Barahime

Barahime is an evil witch. Her physical body was taken away by Kurohime 50 years ago, so she possessed Yuuka, a pretty girl.

The Kurohime Punishment Squad
At some point, Sword, in her weakened state, found Barahime and saved her. They, along with Ouka, Aika, and Saika, created the Kurohime Punishment Squad.

Materen
Barahime and the rest of the Punishment Squad clash against Himeko in the mobile fortress of Materen. There, Himeko kills Barahime for good, ripping her true body in half with the help of the Power Bullet while saving Yuuka.
