From Monogatari. Speaks with Old English. Brazen & self-adoring, laughing with "kaka" rather than haha. Long blonde hair, yellow eyes, pointy ears, sharp fangs. Appears 8 but claims to be 500 (actually 598). Loves Mister Donut.

Once a princess named Rola, cursed to drive others to take their life. She then adopted the name Acerola before willingly becoming a vampire under Deathtopia Virtuoso. Now, with most powers lost, she survives on her human master’s blood and resides in his shadow by day.
