Ushiwakamaru

Ushiwakamaru (牛若丸) is a young samurai from the late Heian period and early Kamakura period of Japan.

He is implied to be the savior that was prophesied to Benkei Musashibō, who would become Benkei's master after defeating him in combat.

"Showdown! Benkei Musashibō!"
Ushiwakamaru approached Benkei Musashibō as Benkei was grieving over the disappearance of Isami, who Benkei thought was the savior that had been prophesied to him.
