A retelling of a Japanese mythology recounted by the Nihon Shoki, in which the moon god, Tsukuyomi, was sent by his sister/wife, the sun goddess, Amaterasu, to visit Earth. He was welcomed by the goddess of harvest, Uke-mochi, who began to prepare food in such a disgusting manner that Tsukuyomi got offended and killed her. When Amaterasu heard of this, she banished Tsukuyomi, resulting in the separation of day and night.
I changed some details of the story to allegorize the themes of sin, guilt, and the yearning for redemption, although these changes are not completely without textual basis. In several other tales in Japanese mythology, Uke-mochi is often associated with or is identical to Inari, the deity of agriculture and of foxes. Kitsune (Sky Fox) is another prominent character in Japanese folklore. They are masters of illusions--usually benevolent but can also be malicious (it depends on the story)-- and serve as an allegory of temptation in this ballad.
