Dr. STONE (Dr.STONE)

W-- wait. For real?

We need your brainpower, Sai.

We have to learn everything about rockets.

And that means we'll need all the help we can get with the ridiculously hard math it's gonna take.

Will you teach us math, please, Sai?

Teach you math, huh?

I mean, I've taught before.

It was kind of a side gig to stay fed while I was busy coding.

But it's like learning a whole new language.

And you'll be starting at square one.

You'll have to take this seriously.

Oh, yeah.

We're serious as we can be.

The stakes couldn't be higher, and there's not much time.

We gotta build our return-trip rocket before the one-way rocket's ready

because there's no way we can have a happy ending

without everyone here with us to celebrate our victory over Why-man!

God damn it!

I went all around the world so I wouldn't have to build that freaking computer.

But this has gotta suck at least 10 times more!

So if I understand the situation correctly, we're using these red rocks here

to build this new rocket vehicle thingy?

Yeah, we'll process the hell out of them

by following this road map here.

And at the end of our journey,

we'll have the raw materials ready for making our rocket.

It'll be super complicated and challenging.

And that's the stuff I live for.

Oh, so this must be why we grabbed up all those firefly rocks in Spain.

We're in for more ega-may time-consuming work, huh?

But let me ask you, what's that about?

It says an absolute crap ton of stupid, powerful electricity.

Oh, yeah.

There's a reason some people like to call aluminum canned electricity

because making it takes an absolute crap ton of power.

Take the bills they rang up making the aluminum for the Apollo rocket.

It cost them over 3 billion yen in power alone.

Not wrong.

You would need a limitless supply.

And if we want that much power, the only way we could generate such an immense amount--

Is using a hydroelectric dam.

That's why we're going to take all these red rocks with us,

shipping them out to a country that's perfect for hydropower.

Water power, right?

So what would be the best country for building our dam?

It's a place that we're all familiar with,

chock full of peaks and valleys and loaded up with rivers.

And the funny thing is,

we've got materials in HQ already set up.

It's been a while since we last set foot there, but it still feels like home.

Japan.

All these new cities will be coming together.

We traveled all over the globe to gather the best materials out there.

And now we're going to bring them home.

That's right.

The Stone World's moon rocket will be made in Japan.

It's been a long, worldwide resource hunt.

And since we're here, does that mean that we're wrapping it up?

Yep.

This will be the last stop on our city-building tour.

We'll have all we need after this.

For realsies?

Oh, why, konnichi-wowsers!

Hey, look. I see some islands.

Heading just south of the equator.

We're in Indonesia!

Look at that stuff flow.

Come to mama.

We did collect quite a bit of it in Central South America.

But there's a reason they call this place the "home of rubber."

It makes me so happy I could cry.

We're gonna need all that we can carry.

Rubber City founded!!

What a long journey.

We left our home in Japan,

crossing the Pacific Ocean to explore the Americas.

We almost lost everything.

But through grit and determination,

we founded Corn City,

bringing people back to life every step of the way.

We built the city of superalloys,

the city of fluorite, the city of math and fuel,

then the city of aluminum.

And lastly, the city of rubber.

After all these years,

it's happening.

We're finally heading back to our homeland!

We'll be reunited with the ones we left behind.

All of humanity is coming together to achieve one goal,

probably for the first time.

One major milestone after another.

Yeah, we've united the entire world.

We'll get it done

build our return rocket so we can all celebrate our victory over Why-man.

Yeah, we'll bring everyone together.

'Cause if we're gonna build a rocket that can take us to the moon

then we gotta revive as many people as we can.

It'll take insane amounts of backbreaking labor to pull this off.

You've never really been the overly sentimental type, have you?

I wish we had a way to let them know,

to tell Ruri and all the others still petrified that this hell's almost over.

The real hell comes when Senku puts them all to work.

Surely they'll at least want a souvenir or two from our tour of the world.

And that's not wrong.

That was pretty much always the plan.

Oh, prezzy, for real?

You're the bomb, taking care of your besties.

Yeah, no. If I had to guess, he's got another scheme hiding up his sleeve.

There's always an ulterior motive if he's involved.

Oh, come on.

What have we done every place we've landed?

It's become our own tradition by now.

We always make it a point to whip up some local cuisine ASAP.

If we want to power the bodies of the folks we're waking up,

what better fuel than soul food?

Oh, the nums.

Now that's the way to gas somebody up,

have them stuff their faces with all their faves.

And all this time, I thought you just wanted some extra tasty meals.

I'll take all the tasty meals!

We're quite aware.

So in Japan, the soul food is--

Oh, hell yeah!

Man, how lucky is that?

Looks like we rolled up just in time for wild rice season.

Luck's got nothing to do with it.

Yeah, Senku would be pretty screwed if he had to rely on his otten-ray luck.

He planned to be exactly in this spot in April all along,

to catch the rice harvest on the way back home.

Rice acquired!!

So this is all we get?

It's not really that much.

You know, nature does things its own way.

That's exactly why we're getting humans in the loop by making a rice paddy.

We'll kick production into overdrive.

Go on ahead.

OK.

Next one, please.

It's coming right up.

Now you'll see, if you know the lengths of the three sides of the triangle,

you can find out its area pretty easily.

And no matter how large the area may be,

keep breaking it up into triangles,

and you can calculate the size of any plot of land.

Just a little to your left.

Yeah.

OK, you guys can go ahead and dig a channel straight to this spot.

Now it's our time to shine.

Yes, that's perfect.

Yay!

I know we need the supplies.

But are you sure we should start planting crops this early?

Isn't it supposed to be every other year?
