Which Anime Adapts Mystery Tales From Popular Novels?

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline. On the day of her birthday, her body gave up and she died alone from exhaustion. Upon receiving the chance of a new life, she was reincarnated as the daughter of the Duke of Polvaros and acquired the prose of living a comfortable life ahead of her. Only she doesn't want that. She wants to work. Even if it's being a maid, a hired killer, or an adventurer. She will do it. The only thing wrong with Evy is that she has no concept of reincarnation or being isekaid. In her head, she was kidnapped to a faraway land… stranded in a place far away from Japan. So she has to learn things as she goes with as little knowledge as anyone else. Having no sense of ever knowing that she was living in fantasy nor knowing the destruction that lies ahead in the future. Evy will do her best to live the life she wanted and surprise a couple of people on the way. Unbeknownst to her, all her actions will make a ripple. Whether they be for the better or worse.... Evy has no clue.

As the news broadcast reported a random serial killing near my residential complex, I knew—I had been reborn once again. In my first life, my husband insisted on going out in the middle of a snowstorm to buy weapons for self-defense. I locked every door and window, waiting at home, anxiety clawing at my chest. I never imagined the killer could pick locks. Before I could even react, a blade plunged into me, and I died on the couch. In my second life, I didn't hesitate. I hid in a concealed storage room, holding my breath. But the door was still pulled open. A man wearing a rabbit mask stared straight at me. "Found you," he said. In my third life, I ran to the police station. I rushed inside and told the officer on duty that the killings weren't random—that the murderer was coming for me. They looked at me like I'd lost my mind. Then my husband arrived in a hurry and took me away. But the moment we reached our front door, a heavy hammer smashed into the back of my head. Through the blinding pain, I forced my eyes open, but I never saw who killed me. Now, staring at the grave expression on the news anchor's face, agony surged through every inch of my body. Rebirth isn't a reset. The damage accumulates—and sooner or later, it will torture me to death. Without hesitation, I walked into the kitchen and set a pot of oil to heat. And I waited… for the moment the lock began to turn.

I found an old quill in an antique shop and decided to buy it since I have always wanted to write with quills. However, as soon as I touched the quill to the paper, I was transported into the book. I wasn't the only one there, though three males who always hide their identities behind masks were in the book with me. They claim the quill belongs to them, and I must return it. Since I refuse, they follow me into every book I go into. One day, I was debating which of my mature books to write when I accidentally spilled the ink onto my book, 1001 Dark Tales. The only way they'll help me out of the book is if I give the quill back, and there is now a fourth. As I go through more of the book with them, I start noticing things. Things I had never planned for in my book, and it concerned me because even though I hadn't written those parts yet, none of the other stories I had used the quill on had ever gone that off track. However, when we tried to leave the book, it wouldn't let us back out. It seems we're stuck in the book until we finish all 1001 Dark Tales.
