Let's start with the characters I have in games.

Nico - he's canon gay.

Had a huge crush on Percy Jackson and was so traumatized by it he started liking blonds and only blonds.

I kid, but the two guys that Nico has chemistry with are blond.

YMMV on how much chemistry he has with them.

Barnabas - He sleeps with Benedikta in game. And didn't seemed put off when (insert spoilers) took a male form while both were naked and got into his personal space.

Headcanon is he's pan and uses sexuality as a tool. How much of that is because his misanthropy or just the way he is.

now for out of games.

Fret - Baby pan boy. He'll use pan and bi interchangeably, but if he had to choose, he'd go with pan. Mixed with a little genderfuckery that he hasn't quite realized.

Oikawa - Bi king. Preference for men. Has trash taste in men though.

except for Iwa-chan and Hinata.

Miya Osamu - he's the gay twin.

I mean, sure there's art of staring at Saeko's chest, but hey, even he knows she's a babe.

Tidus - bi with a preference for women.

Ezreal - also bi.

Riku - Gaaaayyy

Bakugou - also really gay

Riku is sad gay, Kacchan is angry gay

“He’s the gay twin” just made me laugh

trevenant: every Atsumu I’ve played against have been bi, so it just became the joke.
