In the year 543 of the Graphic Era, on February 14th, the Revolution of '43 erupted. Triangular soldiers from Rhombus City engaged in a massive conflict with troops representing the polygonal ruling class just outside Hexagon City, with countless casualties.
Yet, the instigator of it all, the ruler of Rhombus City known as "Round A12.JPG" the Elder, vanished, causing some chaos among the soldiers of Rhombus City. Unexpectedly, however, a triangular soldier soon replaced the Round Elder, took command of the army, and began an assault on Hexagon City.
This development didn't surprise Ze. After all, he had spent a lot of effort educating these shapes, so such an outcome was somewhat expected.
Besides, the triangles had been suppressing their rage for hundreds of years. Ze had simply cracked open a door, and the floodwaters poured out, now beyond anyone's control.
