**[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

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!

**[03:24] Itou**
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.
***SIGN*** Celebration

**[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.

**[05:45] Daigo**
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.
**[06:58] Nagata**
What?
**[07:00] Yamagami**
Excuse me.

Thank you for your cooperation.
**[07:49] Igarashi**
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...

These are your orders.
**[08:45] Chief**
Fuwa Rescue is to cooperate
with Komai Company
**[08:48] Chief**
and enter from the
second floor's west entrance.
**[08:52] Chief**
Your are to suppress the fire and conduct
search and rescue on the second floor.
**[09:00] Igarashi**
Opening door!
**[09:06] Igarashi**
Four 252s secured.
**[09:09] Shun**
Is there anybody else inside?
**[09:14] Shun(m)**
*This is an emergency door.*
**[09:16] Shun(m)**
*Why didn't it open?*

**[09:21] Igarashi**
The fire started on the west
side of the second floor,
**[09:23] Igarashi**
close to the rotary press.
**[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
check each press one by one.
**[09:48] All**
Yes, sir!

**[10:16] Yurie**
Wait... isn't that...
**[10:31] Yamagami**
Completed sweep of the
second floor for survivors!
**[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*

**[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.
**[12:11] Igarashi**
There may be some kind of
special material fueling it.

**[12:28] Shun**
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?
**[12:50] Usui**
But... I mean...
***SIGN*** 2F Smoke Duct
**[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**
Fuwa Rescue captain to Mission HQ.
**[13:12] Yamagami**
We have spotted powder in the
smoke coming from the ducts.
***SIGN*** 2F Smoke Ducts / Dust Collection Duct Cross Section

**[13:16] Yamagami**
As sparks from the fire are getting sucked
into the ducts along with the smoke,
**[13:20] Yamagami**
the powder may be igniting
somewhere in the ducts.
**[13:30] Chief**
*Urgent, urgent!*
**[13:32] Chief**
*Mission HQ to all squads.*
**[13:33] Chief**
*There is a chance of a dust explosion.*
**[13:36] Chief**
*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!
**[14:06] Yamagami**
Onoda!
**[14:14] Daigo**
Shun is probably right about this.
**[14:17] Daigo**
There's no time to wait. The two of us will go in.
**[14:22] Igarashi**
Daigo!
**[14:22] Igarashi**

Fuwa Rescue is going in again?

**[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.*

**[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!*

*What are those claw-marks on his neck?*
**[17:58] Daigo(M)**
*The smoke ducts are functioning...*

**[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?

**[19:24] Amakasu**
Go.
**[19:27] Amakasu**
Thank you, Fire Lieutenant Sato.
**[19:33] Amakasu**

*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.*
