Naruto: I Died Nine Thousand Times and Scared Hinata to Tears

I transmigrated into Naruto as Yagetsu Makoto, a civilian orphan, and Mizuki was about to silence me from the start? [Ding! Host's death detected. The ultimate life-saving System, “Records of Observation,” has activated!] [Core ability: Rewind ten minutes!] The first time I died, a giant Shuriken pierced me. Agony! The second time, a kunai slit my throat. I couldn't breathe! After the hundredth death, I looked at Mizuki, still shouting threats, and smiled. [Rewind activated! Enemy weakness highlighted: an old injury to the left ankle joint!] The next second, I landed an “accidental” kick and pulled off a perfect counterkill, stunning the Third Hokage! From then on, the ninja world had a monster in its midst! Zabuza's Silent Killing Technique? [Death Rewind x10] I know the fog better than you do, even with my eyes closed! Orochimaru's Forest of Death? [Death Rewind x100] I mapped out the perfect sightseeing route and cleared the place while picking up a few extra rewards! Pain's Shinra Tensei? [Death Rewind x1000] I know exactly where your real body goes to the bathroom! Kakashi: “H-He always predicts my predictions. How?” Third Hokage: “This boy isn't a genius. He's a walking disaster, Konoha's greatest treasure!” After dying nine thousand times, I looked back and saw the entire ninja world trembling beneath my feet!
