Despite their success in routing the inhabitants of the island, the priestess Kanade sealed their Spheres of Power into a comb box and leapt 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 were eventually defeated by Sesshōmaru (Kyōra), Sango (Jūra), and Inuyasha (Ryūra and Gōra). Their true forms were destroyed forever by Inuyasha with Adamant Backlash Wave.
