Re-l Mayer

Embodiment of the no-nonsense personality, Inspector Re-l Mayer of the Citizen Intelligence Bureau 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 expects respect from people around her, and speaks as such (she addresses Vincent as "o-mae").

Re-l accompanies Vincent on his journey in order to learn more about the mysterious Proxies, but having been living in comfortable conditions and being spoilt by Iggy all her life, she finds the "outdoor hiking" experience increasingly unbearable, and throws tantrums at both of them (often with comical effects). During the period that they get stranded without wind, she passes time by taking the both of them as study subjects. Her narration reveals her to be a very analytical person. Re-l is a young woman who wears black clothes, has black hair and is known for her blue eyeshadow. She eventually comes to share Vincent's feelings, but shows it subtly.
