The newly opened Suehiro Detective Agency is comprised of laid-back manager Hisago, dog-loving chief investigator Shimeki and administrator Tsukumo. With very few paying customers, the three protagonists are free to spend their time bickering with and teasing one another, setting each other up in matchmaking schemes and looking for lost pets. Shimeki also has to contend with his knife-wielding ex-wife and the overly dependent little brother he’s just been re-united with.
