    This is the inside of a human body.
[00:55] ---
    What is this place?
[01:04] ---
    Nobody's around. What's going on?
[01:11] ---
    I'm so scared!
[01:35] ---
    Th-There it is!

    What is this thing?
[01:42] ---
    Behind me, too!
[01:54] ---
    Somebody help me!
[02:02] ---
    Target sighted!
[02:12] ---
    Hey, are you okay?
SIGN    WHITE BLOOD CELLS (NEUTROPHILS):
    Their main task is to eliminate
    foreign substances from outside,
    such as bacteria and viruses.
    Neutrophils comprise over half
    of the White Blood Cells in the blood.
[02:18] ---
    Thank you very much!
[02:20] ---
    Uh, hey. You're welcome.
[02:23] ---
    By the way, what were you doing
    in a place like this?
[02:28] ---
    Where are you from?
[02:30] ---
    M-My name is Naive T Cell.
[02:33] ---
    I'm an underling with the T Cell battalion,
[02:36] ---
    a-and I'm on patrol.
[02:38] ---
    But there are tons of zombies here.
[02:41] ---
    What kind of place is this exactly?
SIGN    NAIVE T CELL:
    An immature T Cell
    which has never
    encountered an antigen.

[02:51] ---
    I mean, how'd you come through the wall?
[02:54] ---
    It's called "migration."
SIGN    MIGRATION
    To move freely through the system.
[02:57] ---
    These guys are just former common cells.
[03:01] ---
    The thing is,
[03:02] ---
    it seems like they got infected.
[04:42] ---
    EPISODE 3:
    INFLUENZA
[04:45] ---
    Influenza.
[04:48] ---
    They've been infected by a virus.
[04:51] ---
    A virus?
[04:52] ---
    Right.
[04:53] ---
    An influenza virus.
SIGN    INFLUENZA VIRUS:
    A virus that can trigger influenza,
    an infectious disease.
    Falls into three main categories,
    A, B and C. Causes symptoms
    such as fevers over 100 degrees,

[05:05] ---
    Causes symptoms
    such as fevers over 100 degrees,

[05:08] ---
    headaches, joint pain and muscle cramping.
SIGN    When an influenza strain
    that never infected humans
    mutates to the point
    that it does infect them,
    it is called a "new influenza strain."
[05:13] ---
    See, they bind to the bodies of cells
    and then multiply.
[05:17] ---
    Our only hope is to kill them
    before their numbers swell any further!
[05:20] ---
    You're my backup!
[05:23] ---
    Huh?
[05:24] ---
    Hey!
[05:26] ---
    No way can I do that!
    I can't take on a virus!
[05:29] ---
    H-Hey! Listen, you!
[05:31] ---
    You're a T Cell soldier, aren't you?
[05:33] ---
    I'll stay put right here so that I can
    at least avoid getting in your way!
[05:38] ---
    Give a guy a hand, will you?
[05:40] ---
    Look, they're starting to gather
    because we're here!
[05:42] ---
    Can't do it! Too scary!
[05:47] ---
    My, my...

[05:51] ---
    Is everything all right here?
[05:53] ---
    I can see that the virus people
    have multiplied significantly.
[05:58] ---
    A hatchet?
[05:59] ---
    Now then, time to get to work!
[06:06] ---
    W-Watch out!
SIGN    MACROPHAGE'S DEADLY FORCE:
    Significantly potent.
[06:23] ---
    Rest assured.

[06:28] ---
    Let's see, this is...
[06:31] ---
    A Type B virus.
[06:34] ---
    This is Macrophage.
[06:36] ---
    It appears that a Type B influenza virus
    has invaded this body.
[06:40] ---
    Right!
[06:41] ---
    Understood! Please give it your all!
[06:44] ---
    Right! Goodbye!
[06:46] ---
    Helper T Commander,
[06:48] ---
    that was Macrophage
    presenting antigen information.
[06:51] ---
    Very well.
[06:59] ---
    We've just received word
    that a Type B virus has invaded this body.

[07:01] ---
    Yes, yes. Yes, that's correct.
[07:03] ---
    The Killer T Cells will start
    aggregating immediately!
[07:07] ---
    I've notified each organ
    through Dendritic Cell,
[07:11] ---
    so the Killer T Cells
    will soon be here to assist you.
[07:14] ---
    Hey, that's great news.
[07:16] ---
    The Killer T Cells?
[07:18] ---
    U-Um, White Blood Cell, Macrophage,
[07:22] ---
    I'm sorry!
[07:24] ---
    Could you please tell them
[07:25] ---
    I brought down
    just one of these zombies?
[07:29] ---
    Why do you want us to do that?
[07:31] ---
    B-Because if you don't, I...
[07:34] ---

    Hey, so you're here, too.
[07:56] ---
    Yeah.
[08:01] ---
    Hey, Naive!
[08:03] ---
    You let someone else
    do your work for you again, huh?
[08:06] ---
    When are you gonna learn
    to pull your own weight?
[08:09] ---
    And you call yourself a T Cell like us?
[08:12] ---
    S-S-S-S-S-Sorry! I'm so sorry!
[08:15] ---
    I see. So the senpais
    like to bust his chops, huh?
[08:18] ---
    Yoo-hoo! We're here as backup.
[08:21] ---
    Hey, there's still
    a whole horde of them over there!
[08:24] ---
    Let's see you slaughter at least one of them
    this time, ya hear me, you little punk?
[08:27] ---
    Got that?
[08:29] ---
    C'mon, dammit!
[08:31] ---
    Could you give me a yank?

[08:48] ---
    compared to bacteria, the influenza virus's
    proliferation speed is on a different level!
[08:53] ---
    Right, Memory T Cell!
[08:55] ---

[09:33] ---
    Hey, you!
[09:34] ---
    What are you doing, spacing out like that?

    He made a run for it.
[09:44] ---
    Hey, Naive!
[09:45] ---
    Oh my...
[09:48] ---
    Just forget about him!
[09:50] ---
    For now, let's deal with the virus!
[09:51] ---
    Right!
[09:56] ---
    Did something happen?
[09:57] ---
    Run!
[09:58] ---
    U-Um, excuse me!
[09:59] ---
    Is something going on?
[10:01] ---
    There's been a report
    about a viral infection up there!
[10:05] ---
    Thank you very much!
[10:06] ---
    Senpai, what should we do?
[10:09] ---
    That's a good question.
[10:22] ---
    I'm...
[10:24] ---
    What's the matter?
[10:26] ---
    Hey, you're a T Cell, right?
[10:29] ---
    Did something happen?
SIGN    DENDRITIC CELLS
    Their role is to present bacteria
    that have invaded the body,
    and fragments of viral infection cells
    as antigens, and to notify
    other immune system cells.
    As their name implies, they feature protrusions.

    and then notify other immune system cells.
[10:43] ---
    Wait, are you struggling in battle?
[10:46] ---
    All right. I'm going to make a call right now.
[10:55] ---
    Th-That's not it!
[10:57] ---
    I ran away from the battle!
[10:59] ---
    No way can I fight
    those scum that terrifying!
[11:02] ---
    I'm... I'm...
[11:06] ---
    I'm just not powerful like White Blood Cell,
    Macrophage or my senpais!
[11:13] ---
    It's better not to have
    a weakling like me around!
[11:26] ---
    That's not true, Naive T Cell.
[11:31] ---
    Chin up, all right?
[11:33] ---
    You're not the only one.
[11:36] ---
    Nobody starts out powerful, you know.

    Keep up the good work...
    Failure leads to...
    Get well soon!
[12:11] ---
    That's right.
[12:12] ---
    Long ago, your senpais were just like you.
[12:17] ---
    They were all Naive T Cells, too.
[12:22] ---
    They're crying. Just like me!
[12:27] ---
    There are tons more where that came from.
[12:29] ---
    Here!
[12:30] ---
    I'm getting goosebumps for some reason!
[12:33] ---
    Hey, what's wrong?
    Did you get infected by the virus?
[12:35] ---
    Like that would ever happen.
[12:37] ---
    It feels like the dark past
    that we sealed away has been released!
[12:40] ---
    Those kinds of chills!
[12:43] ---
    The reason your senpais give you
    such a hard time
[12:46] ---
    might be because they see
    their past selves in you, don't you think?
[12:52] ---
    Hey, Naive!
[12:54] ---
    When are you gonna learn
    to pull your own weight?

[12:57] ---
    Let's see you slaughter at least one of them
    this time, ya hear me, you little punk? Got that?

[13:01] ---
    C'mon, dammit! This way!
[13:02] ---

    We're all here for you.
[13:17] ---
    All here for me!
[13:20] ---
    White Blood Cell goes on patrol
    to spot the enemy.
[13:23] ---
    Macrophage relays information
    on the enemy.
[13:27] ---
    Because of that, Helper T Commander
    is able to issue commands,
[13:32] ---
    and the Killer T Cells
    can then bring the enemy down.
[13:36] ---
    See? You have all these friends working
    with you, taking pride in their work!
[13:43] ---
    So you know what it is
    you have to do, don't you?
[13:52] ---

[15:52] ---
    There's just no end to these guys!
[16:14] ---
    Everybody...
[16:16] ---
    I apologize for behaving
    in such an unsightly manner earlier.
[16:24] ---
    But I've overcome

[16:47] ---
    Hey! So he finally did it! Freakin' Naive!
[16:51] ---
    This gives us
    Herculean strength, huh? Literally!
[16:54] ---
    No. Isn't this scary?
[16:56] ---
    Hey, I'm here, too!

    Take that!
[18:54] ---
    ...a week later, the influenza virus...
[19:04] ---
    ...had vanished from this body.
[19:18] ---
    You did it!

[20:04] ---
    What a fool.
[20:05] ---
    After tens of thousands
    of his friends just got eradicated...
[20:09] ---
    I'll just annihilate him with one blow,
    so he won't suffer at least!
[20:13] ---
    Wow, he's Mr. Aggressive now.
[20:34] ---
    Take that!
[20:37] ---
    H-Huh?
