Synopsis
In the future, humans are mining asteroids for resources. A young boy named Nanbu Ushiwaka, the first child born in space, lives on an asteroid called Tortatis with other colonists.
Their relatively peaceful existence is shattered when a military operation goes wrong, causing a major disaster during an attempt to capture Halley's Comet.
Stranded and abandoned by their company and country, Ushiwaka and the colonists face a desperate fight for survival. They must find a way to escape the asteroid before its nuclear reactor melts down, threatening their lives and their only home.
