I remember reading this a while back, but I can't remember what was the name of the story. It was a Female MC fanfic. A war was going on between konoha and someone else and she become famous by defending a forest. (Genjutsu ~ adding screams, making trees look horrifying, adding skulls and corpses everywhere) from a lot of pursuers.
it was fanfiction.net, pretty sure with that. I just remember the scene where she slaughtered and scared to death an army of some kind and got her Fame from that (Maybe even S-rank bingo) On another note, there was one other fanfiction im having trouble finding, another female MC , where MC became famous with Ogre nickname i think (also i think she lost one of her arms, not sure tho)
