Konoha's Life Mentor

The air in the Konoha Ninja Academy office hummed with the distant shouts of children.
Kanda Kyoichi, a young man with weary eyes, slumped in his chair, the rough fabric of his Chūnin vest scratching against his skin. Just weeks ago, he'd been on the frontlines at Kikyo Pass, staring death in the face. Now, bandaged but alive, he was assigned to teach ninjutsu to a class of energetic kids.
"Seriously? An intern teacher?" he muttered to himself, running a hand through his spiky hair.
The ninja world was brutal, and his current strength as a mere Chūnin felt woefully inadequate. Survival seemed like a distant dream. As the class bell rang, signaling his next lesson, a strange, ethereal voice echoed in his mind.
[Activating Mentor System…] [Activation complete!]
Kyoichi froze, his eyes wide. A system? In Konoha? Could this be his chance?
