>>3355317Thirty years prior to the movie, a subset of the population turned into fire mutants, the "Burnish," and caused mass destruction. The story takes place in the new model city of Promepolis, which is under attack by a terrorist faction of the Burnish. Galo, the blue one, is a member of Burning Rescue, a firefighting mecha squadron that puts out Burnish fires. But there are also conspiracies related to the Burnish and the nature of the new world, so Galo and Lio, the blond one, have to punch a lot of stuff in and out of robots while Trigger-text flies around and people scream about their manly burning spirit.
Honestly before I looked for plot summaries I assumed it would be "Trigger does Captive Prince" based on Lio's costume, the pose in the key visual, and how fast the /cm/ threads were moving.
