With Gacha being the Eternal Void - Chapter 6 - . A Great Opponent[Edit]

There was a Senior Brother and a Junior Sister. One of them was transmigrated to this world and had cheats while the other was the reincarnation of a Great Emperor.

A villainess known by all as a wicked woman who has done all sorts of evil deeds—Ducal Lady Violet.
She regained her memories of her previous life after she fell into a lake and almost died.
The very moment she woke up, she immediately visited her father, Duke Everett, and asked one thing.

“Please confine me to the annex.”

And so, she imprisoned herself there.
Now that Violet was secluded away from the world’s criticism and reproach,
She immersed herself in her previous life’s memories and started painting them.

“What the hell are you up to this time?”

Everyone was suspicious of just what she might be scheming.
However, the misunderstandings surrounding her gradually got resolved one at a time…

“A cheat system? Do you take me for a fool? Nowadays, where can you find such a good thing falling into your lap? Scram from my head. Is this is new kind of fraud? Or is this a murderer training system of aliens that contains the ability of hypnotism?”

“No, I am the chaos that whispers from nothingness, the nightmare of all living beings in the Southern Ten Stars, the successor of the unparalleled God and… your elder sister.”

“…I only have a younger sister, I don’t have an elder sister!”

“No, you have one. I am an illegitimate daughter. It’s just that your dad didn’t inform you.”
