Koutetsu no Vendetta Episode 0

Synopsis

After several years in the military, Rain Yashima has grown impatient and frustrated. The Japanese army was not going on the offensive at all, and there was an overwhelming difference in the level of weaponry between them and the enemy army, the Seventh. At this rate, it would only be a matter of time before they lost the war, let alone overturn their inferior position.

Then a ray of hope landed on Rain's doorstep. In her hands is the power to judge history, and in her hands is the power to weave history. The girl abandons her womanhood and vows to fight as steel. Now, Yashima Rain's lonely war begins.
