Sylvia  

Princess Sylvia, シルヴィア

The princess of the royal family, who is Himes older sister, is depicted wearing a dress while being blindfolded, gagged, and bound by leather straps in a restrained position. A tap has been installed on her to collect blood. She was pleased to learn that Severin had passed away but felt slightly disappointed that she didn't get the chance to kill him herself. Despite this situation, she remained unperturbed. Later, Micasa freed her and she joined the Royal War alongside Micasa as her new blood warrior.
