リアン・ルーチェ・ディメルモール

Jun's fiance chosen for him by his grandfather. She is a member of the Dimermore, one of the cadet branches of the Brandole family. She is very much the naive, pampered aristocrat with all of the inherent arrogance you would expect of someone born to such a family. That said, she has an immense capacity for love and a tendency toward emotional dependence to those few who manage to get inside her guard. Her Moon Ties ability, Brain Tyrant, allows her to read and alter the memories of others, as well as control their minds. She has very little hesitation about using it, which is one of the points she clashes with Jun on early on.
She was originally engaged to Id before his attempt to elope with Yukari, Jun's mother. This engagement was immensely pleasing to her, and, similar to Belche, she carries a sense of abandonment about the incident, though not to the extent she does.
