ChangeUrbanEasyLost Horse [The second female lead is a paranoid guardian with yandere traits] Rebirth is a very happy thing. Becoming a demon king is double the joy. Su Yin originally thought that he could punch the brave and kick the gods. However, she met the pervert - the human sword master Parea! One sword! Her huge demon king's true form was reduced to ashes, her magic power was lost, and she turned into a soft and cute white-haired lolita. "There will be no way for people to survive!" The autistic Su Yin ran to the human world and decided to die. As a result, as soon as he lay down, a beautiful woman grabbed the back of his neck. "What a cute child, you will be mine from now on~" Parea's eyes flashed with morbid enthusiasm. Su Yin trembled. Isn't this the female devil who hacked herself to death? !

From then on, during the day she was a well-behaved loli who ate and drank tea in the arms of the Sword Master, and at night she was the Demon King of the Abyss who quietly regained his strength! "My majestic Demon King... Well, don't be so shameless! For the sake of this strawberry cake, I'll give you a hug today!"
