In the year 192 according to the All‑World Calendar, humanity stands on the brink of extinction. The Orbital Ring, composed of a colossal number of artificial satellites, has been occupied by incomprehensible alien life forms – the radams. People who find themselves on Earth"s surface, as if in the palm of a hand, cannot escape the lasers of the Orbital Ring. Fields have gone barren and cities are destroyed. The United Forces of Earth"s Defense cannot cope with the enemy. Earth inexorably moves toward its demise. Yet, from nowhere appears "Tekkamen‑Klinok" – a nameless, memoryless, past‑free man bound in armor, alone doing what no army on planet Earth can accomplish.
