The Ironbloods and their commander are back at full strength after working with the Sakura Empire, but with the Sirens occasionally dropping by to see how things are going the line between enemy and ally is blurred. Amongst this a threat begins to rise, one that even the all powerful Sirens fear and one that may spell the end for the Ironbloods as they know it, and it's already on their front porch.

The Ironbloods are finally being pulled into the war between the Azur Lane and the Crimson Axis after the Eagle Union nearly killed the commander. Even with new tricks up their sleeves it's hard to escape what happens beyond the front lines as the Crimson Axis does it's best to defeat their enemy.

The alliances have been broken ever since the Sirens got beaten back, but with the Azur Lane and the Sakura Empire at each other's throats the Ironbloods have been left in the sidelines for the most part. It almost seems like the German shipgirls and their commander can take a rest and kick back, for now. (This is not associated with my Azur Lane series)
