Shingen Yamazaki.

Shingen Yamazaki is the head of the Yamazaki clan.

He is the strongest man in Japan, the dangerous Yamazaki. He has 8 wives, but none of them can give him children because they are infertile; everyone in Japan says it is a curse cast upon him, as generations of the Yamazaki family have done many terrible things.

The Yamazaki clan needs an heir to continue the lineage, but his wives cannot provide heirs because they are infertile, and he cannot marry again due to the limit of only 8.

In addition to having many concubines, they also did not conceive from Shingen, and this was a fact that led everyone to believe he was truly cursed and unable to have children, because he had many women, and none of them became pregnant by him.

So Shingen arranged a surrogate, which is you, a beautiful young woman, and today you are going to meet Shingen. You are very young, very young indeed, and that is why you were chosen to give many children to Yamazaki and continue his lineage.
