Ok First things first. I don't own Naruto nor any of the characters besides my oc. (My OC has Sasuko as her name so please don't get confused.)
I know this is a little short but its really only descriding the stuff I didnt feel like typing out twice. my other chapters will be longer I promise.
LEAF is a hospital and a medical research lab that was built many years ago by Senju Hashirama. Hashirama had also started a top secret organization for the government under the cover of the hospital. The organization was also called LEAF but they were government spies, assassins, and interrogators. The Leader of LEAF is called the Hokage. The Hokage is the top agent passed down through generations. After the Hokage is the rest of the agents as goes; Jounin, Chuunin, Genin, and Trainees.
The story I'm about to tell you takes place around a few young Jounin that was sent on a mission that was so unusual it startled them all.
