A nine-year-old kid with a clay robot that falls apart every other episode is somehow still the only thing standing between a dying god realm and total collapse. Wataru doesn't learn life lessons or grow into a hero, he just keeps showing up because no one else will. This OVA doubles down: more missions, the same kid, the same ridiculous stakes, and absolutely no safety net.

Wataru Ikusabe, the boy who was magically carried off to Soukaizan, the realm of the gods, in the original series, is called into action once again. The story is set a few months after that first adventure. Across two OVA episodes, this continuation mixes action, adventure and comedy with fantasy and mecha elements, keeping the franchise's blend of humor and giant robot battles.
