Ketsu, a famous astrologer and sorceress, has a wise and calm character. Her essence is permeated with phlegm, which allows her to remain constant even in the most difficult situations. However, sometimes she is capable of insouciance, because Ketsu knows how to create a balance between seriousness and relaxation. Ketsu's main passion is the stars. She feels the power and magic of their healing rays, and therefore constantly studies their movement and meaning.
