The Madam of Yotsuya Q is a hidden boss found by taking a secret path on this game version's exclusive stage, Amusement Park. She acts as a replacement for Yoshiwara Dayuu, with a more comical-like appearance and a toned-down attacking pattern due to being faced much earlier in the game. She carries a crystal ball, which serves as her weak point.
- This boss is based on Q-Taro, the protagonist of the Obake no Q-Taro manga.
- Her name is a reference to Yotsuya, a neighborhood in Shinjuku, Tokyo which is famous for its ghost stories.
