Miu iruma(genderbent)

The Hope's Peak science lab was a total disaster area, and honestly, you shouldn't have expected anything less when you agreed to hang out with Misa—uh, Miu. For the past two hours, you had been sitting on a lab stool, watching her do the absolute most reckless stuff imaginable—mixing volatile chemicals without measuring them, ignoring safety warnings, and loudly bragging about her "golden-ratio genius" brain.

"Bwahaha! Just watch! This enhancement serum is gonna change everything!" Miu cackled, throwing her head back as she aggressively shook a beaker filled with a glowing, bubbling pink liquid. "Those stuck-up professors don't know crap! A real genius doesn't need formulas, she just needs raw talent!"

Before you could even tell her to step away from the burner, the solution turned a violent, angry neon green. POP!

The beaker exploded in a thick cloud of sparkling, sweet-smelling smoke. Miu coughed, dropping to her knees as the smoke completely engulfed her. You scrambled off your stool, waving the air clear, ready to chew her out for almost blowing the room up—but as the mist cleared, the words died in your throat.

Sitting on the tile floor was a tall, lean, and distinctly masculine figure. Her school uniform was straining at the seams, and her long blonde hair was a mess. Her goggles hung lopsidedly on a sharp, boyish jawline, and when he finally looked up at you, his pink eyes were wide with shock.

Miu blinked, looking down at his large, grease-stained hands. His face instantly flushed a violent crimson as he scrambled to his feet, finding himself suddenly much taller than you.

"H-Haah?!" Miu's voice cracked spectacularly before settling into a deep, raspy, and incredibly cocky male baritone. He gripped your shoulders, his eyes wide with a mix of terror and excitement. "Oh my god... it actually worked! Look at this! I’m a total stud! My genius brain just created the ultimate biological breakthrough!"

Before you could say anything, Miu yanked open the waistband of his pants, peeking down into his trousers to check the results of the transformation. His jaw dropped, his face turning an even brighter shade of red as he stared at the brand-new, fully functional male genitalia he had just grown.

"Holy crap... it's huge!" Miu barked out a wild, highly suggestive laugh, his voice vibrating with newfound, dirty confidence as he snapped his waistband shut and smirked down at you. "A real, working cock! My genius just created the ultimate biological masterpiece! Hey... you're a girl, right? Don't just sit there drooling! You're gonna help me test out how this bad boy works, or are you too chicken?!"

He stepped right into your personal space, his chest heaving. But despite the crude bravado and the aggressive horniness, his hands were trembling slightly—his classic insecurity proving that even with his brand-new male package, he was still the same easily flustered Miu underneath.
