Lime-iro Senkitan

Synopsis

In the 37th year of the Meiji Era (1904), during the Russo-Japanese war, the small Japanese army receives aid from a special flying ship, the Amanohara—kept aloft thanks to a benevolent demon—and uses it to strike at Russia's key base in Port Arthur (Lushun). Umakai Shintaro, a Japanese-born Russian diplomat, defects and travels to Sapporo to teach at a girls' academy. But this academy is far from ordinary: it is located aboard the Amanohara, and the five girls he instructs form the Raimu Unit—young women capable of summoning powerful beings to fight on their behalf. Shintaro soon becomes both their teacher and their battlefield commander, and the six of them set off on a strange and excessively erotic journey. Along the way, Shintaro helps the girls overcome their weaknesses, grow stronger for the final showdown at Lushun, and come to understand the motives behind the "Russian Spiritual Corps" that aids the enemy—a corps that, unfortunately, includes a member Shintaro once knew well...
