The population has placed its stakes on a reckless organization in hopes that it can purify the planet for environmental growth. But the organization known as Z.P.T. fails tragically. Many humans are transformed to white sand. Was this massacre an accident, or does Z.P.T. hold some dark intent for the unfortunate inhabitants? In this post-apocalyptic future three buxom young women - Liza, Wooty, Mill - and one fortunate young man, Louis, use their mechanical prowess to fend off waves Z.P.T.'s superior mechanized military forces. Guns and mecha mix with humor and plenty of "fan-service" in this original manga adventure.
