Naruto: I'm a Teacher, But the System Thinks I'm Naruto's Classmate!

Kitazawa—a classic time traveler with no cheats, no bloodline, and no background—managed to survive as a mediocre Chunin for over twenty years by keeping a low profile and being a teacher at the Konoha Ninja Academy.

Just when he thought he could quietly live out the rest of his life in peace… a system activated.

[Congratulations to the Host for turning six. The Strongest Hokage Training System is now online.]

“…Wait. Six? Me? You’ve got the wrong guy! I’m 21!”

Worse still, the system’s tasks were anything but normal:
[Task 1: Help your deskmate Hinata retrieve her scarf.]
[Task 2: Graffiti the Hokage Rock with Naruto Uzumaki.]
[Task 3: Defeat Uchiha Sasuke and dominate the Ninja School.]
[Task 4: Become one of the Three Great Ninjas besides Naruto and Sasuke. Workship Tsunade as your master.]

"Tell me—how is a 21-year-old supposed to do these kinds of tasks with a straight face?! I’d rather jump off the Hokage Rock!"

[Task Reward: Uzumaki Bloodline, Senju Bloodline, Yin Seal, Konoha Great Whirlwind...]

…Well, it’s not impossible.
