[Double male protagonists + no system + non-cool text + villain + both sharp and sweet]

P.S.: "Those with upright values, please watch with caution."

I woke up and found myself transformed into the villain Demon King Muzan Kibutsuji from the anime Demon Slayer?!

But now that things have come to this, in order to survive, Mo Yunchuan can only start to plan a way to save his life!

From now on, I will help anyone who has anything to do with the Demon Slayer Corps and try to win their favor. I must make sure my favorability goes to the hilt!! And I absolutely won't do anything stupid.

However, strange things also began to appear. Jiguo Yuanyi was resurrected and even wanted to get close to the Ghost King Mo Yunchuan. Why did he resurrect? This is a question.

Moreover, who is Kawano, who can transform between a cat and a human? Why did he appear? And why doesn't Mo Yunchuan remember him?

Then, why does this pair of bodies also have an unknown soul? Could it be that two souls simultaneously traveled through time into one body?

And...if being born is wrong, then will the choices we make also be wrong?

Why are there missing memories and extra memories in the brain? Why are there extra memories? And what will they become after they are reassembled?

What is sealed in the deepest part of his memory? Why doesn't he know? Why does he feel in danger?

Does the world really exist? Is it man-made? Can you accept it?

A mirror can reflect yourself, but is what is shown the real you?

Are you willing to destroy everything to achieve a goal?

What is good and what is evil? How can we distinguish and define them?

Are there perfect people in this world?
