Shunmen

Shunmen is a mountain warrior under service of Yotanwa. He is possibly the strongest Chouga (Bird) tribe warrior.

The Bird Fang Tribe was said to be the strongest of the mountain lands. Their strongest warrior was Shunmen. But eight years ago, Shuman was defeated by Yotanwa, and they were absorbed into Yotanwa's Faction. In those eight years, each time he and Yotanwa duelled he was beaten within an inch of his life.
