Quarter Queen

Quarter Queen (クオーター・クイーン, Kuōtā kuīn) is a thirteen-year-old girl who is the second victim of the Los Angeles BB murders.

Appearance
Quarter Queen is is a young girl with blonde hair.

Plot
Quarter Queen lives in a small apartment with her single mother. The apartment is actually a single bedroom apartment meant for college students, but the family is very poor.

While her mother is out of town, Quarter Queen is murdered, four days after the murder of Believe Bridesmaid. She is drugged, but the ultimate cause of death is blunt force trauma to the skull. Her eyes are crushed post-mortem. As with all of the other murders, Wara Ningyo (three, in this case) are left at the scene of the crime.

While at Believe Bridesmaid's house, Naomi Misora and Rue Ryuzaki decipher a code left behind by the killer. Two volumes of Akazukin Chacha are replaced with the book Insufficient Relaxation, by Permit Winter. Using the Roman Numerals that were carved into Bridesmaid's back, they discover that the first letter of the first word on every page that coincides with the Roman Numerals, and the fourth letter of the first words on pages that were "wrapped around" to fit the Roman Numerals, it is discovered that a message was left spelling out Quarter Queen's name.

When observing the crime scene, Misora and Ryuzaki realize that the glasses the victim was found wearing did not actually belong to her, and that her contact lenses had been removed. The glasses are another message left behind to represent the detectives' blind spot.

Naomi finds the death of Quarter Queen to be particular tragic. This is due in part because she was so young, but also because her age is the same as the teenage criminal who Naomi had been unable to will herself to shot when she was on a drug heist with some other FBI agents.

Even if Quarter Queen had not been murdered, she would have died on August 4, as the first three victims of the Los Angeles B.B. Murder Case are all killed on the day their lifespan was supposed to come to an end anyway. However, it is also possible that her life was originally supposed to end because she was murdered by Beyond Birthday.

Trivia

 * She had a prescription for glasses but almost always wore contact lenses.
