Japan has entered the Warring States era following the death of Toyotomi Hideyoshi, and its military leaders have divided into eastern and western camps competing for control. The East rallies behind Tokugawa Ieyasu, while the West gathers around Ishida Mitsunari. Figures such as Date Masamune, Sanada Yukimura, Honda Tadakatsu and Ootani Yoshitsugu ready themselves for Sekigahara, some driven by ambition and others by loyalty. The twist is that these rival warlords are on remarkably friendly terms. Adapted from a mobile otome game, each ten-minute spot opens with about three minutes of animation, followed by voice cast members taking on missions and a short informational segment.
