Medeia despised kids.
She thought those little gremlins were annoying and noisy. They always asked too many questions, touched things they shouldn't, and cried at the slightest inconvenience.
There were times when she imagined throwing one into a hot cauldron, just to shut their mouths that wouldn't shut.
Sometimes she even wanted to let the monsters eat them alive, because she didn't want to waste her energy trying to save them.
But no matter how much she hated them, Medeia had never hurt them.
Maybe the reason she hated them was because their pure and innocent hearts reminded her of something she had lost long ago—
—Her own children.
To the Demon Lord, their children were nothing but a threat to his reign. Therefore, he decided to eliminate all of his offspring to secure his throne.
He had killed them without mercy and in doing so, he had stolen her chance to become a mother.
