This Life, Dedicated to You

My dear, lying dead underneath my feet. The one who gave my meaningless life meaning. People called you the devil, a horrid beast.

If you are the devil, then I will throw away my humanity.

If you are in this world, my love, then I don't care who is in my way, who you are, or who tries to dissuade me. I will find you, and I’ll lay the body of your enemies at your feet as people cry out your name in reverence.

After a deal with a dark entity, Callisto transmigrates into a world of an otome game she saw in her first life with one goal in mind: Kill the god of the world Lux, and live happily with her love. Unfortunately, she ends up in the body of the villainess, Cordelia Azel, who is hated by everyone for her cruelty. But for Callisto, who walks a path towards destruction, all she needs to do is avoid death, long enough to complete the end of her deal. As she tries to live a life clearing up Cordelia's mistakes though, the love interests keep trying to get close to her? How bothersome...
