Teaching in Naruto: The System Says I'm Tsunade's Student

[Congratulations Host, you have reached six years of age. The Strongest Hokage Development System has been activated.]

[Mission 1: Become Tsunade's disciple and form the New Sannin with your classmates Naruto and Sasuke.]

"What kind of idiotic system is this? I'm already twenty-one years old, and Naruto and Sasuke are my students. How am I supposed to become Tsunade's disciple? Answer me!"

[Mission 2: Help your deskmate Hinata Hyuga retrieve her scarf.]

[Mission 3: Vandalize the Hokage Rock with your classmate Naruto Uzumaki.]

[Mission 4: Defeat Sasuke Uchiha and dominate the Ninja Academy.]

"I'm a teacher at the Ninja Academy. Are these missions appropriate? I'd rather jump off here than do them!"

[Mission Rewards: Creation Rebirth, Konoha Whirlwind, Super Beast Imitation Drawing, Dark Cloak Jutsu.]

"System, you win! I am indeed a genius who just turned six! Deep Blue, add points! Let me see your limits!"

Kitazawa, a three-no's (emotionless, speech-less, expression-less) transmigator, an unremarkable Chunin, in order to survive until the finale, he lay low teaching at the Konoha Ninja Academy. It wasn't until he turned twenty-one that a problematic system appeared, and from then on, the ninja world would no longer be peaceful.

ps: Lighthearted, invincible style. Two excellent books already exist: <Lurking in Konoha, Part-time Hokage> <Konoha: Gu Master Creates Hokage>. Welcome to collect and read.
