Konoha: Coaching in a Ninja School and Was Mistakenly Identified as a New Student by the System

Hinata's scarf was snatched away by an upperclassman, and she huddled in a corner crying. Uzumaki Naruto wanted to invite him to go graffiti at Hokage Rock, but the ANBU kept him from coming close. Uchiha Sasuke even directly questioned in class - "You alone are worthy of being my teacher?" Kitazawa clutched the system panel, and the six-year-old certification and the main mission of "Ruling the Ninja School" were flashing crazily. He is an official teacher of the ninja school, not a kid who just entered the school. But those rewards - the Yin Seal, the Konoha Whirlwind, the Super Beast Fake Painting - every line of words was eating away at the last of his sanity. After all, living is more important than anything else in Konoha. Moreover, the system only required him to "become a squad leader" and did not say how many years he had to be. As long as you operate it properly and get past the mission, you can still wait until the finale safely. As for Hinata's scarf, Naruto's recognition, and Sasuke's challenge, Kitazawa has his own way. Those tasks will be completed sooner or later, but the method used will probably make the entire Ninja School confused. This novel and its characters are purely fictitious.
