Naruto: Wooing Tsunade from Day One!

"Ahem..."

With a light cough, the teacher instantly silenced the noisy classroom. It wasn't because the children were particularly obedient, but because the teacher himself looked intimidating.

He limped on one leg, and a scar stretched across his face, leaving only one eye open. As his single eye scanned the room, a wave of unease rippled through the students.

"My name is Osamu Suzuki," he began, his voice slow and deliberate, "a retired Chūnin."

His gaze lingered on each student as he continued, "Over the next few years, you will learn about the knowledge and skills of ninjas under my guidance. Most of you come from ninja clans, so I hope you won't let me down."

The deep tone of his voice echoed through the classroom. Some of the more timid children dared not even lift their heads to look at him.

This arrangement had been Kawakaze's idea—a plan to give retired ninjas meaningful work while ensuring young ninja-in-training received proper guidance. The wisdom these veterans carried was hard-earned, paid for in blood and sacrifice.

"We'll work hard," a few students murmured hesitantly.

Among them, Guy's voice rang out the loudest, startling Kakashi beside him so much that he clapped his hands over his ears. Guy's enthusiasm was palpable; he clearly admired this new Sensei, and his excitement was already beginning to boil over.

"Speak up! I can't hear you," Osamu Suzuki barked, his energy filling the room.

The startled students quickly responded in unison, raising their voices to match his demand.
