[Crossover] The Happy Life of an Unconventional Support

Aotu World x Crossover

Jujutsu Kaisen: included

Bungo Stray Dogs: included

Detective Conan: included

Others undecided: going around saving characters from their deaths

The protagonist is not a character from the original Aotu World series.

The protagonist is intelligent, capable, and ambitious, rises quickly, and gets along with both the red and black sides. They are connected to the world's consciousness.

The protagonist is the world's human pillar.

No angst; the whole story is lighthearted, happily saving people from their fates. An ultra-overpowered, ultra-lovable protagonist. There will be a little crossover with the children of light.

I won't abandon this story!!!

Rescue.jpg

Yan Yu was about to lose it. One moment she had just died, and the next she had arrived in a strange place. Before she could even figure out what kind of world this was, she was forced to fight.

Yan Yu, who believed in peace, tried to reason with the other person, but they rattled off a whole bunch of things she couldn't understand.

Oh, they can't understand each other's language...

Then why bother reasoning? I'll make them submit through "virtue"!!!

Yan Yu grabbed a staff taller than herself and swung it at the other person.

Hey! You late-stage chuunibyou! Yes, you! The one called Ryomen Sukuna! You were the one who provoked me just now, right? Ya xi la you!

A moment later

Yan Yu: "..."

Why do you have to be so strong!?

Ryomen Sukuna: "..."

Why won't you die already!?

The two became friends in name and frenemies in truth, and spent every day looking for a chance to fight.

Uraume: I've been through too much.

After communicating with the world's consciousness, Yan Yu was forcibly sent to the present day. When she learned that Gin, who played dirty, had ambushed a certain rolling washing machine from behind...

Yan Yu: ...Master! I understand now!

Yan Yu looked at the support-king's scepter [staff] in her hand and grinned, making a sound that meant someone was about to suffer.

When the world's consciousness suddenly teleported Yan Yu, she instinctively smacked the person who appeared with her staff. The sound of her wild laughter stopped at once. Yan Yu found herself facing a spiky-haired boy staring at her in confusion... and a pink-haired boy she'd just knocked unconscious with one blow.

Yan Yu: "..."

I'm sorry!!!

After learning who the boys were some time later, Yan Yu fell silent, then hurried to the youth center. There, she locked eyes with her old friend Ryomen Sukuna. Yan Yu fell silent for a moment, then approached him with a deeply affectionate look. As he stared at her as if she were an idiot, Yan Yu smacked him over the head again.

After learning that Yan Yu was the one who had hit him, Sukuna said he felt thoroughly insulted and shouted from inside the body of a certain little tiger.

Yan Yu, you damn... (OOC)

Furious, Yan Yu popped her head out again.

"Thwack!"

Yan Yu: The world is quiet now.

Looks like he got sent back again.

A certain tiger boy: My head really hurts.

"How... old are you?"

As former cult leader Suguru Geto looked on in confusion, Yan Yu answered with an air of pride.

"Written as 15, pronounced as 157!"

Suguru Geto: "...?"

Nonhuman, of the royal elf bloodline, Yan, a long-lived species, Yu: "Ehehe!"

Suguru Geto: "..."

"Chuuya~ I'm just support~" Yan Yu put on a frail act and gently waved away an enemy who had been knocked to the ground.

Enemy: Dead.

Yan Yu: "..."

Nakahara Chuuya: "...You call that frail?"

Oh no! I used too much force!

...Check out the neighboring story:

[Demon Slayer: I Really Love the Sun!]

What does it mean to be human? What are the seven emotions and six desires? What are feelings? What does it mean to [live like a human]? What are sadness, joy, pain, and being moved?

"I want to live like a human, beneath the sunlight!"

The girl, born a demon, wished for this.

"Doesn't it hurt?" asked the black-haired girl wearing a fox mask tilted to one side. "Touching the sunlight over and over?"

The demon girl froze for a moment, then answered blankly,

"It hurts, but when I pull my hand back, it's so, so warm..." Longing shone in the demon girl's eyes.

"Makomo, this way I won't feel cold anymore, right? As far as body temperature goes!" The demon girl excitedly took the other's hand.

The other girl simply smiled and stroked the demon girl's soft pink-to-gold gradient hair without saying anything.

"Rui?"

"Rui?!"

"Rui???!!"

"You don't remember? I exist! How could you! How could you! How could you!!!"

"What are you even talking about!" Lower Five said, though inwardly he instinctively avoided saying anything even harsher.

"...He's so mean. My best friend got stolen from me! Stolen!" Hanyu Akina said, her eyes filling with tears at some point.

"Hiss!"

He got bitten.

She was turned into someone else's demon...

"I like you, you who are like sunshine (●, ●)"

CP: Lower Five, Rui

Coming soon:

[Demon Slayer: What Does It Have to Do with Me, Kibutsuji Tsukihiko, If You Want to Destroy Kibutsuji Muzan?]

Blurb:

Kibutsuji Tsukihiko, one of the three great figures in the kendo club, calmly opens the dorm bathroom door to wash his face, then... finds himself staring at more than a dozen people in a completely transformed bathroom.

Is this... a paranormal incident? Has the bathroom come alive? A magic door? Doraemon Yoriichi?

Kibutsuji Tsukihiko is so startled he immediately shuts the door.

"Hey, Kokushibo, the dorm bathroom has come alive..."

Kokushibo, whose name is Michikatsu Tsugikuni, glances up from his book at Kibutsuji Tsukihiko. After a long moment, he rolls his eyes and says, "What weird meme is this now? If the bathroom's broken, you should ask the all-purpose Yoriichi."

"He's not in the dorm!! And I don't want to get hit!" Kibutsuji Tsukihiko grips his wooden sword, takes a deep breath, and braces himself. He knows perfectly well that what he just saw was no illusion!

"How many times have you been hit already, you trash boss?" Michikatsu Tsugikuni says without reacting.

Kibutsuji Tsukihiko: "...Fine."

He opens the door again.

Oh, familiar people and things...

A boy charging at him, shouting "Kibutsuji Muzan!"

Kibutsuji Tsukihiko: "...?"

How do you know that I'm known as Kibutsuji Muzan?

Kibutsuji Tsukihiko blocks the blade, his pupils trembling in shock.

When the other boy's first strike fails, he follows up with a headbutt. Beautiful! A direct hit! Critical strike!

Kibutsuji Tsukihiko: Thanks for the medicine, my head's ringing...

Mumbling, he collapses limply to the ground.

"Yoriichi... someone played dirty... He ambushed me..."

? School AU

? Kibutsuji Muzan and the Tsugikuni brothers are in the same club and share a dorm room

? The trio are extremely close; Rui calls them the Three Weirdos

? The three great figures of the kendo club

? Muzan's redemption: currently a chuuni goofball Muzan [very OOC]

? Muzan uses Sun Breathing in this setting

This comedy is the most poisonous of all! No deaths at school; the original cast can be saved! Lots of plot holes, so please don't complain if you dislike them.

Theme: The best support is to smash the enemy's head in!
