Bestowing Falna on the Kunoichi

I had survived. Somehow, I'd passed the graduation exam. As Iruka-sensei handed me my ninja headband, I felt a wave of relief so pure I almost cried. Finally, I was a shinobi of Konoha. My life was about to begin.And then, right before my eyes, a semi-transparent blue window appeared.[Soul Synchronization Complete. Welcome.][System: Falna Activated.]I blinked. Then I blinked again."What the...?"Before I could even finish the thought, a tsunami of another life crashed into my brain. Twenty-five years of existence in a world called "Earth." Anime, manga, video games, internet forums, and above all, an unnervingly encyclopedic knowledge of the lives of every single person around me.My life. The life of Naruto Uzumaki. A story I had watched on a screen.The shock was so intense I almost threw up my lunch ramen. My first kiss was with Sasuke! I saw it on a monitor, and now I have the first-person memory! And that's not even close to the worst thing that's going to happen to me!I looked at the crowd and saw Hinata Hyuga, shy and adorable. That's when my attention returned to that word floating in my vision. Falna. The system gave me a brief, horrifying explanation. I could turn people into fantasy heroes, boosting their abilities to absurd levels. It was the perfect tool to change the future.There was just one small, tiny, incredibly problematic detail about the activation ritual.My eyes landed on Hinata again, who blushed instantly."WHO THE HELL DESIGNED THIS POWER, A DOUJIN AUTHOR!?"My path to Hokage is no longer about hard work. It's about exploiting my Otaku knowledge, surviving puberty a second time, and convincing the strongest kunoichi to let me... "update their status."Sounds way better than "drawing on their backs."
