[Western Crossover] I Joke Around with the World

(To be started after Cyberpunk Corpse Doctor is finished)

"This world is one big joke."

Ever since she was born, a black light has surrounded her.

After surviving her father's failed sacrifice, she could see those black things. They surrounded her, and at first, they seemed to be misfortune, the kind no one else could see.

But later, she saw them clearly. They had never been misfortune, just a bunch of children who didn't know any better.

She, too, went from being a child to becoming the mother of monsters, as defined by the rules.

Then she went from being the mother of monsters to an agent who traveled through several worlds, a guardian of the universe.

But the joke wasn't over. Her brother, who had been asleep for many years, once again teetered on the brink of death just as he was about to awaken. There was only one way to save him: save the monsters of this world, and save the world itself.

She couldn't let the monsters disappear. They were born because of humanity, inhabitants of Earth since time immemorial, and her children. She was the mother of all monsters.

But she was human, too, and a guardian. The retired savior was back in action.

She planned to play a joke on the world, and on the guardians.

The ability she was given in her own world from the moment she was born had also been strengthened after she arrived here.

In a world that was similar, yet different, she was the "Fool" and the mother of monsters.

How do you create an organization from scratch that has existed since time immemorial, without having to use your brain?

The answer is that you need an ability. It can split off part of your personality, spread it automatically, then personify it, creating a secret identity that belongs entirely to you and has a certain degree of autonomy.

They are part of you, and you can watch everything they do in real time, but they have to learn their skills from scratch.

She had spent nearly twenty years preparing for this.

The Fool is an organization that has existed since ancient times, and no one knows where they came from or what their purpose is.

But wherever there are monsters, they are there.

Read these content warnings:

1. The secret identities have a certain degree of self-awareness, which develops from nothing. They can basically be understood as similar to Mori Ougai's ability in Bungo Stray Dogs, with some misunderstandings. They are not secret identities in the traditional sense. See the author's note in Chapter One for a detailed explanation of the ability.

2. There are real deaths. Personally, I think they feel more like real deaths. No bashing of characters from the original works, and the protagonist is not related to any superheroes.

3. Aoi's past includes some mental health issues, but she has been cured by the main story's timeline. She is very maternal, and in a sense older than some superheroes (she is 150 when she appears).

4. The male lead is Kusuo Saiki. He doesn't appear much in the main story (he mostly exists in text messages, and they are already together from the start).

5. Aoi's starting world is Earth. Her first transmigration is to a crossover world, and the second is here. The story does not cover the first transmigration, and about fifty years have passed since she left the world of her first transmigration.

6. No bashing of any characters from the original works. The Joker must die.

7. More to be added if I think of anything.
