Rikujou Bouei-tai Mao-chan

In order to protect Japan from a mysterious alien invasion, the Defence Force Team (DFT) has been assembled.

But these are no ordinary heroes.

They are all grade school girls, who most of the time cause more trouble than good.

But why did the Defence Party (DP) even bother to assemble this overly cute team?

Apparently, it is because the chief of the DP, Onigawara Rikushirou, has his granddaughter placed on the DFT.

Onigawara Mao (ground defence), Tsukishima Misora (air defence) and Maruyama Silvia (sea defence) make up the DFT, and when they combine forces, they can unleash a great power.

Together with Mishima Kagome, the team's commander, can they really fight against the mysterious aliens?
