Ground Defense Force! Mao-chan

Ground Defense Force! Mao-chan, also known as Earth Defender! Mao-chan, is a 26-episode comedy anime, created by Ken Akamatsu, the author of Love Hina. It stars three eight-year-old girls, Mao, Misora and Sylvia, as they try to defend the earth against invading aliens. The world's defense has fallen to unlikely straits because the aliens are excessively cute, of which combat engagements are 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 to be the defenders, fittingly, becoming a team even cuter than the aliens. They each have a clover-shaped badge that enables them to transform. The series itself is rife with parodies and references, particularly to Akamatsu's earlier work Love Hina. The girls' commanding officer bears a resemblance to Naru Narusegawa from Love Hina.
