A young police officer who assists detective [Oniyama](https://anilist.co/character/273456/Dogusaburou-Oniyama). Momo is a peppy, energetic young woman whose appearance defies her capabilities. Though more easygoing, Momo still shows dedication to her profession and shows excellent capacity to work as a team in order to apprehend [Joker](https://anilist.co/character/121152/Joker). She has no problem thinking of both work and leisure simultaneously—though work sometimes falls on the wayside during some Joker-related heists.

In the story, there is nothing in the world that the mysterious phantom thief Joker cannot steal. He goes after one treasure after another in unpredictable capers with seemingly miraculous tricks.
