The Mastermind Behind Konoha's Folklore Museum

Li You was a die-hard anime fan. After staying up all night binge-watching the latest Naruto special, he rubbed his aching temples and yawned. The moment he reached for his pillow, a blinding white light enveloped him. When he opened his eyes again, he was standing at the checkpoint by Konoha's main gate, wearing a faded Chunin vest. The name tag on his chest clearly read, “Li You, Konohagakure, Land of Fire, Chunin.” He had just finished absorbing the original owner's memories of being ambushed by Stone Shinobi, collapsing from exhaustion outside the village, when the three members of Team 7 returned from the training ground carrying a freshly picked watermelon. Sasuke Uchiha glanced at him sideways, Naruto Uzumaki bounced over and stuffed the watermelon rind into his hands, and the Medical Ninjutsu scroll in Sakura Haruno's grasp swayed back and forth. The original owner was a dead-last who knew only basic taijutsu and the Three Body Technique. Li You had arrived at just the moment when the Uchiha Clan was about to be wiped out. Relying on his thorough knowledge of the plot from his previous life, he hid in an alley behind the police force's back entrance on the night Itachi went to speak with Fugaku, using the excuse that he was covering a shift for a fellow guard. There, he happened to see Shisui, wearing his forehead protector, surrounded by Danzo's men. He pulled out the flash bomb the original owner had hidden in his pocket and slammed it onto the ground, then grabbed Shisui by the wrist and ran with him toward the secret passage in Shisui's home. He managed to drag Shisui back from the brink of death, saving him from the fate that would have awaited him in Danzo's scheme. With Shisui secretly backing him up, Li You used his Chunin status to slack off in the supply office and stockpile resources. Thanks to his knowledge of the plot, he gave Sasuke a protective talisman against the curse mark before Orochimaru had even set his sights on him. On the day Pain attacked Konoha, he led the elderly and women and children to a backup air-raid shelter behind Hokage Rock ahead of time, drastically reducing the village's casualties…
