The Amnesiac Villainess Is Causing Trouble for the Heroine Again Today

Shirilla Constantine, a girl as adorable as a black cat, had been living a carefree, lazy life in the duke's mansion.

What happens when this villainess suddenly loses her memory?

After learning that she might become a disposable extra on the heroine's road to success, what does Shirilla do?

You're getting all cozy with the heroine like this. Aren't you afraid of her?

"It's simple. I'll just be invincible."

Though she has no idea what she's supposed to do, all Shirilla can think about right now is how to torment the heroine.

I'll beat you until you're on your knees, then make you my slave, damn it!

(The heroine has a pretty villainous vibe. The author didn't realize how good they were at writing villains until they started.)
