[00:07] Chrome
    So this thin hair-like stuff
    is going to turn into silver?
[00:10] Ginro
    Damn... I thought they were
    roots from some plant.
[00:19] Ginro
    That's going to become my silver spear, huh?
[00:22] Ginro
    Man, science sure is strange, isn't it?
[00:26] Ginro
    Speaking of which...
[00:28] Ginro
    Kinro, you already got your golden spear, ri—
[00:32] Ginro
    Oh, wait...
[00:33] Ginro
    Sorry! I didn't notice.
[00:35] Ginro
    Who would have thought we'd only get
    a silver spear, and not a gold one?
[00:39] Kohaku
    Ginro, move your arms, not your mouth!
[00:44] Chrome
    Hang on, though.
[00:45] Chrome
    Why are you only making a silver spear?
[00:48] Senku
    Because we need it to get the
    maximum danger materials.
[00:56] Kohaku
    Yes!
[00:57] Kohaku
    I finally have a silver spear!
[00:59] Kohaku
    Yay! Thanks, Senku!
[00:59] ---
    Yippee! Yippee!
[01:04] Senku
    You don't owe me one millimeter of thanks.
[01:07] Senku
    I didn't make that for you.
[01:10] Senku
    Come on, let's get moving.
SIGN    Bodyguard Ginro
[01:12] Senku
    Ginro, your job is to be the team's bodyguard.
[01:19] Ginro
    Bodyguard! Bodyguard!
[01:21] Ginro
    I'm a bodyguard!
[01:23] Ginro
    I'm Ginro!
[01:25] Ginro
    I'm Ginro!
[01:25] Kohaku
    Hey, this is the hot spring area that
    I draw hot water from all the time.
[01:30] Chrome
    I came all prepared because you said
    it was going to be "maximum danger."
[01:33] Senku
    It gets dangerous up ahead.
[01:36] Senku
    Ginro, quit messing around
    and hold your spear forward.
[01:40] ---
    Huh?
[01:41] Senku
    This silver spear is a sensor.
[01:43] Senku
    That's what I made it for.
[01:46] Senku
    Take a good look at the tip.
[01:48] Senku
    If that silver spear turns black...
[01:53] Ginro
    If it turns black...?
[01:57] Senku
    A few seconds later, you'll be dead.
[02:03] Senku
    You need to get away within 0.1 seconds.
[02:06] Senku
    We'll all run, too.
[02:08] Senku
    The enemy we're about to
    go up against will send us
[02:11] Senku
    to the afterlife with just one mistake.
[02:13] Senku
    This is the greatest hurdle
    in making sulfa drugs.
SIGN    Buddies Back to Back
[03:56] Chrome
    There isn't a single fish in this river.
[03:59] Senku
    I know.
[04:00] Senku
    Nothing but emerald green liverwort.
[04:03] Senku
    This is it for sure.
[04:04] Senku
    Our goal is upstream from here.
[04:07] Kohaku
    So the greatest hurdle is up ahead...
[04:10] Ginro
    It's okay.
[04:15] Ginro
    It's okay.
[04:17] Ginro
    It's okay. It's not black yet.
[04:19] Ginro
    It's okay.
[04:21] Ginro
    It's okay.
[04:22] Ginro
    It's okay.
[04:24] Ginro
    It's ok—
[04:26] Senku
    What the hell is the sensor doing
    walking at the back, Ginro?!
[04:30] Ginro
    Well, you said I was gonna die!
[04:31] Ginro
    I'm scared!
[04:34] Kohaku
    Want to switch places with me, then?
[04:36] Kohaku
    Hand over the silver spear.
[04:37] Ginro
    Never!
[04:38] Ginro
    I'll do it!
[04:39] Ginro
    I'll do it, all right?!
[04:42] Ginro
    It's okay.
[04:44] Ginro
    It's okay...
[04:47] Ginro
    I-I-I-It's okay...
[04:49] ---
    It's okay...
[04:50] ---
    It's okay...
[04:52] Ginro
    It's—
[04:54] Ginro
    Chrome, Senku, Kohaku-chan...
[05:01] Chrome
    We're here, Senku.
[05:03] Chrome
    I knew it.
[05:05] Chrome
    We've found the source of the materials
    that were our greatest hurdle.
[05:09] Kohaku
    I don't even know what we're here to gather,
[05:13] Kohaku
    but I can at least appreciate
    that this is our goal.
[05:16] Kohaku
    It's so divine and beautiful...
[05:20] Kohaku
    An entire spring of emerald green.
[05:46] Chrome
    What's up, Senku?
[05:47] Chrome
    Is this not our goal?
[05:49] Senku
    No, it is.
[05:51] Senku
    This is perfect.
[05:53] Senku
    It's this green water that
    we're here to collect.
[05:56] Senku
    But the geography bugs me.
[05:58] Senku
    The poison gases that form here,
[06:01] Senku
    hydrogen sulfide and sulfur
    dioxide, are heavier than air.
[06:05] Senku
    They settle in dips like this one.
[06:08] Chrome
    Is that what the silver spear's
    supposed to warn us about?
[06:12] Senku
    Yeah.
[06:13] Senku
    Silver reacts with hydrogen sulfide
    and turns black instantly...
[06:31] Senku
    Get back, Ginro!
[06:53] Sulfur lady
    How could you tell?!
[06:55] Sulfur lady
    I was so close to giving you eternal slumber!
[07:01] Ginro
    Go away!
[07:02] Kohaku
    Calm down! There's no one there!
[07:03] Kohaku
    There's no one there, Ginro!
[07:08] Kohaku
    It melted.
[07:09] Kohaku
    The bird's wing...
[07:11] Chrome
    What's the deal with this
    spring's water, Senku?!
[07:16] Senku
    It was discovered around the 8th century,
    in the midst of alchemy research.
[07:20] Senku
    In my time, it was a chemical
    that served as the foundation
[07:23] Senku
    for all kinds of chemical industries...
[07:30] Senku
    Sulfuric acid.
[07:32] Chrome
    And we can't make the cure-all drug for
    Ruri without this sulfuric acid stuff?
[07:37] Senku
    Nope.
[07:38] Senku
    We need to secure a source
    of sulfuric acid anyway,
[07:40] Senku
    or chemistry won't develop any further.
[07:44] Kohaku
    We'll have to push our way
    through to gather some.
[07:47] Kohaku
    I'll risk my life as many times
    as it takes to save Ruri-nee.
[07:51] Kohaku
    With my speed...
[07:54] Senku
    Back in my age, there was a group
[07:56] Senku
    that went to do research around an
    area of sulfuric acid like this one.
[08:01] Senku
    The man in front knelt for a moment,
    maybe to tie his shoelaces.
[08:07] (Flashback) Woman
    Sensei, what's wrong?
[08:13] Senku
    He was dead.
[08:16] Senku
    There was hydrogen sulfide at
    his head's height when he knelt.
[08:19] Senku
    This is an accident that actually happened.
[08:22] Senku
    Humans don't stand a chance when
    Mother Nature wants us dead.
[08:27] Senku
    It doesn't matter how stupidly
    fast you are, Kohaku.
[08:30] Kohaku
    Then what are we supposed to do, Senku?
[08:33] Kohaku
    I have to save Ruri-nee, no matter what!
[08:35] Senku
    What else?
[08:38] Senku
    We're going to make gas masks.
[08:43] Senku
    The only way to fight a chemical
    enemy is with chemistry.
[08:51] Senku
    We'll have to see how much poison
    we can breathe through this.
[08:54] Senku
    We can't rely on trial and error this time.
[09:00] Senku
    An error would mean our death.
[09:05] Chrome
    All right, my mask's next.
[09:07] Senku
    You won't need one.
[09:12] Senku
    Chrome, you aren't coming with
    us to get sulfuric acid anymore.
[09:16] Senku
    Stay here.
[09:17] Chrome
    What? Where's this coming fr—
[09:18] Senku
    Shut up and listen.
[09:20] Senku
    These gas masks aren't guaranteed to work.
[09:23] Senku
    Who's going to save Ruri if
    all the scientists go down?
[09:30] Senku
    All humans die eventually.
[09:32] Senku
    But knowledge doesn't.
[09:35] Senku
    It's been passed down for two million years.
[09:39] Senku
    Listen up, Chrome.
[09:41] Senku
    I'm going to pass down
    all the science I know,
[09:44] Senku
    all two million years of human
    civilization, to you, right now.
[09:51] Chrome
    Wait, wait, hang on! It's too soon!
[09:53] Chrome
    Quit talking like I'm
    replacing you or something!
[09:56] Chrome
    Jeez, that's so ominous!
[09:57] Senku
    Well, aren't you kind?
[10:00] Senku
    What are you, my girlfriend?
[10:03] Senku
    I don't have one millimeter
    of interest in dying, so relax.
[10:06] Senku
    But the only way to cure Ruri's disease is to
[10:10] Senku
    charge into the poison gas
    and get some sulfuric acid.
[10:14] Senku
    If the two of us do go down 
    together, in that instant,
[10:19] Senku
    all science will disappear
    from the face of the Earth.
[10:27] Chrome
    So I'm staying behind in case you die.
[10:31] Senku
    Yeah, after I pass down all
    my knowledge of science.
[10:38] Chrome
    I'm not taking it, if that's the case!
[10:43] Senku
    What are you, a kid?
[10:45] Senku
    Don't get so fussy about staying home—
[10:47] Chrome
    That's not the point!
[10:49] Chrome
    I have no intention of
    helping you with a plan
[10:51] Chrome
    that makes it okay for my friend to die!
[10:56] Chrome
    Sorry to disappoint you, Senku,
    but I'm not taking your knowledge.
[11:01] Chrome
    So if you croak, it's game over for science!
[11:06] Chrome
    You're coming back alive, ten billion percent!
[11:10] Chrome
    You have to, Senku!
[11:13] Chrome
    Besides, why are you,
    the key figure of science,
[11:16] Chrome
    doing the raid through the poison gas?
[11:19] Chrome
    Just use me or someone else.
[11:22] Chrome
    Senku, that's what you would call "logical."
[11:27] Chrome
    And yet, you're like,
    "Chrome, you're staying at home."
[11:29] Chrome
    You seem to think you need to protect me.
[11:32] Chrome
    What am I, your kid?
[11:35] Chrome
    Don't patronize me, asshole.
[11:40] Senku
    I'm not patronizing anyone, idiot.
[11:42] Senku
    My reasoning is logical.
[11:44] Senku
    I know everything about
    how the gas mask works
[11:48] Senku
    and about the materials we're going
    to get, so our best bet is for me to go.
[11:52] Senku
    That's all.
[11:53] Chrome
    That's not our best bet!
[11:57] Chrome
    The best bet is for us
    science users to tag team.
[12:01] Chrome
    We can save each other
    if it comes to that.
[12:03] Chrome
    Am I wrong?
[12:09] Senku
    When it comes to "that," we'll already
    be dead from the poison gas.
[12:12] Senku
    There's no saving each other.
[12:14] Chrome
    B-But there might be, like, an "Oh, shit,
    my leg's cramping!" type of situation!
[12:19] Senku
    Yeah, you're right.
[12:22] Senku
    It might be just 0.1 percent, but it
    would raise my chances of survival.
[12:29] Senku
    Taiju and Yuzuriha, was it?
[12:32] Senku
    They're in the Tsukasa Empire as spies, right?
[12:35] Senku
    Aren't they putting their lives on the line?
[12:37] Senku
    Aren't you and they trusting
    your lives to each other?
[12:41] Chrome
    If I'm your friend,
[12:42] Chrome
    neither higher nor lower than you,
    it's not "I'll protect you."
[12:48] Chrome
    That's the wrong line!
[12:55] Senku
    Damn it, now we have to make
    another gas mask, thanks to you.
[13:02] Senku
    Chrome, you can trust me with your life.
[13:06] Chrome
    Yeah.
[13:07] Chrome
    Same to you, Senku.
[13:13] Ruri
    Kohaku, now that Mother is dead,
    I have to tell you something important.
[13:19] (Flashback) Ruri
    Do you know what the most important
    duty of the priestess is?
[13:23] (Flashback) Ruri
    The Hundred Tales.
[13:26] (Flashback) Ruri
    The knowledge kept within the
    hundred stories must be passed down
[13:29] (Flashback) Ruri
    from generation to generation, without fail.
[13:33] (Flashback) Kokuyo
    You must understand, Kohaku.
[13:35] (Flashback) Kokuyo
    Ruri won't live long.
[13:39] (Flashback) Kokuyo
    We must avoid the breach of
    the Hundred Tales at any cost.
[13:43] (Flashback) Kokuyo
    You're healthy.
[13:44] (Flashback) Kokuyo
    You must be the next priestess after Ruri...
[13:46] (Flashback) Kohaku
    I'm not going to be the
    successor, if that's the case.
[13:50] (Flashback) Kohaku
    I have no intention of helping with a
    plan that makes it okay for Ruri to die!
[13:57] (Flashback) Kokuyo
    Where are you going, Kohaku?!
[14:03] Kohaku
    If I'm in a position to take
    on the priestess's role,
[14:05] Kohaku
    Ruri-nee will have no reason to keep going.
[14:09] (Flashback) Kohaku
    That's it! I just need to make Father hate me.
[14:14] (Flashback) Kohaku
    I'll be a rambunctious girl.
[14:16] (Flashback) Kohaku
    Someone utterly unfit
    to become the priestess.
[14:19] (Flashback) Kohaku
    I'll carry the healing water.
[14:20] (Flashback) Kohaku
    However many thousands of times
    I have to do it, I'll cure Ruri-nee!
[14:30] Kohaku
    Chrome, you and I are alike.
[14:35] Kohaku
    Everyone would be mighty happy if
    Ruri-nee were to marry a man like you.
[14:42] Kohaku
    But the heavens didn't bless
    you with the ability to fight.
[14:46] Kohaku
    God's not very considerate, is He?
[14:50] Kohaku
    If all goes according to our plan,
    Ruri-nee will be marrying Kinro or Ginro.
[14:56] Kohaku
    If it'd be any consolation, would you
    want me to be your wife in her stead?
[15:05] Chrome
    You're nothing alike.
[15:06] Chrome
    Ruri's ladylike, but you're a gorilla.
[15:13] Chrome
    See? Gorilla.
[15:15] Chrome
    What was that about, anyway?
[15:17] Chrome
    Do you have a crush on me or something?
[15:19] Kohaku
    Not in the slightest.
[15:21] Chrome
    I didn't think so.
[15:22] Chrome
    So don't say stuff like that.
[15:27] Senku
    This is the same as when we
    made Edison's light bulb.
[15:30] Senku
    First, we steam-roast some bamboo.
[15:32] Chrome
    You can use glass that way, too?
[15:35] Senku
    Add potassium carbonate,
    which is extracted from ash.
[15:38] Senku
    We also used this to make ramen.
[15:42] Senku
    That gives us this black powder,
[15:44] Senku
    activated charcoal, mixed well
    with potassium carbonate.
[15:47] Senku
    It'll neutralize and catch the poison gas.
[15:50] Chrome
    Now we have a chemical
    barrier against poison gas!
SIGN    Acquired gas mask!!
[15:55] Chrome
    Time for the two of us science
    users to tag team for a rematch!
[16:01] Senku
    We're gonna get over the greatest hurdle
[16:03] Senku
    and bring home some sulfuric
    acid for the cure-all drug.
[16:21] Ginro
    This is totally the curse of
    that fairy from the spring!
[16:25] Ginro
    That bird died!
[16:27] Ginro
    My silver spear turned black!
[16:28] Ginro
    I'm never going back there again!
[16:32] Chrome
    Damn it, Ginro...
[16:34] Chrome
    Come on, let's go!
[16:35] Senku
    Whatever. Just stay at home.
[16:38] Senku
    You'll only slow us down.
[16:40] Senku
    But that's not a curse.
[16:43] Senku
    It's science.
[16:45] Senku
    Rub the black sulfuric acid sludge
[16:46] Senku
    with some kind of alkaline base,
    and it'll turn silver again.
[16:49] Senku
    Even rubbing it against
    the warm ashes will do it.
[16:53] Chrome
    The poison gas sensor's back!
[16:55] Senku
    Let's get going to the sulfuric acid spring.
[17:10] (Flashback) Senku
    He was dead.
[17:12] Chrome
    There are no do-overs.
[17:16] Chrome
    Do we really stand a chance against
    this instant-death poison gas?
[17:24] Chrome
    Holy crap!
[17:26] Chrome
    Are you seriously just walking up to it?!
[17:28] Senku
    If you stand around huffing
    and puffing in fear,
[17:31] Senku
    you'll end up overwhelming the
    gas mask's ability to clean the air.
[17:36] Senku
    It's a ridiculously simple concept.
[17:38] Senku
    Freak out too much, and you die.
[17:40] Senku
    Now you know. Come on.
[17:41] Chrome
    I get the reasoning, but...
[17:44] Chrome
    Damn it, Senku, I'm not as ballsy as you—
[18:03] Kaseki
    Sheesh, why am I sitting
    here helping you again?
[18:09] Ginro
    Senku and Chrome are both wrong.
[18:12] Ginro
    How is it not scary?!
[18:15] Ginro
    You might die!
[18:16] Ginro
    Jeez, I hate it when people do that!
[18:19] Ginro
    They act all brave,
    but they're actually reckless!
[18:22] Kaseki
    Considering you'd rather run
    your mouth than shut up and run,
[18:26] Kaseki
    I'm guessing you feel like
    a loser for being so weak.
[18:31] Ginro
    I don't...
[18:32] Kaseki
    Don't worry, Ginro.
[18:35] Kaseki
    You aren't weak at all.
[18:39] Kaseki
    Fear is the secret to a long life.
[18:42] Kaseki
    Isn't it convincing when an
    old fogy tells you that?
[18:46] Kaseki
    I used to be a wimp myself.
[18:48] Kaseki
    They're really scared inside, too.
[18:52] Kaseki
    No one is immune to fear.
[18:58] Ginro
    That's right.
[18:59] Ginro
    I hadn't thought about it before,
[19:02] Ginro
    but imagine how scary it must be
[19:04] Ginro
    for Kinro, with his fuzzy eyes,
    to go up against Magma.
[19:09] Kaseki
    But we try to overcome fear for
    the sake of something dear to us,
[19:12] Kaseki
    using reason and willpower.
[19:16] Kaseki
    That's what it looks like to me, at least.
[19:24] (Flashback) Kohaku
    I want to save my sister's life.
[19:33] Kaseki
    Whoops, I got carried away
    and made another gas mask.
[19:38] Kaseki
    I guess I'll leave it here,
    since I have no use for it.
[20:02] Chrome
    Senku!
[20:03] Chrome
    The end of your gas mask is melting!
    It's about to come loose!
[20:08] Senku
    That was a close one.
[20:09] Senku
    Good thing we came here together—
[20:18] Chrome
    Shit.
[20:19] Chrome
    This is actually bad.
[20:21] Chrome
    Senku's trying to catch up to me.
[20:24] Chrome
    Don't bother.
[20:26] Chrome
    There's no chance in hell.
[20:28] Chrome
    Damn it! It was such a small mistake...
[20:32] Chrome
    Take care of Ruri for me.
[20:42] Senku
    Ginro!
[20:52] Ginro
    You're too heavy!
[20:54] Senku
    Control your breathing, Ginro!
[20:56] Senku
    Your gas mask can't keep
    up with your air intake.
[20:58] Ginro
    It can't?
[21:01] Ginro
    Is the poison gas going to kill me?
[21:02] Ginro
    Am I going to die right now?
[21:06] Senku
    All the activated charcoal and
    potassium carbonate will keep you
[21:09] Senku
    safe from the poison gas, I promise!
[21:10] Senku
    As long as you control your breath!
