What if a Cold, Six Eyes Issei Conquered DxD? (Harem)

What happens when the ultimate cursed technique enters the world of Devils and Angels? In this massive crossover "What If," Issei Hyoudou is not a pawn to be controlled. Instead, he awakens with the legendary Six Eyes and a boundless well of cursed energy. Stripped of his usual fiery demeanor, this new Issei is cold, calculating, and views the supernatural hierarchy of High School DxD as nothing more than a flawed system waiting to be dismantled. With his devastating "Infinite Boost" Domain Expansion, he effortlessly crushes the Chaos Brigade and terrifies the Great Satans. But even an absolute conqueror builds an empire. As Issei tears down the old world order with clinical precision, he draws the loyalty and deep affection of elite women—foremost among them the fierce, protective matriarch, Mikoto. Together, they forge an unstoppable alliance and a powerful harem, rewriting the rules of the Underworld forever. Will anyone in the Three Factions be able to bypass the infinity that surrounds him, or will this cold-blooded prodigy rule supreme? 🎬 Written and Directed by: Me (If you are enjoying this serialized What-If, make sure to smash that like button, drop a comment, and subscribe so you don't miss the next chapter!)
