Noha-A Joo is a new student at Amityville High School. She is known as a "mirror-image"; a person who has died but becomes immortal. Her blood has the ability to heal wounds.

Noh-A is excited to learn that she is a mirror image, and does not show any signs of unhappiness at her new role in Amityville. She is quite naive and manages, somehow, to get her head cut off several times, usually by Jack.
