简介：在某个名为NP的城市，警察厅遭投诉最多的是战车队，尤其是其中一辆名为“布拿巴力”的特别战车。“布拿巴力”是为了适应城市作战的特殊需要而制造的坦克，体积超小，甚至可以通过窄小的门驶入建筑物内，动作机动灵活，同时装备完备，配有能发射穿甲弹的主炮、速射机枪、烟雾弹、催泪弹、AA GUN make by whyarmy以及一些不知名的东西，连钩状履带都是特制的（用来破坏路面吗？）。操作这辆坦克的是被称为警署的炸弹组合的本作主人公莉安娜和亚路，面对罪犯，他们总是能够机敏勇敢地将其捕获，不过总是会对环境造成巨大的破坏（怪不得会有这么多投诉）。
简介：The story of the movie is somewhat based on the plot of the most recent game, Sakura Wars 3, released back in March this year. While the game features Lieutenant Ohgami, the main character who takes off for Paris, narrates one side of the story, the movie unveils the secrets behind Hanagumi. Ohgami leaves for Paris, consequently leaving Hanagumi without a leader; thus a new character will be introduced here. To be replaced with Lieutenant Ohgami is the former leader of Hoshigumi, Rachette Artile - a rationalistic and distinct individual, who brings about serious problems to Hanagumi. The members are now in discord with Rachette. Meanwhile, Teikoku Kagekidan was being threatened by some irrelevant demons and a new type of anti-kouma mechas, (brought by an american company) appears and tries to replace the koubu-kai. Having made repeated mistakes due to the absence of Ohgami, Hanagumi is now faced with an unprecedented danger, while the abolishment of Teikoku Kagekidan Hanagumi is being schemed.
