The OVA strips away every narrative excuse and builds something pure: two machines designed to fight, fighting, with nothing underneath but the physics of their collision. What could have been toy commercial noise becomes an almost meditative study of what combat actually costs, frame by frame. The animation treats each impact like it matters, not because the stakes are dramatic but because the violence itself is the entire point. Most mecha shows use fighting as punctuation. This one is content to let you watch metal bend and servos scream for a single episode, then stop.
