Boarding House AU Sandbox-Thing

Okay, so just like my Plurk suggested, I want to do a sort of boarding house type thing where people can toss their characters.

I've got two options:

a.) Normal: Basically, everyone's AUed as a human, and lives...more or less normally. Either the house could've just been built, or they could've been here for a while. Depends on if people would rather build CR or have assumed CR.

b.) Ayakashi-Kan 2.0: In Inu x Boku SS, the Maison de Ayakashi is a sort of mansion/boarding house for those of supernatural origin and their bodyguards. While bodyguards certainly aren't necessary, it could be amusing. Everyone has some sort of weird power or something like that. Probably a mix of assumed and CR building (if you'd like to be a new resident).


With those options out of the way, here are the other details I have laid out.

-8 Floors, Basement, Rooftop, Garden.
-Rooms are pretty large. Reference! (Yeah, they're fancy af)
-4 rooms per floor. 1st floor is lobby/cafeteria. 8th is communal bath.
-Max of 2 people per room. So a total of...28 characters? Unless there's demand for more. Maybe have two complexes? Opinions?
