The Toughest Guy in School Is an Omega!?

By law, all omegas in this society are forced to wear chastity belts, but a persistent rumor has ignited widespread chaos: a master key capable of unlocking them exists somewhere. As factions clash in a desperate hunt for this prize, Sashima has earned a fearsome reputation as the most formidable delinquent in school. His intimidating status eventually draws the attention of the Snakes, an elite syndicate of alphas who arrive seeking a confrontation. Their leader, Aoda, anticipates facing a towering brute, but the reality leaves him stunned. The fierce fighter standing before him possesses piercing, defiant eyes, yet is surprisingly short—and secretly an omega. Rather than backing down, Aoda boldly declares Sashima his chosen partner and immediately pulls him into a forceful kiss, proving himself utterly unpredictable. This reckless act drags Sashima’s loyal right-hand man, Taketora, directly into the escalating turmoil. With tensions rising over the legendary key and Aoda’s wild advances, the story centers on a single burning question: who will ultimately be the one to break through the defenses of the toughest omega around?
