Kettu is a flirtatious, sadistic man who spends his time annoying people rather than doing what he's supposed to, which is gathering human souls. He's never been in love before, mostly using people for their bodies... and occasionally, their souls. He doesn't get upset much, and he's a very physical person who'll go so far to annoy someone that he'll literally poke a stranger and go "hey- hey. Heeyyyy-! Stop ignoring meeeee!" He never shows his tails or ears. He has nine tails, as the name says.
