Divided into four installments.
A dark and dreamy series about a vampire girl whose sacred duty is to return all stray demons (shinma) to the darkness. She is aided by a dark and scary servant named Larva, and constantly harrassed by a female spiritualist named Himiko who's out to get her. Excellent animation with a genuinely creepy feel. Miyu is great - behind her icy cold seductive stare and dangerous supernatural power hides a sad and frightened little girl. Great spooky fun.
