野ざらしの首、鬼ヶ島にて (Nozarashi no Kubi, Onigashima Nite)

Background
If I hadn't forgotten... The monk Gakusha(Gackpo) is visiting Enbizaka on Onigashima. He comes across the severed head of a woman who had killed a draper and his family. Next day, he prepares to hold a funeral ritual for her as monks do and he meets a young boy named Kokutandouji(Len) and he reveales that he is her executioner. Kokutandouji admits that while the woman was sinful, he feels sorry for her and they pray together for her soul.

This song was released on the Seven Crimes and Punishments album as an answer song to The Tailor of Enbizaka.
