A young orphan named Biwa is taken in by the powerful Taira Clan—also known as the Heike—after their leader witnesses her extraordinary psychic abilities. Unfortunately, what she predicts is a future of bloodshed, violence, and civil war. Inspired by the 12th-century epic tale Heike Monogatari.

Villain or hero, Taira no Kiyomori changed Japanese history forever 900 years ago. Without ever knowing his real father, Kiyomori was raised as a samurai. Together with his stepfather, he wiped out piracy along Japan's western coast, becoming a full-fledged warrior samurai. In an age when samurai were looked down on as members of the lower class, Kiyomori was skillful at winning the hearts and minds of the people. By rounding up surrendered pirates and achieving other successes, Kiyomori eventually became the de facto ruler of Japan.
