HI i have plenty of akito hcs... i'll try to include only the ones that don't really have an effect on anything in canon bc i think that's what you mean? sorry if i misunderstood tho i tend to do that 🫡

• he really likes sports anime/manga !! haikyuu and blue lock especially. i don't know anything about blue lock but i think he would like tanaka from haikyuu. and iwaizumi. oh and definitely coach ukai. and he would probably have a little crush on kita who said that. he probably also reads some basic shounen stuff like jjk csm etc. but i can't say anything about those bc i know almost nothing about them
• i feel like he would fw this heavy. and these
• he has moderately bad vision but refuses to get glasses or contacts. like sure he has to squint to see anything in the distance but he's got more important things to worry about
• he has freckles !! but you usually can't see them in my art bc i don't think he has many on his face. (he does have Some there, though. i just usually forget to draw them.) they're mostly on his arms and back etc
• has only a few playlists on spotify. he's got one to get him hyped before shows and one he listens to while he falls asleep and a couple other miscellaneous ones and then he just has The Mega Playlist for every other occasion (on his runs, while chilling at home, previously at work, at school etc) and it's got like 9,000 songs on it
• has an INSANE spice tolerance
• nowadays he only uses social media to promote vbs stuff but if you scrolled down really far on his tiktok you'd find his old dance videos and he does Not speak about those
• he listens to every artist and genre ever but with vocaloid specifically i think he'd especially like hachi and jin! and umetora... and maybe like giga and hachiouji-p but i feel like he'd lean more towards rock than edm despite liking both. an would be the giga hachiouji-p yunosuke listener
• since everyone in the game has an image color it's hard to tell whether said color is their favorite or just the one that represents them; i think it's safe to say akito's favorite color is in fact orange but i think he also likes red a lot
• he sings Really Loud in the shower god save ena shinei and unnamed shinonomom
