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.
