After being betrayed and murdered by his first girlfriend, Yuma Amano—revealed to be the fallen angel Raynare—Issei Hyoudou awakens in a void. There, a voice offers him a chance: accept the Tyranny System and carve his own destiny, unbound by the manipulations of gods, devils, or angels.
With the Boosted Gear still within him, and Ddraig’s soul watching over, Issei accepts. He is reborn, but not as the same perverted boy. Now cold, calculating, and haunted by betrayal, Issei begins a journey not just of revenge, but of domination—one where he will stand above all pantheons.
