Yuuki, Reiko

結城澪呼

Reiko is a member of the Occult Research Club and is well-versed in spiritual and dubious topics, such as curses and fortune-telling. She is Switch's sworn rival, and the two have engaged in several disputes regarding the existence of ghosts. Despite their inherent rivalry and mutual animosity, Yuuki actually gets along quite well with Switch (and vice versa).
Reiko possesses a creepy personality and unnerving mannerisms, yet she does seem to care for her friends. Her appearance resembles that of Sadako from the movie adaptation of "Ring".
