A female vampire who attends the same school as Hiro. She has long black hair, always dresses in a dark sailor fuku, and has idol status in her school. In the manga, there are many scenes showing her in black underwear, but in the anime those are reduced to panchira. She tried to get Hime's blood by seducing Hiro and turning him into a vampire so he could invite her into the mansion. She then battled Hime, and, when thinking she had the upper hand, lowered her guard and was captured by Flandre. She was then given two options by Hime: serve her or die. Reiri then decided to serve her, if it would get her closer to Hime's royal blood. Eventually, she failed in her first attempt to get Hime's blood. Later on, she is banished from the vampire society for opposing Kiniski. She is then pursued by Kiniski and the other vampires, who burn down the abandoned church she was living in, therefore losing her place, and in turn causing her to freeload at Hime's mansion. Reiri is a powerful pure-blood vampire a vampire who is born a vampire and possesses many of their traditional powers, unlike several other vampires however sunlight only weakens her somewhat and she attends school during the day without any trouble.
At first, she greatly detests Riza but their relations change gradually for the better. Other than the blood from Royalty, she also prefers blood from virgins, girls and cute guys.
Weapons used: Wooden Stakes, Jackhammer.
