What Is Keroro Gunso☆ About?
The story follows Sergeant Keroro, a frog-like alien from the planet Keron who arrives on Earth with a mission to conquer the planet.
However, Keroro's invasion plan does not go as expected. After being discovered and captured by Fuyuki Hinata and his older sister Natsumi Hinata, Keroro is left behind on Earth after the main Keron forces abandon him.
Instead of conquering Earth, Keroro ends up living with the Hinata family while continuing to dream about completing his invasion mission.
The result is a comedy-filled story involving Keroro, his platoon members, the Hinata family and the strange situations created by their everyday life on Earth.
