**[00:03] (Flashback) Xeno**
Hold your fire, Stan!
**[00:07] (Flashback) Xeno**
Doctor Taiju was a body double.
**[00:12] (Flashback) Xeno**
The true enemy leader...
**[00:14] (Flashback) Xeno**
The OP scientist...
**[00:19] (Flashback) Xeno**
is Senku.
**[00:21] (Flashback) Xeno**
Ishigami Senku.
**[00:25] (Flashback) Ryusui**
Sniper!
**[00:26] (Flashback) Ryusui**
There's a sniper!
**[00:30] Luna**
*Did they catch me?!*
**[00:32] Stanley**
*Idiot! Stop looking at me, Luna!*
**[00:35] Stanley**
*They'll know where I am!*
**[00:38] Stanley**
*No, that's not it.*
**[00:40] Stanley**
*Look!*
**[00:43] Stanley**
*The OP science leader...*
**[00:45] Stanley**
*The smart one is one of those three.*
**[00:48] Stanley**
*If the target is as clever as Xeno says,*
**[00:52] Stanley**
* he'll no doubt notice where you're*
* looking and turn to face me.*
**[00:58] Stanley**
*He'll naturally smoke himself out.*
**[01:03] Stanley**
*Heya, Ishigami Senku.*
**[01:08] (Flashback) Stanley**
Xeno, let me ask one more time, just in case.
**[01:14] Stanley**
*You're sure, right?*
**[01:16] Stanley**
*I'm going to kill him.*
**[01:17] Stanley**
*There's no taking it back.*
**[01:22] (Flashback) Xeno**
Yeah.
**[01:23] (Flashback) Xeno**
Go ahead.
***SIGN*** Light of Science
**[03:17] Yuzuriha**
Gunfire?!
**[03:18] Ginro**
They're coming for us! The bullets are coming!
**[03:20] Ryusui**
No! It landed before the sound came!
**[03:25] Ryusui**
They're already done firing.
**[03:33] Taiju**
S-Senku!
**[03:52] Stanley**
Our work's done.
**[03:54] Stanley**
I've taken down the enemy science leader.
**[04:00] Stanley**
You two stay here.
**[04:03] Stanley**
Keep an eye on them.
**[04:04] Carlos**
Wait...
**[04:05] Max**
What about the lady?!
**[04:07] Stanley**
Leave her or save her. Up to you.
**[04:11] Stanley**
It's not my problem.
**[04:14] Max**
Damn it!
**[04:17] Carlos**
Miss...
**[04:20] Luna**
*Wh-Wh-Wh-Wh-Wh-What do I do?!*
**[04:25] Ginro**
Senku!
**[04:26] Ginro**
They killed him!
**[04:31] Ryusui**
Calm down!
**[04:32] Ryusui**
"We've erased the enemy science leader.
They won't catch up to us in firepower now."
**[04:37] Ryusui**
"Now we just wait and put on
pressure until the kids surrender."
**[04:43] Ryusui**
The enemy isn't expecting anything right now.
**[04:45] Ryusui**
It's our opportunity to strike back!
**[04:47] Ryusui**
Am I right?
**[04:52] Yo**
Okay, maybe so, but...
**[04:54] Yo**
I get it, but...
**[04:56] Yo**
It's not about taking an opportunity right now.
**[04:59] Yo**
Not in this situation!
**[05:01] Ginro**
He's right!
**[05:02] Ginro**
Can we at least make a grave for Senku?
**[05:07] Stanley**
Don't give up just yet.
**[05:15] Francois**
"Heh, heh. I'm not dead, dumbass."
**[05:24] Francois**
"The bullet's clean out," he seems to be saying.
**[05:31] Taiju**
You don't need to talk, Senku!
**[05:33] Taiju**
Let your body rest!
**[05:35] Ginro**
Thank goodness!
**[05:36] Ginro**
He barely—
**[05:38] Matsukaze**
If I may...
**[05:39] Kinro**
Don't let them know!
**[05:41] Kinro**
The enemy could be listening!
**[05:43] Kaseki**
You softened the bullet's impact?
**[05:46] Kaseki**
With this bag of flour and water?
**[05:51] Kaseki**
You do the damnedest things.
**[05:55] Francois**
"Yeah. Although if it had been a head shot,
I'd be dead ten billion percent."
**[06:01] Francois**
"But there's a chance that only I know
the recipe for the revival fluid."
**[06:05] Francois**
"They must have wanted to give
me time to leave a will."
**[06:10] Francois**
"I knew they would aim for my chest."
**[06:16] Francois**
That's what he seems to be saying.
**[06:18] Francois**
In English, "If it was a head shot,
it would have been an instant death."
**[06:23] Yo**
Wow, simultaneous interpretation!
**[06:25] Minami**
Stop talking already!
**[06:28] Luna**
*Wow.*
**[06:31] Luna**
*I can't believe he thought that far ahead.*
**[06:35] Luna**
*In that situation, no less.*
**[06:40] Taiju**
He's unconscious!
**[06:42] Taiju**
Was it fatal after all?!
**[06:44] Francois**
I'll do what I can.
**[06:46] Francois**
But beyond that, we'll need a doctor.
**[07:04] Luna**
*I think...*
**[07:05] Luna**
*I mean, my memory's really, really shaky, but...*
**[07:09] Luna**
*If you squeeze the upper arm,*
**[07:12] Luna**
*the pulse at the wrist vanishes.*
***SIGN*** Low Blood Pressure
Pulse vanishes with a light press
***SIGN*** High Blood Pressure
Pulse vanishes with a firm press
**[07:15] Luna**
* If it only takes a light press,*
* it's low blood pressure.*
**[07:18] Luna**
* If it takes a firm press,*
* it's high blood pressure.*
**[07:22] Luna**
*And you can get a reading that way or something.*
**[07:25] Luna**
His blood pressure's down.
**[07:27] Ryusui**
Luna, are you a doctor?
**[07:30] Luna**
No, no, no!
**[07:31] Luna**
Of course not! I'm just a kid!
**[07:35] Luna**
It's just that I was a student...
**[07:38] Luna**
in medical school.
**[07:44] Luna**
* I'm gonna become a capable woman*
* and net myself a smart guy!*
**[07:50] Luna**
But I only got in through my dad's connections.
**[07:54] Luna**
I paid a ton of attention in class
so that no one would complain,
**[07:59] Luna**
but I had no idea what was going on.
**[08:02] Luna**
I ended up being the only one flunking.
**[08:06] Taiju**
Please!
**[08:09] Taiju**
Please, Luna!
**[08:11] Taiju**
We have no one else.
**[08:16] Taiju**
No one.
**[08:19] Taiju**
Senku is our friend.
**[08:24] Taiju**
Please.
**[08:26] Taiju**
Save him.
**[08:40] Chrome**
Damn it, this place...
**[08:42] Chrome**
Where do we even attack from?
**[08:44] Chrome**
They'll see us no matter what.
**[08:47] Chrome**
They're just gonna fill us with arrows.
**[08:50] Kohaku**
Indeed. Arrows I might be able to deal with...
**[08:54] Hyoga**
Actually, we're more likely to be
shredded by machine gun fire.
**[08:58] Chrome**
Shit.
**[08:59] Chrome**
Right, they're another Kingdom of Science.
**[09:13] Kohaku**
We've got some mighty
reinforcements with us now!
**[09:16] Chrome**
How did you find us here?
**[09:19] Suika**
Gen left a trail of flower petals for us.
**[09:22] Suika**
We followed them here.
**[09:26] Tsukasa**
So that's the enemy headquarters.
**[09:29] Tsukasa**
I'd like for us to make it through
the corn fields during the night...
**[09:32] Tsukasa**
But it's too open. It won't work.
**[09:36] Tsukasa**
The water would be closer,
but there aren't enough obstructions.
**[09:40] Hyoga**
If only we could sneak into their castle...
**[09:43] Hyoga**
I would be unmatched in close-quarters combat.
**[09:46] Ukyo**
But on top of that, we'd need to capture
Doctor Xeno and make an escape.
**[09:53] Tsukasa**
We may have to dig.
**[09:56] Hyoga**
Indeed.
**[09:58] Kohaku**
Dig?
**[09:59] Ukyo**
You don't mean...
**[10:02] Tsukasa**
Yeah.
**[10:04] Tsukasa**
It's *The Great Escape* in reverse.
**[10:06] Tsukasa**
We'll craft an underground
path into the enemy castle.
**[10:10] Tsukasa**
We're making a tunnel.
**[10:12] Chrome**
O-Oh, shit!
**[10:14] Suika**
Th-That's too much work!
**[10:18] Hyoga**
We'll need to ask Senku-kun
for all the digging equipment.
**[10:24] Chrome**
R-Right.
**[10:28] Ukyo**
Speak of the devil.
**[10:30] Ukyo**
It's a call from the *Perseus*.
**[10:33] Ryusui**
*4-3. 3-2. 3-3. 3-2.*
**[10:38] Chrome**
Huh?
**[10:38] Kohaku**
Why is Ryusui suddenly chanting random numbers?
**[10:41] Ryusui**
*7-4. 7-6. 4-7. 4-3. 1-1.*
**[10:41] Kohaku**
Is he messing around?
**[10:43] Ukyo**
It's the Uesugi cipher.
**[10:46] Ukyo**
Warlord Uesugi Kenshin used this
cipher during the Warring States era.
**[10:50] Ukyo**
The way it works is really simple.
**[10:53] Ukyo**
You convey a message by speaking the
numbers that correspond to the kana chart.
**[10:57] Hyoga**
As proper as Doctor Xeno may be,
**[11:00] Hyoga**
I doubt many people outside of Japan
would know the Iroha syllabary poem.
**[11:05] Ukyo**
It's such low-tech encryption
compared to the enemy's.
**[11:08] Ukyo**
It's simple but effective.
**[11:10] Ukyo**
Although they'll eventually crack it with
frequency analysis if we send long messages.
**[11:14] Kohaku**
What is he telling us with
this so-called "cipher"?
**[11:17] Ryusui**
*6-3. 5-7. 2-4.*
**[11:22] Ukyo**
Senku's been sniped.
**[11:28] Ukyo**
It's all right. He's still alive.
**[11:33] Hyoga**
But I suspect he's in no state
to make us science tools.
**[11:39] Kohaku**
We still need to dig.
**[11:42] Kohaku**
Without science, if we must.
**[11:46] Ukyo**
We have a message from Senku.
**[11:49] Ukyo**
Just three characters.
**[11:51] Ukyo**
4-7.
**[11:54] Ukyo**
1-2.
**[11:57] Ukyo**
4-2.
**[12:01] Senku**
Chrome.
**[12:22] Senku**
You know what to do, don't you?
**[12:29] (Flashback) Byakuya**
No matter the situation,
humanity, ten billion percent,
**[12:34] (Flashback) Byakuya**
always produces a greedy bastard who
wants to know everything about the world.
**[12:43] Senku**
You're the scientist now,
**[12:48] Senku**
Doctor Chrome.
**[13:00] Chrome**
* We're crafting a secret tunnel*
* to Doctor Xeno's main base.*
**[13:07] Chrome**
*With the power of science.*
**[13:10] Chrome**
* But Senku's been shot.*
* He's on absolute bed rest.*
**[13:14] Chrome**
*So then, who?*
**[13:16] Chrome**
*Can I really do this?*
**[13:20] Chrome**
* Me? The kid who's been coloring*
* flames and calling it sorcery?*
**[13:26] Chrome**
*No...*
**[13:29] Chrome**
* It's not about whether I can do it*
* or not. There isn't anyone else!*
**[13:34] Chrome**
*I'm science user Chrome.*
**[13:36] Chrome**
I'll make it all!
**[13:39] Chrome**
Road map and all!
**[13:45] Tsukasa**
We'll need time.
**[13:49] Tsukasa**
At least two weeks.
**[13:55] Ryusui**
Doctor Xeno's side is
under the impression that
**[13:57] Ryusui**
they've defeated Senku,
and with him, the threat of science.
**[14:01] Ryusui**
Which means they'll be ordering
our surrender imminently.
**[14:04] Magma**
Surrender? You're a moron!
**[14:07] Magma**
We'd never do that!
**[14:08] Ginro**
But what if they keep telling us to surrender?
**[14:12] Nikki**
Hyoga's right. They'll eventually come
at us with high-speed pirate ships.
**[14:18] Ryusui**
Will that be tomorrow? Or a month from now?
**[14:21] Ryusui**
That, we don't know.
**[14:23] Ryusui**
But make them think brute force is
risky and that it'd be wise to go slow.
**[14:28] Ryusui**
Skew their assessment in that direction.
**[14:32] Ryusui**
Am I right?
**[14:37] Francois**
"Yeah, we're gonna buy us a shit ton of time."
**[14:41] Francois**
"Ukyo has the real Medusa on him."
**[14:45] Francois**
"It'll be a special gift for Doctor Xeno."
**[14:49] Taiju**
What?!
**[14:59] Guard**
What's this?
**[15:02] Ginro**
Wh-Wh-Why are we handing it over to them?!
**[15:05] Ginro**
The Medusa is our special weapon!
**[15:07] Nikki**
It's out of battery anyway.
**[15:09] Ginro**
Still, though!
**[15:13] Ryusui**
I see now.
**[15:15] Ryusui**
A scientist of Doctor Xeno's stature
will understand the moment he sees it.
**[15:20] Ryusui**
He'll know that it's an object of superhuman
science beyond anything from the 21st century.
**[15:25] Kinro**
Will that be sufficient intimidation?
**[15:28] Ryusui**
What a pedestrian concern.
**[15:30] Ryusui**
It'll come with fake commentary, of course.
**[15:32] Minami**
From who?!
**[15:35] Minami**
Um...
**[15:36] Minami**
So you want me to read the situation
and tell a convenient lie,
**[15:39] Minami**
saying, "This is a petrification
weapon. We have more"?
**[15:42] Minami**
Are you telling me there's someone with
the enemy who can convey such a bluff?
**[15:50] Gen**
Is that what I think it is?!
**[15:51] Gen**
A petrification weapon?!
**[15:57] Xeno**
You know of it, Mr. Gen?
**[16:05] Gen**
So *that* happened, and we picked up
a ton of them on a southern island.
**[16:12] Gen**
It's a *super* old out-of-place
artifact from *way* back,
**[16:16] Gen**
so I guess the one they shot at us was a dud.
**[16:19] Gen**
Otherwise, we'd all have
been turned into stone.
**[16:24] Gen**
Oh, no!
**[16:26] Gen**
*That should about do it, right, Senku-chan?*
**[16:28] Gen**
* You'd only hand over the actual*
* petrification device if it was a bluff.*
**[16:35] Brody**
That's some real bullshit, you bat bastard!
**[16:39] Brody**
You lied about the leader already.
**[16:42] Brody**
Doctor Taiju, my ass! It was Doctor Senku!
**[16:46] Gen**
For real?!
**[16:48] Gen**
They had me fooled!
**[16:49] Gen**
They were together all the time,
come to think of it...
**[16:53] Gen**
Senku-chan was the actual talented scientist?
**[16:59] Xeno**
Setting aside Mr. Gen's trustworthiness,
**[17:03] Xeno**
it's indisputable that this elegant machine
is beyond the technology of the old world.
**[17:09] Stanley**
How is it triggered?
**[17:11] Stanley**
How long does it activate?
**[17:13] Stanley**
And what's its range?
**[17:15] Maya**
Stanley, you're back!
**[17:20] Gen**
I'm sorry, Stanley-chan.
**[17:23] Gen**
Only the battle team knows the details.
**[17:27] Gen**
All I'm aware of...
**[17:30] Gen**
is that just like the evil petrification beam
**[17:33] Gen**
from thousands of years ago, it's inescapable.
**[17:37] Gen**
Rush into their ship,
and they might petrify all of us.
**[17:45] Xeno**
Yeah, it *is* unexplained science, after all.
**[17:48] Xeno**
We have no way to know if it's true or not.
**[17:51] Xeno**
But either way...
**[18:01] Maya**
I was the kind of girl
used to play by the dumpster!
**[18:03] Gen**
So loud!
**[18:05] Gen**
What?! Is she singing?
**[18:07] Gen**
She's trying to!
**[18:09] Maya**
I didn't care what they say
because I found my treasure!
**[18:09] Gen**
It's a total weapon of mass destruction!
**[18:19] Stanley**
Do we still not have *the thing*?
**[18:22] Stanley**
With that, they won't even have time
to throw the petrification weapon.
**[18:30] Stanley**
I can easily overwhelm the enemy ship.
**[18:35] Xeno**
Doctor Brody, we're counting
on your genius mechanic skills.
**[18:41] Xeno**
When can we expect it?
**[18:44] Xeno**
In a month? Six months?
**[18:50] Brody**
Do you know who I am, son?
**[18:53] Brody**
Two weeks.
**[18:55] Brody**
I'll finish it in two weeks.
**[18:57] Xeno**
Magnificent.
**[18:59] Xeno**
An elegant answer indeed.
**[19:03] Gen**
*So they aren't letting me in on it.*
**[19:03] Gen**
You can feel it in the air!
**[19:06] Gen**
*They're making something.*
**[19:10] Gen**
*Some kind of science item that Senku-chan*
**[19:14] Gen**
*would have never thought of.*
**[19:17] Gen**
*I think I managed to buy time.*
**[19:22] Gen**
* But with time, the enemy's*
* science will make progress, too.*
**[19:30] Gen**
*There's a time limit on this.*
**[19:40] Gen**
*It's a science vs. science craft-off!*
**[19:46] Chrome**
I'm not gonna be able to do this alone.
**[19:49] Chrome**
I'm counting on all of you!
**[19:51] Suika**
I'm gonna make myself useful!
**[19:59] Kohaku**
Are we getting some kind of measurement
by just staring at the enemy base?
**[20:04] Ukyo**
It's called trigonometrical surveying.
**[20:06] Ukyo**
We just need the length of one line
and the angle to the other side,
**[20:09] Ukyo**
and we can calculate the distance that we
need to dig without actually going there.
**[20:13] Chrome**
Add this number, and... no, wait, multiply...
**[20:17] Chrome**
Um...
**[20:22] Kohaku**
Arithmetic!
**[20:24] Kohaku**
I remember you getting reamed by Senku in
that number battle you challenged him to.
**[20:29] Chrome**
I only knew the times table
up to nine at the time.
**[20:33] Chrome**
Not that I'm much better now.
**[20:38] Suika**
That's amazing!
**[20:39] Kohaku**
This is so complicated.
**[20:42] Chrome**
We're just getting started.
**[20:44] Chrome**
There's a lot more to do.

I bet they didn't have this in
21st century science, even!
**[21:38] Kohaku; Suika**
Dirt-ripping loop-knife?

That's right.

But using this...
**[21:58] Tsukasa**
Yup. We can advance through the dirt.
**[22:01] Chrome**
That's right!
**[22:03] Chrome**
We're gonna bust right in!
**[22:06] Chrome**
Into the enemy base!
**[22:10] Chrome**
Using the science that I made!
