Ep. 20: Akiha Bangun di Dalam Kotak Saat Masa Hidup Honoka Berakhir dan Nami Ditikam

Aboard Xanthippe, Akiha wakes up inside her box, with Imo-chan still trying to get her out and Leopard still searching for her. After Akiha's friends return from an unsuccessful search, they decide that Akiha must be in Kirkwood. However, Honoka collapses soon after, and reveals that her lifespan is nearly over. In the meantime, Kazane talks with Leopard, discussing how they can find Leopard's last three parts. When Benkei shows up to challenge Leopard again, Kazane successfully negotiates with Tsutsuji for the pair to retrieve the Proxima Crown for Leopard. The student council approaches Kazane, asking to be allowed to infiltrate Kirkwood, and Kazane links them up with Itsuki, while Honoka goes to talk to Professor Fon on Earth. Back at Kirkwood, Nami, Aleida, and Takane encounter a spybot from the UURE while stamping out the resistance, which attacks Nerval and steals information from him. They manage to destroy the spybot as it tries to escape, but Nami is stabbed by it and falls to the ground. (Source: Wikipedia)
