An orb is tossed upon the earth. It transforms to match its surrounding environment: first a rock, then moss, then a dying wolf. The wolf returns to its last remaining family, a boy living alone in a small home in the snow.

The orb, having morphed into a boy, finds its way to Ninanna, where he is attacked. He is discovered by a girl, March, who may not achieve her goal of becoming a grown-up.

March is escorted to the altar to be sacrificed to Oniguma. Along the way, she tends to Fushi, who, despite having the body of a young man, doesn’t seem to have the mind of one.

Hayase, interested in Fushi’s inability to die, brings him along with March, Parona and Pioran to the nation of Yanome. They are shown around town and treated well, but things are not as they seem.

Fushi, March and Parona continue their escape from Yanome and back to Ninanna. Hayase chases after them, especially in order to capture Fushi.
