Travel through Naruto, become an orphan of the Sarutobi clan, and activate the [Ninjutsu Modifier]. Others' Ninjutsu is learned, and his Ninjutsu is modified. Fireball too slow? Change attributes and become Thunder Escape, doubling your speed. Is the Chidori too noisy? Defects are deleted silently and consumption is halved. Rasengan not strong enough? Add wind escape and use the spiral shuriken twenty years in advance. The Third Hokage: "It took me ten years to realize this theory..." Sakuya (inner): Actually, I just changed the value. In order to investigate Danzo, he was forced to repeat the grade for three years and became a well-known bad guy in the school. The daily tasks are: pretend to be weak, take advantage of others, and secretly protect Naruto. Until the Kingdom of Waves, Naruto was in danger, and he took action for the first time—— Kakashi: "Who are you?" Sakuya: "A student who doesn't want to graduate."
