Led into an illegal mission against a military ally, Armored Trooper Chirico Cuvie stumbles upon a secret his government would do anything to hide: the body of a beautiful woman suspended in a capsule of energy. For this discovery, Chirico's superiors leave him to die in the hands of enemy troops. He escapes with his life, but is forced to flee to the criminal haven of Uoodo City. Here, amid the outlaws and beggars, Chirico begins his galactic quest for justice!

After the fall of Uoodo City, renegade Armored Trooper pilot Chirico Cuvie travels to the jungles of Kummen where he signs on as a mercenary in a bloody civil war. When he discovers the guiding hand of the sinister Secret Society behind the conflict, Chirico is swept up in a whirlwind of battles that not only reunite him with Fyana, but also bring him face to face with his deadliest opponent yet: Ypsilon, a fierce Perfect Soldier with a score to settle!

After their escape from the Kummen Jungle Wars, Chirico and Fyana find themselves trapped on board a space battleship bound for the war-ravaged planet Sunsa with Ypsilon and the Secret Society hot on their heels. Unable to alter their course, they fight a desperate running battle, but soon discover that Sunsa's burning, airless deserts are no safe haven.
