Yorei-ke

Yorei-ke, "ghost hair", was a fabled bushi who was named by his translucent hair.

Birth
His mother died of childbirth, and her body was sent to the crematory of Toshi no Inazuma. There, the workers found alive the infant, her mother's ghost had nursered him within the coffin.

Oni attack
Years later, an oni arrived, defeated the samurai and demanded all the children in the village. Yorei-ke substituted himself for another child, and when the oni bit him, it screamed in pain. Yorei-ke dipped his sword in his own blood and slew the thing easily.
