Y/n Kuroshima was once Y/n Sakura-a mundane boy with an ordinary life, a loving family, loyal friends, and a sweet romance. Then, his world shattered like brittle glass. Senior year became a living hell. Ruthless bullies targeted him daily. His friends ghosted him, cowardly preserving their fragile social status. Worst of all, his lover cheated on him with his chief tormentor. When he turned to his family, they chose the lies of monsters over their own blood, isolating and neglecting him.
Broken and alone, Y/n realized a dark truth: the world is inherently cruel, a theater where people use malice to shield their hollow insecurities and fragile egos. When diagnosed with a terminal illness, he didn't weep; he smiled at the sweet promise of release.
In a final act of absolute defiance, Y/n exposed his tormentors' dirtiest secrets to the world. Then, standing before the family that abandoned him, he burned his belongings to ashes. He handed them his medical records, spat crimson blood at their feet as final proof, and disowned them. Ignoring their sudden, pathetic pleas, he walked away into the cold silence. He let the sickness consume him, dying alone in a dark alleyway.
But fate refused to let him rest.
In the abyssal void, his righteous malice summoned the legendary sword, Ankokuken Kurayami. Recognizing his dark truth, the blade chose him. Reincarnated into a new world with a powerful new body, he discarded the fragile Sakura name forever. He forged himself anew as Y/n Kuroshima-a man who writes his own destiny with blood and shadow. No longer a helpless victim, he wanders the realms as a legendary Dark Knight. To the corrupt, tyrannical, and evil, he is a cold, ruthless, and merciless executioner. To the weak, innocent, and forsaken, he is a chivalrous, deeply honorable savior. The dark warrior has risen.
