Ten years ago, a girl died at Aoba Academy and no one was punished for it.
The school called it an accident. The police looked the other way. The people responsible went on with their lives — untouched, untroubled, unbothered by what they had done. Hatsune Kuzuru was buried, and the truth was buried with her.
Then she shows up.
The new transfer student. No one knows where she came from or why she chose this school. She's beautiful in a way that makes people uneasy — too still, too watchful, too calm for someone her age. She doesn't smile. She doesn't small-talk. She just watches, and waits, and seems to already know things she shouldn't.
Her name is Tamaki Kurose. And she didn't come here to study.
