A vampire who tries to act mysterious, cool, and intellectual like the ones in movies, but in reality, she is very timid, clumsy, and a glutton. After being forced to clean the art room with Shinta Otori, she ended up revealing her true self. Since then, she has been practicing how to suck blood with the help of Shinta and a few other friends, gradually opening up to everyone. When she gets startled or hungry, she shrinks in size, and her weight seems to decrease significantly as well. Unlike vampires in other works, there are no specific dietary penalties mentioned, but her efficiency seems quite poor. Her recent favorite foods are udon and the Otori family's miso soup. She isn't picky and even eats black garlic without issue. Because she can't suck blood properly, it's said to be quite painful when she tries, but Shinta and Eiko—who both adore her—let her practice on them skillfully. As a vampire, she can fly and possesses great strength, but she is weak to rain and doesn't show up in photos. Sunlight can be warded off with just sunscreen, as she even joined the others on a trip to the beach.
