The time is the early 1920s and Tokyo is menaced by an invasions of demons. To combat them, Kanzaki Heavy Industry has developed robotic battle armour powered by spiritual energy. Sumire Kanzaki, the arrogant granddaughter of the owner, is the first candidate to control the armour successfully. She's joined by karate champion Kanna Kirishima, sharpshooter Maria Tachibana, diminutive blond psychic Iris Chateaubriand, Chinese gadgeteer Ri Kohran, and sword fighter Sakura Shinguji to form the Imperial Floral Assault Unit. The threat of the demon invasion falls by the wayside as the girls get involved in theatrical productions that somehow increase their spiritual energy. The arrival of their first male commander, Ichiro Ohgami, a comic cute guy adds a little sexual tension. The fight scenes are brief, and the first big battle between the mecha and the enemy sees each of the girls surrounded by lots of enemies.
