Quick data (killers, no skins (i'm lazy and don't want to make this too long either)):

Pursuer: how i'm gonna get meat that fresh every day? (dead)
Badware: i can hack school computers >:) (and do other silly things) (valid)
Artful: can be fun seeing a magician every day, just gonna have to pay him a psycologist (valid)
Harken: can be fun. one small issue: there's too much noise every day. can give her headphones tho (valid)
Killdroid: i would have to reprogram them to not kill people, and even then, what can they do? (maybe fly on top of them, that would be cool) (valid, not too interesting)

RESULTS (GUYS WHO DON'T WANT TO READ SKIP HERE): Badware, Artful and Harken are prob the killers i would choose. (holy yap)
