Birthday: April 9 Height: 181 cm Weight: 73 kg Rihan is Nurarihyon's son and Rikuo's father. He resembles his father and he too has long hair that protrudes out the back of his head. Unlike Nurarihyon, however, his hair is purely black and more wavy. Born the son of Nurarihyon and Yōhime, he was often taken around on his father's patrols (much to his mother's dismay). During the Edo period, he took over as the Second Head of the Nura Clan. Under his leadership, the Nura Clan's power reached its peak and he was responsible for stopping the actions of The String Assassin of Hitachi Province.
