A kid finds out he's a reincarnated alien guardian and has to immediately start saving the world with three superpowered strangers he just met. The OVA format means this thing moves at sprint speed, no filler, no time for doubt, just one collision after another from desert to Manhattan. By the final episode you've either bought into Koichi's sudden cosmic responsibility or you haven't, and the show doesn't care which.

Koichi's ordinary life as a young student shatters the moment he discovers the truth: he is the reincarnation of an alien protector who crashed on Earth. Now the planet's fate depends on him awakening dormant psychic abilities he barely understands. Taking up the role of Earth's defender, Koichi joins three powerful alien companions, each carrying their own supernatural gifts. Together they fight the dark forces of an evil cult leader. The conflict pulls them from the deserts of southern Asia to Manhattan's upper east side. The stakes escalate toward a confrontation at a hidden base in the Swiss Alps, where the enemy known as the master waits. Speed and violence define every encounter, and Koichi must master his latent power to defeat humanity's enemies.
