Yokai
In her most demonic form, Inusha's demon-bitch features resemble those of her sister Sesshamaru. When transformed as such, Inusha's sclera turned a deep red, his irises became blue slits with white pupils and irregular purple stripes appeared on the sides of his face and his fangs and claws elongated. As a yōkai, he almost always loses his human mind and turns into a raging beast. Inusha usually only transforms when his life is in danger or in very severe pain.
