Tale of Yashima is loosely based on the Sengoku era of Japan. The power of the shogunate has crashed and the daimyos of Yashima are fighting for the survival of their clans and control of the land. However, they're not the only ones. Yashima is a land where both man and yokai co-exist, and not always peacefully. As the daimyos are busy with each other the yokai are also planning their next move. The Night Parade is coming, and not everyone is going to survive.
