Masumi, she suggested that Mami open her mouth to stop her crying. But after that session, with Masumi's prodding, she brings out her own insecurity towards Mami and Taichi being close]].

* ShrinkingViolet: [[spoiler: Stems from being told by her classmates that she would fail at doing things & living in a household that does not see her as dependable. Which causes issues her when she panics during her cheer demonstration in the sports festival. Ichinose quickly snaps her out of it]].

** Falls for Touma due to him being one of the few people who's actually nice to her when she screws up.

Kuze's best friend. She is a dark and mysterious girl, who is very protective of her smaller best friend. She is in a separated class but is often seen hanging around with the rest of the main characters. She intends to become a veterinarian and implies she is dealing with a lot of emotional issues.

* AngerBornOfWorry: She blows up with Ichinose over his matchmaking, since it doesn't take Kuze's schedule or feelings into consideration. She later apologizes, but asks him to be careful and wary of her feelings.
* FakeGuestStar: While she doesn't appear in the covers (though she did appear in the second volume backcover, photographing Taichi, Kuze, and Mita behind their back), she had a major role as the 3 leads.
* FirstNameBasis: After Taichi found her crying after breaking up with her boyfriend and they had a conversation about relationships and other things, she told Taichi that he should just call her by her first name since they had become friends.

* HasAType: Both of her in-story interests, Kuze and [[spoiler:her husband]], are light haired, shy and easily flustered individuals with their hearts on their sleeve.

* KeepingSecretsSucks: [[spoiler: Her biggest problem regarding her sexuality isn't being able to confess to a person she likes, but more towards her keeping a secret and unwilling to reveal it feels like she's deceiving everyone]].

* AerithAndBob: Other characters have fairly normal Japanese names. This trio has very weird ones that in the most, don't even seen like names at all.

* BigThinShortTrio: Omega is the short, Mon is the Thin and Yorkie is the Big.

* FreezeFrameBonus: A panel in Chapter 14 shows their real names, as written in Taichi's cellphone. it also shows they have a group chat called "Dead World Denizens". Their real names are (supposedly) Ryohei Okuda, Yuuto Yoneki and Monji Murasame.
* {{Gonk}}: Their largely cartoony style and nearly caricatural faces makes them look like this.
* NonStandardCharacterDesign: They share designs with some other gag characters in the background of some scenes, but they're the most prominent out of all of those characters. In a handful of more serious occasions Yorkie is drawn more realistically, but his design is still a bit outlandinsh.

* ThoseTwoGuys: Rarely ever the three are seen separated. Yorkie has a better time showing up separately though.

** Towards [[spoiler: Mami's friends Hasudi & Mochizuki when they wanted Taichi to have a consultation with Shingo and Kenseke after the school culture fight, seeing that it takes time away from Taichi's entrace exams]].

A girl that is within Touma's group of friends and grows upset with his newfound interest in hanging out with Futaba and Taichi instead of her. She is interested in Touma, but he does not reciprocates her affection.

* AmbiguouslyEvil: In the second semester, she suddenly decides to become close to Taichi, to the surprise of many. This has led to in-universe speculation over whether she is genuinely trying to become a better person and befriend people and those who think she is just trying to manipulate Taichi to get closer to Touma or trying to get between Taichi and Kuze. [[spoiler:It's later implied that she is just genuinely trying to become a better person]].
* AbhorrentAdmirer: Played with in the sense that Touma isn't the one abhorred by her, but rather, she antagonizes with all of his friends. Touma is aware of her feelings for him, but he couldn't care less, being just generally very neutral about her, while she actively antagonizes everyone she notices to be outside of her social circle and close to Touma, which means Masumi, Taichi and Futaba.
* AlphaBitch: She fits the bill in character and is even the cheerleader in Chapter 8. While downplayed in Chapter 13, she is one of the few who openly blames (but thankfully didn't go further than giving him an ugly look to) Taichi before leaving the hospital after visiting Toma, and usually acts slightly hostile towards Taichi and Futaba before the second semester which she cools down towards them (though her hostility towards Masumi continues).
* AscendedExtra: Early on she was little else than a nuisance that caused mild havoc and annoyance to Touma. Later on she tones down her advances, but ironically her screemtime skyrockets as she tries to genuinely befriend the main group and her backstory and philosophy are explored
* ClingyJealousGirl: Is all but stated to be in love with Touma and is clearly uncomfortable with him wanting to spend time with Ichinose and Kuze over her and her friends. Turns out this made her wildly disliked among other women, who think she is hogging Touma for herself, despite having been clearly turned down and stopping them from spending time with him. Some girls think she is just allowed around because Touma's friend likes her.
* ExpositoryHairstyleChange: She cuts her hair in Chapter 28, following that, she has become friendlier towards Taichi and his group of friends, started playing video games and has been generally nicer to everyone.

* LikeBrotherAndSister: The sister to [[spoiler: Shingo's brother. They hung out in middle school and helped each other during hard times (Mami sided with Shingo when he is assaulted by her admirer, Shingo sided with Mami even with one of his exes complained about her existence) and stayed at this relationship at Mami's urging]].
* NoIndoorVoice: Masumi had to keep her consistently in check for shouting during [[spoiler: the intervention of what's going on between Mami & Taishi]].
* OneOfTheGuys: She desperately would like to be one. She has more masculine interests in movies and videogames. But whenever a guy she's friends with starts dating someone else, he cuts off his friendship with her because he doesn't want his girlfriend to get any ideas about them. And all of her girl "friends" think she is being a slut by hanging out with so many guys to the point that they have zero sympathy when she got unwillingly groped, thinking she was asking for it. [[spoiler:Shingo is the only one who understands this and doesn't mind hanging out with her, even at the cost of losing his girlfriend who did think he was two timing. Even Kensuke, who has a crush on Mami, finds it bizarre that they could be "just" friends.]] And as seen in OperationJealousy below, she [[spoiler:really was trying to join Taichi's group of friends without any ulterior motives (well, none beyond seeing what it is about Taichi that makes Touma spend so much time with him.)]]
* OperationJealousy: Masumi assumes she is doing one of these when she suddenly starts hanging out with Taichi despite previously showing nothing but contempt for him, especially since she starts doing it right after he starts dating Futaba. [[spoiler:It turns out her intentions are pure if poorly timed. Depressed that all of her attempts to get Touma's attention fail, seeing that he has such a great friendship with Taichi, one that's different from his normal clique, she tries to befriend Taichi to see what's so different about him.]]
* SoBeautifulItsACurse: A downplayed example. She has made so much of her public identity about putting a beautiful face forward that her friendship circles start falling apart whenever her friends start relationships. The guys are unable to see her as just a friend as a girl and her girl friends are afraid she is going to try to steal their boyfriends. [[spoiler: Thus her flashback she tries to downplay her attractiveness, including having a tomboy look which she didn't care at all. When that fails (and hurts Shingo as well), she decided to not give a damn]].
* SocialCircleFiller: PlayedForLaughs. Mami is Touma's ''friend's friend'', he doesn't really have any interest in her and when they hang out it's because they have that same friend going, as a result, Touma often simply forgets about her altogether, no matter how many times she attempts to become closer to him. In Chapter 21, he even forgot to invite her to a get together in his house.
* SurprisinglyRealisticOutcome: A boy attempts to get her to go out with him by breaking up with his girlfriend and asking her to go out with him if he wins the next game of the school festival. She is understandably grossed out that this guy would throw his girlfriend away for someone else he doesn't even know and has no reason to believe that gesture was romantic nor that he wouldn't do the same to her. [[spoiler:When Kenta does this, she is pissed again]].

* UnrequitedLove: For Touma. She is also desperately trying to get him to notice her, but he has never done anything but turn her down, leading her to believe that he hates her. [[spoiler: This comes to the point where even if she couldn't really be his girlfriend, she decided that trying to become one of his best friend is enough for her before he started to date someone]].
* VisualDevelopment: As of Chapter 28, she has cut her hair to shoulder length and seems to have a more mature look to her. [[spoiler: Her past also showed that she changes hairstyle a lot, which includes a tomboy look]].

* FirstNameBasis: Touma insists on them to start using their first names in chapter 7, with Masumi joining this later.

* OfficialCouple: [[spoiler:As of chapter 27, Taichi and Futaba are dating...but they [[ShipSinking break it off after two years]] and Futaba gets married to somebody else.]]

* ChronicHeroSyndrome: Deconstructed, as he doesn't have the skill to actually do many heroic things, just the drive. This comes to a head when his attempt to save a small cat's life in chapter 12 [[spoiler:results in Touma pushing him away to save him from a speeding car and ends up hitting Touma in his stead]].

** In chapter 15, he wonders how could Touma even consider [[HeroicSelfDeprecation someone like him]] as a friend. Chapter 16 expands by showing that he distanced himself from Touma overtime based on this thought as well. [[spoiler:Touma not only like to have Taichi as a friend, but also has been head over heels in love with him since they were kids]].
** In chapter 22, he desperately tries to get Touma to tell him who is the person he likes, assuming it's Akiko. [[spoiler:He is completely oblivious that Touma is in love with him and can't say anything]].

* HeroicSelfDeprecation: Following chapter 12 and [[spoiler:Touma's accident]], Taichi finds himself in a spiral of self-loathing, not being able to understand why no one is hitting him or hating him for [[spoiler:being the one to cause Touma's injury]] and the fact that Futaba, Seiya, and even Touma don't hold anything against him actually makes him feel even worse.

* ManlyTears: Finally breaks down in chapter 17 over [[spoiler:Touma's accident]] and how guilt-ridden he is about it as he begs forgiveness and desperately tries to think of a way to make it better, though he doesn't even know how to start compensating others for what he has done and yet again, no one blames him.

* BaseBreakingCharacter: In-universe. There are people who think that she is adorable, sweet and cute and her clumsiness adds to that, but others, she is too helpless and annoying. To some, she is also using Taichi to get close to Touma, rather than befriending them.
* BecauseYouWereNiceToMe: the reason she falls in love with Touma.
* BoyishShortHair: {{Downplayed|Trope}}. She cuts her long and fluffy hair on chapter 1. Her new hairstyle is short and she still seems fairly feminine with it, but it shows he has become a {{Determinator}} and much more prone to take action towards her objectives.

* HopelessSuitor: [[spoiler:Considering chapter 5 reveals that Mita is gay and in love with Ichinose, Kuze and the girls in their school have spent a long time barking up the wrong tree]].

* MomentKiller: Downplayed in chapter 32, [[spoiler: during the heated conversation between Mami & Masumi, she suggested Mami to open her mouth to stop her crying. But after that session with Masumi's prodding, she brings out her own insecurity towards Mami & Taichi being close]].

** Falls for Touma for being one of the few people to actually be nice to her when she screws up.
** [[spoiler:She later falls for Taichi for him being supportive, kind, and helping her with whatever she wants.]]
* StageFright: In chapter 9, she [[spoiler:gets frozen when leading the cheer for Class A, but snaps out of it when Taichi helps her out]].

* AbortedDeclarationOfLove: [[spoiler:He almost tells Taichi about his crush, before Taichi suddenly start shouting about ThePowerOfFriendship withing a game they played as kids, prompting Touma to laugh and stop his confession]].
* BaitAndSwitch: Mita describes his perfect girl using the same characteristic his tutor/sister-in-law have, which Ichinose thought that he has a crush on her. [[spoiler:He doesn't, he is actually lying because he is actually interested in Ichinose]].
* BewareOfTheNiceOnes: [[spoiler: After he confesses his crush to Mami and Kensuke overheards them, Kensuke starts a fight with him. When Kensuke insulted his sexuality, he reacts harshly towards Kensuke and even twisted Mami's words when Mami tries to stop their fight]].

* ChildhoodFriendRomance:[[spoiler:He is married to Ichinose in the distant finale.]]

* ForcedOutOfTheCloset: [[spoiler:Kensuke overhears him stating that he's in love with Ichinose to Mami and promptly starts a fight, subsequently, the story about the fight has spread and everyone knows about Touma's sexuality in school, though not everyone knows about his crush on Taichi (some think he's in love with Kensuke).]]

* HeroicSacrifice: [[spoiler:Gets hit by a car in Ichinose's place to save him. Though he survives, his leg gets broken, ending his last chance to reach nationals on his baseball team, which was his only real dream.]]
* IJustWantToBeFree: His reason to decide to [[spoiler:planning to not go to college and leave his brother's house]]. In his eyes, he isn't truly free yet, and lacks any clear direction in life at this point, deciding that he' be happier just starting his own life where no one can interfere.

* InnocentBlueEyes: His eyes may or may not be actually blue (since its black and white), but his irises are noticeably brighter than just about any other character in the manga, and are very very noticeable whenever we see him staring at Taichi. And he definitely fits the trope, he doesn't seem to have a mean bone in his body, and is extremely affable.
* InnocentlyInsensitive: He gets a WhatTheHellHero from one of his friends for basically stringing Mami along by never outright rejecting her advances, making her think she maybe has a chance with him and making her increasingly jealous and bitter towards Taichi, Futaba, and Masumi and eventually not showing up to events because of said jealousy.

** A lot of moments in chapter 22 were him giving these to [[spoiler:Taichi]]. Possibly wondering whether to say anything or not.
* LovableJock: A sweet and nice guy who is great at sports, member of the baseball club and basically the school's most desired guy.

* NotSoDifferentRemark: While Masumi stated that they are the same in chapter 5, he refuses this in a later chapter, probably referring to [[spoiler:how they intend to deal with their same-sex crushes]].
* TragicDropout: [[spoiler: Zigzagged. While Mita is willing to complete high school, he plans not to go to college, even though it seems contradictory of his goals of being a professional baseball player.]]
** A few chapter later, it's revealed that [[spoiler:he came to that decision on his own, he intends to move out and start working after high school, despite his brother is begging him to go to university. In his own words, it's because he yearns to be free.]]
* TryingNotToCry: In chapter 17, as he watches [[spoiler:the game he couldn't participate on]], his face starts contorting before he quickly attempts to smile to Taichi. As they watch it together, Taichi breaks down crying and apologizing, leading Touma to cry as well.
* SingleWomanSeeksGoodMan: Rare male example. [[spoiler:He falls for Ichinose and while talking with Kuze, he talks as if he is infatuated by Ichinose's kindness, caring nature and love for cute things]].

* UnrequitedLoveLastsForever: It's heavily implied that his crush on [[spoiler:Taichi has been there ever since they were kids and has only grown since then]]. Subverted in the final chapter, [[spoiler:revealing that his love was eventually reciprocated, and he married Taichi.]]

* AloofDarkHairedGirl: Masumi, the tall and mysterious girl who is also Kuze's best friend. Deconstructed when she reveals in chapter 11 that she fears her aloofness makes her a person less capable of love and sees her unwillingness to meddle with problems that aren't hers or her friend's a thing that makes her cold and uncaring.

* FakeGuestStar: While she doesn't appear in the covers (though she did appear in the second volume backcover, photographing Taichi, Kuze & Mita behind their back), she had a major role as the 3 leads.

** To Touma in chapter 5
--> '''Masumi:''' [[spoiler: Black hair is the only thing that fits the bill, right? Because the person you really like is [inaudible, but shocked Mita enough to react harshly against her]....I didn't tell him. But it's true isn't it? You're the same as me.]]
** To Ichinose in chapter 11

** The receiving end of this from Akiko in chapter 39
--> '''Akiko:''' [[spoiler: If it that you're keeping a secret and your inability to reveal it makes you feel as if you are deceiving them]].
* WhenSheSmiles: In chapter 11, she gives a kind and genuine smile to Taichi after he consoles her. It's beautiful.

* FreezeFrameBonus: A panel in chapter 14 shows their real names, as written in Taichi's cellphone. it also shows they have a group chat called "Dead World Denizens". Their real names are (supposedly) Ryohei Okuda, Yuuto Yoneki and Monji Murasame.

* AlphaBitch: She fits the bill in character and is even the cheerleader in chapter 8. While downplayed in Chapter 13, she is one of the few who openly blames (but thankfully didn't go further than giving him an ugly look to) Taichi before leaving the hospital after visiting Toma, and usually acts slightly hostile towards Taichi and Futaba before the second semester which she cools down towards them (though her hostility towards Masumi continues).

* ExpositoryHairstyleChange: She cuts her hair in chapter 28, following that, she has become friendlier towards Taichi and his group of friends, started playing video games and has been generally nicer to everyone.

* SocialCircleFiller: PlayedForLaughs. Mami is Touma's ''friend's friend'', he doesn't really have any interest in her and when they hang out it's because they have that same friend going, as a result, Touma often simply forgets about her altogether, no matter how many times she attempts to become closer to him. In chapter 21, he even forgot to invite her to a get together in his house.

* VisualDevelopment: As of chapter 28, she has cut her hair to shoulder length and seems to have a more mature look to her. [[spoiler: Her past also showed that she changes hairstyle a lot, which includes a tomboy look]].

* BrutalHonesty: When Kensuke is asked by Mami's friend in what does he sees it her, he bluntly says it is all about her physical appearance.

** Shingo seems like just a general slacker and at times prankster. However, he [[spoiler:is one of the few people who understands Mami's plight. He is friends with her without any of the baggage of them being the opposite sex, and even when his girlfriend breaks up with him because she thinks he is two timing with Mami, he doesn't mind and continues being friends with Mami unlike every other of Mami's guy friends who distance themselves once they get girlfriends.]] This also leads him to give Touma [[spoiler: a WhatTheHellHero when Touma refuses to outright reject Mami despite clearly not being interested in dating her, which is stringing Mami along and getting her depressed.]]
** Shingo is also more perceptive than what it seems and in Chapter 33, he calls Touma out for being hiding something.
* IGotBigger: Flashbacks show that during middle school Shingo can be similar to Taichi & Futaba in appearance and demeanor, which in the present shown him grow up and be attractive to girls.
* RedOniBlueOni: Shingo is laid back, calm, but at the same time, surprisingly perceptive of other people and in-tune with the atmosphere and feelings. Kensuke is passionate, impulsive and emotional. [[spoiler: Which is why Taichi and the others are initially surprised when Shingo actively gets in a fight with Touma due to Mami]].

* VitriolicBestBuds: Despite Mami is angry about Kensuke's attitude towards girls and would frequently argue with him about it, Taichi noted that they are willing to reconcile and be friends again.

* BigBrotherInstinct: Not only for Touma, but also to Taichi. As soon as he meets Taichi in the hospital, he gives him a talk about how not only [[spoiler:Touma's accident]] wasn't his fault, but also that he has no reason to feel guilty about it. He even puts his number on Taichi's phone in which case he wants to talk to someone about things.
* EarlyBirdCameo: Doesn't show up in person until chapter 13, but he can be seen in a picture at Touma's house back in chapter 4.
* EstablishingCharacterMoment: In his first major appearance in chapter 14, he is level-headed, attempts to console Taichi over his guilt [[spoiler:over Touma's accident]] and offers his phone so they can talk.

* NiceGuy: A very calm level-headed man, who tries to console Taichi as he is guilt-ridden for what he did to Touma. When Taichi asks to be hit as a way to pay for what he has done to Touma, Seiya just gives him a knock on the head and states he is just happy that everyone is OK, even giving Taichi his cellphone so they can talk in case Taichi needs it.
* ParentalNeglect: A downplayed version, also with a sibling instead of parent. After their parents died, Seiya spent so much time studying for law school that he kind of neglected Touma and the house. We see that a young Touma accidentally overloaded the washing machine with tons of dirty clothing because he didn't know how to do it and Seiya was too busy. The rest of the house is equally filthy. Akiko takes it upon herself to clean up the house.
* PromotionToParent: Following their parent's death, he became Touma's legal guardian. It seems though he still acts and considers himself a big brother rather than a parent.
* SavvyGuyEnergeticGirl: Seems to be the more calm and cool counterpart to his wife's upbeat, eccentric and cheerful wife.

* {{Foreshadowing}}: Touma describes his ideal woman as having a mature vibe, but when Akiko first shows up, she is eccentric and upbeat, not really exhaling maturity, [[spoiler:showing that this description wasn't about her, and he was using her a RedHerring]].

* NoSenseOfPersonalSpace: As soon as she meets Itachi and Futaba, she jumps on Futaba to pinch her cheeks over how absolutely adorable she is. After seeing Taichi, she also starts poking him in the cheek to talk how handsome he has become.
* RedHerring: [[spoiler:When describing his type, Touma's description matches Akiko, with Taichi believing that he is in love with his older brother's at the time fiancée. He isn't, that was an accidental way for him to hide that he is in love with Ichinose]].

* SchoolgirlLesbians: [[spoiler:Even though she dated a man, she didn't quite feel romantically or sexually inclined to him. However, she does have feelings for Kuze, which she admits to Ichinose in Chapter 11 before [[JustJokingJustification backpedaling]]]].

** Gives these to [[spoiler:Taichi]] fairly often. [[http://mangafox.me/manga/ao_no_flag/v03/c016.5/4.html This]] is the most blatant example.

* NotSoDifferent: While Masumi stated that they are the same in chapter 5, he refuses this in a later chapter, probably referring to [[spoiler:how they intend to deal with their same-sex crushes]].

* AgeAppropriateAngst: Ichinose never really gave much thought to what he wanted to do of his life, this [[RealityEnsues comes back to bite him now]], as he faces his last year of high school and faces a wave of anxiety while attempting to decide whether to go to college or try something else. Starting high school romance in a love triangle between him, his ChildhoodFriend and the naive Kuze adds to the complications as well.

* RealityEnsues: A boy attempts to get her to go out with him by breaking up with his girlfriend and asking her to go out with him if he wins the next game of the school festival. She is understandably grossed out that this guy would throw his girlfriend away for someone else he doesn't even know and has no reason to believe that gesture was romantic nor that he wouldn't do the same to her. [[spoiler:When Kenta does this, she is pissed again]].

* ArmoredClosetGay: [[spoiler:Reacts fairly harshly when Masumi finds out about him being gay, out of fear she told anything to Ichinose]].

* {{Gayngst}}: [[spoiler:It's heavily implied Touma is going through this, though he already has accepted his own sexuality, his reaction when Masumi finds out is to be absolutely terrified]].
