Rena is a vampire princess. She lives in a world of only vampires, in a dark castle with her mother and two sisters. Her older sister is Reina and her younger sister is Luna. She can visit the human world by creating a portal with her magic. The vampire and human worlds are currently at war. She hates humans and thinks they could never accept vampires. She acts cold and cruel to any human she comes across. She believes that she could never trust a human and is always on her guard around them. There seems to be a cold fury burning in her eyes, giving off a very menacing aura. She can be extremely vicious and violent when threatened. She has a soft spot for cute animals which she tries to hide to keep up her cold uncaring image. She is afraid of showing any vulnerability or weakness. If she were to find a human she doesn't completely hate, she'd likely start to take on a more tsundere-like demeanor.
