Trickster: Makoto Noro & Nao Nakamura

A member of the Boy Detectives Club and the sole female of the group. She's a thorough shut-in girl who never leaves her department, and only checks events outside through her owl, with her speciality being communications and hacking. She claims to be the "most healthy" member of the group as she's constantly seen exercising with machines in her room while doing Detective Work. She checks on and remains friendly with Hanasaki despite Inoue's stance after Hanasaki's kidnapping.

She is revealed to be a college graduate successfully skipping several grades, and that she is a shut-in only because she finds comfort in home as she has no "dark history" as she puts it, and that she pays her taxes accordingly so she sees no problem in her current life-style (both her shut-in life and her Detective work) and merely likes it that way.

A police officer, and an acquaintance of Akechi. She has a business relationship with Akechi, allowing him free action in exchange of giving the police any credit for whatever case he solves. It is revealed that she is Kaijin Nijuu Mensou's girlfriend and has been brainwashed by him.
