Note:- Return by Death, Harem, few r18 scenes, few disturbing assaults scenes.“I died... and died... and again and again and again,” Alan roared, sitting atop a pile of corpses, arms outstretched, gesturing at the war-torn landscape filled with bodies—all his own, each killed in a different way.“Can I tell you the tale of Alan Fitzgerald?”“How his family betrayed him, how an entire nation hunted him and how he hunted them back.”“All because he wasn’t blessed by those damned twelve gods.”In this world, people who reach the age of 12 will undergo the ceremony called Rite of Ascension, where they'll be blessed by any of the 12 gods.Their blessings determine the future of them.Alane Fitzgerald was the first heir of the Fitzgerald dukedom. Everyone believed that he would be the next chosen champion of the Sun God. Everyone believed that; even Alane believed that.Everyone loved him and cherished him.Until.On his 12th birthday, he undergoes the Rite of Ascension. Something went wrong, clearly wrong. None of the 12 gods didn't choose him; they didn't give him champion blessings, not even common or uncommon blessings. Worse than that, he was marked as a cursed devil.He was thrown into prison by his own parents, mocked by his own younger brother, and finally he was sold as a slave.He wants revenge; he wants to kill everyone who broke him and wants to make them suffer, even the gods who mocked him, but he is powerless.Then he met something dark, which offered him revenge. Gave its own blessings to him.Rather than blessings, it's a curse, yet it'll give him a chance to kill everyone.
