Seeing Leopard, Nami is stunned, and when Akiha races towards her, Nami commands the Nervalist forces to retreat. Seeing his chance, Benkei separates from Leopard, and steals two of Leopard's mirrors before escaping. Akiha, Honoka, and Itsuki meet with Elle and Emilio, who decide to transfer as many people as possible to Leopard's colony. Due to the Existence attack, Leopard is still unable to connect to his colony, so Akiha tries to cheer him up, but fails. With pressure from Elle and advice from Itsuki, they hold a party to cheer Leopard up. After the party, Leopard and Akiha share a private moment looking up at the Earth and the Moon, and have a heart-to-heart talk. Akiha shows Leopard that everyone is encouraging him, and Leopard is able to connect to his colony again just as Xanthippe attacks. He successfully fights her off with the Leopard cannon, but in the aftermath, Akiha is kidnapped by Aleida.
In the year 311 of the Orbital Calendar, humanity has migrated to countless colony clusters in space. A space colony girl named Akiha Shishidou encounters a malevolent artificial intelligence named Leopard that has been installed on a colony.
