Naruto : Tsunade, You're Really Drunk - Chapter 447: Changes in the Nature of Immortal Arts, Letter from Jiraiya

When I opened my eyes, I wasn’t just in another world—I was in another body.Specifically, the cursed husk of Dominic Nocturne von Morningstar—exiled demon prince, son of a murdered Demon King and a sleeping Demon Queen, and the world’s most powerless noble.Why? Because as a child, Dominic was betrothed to the Seven Daughters of the Seven Satans—supposedly weak, discarded girls. To seal the deal, a forbidden contract drained him of every drop of talent and sin affinity... and gave it all to them.Now, each girl commands a monstrous Sin—Wrath, Greed, Lust, Gluttony, Sloth, Envy, and Pride.And every one of them is dangerously obsessed with me.But what they don’t know is:I’m not the original Dominic.And I have a secret they must never learn—A cheat-like system has awakened inside me: The Lucifer System.A path to reclaiming my powers, rewriting fate... and maybe even dethroning the Seven Satans themselves.That is—if I can survive my psycho wives, hellish quests, and a world that wants me erased.
