[Transformation + Invincibility + Transformation + Western Fantasy]
"Miss Brave, do you want to escape alone, or follow me to the Demon King's castle to protect the world? You choose one!"
Lucia, who had just traveled through time and became the Demon King, met the defeated brave lady Vivian, and decisively gave her the option of death.
"As long as you don't destroy the world, I can be a kitten for you. Please... Let the world go..."
In order to protect herself, Vivian began to speak arbitrarily, but she didn't expect that the Demon King Lucia would become interested.
"I thought you only cared about yourself, but I didn't expect you could go so far as to save the world."
"Miss Brave, please call me Master first."
