Ground Defense Force! Mao-chan

Mao Onigawara is an 8-year-old grade-schooler and the granddaughter of the Chief of Staff of Japan's Ground Defense Force. Alongside her friends, who are the granddaughters of the Chiefs of Staff for the Air and Marine Defense Forces, Mao prepares to defend Japan against an invasion by "cute aliens." These extraterrestrial beings are too adorable to be fought with conventional military tactics, creating a unique defense challenge.
