One day, monsters appeared in the world, and reality turned into a contest between two factions: monsters and humans. Yun Ya, a human, was chosen to lead the monsters as their Demon King. He had to lead the monster faction to victory.
There was only one way to win:
[Eliminate all humans]
Yun Ya (species: human): ...Can I withdraw?
[Notice: If you withdraw, both the monster and human factions will die immediately.]
[Would you like to withdraw?]
Yun Ya cheerfully selected the option.
[No/No]
...Wait, why isn't there a Yes option????
...Hello????
[Notice] If neither side wins within the allotted time, both the monster and human factions will die immediately. There can be no draw.
[Countdown: 10 Y 000 D]
[The game begins.]
Also known as The Ugly and Beautiful Monsters
Theme: Only by working together can we welcome the rainbow of victory.
