Relapse

Kiri's usually an incredibly sweet guy, but in the past he wasn't quite as lovely. Some events in his past made him choose to go as straight-edge as a demon can get away with which works well until he has the occassional relapse, in which he's a bloodlust crazed, well... demon!
It's hard to deny basic nature and he's never proud of what he's done, once he comes to and has to deal with his overtaxed, gore-filled belly. :c
