Poisoning the World

She is the secret service's trump card, a poison specialist, but also a young and cute girl with a sinister temperament. Contrary to her sweet and innocent appearance, she can complete any tasks without the slightest hesitation. One day because of a incomplete black magic, she was sent into the body of a girl who was deemed as a waste of resources. What kind of change will she bring to this continent?

A certain bitter and hateful prince says," I believed she was weak and easy to bully, therefore I broke off my engagement. Only I didn't expect she is a poisonous shrew. I made an error of judgement."

A certain crown prince sighs,"She is such a sexy evildoer! Obviously, she has a frail and tender body, but I wasn't able to overtake her..."

Finally, a certain Ancestor hit the nail on the head,"She is just a bit two-faced!"

She answered, "You're just a big pervert!"

A certain Ancestor carried her into a room."Then, you are meant for me! A two-faced and a pervert, that's a perfect match!"
