@Gokuyuske:
I guess I don't really remember the rules that well, is there a reason they can't simply restrain him?
there isn't a rule against that or violence, just a rule against killing and going in the girls' locker room.
Lot's of things can go wrong with restraining people in this situation though. For one.. if they die from malnutrition (who knows how long they'll be there), the person who forgot to feed them, take them out of walks, or whatever is now a murderer.
Two, there's now the pressure of them escaping in which case, literally ALL hell would break lose, (the fear of komeada in hiding is FAR FAR worse than him out in the open)
Still, even with those possibilities…. I'd take my chances with locking him up and him dying of malnutrition.
(Depending on what my Super Level skill is... if I was a nurse, swordsman, fireman, or mechanic... I'm not touching him)
