With full expectations for her new high school life, Emma fell into sleep. But when she woke up the next day, she found herself in a dark cell. She had no clue why she was imprisoned. And this prison is located on an isolated island - Emma was in confusion. And she is not the only one who is in chaos... A talking owl announced to the 16 girls who came here.

The daily routine that was once taken for granted collapsed.
