Tesso

was a rat yōkai who framed Kuroro as an evil demon while disguised as human. He posed as a faith healer in Kuroro's village and drived her from the village, claiming that the twin tail "invites calamity". After doing so, he unleashed a massive hoard of demon rats onto the village and had them devour everything in their path so that he might grow more powerful.

Later, he was killed by Inuyasha, who realized the giant Tesso he was fighting was an illusion and destroyed the real Tesso, hiding inside a rock, with the Kaze no Kizu.
