Saegusa Akina admitted in a recent Marshmallow reading stream that he crossdressed in middle school. Now, he claims this didn't awaken anything in him, but he's admitted he kissed guys before, and once wanted to kiss Kanae while he was sleeping during an offcollab.
For those unfamiliar with Akina, he's basically a male version of Aqua/Pekora pretty much, and like them, joining a vtuber company helped him become more sociable, largely due to his interactions with one Aizono Manami (the two are widely believed to be dating)
