Original subtitles

Shishio Tsukasa is a good guy...

and a murderer.

If we make weapons of science before he takes notice, we win.

If he finds out first, we lose.

That's the kind of race this is.

Guns.

We're making gunpowder.

This is exhilarating.

Hakone.

If they make gunpowder, I don't stand a chance.

I'm going to stop them before Senku can make it.

Yuzuriha...

I should tell you about what happened while you were petrified.

3,700 years ago, when I called you to the camphor tree...

Hear me out, Yuzuriha.

For the past five years, I've...

What were you about to say that day?

Yuzuriha, for the whole time I was petrified,

I thought about finishing what I was saying.

For hundreds of years, thousands of years...

But here, in this stone world,

with nowhere to run, I wouldn't feel right as a man telling you.

Sorry! I'm sure you have no idea what I'm talking about...

No, I do.

We have to bring back civilization.

Once we save humanity,

will you let me finish what I was saying 3,700 years ago, Yuzuriha?

Okay, got it.

We'll bring the world back.

I'm sure of it.

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.

Fire the Smoke Signal.

We have the three materials we need to make gunpowder.

We have them already?

All we need to do now is mix it.

It's time for our happy gunpowder cooking session!

Kitchen.

Ingredient number one for gunpowder...

Sulfur, which we can get plenty of at this hot spring.

Number two...

Charcoal.

We can get all we need by burning wood.

And number three,

the last, but most difficult: Potassium nitrate.

It'll take a hell of a long time to make this stuff, so...

Kukuku!

I've already made some to save us time!

I feel like I've heard the word "nitrate" somewhere...

Nitric acid!

Miracle water!

You got it from that cave?

You're right for once, simpleton.

Ten billion points for you.

Potassium nitrate, sulfur, and charcoal all go in the mix,

and a pinch of sugar as a secret ingredient gives it a little more oomph.

This is glucose that I made from grapes.

Hey! My name is Mecha-Senku!

That recipe I just gave you is legit.

It can result in a real bomb.

So don't even think about trying it!

Finally, pound it until it's packed solid.

Pound it, huh?!

Leave the heavy lifting to me!

Are you sure that's a good idea?

You might be strong enough to make it spark and go boom!

Like flint!

Nah, you won't get any sparks by hitting stone with stone.

Really?

Oh, you're right.

Flint is more than just stone.

It needs to have metal in it to make sparks.

Hot springs,

Hot Springs

volcanoes,

Volcanoes.

Iron Pyrite

iron pyrite...

Iron Pyrite.

Iron pyrite?!

P I u s - Taiju's OP Strength.

Wai-

No problem!

Our gunpowder cooking was a huge success!

I had no idea gunpowder was so powerful.

Yeah.

There've been plenty of accidents where students

were experimenting with it and got their limbs blown off.

It can easily be lethal.

We're going to attack Tsukasa-kun with this?

No, we're going to make a deal.

Tsukasa isn't a mindless killer.

Taiju, remember what he said when you went at him?

Let me get this straight.

You'll let me keep hitting you and never fight back,

therefore, don't destroy the statues.

Is that right?

That's right!

I don't understand.

There's no deal being made here.

In other words, in the right circumstances, we can negotiate with him.

As long as we have a gunpowder weapon, we have leverage.

But if negotiations with Tsukasa fall through,

then we'll have to...

If Senku has already made gunpowder,

I'll have to...

kill him.

All right, it's gotten a lot weaker.

If Tsukasa's after us, there's a ten billion percent chance he'll find us.

Senku-kun, Taiju-kun...

A smoke signal...

Tsukasa-kun?!

No, that's in the opposite direction.

Besides, Tsukasa has no reason to reveal his location.

What is it, then?

A forest fire?

It's too well-timed to be a coincidence.

It was clearly raised in response to our smoke.

You mean...

Yeah.

This is exhilarating.

There's someone else in this stone world.

More people?

We have to finish putting out the fire.

Oh, that's right.

No, hang on.

As far as they know, that explosion could have been from a volcano.

We need to signal them even more before they leave.

I see!

But if Tsukasa-kun is after us...

We'll be doing him the courtesy of letting him know where we are.

The least logical part of me, my gut, is talking to me.

If we start a fire now...

Which do I choose? Safety?

The future?

What do we do, Senku?

Put it out?

Or light it?

Light it!

Fire the smoke signal!

We're running out of gunpowder.

Throw in anything that'll burn!

Hang on! I'll go get some wood!

It's a double-edged smoke signal.

We're letting everyone in the vicinity know where we are.

If Tsukasa knows about our plan to make gunpowder...

Senku is trying to make gunpowder.

The shells told me as much.

There are four insanely useful ways to use it.

Didn't I say three?

Senku hid one because he thought I could be a threat.

Which means...

The fourth important use for sea shells is

weapons of science.

It's easy to imagine.

For example,

mass production of potassium nitrate, which is used in gunpowder.

That's it.

Senku was already thinking ahead

to a future in which he'd use gunpowder to fight me.

"If weapons of science enter the scene,

I won't be the most powerful anymore."

You look like you're about to throw a tantrum, Tsukasa.

You could put it that way.

If you make weapons of science and revive the older generations,

they'll begin fighting over established interests,

and we'll be right back in a tainted world.

I don't mind getting my hands dirty in order to stop that.

So now you have to kill Science Man Senku here, huh?

America would be moved to tears by your merciful death sentence.

Yeah. But first,

would you mind giving me the recipe for the petrification revival fluid?

Sorry, but I'm not as merciful as you are.

I can only look at things logically.

I don't care one millimeter what you do with that woman.

There are plenty of females around-

Don't try to negotiate, Senku.

You never buried Yuzuriha.

Your best move would have been to bury Yuzuriha somewhere

far away while she was petrified.

That way, she'd never be taken hostage.

There's no way you couldn't have thought of something that even I did.

But you didn't do it.

Was it for Taiju? Or for Yuzuriha?

No, it was for both of them.

You call yourself logical, but you have friends that are precious to you.

I have plenty of admirers, but I have no one I'd call precious.

That's why I win, Senku.

I actually appreciate that.

Washing my hair is a pain in this world.

Don't tell him, Senku-kun.

So long as he doesn't have the recipe for the revival fluid,

Tsukasa-kun can't kill you.

I don't mind.

But you have to survive so that you can secure everyone's future.

The revival fluid is a compound of nitric acid and alcohol.

Filter the miracle water from the cave,

and mix it with alcohol that's been distilled

up to as close to 96% as you can get it.

The ratio is 30% miracle water to 70% alcohol.

If you're off by so much as a few percent, the reaction won't happen,

so fine-tune it using a petrified swallow feather.

Thank you, Senku.

I no longer have a reason to let you live.

This should be enough.

Three smoke signals!

They must be responding to the three shots we fired with the gunpowder!

There's no mistake!

There are people!

Senku!

Yuzuriha!

Three.

If I let you live,

you would let civilization develop.

Will you promise that you won't do that?

What the hell are you talking about?

Why would I ever keep a promise like-

No, you would never lie.

Not to science.

Will you promise here and now, for all eternity, that you'll abandon science?

If you do, I won't have to kill you, Senku.

All right, next is Senku-kun.

I'm going to space.

An astronaut!

What I want to become.

That's a great dream.

Well, when you grow up...

No, I'm going immediately.

Then again, I'm just a kid who doesn't know the first thing about science.

I'm going to study

every last thing.

I'm going to try everything.

I can't help you.

But, Senku, if you're serious,

you can accomplish anything through diligent application of science.

Used Cars

I'm sure Santa Claus will give you the tools you need.

You can burn things with the point of light from a magnifying glass.

What an adorable experiment.

Sand iron and aluminum foil are awesome!

The frying pan is melting from the thermite reaction.

Adorable...?

The liquid oxygen for the injector boils off ten billion percent at a normal temperature,

and it freezes when it's too cold.

I'll have to keep trying with ethanol for a while until I switch to kerosene.

What's that?

It's an ablator.

The chamber will burn out if I don't use it.

Hello.

I need a Raspberry Pi, a transmitter module, and this thing called a "gyro."

We'll use a good old Yagi antenna for the receiver.

It's what they'd use for TVs.

Senku!

You said you'd try it with a light payload, right?

I had Ogawa Yuzuriha-san of the crafts club make us three passengers.

It's seriously embarrassing, having a doll of myself.

What are you even using these for?

It blew up at a really high altitude.

Failed again?!

Not entirely.

I'm going to space.

I'm going immediately.

You can accomplish anything through diligent application of science.

Senku, I'd rather not kill you if I can help it.

I'll ask you again.

Will you promise me, here and now, that you'll abandon science?

I can't do that.

I thought that would be your answer.

What are you babbling about?

You were going to kill me at some point, no matter how I'd answered.

To be on the safe side.

Perhaps.

Do it in one blow.

Making me bleed out forever wouldn't be logical for either of us.

Don't worry.

I'll bust your cervical nerve in a single blow.

You'll be knocked unconscious instantly, and then you'll die.

I won't make you suffer.

I promise not to miss.

Taiju-kun...

Yuzuriha...

Senku!

Senku, if we'd met 3,700 years ago...

If we'd met before this planet became a stone world...

You may have been my first friend.

Maybe.

Senku!

Maybe I don't know what to do.

Hurry up, my mind is on the moon.

Flying up to where the wind blew.

In my hands awakens.

The passion overflowing.

Just wandering through this world.

Your one shining pure.

Could never be pierced with a rusty knife

I'm burning like a fire gone wild.

The moment an arrow shot through my heart.

The noise plaguing me was released.

Everything was different from that moment on.

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

Why do flowers bloom?

Your voice echoes.

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.
