『サクラ大戦 奏組』アニメ化決定！！単行本1巻にDVD付属

大神一郎远赴法国担任巴黎华击团的队长之后，帝都花组迎来了新团员——前星组队长拉奇特(ラチェット·アルタイル）。拉奇特的个人主义作风与花组重视合作的做法形成强烈对比，双方摩擦不断。剧情的主线在于军方试图以新研发的无人驾驶蒸汽机取代花组，令花组陷入了解散危机。

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.
