[00:01] Yamagami
    Allow me to address you
    regarding my transfer.
SIGN    Fuwa Fire Station
[00:05] Yamagami
    I, Fire Lieutenant Yamagami Kyosuke,
[00:07] Yamagami
    have been ordered to head up
    specialized education
[00:11] Yamagami
    at the Fire Academy's Education
    and Training Division as of July 1st.
[00:14] Yamagami
    I have been with Fuwa Rescue
    for one year and eight months!
[00:17] Yamagami
    I have zero regrets!
[00:19] Yamagami
    Some years ago,
[00:21] Yamagami
    a senior member told me that there are
     three kinds of lives at rescue scenes.
[00:25] Yamagami
    The lives of the survivors,
[00:27] Yamagami
    the lives of your fellow rescuers,
[00:28] Yamagami
    and your own life.
[00:30] Yamagami
    The special rescue squads are
    special because they can leverage
[00:33] Shun(m)
    I heard that Captain Yamagami was the one
    who pulled me up into the rescue squad...
[00:35] Yamagami
    the preciousness and importance of those
    three lives during daily practice.
[00:39] Yamagami
    I believe that this fact also allows them
    to be at the very front of any emergency.
[00:42] Shun(m)
    He's the first person in my life...
[00:44] Yamagami(background)
    I was only able to function as
    the captain of Fuwa Rescue
[00:45] Shun(m)
    who ever acknowledged me.
[00:49] Yamagami
    because I had the support of
    my superiors and colleagues,
[00:51] Yamagami
    and, of course, all of you who are here today.
[00:56] Yamagami
    I thank you all from the bottom of my heart.
[00:58] Yamagami
    Though I will be moving
    on to a new position,
[01:01] Yamagami
    I solemnly vow to never allow the
    orange flower in my heart to wilt!
SIGN    Omurou can't wait to get into the circle
[01:07] Voice
    Everyone, bow!
[01:10] Voice
    Rise!
[01:12] Crowd
    Hooray!
[01:15] Crowd
    Hooray!
[01:19] (Flashback) Yamagami
    On that one single point,
    I will acknowledge you.
[01:24] Crowd
    Hooray!
[01:27] Crowd
    Hooray!
[01:29] (Flashback) Yamagami
    Put on those patches and grow
    into amazing squad members!
[01:33] Crowd
    Hooray!

    I mean, I'll accept it.

    Even I will accept it.
[03:26] Itou
    But who gets transferred
    at this time of the year?
[03:30] Itou
    And then, the rescue
    competition is coming up.
[03:33] Itou
    Couldn't it wait until nationals?
[03:37] Itou
    I mean, Fuwa Rescue has become the unit it is
     today because you were at the helm, right?
[03:41] Yamagami
    You're too kind, sir.
[03:45] Itou
    I mean, look.
[03:47] Itou
    Team 1 and Team 3 are here
     even though they're off duty.
[03:51] Itou
    They showed up for you.
[03:53] Itou
    You are loved.
[03:55] Itou
    That's why I don't want you to leave.

[03:59] Itou
    You won't get a chance to be a
    national champion like this again, either.
[04:05] Itou
    I'll accept it because that's HR.
[04:08] Itou
    Even I will.
[04:11] All
    Wow, the station chief is
    really not taking it quietly.
[04:16] Shun(m)
    I wonder how Captain Yamagami
    feels about all this.
[04:24] Shun
    Daigo, did you know?
[04:26] Shun
    Captain Yamagami's wife is a
    nurse over in that hospital.
[04:31] Shun
    She's been there for over ten years.
[04:41] Shun(M)
    Oh. I get it.
[04:47] (Flashback) Daigo
    Can you keep this to yourself?
[04:51] Shun(m)
    Captain Yamagami knew about Daigo's
    entire situation all along.
[04:56] Shun(m)
    He probably even knows how
    much it's weighing on him.
[05:04] Shun(m)
    I wonder how Captain Yamagami felt when he
    saw Daigo pull off all those insane rescues.
[05:18] Sakura
    Thank you for everything, Captain Yamagami.
[05:20] Sakura
    I'm sure you'll do great in
    your new division as well.
[05:23] Yamagami
    Thank you very much, Dr. Nagata.
[05:26] Itou
    Well, thank you for coming over!
[05:29] Itou
    Did you just come from your
    night shift, Dr. Nagata?
[05:32] Nagata
    Yes. I've learned so much
    from Captain Yamagami.
[05:37] Shun
    Who... is that?
[05:40] Daigo
    That's Dr. Nagata.
[05:42] Daigo
    I believe she's with the DMAT over
    at Hinomoto University Hospital.

    I saw her in Tokyo Firefighter.
[05:53] Igarashi
    Daigo, the gear is completely new,
    and hasn't been broken in, so be careful.
[05:57] Daigo
    Yes, sir.
[05:58] Yamagami
    Nagata-sensei, that's Toake Daigo.
[06:06] Sakura
    He's so young.
[06:09] Sakura
    I never could have imagined it
[06:11] Sakura
    back then.
[06:14] (Flashback) Sakura
    He was very lucky to be rescued
    by such an experienced person.
[06:19] (Flashback) Sakura
    Accurately locating the median nerve in that
    situation would be difficult even for a doctor.
[06:25] (Flashback) Sakura
    Let alone cutting the rebar with
    an air saw without touching it.
[06:31] Yamagami
    Yes.
[06:32] Yamagami
    It doesn't match, does it?
[06:34] Yamagami
    The skill with the age.
[06:35] Yamagami
    The career.
[06:37] Yamagami
    There's a reason why
    Toake's become like this.
[06:42] Nagata
    A reason?
[06:44] Yamagami
    His dedication really is wonderful.
[06:47] Yamagami
    However...
[06:53] Yamagami
    Nagata-sensei!
[06:55] Yamagami
    I'd like you to keep an eye on Toake.
[06:57] Yamagami
    Please.

    Another call to emergency services
    reports that the fire is still burning.
[07:54] Yamagami
    What's the word on the 252s?
[07:56] Igarashi
    According to the first responders,
[07:58] Igarashi
    they are unable to evacuate
    for an unknown reason.
[08:04] Igarashi
    Copy that!
[08:05] Igarashi
    There seem to be powder
    materials inside the building.
[08:12] Usui
    The fire is spreading, right?
[08:14] Usui
    If that powder becomes
    airborne and ignites...
[08:25] Shun(M)
    A dust explosion.
[08:27] Shun(M)

    Four 252s secured.
[09:09] Shun
    Is there anybody else inside?

    This is an emergency door.
[09:16] Shun(m)
    Why didn't it open?

[09:25] Igarashi
    The other squad is already
    working to extinguish the fire,
[09:27] Igarashi
    so we'll be entering here.
[09:29] Igarashi
    Split into groups of two,
    and search for survivors.
[09:31] All
    Yes, sir!
[09:32] Yamagami
    According to the facility manager,
[09:35] Yamagami
    only the four people already
    rescued were working today.
[09:38] Yamagami
    But we still can't let our guard down!
[09:41] Igarashi
    They have 12 rotary presses.
[09:43] Igarashi
    There are many blind spots.
[09:45] Igarashi
    Let's go clockwise and

    3HR will enter the first floor to determine
     what kinds of powder materials are present.
[10:16] Yurie
    Wait... isn't that...

[10:38] Igarashi
    No 252s!
[10:40] Igarashi
    Captain Yamagami, what about
    that powder material?
[10:45] Yamagami
    I see. Copy that.
[10:47] Yamagami
    It is not toxic!
[10:49] Yamagami
    It's something akin to flour.
[10:51] Yamagami
    It's used to prevent the freshly-printed
    products from sticking to each other.
[10:55] Yamagami
    It's securely sealed and kept in the
    material storage on the first floor.
[10:58] Igarashi
    All right!
[11:00] Igarashi
    It looks like we don't have to
    worry about a dust explosion.
[11:03] Narrator
    A dust explosion happens when
    airborne particles smaller
[11:08] Narrator
    than 500 micrometers reach
    a certain concentration.
[11:11] Narrator
    A spark or static electricity can cause them to
    ignite, resulting in an explosive combustion.
SIGN    Oxygen
SIGN    Particle
[11:19] Narrator
    The particles are very fine,
[11:22] Narrator
    meaning they have a very high surface
    area compared to their volume.
[11:28] Narrator
    As there is always oxygen
    surrounding these particles,
[11:32] Narrator
    they combust extremely well.
[11:34] Narrator
    Should any one particle be ignited,
[11:38] Narrator
    it causes a chain reaction
    which culminates in an explosion.

[12:02] Igarashi
    The smoke ducts are working,
[12:04] Igarashi
    so visibility inside is somewhat okay.
[12:08] Igarashi
    But the intensity of the
    fire simply won't go down.

    Hey, Daigo...
[12:30] Shun
    The color of the smoke over there changed.
[12:34] Shun
    Isn't that kind of weird?
[12:37] Shun
    Do you also see that something's in the smoke?
[12:41] Daigo
    You're right!
[12:42] Shun
    Could it be?
[12:43] Shun
    Is that smoke duct sucking up
    some sort of powder?

    But... I mean...

[12:53] Igarashi
    That's shouldn't be.
[12:54] Igarashi
    The smoke ducts aren't connected to the
    material storage on the first floor.
[12:58] Shun
    But the fact that it's being
    blown out of the ducts
[13:02] Shun
    means that the powder is being
    sucked in somewhere, right?
[13:10] Yamagami

[13:16] Yamagami
    As sparks from the fire are getting sucked

    the powder may be igniting
     somewhere in the ducts.

    There is a chance of a dust explosion.

    Pull back until we know it's safe again.

    Shun.
[13:53] Shun
    Oxygen tank pressure is at 17 MPa.
[13:55] Shun
    Twelve more minutes of use.
[14:00] Shun
    This must mean someone is inside!

    Shun is probably right about this.
[14:17] Daigo
    There's no time to wait. The two of us will go in.

[15:06] Daigo
    The second floor's ducts
    sucking up the powder
[15:09] Daigo
    despite not being connected to the
    first floor material storage suggests...
[15:14] Daigo
    that someone has taken some and
    unsealed it on the second floor.
[15:19] Daigo
    This... is maybe...
[15:27] Igarashi
    Captain Yamagami.
[15:29] Igarashi
    The fire is refusing to extinguish.
[15:31] Igarashi
    It really seems like...
[15:35] Daigo
    ...this might be a case of arson!
[15:37] Shun
    Is anybody here?
[15:39] Shun
    Anyone?
[15:41] Daigo
    I was already thinking something was off
    with the emergency door not opening.
[15:45] Daigo
    They took this step to prevent the pump squad
[15:47] Daigo
    from getting in until the
    dust explosion happened.
[15:50] Daigo
    If that is the case,
[15:51] Daigo
    it would explain why we couldn't
    find them during our sweep.
[15:54] Daigo
    They were hiding.
[15:56] Igarashi
    But if that were the case,
[15:59] Igarashi
    they must have escaped by now.
[16:01] Daigo
    No, the color of the smoke changing from the
    powder inside it only started just now,
[16:05] Daigo
    which means they are still in the facility!
[16:08] Daigo
    For whatever reason,
    they have remained on site!
[16:16] Shun
    Is anybody there?
[16:19] Shun
    Damn it.
[16:21] Shun
    Where are they?
[16:22] Daigo
    I believe Shun realized this,
[16:25] Daigo
    but didn't have the leeway to
    explain before rushing in!
[16:29] Amakasu
    Onoda Shun has sharp instincts. Good.
[16:34] Amakasu
    And Daigo is astute.
[16:38] Amakasu
    He understood his buddy immediately.
[16:44] Amakasu
    Way faster than I did...
[16:51] Daigo
    How's it look, Shun?
[16:52] Daigo
    Do you see them?

[17:33] Yamagami
    We've got a 252, adult male, level 300.
[17:36] Igarashi
    Bring the rescue squad around to
    the east-side emergency exit.
[17:40] Usui
    Yes, sir!
[17:43] Yamagami(m)
    It's gotten to the point where
    the sparks are visible now...
[17:47] Yamagami
    A dust explosion could occur at any moment!
[17:51] Daigo(M)
    What the...
[17:53] Daigo(M)
    What are those claw-marks on his neck?
[17:58] Daigo(M)
    The smoke ducts are functioning...
[18:00] Daigo(M)
    He shouldn't have breathed
    in that much smoke.
[18:07] Daigo
    252 has regained consciousness!
[18:09] Daigo
    Breathing has also resumed!
[18:12] Daigo
    We're bringing him out!
[18:13] Yamagami
    Go towards the east-side emergency exit.
[18:16] Yamagami
    We're coming to help!
[18:17] Yamagami
    Hurry up, Toake! Onoda!
[18:20] Chief
    We have a report that the
    ducts' dampers won't close.
[18:23] Chief
    Closing all the intakes will be difficult,
[18:26] Chief
    so we are considering trying to
    destroy the ducts from the outside.
[18:29] Chief
    Everyone other than 8HR and Fuwa Rescue,
[18:32] Chief
    prepare for the dust explosion and retreat.
[18:35] Daigo
    The east-side emergency
    exit is 20 meters away.
[18:40] Daigo(m)
    Resuscitating him took quite a bit of time.
[18:45] Daigo(m)
    Both the powder concentration and
    ignition potential are too high!
[18:50] Yurie
    According to Assistant Fire
    Sergeant Toake's report,
[18:52] Yurie
    four one-kilo bags of
    powder have been sucked up.
[18:56] Yurie
    Even if they shut down the
    ducts now, it's too late...
[18:59] Mochizuki
    All the conditions are right for an ignition.
[19:03] Yurie(m)
    The only thing they can do is
    destroy the ducts from the outside.
[19:06] Yurie(m)
    But isn't it too late?
[19:09] Amakasu
    This is exact, right?

    Yes, sir.

    Thank you, Fire Lieutenant Sato.

    Going against orders.
[19:35] Amakasu
    Only a handful of geniuses can

    Ten meters to the
    east-side emergency exit.
[20:05] Shun(M)
    Damn, my arms...
[20:07] Shun(M)
    This is because I had to climb up so high.
[20:10] Narrator
    Including their oxygen tanks,
    the equipment weighs 20 kilos.
[20:16] Shun(M)
    But Daigo's got it even worse.
[20:18] Shun(M)
    He was doing chest compressions
    in full gear for several minutes!
[20:24] Daigo
    Shun, we're almost there.
[20:26] Daigo
    Hang on!
[20:30] Igarashi
    Daigo! Shun! Igarashi here.
[20:33] Igarashi
    We've arrived at the
     east-side emergency exit.
[20:35] Igarashi
    We'll come assist!
[20:36] Shun
    No, we're fine.
[20:39] Shun
    It's cramped in here,
    and we can already see the exit!
[20:42] Daigo
    Shun!
[20:43] Shun
    More importantly,
[20:45] Shun
    please stand back, so you don't
    catch any of the blast.
[20:48] Shun
    Just in case.
[20:52] Shun(M)
    I'll protect you from the
    explosion no matter what.
[20:56] Shun(M)
    In exchange, I want you to
    tell me what happened here.
[20:59] Shun(M)
    Are you really... the arsonist?
[21:03] Shun(M)
    Why?!
[21:04] Shun(M)
    Why would you do this?
[21:07] Shun
    You're an idiot, but you still can't die!
[21:11] Shun
    You might have some reason,
[21:15] Shun
    but tell me what it is!
[21:18] Shun
    I'll listen.
[21:23] Igarashi
    Daigo, Shun, hurry!
[21:26] Usui
    There's no time!
[21:27] Shun
    Igarashi-san!
[21:30] Shun
    Please take him.
[21:42] Shun(m)
    Good.
