[00:05] ---
    We may all be different, but we're all here
    to protect this body and to carry out our tasks.
[00:12] ---
    What we need to do as the ones left behind
[00:15] ---
    is to keep this body going. The body
    that our dear friends risked their lives to protect.
[00:21] ---
    Not destroy it.
[00:23] ---
    WHITE BLOOD CELL
[00:43] ---
    ENUCLEATION CEREMONY
[00:52] ---
    The tricuspid valve is about to open.
    Red Blood Cells, please do not stop.

[00:56] ---
    Keep the line moving.
[01:01] ---
    And I just got back from a full round
    around the whole body.
[01:05] ---
    Why do we even bother punching in?
[01:08] ---
    Not like the higher-ups take a good look
    at our timesheets.
[01:10] ---
    You said it.
[01:12] ---
    We don't get paid time off
    or even makeup days.
[01:15] ---
    The only rest we'll ever get is right here.
[01:19] ---
    When the heart comes to a stop.
[01:23] ---
    The heart.
[01:24] ---
    A keystone organ that serves
    as the engine for blood circulation.

[01:28] ---
    A muscular organ, it constricts
    to function as the body's circulatory pump.

[01:38] ---
    Still, the blood vessels seem to be
    in even worse shape these days.
[01:42] ---
    It's a chore just to transport this oxygen.
[01:46] ---
    The pathway's beyond bumpy for sure!
[01:49] ---
    By the way, where's that rookie
    you were always with?
[01:52] ---
    You know, the one with the glasses...
[01:54] ---
    I haven't been able
    to get in touch with him for a while.
[01:56] ---
    His chances of making it back
    aren't looking too good.
[01:59] ---
    Well, I can't say I blame him for wanting
    to bail on an environment like this.
[02:04] ---
    He did show a lot of promise, though.
[02:08] ---
    Winner of the Top Rookie Award no less.
[02:10] ---
    Don't just stand there!
[02:12] ---
    Can't you see we're backed up here? Move it!
[02:14] ---
    S-Sorry!
[02:18] ---
    Even training an incompetent rookie
    is such a chore.
[02:27] ---
    You...
[02:29] ---
    Um...
[02:33] ---
    I'm so sorry!
[02:41] ---
    Man, you really had me worried!
[02:45] ---
    Been waiting for you, rookie!
[02:47] ---
    No...
[02:48] ---
    You're a full-fledged
    Red Blood Cell now, aren't you?
[02:56] ---
    Yes!
[02:57] ---
    Hey! Senpai! Good work!
[03:00] ---
    I was worried about you,
    since I haven't seen you at all lately!
[03:03] ---
    Is that right? Sorry.
    I'm fine now, okay?
[03:07] ---
    Please show me how things are done, all right?
[03:09] ---
    I'm counting on you.
[03:11] ---
    Right!
[04:47] ---
    EPISODE 12:
    RETURN, THE HEART, AND DEMISE
[04:51] ---
    Hey, look how fast you are now.
    Good pace!
[04:54] ---
    Thank you very much!
[04:56] ---
    Whoa...
[04:57] ---
    There's construction going on everywhere!
[04:59] ---
    PLATELETS
[05:00] ---
    Please watch your step.
[05:03] ---
    Thanks for your hard work.
[05:05] ---
    Jeez, could it be any harder to get through?
[05:08] ---
    Do you even need to do
    this kind of construction work?
[05:10] ---
    We apologize for the inconvenience.
[05:13] ---
    The whole body isn't getting enough oxygen
    as it is, so try not to slow us down!
[05:18] ---
    We're sorry.
[05:20] ---
    No need to apologize!
[05:22] ---
    Since we're only doing what needs to be done!
[05:24] ---
    Huh?
[05:25] ---
    Haven't you seen enough of it yourself?
    Clumps of cholesterol, plaque...
[05:32] ---
    Plaque.
[05:34] ---
    Bump-like piles of built-up
    cholesterol and fat.

[05:39] ---
    Differs from dental plaque,
    the plaque that builds up inside the mouth.

[05:43] ---
    Those things are breaking off
    all over the blood vessels!
[05:47] ---
    And fixing all that is our job!
[05:51] ---
    Even still, all this construction work
    everywhere we go is a huge pain for us!
[05:56] ---
    Can't you be more efficient?
[05:57] ---
    Oh, so we should just forget
    about the whole thing? Huh?
[06:00] ---
    Why don't you guys deliver that oxygen
    more efficiently for heaven's sake?
[06:04] ---
    Pretty tense, huh?
[06:06] ---
    Neither of them is really wrong, but still...
[06:10] ---
    Where to next?
[06:11] ---
    Uh...
[06:13] ---
    The next delivery's going to the stomach.
[06:17] ---
    Is something wrong?
[06:19] ---
    Uh, no.
[06:21] ---
    The path to the stomach's pretty clogged, too, so...
    Let's be careful on this delivery.
[06:25] ---
    Right!
[06:34] ---
    MUCUS
[06:38] ---
    It's so hot!
[06:39] ---
    This is my first time here, but who knew
    the stomach was such a harsh place?
[06:43] ---
    It seems to be in better shape
    than the last time I was here.
[07:03] ---
    Senpai? Are you okay?
[07:07] ---
    I'm okay. Let's go.
[07:12] ---
    Hey! You Red Blood Cells there!
[07:14] ---
    Get a move on!
[07:16] ---
    Bring that oxygen here!
[07:22] ---
    Enough already! Didn't I tell you?
[07:24] ---
    This kind of thing happens on a daily basis here!
[07:27] ---
    You can't get sentimental every single time,
    or you'll end up putting the others at risk!

[07:32] ---
    Oh right! That guy...
[07:35] ---
    Gastric Chief Cell!
[07:37] ---
    Nice to meet you! I'm NC8429!
    I look forward to working with you!
[07:42] ---
    Huh?
[07:43] ---
    Uh, I wouldn't...
[07:44] ---
    Who the cell has time to remember names?
[07:47] ---
    Forget that and just get to work!
[07:51] ---
    STOMACH
[07:51] ---
    W-We're sorry!
[07:53] ---
    Come on, let's deliver this oxygen.
[07:54] ---
    R-Right.
[07:59] ---
    The same thing happened to me, too,
    my first time here.
[08:02] ---
    You watched that orientation video, right?
[08:05] ---
    That's right!
[08:07] ---
    When you come to the stomach
    to make deliveries, tell us your names.

[08:11] ---
    It's a lot more pleasant to work
    with a familiar face

[08:13] ---
    than with someone
    you don't even know by name.

[08:17] ---
    We'll be waiting for you guys!
[08:20] ---
    See, that video's really, really old.
[08:23] ---
    Is that right?
[08:24] ---
    We should let them know
    that they need to make a new one.
[08:27] ---
    Hey, you there!
    Quit jawin' and get to work!
[08:30] ---
    Deliver that oxygen!
[08:31] ---
    Sorry.
[08:34] ---
    You work hard now, AA2153.
[08:38] ---
    Right.
[08:40] ---
    Huh?
[08:42] ---
    Good for you for making it back.
[08:45] ---
    Right!
[08:47] ---
    That's amazing! He remembers
    your name, huh, Senpai?
[08:55] ---
    The truth is, I still didn't know...
[08:59] ---
    We've come to deliver your oxygen!
[09:01] ---
    Oh, thanks for your hard work.
[09:04] ---
    ...what it truly meant to work.
[09:08] ---
    Here's your oxygen!
[09:10] ---
    You work so hard every day.
[09:12] ---
    No.
[09:13] ---
    But...
[09:15] ---
    Since this is...
[09:17] ---
    my job!
[09:21] ---
    Excuse me!
[09:24] ---
    I'm going to try...
[09:27] ---
    to give it my all one more time.
[09:35] ---
    All right, we've spotted the germs!
[09:38] ---
    Let's get this over with fast.
[09:40] ---
    Since we need to make up
    for our blunder during the gout battle.
[09:43] ---
    Don't let your guard down.
[09:45] ---
    - Copy that!
    - Copy that!
[09:50] ---
    Hey, this is a breeze!
[09:54] ---
    Look out!
[10:00] ---
    That was close!
[10:02] ---
    Watch your back.
    The shape this body's in...
[10:06] ---
    Germs aren't the only enemy now.
[10:10] ---
    What's up with this place?
[10:12] ---
    It's bursting with plaque!
[10:14] ---
    It's getting worse and worse, huh?
[10:17] ---
    Watch your step, okay?
    We'll have to transport them one by one.
[10:21] ---
    Okay.
[10:25] ---
    Finally made it through.
[10:28] ---
    But still...
[10:31] ---
    for the coronary arteries,
    which carry blood to the heart,
[10:33] ---
    to end up like this...
[10:35] ---
    This is no joke.
[10:37] ---
    RIGHT ATRIUM, RIGHT CORONARY ARTERY,
    AORTA, LEFT ATRIUM,
    LEFT CORONARY ARTERY,
    RIGHT VENTRICLE, LEFT VENTRICLE
[10:38] ---
    The coronary arteries.
[10:40] ---
    Wrapped around the entire heart,
[10:42] ---
    these arteries supply oxygen and nutrients
    to the heart muscle.

[10:47] ---
    About 5% of the total blood volume in the body
    flows through these vessels.

[10:48] ---
    RIGHT CORONARY ARTERY
[10:48] ---
    LEFT CORONARY ARTERY
[10:56] ---
    If this path is obstructed...
[10:59] ---
    What would happen?
[11:00] ---
    We wouldn't be able to reach the heart,
[11:03] ---
    and we wouldn't be able to deliver
    any oxygen or nutrients, either.
[11:06] ---
    What? Doesn't that mean that...
[11:11] ---
    It won't do any good to think about it.
[11:13] ---
    Right now, let's just do what we can.
[11:24] ---
    Did someone drop this?
[11:38] ---
    Wh-What's going on?
[11:40] ---
    Hey, you guys...
[11:43] ---
    What in the world happened?
[11:44] ---
    The plaque ruptured.
[11:46] ---
    The plaque?
[11:47] ---
    The Platelets are forming a clot now...
[11:50] ---
    but as you can see,
[11:52] ---
    the pathway's so narrow now,
    it's turning into a traffic jam.
[11:55] ---
    Is this...
[11:56] ---
    a blood clot?
[11:59] ---
    Blood Clot.
[12:01] ---
    Blood that clumps inside the blood vessels.
[12:04] ---
    Formed when the vessel walls
    are injured or inflamed.

[12:09] ---
    As they block blood flow,
    they can lead to all kinds of diseases.

[12:15] ---
    It's just like that pulmonary embolism.
[12:23] ---
    Hey, you there!
[12:24] ---
    Y-Yes?
[12:26] ---
    Don't get any closer!
    Do you want to end up like that?
[12:30] ---
    I-I'm sorry!
[12:32] ---
    We'll be careful as we move on.
[12:34] ---
    W-We're moving on?
    Through a place like this?
[12:37] ---
    It'll be all right. Just follow me.
[12:45] ---
    How are the coronary artery
    plaque ruptures looking?
[12:48] ---
    The Platelets are repairing them now,
[12:52] ---
    but the vessels have narrowed,
    so now the blood pressure is rising.
[12:56] ---
    What?
[12:57] ---
    We're seeing signs of angina.
[13:00] ---
    Looks like there's just enough room
    for the Red Blood Cells to pass through, but...
[13:04] ---
    So, we've managed to avoid
    the worst case scenario, but...
[13:09] ---
    this means that there's still the risk
    of a secondary disaster.
[13:14] ---
    It looks like we can just make it through.
[13:16] ---
    Yeah. Let's keep going
    and get this oxygen to the heart.
[13:23] ---
    It's gonna go! Make a run for it!
[13:27] ---
    This way!
[13:37] ---
    N-No...
[13:42] ---
    A-Are you all right?
[13:44] ---
    Come on, give me a hand!
[13:45] ---
    R-Right!
[13:52] ---
    No good. It's not budging.
[13:56] ---
    Are you kidding me?
    The space to get through...
[14:00] ---
    It's completely gone!
[14:04] ---
    Who would've thought?
[14:06] ---
    To think that the coronary arteries
    could get completely clogged like this...
[14:10] ---
    These symptoms...
[14:12] ---
    This is a heart attack!
[14:17] ---
    Who would've thought?
[14:19] ---
    To think that the coronary arteries
    could get completely clogged like this...
[14:23] ---
    These symptoms...
[14:25] ---
    This is a heart attack!
[14:28] ---
    Heart attack.
[14:31] ---
    A disease that occurs when a blood clot forms in
    the coronary arteries, obstructing the blood supply

[14:36] ---
    and destroying the heart muscle.
[14:39] ---
    Symptoms include prolonged,
    severe pain in the front of the chest,

[14:44] ---
    difficulty in breathing,
    arrhythmia, cyanosis and shock.

[14:52] ---
    At this rate, no oxygen will reach the heart,
    and it will become necrotic!
[14:59] ---
    S-Senpai, what should we do?
[15:06] ---
    Senpai?
[15:08] ---
    Grab as much of that oxygen as you can.
[15:10] ---
    What?
[15:11] ---
    Hurry!
[15:12] ---
    O-Okay!
[15:15] ---
    We have to get there! To the heart!
[15:18] ---
    If we don't make it,
    the heart's gonna stop!

[15:21] ---
    This body will...
[15:23] ---
    This body will be done!
[15:31] ---
    CELL
[15:31] ---
    Wh-What the...
    Something's going on here!
[15:34] ---
    Damn!
[15:36] ---
    What in the world...
[15:38] ---
    What in the world is happening?
[15:42] ---
    So, the time has come at last, huh?
[15:46] ---
    Actually, I'm surprised it held out this long.
[15:50] ---
    And now,
[15:52] ---
    we'll have to perform our final task.
[16:00] ---
    Oh no! The oxygen's about to run out!
[16:03] ---
    At this rate, the heart will...
    We have to do something now!
[16:10] ---
    Ah, ah...
[16:13] ---
    All cells in this body, can you hear me?
[16:16] ---
    We will now hold
    an emergency meeting for all cells.

[16:21] ---
    Emergency meeting?
[16:23] ---
    This is a first for me, too.
[16:28] ---
    All of you cells...
[16:32] ---
    You've done a good job until now,
    working for this body.

[16:38] ---
    However...
[16:40] ---
    there is no need for you to carry on.
[16:44] ---
    Huh?
[16:46] ---
    What does he mean,
    "there's no need for us to work"?
[16:52] ---
    Just now, a serious incident occurred
    within the coronary arteries.
[16:57] ---
    At this time, the oxygen supply
    to the heart has been halted.

[17:03] ---
    H-Hey! Hold on a second!
[17:05] ---
    What's going to happen to this body
    if the heart stops?
[17:09] ---
    Smoking and drinking to excess...
[17:11] ---
    Hot!
[17:12] ---
    Increased cholesterol levels and stress...
[17:18] ---
    These factors have led to the numerous threats
    this body has been exposed to until now.

[17:25] ---
    Liver dysfunction, gonococci, spot balding,
    kidney stones, urinary tract infection...

[17:34] ---
    pulmonary embolism, H. pylori...
[17:37] ---
    And each time, thanks to your work,
    we've managed to overcome those threats.

[17:43] ---
    But this is the final straw.
[17:46] ---
    As of today, this body will meet its demise!
[17:52] ---
    Demise?
[17:54] ---
    This is the end?
[17:56] ---
    All of a sudden?
[17:57] ---
    You really think you can give a speech
    like that and we'll just eat it?
[18:01] ---
    Give us a real explanation!
[18:04] ---
    O-Of course, we'd anticipate the possibility
    of something like this happening eventually.

[18:09] ---
    But it's not as if we were concealing it from you.
[18:13] ---
    There was a good chance that it could've been
    averted had the situation improved.
[18:20] ---
    Liar!
[18:22] ---
    Don't give us that!
[18:24] ---
    If you knew all along, wasn't there something
    you could've done about it?
[18:28] ---
    We've taken every possible action on our end...
[18:32] ---
    but, uh, this body is now
    in an extremely harsh environment.

[18:38] ---
    You run us all into the ground,
    and now you're dumping that on us?
[18:40] ---
    Is that irresponsible or what?
[18:44] ---
    Truly...
[18:46] ---
    We are truly sorry!
[18:58] ---
    All of you,
[18:59] ---
    thank you for all your hard work until today.
[19:03] ---
    Where are you going?
[19:10] ---
    The heart...
[19:12] ---
    It stopped?
[19:14] ---
    Oxygen... Is there any oxygen anywhere?
[19:18] ---
    You can search all you want,
    but you won't find any.
[19:20] ---
    What about the coronary arteries?
    Can't we pass through the coronary arteries yet?
[19:25] ---
    Not happening. They're still clogged up,
    and there's nothing we can do.
[19:30] ---
    Dammit!
[19:32] ---
    Senpai?
[19:33] ---
    As of today...
[19:35] ---
    you won't have to work anymore.
[19:38] ---
    And as for us,
    we will take responsibility and...

[19:46] ---
    What are we supposed to do?
[19:47] ---
    How should I know?
[19:51] ---
    Calm down!
[19:52] ---
    Everyone, carry out your respective roles!
[19:59] ---
    Th-The body's functions...
[20:02] ---
    are coming to a halt!
[20:05] ---
    There has to be some oxygen!
    There has to be some somewhere!

[20:09] ---
    WELCOME TO THE LUNGS
[20:10] ---
    W-We're not getting any oxygen!
[20:13] ---
    H-Has the breathing stopped?
[20:21] ---
    It's all right. It's going to be all right.
[20:23] ---
    So, everyone, calm down.
[20:34] ---
    Dammit!
[20:35] ---
    Digestion's stopped cold!
[20:42] ---
    Um, your next order, sir...
[20:47] ---
    We're waiting for your instructions, sir.
[20:50] ---
    There's nothing more we can do.
[21:12] ---
    It's the end of the world!
[21:17] ---
    Now we can finally rest.
[21:20] ---
    We don't have to work anymore.
[21:23] ---
    But that's so...
[21:25] ---
    irresponsible!
[21:27] ---
    Telling us to work one second,
    then telling us not to work the next!

[21:31] ---
    Work...
[21:32] ---
    Please work, heart!
[21:39] ---
    I...
[21:41] ---
    I still...
[21:45] ---
    s-still...
