Keigo Kurusu

Serving as a dedicated police officer, this investigator relies on a mysterious supernatural diary to preemptively track criminal activities. This powerful tool provides crucial warnings about upcoming crimes occurring throughout his assigned prefecture, though its predictive abilities are strictly limited to his specific patrol district. Named after the Roman god of travelers, he uses these prophetic entries to stay one step ahead of danger, even as the full extent of the diary's simultaneous tracking capabilities remains a mystery.
