Sero's sister

Chapter 1: Sparks Fly

Y/N Sero had grown accustomed to being known as Hanta's little sister. At U.A., it was hard to escape the shadow of your sibling, especially when they were in the same school, part of the same friend group, and living the hero life with you. She didn't mind it most of the time. Hanta was chill, easy-going, and generally had her back.

But as she looked around Class 1-A's common room, the energy was anything but chill. It was chaotic. It usually was, with Kaminari sparking harmlessly from an overuse of his quirk, Mina egging him on, and Midoriya pacing while muttering to himself. Even Todoroki seemed more animated than usual, though his version of animated was a mere raise of an eyebrow.

And then there was him.

Katsuki Bakugou stood by the window, arms crossed, glaring out at nothing in particular. His explosive personality radiated off him in waves, and Y/N could sense it from across the room. That same intensity that had drawn her attention the moment she joined 1-B. It wasn't like she wanted to notice him, but it was hard not to. Everything about him screamed danger, from the smoldering glances to the unpredictable temper.

She hated it. Or at least, she told herself she hated it. But there was something about that fire he carried—something wild and passionate—that made her heart race every time they crossed paths.

"Hey, Y/N, you coming to practice tomorrow?" her brother's voice snapped her out of her thoughts.

"Huh? Oh, yeah, totally," she answered, blinking as she turned to face Hanta, who was lazily stretched out on the couch.

"You good? You looked a little out of it," he teased, nudging her foot with his own.

"Yeah, yeah, just thinking," Y/N shrugged, not willing to admit she'd been staring at a certain explosive blond for the past few minutes.

"Hmmm... thinking about anyone specific?" Hanta raised an eyebrow, a knowing smirk on his face.

Her cheeks flushed slightly. "Shut up, Hanta."

He laughed, clearly enjoying her discomfort. "Alright, alright. Just don't space out when we're sparring tomorrow, okay? I don't want to have to explain to Mom that you got blown up 'cause you were distracted."

"I won't!" Y/N shot back, standing up to stretch. "I'll be fine."

As she gathered her things to head to her room, she felt a prickle of awareness. Glancing over her shoulder, her gaze collided with Bakugou's. His crimson eyes were intense, almost like he could see straight through her. Her breath caught in her throat for a second, but she forced herself to look away, quickly making her escape up the stairs.
