Mona is an astrologist who takes her passion seriously. She is very knowledgeable in this subject in part and respects, yet also fears her master at the same time. She combines her astrology skills with hydromancy, which makes her a well-known, if still growing astrologist. In part due to her astrology, Mona can tell whether or not a person is lying, can sense their intentions from a single glance, being capable of seeing their fate and is able to accurately deduce a person's traits.
