Betrayed by every being in the supernatural world, his sacred gear, the Boosted Gear, is seized and given to his brother, who is hailed as the new hope. Draig, the Red Dragon Emperor, finally feels relief, free from Issei's perceived weakness. As the world turns its back, Issei awakens to a past shrouded in pain and neglect. He remembers his childhood, tormented by his family's disdain, bullied and ridiculed in school for his perceived uselessness, and shunned by the supernatural community for being a "pervert" and "weakling." Yet, deep within him, a power older than his time stirs-Sukuna, the King of Curses, reincarnated into his very being, seeking revenge. Fueled by memories of betrayal and the burning desire to prove his worth, Issei embraces his new identity. Alongside his loyal harem. Issei becomes a formidable force of vengeance and power. No longer the hero, he will become the villain the world fears, reclaiming what was stolen and reshaping fate to make them all pay.

Issei Hyoudou, a normal student at Kuoh Academy, wielded a Sacred Gear and held the title of Red Dragon Emperor-a respected warrior despite his perversion. Yet, all of his achievements were rendered meaningless when his younger brother, Dai Hyoudou, stole his glory and accomplishments. Worse, Dai spread false claims that Issei was a fraud. Betrayed by his lovers and friends, who turned their backs on him in favor of Dai, Issei found himself alone. Worse still, the factions saw him as nothing more than a disposable tool, useful only until his purpose was fulfilled. And so, his title as a pillar of the faction was stripped away and handed to Dai. During his battle against Nyx to free Ingvild from her control, Dai seized the opportunity, taking credit for the victory and proclaiming himself Ingvild's "savior." With no further use for Issei, Dai struck him down, driving the Dragon Slayer Holy Sword, Ascalon, into his chest, seemingly killing him. But fate had other plans. From the depths of despair, Issei awakened something... something demonic. A power so terrifying that even a Devil May Cry at its presence.
