第 22 集: 秋葉與一樹從納瓦利斯特手中逃脫,同時穗乃果綁架了方,眾人從廢棄工廠營救受創的箱人。

Akiha is rescued by Itsuki, but the student council ship is pursued by Nervalists and forced to take shelter in Kirkwood. The UURE, which has taken over the moon, is planning another attack. However, their plan is interrupted by Nerval, who appears and freezes the whole moon. On Earth, Honoka gets Fon to come with her by hitting him with a bowling pin and kidnapping him. Akiha can't come to grips with Imo-chan being gone, but she, Itsuki and the student council find a box human factory and meet up with one of the Shishido elders. He leads them to a box human disposal factory, where they rescue people pretending to be dead and bring them to a hiding place inside Kirkwood. However, many of the rescued are deeply traumatized and long for their boxes. Xanthippe discovers and attacks them, and is about to prevent their escape when Benkei rams her. With prompting from Tsutsuji, Benkei further helps the rebels, along with Takane, who has broken Nerval's control. Benkei escapes with everyone on board and jumps to the Innsmouth Reef, where they see Leopard. (Source: Wikipedia)
