>>3752275He's talked about coming out as bisexual to his parents on his stream before. I don't like using twitch, so I mostly know him through clips and collaborations he has done with youtube-based vtubers, but a lot of his brand seems to be acting like a bratty bottom boy and lewdly flirting with other male vtubers, especially Vox Akuma. He also seems to have a particular fondness for the male characters in genshin.
I think there are some vtubers who play up a disingenuous interest in men because encouraging shippers is good for their appeal. However, I don't think Shoto is one of them. He feels genuine.
