Фламберж

The Gin Yomihime (銀読姫, literally "silver reading princess") or Silver Biblioprincess, otherwise known as the custodian of the Long-Lost Library. She is often called just "Flam" for short. She appears to be a girl in her teenage years, with long silver hair and sharp magenta eyes. She wears a white straitjacket with nine padlocks, although she says that she chose to wear it herself because she thought it "matches Hal's tastes". In comparison to Huey's technique of retrieving Phantom Books from Dalian, the method used by Hal to retrieve books from Flam is shown to be very raw, painful and less dignified.

She is often seen as a very arrogant and unpleasantly blunt character, and enjoys harassing Hal by accusing him of having perverted tendencies or a dirty mind. (Taken from Wikipedia)
