Jack Frost (잭 프로스트) is an ongoing manhwa series by Jinho Go (고진호). Jack Frost follows the story of Noh-A Joo, the new student at Amityville High School. Things start off rather poorly for Noh-A as she quickly comes to realize that the school is not as it appears. Caught in an interschool war between vampires, monsters, and other creatures, she must quickly learn what her new role is as the "mirror image," and how to handle the weird nurse Jin, the mysterious Jack Frost and his boss, Helmina. Not to be confused with the Jack Frost films (any of them) or the demon that goes hee-ho!.
