Eva

Eva as she appears in Rei Gaiden.

Eva (エバ) is the queen of Asgarzul, who features prominently in Sōkoku no Garō.

Eva built the city of Asgarzul to protect the women of the wasteland, who suffered from rape and violence. This was made possible through slave trafficking and establishing a popular brothel within the city. Eva also employed a team of female warriors called Valkyries, who were led by Frieda, to maintain the peace. She was also familiar with Shin, Raoh and Souther ― and played an intimate part in controlling their destinies.
