So Billy is a demon. His demon form is fairly humanoid. Whilst in his human form he can grow up to six prehensile tentacle like limbs (similar to the kagune of a ghoul from Tokyo Ghoul). Most of the time when he has them out he just has two though. Diet: Flesh, human or demon, human is easier to obtain so he avoids hunting demons. So yea. That's all I got rn.
