She is a top-class spy, a poison specialist, but also a young and cute girl with a sinister temperament. In spite of her sweet and innocent appearance, she can complete any tasks without the slightest hesitation. One day because of an incomplete black magic, she was sent into the body of a girl who was deemed as a good-for-nothing. What kind of change will she bring to this continent?

A Prince said with bitter hatred, “I thought she was weak and easily bullied, therefore I broke off the engagement. I really didn’t expect she is such a shrewd girl. I made an error of judgment.”

The Crown Prince deeply sighed, “She is such a sexy evildoer! Obviously, she has a frail and tender body, but I am not able to overwhelm her…”

Finally, an Emperor hit the nail on the head, “She is just a bit two-faced!”

She answered, “You’re just a big pervert!”

The Emperor carried her into the room and said, “You are predestined to be mine! A two-faced girl and a pervert are a perfect match, right?!”

In the original lines of the novel, I was a villainess—used as a political tool by my father and older brother—who ended up dying at the hands of my future husband.

Year 2022, December the 1st. This was the day it all began.

Labyrinths had started forming all around the world, hundreds and thousands of people lost their lives as casualties.

Mutations followed after, occurring amongst the people, they began awakening super powers, the same for animals.

However these mutations brought along a virus. It quickly spread amongst the dead as they began to rise. Humanity had begun its fall.

Gray who had given up all hopes of living life, was granted a system with a special ability. On the very same day, of the outbreak, he was consumed by a labyrinth.

By the time he had gotten out, a week had passed. It was hell all around. A virus had broken out from the mutations, the dead were walking and spreading this virus.

However this was only the beginning.

Over time the mutations began to evolve and people learnt that the through the cultivation of their powers, they could improve their abilities.
