Gordian Warrior

The Earth has turned into a barren wasteland, and the remaining survivors struggle to rebuild their lives. Daigo Otaki, a young orphan raised by his uncle, grows up unaware of his past. When he comes of age, he learns that Victor City was designed by his late father, a brilliant scientist, and is now managed by his sister, Saori. She urges him to accept his inheritance-a powerful super robot system called Gordian. Daigo joins the Mechacon mechanic combat 18th regiment, a team of law enforcers tasked with protecting Victor City from the threats of the Madokuta organization.
