History Characters / KaguyaSamaLoveIsWarYuIshigami

* FriendlessBackground: In the past, Ishigami had no friends. His first friend was Shirogane and later on the rest of the student council.

* LovableJock: While he was something of a loner, he qualified during his time on the track team back in middle school. He isn't on a sports team anymore, though it's never specified if he stopped because of his suspension or if he dropped it earlier for unrelated reasons.

** Chapter 268 reveals that [[spoiler:he's been taking part in a langage exchange program. Excatly what language isn't specified, but the fact that he's doing a homestay in Switzerland would suggest that it's most likely German.]]

** By Chapter 279 [[spoiler: Ishigami rises to the rank of vice-president to Iino’s president. Becoming very well respected by the school and his fellow Student Council members.]]

* CharacterDevelopment: Ishigami, who was already a loner and had a somewhat cynical view, became even more secluded after what happened in middle school. He starts to open up to the student council and the world again over time, becomes more self-confident and starts to socialize more.

* DidNotGetTheGirl: [[spoiler: His efforts to become someone Tsubame would fall for ultimately result in this, as while she does care about him deeply, she only sees him as an underclassmen and not as a romantic partner. He does accept her friendship though, even if he's left heartbroken about it.]]

* OfficialCouple: [[spoiler:If his final chapter is any sign, he'll ''eventually'' be this with Iino. [[HereWeGoAgain after another war of love and brains.]]]]

* MeaningfulName: "Yu" (優) can mean skilled, superior, excel (in grades) or kind/gentle. While he's not actually a top student, since he's BrilliantButLazy, he is definitely a NiceGuy. Tsubame even lampshades this after the Christmas party.

* NiceGuy: It's even indicated in [[MeaningfulName his name, Yu]]. While rather gloomy, he does treasure his friendships with the student council and is happy to help, that includes Kaguya. [[spoiler:The full extent is shown in Chapter 67 when he refuses to let people mock Iino as he respects her work ethic even if they butt heads.]] Although the incident in his middle school made him lean slightly towards JerkWithAHeartOfGold territory, Ishigami's desire to help those in need is still there.

* UndyingLoyalty: For Shirogane. Giving someone validation for actions that all but broke them will do that to a guy.

* ShipperOnDeck: He admits to thinking Kaguya and Shirogane would look cute as a couple, and expressed mild disappointment when she denied having feelings for him. [[When both of them come out and admit to being in a relationship, Ishigami gives them his full support.]]

* ShipperOnDeck: He admits to thinking Kaguya and Shirogane would look cute as a couple, and expressed mild disappointment when she denied having feelings for him.

** If the ''Young Jump Love'' bonus chapter is taken as canon, [[spoiler:he knows about Hayasaka's role as Kaguya's maid (since he casts her in that role during his harem dream).]]

* WrongfullyAccused: [[spoiler:He was accused of stalking a girl he liked and getting into a fight with her boyfriend, making her transfer schools from all the commotion. However, some of this is on him; he never even tried to clear up the misunderstanding, making everyone accept the rumor as fact, though this is attributed to the threat of Otomo's boyfriend about hurting her if he let anything leak.]]

* GreenEyedMonster: When trying to set up the budget for clubs, he tried to dock the sports club 50,000 yen per couple. Seeing as he didn't have a girlfriend...

* FlowersOfRomance: Given that [[AllThereInTheManual his mother works as a florist]], his default idea for a romantic gesture involves offering flowers that have some sort of obtuse meaning behind them (such as their species names forming a backronym for a message). [[RomanticWingman Kaguya]] has to keep convincing him that such things would come across as creepy rather than romantic. [[spoiler:Iino seems to appreciate the flower he sent her anonymously though.]]

* IWantMyBelovedToBeHappy: (Presumably) Platonic example. [[spoiler:Despite cursing happy couples, Ishigami decided to make an exception and genuinely wished for Otomo to find romantic happiness. When he learned that her boyfriend cheated on her, he tried his best to keep this ugly truth away from her, thinking that she should stay blissfully ignorant to protect her happy smile, even if she started to hate him.]]

* TheUnfavourite: Chapter 111 gives a reason for his carelessness about studies, even before middle school incident: his parents just don't care about his work, his elder brother will inherit company leadership.

* BrilliantButLazy: He is acknowledged as being very intelligent (to the point that Shirogane was willing to beg him not to quit his role as student council treasurer), but he was ranked third-to-last among the first-year students and on academic probation at the beginning of the series due to his apathy towards school. Kaguya theorizes that this attitude is a result of him having been suspended for several months during his final year of middle school.

Kaguya theorizes that this attitude is a result of him having been suspended for several months during his final year of middle school. This is also implied to be the reason why Iino doesn't get along with him, since [[spoiler:she fought for him to be allowed to graduate back in middle school on the grounds that he handed in all his homework on time during said months long suspension. Seeing him squander his potential makes her feel like all her efforts were wasted.]]
