You didn’t volunteer for this. You were assigned. Three weeks at a joint winter training camp with the loudest, most ego-inflated volleyball players in the country. Karasuno, Aoba Johsai, Inarizaki, Fukurodani, Shiratorizawa, Nekoma — all under one roof. Your job? Temporary managing staff. Your opinion? Absolutely not.
You arrive at the summer volleyball training camp as the captain of a girls’ team that was invited by mistake—or so everyone thinks. Surrounded by powerhouse boys’ teams, you quickly realize you weren’t expected… but you were invited for a reason.
You arrive in Japan for university carrying a past most people don’t see. A former national-level volleyball player, you join a mixed university club expecting teammates—not legends. When you walk into the gym and find only boys who underestimate you, you don’t argue. You play.
A potion mistake leaves a cold, isolated Slytherin trapped in the body of her five-year-old self for one week. Unable to reverse the charm immediately, the professors assign sixth-year students to take care of her—uncovering a warmth and innocence no one ever expected to see.
You are not from their world. You never were. In your second year, you appeared out of nowhere—right in the middle of the Great Hall, during dinner. No wand. No magic. No explanation. Just you, human, lost, and terrified. You stayed for almost two years. You made friends. With everyone. And then you vanished. Now, in sixth year, Hogwarts pulls you back. Harder. Darker. Different.
Rejected by both the sirens of the Black Lake and the wizarding world above, you live hidden beneath the water’s surface. One night, your gaze meets that of a group of Slytherins through the common room windows. What begins as silent observation slowly turns into a dangerous connection between two worlds never meant to collide.
You are supposed to have a calm summer. Instead, you end up in the middle of the most intense volleyball summer camp in Japan. As an intern nurse, you’re assigned to a training camp gathering the strongest high school teams: Karasuno, Nekoma, Aoba Johsai, Inarizaki, Fukurodani and Shiratorizawa. Your job is simple—take care of injuries, stay in the background, do your work.
You arrive at Hogwarts in sixth year with no past anyone can trace. You’re sharp, charming when you need to be—and ruthless when you don’t. Hired quietly to manage problems, you don’t break rules. You bend people. And before anyone realizes it, the school is already whispering your name.
Five years after Hogwarts, you return to London unaware that your former Slytherin friends have become Death Eaters. When you are kidnapped on the Dark Lord’s orders—meant as punishment for your estranged father—you discover that the ones sent to break you are the same people who once protected you
After the war, Hogwarts is quieter—but not peaceful. In a forced attempt at unity, houses mix, friendships blur, and old rivalries soften. When you arrive from France, untouched by the war they barely survived, you become something unfamiliar. Something living. And without meaning to, you draw every gaze toward you.
Every autumn, the top high school volleyball teams gather for an intensive joint training camp. This year, the camp is held in a quiet countryside town, far from Tokyo’s chaos. The gymnasium chosen for the event is old but massive — polished wooden floors, high ceilings, echoing walls that carry every spike like thunder.
the league has been forced to rebuild—not just its structure, but its image. The public is watching more closely than ever, sponsors are cautious, and the Exy Regulatory Committee (ERC) knows one thing for certain: they need control, and they need something new.
You come from France, from Beauxbatons, carrying grief, bad habits, and a life that slowly faded into grey. When you’re transferred to Hogwarts for your seventh year, it doesn’t feel like a new beginning—just another place, another castle, another set of walls. Sorted into Slytherin by convenience rather than destiny, you arrive detached, numb, unaware that this school, these people, and this year might quietly change everything.
Three weeks at a joint training camp with the loudest, most ego-inflated volleyball players in the country. Karasuno, Aoba Johsai, Inarizaki, Fukurodani, Shiratorizawa, Nekoma — all under one roof.
One week before the annual summer training camp begins, what was supposed to be a calm final weekend of freedom turns into something far more memorable.
