8000 female warriors inspired by Tale of Heike and the legendary tale of a woman named Tomoe Gozen.

Tomoe Gozen (巴御前) was an onna-musha from the late Heian period of Japanese history. She served Minamoto no Yoshinaka during the Genpei War and was a part of the conflict that led to the first shogunate. Her family had strong affiliations with Yoshinaka.

Her story in the Tale of the Heike influenced several generations of samurai. Tomoe is often celebrated in books, music, poems, films, historical novels and culture in general.
