Despite lacking the ideal skills for his role in the Metropolitan Police Department investigative team, Totomaru Isshiki's unwavering desire to solve murders and help others drives him forward. Seeking advice from a senior officer, he is directed to the enigmatic retired detective, Ron Kamonohashi, who disappeared from the public eye five years ago. Expecting a composed and professional mentor, Totomaru is surprised to find Ron as a disheveled and unreserved eccentric. Years of solitude have transformed him into a different person, and he initially refuses to help. However, he eventually relents and enthusiastically joins Totomaru in a serial murder investigation. Ron's retreat from the detective world was due to something beyond his control, rather than a lack of interest. Totomaru's arrival may be the missing component to reignite Ron's passion for his former calling. Together, the determined officer and unconventional detective tackle every mystery they encounter.
