Teaching at the Hokage Academy, the System Says I'm Tsunade's Student

【Congratulations, Host, you have turned six. The Strongest Hokage Development System is now active.】 【Mission 1: Become Tsunade’s student, and join your classmates Naruto and Sasuke to become the New Sannin.】 “What kind of stupid System is this? I’m already twenty-one. Naruto and Sasuke are my students. How am I supposed to become Tsunade’s student? Answer me!” 【Mission 2: Help your desk mate, Hinata Hyuga, get her scarf back.】 【Mission 3: Graffiti 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 really appropriate? I’d rather jump off a cliff than do them!” 【Mission rewards: Yin Seal, Konoha Whirlwind, Super Beast Imitating Drawing, Bringer-of-Darkness Technique.】 “System, you win! I’m a genius who just turned six! Deep Blue, assign my points! Let me see what you can do!” Beize, an emotionless transmigrator and an utterly ordinary Chunin, keeps his head down and teaches at the Konoha Ninja Academy so he can survive until the finale. Then, when he turns twenty-one, a glitchy System arrives, and the ninja world is never peaceful again. P.S. A lighthearted, invincible-hero story. The author already has two highly acclaimed works, Lurking in Konoha, Working as a Part-Time Hokage and Konoha: The Insect Master Builds a Hokage. Add them to your collection and give them a read!
