Mistrune, nicknamed Mist for short, is one of Lotte and Asuha's friends. She is the daughter of a viscount. She is very notable for having the biggest bust among Lotte's group of friends, including Elika and Ingrid but excluding the staff in Lotte's manor. Mistrune is also the most perverted one among the girls, although she keeps this side of hers usually hidden. She has once held a crush on Naoya when he entered the girls' school. Initially, Mistrune has confessed to Asuha that she and the two girls have once tried to befriend Lotte before Asuha came, only to remember that Lotte cannot be approached easily due to her royal status. Thanks to Asuha's meddling, the three girls become friends with Lotte at last. Mist has admitted that she is fourteen years old but still earns the fiery jealousy of the girls due to her chest. Mist has stated that her wet nurse is Edda, Effie's older sister who held the biggest bust in their family in terms of proportion. Mist has said that she drank directly from Edda during her childhood, leading the other girls to often misunderstand this as the reason for Mistrune's large chest.  (Source: Wikipedia)
