"Little Demon, come give me a back rub."
The world's unrivaled Demon King of the present age knelt in humiliation, her long silver hair trembling.
She couldn't even imagine herself kneeling before a human boy. He was only as tall as her shoulder, and she could drown him in her arms!
Even more unimaginable was that the mother she should have killed had appeared again, becoming this boy's...
"Little Demon, show some restraint. You don't want your mother finding out that you killed her to claim the Demon King position back then, do you?"
Luo Tian was certain he had the upper hand. He would lead humanity to end this war between humans and demons.
Until... the silver-haired Demon King cast the one and only ultimate spell in demonkind's history.
"Luo Tian, I sacrifice myself. From this moment on, you are the Demon King!"
Then the young Demon King saw her former subordinates and even her mother bow their heads and submit to that boy.
"Huh??? Why? I was the Demon King back then, and I never got this kind of treatment! I won't accept this!!"
Lainis would return from hell. She would be reborn, become a human saintess, and kill that guy!
A hundred years later, Lainis would hold her child and remember the day, many years ago, when she was a saintess brought by the Demon King's army to the Demon King's castle to become his wife.
"Hehe, being the Demon King is still the easy life."
