Tsukasa was a dangerous creature, taking the human form of a boy named Tsukasa Tenma after he killed him, but with a few… “imperfections” we’ll say…

his mouth was like a dark void and he was almost always smiling weather his mouth was open or closed. His eyes were the same. His irises and pupil black and taking up a lot of the eye. He hunts and kills humans, turning them into a meal for himself to eat.

He was stalking around the forest, searching for his next victim.
