In regards to the maiden, there must be an important man participating in the gang rape, in other words, that man must be related in blood to their wife or lover, mother or daughter, younger sister or older sister, and the like, and after the gang rape, if a pregnancy occurs, Hime Iwanaga's anger is abated, and a good harvest and safety upon the region will be promised.
