Keroro Gunsou

Sergeant Keroro arrives on Earth as the leader of an advance platoon sent by Planet Keron to prepare an invasion. His glorious conquest ends almost immediately when Fuyuki and Natsumi Hinata discover him inside their home, confiscate his powerful Kero Ball, and learn that the Keronian fleet has abandoned his unit behind.

Forced to live with the Hinata family, Keroro gradually reunites with the rest of his eccentric platoon: Tamama, Giroro, Kururu, and Dororo. Their plans to conquer the planet continue, but model kits, household chores, friendships, rivalries, and their own incompetence sabotage them with remarkable consistency. The longer the aliens remain among humans, the harder it becomes to tell whether Earth is still their target or simply the home they never expected to find.
