Megumi to Tsugumi

When alpha male Megumi hears about a masked man with an iron pipe and a killer glare attacking people, he knows this spells trouble. When he summons the man in question, Tsugumi Yamada, the fearsome delinquent who appears crackles with hostility. Just when they're raring for a fight, omega pheromones drift to the alpha, bewildering him. That's when Tsugumi smugly says the unthinkable: the pheromones are coming from him! An omega is shocking enough, but for an omega to pick a fight while in heat, and without using any suppressants!!? Tsugumi's existence baffles Megumi. He's determined to do something about the heat. Bring on the unprecedented omega problem child!
