City of Sin (Yanyu Jiangnan) - Vol 9 Chapter 136

On that day, due to the outbreak of an unprecedented and abnormal event, 41 students from class 2-7 of Shiromine Academy are summoned to a different world, one full of magic.

Separated and summoned inside a vast dungeon, where the only way to escape is to head to the deepest area, they are given the power of a Divine Protection 『Vocation』 as the only means of survival.

While some of them are brave, some just do whatever they want, and some harbor treacherous intentions, they all aim to capture the dungeon.

In this place, one person gained a 『Vocation』 whose skills are unsuitable for combat, attendance number 19, Momokawa Kotaro.

A boy with a small and lean build from the Literature Club wasn’t blessed with a physical ability, swordsmanship, or strong magic, rather he only had the 『Shaman』 vocation to rely on.

After being driven out of the group and left behind by his powerful classmates —– his survival instinct starts running at full throttle!

Pushed to the limit of survival in the different world’s dungeon, what starts with trusting and loving each other soon ends in killing and betrayal.

The most beautiful and gruesome battle royale has raised its curtain.

Here martial arts are no longer intangible legends. They have been passed on from generation to generation and from century to century. After the confrontation with science and technology, they have completely integrated into modern society and all kinds of martial arts competitions are taking place across the country as superiority among scholars are hard to reach a consensus but not as difficult among martial artists!

Starting from today, I am retired. But what should I be doing? I neither have the skills, nor the mind to do business, my only advantage is this pair of hands which have taken this world. What a headache…

Note: The usage of the term “retired” here doesn’t mean retiring from old age, work etc. It’s a specific term to refer to not involving oneself in the affairs of a certain society.

- Description from Novelupdates

The Devil’s Den was Cosette’s favorite webnovel that she had followed for three whole years. She waited for updates, wallow in those empty days during the author’s constant hiatuses, cry and laugh with the characters; it was already a part of her short life.

Cosette really wished that the novel would never end despite that she was terminally ill.

But after three years, The Devil’s Den finally came to an end. With a reader as invested as Cosette, she had mixed emotions about the ending. Not that the ending was disappointing, but what disheartened her was the ending of her favorite character; the villain Maxen Devilsin.

One year later, Cosette took her last breath only to wake up in the body of the stunning Cosette Blac; the villainess of the novel The Devil’s Den, her second favorite character after the villain.

Granted with the opportunity to live in the world of her favorite novel before the main story starts, Cosette had a plan.

That was to simp over the characters and save her favorite characters whilst hoping that the female and male lead still have their happy ending.

In a world that was already written and events that were expected to happen whether or not they wanted to, can Cosette change the course of their lives? Was overwriting the characters' fate could save them? Or would it just give them a much worse ending than what the author had given them?

Watch Cosette as she tried to become the superfan and give the dark-themed story some light.
