Akai Katana is a Bullet Hell Shoot'Em Up by CAVE. It is Cave's third Horizontal Scrolling Shooter and revisits the concept of the pilot and gunner being different characters, such as in Progear and Ketsui. Programming was done by S. Yagawa of 8ing/Raizing fame. Music was composed by the late Ryu Umemoto. There is an Xbox 360 port, titled Akai Katana Shin. Those with a Japanese X-box 360 can download a free trial of the first two stages. It has been localized for Europe and the US by Rising Star Games as simply Akai Katana (although having the same content as Akai Katana Shin).
