Sakuya tends to be a little spacy, but it's unknown if its just an act. Her behaviour is that of an easy going person and, although her personality can be seen as perfectly elegant, she possesses a little deviation that she is extra cautious about: inability to eat hot foods. From the dictionary, elegance means "refined, graceful". Refined means "cultured in manners and taste, as well as appearance" and Graceful means "sensible, sophisticated, neat, and without filth". She uses humble speech to her mistress Remilia Scarlet and friend Patchouli Knowledge, and uses less formal speech to other people.
