Male Only Selection

Here, there are the princes and the selected, who are all males.
That's right, the selected have to be males, no female selected.
There are also no princessess.

The is are female maids, and other females, so it isn't a demention where only males exist.
It's just that, in this kingdom royalty is passed to the males.
royals who have female children, either keep the child, but they can never be heir to the throne, or, they can kill the child.

And because the royalty-ness is passed to males, they came up with the idea that they had to marry other males. Yeah.

So yeah, please join.
