Meanwhile, Suitengu continues his plan to seize control -- by marrying Kagura instead.

As the Tennouzu Group gets rich off of their new product line, Saiga and Kagura set sail for a fresh start in a new land. But before they can vanish in the wind, they're dragged back to Tokyo by a powerful new ally. Everyone's working their own angle... but are they all working towards the same goal?
