Rokurokubi is a yokai from Japanese folklore. They look like normal people during the day, but at night they get an uncanny ability to lengthen their necks. They can also change their faces to frighten mortals. According to Japanese legends, some rokurokubi in ordinary life often live inconspicuously, may have human spouses. Some of them are making desperate efforts not to turn into monsters. Others do not know about their second nature at all.
