Ahem

Ahem is the spirit of earth and according to rumor, Mii's ex-husband. When Natsumi inadvertently breaks the seal of Ongo's prison, Ahem appears to her in a dream and gives her Mii's necklace. He then demonstrates a perverted dance which he says will protect Natsumi in times of danger. This dance in fact unleashes the spirit of Mii, and gives Natsumi all of her powers. When Ongo became evil again, Ahem destroyed the evil spirit inside him.
Ahem's powers seem to be the ability to destroy evil with his spear, and to enlarge the spear into a pole.
