The SSS-class hero "Queen of Thunder" Angelina loses her husband to drug lord Silco and goes into hiding to raise her son Odinson. An F-class user, Odinson awakens to SSS-class power at eighteen. He applies to the Hero Academy but is disqualified after his stepsister Liz falsely accuses him of using illegal enhancers, so he turns to the underground fight ring. Together with his mother, he fights off the Nival family's hunters and uncovers the truth: Silco murdered his father, shielded for years by former Association deputy chief Sterling Nival. When Silco takes three hundred students hostage, Odinson walks in as the decoy, defeats him, and saves everyone.
