In MHA with JJK powers.

With a loud sound, the glass of the green container shattered, sending broken pieces of glass flying everywhere.

Stepping on the ground, Shigaraki stood beside Mechamaru.

Slowly turning his head, Shigaraki's red and Mechamaru's green eyes matched.

For a moment they both stared at each other in silence.

"I have a bad feeling about this...", Rabbit Hero Miriko said with a nervous smile, all of her survival instincts screaming loudly at her, telling her to escape.

All Might clenched his fist tightly, his eyes focused on Shigaraki.

All of the heroes around them looked at the two in nervousness.

Just as the atmosphere was getting heavy, Shigaraki suddenly opened his mouth and said slowly.

"Mechamaru?....."

A light passed through Mechamaru's eyes.

"It seems All For One's influence on you is gone."

Extending his hand towards Shigaraki, Mechamaru silently activated idle transfiguration.

"Now you can truly be yourself, Shigaraki."

Shigaraki's gaze landed on Mechamaru's extended hand, but instead of grabbing it, he took a step forward and hugged Mechamaru.

"I am glad you're alive, Best friend."

As if the heroes didn't matter at all, the first thing he did after seeing his friend he thought to be dead, was to hug him.

Mechamaru stood in silence, his extended hand clenched into a fist for a moment before he relaxed and brought it back patting Shigaraki on the back.

"Hah don't tell me you guys are getting sentimental all of a sudden?"

Rabbit Hero said with a sarcastic tongue, suppressing the rising sense of danger.

If it was anywhere else, then she might have gotten away with it.

But what Miriko didn't know, was that someone really didn't like what she just said.

Letting go of Mechamaru, Shigaraki looked at the heroes with dead eyes.

"I believe it is getting a little suffocating in here..."

Turning his head he looked at Mechamaru.

"What do you think friend?"

Looking back at Shigaraki, Mechamaru replied in a calm voice.

"I believe it is, a little suffocating."

The corners of Shigaraki's mouth twisted wide open, forming a crazy smile.

It happened the very next moment.

5 people moved almost at the same time.

All Might, Miriko, Aizawa, Shigaraki and Mechamaru.

Shigaraki was the fastest, he instantly dropped down and touched the ground.

All Might and Miriko moved, rushing towards Shigaraki.

Aizawa's eyes glowed, instantly blocking Shigaraki's quirk.

Looking at the approaching punch from All Might and kick from Mkriko, Shigaraki simply showed a grin.

And in a next moment, the wall of infinity appeared between them, easily blocking both of their attacks.

All Might and Miriko looked at Mechamaru's blue eyes at the same time.

At the same time, Mechamaru raised a pillar of flame in front of him, making Eraser Head unable to suppress his quirk.

Feeling his power returning, Shigaraki activated his power.

"Decay."

From Shigaraki as the center, the terrifying power of death spread out, instantly decaying the ground underneath him, along with the flame wall.

All Might and Miriko's pupils shrank, with quick steps they stepped back and shouted in a hurry.

"Run!"

Eraser Head tried to block Shigaraki's quirk again, but Mechamaru suddenly appeared in front of Shigaraki, unaffected by decay, blocking his vision.

In the next moment, All Might appeared behind him and grabbed Aizawa's neck, bringing him and the other heroes away at a crazy speed.

Mechamaru looked at their running figures in silence.

"Aha....hahahahahaah"

Meanwhile, Shigaraki behind him started laughing like crazy, looking at all the destruction caused by him in happiness.

Suddenly his glowing eyes locked onto Mechamaru, standing completely fine before him.

Opening his mouth, Shigaraki declared in a loud voice.

"Mechamaru! Only you and me! We are the only true ones in this fake world!"

"AHAHAHAHAHA"

The effect of decay became even stronger, destroying everything in its path.

All Might and Mriko hurriedly ran away at top speed, carrying the other members of the team with them.

----

"W-what the hell is happening?"

A hero shouted in disbelief, looking at the curtain of decay rushing towards them.

"N-no---"

His body turned gray in an instant, decaying away.

Horrified looks appeared on the faces of other heroes, turning around they quickly started running away to save their lives.

Unfortunately, the speed of decay was faster than many of their running speed.

In no time another hero fell prey to the approaching destruction.

Just when it looked like many of them were going to die.

A green light surrounded the heroes and quickly pulled them away, saving their lives at the end moment.

----

At the villain's Headquarters.

The effect of Twice's big move was visible to all.

Looking at the massive amount of black figures rushing forward madly, the heroes were caught off guard.

"G-get away!"

Hero Mount Lady shouted in a loud voice and smashed her leg down at the Twice clones, destroying them.

Hero Edgeshot kept moving like crazy, killing every clone that came in his path.

Unfortunately, there were just too many of them.

But it wasn't like the heroes were helpless.

"Everyone get back and leave this to me!"

Hero Midnight shouted and made a gap appear on her hero dress, pink fog spread out from her, enveloping the upcoming Twice clones.

As soon as the clones inhaled the pink fog, they fell down, falling asleep.

Suddenly the advance was halted, giving the heroes room to breathe.

Spreading her quirk at full strength, Hero Midnight used the closed building to her advantage, the pink fog spread quickly, reaching the upper floors.

Blocking her nose, Hero Mount Lady placed a hand before Midnight, understanding her intention, Midnight quickly jumped on her hand.

Mount Lady held her breath and hurriedly sent Midnight towards the source of Twice's clone.

And it was effective.

The original Twice who was hiding among his clones, under Midnight's quirk fell unconscious, ending the sad man's parade.

The hero's raid was a success.

Just when everyone was heaving a sigh of relief.

Black water suddenly rushed out of every captured villain's mouth at the same time.

"What?"

Under the heroes's surprised gazes, all the villains whom they just captured, suddenly vanished away, leaving nothing behind.

"What was that?!"

"A new quirk? Is it another villain?!"

The heroes were agitated, it felt as if all of their hard work was suddenly destroyed in the blink of an eye.

Hero Edgeshot looked at the scene in confusion.

Just then.

A single command rang out through every hero's communicator.

"Everyone gathers at the Jaku General Hospital Now!"

----

Mechamaru looked at the decayed land all around him, in the blink of an eye, almost thirty percent of Jaku City was gone, turned to nothingness.

*Urggh*

Listening to the coughing sounds, Mechamaru turned his head and saw all the members of the League Of Villains sprawled on the ground behind him.

They were brought here by Shigaraki who has perfectly inherited all of All For One's quirks.

Mechamaru's gaze landed on the unconscious Twice and Toga.

It seems the effect of Midnight's quirk on them was wearing off, or maybe Shigarki did something as they quickly woke up.

"S-shigaraki!? M-Mecha-chan!"

Toga looked at the smiling Shigaraki in confusion, then she saw the familiar metal figure, her eyes instantly glowed as she hurried towards them at a quick speed.

"Mecahamru! Shigaraki you're back!"

Twice who just woke up also shouted in a loud voice and ran towards them with tears in his eyes.

All the other new members of the league were also excited as if they just saw their backbone.

They raised their hands and shouted in joy.

"The heroes will lose today!"

"It's the beginning of a new era!"

Dabi, Magne, Mr. Compass, and Re-Destro made their way out of the crowd and stood before Mechamaru and Shigaraki.

The League Of Villains has assembled.

It was a sight to behold.

And as if on cue, the sound of a helicopter rang out from the sky, Shigaraki smiled and turned his head.

On the very edge of the decayed ground, he saw it.

The heroes gather together.

Forming a crowd similar to their own.

And the one standing at the front.

Was none other than All Might who just ran away like a scared cat just moments ago.

On one side stood the villains.

On the other side stood the Heroes.

They both stared at each other, in silence and nervousness.

The media helicopter in the sky quickly captured everything, streaming on live television.

Shigaraki's eyes narrowed, seeing the scene a brilliant idea came to his mind.

Turning to Mechamaru he said with a smile on his face.

"My friend I remember you told me you're goal before....to be feared by everyone."

His gaze focused on the heroes in the distance.

"Then go ahead and make the first move! Driving fear into the hearts of everyone!"

Shigaraki's eyes started glowing like crazy.

Every member of the league looked at Mechamaru.

Mechamaru glanced at them, then turned to Shigaraki and nodded.

"Thank you...friend."

Shigaraki's smile instantly widened.

Then under their hot gazes, Mechamaru took a step forward, Walking calmly towards the heroes.

His figure was instantly noticed by the other side.

All Might clenched his fist, but just as he was thinking about something, he saw a familiar figure walking out from the heroes's side.

"Kurokai-shounen?....."

All Might called out his name in confusion.

But Kurokai ignored him and continued moving forward.

All Might was just about to rush to Kurokai when Aizawa suddenly raised his hand and stopped him.

All Might and Aizawa's gaze collided.

"I believe my student must have a plan."

Seeing the certainty in Aizawa's eyes, All Might couldn't help but stop, remembering Kurokai's power a light passed through his eyes as he looked at Kurokai's back with a hopeful look.

Hero Miriko glanced at Aizawa, then focused her gaze on Kurokai.

Looking at All Might's reaction, other heroes who were about to rush forward stopped and simply looked at Kurokai in silence, ready to make their move at a moment's notice.

The students of class 1-a also arrived at the scene, looking at the standoff between the two sides, they became nervous, and seeing Kurokai and Mechamaru walking towards each other made them hold their breath, unable to breathe.

"What are you thinking? Kurokai kun?....."

Momo said in a confused voice, not understanding his motive.

Midoriya beside her tightly clenched his fist, his eyes looking sharp.

Asui placed a hand on her chest, feeling her anxiety increasing.

----

The pain was increasing.

This is it.

Kurokai thought in his mind.

A final act.

A final fight between Kurokai and Mechamaru that will end in the villain's defeat.

Kurokai and Mechamaru walked towards each other with unhurried steps.

Mechamaru will die, the villains will be captured, I will get Toga and the others out of prison later, then use idle transfiguration to change their appearances, and help them live a normal life.....

It was a good plan, at least he thought so.

A happy ending for all.

Kurokai's brows furrowed.

There it was again, that familiar pain.

It felt annoying, he wanted to use his fist and slammed it against his head.

But right now he had more important things to do.

Kurokai and Mevhamaru stopped at the same time.

Looking at each other's eyes.

With merely an arm's distance between them.

Everyone held their breaths together, looking silently at the scene.

Ah, I remember now.....

Mechamaru and Kurokai raised their arms at the same time.

The pain.....

Sending a punch straight towards each other's face.

But then.

Something unexpected happened.

The world seems to slow down.

Kurokai's mind became blank, looking silently at the approaching metal fist.

He suddenly remembered something he has forgotten.

The pain.....it started when I received Jogo's powers.....

And it was at that moment.

A screen he was all too familiar with appeared before his eyes.

[Congratulations on collecting 1000 faith points, receiving Sukuna's cursed Technique "Shrine".]

With but a single message.

That shifted the boundaries of good and evil within mind.

Under the influence of new memories and cursed energy.

Changing the future of the world.

Towards the dark side.

----

The pain increased again.

But instead of getting angry, Kurokai smiled.

A smile that shocked everyone.

A smile he gave while wrapping his arm around Mechamaru's neck, like old buddies.

Looking at the stunned onlookers, both Mechamaru and Kurokai said at the same time.

"We are one."

Bringing forth an unknown future.
