Life seems simple enough for Koichi, a Japanese middle school student, until he learns that he is the reincarnation of an alien protector who crash-landed on Earth millennia ago and that he has now been given the mantle of responsibility as "the defender of the Earth", Koichi/Babel then teams up with three super-powered alien companions to battle the the dark forces of an evil cult leader. The war to save humanity takes Babel from the jungles of Southern Asia to the Upper East Side of Manhattan and, ultimately, to a final battle with "the Master" at a hidden base in the Swiss Alps. The action is both fast-paced and deadly. The fate of the world rests in the ability of this courageous youth to both control his latent psychic powers and use them to defeat the enemies of mankind.
