* The RunningGag of Yuu being unable to remember his classmates' name.
** Mai's irritation at it... And telling him he should remember at least the names of [[ProudBeauty the cute girls]].
** Iwado too has trouble remembering people's names... And of course Yuu is surprised when he finally says his name right.
* Yuu's friendly chat with Iwado. All of it.
** How did it nearly cause a fight? Yuu was spooked by Iwado's arrival and accidentally made him drop his sandwich. Yuu offered to buy him another... And Iwado had him buy ''two''.
** Starting from this encounter, [[OneTractMind every time he and Yuu meet Iwado]] ''[[OneTractMind will]]'' [[OneTractMind remind him he's stronger. Multiple times. Sometimes even saying that Yuu is very strong and then immediately following it up with "But I'm stronger"]].
* Shin shows up at Yuu and Shogo's first duel... Wearing a helmet with [[Anime/MobileSuitGundam Zeon's symbol]] and a scarf with the kanji for "kill" on his mouth. A Sawakoh student promptly mocks him for it.
** The helmet is the same Shin wears whenever he goes on a moped.
* At one point Mai sees Yuu being brought in the light music club, and, knowing they're delinquents, asks Shin to go there and save him. Shin hypes himself, starts running to save him in an absolutely ''ridiculous'' fashion... Then he remembers [[MuggingTheMonster those delinquents are trying to bully the Thug Hunter of Shimokita]], [[{{Beat}} freezes mid-step]], asks Mai who is he supposed to save, and says he'll go anyway... [[PassThePopcorn To enjoy the show]]. And he ''does''.
* When they're both having trouble with the Sawakoh thugs, Shogo suggests to Yuu they ally with each other. Yuu refuses, and suggests they instead become friends. Shogo and Shin's horrified faces are priceless.
* After getting pointers on kicking from him, Yuu thanks Shogo, Shogo replies next time he'll have to pay him... And Yuu ''pulls out his wallet''. [[{{Adorkable}} And he has no idea what he's doing]].
* During his period out of his fighting form, Yuu was having trouble with three thugs... Then Iwado shows up and the three idiots do the stupidest thing they could have done: they make him ''drop his sandwich'', and refuse to buy him another.
** After ''crushing'' the thugs, Iwado asks Yuu if he saved him, and when he confirms he has Yuu buy him three sandwiches. Cue another conversation as ridiculous as their first.
* After helping him regain his old fighting form, Shogo starts suspecting that part of Yuu's trouble came from having grown too muscular and decides to check... So he demands he ''strips''. Yuu and Shin's reactions are priceless.
* The wall around Setasho High is of course full of graffiti and writings... [[DoWrongRight Including one correcting the grammar of the previous one]] and [[LampshadeHanging another calling out the correction]].
* After defeating Taka, Yuu notices that the delinquents of the whole town have started looking at him funny. Eventually, three of them corner him and Shin... And asks to take a picture with him, as now almost all the delinquents are Yuu's fans.
** Shin takes advantage of the situation to make friends... With a ''ridiculous'' impression of Tsuchiya.
** A similar scene is present in the 2005 drama too, only the delinquents catch him while he's with Mai... Who's left looking at the scene with her mouth hanging and two drinks in her hands.
* After the events of the night of his second duel with Shogo, Yuu is depressed and ignoring Shin. How does Shin react? [[WrestlerInAllOfUs Flying Body Press]].
* While he wanders in town, Yuu finds the Muscled Koala bakery, and, curious, comes in... And finds a blushing ''Tsuchiya wearing an apron and a cook hat behind the counter''. Cue FaceFault.
** Gets even better in the drama, as not only Yuu is with Mai there, but Tsuchiya is with his friends that Yuu ''grievously'' beat up during his rampage for Shin's beating, and ''they'' see Yuu first and hide behind Tsuchiya. Who promptly offers some bread to Yuu and Mai and hits on the latter (who's freaking out).
* Yuu's first friendly chat with Yoshii, partly due his shyness but mostly because of Yoshii's irritated face every time he does it.
* After being invited to the school's boxing club by Yamazaki, Yuu shows up... Wearing the PE uniform, complete with gym shoes. [[{{Adorkable}} With no idea of how ridiculous the situation looks]].
** After convincing Yamazaki to teach him proper boxing, Yuu shows up at their lesson in the same getup. [[NoJustNoReaction Yamazaki threatens to discontinue the lessons if he does it again]].
* After the first duel with Yoshito, Yuu realizes that he needs to improve his boxing and decides to take lessons from Yamazaki... Who is still terrified of him due the roundhouse kick that ended their fight. HilarityEnsues:
** At first Yamazaki doesn't even let Yuu make his request. What does Yuu do? He ''stalks him''.
** Yamazaki's WTF face when Yuu finally makes it.
** Yamazaki at first refuses. Yuu begs him, even if he wants to hit him. ''Yamazaki does just that'', before surrendering... To Yuu's ''PuppyDogEyes''.
** As said above, Yuu showing up to their first training session wearing his PE uniform and [[NoJustNoReaction Yamazaki threatening to quit if he does it again]].
** Yamazaki dealing with [[{{Adorkable}} Yuu's admiration]].
** The faces Yuu makes when Yamazaki teaches him the counter... By hitting him in the face.
** After the last lesson, Yuu asks Yamazaki if he can call him sempai. Cue Shin and Nakamura coming in to properly mock the two.
* 2005 TV drama moments:
** When they meet Shogo for the second time, Shin takes a fighting stance-and Yuu hides behind him. And then [[BlackComedy Shogo just sits down in pain from both the damage he took fighting Yuu and what his angry schoolmates did him for his defeat]].
** The third "fight" between Yuu and Yagi: Yagi is cocky, as he's got a metal bat and, even after Yuu knocked out most of his allies, still has a friend with another bat... [[ScrewThisImOuttaHere Who promptly deserts him]] because Yuu is only after Yagi. Yagi's face and quick passage from cockiness to [[OhCrap horrified realization he's done for]] is what sells it.
** The fight between Yuu and Tsuchiya has a few moments:
*** Tsuchiya is asking his two friends if they're sure Yuu is coming. They reply yes... And then ask him how does he think they got their injuries-that is, both have an arm broke, and one has a broken nose and a neck brace.
*** When Yuu arrives, they suggest Tsuchiya they gang up on him. Tsuchiya promptly rebukes them for wishing to take on Yuu with their injuries.
*** During the fight, Yuu pushes Tsuchiya back... [[RunningGag And the latter's friends are ready to jump in, and get immediately rebuked]].
*** After the fight, [[RuleOfThree the friends ask Tsuchiya why he didn't let them help him]]. This time Tsuchiya, resigned, points out it was a one-on-one fight.
*** And to make this even better... When the friends meet Yuu again they quickly hide behind Tsuchiya (see above).
** The most surreal scene of the drama: Yuu dropping some bread after being hit by a running ''Iwado''. Yuu being Yuu, he offers to share the bread he still has... But Iwado's on a strict diet to slim down.
* 2012 TV drama moments:
** The two most unlucky delinquents in any version of ''Holyland'': they try and molest Sang Mi-that is, ''Mai's counterpart''. Who is actually trying to warn them her older brother will make them pay if they don't stop when Kang Yoo arrives and tries to talk them down... [[MuggingTheMonster Only to be attacked by the two idiots who had no idea who they were dealing with]].
** During his very first appearance, Jo Gwang Su (Shin's counterpart) asks Sang Mi if she's a lesbian. She promptly hits him with her bag multiple times, tell her best friend (and his girlfriend) My Gyeong to kill him now, goes away, and then comes back to hit him again.
*** The reason he did it: he thought Sang Mi was trying to steal his girlfriend. Who promptly slaps him when he declares he knows she likes men.
** After finding out Kang Yoo is the Hunter and tracking him down, Gwang Su drags him to a cafe and tells him he still wants to be his friend and will never abandon him again, concluding with "Don't worry. Nothing's going to happen yet". [[InstantlyProvenWrong Then he looks out of the window and sees four gang members looking at them]].
