Sero's sister

Chapter 5: Sparks Between Us

The next few days passed in a blur for Y/N. Her mind kept replaying the battle exercise over and over again—the moment she let go, the raw force of her quirk, and the way Bakugou had looked at her afterward.

It felt like something had shifted. Not just in the way she fought, but in the way she felt about him. Bakugou wasn't just some arrogant jerk anymore. He was still cocky, sure, but he wasn't the one trying to tear her down like Kaito had. If anything, he seemed to want her to break free from whatever chains were holding her back.

That thought both scared and intrigued her.

Now, as she walked toward the training grounds for another round of combat practice, she couldn't shake the uneasy feeling growing in her chest. Today would be different—she could feel it. Ever since that moment when she stopped holding back, it was like the tension between her and Bakugou had been ratcheted up several notches.

She wasn't sure if that was a good thing or a bad thing.

Y/N arrived at the training field to see students already paired off. Bakugou was on the other side, working through some warm-up moves with his usual intensity. She kept her distance, grateful that today's matchups wouldn't pair them together again.

"Y/N!" Mina called out, waving her over. "You're with me today!"

Y/N smiled, relieved to be working with someone who wasn't going to push her buttons the way Bakugou did. Mina was one of the few people who made her feel at ease, someone who didn't pry into her past or push her into uncomfortable places.

"Ready to kick some ass?" Mina asked with her usual bubbly energy.

"Always," Y/N said with a grin, pulling on her gloves and readying herself for the match.

The exercise started, and for the first time in days, Y/N felt herself relax into the rhythm of combat. Mina was an agile partner, and the two of them flowed through the match with ease, working in sync to take down their opponents. It felt good—like Y/N was finally in control again.

But just as she began to feel comfortable, a familiar, fiery presence caught her attention from across the field.

Bakugou.

He wasn't even looking at her, but Y/N could feel the weight of his presence, like the gravity in the air had shifted the moment he stepped into the ring. He was sparring against Kirishima this time, the clash of their quirks lighting up the battlefield. Kirishima's hardening quirk clashed against Bakugou's explosions, both of them grinning like they lived for the fight.

Y/N tried to focus on her own match, but her eyes kept drifting back to Bakugou. His movements were sharp, precise, and full of energy. Every explosion was calculated, his power controlled in a way that made it clear he had long ago mastered the thing she was still struggling with: control.

For a brief moment, their eyes met. Y/N's breath caught in her throat as Bakugou's intense gaze held hers for just a second too long. It wasn't the usual look he gave—like he was sizing her up or challenging her. This time, it felt... different. Almost like he was reading something deeper inside her, something she wasn't ready to admit.

But then the moment passed, and Bakugou turned back to his match with Kirishima, leaving Y/N standing frozen in place.

"Y/N, heads up!"

Mina's voice snapped her back to reality just in time to dodge an incoming attack. Y/N barely managed to redirect the blow, her heart still racing. Mina gave her a confused look, but Y/N forced herself to focus, shaking off the distraction. She couldn't let him get to her, not here. Not like this.
