Teaching at the Ninja Academy, but the System Thinks I’m Tsunade’s Student

【Congratulations, Host has reached the age of six. The Strongest Hokage Training System has activated.】 【Mission 1: Become Tsunade’s disciple and form the new Legendary Sannin alongside your classmates Naruto and Sasuke.】 “What kind of brain-dead system is this?! I’m already twenty-one! Naruto and Sasuke are my students! How the hell am I supposed to become Tsunade’s apprentice?! Answer me!” 【Mission 2: Help your deskmate Hinata Hyuga retrieve her scarf.】 【Mission 3: Graffiti the Hokage Rock together with your classmate Naruto Uzumaki.】 【Mission 4: Defeat Sasuke Uchiha and dominate the Ninja Academy.】 “I’m a teacher at the Academy! Does any of this sound remotely appropriate?! I’d rather jump off the Hokage Monument than do these quests!” 【Mission Rewards: Strength of a Hundred Seal, Leaf Whirlwind, Super Beast Imitating Drawing, Bringer-of-Darkness Technique.】 “…System, you win.” “I am absolutely a once-in-a-generation six-year-old prodigy.” “Deep Blue, allocate points! Show me your limits!” Kitazawa was the definition of average: no clan, no bloodline, no talent. Just an ordinary transmigrator who clawed his way to Chunin rank and spent his days hiding safely inside Konoha’s Ninja Academy as a teacher, all to survive until the end of the story. Then, at twenty-one years old, a completely broken system finally arrived. And from that day onward, the ninja world was never peaceful again.
