Rami-chan no Ōedo Sugoroku: Keiō Yūgekitai Gaiden

Rami-chan no Ōedo Sugoroku: Keiō Yūgekitai Gaiden (蘭未ちゃんの大江戸すごろく慶応遊撃隊外伝; Rami-chan's Big Edo Sugoroku: A Keio Flying Squadron Sidestory) is a 1998 video game for the PlayStation. Developed by Victor Interactive Software, it is the third and last game in the Keio Flying Squadron series, and was released only in Japan. While the first game is a side-scrolling shoot 'em up and its sequel, Keio Flying Squadron 2, is a platformer with shooter sections, the third game is a party game.

Like the first two games, the third game refers to Japanese culture, both ancient and modern simultaneously.
