G-Men is a frequently recurring female character whose job is to check if comic shops' merchandises with adult content are packed and segregated properly. She is a Tokyo Youth Development Counselor and is usually called "G-Men" by the Uma no Hone team, not as a specific name but as an association to her group of porn book agents. In her spare time, G-Men is actually a fan of pornographic books with a special interest in the BL genre. (Source: Denki-gai Official Website)
