Purimura sacrifices herself in order to save the world. But Shu's strong desire to protect Purimura stops Purimura's power from activating. Shu "Merges" with Blue Dragon once again and fights Rudolph with the fate of the human race at stake.
Rudolph reveals his true goal. He wanted to collect data on all of the incomprehensible actions that Shu and the others took during his trials. He needs the information to help the Legion of Elite Species thrive.
Shu and the others see Rottarace being put on trial. As everyone is unsure of what to do, Purimura tells Shu that they should save her. Upon hearing this, Doctor Tarkovsky objects, saying that they cannot risk falling into an enemy's trap.
Shu and the others vow to defeat Rudolph. The Legion of Elite Species' defense system attacks their ship. Shu and Marumaro retaliate with their shadows, but they struggle because of the sheer numbers of their enemies.
Shu and his friends are saved by Vermillion's life-risking actions. In order to prevent his desire of overcoming fate from going to waste, Nöe heads to Zmey, and Bouquet and Marumaro set off to save Kluke.
