Emma Klever is a student who attends the Regarden Magic Academy alongside Will Serfort. Following her graduation, she becomes a member of the Wind Faction.

Her personal history is marked by a deep and painful trauma involving the sacrifice of her younger brother, an event that left a lasting emotional wound. She also has a unique physical condition known as Flower Blight, which causes her skin to break out in rashes and strange sprouts to grow from her body like a curse whenever she touches certain types of flowers.

Emma has a gentle demeanor on the surface, but she carries inner pain that is not immediately apparent to others. She shares a close, childhood friendship with Julius Reinberg.

Emma's role in the story centers on her vulnerability being exploited due to her past trauma. The emotional scar from her brother’s death left her susceptible to manipulation, and she is placed under puppet magic by a user of shadow magic, effectively turning her into a controlled puppet for an entity known as Shade. Her condition becomes a key plot point when Julius observes her behaving strangely. Despite her Flower Blight, she is seen carrying a bouquet of Belladonna flowers, a type that should cause her to become ill. Julius notices the inconsistency and questions her, an act that leads to the exposure of the incident involving her manipulation. There is no information available regarding specific magical or combat abilities she may possess.
