All For One tries to feel whoever says as he knows there are thermal cameras inside this cell, capturing everything the invisible.
Yet, the person talking to him doesn't trigger an alarm while being here.
"So, what do you think?" The teen voice appears again, still with a joyful tune -"Wanna have a deal? And you can talk. All those ancient technologies have been disabled."
That impresses All For One since Tarturus's security is one of the most advanced prisons in the world.
"Hahaha." AFO giggles a bit -"I'm sure that you know my thought, judging by the fact that you single-handedly breach the Tartarus with ease."
"And you may also know my thought on dealing with a suspicious person." AFO finishes as the person suddenly cracks laughing up.
"HAHAhahaha. You're just as I learned about." The person says -"And you sure don't want to deal with me, do you?"
"Yeah." AFO agrees -"And I don't even know if you're just a phantom or a hallucination of my imagination."
Suddenly, a light flashes him so bright that he's unable to...see?
He was blind but now? AFO's surprised to 'see' the fortified steel walls and the cameras. Everything around him. Yet, he's still tied into the chair.
But more surprisingly, standing before him is a black-haired teenager as tall as him. One eye is pure crimson with a yellow triangle inside the pupil. Whereas blue static is the only thing visible in the other, with no pupil nor iris. And he wears a a brown khaki trench coat with brownish-gray shirt inside.
.
"Now that you 'see' me now, shall we have a deal? You will have a higher chance to win One For All."
AFO shows a slight surprise yet quickly turns calm.
"Hahaha. I don't need an ally to win that remnant. I may have planned this long before you were born." He says with pride yet calmness.
"And what if I tell you that your plan will be ruined by a boy." The teen says with a joking tone -"And that your plan would never succeed without my help."
That frustrates AFO a bit.
"(Giggle) Oh, I think you shouldn't say that to me. Though you managed to get here alone, you act so naively for the thing you used for that." And he underestimates the boy, who looks like he's trying to hold his laugh.
"OH, BOY! Guess I need to show you my power." The teen says with the same tone and points his hand at AFO.
.
*STATIC*
Suddenly, the next moment AFO notices, he's now in a vast empty space.
The scene around him is very similar to Kamino, where he fought All Might for, maybe, the last time.
From the debris of the building to the remnant of the ground, all gets messed up like toys. And the atmosphere is so dim and unpleasing for any 'normal' person.
And then he looks at where All Might stood against him in his pathetic appearance. But instead, he sees an enormous skyscraper with a light flicking on the top, overshadowing him. Dark cloud swirls around the top like a storm.
.
Suddenly, a yellow light sparks in the dark, and as it seems to come closer, AFO realizes the previous teen sitting and smirking on the debris.
"How is it? I replicate this from your memories." The teen says friendlily after he jumps down the debris and approaches AFO -"And also makes you back to your golden age." and puts his hand on AFO's chest.
AFO looks at the boy with curiosity of how powerful he is to create such place.
"I think that it'd be dramatic and funny that I defeat you when you are in your strongest." The teen says with slight excitement -"And our battle shall start after you act first." and underestimate AFO.
.
Then, out of nowhere, two katanas appear from his hands, carved with an eye in a triangle. Static fills the edge like the katanas are covered with bright blue glitching fire.
And as he points the swords at AFO, space between them suddenly expands, and the buildings and scenery around them disintegrates into dust, swirling around them like a colosseum.
"No escape, and no interruption."
Then, a chair appears behind the teen from thin air.
"Hope you win me, which you won't!" The teen says conceitedly as he comfortably sits down on the chair -"And take your time. I won't mind."
And AFO is more frustrated by the teen's contemptuous attitude. He prepares all the empowered quirks that he's got.
Strength. Repel. More strength. More others. (Just imagine every strengthening quirks)
And his hands inflate and looks rough like rocks and metal. And more metal-like spikes grow on his fists like knuckles.
"Here it is!" *BOOM*
AFO says as a burst makes him rush to the teen with murderous intention.
*CLARK!*
A collision between AFO's hands and the teen's katanas signals the clash of the strongest.
.
However, contrasting to AFO's thought, the teen just...sits there with one katana so tiny compared to the gigantic fists and smirks with disappointment.
"That's all you got?"
"DISAPPOINTMENT!" The teen shouts as he slashes the sword down drastically, creating a pulse so powerful that it pushes back AFO, who blocks by the giant arms, quite a distance, making him surprised by the teen's quirk.
.
And as AFO opens his arms to observe, the teen starts walking to him slowly but menacingly, with the hands weighing both glitching katanas. And on his face, a slight sinister smile grows.
AFO then switches to ranged attacks by using various quirks.
.
Rocks fly towards the teen. Cut to half like knife cutting butter.
Blaze bursts fiercely. Put off real quick like in vacuum.
Hyper-jet water pierces through air. Quickly wears off before reaching its goal.
.
The more AFO uses all his quirks against the teen, the more he realizes how dominant and powerful the teen is.
"How are you this powerful?" AFO shouts to the teen while bursting some jet air -"WHAT are your quirks?" to which he replies.
"(Giggle) It's so naive of you thinking that my 'Signal' is a quirk." The teen says while walking relaxingly and doesn't even care about the things that can kill a person effortlessly.
"What do you mean?" AFO shows a slight panic in his eyes.
"Your 'quirks'. It requires physics and use. But mine?" The teen answers -"(Smirk) It defines physics!" and fuses his katanas into one static-filled great sword, striking down and cutting AFO's arm, not even giving him a chance to react.
Though he doesn't feel any pain losing an arm, the strike also negates everything that AFO keeps creating to fight against him.
"The fight is won before it's begun." The teen looks cold and points the great sword at the weakened AFO, who knees on the ground and holds his bleeding detached arm. Seemingly, he accepts his defeat and demise.
The teen glares at him so intense that anyone with a normal mind will shiver before him.
.
"Kidding!" The teen turns his expression 180* and smiles at AFO like a friend, making AFO look at him confusedly -"And now that you know I'm stronger than you..."
And two chairs, like the previous one, along with a table appear near AFO, and the teen sits down one of those.
"Come and take a seat." The teen says -"Oh! And your arm is back!"
AFO shows a slight confusion and then be shocked as he looks at his previously missing arm. Now, it's back. And not only that, every wound on his body are also recovered.
"How strong is he?"
"Have a drink!" Multiple kinds of drink appears from thin air -"Though this won't have any effect, I can replicate some."
AFO doesn't drink any, but just ask after sitting down.
"What is your purpose of this?"
"Oh! So, you want to move to the main point right away? Nice!"
"But I have to say this: You 'may' win the century war against One For All unless a duo messes it up even more." The teen says as he creates a holo-screen out of thin air.
A boy with a paper bag and a girl with a yellow raincoat talking happily with each other.
"Huh! Why would I lose by those?" AFO says with slight pride.
"And that's the reason you'll lose." The teen says as he makes the screen gone -"In every scenario I see, you always underestimate the strength of current heroes' generations and their 'friendship' power."
"(Laugh) You also believe in that?" AFO says.
"I know, right?" The teen says and smiles with joy -"And now, do you make an alliance? As there will be chaos if we do so." And raise out his hands, covered in gloves.
AFO doesn't agree that quick. He asks for more information.
"Can I ask four questions?"
"Ok. I'm fine with that." The teen retreats his hand.
.
"What's your purpose of alliancing with me? I can see that you can overrun the government with ease."
"Hahahaha. That's a good joke. But yes! Though I can easily take over Japan and the local easily, that won't let my plan go well and easily."
"Interesting..." AFO thinks.
.
"Second, what is your deal with those two UA students who can ruin my plan?"
"No! Even without those two, you will fail no matter what, but you will fail less shameful without them."
AFO looks at the boy thoughtfully -"So, he can see the future? Or a possibility?"
.
"Third, When will you betray me?" That question makes the teen slightly surprised but then he smirks minorly. His triangle pupil slightly glows and grows slightly.
"Oh! Didn't expect you to ask so drastically." The teen answers -"But you know? The alliance between the villains never end well. And so is ours. But here's a good question."
"Who will strike first?"
Now, AFO is very interested in the boy's intention and plan.
The two smiles at each other like they understand the other very well. Like two pals agreeing on something without talking.
"Now, I can say we can make an alliance." AFO smirks as he actively raises his hand to shake.
Excitement can be seen on the teen's calm face.
"Now, we're talking." And he shakes AFO's hand.
.
Suddenly, AFO feels an ominous chill coming from the teen. And a giant eye in the triangle stares at him from the top of the skyscraper, shining like a spotlight.
And the teen also smiles creepily as AFO feels his lungs being pressed by the stress.
.
Then, it also drastically disappears, like when it suddenly pops up.
"Now, you can return to the jail and wait for your boy, Shigaraki, to come." The teen says as a blue static portal opens behind him.
"Now, Can I ask the last question?" AFO asks as without mentioning the drastic experience.
.
"What's your name?"
.
"Monaural." The teen answers with a slight satisfied smile -"Monaural Mozart."
.
.
Then, AFO sees himself in jail, blind and trapped.
"I will look forward to what you're intending, Monaural."
A smile grows on his face as usual, but this time isn't for his master plan, but for the excitement of the alliance that he made.
