Karasuno girl's volleyball team disbanded the first day of summer during Yui's second year. It was hot and all Yui could focus on was the sweat dripping down her face, rolling off her chin, and onto the floor. She didn't worry about how gross she felt or how the girl's gym still didn't have an AC. She'd complained about it to the Dean multiple times and his reply had always been the same : Why would we spend money on a useless team?

If Yui had been more venom instead of soft lilac, she would have spat back, a useless team is the reflection of a useless school, but she knew better. Her words would have been a result of the anger and sadness that was swirling in her. The girl's team at Karasuno were a laughing stock. No amount of practice could bring the spark that used to drive the girl's team. The spark that used to make them love volleyball.

The gym was hot. A window was opened to let air in, but the way the weather was looking a cool breeze wouldn't be coming in anytime soon. Yui was practicing serves like she usually did. She wanted their to be an impact. She wanted people to see her serves and be in awe. She wanted them to see the ball as a bullet, dancing through the air, past the wall, and nail the floor with a boom. She wanted-

"Michimiya-san?" Yui was brought from her thoughts, the ball slipping from her fingertips and landing on the floor. In the moment, Yui couldn't think about the blistering heat and how her skin felt like it was melting into nothingness. The girls volleyball team looked intimidating to her, standing together, standing against her. Now if they'd stand like that on the court, towering like Giants, an unbreakable wall-

"Yeah?" She wiped the sweat from her forehead, ran her fingers through her hair and only found more sweat. "What's up?"

"We're quitting." One of the twins spoke up, nibbling on her bottom lip. She looked everywhere but at Yui, not wanting to look at their captain in the eyes. "Volleyball just isn't fun anymore."

If Yui had been a different person she would have said something, but the heat made things tiring and summer was all about change and moving on. She was scared. but she didn't say anything as she watched the team walk away.

The volleyball team was restarted the last day of summer. The heat was still there, blistering and choking like fingers around her neck and squeezing until there was no air and it was suffocating.

The heat was beginning to numb Yui. It felt like nothing to her. She felt like nothing.

She spent all summer working on her serves and spikes, but it was pointless. There wasn't a team to even play this could promote the club, but who would want to join? She tarnished the girl's reputation and made them into a laughing stock. Even her old team saw no point in such a useless team and its useless captain.

Flightless crows? What a joke.

The door gym swung up, curious eyes peering around the almost empty gym. Yui glanced over, eyeing the newcomers with a curious look of her own.

"Um hello?" The first thing Yui noticed about the girl was her speech. She had an accent, a way she spoke that wasn't completely Japanese.

The next thing was the group of girls behind her. They were immersed in their own conversations, giggling quietly. They seemed so bright, like sun rays extending onto the earth and warming everything they touched.

"My name is Choi Soojin. My friends and I wanted to join the volleyball team."

Suddenly, the room was bright and blinding. The heat came in full force and Yui felt sweat dripping down her cheeks and-no, she was crying. Why was she crying?
