"...Well, transformations aren't all that unusual these days~"
My own dad, the previous Netherworld God, sealed me away for over a thousand years as soon as I was born?

It's a rule passed down through your ancestors. When the women of the clan grow up, they must marry the next successor to the position of Netherworld God~
"Wha... what?!"
