Akiha awakens inside her box on Xanthippe while Imo-chan attempts extraction and Leopard continues searching. Her friends conclude she is in Kirkwood after a failed search, but Honoka collapses and reveals her lifespan is nearly over. Kazane discusses finding Leopard's remaining three parts with Leopard, then negotiates with Tsutsuji for Benkei to help Leopard retrieve the Proxima Crown. The student council asks to infiltrate Kirkwood, so Kazane connects them with Itsuki while Honoka speaks with Professor Fon on Earth. Meanwhile, Nami, Aleida, and Takane fight a UURE spybot at Kirkwood that attacks Nerval and steals data. They destroy the bot, but Nami is stabbed and falls.
