Kemu is the elder and former chief of the Oina Tribe in Kamui. He is hunched over with a racoondog mask and like all half-beast Oina can turn into a wolf with supposedly the best nose of all the Oina. Possessing spiritual powers he would perform the Volcanic Incantation every year at Ezofuji to cause the twin mountains to erupt and warm the land. However the twin demons there stirred and attacked Kemu who was saved by Samickle and Oki. The attack left him so weakened that he was forced to hand the position of chief to Samickle and unable to perform the Volcanic Incantation had to rely on the young Lika who is the only other person capable of fulfilling the annual ritual.
Kemu became enraged when the Oina warrior Oki took the sacred sword Kutone to face the twin demons alone and then Lika mysteriously went missing leaving Kemu with no one to search for her. He is aware of Ōkami Shiranui’s deeds and addresses her incarnation Ōkami Amaterasu as Shiranui, seeking her aid.
