Nitou's going to start to be getting more than a little antsy from not being able to feed on magical energy so far. He's already been chasing around a few magic users unsuccessfully, and he's about to have to make more of an effort so Chimera, the creature that lives inside him, doesn't decide to kill him for lunch instead. If you have a magic user and want an idiot running around after them claiming that he's going to eat them, then Nitou is your man.

He'll also probably be accidentally killing Gary with a syringe of neurotoxin he's going to mistake for future medicine, oops.
