Momo Shirai 白井モモ

A young police officer who assists detective 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. She has no problem thinking of both work and leisure simultaneously—though work sometimes falls on the wayside during some Joker-related heists.
