It is the age of Warring States, after the death of Toyotomi Hideyoshi. The various military leaders of the land have split east and west, and strive against each other for hegemony. The Eastern Army proclaims Tokugawa Ieyasu as supreme commander, while in the west, the commanders gather around Ishida Mitsunari.

Date Masamune, Sanada Yukimura, Honda Tadakatsu, Ootani Yoshitsugu... These and other heroes of the time prepare to take up arms. Some for ambition, others for their comrades. The stage is set for the curtain to rise once more over Sekigahara!

At least, that's the way it should be. However, these warlords get along unusually well with each other.
