Ryo, a poor orphan in Konoha and a distant descendant of the Senju, is mocked for his red hair and lives at the bottom of the academy. One day, he awakens his cheat. His first inheritance: the iron-blooded physique and combat legacy of Red-Haired Shanks from the world of One Piece.

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.

To become Hokage, Naruto won't just train - he'll rewrite his fate one simulation at a time. When the line between reality and simulation begins to blur, what kind of shinobi will he become?

After the Fourth Great Shinboi War, he lost everyone, his precious friends, his lover, and the world that was counting on him? He failed to protect the only thing he was tasked with. Now, Naruto finds himself haunted by the "what-ifs." Thoughts racing of: What if he could save those who were lost? What if he could change the course of history for the better? What if... He could travel to the past? In this fanfic, the future Naruto is mute. ⚠Warning, Contains: Yaoi, mentions of blood, PTSD, and explicit language.
