Haikyuuasylum Stories

Yuki, a mysterious, beautiful omega with a blank record and unknown origin, arrives at Union Asylum-Academy. He has no memory of how he got there, but everyone seems to already know him-or want him. As the story unfolds, Yuki begins receiving cryptic letters written in his handwriting... letters he doesn't remember writing. Secret passages, hidden wings, and violent incidents begin to piece together a far bigger conspiracy involving staff murders, manipulated memories, and a long-forgotten experiment.
