Waking up one day, I found myself reincarnated via fetal transmigration into the world of Naruto, born into the same generation as Naruto and Sasuke. This was undoubtedly a hellish start. Fortunately, at the age of one, Izayoi awakened the Talent Entry System. By defeating opponents, there's a chance to acquire their talent traits. As a starter pack, the system granted one opportunity to copy a talent trait. Upon receiving this benefit, Izayoi's first thought was to use it on Naruto to copy his Sage Body. However, struck by a flash of insight, Izayoi abandoned this thought. He decided to use this precious copying opportunity on Toneri Ōtsutsuki, who had supposedly come to Earth with his father to secretly observe Hinata. In this world, where the entire narrative essentially revolves around Ōtsutsuki family conflicts and bloodline reigns supreme, no 'cheat' or external power-up could be more powerful than a pure Ōtsutsuki bloodline.

In the swirling currents of time and fate, one soul was cast into a world it was never meant to be in. Karl D. Sephiroth-a name unknown to history, yet one that would soon shake the very foundations of the world. He is not a pirate. Nor a marine. He is a time traveler-an outsider who gained the Batto Batto no Mi Devil Fruit at the wrong time... and in the wrong place. With a power that blurs the line between life and death, Sephiroth seeks only one thing: A peaceful and beautiful life in this chaotic and disordered world of One Piece. But this world does not allow anyone to live in peace so easily. Position? Justice and evil? "The winner is the king... and the loser is just a bandit." In these seas, it is not principles that shape history-but power. Justice and evil are mere concepts... privileges that belong to the victors. And Sephiroth? He has no problem being called a hero, as long as he is the one who wins. Those who have witnessed his existence say: Boa Hancock, Pirate Empress: "Sephiroth... as long as you wish, I will do anything for you!" Kozuki Hiyori, Princess of Wano: "For the sake of our master, Brother Momonosuke... I beg you, die!" Sengoku, the Legendary Admiral: "I could never tell if Sephiroth is a righteous man... or not." Monkey D. Dragon, Leader of the Revolutionaries: "Friend... could you help me revise the revolutionary program of this world?" Sora Cyborg, Supreme Commander of the World Government: "This man... Sephiroth... he is truly insufferable!" And so... begins the story of a man who refuses to follow the tide. A victor who rewrites the meaning of 'justice' with his own hands.
