It was a typical spring day. The air of Monday signaled the arrival of another school week, a week filled with new opportunities and challenges. The afternoon sun shone brightly, its golden rays casting a soothing glow through empty school hallways. The bell rang and soon they were filled with chattering students. It was a day like any other, but not for Yui-chan. This girl had a mission: to capture the attention of her crush, Senpai.

Yui-chan was a shy, frail, but generous soul who's always willing to help others. Utterly smitten with her Senpai, she craved his attention. But he seemingly indifferent to her existence. Maybe she was too weak? Maybe Senpai wanted a woman who is strong and athletic? Frustrated and believing that he was unhappy with her, she decided to make a drastic decision to win his heart and prove that her love was not in vain. "I know! I'll be a hero, like Senpai! A super-hero!" she thought. "...And prove how strong I've become!"

As she rehearsed in her head what she was about to show, Yui turned the corner and suddenly found herself face-to-face with her Senpai bumping into each other in the secluded hallway. Her heart skipped a beat as she looked up at him. That wasn't something she had planned! Though, she quickly regained composure.

"Oh, erm... Senpai! S-Sorry... I didn't mean to run into you so suddenly! Are you hurt? Oh, thank goodness you're okay."

With a subtle nod, Yui-chan looked around, checking if they were alone, then turned back to Senpai. Now it was her chance. Yui gathered all her courage & looked directly into his eyes. The guy seemed puzzled by her behavior. He was about to say something when the girl spoke up, interrupting him.

"S-Senpai, wait... Before we go to class, there's something I need to show you, something important."

She gulped, determination shone in her eyes.

"Just watch... please."

And with that, Yui-chan stepped back, creating some distance between them. Before Senpai could respond, she took a deep breath & closed her eyes, her fingers curled into loose fists. Suddenly, her entire body quivered; she began to grow larger & bulkier, gaining immense muscles as her skin turned green, her school uniform strained against her frame. She gritted her teeth. Her clothes stretched to their limit before finally ripping, revealing her formidable appearance. Eventually the process was complete. Yui-chan stood taller, stronger, more muscular than ever. She opened her eyes & looked at Senpai with a mix of nervousness & anticipation.

What stood before Senpai now was a towering figure of the She-Hulk, her green skin gleaming as muscles rippled under its jade surface. Her white shirt was reduced to scraps that barely covered the curves of her enhanced chest, leaving her muscular arms and torso fully on display. Her patterned magenta skirt was tight around her mighty thighs, yet still intact. Her long yellow tie managed to stay on, dangling around her neck & reaching just above the end of her six-pack. Her hair had darkened to a deep shade of green, yet still retained the short pigtails style with the yellow bands securing them in place. She stood barefoot, her feet resting against the cool tile floor as she regarded Senpai. However, despite her intimidating size & sheer power, Yui's face still held its usual sweetness, her eyes somehow stayed their familiar blue.

"W-Well, S-Senpai? W-What do you think? Am I strong enough?" Yui-chan asked and flexed both her arms shyly.
