Description
Akihiko Chūzenji was born on the Shimokita Peninsula and raised by his grandparents near the sacred mountain Osorezan. His father worked as a Christian missionary, contrasting with a family heritage of Shinto priesthood inherited from his paternal grandfather. This dual religious background shaped his worldview, though he personally developed no faith in either system. His family consists of his wife, Chizuko Chūzenji, and a younger sister, Atsuko Chūzenji, who works as a reporter. He also cares for a cat named Zakuro.

Conscripted during World War II, he served at the secret Mimasaka Institute of Modern Medicine. There, he participated in research on memory, recognition, and consciousness, with applications in religious brainwashing. These experiences left deep psychological scars, leading him to avoid discussing his wartime past due to lingering trauma.

Professionally, he worked as a high school language teacher in postwar Tokyo (1948). There, he met student Kanna Kusakabe, and together they investigated supernatural rumors and school legends, including a library ghost curse and the "Red Paper, Blue Paper" phenomenon—one of the institution's Seven Wonders. Despite a stern demeanor and perpetually grim expression, he guided Kanna in logically resolving these cases. He later transitioned to running "Kyogokudo," a secondhand bookstore in Nakano, while concurrently managing the family-owned Musashi Seimei Shrine. This career shift facilitated his deep love for literature and encyclopedic knowledge of rare texts.

His personality is defined by skepticism, logic, and a commitment to rationality. He frequently asserts, "There is nothing mysterious in this world," dismissing supernatural explanations for empirical reasoning. Though outwardly pessimistic and sarcastic, he demonstrates care for others by selectively concealing painful truths to prevent further harm. He avoids violence and adheres strictly to legal boundaries, emphasizing respect for all individuals. His hobbies include collecting written materials and enjoying Japanese dry sweets, though he abstains from alcohol.

Chūzenji's primary ability involves resolving mysteries through deductive reasoning and exhaustive research, often drawing from his vast repository of book knowledge. His "exorcisms" deconstruct rumors or fears using tailored language—scientific, religious, or cultural—to help individuals overcome psychological distress. Examples include demystifying a vanishing student incident linked to the "Red Paper, Blue Paper" legend and investigating a spectral soldier carrying a cursed casket, revealing mundane explanations behind both. He occasionally adopts disguises, such as impersonating low-level criminals or priests, to gather information but refuses to employ manipulation for malicious purposes.

He maintains long-standing friendships with Soichiro Enokizu and Tatsumi Sekiguchi, dating back to their high school years. He frequently collaborates with Soichiro's brother, Reijiro Enokizu—a mysterious eyepatch-wearing figure—on cases, including a jazz-bar-related investigation involving Soichiro. Chūzenji acts as a stabilizing force within this group, balancing their diverse personalities with his grounded approach.

The character also appears in crossover media, specifically a collaboration with the mobile game "Onmyoji," where he features in the storyline for the original character Yato no Kami.
