From F-Class Trash to Mech God

In a wasteland world, F-class mechanic Rayne is betrayed by his fiancée and a wealthy heir, left to die in a Zerg swarm. After accidentally ingesting Zerg blood, he survives and gains mutated, superhuman abilities. The Empire's Goddess of War, Valeria, proposes a contract marriage to escape a royal arrangement. Using his genius mechanic skills and unprecedented mecha synchronization, Rayne crushes his former abusers at the Global Mech Tournament. Facing the Zerg Queen's mind control and the corrupt Empire elites, he pilots the forbidden S-class mech "Adjudicator" alone into the Hive. Ultimately, he breaks the mind control, slays the Queen and saves humanity, rising from F-class trash to the ultimate Mech God.
