Reijiro Enokizu operates as a private investigator under the Rose Cross Detective Agency, distinguished by his unorthodox methods and eccentric demeanor. With blonde hair and delicate features likened to a European porcelain doll, his youthful appearance contrasts his thirty-something age. Specializing in cases blurring the supernatural and criminal, he navigates investigations through psychic intuition rather than conventional procedures.

A World War II veteran, Enokizu saw limited frontline action compared to peers, leaving his military past ambiguously defined. He shares a lifelong bond with childhood friends Akihiko Chuzenji, an occultist onmyōji, and Shutaro Kiba, a pragmatic police detective, frequently uniting their expertise to unravel complex cases tied to macabre dismemberment crimes. These investigations expose cult activities, clandestine hospital experiments, and confrontations with adversaries such as manipulative novelist Shunkō Kubo and charismatic cult leader Hyōei Terada.

Later incarnations, including his role in *The Mononoke Lecture Logs of Chuzenji-sensei*, portray him as an enigmatic presence sporting an eyepatch, delving into spectral consultations and investigating schoolyard legends. Here, he mentors student ghost-hunter Kanna Kusakabe, bridging generational divides in occult inquiries.

Enokizu balances deadpan humor with practical investigative work—interviewing witnesses, tapping into underground networks—while his personal history stays shrouded beyond fragmented glimpses of wartime service and professional ties. His actions remain consistently guided by flashes of clairvoyant insight, steadfast alliances, and a calmly relentless pursuit of truth.
