Long Summary
Osamu continues to head to the base, as Hairein chases him. However, Mira, with her remaining Trion, uses her Trigger to impale Osamu in the arm, leg, and stomach. Despite being heavily wounded, Osamu throws Replica into the invaders' ship, which was their plan.

As Hairein realizes this, Yoneya and the C-Rank members shoot at Hairein. Yūma also shoots at Hairein, only for all these attacks to be blocked by Alektor. However, Miwa uses Fūjin to attack Hairein from the underground by surprise, and manages to heavily damage the Neighbor.

After being thrown into the ship, Replica manages to program it to retreat in 60 seconds. Mira goes back inside to try stopping it, only to reveal it cannot be reversed. Hairein takes the cube Osamu was holding, only to find out that it was not Chika's, deducing that he hid it in the rubble. Not having enough time to search for it, he goes back inside the ship and the group retreats, after Viza also returns.

Hairein decides they would abandon Hyuse as planned. Replica, who is on the ship, tells Osamu to take care of Yūma. The ship leaves, and the invasion is finally over, while a severely wounded Osamu lies inside a pool of his own blood, unconscious.
