Girls that have been dubbed the "Progress" are those who have awakened to the superpower "Exceed". These girls, from the five different worlds that exist, are kept safe and trained day and night with their alpha drivers at Seiran Academy.

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

The girls have to deal with the aftermath of the Ouroboros attack. Their fighting power has greatly reduced, and they soon find out that things are worse than they had feared when some of the members are corrupted by the darkness.

Saya and the others are to make their way to Darkness Embrace, the Black World. They have confirmed that the energy "Extra," important to the worlds, is being lowered there. They are ordered to investigate, but someone’s there waiting for them.

Almaria is a vampire with a complex that stops her from sucking blood because she's too embarrassed, and Sofina keeps inviting Almaria to suck her blood. Almaria is faced with a dilemma. On one hand, she respects Sofina, but on the other.

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.
