Lunch time!
I'm so hungry, I could die!
Hey, let's go eat in the courtyard.
A picnic, eh? Count me in!
We should ask Yokko to come along.
Time to stop by Class 1, then.
Girls tend to form groups for whatever reason.
I'm so hungry.
And I get extremely nervous at times like these.
Which club are you gonna join?
Dunno. Still thinking about it.
Looking for one that's really chill.
Chill? What the heck?
Talk about lazy.
All right.
Seriously? My sides!
That's just nope, right?
Yeah, nope. Not happening.
Yeah, not happening.
Whatever.
I'm fine by myself.
Yeah, right.
Do I really feel that way?
In truth...
Amanchu!
"The Story of the Secret to Excitement and Happiness"
I'm really grateful to you, Kohinata-san.
You're making such a big deal of it.
No, it really did make me happy
when you asked me to walk home with you
back there at the parking lot.
And during lunch, too...
Look, Teko!
I managed to grab some chocolate croissants!
Let's eat together!
Sure.
Coming from Tokyo to a school in an unfamiliar town
has left me nervous.
Oh! You're from Tokyo?
Yeah.
Whoop!
Oh, but I don't mean to say I'd rather be in Tokyo.
Uh-huh...
Izu has really fresh air and water,
and there's such a huge ocean.
But still...
I'm finding it impossible
to fix my cowardly nature.
Oh, no! I've just been going on and on!
Sorry, Kohinata-san.
Don't worry about it.
I love listening to people talk,
so no worries!
It's so strange.
I usually never talk about myself this much.
You must be a good listener.
Huh? You think?
Actually, I'm not very good at talking to people.
But you introduced yourself to the class so confidently.
Like, even when I want to express something, I can't put it into words...
And, because I can't use my words,
I end up overdoing it with my actions.
Like, uh...
Er...
Sorry! I can't explain it very well.
Is that whistle part of it, too?
Yeah.
It comes in handy.
So, you're filled with anxiety every day?
Y-Yeah...
I see.
Cha.
Wh-What?
What's the matter, Kohinata-san?
Cha... Cha!
Where are you going?
The bus stop's over there...
I'm letting Kohinata-san lead me around by the nose again.
Kohinata-san?
Wh-What's the matter?
Are you all right?
It starts tomorrow, right?
The trial period for clubs. What do you do in a trial?
There must be seniors.
I hope they're not scary.
I wonder if I can fit in...
O-Okay...
Uh, I have no idea what you're saying...
You know...
My grandma says that
those who are miserable living in the moment will find misery anytime, anywhere.
It's a tunnel of sakura!
You just moved here,
so I figured you wouldn't know this place.
Yeah...
What do you think?
It's so pretty.
Thank goodness.
I'm happy I got to come here and see the sakura with you.
Happy?
Oh, I'm the same.
I feel really happy right now.
Oh?
Then you'll be fine.
My grandma also says that
those who are happy living in the moment will find happiness anytime, anywhere!
Grandma's always right,
and her pork soup is the best in the world.
And, well...
I'm here with you.
So you'll be fine tomorrow, the day after, and ever after!
She was doing her best to cheer me up, huh?
You know, the sakura isn't the only reason I feel so happy,
Pikari.
Cha, cha, cha!
Amanchu!
One, two!
We're recruiting members!
Why don't you come check it out? It's a fun club.
Diving Club
Whoop!
The day I join the Diving Club is finally here!
Look, Kohinata-san, this is just a trial period.
Let's-a-knock!
Ba-dump
Ba-dump, ba-dump...
Ba-dump, ba-dump!
Come in!
Ba-dump! Ba-dump!
O-Okay!
Oh, perfect timing.
Whoop?
Katori-sensei?
I received a complaint
that there were signs someone sneaked into this room last week.
Does anyone here have any idea who it may have been?
I-I...
I might've gotten a little carried away.
Yeah, we did something we shouldn't have done.
I know!
Go ahead.
That was me!
So it was you!
Whack
S-Sorry. Me, too.
Whack
U-Uh...
I bet she dragged you in.
Whoop!
They get along well, I see.
Sheesh.
Anyway, what business do you two have with the Diving Club?
I'm here to join.
I-I'm here to take part in the trial period.
Um, just the trial period.
Just the trial period. Nothing else.
Glad to have you!
Welcome to the Diving Club!
Wait! Are you the Diving Club's advisor?
Right-o.
What a surprise!
No, it's not.
Didn't you two check the bulletin board?
Hey.
I'd already decided to join the Diving Club, so I didn't bother!
I wasn't going to join any clubs...
You're so flippant, sheesh.
But, Katori-sensei,
isn't the Diving Club's advisor
that guy over there?
Advisor Cha!
Cha.
Uh, Katori-sensei,
will I be diving right away, even if I'm only a trial member?
Cha!
Nah. Before you dive, you need to study for a bit.
Study?
Come on. Don't look so unhappy.
Huh?
I'm kind of disappointed right now.
I'm allergic to the word "study."
Why?
It's vital you learn a few things before you dive.
You're a diver, Pikari, so you should know this.
Whoop...
So Katori-sensei calls her Pikari.
I feel really nervous for some reason.
Consider this...
While taking a skyscraper elevator, or during a flight,
have you ever had a ringing in your ears?
I-I have.
Do you know why that happens?
No.
You see,
it happens when there's a difference
between the air pressure in and out of your body.
Air in the body?
There's a balloon inside your ear!
What a sloppy explanation.
It's not just the ears.
Several places in the human body,
like the lungs and the respiratory tracts, collect air.
When there's a change in atmospheric pressure,
the disparity with the air pressure within your body
compresses your eardrums.
That's what causes the ringing.
Now, apply this principle to underwater conditions.
Water is denser and heavier than air,
so the changes in pressure are far more drastic
than they are on land.
At the depth of ten meters,
where pressure is double that of sea level,
the volume of air within your body gets compressed to half.
At the depth of twenty meters, where pressure is triple that of sea level,
it gets compressed to one-third.
O-One-third?
Depth Pressure Air Volume
A question, then.
Depth Pressure Air Volume
At the depth of forty meters,
the volume of air within your body is down to one-fifth.
What happens to the air pockets then?
O-One-fifth...
They get crushed.
Correct.
They get compressed pretty hard.
Crushed flat!
F-F-Flat?!
Wh-Wh-Wh-Wh-What do we do, then?
Pop?
No weird sound effects! Denied!
Well...
To keep them from getting crushed,
all you need to do is intake plenty of air
and maintain a consistent air volume.
So long as you maintain the usual air volume by breathing,
your lungs and respiratory tracts won't get crushed.
But your ears won't get any air, even if you do breathe,
so you'll have to divert some there yourself.
If you don't, you'll feel severe pain and strain
just by diving one meter.
What comes in handy at such times
is ear equalization.
Ear equalization?
Come help, Pikari.
Sure!
She just called her Pikari again.
Method one:
swallow your saliva.
Method two:
move your jaw left and right.
This one is a little difficult, so it's for advanced divers.
Method three:
pinch your nose and send air to your ears.
This is the recommended method for beginners.
All right, Teko. Try method three.
Teko?
Teko!
O-Oh, right.
I'm Teko.
Uh, right here and now?
Yes.
E-Er...
Come on! Pinch your nose already.
Now close your mouth and blow.
Well?
There was a weird noise.
That's ear equalization.
Very well done.
Whoop!
Cha, cha!
You nailed it, Teko!
Y-Yeah...
Pikari.
Now, taking into account everything we just discussed,
there is a major, ironclad rule to diving.
What could it be?
I don't know.
Don't give up so easily.
Uh...
What?
Major, ironclad rule?
I really don't know...
Here's a hint:
instead of what happens when diving,
think about what happens when you rise to the surface.
Let's say you have the optimum air volume
for the depth of thirty meters.
What will happen to it at the depth of ten meters?
Teko.
Depth Pressure Air Volume
Depth of thirty meters... 4 ata...
The air volume is one-fourth...
Depth of ten meters... 2 ata...
The tightly compressed air
will gradually be released from the pressure...
...and expand to double the volume.
And what will that do to your lungs?
They'll blow.
Then what should you do to prevent that?
Y-You must let the air out of your body.
Correct!
The ironclad rule of diving
is to never stop breathing underwater.
Never stop breathing...
As long as you keep breathing,
the air volume will naturally get adjusted.
Click.
The new school,
the unfamiliar town,
the depressing mornings,
and the path to school that never felt right.
I used to find all of that scary,
but the desire to know more about this unknown world,
and see more of this unseen world, took shape inside of me.
It's almost like a jigsaw puzzle falling into place.
Each piece has a reason,
and every piece has meaning.
How fun is that?
I...
I want to keep...
This is bad, Teko!
Your excitement rubbed off on me!
Diving is fun and interesting, isn't it?
Yeah, it's interesting.
It's really exciting, isn't it?
Yeah, it's exciting.
Makes you wanna hurry up and dive, right?
Yeah, I wanna hurry up and dive.
Let's dive together, Teko!
Sure, Pikari!
You just called my by my nickname for the first time!
You called me Pikari!
E-Er, well...
I'm so happy...
I'm so happy!
The real me was always waiting,
Teko...
Teko!
praying for someone to extend their hand.
Teko!
Cha.
I hated myself for being a coward
who could do nothing but wait.
But even those feelings
became a meaningful piece
that fell perfectly into place to form
the first, pure-white page of my spring album.
Everyone gets worried their first time.
So you just have to hurry up and get it over with.
Next time, on Amanchu!:

I'm so excited...
I'm so excited.
