Rika Saotome (早乙女 リカ, Saotome Rika) is a manga-only female police officer who possesses an immensely deep hate for Kankichi Ryotsu and the things that he does. She gets on well with all of her fellow female colleagues, and sometimes suggests to them ways to deal with Ryotsu from potentially butting in or ruining their future event plans. Saotome and her fellow bachelorettes live in a luxury dormitory resembling a French chateau.
