In the center of Onigashima, Jakoku, where Enbizaka is located, a severed head hangs from an execution site. A monk traveling through the region wonders what kind of crime the head committed and asks the people; he learns that the owner of a clothing store and his family were murdered by the head. Questioning why the lovely woman of the tale killed those people, the monk notes that the head of Onigashima doesn't say a word.
The next day, the monk visits the site to perform the memorial service and sees a boy; questioning who he is, the monk learns that the child was the one who cut off the head at the site. He remarks that the woman was both sinful and pitiful before he joins hands with the monk and chants the rites. Noting that the woman was once a skillful tailor, the severed head in Enbizaka doesn't carry her scissors skillfully anymore. It's also noted that no matter how pretty the kimono, the severed head ultimately can't wear it without a torso.
The events alluded to in The Weathered Head at Onigashima are depicted in The Tailor of Enbizaka, showing Kayo's insanity and jealousy that led her to commit the murders. Her skill with scissors is also depicted in the song.
Onigashima is the name of a mythological Japanese island where oni, the Japanese equivalent of demons or ogres, reside; fittingly, the island of Onigashima is located in Jakoku, which is inspired by Japan.
While remarking about the song, mothy cited that a reason the song was made was because he had wanted to make more enka-style songs.
