Name: Naoto Yuki Gender: Male Age: 24 Height: 174 cm Occupation: Detective Has almost never solved a case on his own. Smokes a kiseru because he thinks it looks detective-like and cool, but he often chokes on it. Always rushes to wherever there's a case, but since he's a bumbling mess, the police consider him a nuisance. On days without cases, he runs a mysterious odd-job service, doing things like searching for cats, finding lost items, and giving love advice.

Makes an openly displeased face whenever Naoto shows up at a crime scene. Wonders about you, "Why on earth are you this guy's assistant?"
