Anju is Karin's younger sister and she absolutely loves her, close to the point of possession. She has not quite awakened as a vampire though has amazing control over bats and because of that, she is obviously still somewhat sensitive to the sun, attending school on overcast days. Anju is very reserved, speaking in a quiet manner and wears a Gothic Lolita attire. Boogie-kun is her companion, whom she carries around and is her favorite of her dolls, something she enjoys collecting. She will do anything for Karin. In the anime, Anju's blood preference is jealousy when she awakens. In the manga, it's loneliness.
