Jaku-chara Tomozaki-kun - Volume 2 Chapter 1 part9

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…

“What should I do with your tantrums? I’m too busy right now to be by your side.” Well, since entering the dungeon, I hadn’t really paid proper attention to Cha Sahyeon due to being occupied with various things. It was a golden opportunity to make my face known by Kwon Taehyeok and Ryu Seonghyeon, the targets of the main quest, not to mention the unexpected participation of the Ronic Guild in the raid. Cha Sahyeon seemed to have caught my playful murmurs as his shoulders trembled. Eventually, I heard his subdued voice: “…Don’t go.” “What?” Leaning against my shoulder, Cha Sahyeon stared at me intensely. “Don’t go.” “…!” For a moment, a strange light seemed to flicker in Cha Sahyeon’s green eyes directed at me. Simultaneously, a loud notification sound echoed around us.

Ghosts are now commonplace. Some people now have three heads and six arms. Some people have obtained martial arts techniques and ordinary people are now just cannon fodder.

Fortunately, I have acquired an ability which can make various items mutate.

books into martial arts or cultivation manuals,
