The JSDF, UN, and Efy Dolgh search for Muetta. Yukina's class decide to go to Toyama Memorial hot springs at “Kenshin’s hidden residence” for the weekend. Not all end up going, only the core group of Yukina's friends. Meanwhile the wounded Muetta takes refuge at the hot springs, hoping to aid her recovery. After getting lost, Yukina and Kennosuke arrive at the same spring, where they stumble upon Muetta, and the UN takes her into custody. Just then, a Cactus unit appears, captures Yukina, and escapes back into orbit.
