Naruto: My Attribute System

Reborn into Naruto, Kato Yukaze wasn't a prodigy. Just a Chunin, watching parents die, crushing his naive dreams. Years of grueling missions yielded only minor progress. His clan's ultimate Spirit Transformation Technique, the key to unseen power, remained agonizingly out of reach. He was just another pawn in a deadly world. Then, at 22, his 'Ninja System' finally activated. No grand fanfare, just raw attribute points from every mission, every kill. This wasn't plot armor; it was a grind. Every dangerous encounter became a chance to fund his hidden growth, subtly enhancing his body, mastering jutsus, inching towards true power. He just invested a massive chunk into his physical strength, finally breaching the Jonin threshold. Can this unlock the forbidden Spirit Transformation Technique and turn him into Konoha's unseen legend, or will the world's consciousness reject his foreign soul, leaving him broken?
