But on the day she moves in, she finds three handsome squatters already living in the house, and one seems to have already taken over her role!

The waters of the seven sacred falls have become polluted, and Himari, Aoi, and the shikigami cross over to the spiritual realm to find the cause. But during an attempt to purify the waters, Himari is taken away by the dragon god!
