Isabelle Norton

A first-year student in the high school division at Serendia Academy, she is the daughter of Count Kerbeck. She is one of the few people who knows Monica's true identity, the Silent Witch, and is indebted to her for helping her exterminate the pterodragons that were causing a dragon plague in the lands of Count Kerbeck. She helps Monica out behind the scenes at Serendia Academy, and sometimes even plays the role of a villainess, pretending to bully Monica, who is set up to be Isabelle's caretaker.
