Rank 6.
Owner and pastry chef of the pastry shop 'Maison Sucré'.
Belongs to the High School Division. Her confectionery skills are top-notch, and her shop consistently ranks high in the sweets category voting. She is immensely popular, especially among female students.
While she handles all types of Western sweets flawlessly, she constructs everything in her head and never creates recipes or notes. Consequently, she has the troublesome trait of being the only one who can recreate her work. Furthermore, while she is perfect at making things herself, she is so intuition-based that she is extremely poor at teaching others.
On the other hand, she is a combat-oriented student counted among Rank 6, the absolute elite of the academy, and she is active in rank matches.
Her innate ability is 'Confectionery Workshop'.
Creates weapons and tools from sweets and sugar. Although they are always themed after candy or sweets, their quality is comparable to that of a master craftsman. The mana consumption is low, but in exchange, it consumes a massive amount of her own calories, so it cannot be overused. Incidentally, everything created with this ability is edible and has no expiration date. Retria never uses this ability to make the sweets she sells in the shop.
