One day, a lord of the spirit world is gravely injured. The head of a merchant family, Kageaki, happens upon and assists him. In return, he is gifted a celestial maiden, Juju, that lays eggs. It is said that such eggs are elixirs that can cure any disease and thus, to save his sickly little sister, Kageaki proceeds to inseminate the maiden time and time again.
While burdened with pangs of conscience he is attracted to the maiden. Likewise, while unwilling, Juju cannot resist the pleasure of sex and yearns for more. A pure love tale about the awkward circumstances under which their love for one another grows.

There is a TL and R18 version.
