Detectives These Days Are Crazy!

Keiichiro Nagumo was once a prodigy who solved cases as a student. Years later he runs a small agency with few clients, uneasy with phones and online forms. Mashiro Nakanishi shows up, declares herself his apprentice, and stays until he takes a job. Their days turn into a chain of simple requests that slide into arrests and chases. They search for lost pets, tail rivals, settle insurance mix ups, and step between shopkeepers and gangs when a local quarrel grows sharp. Mashiro produces tools and favors that keep the lights on while Nagumo tries to act like the man people still remember. A showy young detective circles them, a thief leaves playful notes, and a cat named Cerberus claims the desk. Hints about why Nagumo faded resurface in old contacts and a case that broke his stride. The story follows an office that learns to live on small fees and word of mouth as an apprentice becomes a partner.
