History Characters / DAYS

* JuniorCounterpart: To Mizuki. Both only started soccer in high school, both were initially the worst players on the team but persevered, both didn't really have anything to keep them going before soccer, and both are kind-hearted, good-natured, simple, determined individuals.

* ThreeAmigos: With Kazama and Ubukata, once those two start getting along. The romance in there never leaves the realm of ShipTease though.

* ThreeAmigos: With Tsukushi and Ubukata, once he starts getting along with the latter.

* ThreeAmigos: With Tsukushi and Kazama, once she starts getting along with the latter.

* AmbiguousDisorder: Downplayed; he shows many hallmarks of social anxiety (inability to speak in front of a group, huge trouble speaking up when he needs something even if he needs it badly, trouble doing something that might make him the center of attention outside of soccer, trouble talking to people he doesn't know well, the tendency to not think of himself as part of the group, a latent fear of losing his friends because he can't keep up with them, and so on and so forth), but it's never named. He does slowly get better over the course of the story though.

* AmbiguousDisorder: Massive trouble expressing himself with words or understanding verbal explanations, serious about the most ridiculous things, doesn't understand what's going on around him most of the time, extremely bad at academics, no sense of direction, and a lot of difficulty with social cues, even though he tries.

* EnragedByIdiocy: Basically his default state. It's hard to find a scene where he's not lashing out, yelling at or threatening to punch one of his teammates for doing something stupid.

* {{Bishonen}}: One of the biggest ones in the series.

* {{Keigo}}: He lapses into formal speech when talking to the third-years.

* {{Keigo}}: He suddenly starts talking respectfully and using honorifics before [[spoiler:the Touin match]] and [[WeWantOurJerkBack weirding out his teammates]].

* BadassBaritone: Creator/DaisukeOno, ladies and gentlemen.

* BadassBaritone: He's the goalkeeper who has saved Seiseki dozens of times, and his voice is an octave deeper than all of his teammates'.

* SenpaiKohai: Something he takes very seriously. Rude as he is, he addresses all the third-years with "senpai" (except Mizuki, who is "Captain") and uses {{Keigo}} when talking to them.

* SenpaiKohai: Always insists on being addressed as "Hayase-senpai" by underclassmen and gets somewhat unpleasant if he isn't.

* AuthorityEqualsAsskicking: The team captain and TheAce. [[spoiler:Actually invoked by Usui, who told Nakazawa [[AsskickingEqualsAuthority the strongest player should be captain]] to get around being made captain himself.]]

* AsskickingEqualsAuthority: He gave Nakazawa this mindset [[spoiler:to get around being made captain because he was afraid of the responsibility]].

* SempaiKohai: Something he takes very seriously. Rude as he is, he addresses all the third-years with "senpai" (except Mizuki, who is "Captain") and uses {{Keigo}} when talking to them.

* SempaiKohai: Always insists on being addressed as "Hayase-senpai" by underclassmen and gets somewhat unpleasant if he isn't.

* BuxomIsBetter: His character sheet states that he likes big breasts and dislikes small ones.

* DayInTheLimelight: Chapters 41 and 42. He's the only regular in the defense during the match and has to educate and lead the other first years, including Tsukushii. Emphasis is placed on his lack of self-confidence which causes him to miss that he's a regular because of his own efforts and not just because his upperclassman graduated.
* DopeSlap: Does this to Tsukushi when Tsukushi is trying to find his own playing style, using it as an example that he can't copy Ooshiba (as Ooshiba would usually avoid his hits).

* WillfullyWeak: He doesn't want to be number one or have any titles, even though he could well be classified one of Tokyo's Big Three if he wanted, according to Hoshina. He just wants to support his team.

* NiceShoes: He wears flashy bright red cleats with his Seiseki jersey while all his teammates' cleats are black. It fits his "eccentric" label.

* CryCute: A flashback shows him crying after Seiseki lost a match in his second year, even though he just got a pro contract out of it. It's implied to be the moment that won [[GreenEyedMonster Usui]] over.

** NotSoStoic: When he starts [[WhenSheSmiles grinning brightly]] when playing soccer again for the first time after his injury, as well as in the flashback where reacts to Seiseki losing with [[CryCute tears streaming down from his eyes]].

* QuizzicalTilt: Occasionally does it when confused or thinking hard. Sometimes he takes it UpToEleven by tilting ''his entire upper body'' sideways.

* SpikyHair: UpToEleven. It's standing straight up like the crown of the Statue of Liberty.
