Risu

Risu is tall and has a muscular build similar to Kaiman. Inhabitants of the Hole assumed he was Kaiman with his restored human face. His hair is dark-tipped and sometimes sticks up in spikes, but through most of the story it lays flat. He wears a single piece grey suit with no sleeves, later seen sleeved with a thick collar. Large, nail-shaped stakes are attached to his chest, arms, and legs.
