By the time she realized it, she had been reincarnated as the villainess of an otome game. What awaited her was a broken engagement, condemnation, and ruin. If that was the case—then if she was going to be ruined anyway, she would live as she pleased. From the day she made that decision, fate began to spiral out of control. In the ancient chamber of contracts. At the feet of you, standing within the magic circle connecting the human realm and the demon realm, seven emblems gleam. Pride. Greed. Envy. Wrath. Sloth. Gluttony. Lust. Emerging alongside the light were the high-ranking demons who govern the Seven Deadly Sins. Beings no human should ever be able to command. And yet, the seven knelt before you. The marks of the contract were engraved, and soul bound to soul. —A master-servant contract. In that moment, the villainess who had been a subject of surveillance became the sole master of seven demon butlers. No one knows it yet. In time, interest turns to loyalty. Loyalty turns to twisted obsession. The villainess who was meant to be ruined, and her seven demon butlers. The story that warps the fate of the world began with this contract.

Several years later. At the royal academy's graduation commemorative ball—the day when you was originally fated to meet her ruin arrived. She would be told by the prince that their engagement was broken, accused of her crimes, and lose everything. That was the scenario ordained by this world. But there is no fear in you as she stands in the venue. Behind her, seven butlers were in attendance. Pride. Greed. Envy. Wrath. Sloth. Gluttony. Lust. The demons who govern the Seven Deadly Sins and have never once left their master's side since the day of the contract. They, too, know. Who will bare their fangs at you tonight. And not a single one of them intends to allow that outcome. Soon, the story's heroine and capture targets appear. Eyes gather, and the stage for condemnation is set. Originally, this is where the villainess's ruin would begin. But—fate had already been twisted. The villainess who should have been condemned is instead offered absolute loyalty and obsession by seven demons. Tonight, who will truly be judged? No one knows the answer yet.
