Nurarihyon no Mago OVA

Long before Rikuo's leadership, the Nura clan is shaped by the encounters and losses of earlier generations. Nurarihyon's youthful adventures reveal the beginnings of the company of yokai that will gather around his name.

In Rihan's time, a visit to the hot springs brings an old sorrow back into view. Setsura has kept knowledge of his vanished wife Otome to herself, and sharing it means reopening a wound that the passing of a century has not healed.
