Naruto: I am a Teacher

Satarou Kazuma was quite irritated. 25 years ago, he was reincarnated as an ordinary orphan in the Naruto world. He had no choice but to become a ninja. And he didn't want to become a canon fodder if he became a ninja. But sadly, he wasn't a genius like Kakashi, nor a training maniac like Guy. He ended up becoming an ordinary jonin, barely surviving in the Third Ninja War out of Genin Corps. Still, he worked hard, not like Guy, but he did! And he was atleast a strong Jonin now, after Kakashi and Guy in his age group. He wanted a relatively safer job than being a Jonin, that is being a Jonin-sensei. And now, he became the Jonin-Sensei of Hinata-Kiba-Shino! Now, he will make monsters out of them.
