In a world where the legendary Seven Deadly Sins are scattered and branded as traitors, a mysterious boy named Ver lives as an outcast feared by all. Born on a night when time itself stopped, he possesses the Eternis Eyes (永劫眼, Eikōgan) and an endless reservoir of magic known as the Paradox Core. With the ability to see countless futures and bend the flow of reality, Ver is a living anomaly capable of overturning fate itself. When Meliodas begins reuniting the Seven Deadly Sins to save Liones Kingdom, he reveals a secret eighth member: Ver, the Sin of Eternity. At first distant and burdened by years of fear and isolation, Ver slowly finds something he has never known before—trust, companionship, and a place among them. As the threat of the Ten Commandments and the ancient Holy War resurfaces, Ver’s power becomes central to the war’s outcome. His ability to slow time, predict every outcome, and erase enemies across all possible futures makes him one of the strongest beings in Britannia—feared by demons, goddesses, and even fate itself. But overwhelming power comes with a burden. Ver must choose whether to remain an existence beyond time, detached from the world itself, or embrace his humanity and fight not because destiny demands it, but because he chooses to protect those he cares about. The Sin of Eternity is a fantasy tale of loneliness, belonging, and a boy who was never meant to exist—yet becomes the one who shapes the future of the world.
