And because this is a school, there's going to be classes, depending on what you chose your major to be. It can be anything, english, science, arts, your pick. (Though they actually won't take place, you can get to know a person who's in your class, RP in class, etc.)
Roommates are going to be random. There's no guarentee that Kame will end up with Jin (though WE like that a bit too much), and we're not going to change your roommate because you don't know someone's character.
Since it is a uni, you'll have to learn. ;D
There's still almost everyone left to claim (after all, we only started this com yesterday. xD)
