Koichi stumbles into godhood like a kid who inherited a house he doesn't want, armed with alien roommates and a job description that makes no sense. The plot careens from deserts to Manhattan to secret bases with the logic of a fever dream, treating world-ending stakes like they're background noise while occasionally stopping to wonder if Leon actually has feelings. It's absurdist sci-fi that doesn't know it's absurdist sci-fi, which makes it exactly what it needs to be.

Koichi lives an ordinary student life until he discovers he is the reincarnation of an alien protector, and with that comes the role of Earth's defender. Taking the name Babel, he joins forces with three alien companions who have powers of their own to fight the dark forces of an evil cult leader. Their war to save humanity carries them from the deserts of southern Asia to Manhattan's upper east side, and on toward a confrontation with the cult's master at a secret base hidden in the Swiss Alps. Koichi's psychic power lies dormant within him, and he must learn to control it if he hopes to defeat humanity's enemies. The action comes quickly and the fights are deadly, in a sci-fi adventure with supernatural and mystery elements.
