History Characters / YahariOreNoSeishunLoveComeWaMachigatteiru

** She seems to serve as this to her clique. Along with Hayama, she stands out as more insightful than her peers in noting the politics of the class. However, she struggles to rectify many of the conflicts due to her kindness.

* MoralityPet: Despite their mutual snarkiness and banter, Hachiman clearly cares about his sister and dotes on her, showing her far more tenderness than anyone else. Komachi in turn tries to have him come out his shell more.

* TitleDrop: Drops the title when her scheme to get her brother a girlfriend is ruined in one of the side-stories.

* {{Tsundere}}: A subtle, low-key example towards Hachiman. During Valentine's Day in episode 12 of season 2, she jokingly turns him down again, claiming his "attempts" to charm her won't win her over. As soon as he closes his eyes and sighs in disbelief, she immediately shoves a spoonful of chocolate into his mouth and asks if he likes sweets.

* AlwaysSaveTheGirl: Most people who come for help to the Service Club are girls. Although it's part of his role as a member of the Service Club, Hachiman is capable of going to extreme lengths to ensure that the problem is solved but always gives more priority to ensure that the girls are unharmed in any way. [[spoiler:Even if it's someone he doesn't particularly like, such as Sagami, or even if it means putting Tobe's request secondly and give priority to Hina's.]]

* ClingyJealousGirl: Though subtle, she doesn't seem too happy when she sees Hachiman on a double date with Kaori. And later when she finds out Yui went shopping with him alone [[note]]Or so she thought, as Komachi ditched the two at some point and it was to buy a birthday present for her.[[/note]], her reaction strongly hints that she wouldn't be happy seeing him with another girl, despite her claims that he disgusts her.

* CannotSpitItOut: It becomes a little obvious that she likes Hachiman, but she never states her feelings to him.

* ClingyJealousGirl: While it doesn't show up much, she doesn't seem to like it if another girl expresses interest or even just [[NoSenseOfPersonalSpace gets uncomfortably close]] to Hachiman, such as the student council president when she wanted help with the athletic festival in episode 13. She also gets a little upset when Hachiman shows a lot of interest in going to a maid cafe in episode 5 with Zaimokuza.

* TheGadfly: She likes to poke fun at Hachiman and her sister any chance she gets, all for the sake of her own amusement.

* RunningGag: Her rejections towards Hachiman, which also serve as a good indicator of her CharacterDevelopment with him.

* BadDate: Goes on a double date with Hachiman and Hayato, with her interests clearly directed towards Hayato. But at the end, Hayato reveals that he orchestrated it just to give her a TheReasonYouSuckSpeech.

* TheReasonYouSuckSpeech: Courtesy of Hachiman after she disappears before the closing ceremony for the school festival in episode 12. He gives a highly critical analysis of her hypocrisy that is so brutal that even Hayato, the residential NiceGuy, thought it went too far.

* TokenEvilTeammate: He often fills this role in order to get things done, such as finding and bringing Sagami back when she runs off from the school festival. He does get [[WhatTheHellHero called out on]] his seemingly harsh treatment of people when he does this however, even though some of them understand the intentions he has.

*** In Episode 10 of Season 2, [[spoiler: he admits that he feels inferior to Hachiman and hates him as a result.]]

* ClingyJealousGirl: When she spots Hayato on a date with Orimoto, she attempts to interrupt them, although she loses her balance due to trying on some boots. Hachiman gets Hayato out of there before Yumiko recovers from her fall.

** While Hayato is openly nice but reluctant to help others if it means hurting them, Hachiman is openly bitter but won't hesitate to assist someone in need.

* {{Foil}}: He's Hachiman's perfect opposite; popular, sociable, and nice (though not without his faults). Both ultimately have good intentions, but use different methods. Nevertheless, he has a mostly amicable relationship with him.

* Tsundere: Although she insists she [[LeaveMeAlone wants to be left on her own]], in reality, she truly wants and enjoys the company of others. However, when Hachiman is the one coming to her side, she rejects him at first but it doesn't take her long to show that [[PleaseDontLeaveMe she wants him to stay with her.]]

* FirstPersonSmartAss: While he certainly isn't afraid to voice his opinion, he tends to keep his most scathing remarks to himself.

* GreenEyedMonster: Is surprisingly prone to jealousy late in the series. Hachiman's soft spot for Iroha being a particularly annoying for her, since she goes out of her way to make sure the two are not alone with each other.

* SmallRoleBigImpact: Doesn't have much screentime (doesn't appear on screen until Season 2). But her rejection of Hachiman played a big role in shaping his cynical persona.

** BrokenAce: He's far more cynical than he lets on and due to his desire of not hurting anyone, he's practically incapable of solving anything by himself. Something that he's well aware of and hates.

** Implied to be one of the reasons for why he tried so hard to help Rumi since a similar incident occurred in elementary school, but he simply stood by at the time.

* JerkWithAHeartOfGold: She's not necessarily a ''bad'' person. Just inconsiderate and brutally blunt. She actually is (somewhat) nice to Hachiman when she's not mocking him.

* YesMan: Turns into one during the community festival committee. She just blindly agrees with anything and everything said by her classmates, despite how absurd some of those claims were.

* JerkWithAHeartOfGold: She's not necessarily a ''bad'' person. Just inconsiderate and brutally blunt.

* SmallRoleBigImpact: Doesn't have much screentime (doesn't even appear on screen until Season 2). But her rejection of Hachiman played a big role in shaping his cynical persona.
