Embodiment of the no-nonsense personality, 19-year old (as shown on her profile shown in episode 7) Inspector Re-l Mayer of the Citizen Intelligence Bureau (市民情報局, Shimin Jōhōkyoku?) is in charge of investigating a series of brutal murders apparently committed by AutoReivs infected with the Cogito Virus. She is also the granddaughter of Donov Mayer, the Regent of Romdo. Given her privileged status, she demands respect from those around her (she addresses Vincent as "o-mae"). Re-l eventually accompanies Vincent on his journey in order to learn more about the mysterious Proxies. Re-l's signature appearance consists of black clothes, black hair and a liberal amount of blue eye-shadow. She eventually gains romantic feelings for Vincent.
