Kio Kakazu meets a girl with cat ears at a memorial service, who introduces herself as Eris. The next morning, Kio wakes up with a hangover and finds Eris in his bed.
Kio springs into action when a secret organisation takes Eris captive, organising a rescue attempt, but with alien technology at her disposal, Eris isn't helpless.
Aoi and Manami take refuge in the Catian embassy after being labelled as traitors by their former organisations; an intruder attempts bath time raid.
Kio heads to Tokyo with the girls for some shopping, but a kitty-loving cult attacks their train; Manami, Aoi and the Assistroids plan a rescue.
Manami and Aoi undertake a high seas raid to free Eris and Kio from Antonia's yacht; the intense battle leaves Aoi unconscious.
Manami wants to get better at handling guns and Aoi feels frustrated by her lack of cooking ability; a virtual reality room gives people the chance to hone their skills.
