The only normal human being in the office that assists Asagi in any paranormal case. He is often depicted as a character who is easily pushed around without compensation. Furthermore, he tends to be gullible towards disguises and tends to become uneasy with any homosexual concepts that come his way. Naoki was first acquainted with Asagi in his days of being an adolescent school student. Together they successfully solved the mystery of the ghost of a suicidal female student who haunted the halls of the school. Were Naoki to not be involved with solving the mystery with a disguised Asagi at the time, he would've lived a normal human life ever since.
