*I wonder what's wrong.*
**[01:40] ---**
*Since he had had that talk with NK,
things seem kind of tense.*
**[01:40] ---**
CELL
**[01:40] ---**
WHITE BLOOD CELL
**[01:47] ---**
Nyuuu!
**[01:49] ---**
I wonder what's bugging those two.
**[01:52] ---**
Nyuuu?

EPISODE 6:
HARMFUL BACTERIA
**[01:56] ---**
*"Harmful Bacteria."*
**[02:06] ---**
U-Um, excuse me, how much farther?
**[02:09] ---**
Oh, right.
**[02:11] ---**
We're almost there. See?
**[02:17] ---**
This is the large intestine.
**[02:17] ---**
KEEP THE INTESTINE CLEAN
**[02:20] ---**
*The large intestine.*
**[02:22] ---**
*The organ that absorbs water and minerals
and produces feces.*
**[02:26] ---**
*Where the final stage
of digestion is performed.*
**[02:29] ---**
*The large intestine
is about 1.5 meters in length*
**[02:32] ---**
*and can be divided into the cecum,
the colon and the rectum.*
**[02:36] ---**
*It is said that several hundred
different species of bacteria,*
**[02:39] ---**
*totaling one hundred trillion,
inhabit the large intestine.*
**[02:44] ---**
Not looking good.
**[02:45] ---**
It's gone to ruin, all right.
**[02:49] ---**
FRAGILE
CONDENSED GAS
**[02:51] ---**
Let's see.
**[02:54] ---**
White Blood Cell! Ordinary Cell!
**[02:57] ---**
Thank you for your— good work—
I just happened— to be delivering—
**[03:01] ---**
Are you okay?
**[03:04] ---**
I-I can't breathe!
**[03:08] ---**
This is toxic gas from the harmful bacteria
that live in the intestines.
**[03:12] ---**
- "Toxic gas"?
- "Toxic gas"?
**[03:15] ---**
The bacterial balance in the gut must be off,
and the harmful bacteria seem to be predominant.
**[03:22] ---**
This is bound to cause
some harmful effects.
**[03:24] ---**
Is that right?
**[03:25] ---**
What a stink!
**[03:27] ---**
I-I'm going to take care of this delivery right now!
**[03:29] ---**
You be careful, okay?
**[03:32] ---**
Let's see, this delivery's going to...
**[03:36] ---**
WELCOME
PROBIOTICS
IN THE LARGE
INTESTINE
**[03:36] ---**
Everyone, please look this way!
**[03:39] ---**
PLATELETS
**[03:39] ---**
Okay!
**[03:44] ---**
TROLLEY
STOP
**[03:46] ---**
Roughly three types of bacteria
reside in the intestines.
**[03:51] ---**
First, the good bacteria
that are beneficial to the body...
**[03:55] ---**
*Good bacteria.*
**[03:57] ---**
*Lactic acid bacterium, Lactobacillus gasseri,
Lactobacillus bifidus and the like*
**[04:00] ---**
*work to boost immunity
and to stimulate intestinal activity.*
**[04:07] ---**
Next, the scary harmful bacteria
that wreak havoc on the body!
**[04:13] ---**
*Harmful bacteria.*
**[04:15] ---**
*Pathogenic E. coli, Staphylococci,
Clostridium and the like*
**[04:20] ---**
*cause proteins to degrade
and produce toxic by-products.*
**[04:24] ---**
Wasn't that scary?
**[04:26] ---**
Yeah!
**[04:28] ---**
Last but not least,
**[04:29] ---**
Are you okay?
**[04:29] ---**
neither good nor bad...
**[04:31] ---**
Opportunistic pathogens!
**[04:33] ---**
*Opportunistic pathogens.*
**[04:35] ---**
*Bacteroides, non-pathogenic E. coli,
Eubacterium and the like*
**[04:39] ---**
*are all bacteria
which do neither good nor harm.*
**[04:44] ---**
*They ally themselves with whichever bacteria,
good or harmful, has the upper hand.*
**[04:49] ---**
Oh, so cute!
**[04:52] ---**
Look how many of them there are!
**[04:56] ---**
That was fun, wasn't it?
**[04:57] ---**
Do you think
we can come back sometime?
**[04:59] ---**
I hope so!
**[05:03] ---**
Hey there!
**[05:06] ---**
Oh! Big Sister Red Blood Cell!
**[05:09] ---**
Hello, little Platelets!
**[05:11] ---**
Hello!
**[05:12] ---**
Are you touring this area?
**[05:14] ---**
Yes!
**[05:15] ---**
Oh! This way, this way!
**[05:17] ---**
Go on! Take a look!
**[05:18] ---**
It's really cute!
**[05:25] ---**
THEATER ROOM
**[05:27] ---**
The intestines are said to be home
to approximately a hundred trillion bacteria in all.
**[05:33] ---**
The body's health changes whenever
there's a shift in the balance between them.
**[05:38] ---**
Oh really?
**[05:41] ---**
Hey, so his friends are all here?
**[05:44] ---**
Yeah.
**[05:45] ---**
There are up to a hundred trillion bacteria
in the intestines, they say.
**[05:51] ---**
Wow! That many right here?
**[05:54] ---**
Then, we're sure to find them, right?
**[05:56] ---**
Yeah.
**[05:57] ---**
That'll be a relief.
**[05:59] ---**
*He doesn't sound
the least bit relieved.*
**[06:03] ---**
*I wonder what's up with him.*
**[06:05] ---**
Nyuuu! Nyuuu!
**[06:07] ---**
Lactic Acid Bacterium,
it won't be long now.
**[06:09] ---**
There are tons of your friends
right here, all right?
**[06:14] ---**
I bet you have
some awesome powers of your own!
**[06:18] ---**
Nyuuu!
**[06:19] ---**
Hey, you need to pipe down!
**[06:19] ---**
Nyuuu! Nyuuu! Nyuuu!
**[06:21] ---**
Hey! You don't want NK to catch on!
**[06:23] ---**
She's eagle-eyed, you know!
**[06:26] ---**
*It's glaringly obvious, guys.
So ridiculous!*
**[06:29] ---**
Look, you two, I don't care what you do
as long as you're quiet.
**[06:33] ---**
I don't want him to know
we're on the move.
**[06:37] ---**
Attention!
**[06:38] ---**
Squad Leader, please be careful!
**[06:40] ---**
We'll be close behind you
with the antigen presentation signal!
**[06:43] ---**
All right!
**[06:44] ---**
Now, I've fought with him once in the past.
**[06:47] ---**
And I'm going to use that experience today
to head to the front lines as a Memory T Cell
**[06:52] ---**
and finish off the enemy!
**[06:55] ---**
*Memory T Cell.*
**[06:57] ---**
*Some Killer T Cells
turn into Memory T Cells*
**[07:01] ---**
*so that they can be ready to attack
in case the same enemy reappears.*
**[07:07] ---**
I'm sure you'll miss me,
but it's going to be okay!
**[07:09] ---**
I'll still be looking out for you
even as a Memory T!
**[07:14] ---**
Whether or not you'll be
up to the fight after losing me...
**[07:18] ---**
Nothing worries me more
as your squad leader.
**[07:21] ---**
After all, who else but me
has the inside track on his moves...
**[07:23] ---**
and the ability to land the decisive blow...
**[07:24] ---**
The squad leader sure looks thrilled.
**[07:26] ---**
He may be mistaking this for a promotion.
**[07:29] ---**
But I swear on this cap
that I'll fulfill my mission.
**[07:33] ---**
Though there's no guarantee that any of us
will be alive when we meet again.
**[07:37] ---**
So, I'll be waiting for you all in hell!
**[07:41] ---**
Squad Leader!
**[07:44] ---**
Man, you're in my way.
**[07:50] ---**
Squad Leader!
**[07:51] ---**
Killer T!
**[07:52] ---**
Wh-What the...
This abrupt, uncalled for violence is—
**[07:56] ---**
Oh my, I'm really sorry. My foot slipped.
**[08:00] ---**
NK!
**[08:02] ---**
I was wondering what all you passive grunt cells
were doing, milling around here.
**[08:06] ---**
Is it a farewell bash?
Or maybe you're rehearsing for a play?
**[08:10] ---**
How nonchalant!
**[08:12] ---**
I'm not sure you even remember who the enemy is
now that you're so complacent, Memory T Cell.
**[08:18] ---**
NK, what did I ever do to you?
**[08:22] ---**
NK! Stop provoking Killer T
so that he'll regain his confidence!
**[08:26] ---**
Shut up!
**[08:28] ---**
Neutrophil! Did I hear you call me "Killer T"?
**[08:32] ---**
Can't you see this cap of mine?
**[08:34] ---**
It's "Memory T" today!
**[08:37] ---**
- Memory...
- Memory...
**[08:42] ---**
Hey! There you go again, mellowing out
with an ordinary cell!
**[08:46] ---**
Keep that up and you won't even be able
to kill a lowly germ!
**[08:49] ---**
Nyuuu!
**[08:51] ---**
"Nyuuu"?
**[08:52] ---**
Th-That's not true!
**[08:53] ---**
It may seem to be true,
but actually, it's not true at all!
**[08:58] ---**
That's right! It's not true!
I'm a natural-born killing machine!
**[09:02] ---**
And now, I'm off to prepare for battle!
**[09:04] ---**
It's dangerous here,
so you should go somewhere safe!
**[09:06] ---**
Yep, yep!
**[09:08] ---**
Yeah! You'll only get in my way
when I battle that guy!
**[09:11] ---**
Nyuuu!
**[09:11] ---**
NYUUU
**[09:13] ---**
I hear something crying.
**[09:14] ---**
What are these guys, idiots?
**[09:17] ---**
U-Um, I just have a simple question.
**[09:20] ---**
Who's this guy you keep mentioning?
**[09:28] ---**
- A Cancer Cell.
- A Cancer Cell.
**[09:30] ---**
C-Cancer Cell?
**[09:34] ---**
A-A-An enemy like that at large...
I-I-Isn't that dangerous?
**[09:39] ---**
Sure, it's dangerous.
**[09:41] ---**
I've got to head out right away
to crush him. So, Cell boy...
**[09:45] ---**
we'll be going our separate ways now.
**[09:47] ---**
Huh?
**[09:49] ---**
It's time for me to get back to work.
**[09:52] ---**
I'm sorry I can't accompany you to the end.
**[09:58] ---**
Listen. If you go down this road and take a left,
you'll reach the tip of the intestinal epithelium.
**[10:04] ---**
I'm sure you'll come into contact
with Lactic Acid Bacterium's friends there.
**[10:08] ---**
So, return the little guy,
then leave the large intestine
**[10:11] ---**
and make your way
back to the pharynx.
**[10:15] ---**
Okay.
**[10:16] ---**
All right. Keep an eye on your surroundings
and watch your back.
**[10:20] ---**
You can do it, right?
**[10:21] ---**
Yeah.
**[10:22] ---**
Thanks!
**[10:24] ---**
Oh, hold up, White Blood Cell!
**[10:30] ---**
Can you tell me one thing before you go?
**[10:33] ---**
White Blood Cell,
why did you protect us?
**[10:36] ---**
After all...
**[10:39] ---**
you Immune Cells...
**[10:42] ---**
If it's for the sake of the body,
**[10:44] ---**
you kill bacteria and infected cells
who used to be your allies.
**[10:47] ---**
Killing them is your job, isn't it?
**[10:50] ---**
So, how come?
**[10:54] ---**
Nyuuu?
**[10:56] ---**
Huh?
**[10:59] ---**
Right. You're absolutely right.
**[11:02] ---**
It's my job to kill.
**[11:07] ---**
But...
**[11:09] ---**
since all I ever do is kill...
Maybe that's why...
**[11:15] ---**
All right, see you!
**[11:16] ---**
Make sure you send him off right!
**[11:19] ---**
Nyu-nyuuu! Nyu-nyuuu!
Nyu-nyuuu!
**[11:21] ---**
Right!
**[11:28] ---**
This slimy mucin will keep out
any invading bacteria.
**[11:32] ---**
INTESTINAL BARRIER SEEDLINGS
**[11:32] ---**
GOBLET
**[11:32] ---**
Let's get them set up
so they don't get breached.
**[11:42] ---**
That sounds close.
**[11:43] ---**
Yeah.
**[11:44] ---**
We'd better hurry!
**[11:48] ---**
H-Here it comes!
**[11:54] ---**
All right!
The barrier's holding up like a champ!
**[11:58] ---**
You just can't beat mucin for durability.
**[12:01] ---**
That was barely a blip on the radar, huh?
**[12:04] ---**
Hold up!
**[12:07] ---**
- Oh no!
- There's more on the way!
**[12:10] ---**
Let's get out of here!
**[12:17] ---**
This way, this way!
**[12:25] ---**
Sorry!
**[12:29] ---**
There you go!
**[12:30] ---**
Thanks, Big Sister!
**[12:32] ---**
I wanna ride piggyback!
**[12:34] ---**
Me, too!
**[12:35] ---**
Me, too! Piggyback!
**[12:43] ---**
Ouch!
**[12:49] ---**
Um, you see, you see... Um...
**[12:53] ---**
Um...
**[13:00] ---**
Everyone! Big Sister Red Blood Cell doesn't know
what to do, so you all need to line up!
**[13:06] ---**
Okay!
**[13:08] ---**
You're all going to ride?
**[13:11] ---**
Wh-What's that?
**[13:13] ---**
Whoa!
**[13:14] ---**
Excuse me!
That section seems to be broken—
**[13:22] ---**
Is that going to hold up?
**[13:23] ---**
Oh, please don't worry about it.
It happens all the time.
**[13:26] ---**
Whaaat?
**[13:28] ---**
Lately, with the surge in harmful bacteria,
the intestines have been a mess!
**[13:32] ---**
We're totally at our wits' end!
**[13:35] ---**
I-I see that's it's been tough for you all.
**[13:40] ---**
Um, go straight here...
**[13:43] ---**
I hear there are tons of bacteria
on the other side of this wall.
**[13:47] ---**
Nyuuu?
**[13:50] ---**
It's almost time to say goodbye.
**[13:52] ---**
Nyuuu!
**[13:54] ---**
A lot of terrifying things happened,
but it sure was fun, Lactic Acid Bacterium!
**[13:57] ---**
Nyuuu!
**[14:01] ---**
See...
**[14:03] ---**
I never had anyone
to play with when I was a kid,
**[14:06] ---**
and I was bored out of my mind.
**[14:08] ---**
I was really lonely.
**[14:11] ---**
So, meeting you guys...
**[14:14] ---**
and traveling all around the body like this...
**[14:22] ---**
It was such a blast!
**[14:25] ---**
Nyuuu! Nyu-nyuuu!
**[14:27] ---**
Nyuuu! Nyuuu! Nyuuu!
**[14:30] ---**
I told you, it's no use!
**[14:34] ---**
Nyuuu?
**[14:36] ---**
No good!
**[14:37] ---**
The bacteria's attack is too devastating,
and it's only a matter of time before they invade!
**[14:43] ---**
*Goblet Cell.*
**[14:45] ---**
*A mucous-secreting Immune Cell
that produces mucin.*
**[14:49] ---**
*Can also be found in the small intestine
but particularly abundant in the large intestine.*
**[14:54] ---**
Hang in there, Goblet Cell!
**[14:58] ---**
*Intestinal Epithelial Cell.*
**[15:00] ---**
*Absorbs nutrients and water.*
**[15:03] ---**
*Also builds mucous barriers to prevent excessive
immune responses toward Intestinal Cells.*
**[15:11] ---**
Do you know how many billions, trillions
of bacteria there are beyond this wall?
**[15:16] ---**
It looks like they're in trouble.
**[15:18] ---**
Nyuuu?
**[15:19] ---**
Nyuuu!
**[15:21] ---**
We Intestinal Epithelial Cells have to hold them off
with this intestinal barrier!
**[15:25] ---**
Oh man! No way are we
getting there in time now!
**[15:29] ---**
I mean it, it's futile! Come back here!
**[15:33] ---**
- I-I'll help you!
- Don't give up!
**[15:35] ---**
"With burning hearts!
With a solid intestinal barrier!"
**[15:38] ---**
Isn't that our motto? We have to keep
fighting until we reach our limit!
**[15:42] ---**
And I'm telling you, this is our limit!
**[15:47] ---**
Nyuuu! Nyuuu...
**[15:49] ---**
There goes all the mucin
we planted!
**[15:53] ---**
Huh?
**[16:00] ---**
So, this is the other side of the intestinal wall
that we've been striving to reach?
**[16:03] ---**
Now that we're here,
it's nothing special.
**[16:07] ---**
Not a shred of style.
**[16:09] ---**
Who cares? We're going to turn it
into an oasis for us harmful bacteria!
**[16:14] ---**
Toward that end,
**[16:16] ---**
we're going to have to start
by eradicating all of the weeds!
**[16:24] ---**
Come on!
**[16:32] ---**
Wh-What's going on?
**[16:33] ---**
Uh, it looks like
there's some kind of problem.
**[16:36] ---**
It happens all the time!
**[16:38] ---**
H-H-H-Huh?
**[16:40] ---**
These harmful bacteria
sure are troublesome!
**[16:44] ---**
Oh, you guys should all
make a run for it, too!
**[16:46] ---**
Whaaat?
**[16:49] ---**
Are you okay, Platelet?
**[16:51] ---**
Yes! I'm fine!
**[16:53] ---**
- Better get out of here now!
- It seems like we've been invaded by bacteria!
**[16:58] ---**
Everyone! Watch out, okay?
**[17:00] ---**
I can't see in front of me!
**[17:11] ---**
The path's going to narrow
from this point.
**[17:13] ---**
All right, then I'll take the lead.
**[17:17] ---**
Don't ram into me, you klutz.
**[17:23] ---**
I didn't shove you that hard, you know.
**[17:25] ---**
Are you that narrow-minded?
**[17:33] ---**
Damn you! Can you be
more unsteady on your feet?
**[17:35] ---**
Just go the cell home!
You're only going to get in my way!
**[17:37] ---**
Oh, that's rich! Right back atcha!
**[17:39] ---**
You bumped into me first!
**[17:41] ---**
Oh yeah? Well, why are you tagging along,
you miserable loner?
**[17:44] ---**
THUNK
**[17:45] ---**
I'll take being a loner any day!
Better than your band of spineless fools!
**[17:48] ---**
BOOM
**[17:49] ---**
What did you say?
Didn't I tell you to stay away?
**[17:51] ---**
THUMP
**[17:52] ---**
It was my long years of experience and intuition
that led me to determine that he was here!
**[17:54] ---**
RUMBLE
**[17:55] ---**
You're following me!
**[17:56] ---**
WHACK
**[17:57] ---**
Hey, how about not clobbering
each other before the battle?
**[17:57] ---**
STAB
**[17:59] ---**
SMACK
**[18:00] ---**
BANG
**[18:02] ---**
All right! We'll be reaching
the residential area soon!
**[18:05] ---**
It'll be teeming with cells! It might be
unbearable for a social outcast like you!
**[18:09] ---**
Killer T, you might want to stop talking now—
**[18:11] ---**
Huh? "Killer T"?
**[18:13] ---**
Call me "Memory T"! Don't you see this cap?
**[18:16] ---**
All right, fine! Just be quiet!
**[18:18] ---**
There's no telling
where the enemy might be lurking!
**[18:21] ---**
He's right. Are you a moron or what?
**[18:23] ---**
Why are you only telling me off? Not fair!
**[18:27] ---**
Shush!
**[18:31] ---**
It looks like he's meeting us
head-on this time.
**[18:46] ---**
Hey, NK!
**[18:47] ---**
Damn you!
**[18:53] ---**
*Where is he?*
**[19:02] ---**
NK!
**[19:03] ---**
Go!
**[19:08] ---**
You really came back to life just so you could
throw a tantrum, you stupid Cancer Cell?
**[19:12] ---**
Die!
**[19:24] ---**
Did I get him?
**[19:27] ---**
So, you fell for it!
He's nothing but a puppet!
**[19:33] ---**
Look at all the effort
you had to put in against a mere doll.
**[19:36] ---**
Do you know what you've gotten
yourselves into, Immune Cells?
**[19:40] ---**
Where the heck is that voice coming from?
**[20:02] ---**
I'm so thrilled!

**[20:13] ---**
*Cancer Cells.*
**[20:15] ---**

cells in a process called "Infiltration."*
