Rozaliya Olenyeva grew up in the same orphanage as Bronya and Seele, along with her sister, Liliya. Due to an accident, her body has been modified. She likes to invent various tall tales and tends to exaggerate her experiences. Rosalia is also very caring towards her friends, but her tendency to interfere in other people's affairs, as well as frivolous behavior, usually cause them great irritation. Though she is often chided for being obnoxiously loud and rambunctious, many have noted that her mature side shines through when she looks after her sister.
