After Reycho saves his friends, Pielope attempts to start another game, but Pai renounces it on behalf of the mastermind hidden among them, before being hit by a debris.

After escaping the underwater amusement park with a submarine, the class arrives at Kagoshima and Pai manages to restore her memory.

They reunite in Shikoku, where they meet the Master of a cult dedicated to a powerful artificial intelligence called MAIK, while being pursued by the damaged Pielope.

After the incident of Kyoto and Osaka, the group meets the people at the cave, and learn the existence of an Otherworlder opposing MAIK and X-TYPES.

Reycho, rebuilt by MAIK as a defense mechanism, attacks his friends, but their group's song causes him to be self-aware and disable the core barrier.
