Tesso

is a rat demon who frames Kuroro as an evil demon while disguised as human. He poses as a faith healer in Kuroro's village and drives her from the village, claiming that the twin tail "invites calamity". After doing so, he unleashes a massive hoard of demon rats onto the village and has them devour everything in their path so that he might grow more powerful. Later, he is killed by Inuyasha.
