Nukekubi (抜け首 or ぬけくび, Nukekubi) appear to be normal human beings. But by night, their heads detach from their neck smoothly from their bodies and they fly about in search of human prey. These heads attack by screaming to increase fright , then closing in swiftly and biting their victims.
This variant type of rokurokubi, known as the nukekubi, is similar in most respects to the first type, except that the head detaches itself completely from the body rather than stretching out on an elongated neck.
Nukekubi are often much more violent than rokurokubi. Because their heads are detached, they can travel farther distances than the rokurokubi’s head can. Additionally they often possess a thirst for blood. The flying head usually sucks the blood of its victims like a vampire, but occasionally brutally bites humans and animals to death.
Uncured, this curse has the potential to tear a family apart, particularly due to the more violent nature of this variant. A diagnosis reveals that nukekubi suffer from an infliction similar to somnambulism; only instead of walking about at night, the patients entire soul and head depart from the body. Treatments for the curse of the rokurokubi and nukekubi have been long sought after, particularly because these women can often pass their curse on to their daughters, who begin to shows signs of it as they mature. Girls afflicted with this curse were usually sold off to live in brothels or human circuses, or else forced submit to an honorable death by suicide to preserve their families’ honor.
A famous account from Echizen tells of a young woman afflicted with the curse of the nukekubi. Her head flew about the capital city at night, chasing young men through the street and all the way back to their houses. Locked out, the head would scratch and bite their doors and gates during the night, leaving deep gashes in the wood. When the young girl eventually discovered her curse, she was so ashamed that she asked her husband to divorce her. She ritually cut off all of her hair in repentance for her curse, and then committed suicide, believing it was better to die than to live the rest of her life as a monster.
According to lore from Hitachi, a man married to a nukekubi heard from a peddler that the liver of a white-haired dog can remove the curse. He killed his dog and fed its liver to his wife, and sure enough she was cured of the affliction. However, her curse had been passed on to her daughter, whose flying head took to biting white dogs to death. Other accounts claim that by removing the sleeping body to a safe place during the night, the head will not be able return, and will eventually die – however this is not a cure that most families are happy to try.
