I, Takayama Aruto was summoned again in replay mode, keeping all of my past stats. This time, a large Hero’s Summoning was conducted which brought along the whole class.

The reality told me thus - that I would amount to nothing no matter what I did.
In order to change my pathetic life, I chose fantasy, instead.

Chrome was a magician in the hero’s party.

He fought the Demon Lord’s army alongside people like Irina, the lover who vowed to marry him in the future, and the hero, Yuno, who was his close friend.

They were all close companions. However, that was only in Chrome’s mind.

Amidst his despair, he acquired an unrivaled skill.

Now with this skill, he could exact revenge.

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?
