Elric was just an ordinary guy—until fate threw him into the chaos of the Marvel Universe, right in the middle of war-torn Sokovia. In a world where the rich gain power through cutting-edge technology and the poor are left hoping for a lucky mutation, Elric had no advantages. No money. No powers. No way out. But everything changed one morning when he awoke in a mysterious white space—and met alternate versions of himself, each from a different world: Overlord, Naruto, One Piece, Solo Leveling, and more. Somehow, their souls were all fragments of the same origin—and they could share powers across realities. With their strength now flowing into him, Elric saw the path forward. In a world of gods and monsters, he would forge his own fate—not by relying on destiny, but by connecting every version of himself across the multiverse. After all, if no one else will save him... He’ll become the one who saves himself.

Born into the Hyūga clan without the Byakugan, Haruki should’ve lived in the shadows — a forgotten branch on a sacred tree. Instead, his chakra began to change. Not in the eyes… but everywhere else. While Neji is called a genius and the clan clings to bloodline pride, Haruki's power blooms in silence — sharp, strange, and undeniably different. It bends space. It senses emotion. It shouldn’t exist. And no one knows what it really is. But the clan can feel it. The elders whisper. The stares grow colder. And Haruki? He’s done being silent. Set in the heart of the Hyūga compound, this is a story about bloodlines, rebellion, and the quiet rage of a child born wrong — or maybe just born different. -------------------------- Disclaimer: I don’t own Naruto or One Piece — those masterpieces belong to Kishimoto and Oda respectively.
