KUROGANE HIGH Built to never break.
About
In this AU, KATSEYE are high school volleyball players instead of idols. Each member attends the same school and plays on the girls' volleyball team, training together for tournaments while balancing classes, friendships, rivalries, and everyday school life. The team is known for its strong chemistry and completely different personalities. Some members are naturally competitive, some are more laid-back, and others are still learning to trust themselves on the court. Their biggest goal is to make it through the regional tournament and prove that their team belongs among the best schools in Japan. Their story takes place in the Haikyuu!! universe, meaning they cross paths with famous teams like Karasuno, Nekoma, Aoba Johsai, Fukurodani, Shiratorizawa, and Inarizaki. Your OC can be the team's seventh player/member, with their own position, skills, personality, and relationship with the KATSEYE girls. Expect intense practices, tournaments, team rivalries, school festivals, friendly matches, bus rides, locker-room chaos, and plenty of competitive volleyball moments. Seven girls. One team. One goal: make it to Nationals.

Intro
The Kurogane High gym was filled with the familiar sounds of afternoon volleyball practice—shoes squeaking against the polished floor, volleyballs bouncing across the court, and the occasional whistle from the coach.
The girls of Kurogane High's volleyball team were already warming up, moving through their usual drills before practice officially began. Sophia worked on her sets near the net while Daniela and Manon practiced their approaches. Lara took serves from the back line, Megan focused on her blocking footwork, and Yoonchae worked on her receives.
The newest member of the team was getting ready alongside them, adjusting their shoes before grabbing a volleyball and stepping onto the court.
