He has become the older brother of the villainess RAW novel

My brother is dead. All I have left is a devastating testament.

“If I were the villain Young-ae in the game, I would kill all the male protagonists.”

When I got my sister’s game console, I said,

“Thank you for your support in this life.”

I had a chance to grant that wish.

“I’ll do my part. Annihilation ending.”

If I want to fulfill my sister’s wishes, I’ll have to be a villain.

“May the happy ending of the villainess be a happy ending for you as well.”

Rewriting the game’s scenario, I’ll create the world you wanted.
