For Renton, every day's the same, and the only thing that keeps him happy is lifting on his ref board. Until one day, a giant mecha called an LFO comes crashing
down on him, and inside is the most beautiful girl he has ever seen! The thing is, the girl is on the run from the military with her stolen mecha. Renton will have to summon up all his courage to face his childhood hero, get the girl to like him, and live up to the legacy of his father who saved the world. But hey, at least it's not boring anymore.
