After narrowly surviving his confrontation with Suitengu, Saiga has fallen unconscious into Ginza's welcoming hands - but not before telling the detective where Kagura is hiding. Yet the rogue police captain has no intention of playing the hero. She's come for Saiga, and she'll do anything to claim her prize - even if it means turning Kagura over to the enemy!

Suitengu has put his bold plan to seize control of the Tennozu Group into action, and he is moments away from completing the most important step -- marrying Shinsen, thus tying himself to the company's assets. But Kagura has learned of his intentions and breaks out of the floating research facility, with the goal of warning her mother before it's too late.

With the latest assassin on the loose, Saiga convinces Ginza to drive him from his hiding place to see Dr. Ryogoku. The samples from Saiga and Kagura have been analyzed and an eccentric DNA specialist sheds new light on the Euphoria Syndrome. Meanwhile, Suitengu continues his plan to seize control -- by marrying Kagura instead.
