You play Kazamuru, a great warrior who challenges the clan to a fight in order to rescue the princess. However, he can't rescue the princess unless he finds the five scrolls in the thirteen areas of Ohkami.

On his quest, he must defeat various ninjas such as Kuno-ichi and Ninniku, as well as fire-blowing ninjas, slashing ninjas, and footloose ninjas.

You'll explore grassy fields, shrines, river banks, towns, and the castle itself. Some of the steps have varied gameplay. For example, you must avoid boulders in Step 2, must use logs in order to cross a river in Step 5, avoid being trampled on by horses in Step 7, and scale a cliff in Step 9.
