The collection is called Kamisama no Seppuku. Kamisama in this case means Goddess, but it refers to any kind of deity, as Japan has more than one God. Seppuku is a Japanese suicide ritual, mostly know as Harakiri in the West. It was originally performed by Samurai as a way of dying with honour and it has been romanticised as a beautiful way of dying by many. The collection then means the Suicide Ritual of the Goddess. It is basically the story of a Goddess who is punished by other Gods for falling in love with a human.
