Ep. 10: Yuuji confronts his white-haired doppelganger and defeats Oslo before the girls return to Mihama Academy.

Yuuji infiltrates Oslo’s vessel, neutralizing guards while Agnes and JB work on the bomb. Inside, Kazuki deactivates the Thanatos System and discusses her feelings with Amane. On deck, Yuuji battles Du Pont, a white-haired lookalike claiming kinship, who uses a performance-enhancing drug. Yuuji eventually matches him and wins. Exhausted, he reaches Oslo, who draws Asako’s katana. Yuuji dodges until disarmed, then stabs Oslo with a pen. He removes the wrist bomb with Oslo’s key and escapes the exploding ship after seeing Asako. Two years later, the girls live on Yuuji’s island. Makina collects eggs, Sacchi fishes, and Amane returns from the mainland. JB and Chizuru join them, announcing Mihama Academy’s new building is ready. Yuuji, recovering from his injuries, declines rejoining the new organization. Yumiko urges him to live for everyone. The group poses for a photo. In the final scene, Kazuki reveals her metal arm is a toy, disappointing Chizuru.
