Sakura Wars

The year is 1921, and this is a Tokyo where monstrous steam-powered robots crash a flower-viewing party only to be cut down samurai-style by a young girl in a kimono and traditional hakama pants. It's eight years after the horrific Demon War, and Japan is a peaceful prosperous place. Meet Ensign Ogami Ichiro, who has just graduated from the Naval Academy. He's assigned to a base in Tokyo, but soon discovers that his headquarters is the Imperial Theater and his first mission is collecting tickets at the gate. He gamely goes about his menial jobs at the theater, surrounded by beautiful girls who seem to know a lot more about what's going on than he does, but he's about to be swept into a roiling world of robots, demons, and hot girls in uniform.

With the Hive of Darkness and High Priest Tenkai defeated, peace has returned to the capital thanks to the Imperial Combat Troupe. But a new enemy has risen and threatens to disturb this new year of peace! The curtain is rising, the bells are ringing and a new battle is about to begin, for the Kouma have been resurrected by their new King: AOI SATAN
