My Senju System: Wood Release & Immortal Body

My name is Naoki Senju, Tsunade's little brother, and I'm supposed to die a disposable genin in the brutal Second Shinobi War. After my sister's accidental, bone-shattering punch knocks me out cold, I wake up in a new body… to the jarring chime of a 'Strongest Selection System.' My first choice: Awaken the legendary Wood Release and an Immortal Body, just like the First Hokage! My second? Master the very 'Sea' of Water Release, wielding it with terrifying speed, rivaling the Second Hokage himself!
