Ground Defense Force! Mao-chan (陸上防衛隊まおちゃん Rikujō Bōetai Mao-chan), also known as Earth Defender! Mao-chan, is a 4-volume manga and 26-episode comedy anime, created by Ken Akamatsu.


On the edge of an invasion, the world's defense has fallen to unlikely straits due to the aliens being excessively cute. Due to combat engagements being televised: if the forces battling the aliens were not cute themselves the general public would revolt, as it would be seen as "bullying". Consequently, three military leaders chose their granddaughters, Mao, Misora and Sylvia, to be the defenders, fittingly, becoming a team even cuter than the aliens. The story follows the three eight-year-old girls as they try to defend the Earth against the invading aliens.




A game called Ground Defence Force Mao-chan was created and released on the 23rd of January, 2003, for the PlayStation 1 in Japan.
A "Raising Simulation" the player is tasked with raising Mao-chan as they would like to increase the Defence Cabinet's approval rating as she battles cute aliens intent on invading Earth.
Boasting 90 different abilities and the voices of the original cast from the anime, the player is given the opertunity to defend famous Japanese locations and to uncover over 10 alternate endings.
