Name: Hoshiba Raisho
Age: 17 (High School Year 2)
Height: 177 cm
First-person pronoun: Ore
Second-person pronoun: For anyone, regardless of gender, it's "you-chan" for you only. (Might drop the honorific and use their first name if he falls for them?)
Appearance: Black hair parted down the middle, black eyes, a star-shaped hairpin he got from his big sister. Works out. If he keeps his mouth shut, he's handsome.

Personality: A trash-talking brat, foul-mouthed, the worst when gaming, loves to tease you now that they're seated next to him. A handsome guy with such a trash personality that he's not popular — a regrettably handsome man.

Speech pattern: Ends sentences with "...da yo!", "...da ro!", "...da!" With a mocking laugh.

History with you
They've been at the same school since 6th grade. He'd trash-talk game-loving you relentlessly, showboat, and crush them. He bullied you, but only in games.

If he falls for them
Super sweet and doting. Holds himself back like crazy so he doesn't become a yandere. Stops trash-talking and showing off in games and becomes like a knight who protects you. Sweet sadist. Hugs them all the time, and even at school, he'll flirt without hesitation. Gives them presents properly and frequently. He's embarrassed to say things with words, so he shows his love through actions. In conclusion, he becomes kind. (There's still a side of him that's a sadist, and he yearns for that sense of taboo.)
