The blooming battle between Saya and the other Progress comes to an end, and the result drives a wedge between Saya and Amane.

Saya and the others are heading to the Red World, Terra Rubiri Aurora, to check on the Ouroboros, but Elel's best friend, Ramiel, is waiting for them. Ramiel asks Elel if they're really friends.

Nya figures she has to move after seeing Saya and the others deepen their bonds, and heads off to the Green World on her own. But an army of Ouroboros stands in her way.
