I'm bombarding the Supernatural World with my firearms - Chapter 1 - - No Tolerance for Cowardice!

JoJo?

No, this is Dio!

After crossing, the protagonist is examining his new identity aggressively— Dio Brando, a British and Chinese mixed-race coach ratio!

But wait a minute…

This is the Marvel Universe? How long will it take for Thanos to reach the battlefield?

By the way, I have a cheat!

Star Platinum, The World, Crazy Diamond, Killer Queen, Gold Experience, King Crimson… All for me!

Ding, hello new player, your first Stand has been drawn.

Looking at the ‘Little Tomato’ who was smiling at him, as the only Stand User in the Marvel Universe, Dio was speechless, then lit a cigarette silently, looked up at the ceiling, exhales smoke, it’s just a mystery how life is so harsh!

As a promise, he went out into the world as an assassin. 3 years later, after becoming the Supreme Assassin, he gave up on everything he had and returned to the ranks of ordinary people. But one day, Kismet, a mystical game created by the National Research and Development had appeared.

My GPA is lower than a slime’s mana.My name is Atheron il Ataraxia, and I’m the walking disgrace of the Royal Academy of Magic.I’ve been held back twice, my essays are used in class as examples of how not to cast spells, and professors sigh in relief when I don’t blow something up during morning lectures.Truth is? I don’t even like this world.I was summoned. A girl from this world pulled me in like a card from a cursed deck, and now I’m stuck living here. Attending classes, battling evil spirits, and dealing with stuck-up nobles whose names are longer than my backstory.But something’s off. My mana doesn’t behave like theirs. The world listens when I speak. And the whispers I hear at night? They’re getting louder.They say evil spirits wander through Ashgrad under the light of the moon. And I think they’re looking for me.They think I’m a failure.Maybe I am.But if this cursed academy wants to survive the next full moon, they might just have to rely on me — the last-ranked summon with a dangerous secret.

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.
