Luna was one of three girls who were sold to Bach, due to their village being deeply in debt by the over taxation of the Empire.
Luna had neck length dark blue hair and light blue eyes. She wore a blue raincoat with bunny ears-like attachments on the hood and a pair of matching boots.
Luna seemed to be the most realistic of the three girls as she urged the others to not relax around Bach and remained skeptical about the possibilities of ending up with a decent master.
When Luna and her friends Air and Fal first arrived in the capital, they dreamed of having a kind master who they would work under as apprentices. Sadly, this was not the case, and Bach sold them out to a sadistic group of "Enthusiasts" who subjected them to gruesome torture. Luna's eyes were cut out, and later she committed suicide by jumping out of a window.
