OVA
Description
Reiji Tokisaka operates as a private detective in 1956 Tokyo, shaped by his past as a Japanese Army soldier and postwar police officer. Haunted by lasting guilt over the unsolved case that claimed his fiancée Yukiko Miyama six years prior, he resigned from the force. This trauma fuels his relentless pursuit of violent crimes, particularly serial murders. He resides in Suginami with his younger sister Yukari Tokisaka, though casework often keeps him absent. Their home holds a substantial collection of historical books and documents inherited from their late scholar parents.

Reiji accepts brutal murder investigations, frequently at the request of former colleague Kyozo Uozumi. His method relies on meticulous evidence collection, crime scene examination, and inference-based deductions recorded in a detective notebook. Probing serial killings linked to Ouba Girls Academy—where Yukari studies—he goes undercover as a history teacher. This position allows him to investigate the school's criminal ties while concurrently pursuing a request from student Touko Kuchiki to find her "true self." His investigation reveals connections between Touko's past, the murders, and his fiancée's unresolved death.

Physically slim and pale, Reiji stands 178 cm tall with brown wavy hair parted in the middle and black eyes, typically dressed in suits and neckties. His personality blends pragmatism, sharp observation, and a blunt demeanor with underlying kindness and protectiveness, especially toward Yukari. He exhibits dry wit and teasing banter with acquaintances like Tsuzuriko Yosomiya, whom he nicknames "Tojiko." His hobbies include reading historical novels and frequenting Café Moon World, interacting with owner Kyoko Hazuki—a widow who shares his understanding of loss—and waitress Hatsune Amemiya. Profound loneliness shadows his resilience, stemming from his traumatic past.

Reiji's development centers on confronting cyclical violence and personal trauma. His investigations force him to reckon with wartime experiences, his failure to save Yukiko, and postwar Japan's societal denial of brutality. Key relationships—including his growing concern for Touko Kuchiki and tentative connections with Kyoko and Hatsune—highlight his struggle to move beyond guilt. Resolving the murder case exposes multiple killers: novelist Shinji Mamiya and the elusive "Rokushiki Makoto," though endings vary. In the true ending, he fails to save Touko from mutilation and captivity, reinforcing themes of unresolved grief. This conclusion sets the stage for his continued investigations in subsequent stories, persisting in his pursuit of closure amid new tragedies.
