Oka has a crush on a dude so at most she'd be bi. I'm pretty sure more recently Yandere dev has said there's one fay couple but don't quote me on that because I cannot find you that source.

I don't think I've actually heard anyone call Oka a lesbian before I've seen her shipped with girls, that's about it.
