Near the new port of Marseilles, France. Riku finally awakens from a coma and everyone is overjoyed. But Riku is anxious about the way his body feels. Something is different. Worried about his little brother, Kai is frustrated about not being able to help him in any way. In the mean time the Schiff is about to reach the Red Shield HQ after Saya.

Kai begs Saya to give her blood to Irene and save her from the advancing crystallization process. But Saya hesitates: what will she decide in the end?

In the meanwhile, in the Red Shield HQ, Julia continues her researches, but she notices that her mentor Collins has got in touch with an unexpected person...

It's a beautiful day, and Saya invites Hagi, Riku and Kai for a walk in the streets of Paris. It had been a long time since they enjoyed a peaceful time. But Kai is not comfortable and distances from Saya. Riku tries to go between the two, so that the three could restore their former relationship.

Moses leaves to get what was demanded in return for Diva's blood: Kai's life. Moses does not realize James' real intention and takes a sword alone.

James comes to see Solomon who was gravely injured by Diva and is confined. James, intending to bring despair to all of mankind, declares to Solomon that he would eliminate Saya. Meanwhile, David with Kai and others start an operation to stop the live broadcast of Diva's opera performance around the world.
