The Witch Trial of Sixteen Magical Girls

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. "It has been determined that you are most likely [Witches] - you will pose a threat to human society." "Please continue to live here as prisoners." The daily routine that was once taken for granted collapsed.
