It's finally starting to look like a real human dwelling.

Now, then...

I don't think I can keep hitting the ignore button on my exhaustion anymore.

Damn it! A human being on his own can barely make it through the day.

Never mind science and progress.

If only I had one more person with a lot of strength...

I've already had my eye on this one.

Right by where I was revived,

I'd seen the uncannily masculine hand of a guy who'd been swept here

from the same direction as me.

Although I've already seen more of this face than I ever wanted to...

It's been 3,700 years, huh?

Hey, big oaf.

Now, then...

Time to get started on the Senku Laboratory.

Yo, big oaf.

What will it take for you to wake up like I did?

What exactly was it that petrified all of humanity 3,700 years ago?

Alien Technological Attack Hypothesis.

Number one...

Dude, earthlings are so lame.

Let's turn them all into stone.

It did work on the swallows.

Petrification Beam!

Lawl, this is exhilarating!

Some Nation's Military Weapon Hypothesis.

Number two...

The petrification device is finally complete!

Oh, crap! It backfired!

New Virus Strain Hypothesis.

Number three...

We're petrification viruses!

We infect only humans and swallows!

Rofl, this is exhilarating!

The only thing that's certain

is that it targeted humans and swallows specifically.

It seems like some kind of insane fantasy, but there must be some underlying rule.

Which means I can fight it.

Figuring out the rules is the basis of science.

I'm standing in the face of an uncharted branch of science.

This is exhilarating.

Now, think.

How did I get out of my petrification?

Was it just simple deterioration?

If it was deterioration, wouldn't the exposed surface have broken down first?

But the stone statues are stone all the way through.

For me,

the surface stayed stone while the rest of me changed back into living cells.

It's the other way around!

The surface was too deteriorated to revert to living cells.

That's why it turned into a stone husk.

The parts of the surface that happened to be less petrified reverted to cells.

That must be why there are pieces missing from the shell.

So I wasn't revived because of deterioration.

There's some special, outside factor.

The fragments closest to my head were on the ground in a pile.

Which means the revival started from my head.

There's something in there.

This smell...

Nitric acid!

The hair on the back of my neck is still petrified.

Let's try it on this stone hair.

Why did only I need nitric acid?

It's not working one millimeter on Taiju or the others.

Why?

What's the difference between me and the rest of them?

Think...

I just need a hypothesis.

Think.

Think...

That's it! I was thinking!

I stayed conscious for all 3,700 years.

The brain burns through 400 calories in a day.

Over 3,700 years, that works out to 2 terajoules.

Where did all that energy come from?

E=mc².

Energy and mass have equivalent exchange.

It's the foundation of science that Old Man Einstein derived.

There's simply no way to make energy from nothing.

There's something in the stone that I was consuming in order to use my brain.

Which means if I can figure out what that was, I can undo the petrification.

Try everything.

Just try it.

I really want to try nital, the industrial etching solution.

Damn it.

Too bad I don't have alcohol.

Laboratory.

Believe.

Try, try, try, try, try, try...

And try some more.

Never forget.

Petrification may be a fantasy,

but the foundations of science are absolute.

I need more manpower.

Take the nitric acid and wake up already, you blockhead!

You're awake, aren't you?

You've been awake for the past 3,700 years!

You're no different from me.

You don't know when to give up!

Senku! I...

Taiju...

- I'll believe in you and wait for as long as it takes. - I'll believe in you and wait for as long as it takes.

I'm hopeless without you!

I'm hopeless without you!

Come back, Taiju!

Come back, Senku!

It stopped raining.

The thunderstorm that was keeping us camouflaged is gone.

Don't raise your voices.

If Tsukasa hears us, we'll be instantly screwed.

You're right!

He's not coming, is he?

I'm impressed you noticed my neck.

I hardly gave you a speck of a hint.

Taiju, Yuzuriha, you both get ten billion points.

Good morning, world.

Good Morning World!

Good Morning World!

How far have I walked?

Only the pain in my feet.

Gives me a sense of the distance.

The hope for a beautiful view at the end of a long night.

Is what keeps me going today.

The mountains of the gods, the palaces of green.

The depths of the caves, the ends of the deep blue sky

I'll go the full distance, there are no limits.

To the ends of the world.

Good morning, world.

Good Morning World!

Good Morning World!

Rid away the impossibility of the dark.

An odyssey turning mythology into the everyday.

In this painstaking journey, turning over every stone.

We'll expand our world.

Two Nations of the Stone World.

Sen...

ku...

Never mind my cervical nerve, you just crushed my entire body!

I'll kill you!

I'm sure you know not to, but don't go thanking me for every little thing.

I won't thank you, either.

Welcome back, Senku-kun.

Don't you think the shape on this hide kind of looks like a rocket?

There are star-looking things, too!

They don't look anything like it.

It looks like a science flag. I bet it'll look good on Senku-kun.

Let's put it on his neck, just in case.

Oh, yeah!

It'll be even better with a splint. See?

Uh, I really don't need this.

I'm all better now.

Professor Senku's self-sacrificing human experiment was a success.

The restorative effects of undoing petrification are too damn high.

The petrification that's given us so much grief is what cured you, too, huh?

You said it when we made soap, too...

But maybe this petrification is the stone of life that replaces doctors for us.

It's Doctor Stone!

Come to think of it, it's weird.

When the petrification is undone, it repairs everything around it, too.

What a considerate scientific phenomenon.

I've been thinking this whole time...

Who petrified humanity?

Who attacked us?

No...

Was it really even an attack?

If it can fix Senku-kun's neck,

maybe if we piece together

the shattered statues and pour revival fluid on them, it'll put people back together.

I tried that right at the beginning.

They just went back to being a shattered corpse.

Why wouldn't it work if it's so regenerative?

Yuzuriha...

Taiju's ten billion percent too crude for this.

You're our ultra-skillful crafts club member.

It'll be a grueling mission.

Can you do it?

That really is really grueling.

But I'll do it!

That was quick.

Craft is all about perseverance!

Are you sharing secrets?

No fair! Let me in on it!

I, um... was saying maybe we should go see Tsukasa-kun.

Oh, yeah?

Tsukasa's place, huh?

What?!

Why?!

He's the dangerous man that killed Senku!

I mean, he's not dead, and he was a good guy, but...

At the very least, he thought he'd killed Senku!

That's exactly what we accomplished in that fight.

Tsukasa thinks I'm in the afterlife now.

Meanwhile, I can always know where Tsukasa is.

We'll have a giant advantage in this battle,

if you two can infiltrate the Tsukasa Empire as spies.

I gave Yuzuriha the details about the mission.

Taiju, you protect Yuzuriha.

Blockheads like you are better off not knowing everything.

All right, I got it.

I'll do it.

Tsukasa intends to use the miracle water,

revival fluid, to amass an army of young people to make a new world ruled by military might.

In order to defeat the Tsukasa Empire

and stop the mass destruction that is the purification of humanity...

We'll have to make a revolutionary army that can combat them using science.

But how are you going to do that on your own?

Yeah.

If Tsukasa has the miracle water, the nitric acid, you can't make gunpowder,

and you can't grow your manpower.

The answer is obvious.

I'm going to find the mystery people who fired the smoke signals

and get them on my side.

The problem is that they might encounter Tsukasa first.

I'll just have to bet on the chance that they haven't.

So, going forward, the two of us will be spies in the Tsukasa Empire.

You'll be finding allies for a scientific revolutionary army.

And we'll each be fighting our own battles.

That's the idea.

I'm getting all teary-eyed thinking about our sad goodbye.

You're both so casual about this.

Guys really are stoic with each other, huh?

Yeah.

Senku is always logical.

We won't be seeing each other for a while.

Not for weeks, months, maybe even...

Senku!

I promise-

Wait, I can't raise my voice.

Hang in there for the short while that I'm gone.

Hey, you've been waiting 3,700 years.

A few more months or years is no big deal.

We're going to build our kingdom of science.

Rear right, 57 meters.

Yes, you, the one who's been following me quietly for the past two minutes.

Who are you?

Blue eyes.

She's young.

Did Taiju and the others just revive her?

Or are there other ways for people to be revived?

Now, that's not nice.

Shouldn't you say "Nice to meet you" first?

Shut your mouth!

Save your introductions for Hell.

Impossible.

She's too young to have such skill.

There's no way the martial arts community wouldn't have heard of her.

Who is she?

I saw everything!

You took a woman hostage,

and then you ruthlessly killed the gentleman who took the hit for her.

I couldn't hear what you were talking about,

but I have no interest in your background.

Repent to the sorcerer gentleman until your soul rots away!

Sorcerer?

You were just bathed in it moments ago, and you've forgotten already?

You were summoning the mountain's wrath with your suspicious black powder!

The mountain's wrath?

A volcanic eruption?

So you may not be one of the revived, but rather, one of their children.

Or...

What generation are you?

She's of a pure, primitive people with no science.

I could rule over them easily.

I could kill them easily.

There's no reason to attack them.

Thus my immediate goal is to return to the cave.

Taiju and Yuzuriha have seen how to make gunpowder.

I need to claim the miracle water before they do.

This is goodbye.

You're... the sorcerer gentleman who protected that woman.

You're alive!

Stop talking.

You can introduce yourself all you want later.

Don't waste your energy.

Can you hold out until evening?

If you're at your limit,

I'll take a gamble and blow it up with the little gunpowder I have left.

But if you can hold on,

it'll take forever, but I'll save you, ten billion percent.

You're the only one who can make the decision!

Decide right now!

Which is it?

Yeah, my organs and bones are all fine.

I can hold on.

I'd say the fallen tree weighs roughly one ton.

To get it to one side would take half of that, 500 kilograms.

Assuming my own weight is just over 60 kilograms,

multiplied by 2 to the 3rd power to get to 500 kilograms...

I can just barely make it with three.

Maybe I don't know what to do.

Hurry up, my mind is on the moon.

The bamboo's barely strong enough.

Flying up to where the wind blew

I'll just have to pack them with dirt.

In my hands awakens.

The passion overflowing.

Just wandering through this world.

Who would have thought that soap would be so useful now?

Your one shining pure.

Could never be pierced with a rusty knife.

It's an all-star team of Great Professor Senku's inventions.

I'm burning like a fire gone wild.

The moment an arrow shot through my heart.

The noise plaguing me was released.

What is this?

Everything was different from that moment on.

This is science.

If I don't try, I'll never know.

It was invented by Old Man Archimedes a few hundred years BC.

Why do flowers bloom?

- It converts the measly strength of a high school kid into Herculean might. - Your voice echoes.

It's called a pulley!

Tell me why?

I just shouted to the sky.

But you are no no no longer here, that's right?

The life we confirmed that day.

You can call it a fleeting dream if you want.

But I'll save you from a wounded today.

Amazing.

No, I'm not talking about that Archi-whoever's wisdom.

I'm talking about your unwavering diligence in forcing yourself through every step

until you solve a problem.

My name is Kohaku.

It seems I've taken quite a liking to you.

Two Nations of the Stone World.
