You are a nameless ninja attempting to rescue a princess who has been kidnapped by the monster overlord, King Tengu. The game actually has no dialogue written in it at all, making it all about the action. Armed with only his sword, he must travel the land in order to obtain special skills that will allow him access to King Tengu. The ninja will find elemental magic attacks along the way. These will increase his damage potential and he'll also be able to buy bombs and shurikens from the shops, further increasing his deadliness.
