Based on the original work by Akamatsu Ken the creator of Love Hina, produced by Xebec the studio who brought us err.. Love Hina.In order to protect Japan from a mysterious alien invasion, a defence force team has been assembled. But there are no heroes, not even look-alikes. They are all grade school kids and most of times they cause more troubles rather than doing their job. But why did the defence party even bother to assemble this cute defence force team? Ssst.. It's because the chief of defence party, Onigawara Rikushiro, has his granddaughter placed on the defence force team.Onigawara Mao (ground defence), Tsukishima Misora (sky defence) and Maruyama Silvia (marine defence), the three of them make up the defence force team and they all look alot like cute miniaturize Love Hina characters. When the three of them combine together, they can unleash a great power. Add Mishima Kagome as the commander of the team, can they really fight against mysterious alien?
