After accidentally transmigrating to ten thousand years in the past, an evil witch found herself trapped forever in the Witch's Tower.
To escape, she began constantly tempting and cajoling adventurers from all over the world into challenging the tower.
But every single one of them met with failure. A thousand years later, the witch was still mired in despair, unable to move on from the past.
Then one day, a young man who was both a prince and a hero rode up alone on a white horse and stormed the Witch's Tower.
"Brave human, if you agree to form a soul contract, I can grant any wish you desire~"
"Really?"
"Really! Whether you want wealth to rival a kingdom's or enough power to stand atop the world, I can make it happen!"
"All right!"
As the man formed the soul contract without hesitation, the witch burst into laughter.
"Hahaha! Foolish human, this is a slave contract! From now on, I am your master!"
"You'll have to do everything I... Huh? Wait, this contract is wrong!!"
"What... what have you done to me?!"
In response to the witch's alluring, flustered voice, the man simply smiled.
"I just used a little trick to reverse the master-servant relationship."
"Now, as your master, I order you to become my wife and bear me ten children!"
"Wha-what?! Become... your wife?!"
"Have... have children?!!"
