The series, which consists of 20 volumes, was published by Media Factory under their MF Bunko J label from October 25, 2003, to February 25, 2015.

[2] Funimation has licensed and dubbed the anime series in English with their in-house production voice cast and released it on home media in 2012.

The episode starts with three members of different factions listening to a special newscast about an alien message, the first part of which has been translated to mean "coming to play".

Later, during a memorial service for one of his ancestors, Kio Kakazu finds a cat-like alien sitting at the buffet table.

Kio's startled cry and fall from his bed wakes her up, and she heals his hangover and minor head injury with a handheld device.

Eris, along with other ranking Catians, wearing stereotypical school swimsuits, negotiate with the Japanese government, due to misinformation on Eris' part[citation needed] Later, while the robotic servants are on guard duty and Manami and Aoi are bathing together, one of the robots is abducted by members of a yet unknown faction.

The episode opens on the Saitama Super Arena filled with members of Underside of Kitten Paw, a fanatic group obsessed with cats.

When Kio wakes up, he walks in on Eris dancing and being abnormally energetic due to having smelled silver vine spirits, an Asian plant reported to be stronger than catnip.

The girls infiltrate the set and rig the boat with real weapons, but they are caught by Kawasaki, who contracts them into his film.

Upon hearing this, Eris' hormones go berserk and she assaults Kio, something she has done several times earlier anytime something one has said sounds similar to romance or sex.

Meanwhile, Aoi wants to practice cooking to impress Kio, but due to her frequent failures she wastes a lot of food.

Chaika takes them to a virtual room on board the mothership, where they can fulfill their respective desires without it bothering anyone.

She also makes it a point that the Catia without mates use it to satisfy their sexual desires during heat and offered if they would like to try it out as well, much to the girls' embarrassment.

Manami asks for a shooting gallery with a wide assortment of weaponry, and for an M134 Minigun in particular, which turns out to be too heavy for her to lift.

He confesses that he once had feelings for her, but when he heard she was hanging out with Jack (unaware this was her female CIA handler), he thought she was already dating someone and she ended up being just a friend.

Meanwhile, a group of Dogsian Assist-a-roids are robbing surrounding areas of electronic equipment, due to their inability to self-repair.

Suddenly, a young girl named Ichika appears, and at the same time, the camp gets attacked by the Dogsian Assist-a-roids.

Kio and friends are visited by Lawry, the first Assist-a-roid created by the Catians, who came to fulfill the last wish of her creators, who died while trying to reach Earth 1000 years ago.

The Dogsians feed misinformation causing all world rockets to be suspended for a planned attack on the ship.

Kio and the others set off to abandoned launch base in Russia as part of their plan to aid their friends in space.

After Eris, Manami, and Aoi finish off the Dogsian fleet, the command ship crashes into its own orbital base, causing it to plummet to Japan.
