Not gonna lie, I totally wanna see Trigger do a complete reversal like this if only for an OVA XD

In history, the Axis faction was defeated during World War 2, Japan being hit by multiple nuclear weapons. However, when Japanese generals defied the orders of their emporer to surrender, and lead the armies of Japan to ignite civil war, similar uprisings began across the world, splitting nations and killing millions in a series of conflicts more deadly than the war before it. These conflicts continue to this very day, with weapons technology continuing to develop at an alarming rate.

A family risen through hardship rose to take the throne of Honnouji Acadamy, leading it with the goal of raising chaos, providing materials only to those who can take it, though still maintaining the classroom enough to teach. The leader of Honnouji Acadamy is none other than Ryuko, a girl knowledgable with a powerful set of secret weapons, as well as a short temper, both of which she uses to heavily discipline those that defy her rules.

Satsuki has transfered over from another school, looking to get revenge for her father's death, as well as to bring order and peace to a school purposefully brought to the brink of anarchy. Through organization, and careful planning, Satsuki intends to overthrow Ryuko's tyranny, and ultimately, kill her for her crimes.
