It's a dangerous race across Tokyo as Saiga tries to find a safe place to hide Kagura, settling on a small night club in the seedy entertainment district. Meanwhile, another gifted Euphoric is called to bring Kagura home: Madam Koganei. A high-class woman who fuels her power by swallowing priceless diamonds.

With the ability to turn her body into solid diamond, Madam Koganei seems impervious to Saiga's attacks. Not only is she virtually unbreakable, but the diamond's reflective quality makes it impossible for Saiga's camera to focus. After a high-speed chase through the city the photographer will have to think fast to keep Kagura out of the enemy's hands.

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!

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.

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?

Betrayal is in the air. As Saiga fights for his life against a ruthless Euphoric posing as a friend, Kagura is attacked by the one who was supposed to cure her. Meanwhile, on a stage littered with corpses, Ginza discovers the blood-stained roll call of Suitengu's club members, finding a shocking name on the list.
