"Akai Katana" is a side-scrolling shooting game released in 2010 in arcades. A port was later made in Japan for more advanced hardware under the name of "Akai Katana Shin", and thanks to the 16:9 screen ratio, the game became even more intuitive.

Each game will ask you to use different tactics, so prepare yourself.
