Taniyama, Mai

谷山麻衣

Mai is a first-year high school student who temporarily works as an assistant for SPR to repay a debt. This arrangement begins after she accidentally injures Naru's regular assistant, Lin, and breaks a camera used during an investigation of an old building at Mai's school (it is later revealed that the camera was covered by insurance, and the reason for her employment remains unknown). Following the conclusion of the first case, she is offered a regular part-time position with SPR and serves as both an office and on-case assistant. She refers to Shibuya as Naru because of his narcissistic nature.
