Naruto: Undercurrent

A civilian orphan, a memory from another world, a ninja road paved with intelligence and perseverance. In the spring of 1960 in Konoha, six-year-old Asano Ya was queuing up in front of the registration office of the Ninja School. His mind contained the memories of the entire series of "Naruto" from his previous life, but his body only had the most ordinary civilian chakra talent. There are no bloodline boundaries, no family secrets, no chance from heaven - his only advantage is knowing what will happen next in this ninja world. The annihilation of the Uchiha clan, the collapse of the Chuunin exams, the hunt for Jinchuuriki by the Akatsuki organization, the Fourth Ninja World War - he saw the dark clouds in advance of every storm, but he only had a handful of kunai in his hand that could not be thrown accurately. What he can do is not to change history, but to be the person who "happens to be in the right place" at every critical juncture. When Sasuke became an island after the genocide, he was the first person to speak to him in an equal tone. When Naruto was struggling on the verge of transforming into the Nine-Tails, he was the one who planted the chakra sealing array at the training ground three years in advance. When Shikamaru's tactics lacked intelligence support, he was the "humble civilian ninja" who handed over a complete enemy file. **This is the story of an ordinary person coming out of an extraordinary world. There is no need to steal the halo of the protagonist, no tampering with the fate of the original work, no magic weapon coming out of thin air, only intelligence, tactics, training, and a heart that never compromises. **
