Naruto's Uchiha girlfriend is too Tsundere

Reincarnated into the world of Naruto and became Uzumaki Naruto himself! I thought I'd have to walk the same path as the original underdog's rise to power, but right from the start I awakened the [Bond System] - as long as I form connections with canon characters, I can gain opportunities to grow stronger! Flying Thunder God Technique? Learn it! Wood Release? Master it! Sage Mode? Perfect it! And secretly... WAIT A MINUTE! SASUKE IS A GIRL!
