Miu cackled as she finished tightening a screw. At last, after all this time, all the work and testing, it was done. She was putting the finishing touches on what was probably her most amazing invention yet.

With that done, she set down the screwdriver and picked up the gun, which in its design, almost appeared like a somewhat complex water gun. The only indication it wasn't was the glowing blue liquid in the tank, and the various wires hooked along the back. Smiling to herself, Miu knew she needed to do one last test.

She'd convinced her teachers and the headmaster to let her out of class to work on this special invention, though she hadn't exactly told them what it was. She was sure they wouldn't have been so keen to let her work on it instead of her studies if they knew.

But it didn't matter now. Nothing did. All she could think about was the fact that she had succeeded. Or at least, she was about to find out if she did.

Pointing the gun at a mannequin she had set up in her room, she fired the gun. A beam of white light shot from the gun and touched the mannequin. Instantly, the clothes it had been wearing were seemingly sucked off its body, ripping in the process, and flew around the beam towards Miu. She let go of the trigger, and the clothes fell to the floor in front of her.

At first, Miu just stared at the clothes. Then, she began to giggle. Louder and louder, until she was cackling at the ceiling.

It was time.

Without a second thought of what the consequences of her actions would be, she burst open her door and began to run down the hall, still cackling. Classes were still in, but she didn't care. She ran as fast as she could to the first classroom she could find, and thrust open the door. Without looking, she pointed the gun and fired.

The clothes shot towards her as someone screamed, and Miu looked to see a busty girl, now sitting naked in her seat save for a pin of a spaceship in her hair. Miu only got to glance a bit at a mole on the girl's chest before she was covering up, her face red as she screamed. The clothes dropped to the floor.

"Wh-What the hell?!" the teacher cried and took a step towards Miu. Miu aimed and fired once more, and the orange-haired teacher was stripped as well. Her assets bounced as her clothes were ripped off, and she stood in shock for several moments before she screeched and leapt behind the desk, glaring dagger at Miu.

"Are you my god-sent angel?" a short boy asked, drooling onto his seat as he stared at Miu. Miu only smiled and pointed the gun at him, rendering him nude as well. Even as his surprisingly-sized dick swung down, he didn't look perturbed in the slightest. "You may be~" he said softly.

Then Miu began to fire the gun almost indiscriminately. She had to admit she aimed for the girls more often than the boys, but after some time, nearly every student in that room was naked and shouting. Miu also even saw another short kid with a harsh glare in his eyes pull out a knife that he looked ready to throw. As he stood to do so, the white-haired girl with fiery eyes sitting nearby went wide-eyed at his cock.

Miu ducked out before he could throw it, and she was still laughing as she ran down the hall. Her heart raced with adrenaline and excitement. It was working! Her underwear-removing tech had been successfully upgraded to a nudifier gun! It was the best day of her life!

She blasted into the gym, where two classes were having PE. Miu smiled as she spotted a few targets, and while some students turned to her, once they saw the gun and then saw her pointing it, they began to jump up.

Miu fired the gun at Himiko and Kokichi, their clothes ripping from their body easily and leaving their small bodies on full display. Himiko shrieked while Tenko, who was watching nearby, nearly passed out from the blood that suddenly erupted from her nose. Kokichi just looked amused. He pointedly stared at Himiko, and the girl became even more flushed as she saw the boy's dick enlarge and stiffen.

Miu then pointed the gun at a boy with an ahoge, wearing a jacket in PE for some reason, and a cute girl who looked very alarmed. Miu fired at them both and left them both naked.

The girl turned out to be a boy as his small, adorable dick appeared. Strangely, he covered both his chest and his dick as he dropped to the floor, and the other boy gasped as he covered himself up as well. A girl with lavender hair nearby suddenly appeared very interested in what was going on, though that fascination vanished when she too was shot with the gun.

Miu once again blasted almost everyone in the room before running off again, hearing shouts and screams and squeals in her wake that made her smile widen further.

She shot down the halls, passing classroom after classroom and rendering almost everyone in each one completely nude. Cameras flashed and screams filled the entire building as she ran to the reserve course building.

There, she saw a blonde girl who looked shocked when Miu burst in, so she was shot first. She screamed, mostly in fury, and tried to chase Miu, only to get tripped on the way and land sprawled on the ground with her bare ass in the air, a sight many in the room enjoyed. Miu continued shooting person after person as the fluid inside the gun was slowly depleted.

Once she was done, she moved on to another class, then another, and then finally rushed back to the main building. She could still hear people complaining and whining as she booked it back to her room. Her lungs hurt from the physical activity, but pure joy was pushing her.

When she was finally back in her room, she threw the gun on the bed and laughed a big, single, hearty laugh.

"I AM A FUCKING GENIUS!" she screamed as she walked over and sat down. She glanced at the gun and was so caught up in mentally congratulating herself for such an incredible feat that she didn't notice how the liquid was swirling. She picked up the gun. "You are my absolute pride and joy, and I think we'll do great things together." She nuzzled the gun.

And then it exploded.

Miu wasn't hurt, but there was a whoosh of air as she felt her clothes get ripped from her own body, and the room became a whirlwind of air and light for a moment before the broken gun dropped on the floor. Miu shoved her hair out of her face and looked down to find herself completely nude, her clothes nowhere in sight. But she wasn't bothered.

"Looks like I'll need more modifications," she said to herself. She figured she'd probably used it too much too fast. She'd have to work on it.

Then there was a knock on the door. "Miss Iruma, please open the door." Miu immediately recognized the headmaster's voice, and she shot to her feet, her breasts bobbing.

"A-Ah! One second!" she cried as she ran to her dresser.

"No, now, Miss Iruma," he commanded as she opened the drawer, and went pale. All of her clothes were gone, not just the ones she'd been wearing!

"N-Now's not a good time…" she said as she racked her brain, unable to think due to panic.

"Sorry, but I'm afraid I'm coming in," he said as the doorknob turned.

"N-No! WAIT!" she cried, and her arms thrust over herself as the door opened. It wasn't until that moment that she realized she could've grabbed her blanket. Jin stepped into the room and froze upon seeing her. His eyes scanned her up and down, but not in a lewd way. He frowned.

"Hm…actually, this is rather fitting, isn't it?"

"P-PLEASE LEAVE!" Miu shrieked. As many times as she'd had fantasies of being seen naked, she hadn't wanted to actually experience it.

"No. You take time out of classes to work on an invention, and it's not something beneficial, but rather a gun that removes clothing?!" he cried.

"I-It might have a practical use-"

"Not one to be tested on other students!" He sighed. "As such, your punishment for both wasted time and using students as test subjects and making a mess of a day is your current attire will be your school uniform for the next week."

"WHAT?!" Miu shrieked, stepping forward, her breasts swaying in her arm. "B-But that's-!"

"Enough, Miss Iruma. If you are seen during school hours wearing any clothing at all, you will be expelled, is that understood?" he asked. She thought about speaking back, but even just looking at his glare, not at her body, surprisingly, but at her eyes directly, made her shrivel.

"Y-Y-Yes, sir…" she said quietly. He huffed and turned, leaving her door open as he stalked away. She fell onto her butt and sighed, sitting in silence for a while as she stared at the broken pieces of the gun.

Then, she said it.

"Oh well, it was worth it."
