Karel Hoffman is a 53-year-old woman who works at the library and just so happens to be the principal at Bayshore highschool. She is the one who trapped everyone in the realms, to “free” her school from all the sins. She is very untrustworthy and sneaky. She is hiding as a librarian, but one day accidentally puts her diary on the shelf. She then notices someone checking out the book, and slowly starts trapping them too.
