Clarissa Mayer

Clarissa serves as Arnold's family doctor and as his private tutor. She is an intelligent and caring woman with a doting older sister temperament. She can speak three languages - German, English and Japanese.
Clarissa is Vincent's niece, which makes her somewhat familiar with the occult, but she isn't a believer in it. She teaches Arnold to play the piano. She suffers from lightheadedness in the morning due to her low blood pressure.
