Elijah Green adjusted the brim of his baseball cap and stepped onto the cracked asphalt of Shimizu High School. The morning sun glinted off the windows, casting long shadows across the courtyard. Students milled about—laughing, arguing, occasionally running late. None of them knew a quiet storm had just arrived.
Elijah sighed. High school. Again.
He had retired from being one of the top five strongest assassins in the world. One punch could send a man flying across a city block. His reflexes were faster than anyone else could track. And yet now… he was a gym teacher.
Boring, he thought. But maybe boring was… peaceful.
First Impressions
The first-year class was already bouncing on their heels. When Elijah entered the gym, the room fell into a strange, instinctive quiet. Messy dark hair framed his sharp, observant eyes, his fitted T-shirt and dark pants hinted at raw strength underneath, and a faint dried bloodstain on his shirt—forgotten from yesterday's "incident"—caught a few students' eyes.
"Uh… Mr. Green?" a small girl whispered, pointing. "Is that… blood?"
Elijah's lips curved into a soft, warm smile. "Old mess. Don't worry about it. I didn't even notice."
Students blinked, unsure whether to be impressed, scared, or both. Somehow, his calm, approachable aura made them feel safe.
"Line up. Warm-ups first," he said, his voice gentle but carrying undeniable authority.
A scrawny boy immediately nudged a smaller student. Elijah's eyes twitched—barely. That was all it took. The boy froze mid-step, sensing the silent power radiating from their teacher.
In one smooth motion, Elijah stepped forward, grabbed the boy's wrist, and spun him over a mat, landing him perfectly on his back. Not a scratch, not even a bruise. Just a silent, precise warning.
"Lesson one," Elijah said softly. "Strength is for protection. Not intimidation. Not bullying. Understood?"
The class nodded, wide-eyed. Some whispered: He's… scary. But nice.
Chill, Lovable Teacher Energy
Elijah walked to the center of the gym, stretching casually. "Push-ups. Ten each. Don't cheat. Strength without control is worthless."
He dropped to the floor, effortlessly doing thirty perfect push-ups without breaking a sweat. His movements radiated controlled, casual power. The students stared, mouths agape. "If I can do it, you can do it too," he said warmly, helping those who struggled.
Even in exertion, he remained calm, approachable, and oddly lovable. Aiko, a mischievous first-year, whispered: "He's… scary strong, but he's also… nice?"
Elijah caught her glance and winked. "Exactly."
By the end of class, students were sweating, exhausted—but motivated. They wanted to impress him, not because they feared him, but because he made them want to push themselves.
A Casual Threat Emerges
After school, Elijah was locking the gym when three men in black suits appeared near the gates. They moved with deadly precision. Ordinary criminals? Maybe. But Elijah's instincts screamed danger.
He straightened, baseball cap shading his eyes, hands in his pockets. Calm. Chill. Friendly.
One man stepped forward. "Elijah Green. Retired, are you? Or just hiding?"
Elijah smiled faintly. "I'm just a teacher now. You might want to try chess club if you're looking for competition."
The men lunged.
Elijah didn't flinch.
One step and the first man was pinned against a wall, immobilized with perfect precision.
Another swung a metal baton. Elijah caught it effortlessly mid-air, twisted it free, and tossed it aside.
The third tried to circle behind him, only to be launched into a pile of mats with a casual flick.
All three were down, tied neatly with ropes Elijah carried in his gym bag—remnants of old habits. Not a scratch permanent, but a clear warning.
He adjusted his cap, smiling faintly. "Boring… until now."
End of the Day
The next morning, Elijah walked into the gym, calm and approachable. His aura was peaceful, his smile warm. Faint traces of yesterday's fight lingered—slight muscle strain—but no one dared to question him.
Aiko grinned. "Mr. Green, how are you so strong… but so nice?"
Elijah smiled softly. "Strength is meaningless if you can't control it. Protect, teach, inspire—that's what counts."
Every student wanted to do their best. Not out of fear, but out of respect and admiration.
Elijah Green was a walking paradox: insanely strong, deadly when needed, but calm, chill, and utterly lovable. High school might be boring… but for Elijah, it just got interesting.
