Rōyakan

Rouyakan is a wolf demon of hell, who is a gentle guardian of forest. He has the ability to spit an infinite number of three-eyed wolves out of his mouth. When no longer needed or if Rouyakan becomes unconscience the wolves disappear as smoke. One day, Naraku put a jewel shard on his forehead, and made him attack Inuyasha who had been injured. He failed and was freed from the jewel shard's power. Rouyakan returned when the panther tribe came back. He wanted to help Sesshomaru, but was denied. It was revealed that 50 years ago when the panther tribe attacked, Rouyakan was in debt to Sesshomaru's father, who had killed the leader of the panther tribe. He fought the best he could along with other demons that the Great Dog Demon had saved, but they were forced to retreat. Without the influence of the jewel shard his eyes are, wide, expressive, and blue.
