Reincarnated as the Villainess Older Brother?!

[Disclaimer: the cover picture isn\'t mine.]

My name is Damien Herald, the eldest son of the Duke Household of Herald. Once I heard of my little sister\'s engagement to the crown prince, I suddenly regained memories of my previous life.

I then learned that in my other life I had suddenly died and was reincarnated into an otome game my past life\'s little sister was obsessed with, ~Our Fateful Encounter~. And that in this life I\'m the villainess\' older brother, wait doesn\'t it mean my current little sister would cause the destruction of our family!

Now how do I stop my current little sister from leading to our family\'s downfall!?
