**Chapter 3: U.A. High School**

Rin stood nervously beside Aizawa, her eyes fixed on the sprawling campus of U.A. High School. She had never seen so many people in one place before, and the air was electric with excitement and anticipation. Aizawa's hand rested on her shoulder, his eyes scanning the crowd as he led her through the gates. As they walked, Rin couldn't help but feel a sense of awe at the sheer scale of the school. There were students everywhere, all chatting and laughing with each other. Rin felt like a small fish in a big pond, and she wasn't sure if she was ready for this. Aizawa seemed to sense her unease, and he squeezed her shoulder reassuringly. "You'll be fine, Rin," he said. "Just be yourself, and you'll make plenty of friends." Rin nodded, trying to feel more confident. But as they approached the entrance to the school building, she caught sight of a boy with a messy shock of blond hair and a confident grin on his face. He was staring at her, his eyes narrowed as he took in her appearance. "Who's that?" Rin asked, her voice barely above a whisper. Aizawa followed her gaze, his eyes flicking to the boy before returning to her. "That's Katsuki Bakugou," he said. "He's a student here, and he's... quite the character." Rin's eyes were drawn back to Bakugou, who was now walking towards them with a swagger in his step. As he approached, Rin could feel his eyes on her, boring into her skin like a physical presence. "Well, well, well," Bakugou said, his voice dripping with amusement. "Look what we have here. Aizawa's new protégée, I presume?" Aizawa's eyes narrowed, his grip on Rin's shoulder tightening. "Bakugou, this is Rin," he said. "She's a new student, and she's going to be in your class." Bakugou's eyes locked onto Rin's, his gaze piercing. "I'm Katsuki Bakugou," he said, his voice low and husky. "And you are...?" Rin felt a surge of unease as she met Bakugou's gaze. There was something about him that made her feel like he could see right through her, like he knew secrets that she didn't even know herself. "I'm Rin," she said finally, her voice barely above a whisper. Bakugou's grin widened, his eyes glinting with amusement. "Well, Rin," he said. "I'm going to make sure that you have a very interesting time here at U.A. High School." As Bakugou walked away, Rin felt a shiver run down her spine. She wasn't sure what she had just gotten herself into, but she had a feeling that it was going to be a wild ride. Aizawa's eyes watched Bakugou's retreating back, his expression thoughtful. "Be careful around him, Rin," he said. "He's... complicated." Rin nodded, her eyes still fixed on Bakugou's back. She had a feeling that she was going to have to be careful around him, indeed. As they entered the school building, Rin was hit with a wave of noise and color. There were students everywhere, all chatting and laughing with each other. Rin felt like she was drowning in the chaos, but Aizawa's hand on her shoulder kept her grounded. As they made their way to the classroom, Rin couldn't help but feel a sense of excitement. She was starting a new chapter in her life, and she was ready to face whatever came her way. But as she glanced back at Bakugou, who was watching her with an intense gaze, she couldn't help but wonder what lay ahead.
