Space Emperor God Sigma

Synopsis

By the year 2050 AD, humanity has made great strides in space technology. Suddenly, a mysterious enemy emerges: the Eldar, who come from 250 years in the future. In their timeline, specifically 2300 AD, Earth invaded their home planet, Eldar, and defeated them using the formidable Trinity Energy, a mysterious power source far more powerful than a hydrogen bomb. The Eldar seek to seize this Trinity Energy before it can be used against them. They begin by capturing Io, one of Jupiter's moons that serves as a human colony. Next, they launch an assault on Trinity City, deploying their Cosmosaurus forces to secure the Trinity Energy. Toshiya and his companions take to the skies in their God Sigma to protect Earth and the Trinity Energy, sparking a long, drawn-out battle to reclaim Io.
