~~~
A long, long time ago, there was a school filled with vicious, terrifying delinquents. Its name was Ishiyama High.
Everyone in this place was a delinquent. Not just your average troublemaker either—they were feral. And to top it off, the school didn't have any teachers.
But… that was a whole one second ago.
"Being a teacher is easy. First thing to do is walk around the classrooms, check the place out."
"Then I just say 'self-study,' find a place to nap, and boom, job done. Couldn't be simpler."
Kazuma stepped into Ishiyama High's main building. After a single glance around, he couldn't help commenting: "This place is even more trashed than our guild headquarters. Graffiti everywhere, broken glass all over the floor."
The school was covered in crude drawings, shattered windows, and students dressed like they'd escaped from a bad action movie.
Kazuma had barely taken three steps down the hallway before—
"Hey. Kid. What year are you?"
"Never seen your face before."
"You're not one of us, are you? You some spy sent by another faction?"
Within moments, three or four delinquents had completely surrounded him.
"Huh. This feels familiar."
Looking at their hostile faces, Kazuma felt a strange sense of déjà vu. Honestly, he saw this exact scene every single day.
Crack.
Bang!
Bang!
He didn't even wait for them to finish talking. Three punches. All of them went flying straight out the window.
"Oh, right. This is just like home. No wonder everyone in our guild acts like delinquents."
Kazuma didn't spare those flying delinquents a second glance. It was only the third floor. They wouldn't die.
"You bastard, starting a fight without warning!"
"This guy doesn't know the rules at all! Teach him a lesson!"
"Go get him!"
The nearby delinquents saw their buddies get launched and instantly lost their temper. They grabbed whatever counted as a weapon and charged.
The next second, something almost legendary happened.
Down below, a group of first-year delinquents crouched outside smoking suddenly found people raining from the sky and crashing into them.
"Hey! You blind or what? If you're gonna jump off a building, do it somewhere else! You landed on me, asshole!"
One of them looked up at the third floor... And froze.
"What… what the hell is happening up there?"
His jaw dropped. One after another, more bodies came flying down like someone upstairs was emptying the building by throwing people out.
When the third floor ran out, the second floor started. Then the first.
In less than ten minutes, nearly every student in the building had been thrown out.
"What… what's going on inside?"
The guy at the entrance swallowed hard. It felt like something terrifying was lurking inside that building.
"It… it was some guy I didn't recognize!"
"He's super strong! Super scary! I was literally crouched in a corner minding my own business and he punched me straight out the door!"
"I had it worse! I just finished using the bathroom, didn't even say a word, and boom—sent flying!"
The delinquents groaned in pain where they'd landed. Honestly, these kids were tough. Dropped from the third floor and they were only complaining that it hurt.
Tap. Tap. Tap.
Footsteps echoed from inside the building. Everyone still conscious snapped their attention toward the entrance.
"You didn't know me before, but you should know me now."
Kazuma stepped out. "Name's Kazuma, your brand-new teacher. For the next four months, this school is my turf."
"When I say one, nobody says two. If I tell you east, nobody even thinks west."
"And if anyone dares disobey…"
He flicked his fingers. The stone pillar next to the door exploded into powder.
"Relax. I'm not gonna kill you. At worst, I'll break every bone in your bodies."
He smiled kindly. Honestly, these delinquents weren't that bad. Way easier to handle than Natsu and the others.
"Now stand up straight and look this way."
His warm smile instantly twisted into something ferocious, and the pressure rolling off him hit like a demon roaring inside their heads.
"Y-yes, sensei!"
They jumped to their feet. They couldn't help it. Even their hair was standing on end.
"Good. And why are those guys still lying on the ground? Are they mocking me?"
Kazuma frowned down at the unconscious students. "I tell you to stand and you lie down? What, feeling bold because you know I won't kill you? Maybe I should take one out as an example…"
"Sensei, wait! Maybe… maybe they haven't gotten up because you broke their bones or knocked them out… you know… with that punch?"
A trembling student slowly raised his hand.
"So fragile? I didn't even use one percent of my strength. Kids these days need to stop messing around and start working out."
Kazuma shook his head. He really hadn't hit them hard. If they passed out that easily, that was definitely the result of too much hand exercise.
"Sensei, should we call an ambulance?"
One of them stared at a friend foaming at the mouth. It felt wrong not to.
"No need. They're alive. Let them sleep it off."
Kazuma glanced at them. Looked fine to him.
"Anyway, I just came to say hi. Head back to your classrooms."
He waved casually and walked off to continue checking for any students he hadn't thrown out yet.
Once he was gone, the delinquents finally snapped.
"That guy is seriously a teacher? He's not here to teach. He's here to rule us!"
"Is he even human? He crushed a marble pillar with a finger flick!"
"What does he mean 'I'll try not to kill you'? That's a damn threat!"
They couldn't take it anymore. Sure, they'd seen strict teachers before, but who the hell hires someone like that?
Did the principal bring back a teacher or summon some final-boss demon?!
"No way. We gotta fight back. If we don't, we're gonna be ruled like this forever!" Someone stood up and shouted.
"Yeah! There's a ton of us! No way we can't beat him together!"
"He's strong, but he's just one guy. He has to run out of strength eventually!"
"And when he does, we'll take him down!"
There was a moment of hopeful silence.
Then someone quietly muttered: "Um… guys… I don't think we can beat him."
"Yeah. He threw everyone on the third floor out the window in, like, a minute."
"I don't know how much strength he used… but we're already lying all over the ground."
Everyone looked at the unconscious bodies scattered around. Then someone whispered the question none of them wanted to ask: "Can we win?"
"Win my ass. We'll be lucky if we don't knock ourselves out trying."
"Don't lose hope! All our top guys are out today. And once the Tōhōshinki come back, they'll definitely drive that teacher out!"
"Right. Everyone's off fighting the guys from Gintama High. That teacher's only acting big because we're shorthanded."
"Once our people return tomorrow, that guy's getting flattened."
"..."
"O-okay but… can someone call an ambulance first? I feel a tiny bit like I'm dying over here…" One of the guys on the ground grabbed a friend's ankle and croaked weakly.
The friend instinctively kicked him off and only afterward realized what happened. "Don't grab my ankle out of nowhere! You scared the crap out of me."
"Cough… cough…"
The injured delinquent stared at him, heard those words, and got so furious he spat blood and passed out on the spot.
The enemy couldn't defeat him… but getting betrayed by a teammate was too much.
"Shit, he's dying! Call an ambulance already!"
"That teacher's insane. And that was him holding back. What would he do if he actually meant to kill us?"
"One punch and we'd be vaporized!"
The group scrambled to call emergency services while checking if their friends were still alive.

"What a peaceful day. Look at the students helping each other. Wonderful."
The principal, pruning plants in a totally ignored corner of the campus, watched the chaos fondly.
Truly peaceful, he thought. Hiring this teacher was absolutely the right decision.
Just then, Kazuma poked his head out of a window and yelled. "Hey! Did you not hear what I said? I told you to get back to class."
"What? You want me to throw you in myself?"
"Sorry, sensei!"
One look at Kazuma's eyes and the delinquents backed down instantly. They glanced sadly at their injured friends. It hurt to leave them behind, but survival came first.
"Bro… my brother… don't go…"
One of the guys on the ground whispered dramatically.
"Sorry, bro."
The friend didn't hesitate even a little. He marched straight back to class without looking back.
"Bro my ass…"
The injured one spat in disgust. At least pretend to hesitate. If it were me, I'd look back at least once. Can't believe I called you my bro.
...
Everyone returned to their classrooms. Kazuma began his rounds with the first-year classes.
"Good. Self-study."
He glanced at students who hadn't even opened a book, nodded as if satisfied, and walked out.
"This teacher is really this half-hearted?"
"Wait. All he said was to return to class. He didn't say what we had to do in class."
"So we can do whatever we want as long as we stay in the room!"
The students immediately relaxed. And once they relaxed… well, the inevitable happened.
"Hey. Did you step on my foot just now?"
"It was your weird foot sticking into my space!"
"Oh yeah? You wanna fight about it?"
"Come on then. I'm not scared of you."
By the time Kazuma finished checking every classroom and returned to the principal's office to rest, full-on brawls had broken out everywhere.
"This chair really is comfortable…"
Kazuma leaned back, planning to sit there, convert natural energy, and burn through the rest of the day.
But soon the principal returned.
"Um… that's my seat."
He stared at Kazuma sitting in his chair and spoke in a tiny voice.
"What?"
Kazuma looked up.
"N-nothing, sir. It's just… sensei… if possible, could you at least pretend to be, you know, teaching? Maybe sit in a classroom for a bit during class hours?" The principal asked very carefully.
"Fine. You're the client. You call the shots." Kazuma stood up and headed out to find a classroom to lounge in.
The principal exhaled with relief. "Thank goodness. Sensei is reasonable."
He sat down and was just about to relax when Kazuma suddenly came back in.
"S-sensei? Is there something else?"
"No. The classroom doesn't have a chair, so I came to borrow yours."
Kazuma picked up the principal's chair and walked right back out.
"Uuuu…"
The principal stared at his disappearing chair, empty inside. He was starting to think he had invited an even bigger problem into the school.
---
Meanwhile, in a certain first-year classroom—
"Why did he suddenly come to our classroom!"
"Is he targeting us?"
"Everybody shut up. Sit straight. Smile. Don't look at him. Don't give him any excuse to beat us."
The entire class sat perfectly upright like model students, terrified he'd find a reason to smack them.
[Ding~]
[Task request from Tohru.]
[Task description: 'Uh, I'm currently being stabbed by a god's sword and about to die. Not totally sure what's happening but help would be nice.']
Kazuma was half training, half scrolling on his phone when the request popped up. Not from another world, but from this one.
"Alright. Got something to do. You guys self-study. If the principal asks, tell him I went to the bathroom."
He thought for a second, decided the kids would live, and got ready to leave.
"Yes, sir!"
Everyone answered at once. Finally. He was leaving. Holding that perfect posture for this long was torture.
...
Kazuma left the school and followed the address from the request until he reached a mountain forest.
Deep inside, he found a massive green dragon.
"A human? What are you doing here?"
Tohru stared at the unexpected visitor, confused why a human would appear this deep in the mountains.
"Tohru, right? Pretty sure I found the right dragon."
"I accepted your request. Now let's talk payment."
Kazuma looked up at the dragon, thinking dragons were too valuable to pass up. He planned to charge a premium.
"Y-Hmph! Humans really are greedy creatures. So it was you who asked me to make a request."
Tohru snorted. She hadn't expected anyone to actually come save her. And when the one who arrived was human, she expected even less.
"If I work, I get paid. That's normal. Call it greed if you want. Every living being has desires. If you don't, you're probably dead already."
"If I pull that sword out, you give me some dragon blood or dragon scales or whatever. How's that? Good price, right?"
He wanted to study dragon materials. Dragons had always been legendary creatures. Who knew what he might discover?
"A mere human? You think you can pull out this divine sword? Your mind would collapse the moment you touched it."
Tohru didn't believe a word he said. To her, he was just another human blinded by greed.
"I'll take that as a yes. Since we agreed, let's begin."
Kazuma summoned his floating magic cannons, switched them to gravitational mode, and yanked the sword out without even touching it.
No hands needed. Just pure force.
