Shitōshin

The Four War Gods (四闘神, Shitōshin) were four powerful demons who attacked the island of Hōraijima after its time barrier weakened. Despite their success in routing the inhabitants of the island, the priestess Kanade sealed their Spheres of Power into a comb box and lept into the Cauldron of Resonance. Unable to leave the island without their power, the Four War Gods took over Hōraijima and sacrificed half-demons in the cauldron to release a portion of their power to sustain themselves. They are eventually defeated by Inuyasha's group and Sesshōmaru. They are based on the Four Celestial Animals. The members and their respective animals are Ryūra (Dragon), Kyōra (Phoenix), Jūra (Tiger), and Gōra (Tortoise).
