Jinenji's father

Jinenji's father is an unnamed yōkai who met Jinenji's mother in human form after she had fallen and injured her ankle on a mountain side. He died, leaving Jinenji and his mother alone, many years before we meet Jinenji, but leaves them a herb farm. Although both of Jinenji's parents were attractive (although his mother is now aged), he did not inherit either of their good looks and is instead harassed by the other villagers because of his appearance.

Trivia
Jinenji's father and mother's infatuation seems to be one of the onscreen male demon/human woman romances on the show, that results in the conceiving a half demon offspring. Others are Tsukuyomaru and Shizu; and Inu no Taishō and Izayoi.
