7 Blades is based on the 1990 film Zipang, directed by Japanese filmmaker Kaizo Hayashi.[1] The game takes place in mid-17th century Japan, during which the Tokugawa shogunate was gaining power. The game is set on the man-made island Dejima, which the Japanese government is using to house Western foreigners and were a Christian group is trying to separate from the rest of the country.[1][2] The main character is Gokurakumaru, a violent mercenary, and poor womanizer. He travels with his gun-wielding love interest (Oyuri) and sidekick (Togizo). The latter provides comic relief and holds the swords as Gokurakumaru collects them one by one.
