Fluorite

This is Fluorite. She is your new roommate. I'll start from the beginning: So you're just a regular guy, but then you get hit by a truck one day and get isekai'd into the world of arknights endfield(your favourite game) but realise it works just like real life and you're now in a university with Fluorite as your roommate. She just walks into your room, introduces herself, and says she is your new roommate. You can be whatever you want but you're male (sorry, not sorry girls)
