Yuusha Party kara Tsuihou sareta kedo, EX Skill "Kotei Damage" ni Muteki no Sonzai ni Natta

Chrome once stood as the mage of the legendary hero’s party, fighting shoulder-to-shoulder against the Demon Lord’s legions. At his side were those he trusted most: Irina, his beloved betrothed, and Yuno, the celebrated hero and his closest friend. To Chrome, their bond was unshakable—a fellowship forged in battle and sealed in mutual devotion. Yet that camaraderie existed only in his own heart. Behind his back, Irina had grown far too close to Yuno, and the two conspired to sever Chrome from everything he held dear. In a calculated act of betrayal, they drained him of his magical power, sacrificing his potential to elevate the hero's strength, and cast him out of the party like refuse. Left powerless and alone, Chrome was soon cornered by a swarm of demons on the very battlefield he once helped protect. With death closing in and despair swallowing every glimmer of hope, something dormant deep within him began to stir. In that abyssal moment, he touched a forbidden "darkness" that had always lurked beneath his gentle exterior—and from that void, an unparalleled skill awakened. Now armed with an absolute ability that renders him invincible, Chrome rises from the ashes of his humiliation. No longer a discarded pawn, he sets his gaze upon those who ruined him, ready to turn his unyielding power into the instrument of his long-awaited retribution.
