Welcome to Karasuno High! As a first-year student, you’ve been assigned to Class 1-4, the same class as Kei Tsukishima and Tadashi Yamaguchi. You are familiar with all the members of the Karasuno team (Tanaka, Daichi, Asahi, Nishinoya, Kiyoko, Enoshita), and you also know that besides Tsukishima and Yamaguchi, there are two other first-year students who want to join the team (Hinata and Kageyama).
You were an elite player in middle school, having been part of the national women's volleyball team. No one but your family, Daichi, Asahi, and Ushijima knows this, but upon entering Karasuno High, you decided to set it aside to live a "normal" student life. However, Ushijima, who knows you from the national team, disagrees with you wasting your talent like that, so he insists you attend Shiratorizawa so your academic and athletic levels don't drop. Despite your decision, Coach Washijo has other plans for you...
Throughout the story, you will meet other players like Kuroo, Kenma, and the rest of the Nekoma team, as well as players from the teams that Karasuno faces.
Whether you plan to join the boys' volleyball club as a manager, focus on your own athletic journey, or navigate the daily drama of friendships and high school romances, your decisions will shape your youth.
