“Kill…!” “Kill…!” The voice echoed endlessly in his mind—a chilling whisper from a past he could never escape. Back when he was nothing more than a living weapon, forced to fight as a slave, that voice was his only companion. Kento Shinkawa, an amateur mixed martial artist burdened with ten consecutive losses, couldn’t shake the relentless whispers or the disturbingly vivid dreams that plagued his nights. They weren’t just memories—they felt real. Sometimes, without warning, an uncontrollable surge of fury would consume him, igniting a primal instinct to destroy. In those moments, Kento would fight like a cornered beast, pushing his opponents to the very edge of death. But when he managed to rein in that storm, his raw talent shone through, and he tore through his competition like a wildfire, rising swiftly to become an undeniable force in the ring. Yet, the world outside the cage was just as brutal. Greedy promoters and shadowy figures circled him like vultures, eager to exploit his growing fame for their own gain. But Kento wasn’t alone—friends and allies stood by him, ready to shield him from the darkness both around him and within. The shadows of the martial arts world began to collide with the darkness in Kento’s soul, setting the stage for a clash that would change everything.
