The pet cat(?). He's a bit of a brat.

A demon. He doesn't particularly like Isamu or Senzai. Having been sealed by Isamu, he is now as weak as a child. To put it simply, he's a total klutz. His lies are always seen through, and no one ever falls for his extreme pranks. He's treated as little more than a babysitter for Tama. He mostly stays out of the way but still manages to fit in well enough.
