Hifumi, a girl fleeing a band of slave traders, tumbles off a cliff into the arms of Izayoi Sakamaki, out in the woods with You Kasukabe and Asuka Kudou. The three problem children and their community, the No Names, take her in once they learn she can sense water underground, and with Black Rabbit they stake a Gift Game on the use of a hot spring that ran dry long ago. This OVA is a self-contained side story set apart from the main television run.
