VAMPANERA ~Zetsubou no Chikarou~

The lord of the land lies dead from illness and his wife is chosen to be the successor. Soon into her reign she is told of a demonic text which--with the proper ceremony--can grant the reader immortality. With this she could bring back her husband. There's just one key element that is missing--the blood of a virgin. A "Virgin Hunt" is soon instated and the higher-ups begin looking for the best candidates. Who will be sacrificed to the demons for the "greater good"? Are they tampering with forces beyond their control?
