When I regained consciousness, I found myself in an otome game. I would quickly head towards destruction. It made no difference whether it was a good ending or a bad ending. I became the character known as, “Mariabell Tempest,” the daughter of a pedigree family. Despite possessing an unrivaled level of beauty, I had the worst personality, that of a villainess.

Nevertheless, I was conscious, but was unable to make any actions as I was completely in auto-mode. In the first playthrough, I was extremely flustered; on the second playthrough, I was despairing; by the third round, I had already given up. And now, the fifth round has already ended. For the sixth round, for some reason I had become a young girl and regained the ability to move and talk. Eh, what the heck is this?

If you don’t want to be destroyed yourself, you have to destroy them first!

The heroine? The prince? Shaming her family? Being exiled from the country?

If only a bad end is destined for her, then she has to crush it through sheer firepower!
