"Acquaintance arrested for murder of former club hostess"
"Hidetoshi Semba Arrested"
I'm so sorry, Narumi.
It's all my fault.
Don't tell anyone.
Not even your father.
Keep it a secret forever.
Breakfast will be ready soon.
Narumi!
Midsummer's Equation
Hello?
I'm on the train.
No, everything's fine.
Yeah, I'm almost there.
I'm eating it now.
I know.
I'm hanging up now.
You should be minding your manners.
Don't use your phone on the train.
Don't, dear. Sorry.
Turn it off.
My parents will be bombarded with e-mails if I did that.
Telling them that it's been shut down.
That's how kid phones work. - I don't care how they work.
Give me that!
Don't!
That's enough!
Sorry about that...
You won't receive calls now even with the power on.
Aluminum foil blocks cell phone signals.
Problem solved.
We'll be arriving at Harigaura shortly.
Thank you, go ahead.
Wait! Kyohei!
Kyohei, right?
You're so big now! Welcome!
Thank you for having me.
My, you sound so formal.
Are you all right?
Shall I take that? - Thank you.
All this way by yourself. Were you OK?
Yes.
Hi there, Kyohei. You've grown.
Thank you for having me. This is for you.
So well behaved. Unlike two years ago.
You're in fourth grade now.
OK, let's go. Nice cola at home.
Hop in.
"Harigaura Seafloor Mining Explanatory Meeting"
"No to Seafloor Mining!"
We didn't come to hear your one-sided explanation!
You can't destroy the sea of Harigaura!
Quiet please. We'll hold a Q&A session later.
The plan is to mine 50 km offshore at a depth of 800 m...
50 km is right there!
The rare metals could be an essential resource for Japan.
But the local government hasn't approved.
Please be quiet.
Next, the development of the seafloor hydrothermal deposits...
They'll stress the economic effect.
Some think the town will be revitalized.
I'm Nakagawa at DESMEC.
Our plan isn't to start mining right away, but only after -
expert organizations research...
Wait, that's not harmless...
We're trying to explain.
So, uh... For the survey, we'll be using -
manned submersibles, ROVs and AUVs...
Don't dodge the issue! For that survey...
You'll dig the seafloor! - Please listen!
We'll use manned submersibles, ROVs and AUVs to examine...
Here's Dr. Yukawa, associate professor at Teito University.
Please continue.
So the methods we'll be using...
What's "environmental conservation through genetic research"
Species found to be indigenous to Harigaura will be protected.
So if they exist elsewhere, life in Harigaura can die out?
Hear, hear!
Is it really possible to study all the organisms in this area?
Quiet please.
We'll use every means to do our best...
"Do your best"? How irresponsible.
That's won't do.
Such comments won't do.
Not even experts know everything about deep-sea life.
Say it's not possible if it's not.
He's right!
Mining underground resources will harm organisms.
Humans have repeated such acts to advance civilization.
But you have also received its benefits.
The rest...
is a matter of choice.
Hi. - Oh, hi.
"Rokuganso Inn"
I'm home.
Prepare the vegetables, will you? - I have a meeting...
Thank you for waiting.
Here you go.
Welcome.
You're in the Rainbow Room upstairs.
I'll take your bag. - Thank you.
This way, please.
Narumi.
Kyohei!
You're so big now!
That's enough.
How long will you be here?
A week. Until our new salon opens.
I see. Then you have plenty of time to play in the ocean.
Oh, welcome...
I'm Yukawa. I have a reservation.
Did you have enough?
Yes, the food was excellent.
Thank you for finishing everything so neatly.
Did you make all these?
I used to work at a Han cuisine restaurant in Tokyo.
I see.
It was a good meal. Thank you.
You're welcome.
Please excuse me.
Good night.
I'll bring you some rice.
No, thank you.
It wasn't to your taste?
Oh, no, I enjoyed it. Thank you.
Then...
Excuse me.
Where should I go to try some local sake?
OK, I'll take you later.
Thank you.
I'll pour you some tea.
That was your daughter.
Earlier at the lobby.
I heard you were at the meeting.
Involved in environmental matters?
Mrs. Kawahata.
I used to be a police detective until last year.
I was the one who arrested Semba.
You know Hidetoshi Semba, don't you?
No, I've no idea who that is.
I'm not here to delve into your past. I just...
This is a misunderstanding. Excuse me.
Wait, please!
Could you just hear me out?
What's wrong?
Nothing.
Professor.
Narumi said you're a university professor. Right?
So that's why you knew about the foil.
What am I doing now?
Reading the paper.
Don't interrupt me.
You're Narumi's enemy, right?
You're on the side of the bad guys.
I don't take sides with anybody.
I'm on Narumi's side. She's my cousin.
That's so illogical.
Illogi... what?
I'm interested in the pursuit of truth.
Truth is a map that teaches us how the world works -
so humans can choose the right way to proceed.
The role of science is to create that map.
Science? Like in school?
I hate science.
Thank you for waiting. I'll take you now.
I appreciate it.
Kyohei.
Let's play with sparklers.
Sparkiers?
We have leftovers. Skyrockets too.
Yes!
Will you?
See you.
Reaching out online is our best bet.
Yeah. We need support to corner DESMEC.
I'll make a simple website.
I'll help you out, then.
Welcome. Working so late.
Good evening.
Whoa! Amazing!
Then you agree with the mining plan?
No. That's not what I meant.
What will you have?
Any recommendations?
But Harigaura can't beat Hawaii or Okinawa.
Excuse me.
Dr. Yukawa...
I'm from Rokuganso Inn...
The opposition representative. You spoke up a lot.
Mind if I sit here?
What did you mean by, "It's a matter of choice"?
I thought it was a really irresponsible statement.
You're the irresponsible ones.
We are?
You refuse to listen and just keep arguing your position.
But they're doing it, too. You're one of them.
I'm a physicist.
Here as the EM surveying advisor.
Coils are used to measure and analyze seafloor electromagnetic fields.
So mineral resources can be probed without digging.
So it's environmentally friendly?
I'll have another.
It went so high!
Great!
But you said that development always harms the environment.
Japan must face its lack of resources.
And the choice isn't between 0 and 100.
The point of debating is to seek what's best through mutual understanding.
You should choose your way after learning everything.
Here you go. The same one.
Thank you.
All I want is to guard the sea of Harigaura...
To protect the sea as it is.
Get the victim's shoes. The one on top.
Yes, sir.
This is the guestbook.
What time did you stay up last night?
I waited until around 1. a.m.
We were going to wait until morning to call you.
Who's that boy?
That's my nephew.
I'll call you when breakfast is ready so go back to your room.
Is this the man?
That's him.
Was it an accident?
We're not sure yet.
Find anything relevant?
Nothing. - OK.
Take measurements later based on that sign.
Yes, sir.
How high is it?
5.5 meters.
He probably fell from here.
We'll transport him after measuring. Report to the station.
Professor.
A guest at this inn died.
His body was found on the rocks.
The police think he fell off the bank while walking at night.
Don't come here.
It's a major event. A dead body.
But it's impossible.
They found clogs near the dead body.
But nobody could climb that bank wearing clogs.
And it's pitch dark at night. Who would go for a walk?
How insightful.
Aren't I?
Study science if you're so smart.
Don't waste our summer playing detective.
What good is studying science?
Observing water fleas. Testing magnets.
Who cares about those?
That's inexcusable.
Never mind.
Kids should just be studying, right?
To your right.
What?
"Rainbow Room"
Take a look at what he had in his bag.
This.
He's a former cop?
It's unthinkable.
Mr. Tsukahara falling drunk off a bank'?
He'd never do something so dumb.
Mr. Tatara.
Assume nothing during the initial investigation.
Come back later.
I'd take murder into consideration.
Murder?
Go to Harigaura, will you?
Why me?
You really should watch your mouth.
Why do I have to go there?
Here, use this room.
Where's Harigaura? I've got...
Only you can do this unofficial assignment.
What?
Here's the copy of the guestbook.
Look who was also a guest with Mr. Tsukahara.
Playing detective again? The body was here?
The body was over that way.
The bank is too steep for clogs.
What?
You know how Harigaura got its name?
What does "hari" mean?
"Harigaura"
Because this area is volcanic, right?
It's the amorphous material in volcanic rocks.
Wrong!
"Hari" means crystal.
Crystal?
When the sun is high in summertime it shines into the sea -
and the view is like crystals glittering on the seabed.
So it's called Harigaura, the "crystal cove."
The sea is that clear, then.
I wish I could see for myself.
Go dive underwater.
It's 200 meters offshore.
I can't swim that far.
Take a boat, then.
I get seasick.
That's why the map is important.
If you can't find the way to the truth, you can only give up.
That's you right now.
Hey.
Why did Mr. Tsukahara stay at our inn?
I mean, there are other places.
Who knows?
I've no idea.
What happened to your hand? Are you OK?
This? I just scraped it a bit.
Welcome back.
Where are taxis when you need them?
What are these?
Materials for an experiment.
An experiment?
Do you have any PET bottles? Round ones.
Five or six 1.5 liter ones would be great.
Sure, but what are you using them for?
To look inside the sea.
Inside the sea?
Welcome.
Is Dr. Yukawa...
There he is.
Dr. Yukawa.
Ms. Kishitani.
Hello.
Please come in.
Thank you. Excuse me.
Why are you here?
To investigate. You know, that case.
But your jurisdiction is Tokyo.
I need to talk to you.
Are you making something?
A device to help a boy -
understand what science is about.
A boy? But you dislike kids.
Dislike them? I hate them.
You get hives around kids.
He doesn't make me break out.
Why? Is he-logical? A super precocious kid?
What do you want? Get to the point.
Dr. Yukawa, this is a very mysterious case.
Realistically, it's impossible.
A guest at this inn died. Masatsugu Tsukahara.
He actually used to be a detective in Tokyo.
Don't be surprised just yet.
I'm not surprised.
Mr. Tsukahara supposedly fell and died from a brain contusion.
But the autopsy showed that it wasn't the cause of death.
He died from carbon monoxide poisoning.
But that means...
He fell after he died, -
He might have been murdered.
But you can't kill someone outside with carbon monoxide.
Why not? Bum charcoal in a car and poison him.
In which case he'd have to be asleep, but -
urine tests showed hypnotics.
I'm impressed! I don't have to say anything.
Go home.
Why did he...
Why did Mr. Tsukahara come here to begin with?
Ms. Kishitani.
Next, another person comes into the picture.
Hidetoshi Semba, a man found guilty of a murder.
15 years ago, on February 15,1998
a woman was found dead on an overpass in Ogikubo, Tokyo.
This was around 10p.m.
She was identified as 40 year old Nobuko Miyake.
The night before, she'd been with Semba at familiar bar, -
but apparently they'd been arguing.
When investigators came by his apartment, he escaped.
A bloody knife was found in his bag.
Mr. Tsukahara was the one who arrested Semba.
The motive was money problems.
After a full term in prison, he was released in 2006.
After that, -
his whereabouts are unknown.
How is that relevant to Mr. Tsukahara coming here?
Good question.
Semba was originally from Harigaura.
On the day he died, Mr. Tsukahara -
was seen on a street in Higashihari.
The address was a vacant house owned by Hidetoshi Semba.
Semba?
Semba is that...
Yeah, I remember.
"Semba"
Nobody lives there now, -
but Mr. Tsukahara had visited Semba's house.
He hadn't come to Harigaura just to attend that meeting.
Excuse me.
I'll leave your tea over here.
Yes.
What were they saying? - What?
Why is an investigator from Tokyo...
So you're saying Semba might have killed Mr. Tsukahara?
Because he held a grudge against him?
It's possible.
Everything you just said is speculation.
It could all be irrelevant.
That's, why we need your help.
We need you to figure out how Mr. Tsukahara was killed.
I'm busy.
Oh, I forgot something important.
Mr. Tsukahara was senior to our boss, Chief Inspector Tatara.
Mr. Tatara ordered Mr. Kusanagi to solve...
Not interested.
I've got an experiment.
Have a heart. We go back a long way.
Not really, no.
It's working fine. The boiler's OK, too.
They're checking the boiler.
Something about "incomplete combustion."
Dad, this is called an unnatural death, right?
A parked car with someone sitting inside...
I'm fine. I'm not scared.
I'll do my homework. Don't worry. See you.
Your reasoning was correct. It wasn't an accident.
See?
But whatever. We're going to the sea tomorrow -
Don't forget your cell phone.
Everything was normal.
Forgive me at such a time.
I've heard of Hidetoshi Semba.
Really?
Yes.
On the day my husband retired, we toasted with beer.
And I asked him then.
"Which case was the most memorable?"
And he said it was the Semba case.
That he had regrets.
Had regrets?
What did he mean?
He didn't tell me anything more.
Excuse me.
Shall we display his personal effects?
They're in his study so please do so.
Very well.
Professor, where are we going?
You can't swim.
You can't take a boat.
You have to walk, then.
Hello.
Hi. You handle this.
Yes, sir.
This was in Mr. Tsukahara's study.
Some pages are dog-eared.
Cheap lodging houses?
And "manga cafes."
Manga cafes and flophouses...
Mr. Tsukahara was trying to find Semba?
I'll find out.
Amazing!
This is awesome! Wow!
What are we doing?
It's the best way to see the seabed 200 meters offshore.
Shouldn't you be working?
Meaningless debates are a waste of time.
Our economy needs a stable supply...
He said the economy!
Is that so important? Saving the sea...
It sure is important!
Tell us more about the economic effect!
"Dr. Manabu Yukawa"
Let's do it.
Testing.
Wow!
The distance?
What?
The distance. Read the meter.
One, three, five.
135 meters.
Recovery then.
Recovery?
Let's add a bit more pressure.
He's never been here. Too bad.
I see. Then...
Hey girl, looking for someone? I'll help.
Shut up.
Testing.
154 meters.
Recovery.
The sea itself is Harigaura's resource!
Having a pretty sea isn't enough to live on!
Please calm down! DESMEC is trying to explain!
Professor.
How will this show us the seabed?
Think for yourself.
I can't figure it out.
Even so, think for yourself.
There's greater joy in finding the answer.
Testing.
Recovery.
Yes.
The angle's a bit narrow.
Please take your seats!
We'll explain everything!
That guy in the picture...
You know him? Hey!
188 meters!
Let's try adding-more water.
Recovery.
You're doing it again?
Space and bottle rockets are the same.
The more tests, the better.
Not him, but I met the guy looking for him.
When was that...?
Was he... this man?
Yeah, that's him. He was really intense.
He insisted on seeing all our security video data -
What a pain that was.
Mind if I see it all, too?
Hey, you're taking the weight off?
That was for testing.
A cell phone?
Seriously?
Don't answer yet.
This is it.
Let's do it.
Liftoff.
The distance?
203 meters.
203 meters!
Answer it.
Answer the phone.
Oh, it's a video call.
Amazing!
So beautiful!
The experiment was a success.
So fast!
Let me see it, too.
Incredible!
Where do you get the ideas?
Is that what physicists do every day?
Of course not.
Han 113. Find anything up there?
No trace of it being clogged at all.
OK. Get smoke and bring in a gas specialist.
Hari 113, roger.
Hari 112, roger.
What are they checking?
What's up there?
A chimney.
Professor.
Professor!
Want to launch this?
I'm home!
Kyohei!
What's this?
I saw inside the sea with it!
Inside the sea?
Yeah, the professor's cell phone went in here and it went whoosh!
So he was making this!
Hey, give it back!
Wow, this is great.
It was so beautiful.
I was so moved.
Well, he sure is a physics professor, then.
Right?
Kyohei. Did Dr. Yukawa say anything to you?
Like being repulsed by that death?
No, nothing.
Really?
May I eat dinner with the professor?
I don't think he'd enjoy that.
Aw, please? Pretty please?
"Off Limits"
Brought them, Professor!
My uncle will finish bathing in 20 minutes.
I have to return them by then.
The structure of this building is very interesting.
Let's go.
Professor! Not the Rainbow Room?
That's where he was staying.
Wait.
Don't touch anything inside.
Don't touch!
How do you read that?
It's the "Ocean Room."
It's hot in here.
What are you checking out?
Why this a secret?
This room is well kept and clean.
Was that window shut when you did fireworks?
Fireworks?
With your uncle.
It was closed.
Why are you so sure?
We checked before starting.
To keep skyrockets from entering the building.
Your uncle said that?
Yeah, to close all the openings just in case.
Whoa!
Great!
There it goes!
Great!
Why do you ask?
This inn belonged to your aunt's parents?
Yeah, but when my grandfather died, -
my uncle quit his job in Tokyo to take over.
How many years ago?
What?
They moved here from Tokyo, right?
I think they said Narumi was still in junior high.
How old is she now?
She's around thirty.
My uncle said no one wanted to marry her.
Then it was about 15 years ago.
Hey, are you single?
Are you, Professor?
What did your uncle used to do?
He developed car engines.
Engine development.
What are you doing?
What's in there?
What's the matter?
Go return these.
Mr. Tsukahara had been looking for Semba.
Semba became homeless after his release, -
and witnesses say he appeared to be gaunt from some kind of illness.
An illness.
Why are you suddenly interested in the case.
Go on.
But nobody has seen either of them since around May.
Our guess is that Mr. Tsukahara had located Semba.
Mr. Kusanagi says Mr. Tsukahara would have -
hospitalized Semba if he were in such a state.
So Mr. Tsukahara had reason enough to do so.
We're checking the hospitals in Tokyo.
Have you checked up on this family?
What family?
The Kawahatas who run Rokuganso Inn.
The proprietress is from Harigaura and used to work in Tokyo.
Hold on a second.
And they moved here from Tokyo about 15 years ago.
That's around when Semba was arrested for murder.
Do you want a beer?
I'll get it. Want some too, Mom?
"Import Complete"
The Kawahatas' address when in Tokyo -
was Ojihoncho, Kita Ward.
It's Shigeharu's car company housing. On record, that is.
On record?
When the murder happened, -
Shigeharu worked a way from home in Nagoya.
Because Narumi had entered a private junior high, -
Setsuko stayed with her in Tokyo.
While Shigeharu was posted in Nagoya, Setsuko and Narumi -
moved somewhere closer to Narumi's school.
But you don't know where that is.
Right. The company had no record of it.
Find out where they lived.
That information should help prove my hypothesis.
Hypothesis?
Around 15 ears ago, -
where did Semba live?
Funabori, Edogawa Ward.
And the victim, Nobuko Miyake?
Kiba, Koto Ward.
But the murder was in Ogikubo, Suginami Ward. That's pretty far.
Semba confessed at the time that -
he and Miyake quarreled over an unpaid debt.
Why would they argue there? It's unnatural.
The reason that connects those four places -
links Semba and the Kawahatas.
Mr. Tsukahara realized that. So he came to Harigaura.
Yukawa. You knew who killed Mr. Tsukahara, don't you?
Who did it?
Shigeharu Kawahata.
But a hypothesis becomes the truth only when proven.
So don't inform the local police just yet.
This is a very delicate case.
Handle the investigation with care -
or one person's life might go terribly awry.
Awry?
Dr. Yukawa, do you mind?
Thank you.
Hello.
Could you comment on the EM survey?
Everything is in the documents.
No, for the local paper. About the difficulties you face.
Difficulties?
I don't face any difficulties.
Why not interview your own people for that?
Let me ask you something!
There will be a Q&A session later.
So the drilling's starting, ignoring local residents' voices.
This is a research vessel, not a drillship.
The effect on the marine environment is the same.
This is an AUV. Autonomous underwater vehicle.
It inputs the underwater topography -
and maintains a fixed distance from the seafloor.
So this research vessel doesn't damage the environment.
Weren't you listening?
You think we haven't studied enough.
Development or environmental conservation. It's a major issue.
Choose your way...
"After learning everything," right?
You must study harder.
Talking with you is exhausting.
Likewise.
Kyohei said you helped him I see underwater. He was thrilled.
I wanted him to learn something.
Didn't you feel anything when you saw Harigaura's sea?
It was spectacular.
Wasn't it?
"Welcome to the crystal sea."
I saw your blog. When did you start it?
About 10 years ago.
"The sea is Harigaura's treasure."
"I am its guardian."
Why are you so attached when you're not even from here?
Because I love the sea. Is that so strange?
It's as if you're waiting for someone.
I get the impression that you're trying -
to guard this sea until that person comes back.
You sure are a physicist. You think too much.
What are you doing?
My apologies. It was such a great angle.
See? Beautiful.
Excuse me.
Narumi Kawahata's address was in Ojihoncho, Kita Ward.
That's her father's company housing.
She actually lived somewhere easier to commute.
Are you investigating a case?
I can't tell you much else.
She was only here a year.
I see.
Was she involved in club activities?
That's nice, Kyohei. Dinner with Professor.
Here, this is homemade.
Thank you.
Are you doing your summer homework, Kyohei?
I'm doing it, but...
I'm not sure what to do for my research project.
You saw inside the sea.
We calculated and tested many times until success.
Yeah.
It's an ideal summer project.
You're right.
Curiosity is the best fuel for people's growth.
Curiosity?
For example...
What's this made of?
Paper?
Yes, paper.
It's paper, so why doesn't the bottom part burn?
Isn't it mysterious?
It is. Why doesn't it bum?
What's inside this pan?
Clam and shrimp.
And?
Vegetables.
And?
Soup.
Right, soup. Water, that is.
The boiling point of water?
100 Celsius. We did it in school.
Water evaporates at 100 degree Celsius.
Conversely, water in liquid state won't become hotter.
So as long as there is soup ii this paper pan, -
it won't burn even when heated.
You've learned something.
Will this burn, then?
What if I put this on here?
The water will evaporate from the heat. It'll burn, right?
I wonder.
Let me try.
What's wrong?
Eat the dried shrimp while it's hot.
I'll get in touch with you if I'm ever in Tokyo again -
See you. Bye.
Narumi?
What's wrong?
She asked...
"Where did you used to live?"
Who asked?
She said the police came.
Who said? Who asked you?
Yukari from the junior high tennis club!
Narumi! Calm down...
Mom... it's...
Narumi, listen. It's a secret, right?
It's our secret forever, remember?
It's over now!
Stop it!
It can't be kept a secret!
Don't touch me!
Calm down! Listen to me!
Stop it!
What's going on here?
Setsuko.
Dr. Yukawa knows.
It's over now.
We got the address.
When the murder happened Setsuko and Narumi lived in Ogikuho.
Close to where Nobuko Miyake was killed.
The Kawahatas...
The Kawahatas moved to Harigaura two weeks after it happened.
So Semba and the Kawahatasi are linked now.
Has he been found?
We're working on it, but no luck.
But once we find him, we can prove Shigeharu killed Mr. Tsukahara.
The circumstances have changed.
What?
I've been asked to leave tomorrow.
Shigeharu Kawahata is turning himself in.
He's what?
Professor!
You're at the same hotel, right?
My dad's coming tomorrow.
You probably shouldn't be here.
Let's go.
I was playing with fireworks with my nephew that night.
Mr. Tsukahara had come to the kitchen a little earlier -
and asked for a strong drink.
A drink?
Said he couldn't sleep well while traveling.
So I gave him some sleeping pills.
You had some in your possession?
I used to suffer from insomnia.
"Sleeping pills"
I had them prescribed at Naito Clinic.
I'll go confirm.
And then?
So high!
Great!
After doing the fireworks..
I called the Rainbow Room.
To confirm the time for his breakfast.
But he didn't answer the call.
So I went to his room to take a look.
I saw that the light of the Ocean Room was on...
And Mr. Tsukahara was lying unconscious.
Something smelted sooty, -
and I knew what happened.
Carbon monoxide poisoning?
Yes. So I rushed downstairs to the boiler room -
and sure enough, the boiler had stopped working.
Adding smoke from the boiler room.
Hari 112, copy.
Go ahead.
The pipes connecting the boiler room -
and the chimney on the roof -
run through the walls in our building.
It's not clogged.
But the building is old now.
There are cracks all over the walls of the rooms -
and it seems the pipes inside were damaged as well.
In particular, -
the Ocean Room had smelt sooty before from time to time.
So we hadn't been using that room.
After that, -
my wife came back after driving another guest to the bar.
Mr. Tsukahara is dead.
He's lying dead in the Ocean Room.
I don't get it.
Why was he in the Ocean Room when he was staying in Rainbow?
Maybe he wanted to see our fireworks.
Fireworks?
The Ocean Room faces the yard.
How did he enter the room?
Was it locked?
No, we had it kept unlocked.
It was a hassle when cleaning.
So he moved over to the Ocean Room to see fireworks -
and soon the sleeping pills kicked in and he fell asleep?
I think so.
Why didn't you call the police then?
My wife said we should.
Let's call the police!
No! We can't!
Let's get rid of him.
If word gets out that he died here, -
this place will go under!
How did you do it with your husbands bad leg?
At the time...
We were desperate...
What are you doing? Hurry!
We managed to put him in the van...
His glasses!
Don't touch with your bare hands!
There's no excuse for -
what we did to Mr. Tsukahara.
I'm very sorry.
I am truly sorry.
They confessed. Involuntary manslaughter and abandonment of a corpse.
Lying?
Shigeharu's confession's detailed.
He couldn't possibly tell the truth.
Then Setsuko -
is an accomplice?
Shigeharu probably killed Mr. Tsukahara alone.
Killed him?
How did he do that?
They confessed.
Why would they lie?
They have secrets to guard.
Secrets?
Everyone in that family has a secret.
Setsuko and Narumi have a secret they share, -
but Shigeharu is also deceiving them.
Mr. Tsukahara stepped into -
the web of secrets and was killed.
And now...
...one person's life is about to go awry.
Oh, so beautiful.
That was 30 years ago now.
I look younger too, don't I?
They met here, didn't they?
Setsuko worked hard and was sensible.
He carried our idol away.
"Hari Cuisine - Haruhi"
Setsuko is so beautiful -
Excuse me.
Is this Mr. Hidetoshi Semba?
Yes. Mr. Semba was from Hari, too.
He was doing well around that time. See?
So you're investigating that case after all.
Were Mr. Kawahata and Mr. Semba friends?
I'm not sure.
Probably just acquaintances.
All the guys who came had their eyes on Setsuko -
And Mr. Kawahata won her heart.
He was a nice man.
Hey, this photo...
"Setsuko and Narumi, 2 months old." Where...
It was gone before I knew it.
One of Setsuko's fans must have taken it.
But just between you and me, -
Setsuko was really in love with Mr.Semba.
Um... Do you know if the two were intimate?
Who knows?
Mr. Semba was married.
Oh, is this his wife sitting next to him?
That's Nobuko.
Nobuko...
Oh, Nobuko Miyake?
It was a pity how she died, -
but frankly, I didn't like her very much.
She was sloppy with money.
29 years ago, Setsuko chose Shigeharu Kawahata over Semba.
13 years later, Semba killed Nobuko Miyake.
What circumstances would lead to that?
Mr. Tsukahara, who had arrested Semba, -
said that he had regrets, right?
What does that mean?
You already have an idea, don't you?
The Nobuko Miyake murder case -
was a wrongful conviction.
Semba didn't do it.
Watch what you say.
He didn't deny the charges during interrogations -
or the trials.
Why?
Semba did time to cover for someone.
But the only person who realized that -
was ironically the man who had arrested him.
That's why Mr. Tsukahara went looking for Semba -
to hear the truth from him.
So the one who killed Nobuko Miyake -
was Setsuko Kawahata?
That's what I thought at first.
That Semba sacrificed himself for Setsuko.
But when the murder happened, -
they'd been apart for over a decade.
Would you be willing to bear the blame for murder, -
giving up everything for someone you loved 10 years ago?
Probably not.
I couldn't, either.
This realization helped me think from a different angle.
Semba tried to protect -
someone much closer than a former love.
Who could that be?
Not Setsuko, -
but her daughter.
Daughter? Narumi Kawahata?
She's not Shigeharu's daughter.
She's Semba's daughter.
And to seal that secret, -
she herself murdered Nobuko Miyake.
Hi there. Is your mom home?
No, she's out right now.
Is your dad out, too?
Yes.
I see.
You're her daughter, right?
Yes.
I knew it.
It's cold so let me wait inside.
No, wait, you can't come in.
I'll leave as soon as Setsuko returns.
Who are you?
I'm an old friend of your mom's.
You guys seem pretty well off.
"Narumi, I'll be at our place in Ojihoncho."
Are you ever told you resemble your dad?
Guess what?
I know the truth.
Your lips look exactly like his, you know.
"She doesn't look like you."
What?
I was told she doesn't look like me.
Let me take this. I'll be back.
Give it back!
Stop glaring at me.
Who do you think you are?
Tell Setsuko to wait for me with her passbook ready.
Give the picture back!
I'm so sorry, Nammi!
It's all my fault.
"Hidetoshi Semba Arrested"
"St. Joseph's Hospice"
This isn't what I expected.
I thought hospices were more austere.
All the patients here don't have much time left.
Dr. Yukawa.
This is Mr. Hidetoshi Semba.
Mr. Semba, are you all right?
Call us if you need anything.
Please take your time.
I'm Misa Kishitani, Tokyo Metropolitan Police.
This is Dr. Manabu Yukawa. He's a physicist.
Nice to meet you. I'm Yukawa.
Thank you for your time.
I was in Harigaura until this morning.
To research seafloor resources.
The sea of Harigaura is truly beautiful.
It's probably no different from how you remember it.
We scientists don't want to destroy such beauty, either.
There's something I'd like you to see today.
It's a certain person's blog.
"Welcome to the crystal sea. I The sea is Harigaura's treasure."
"I've taken it upon myself to become its guardian."
"Please come see its color for yourself."
"I'll be here"
"waiting for you always."
This blog belongs to...
this woman.
She guarding that sea.
She believes that it's her mission, -
that she's returning a favor by doing so.
That was my impression.
To see this woman, -
Mr. Masatsugu Tsukahara -
went to Harigaura.
It was for your sake.
You do understand why, -
don't you?
No, I don't.
I...
I don't know anything.
I see.
Thank you very much.
Thank you.
Tell her, "Thank you."
"Thank you"
"for guarding"
"the sea of Harigaura."
Please tell her.
I will.
Is that all you're doing?
I have change.
I never knew you had a kid.
Hey!
No, wait. Just a sec.
Give it back!
Isn't this Setsuko?
Hey!
No problem.
Why do you have such a photo?
No reason.
Tell me why.
Why?
There's no reason.
A 40-year-old woman was found dead -
on an overpass in Ogikubo last night.
Hello, Kawahata residence.
Setsuko, it's me.
It's me, Semba.
Mr. Semba?
Did Nobuko show up last night?
Nobuko Miyake! To extort money from you!
I don't understand.
Turn on the TV! Hurry!
Hang on...
The woman has been identified as Nobuko Miyake of Kiba...
Nobuko...
Around 10 p.m. yesterday a passerby called police -
after finding a woman bleeding on an overpass in Ogikubo...
Setsuko!
Narumi!
Hello?
Narumi! Wake up!
What happened?
Narumi! Narumi!
Narumi! Calm down!
Narumi.
Setsuko. - Mr. Semba.
Is that it?
No, wait.
No need to worry.
But...
My company went under and my wife is dead. I'm alone.
Wait!
Over there, in that coffee shop...
In the brown coat.
She's all grown up.
Thank you, Setsuko.
Mr. Semba...
Semba took the blame and served out his sentence.
He's now dying from a brain tumor, -
about to live out his life protecting a loved one to the end.
But what about Mr. Tsukahara's death?
If the Miyake case isn't proven, Shigeharu's crime...
Can't be substantiated.
The Miyake murder case is closed.
That is, there's no reason to kill Mr. Tsukahara.
We've lost.
Are you happy with the way this ended?
You said someone's life was about to go awry.
Not happy at all. So we're returning to Harigaura.
I don't know where we can leave My sister is involved.
I'll probably be questioned, too.
Kyohei? Yeah, he seems to be all right.
He's eating.
We can't postpone the grand opening.
So high!
Great!
Welcome.
We have no time until the next survey.
Tomorrow I'll ask Dr. Yukawa to explain -
the benefits of EM surveying methods.
Let's eat and get some rest.
It's paper, -
so why doesn't the bottom part burn?
Isn't it mysterious?
What's wrong? Are you OK?
Oh, I'm sorry.
"Dr. Manabu Yukawa"
Shigeharu Kawahata, you've got a visitor.
Dr. Yukawa.
Go in.
Your cane.
You've got 20 minutes.
Yes.
Please sit down.
The police are stumped.
Their simulation experiments for carbon monoxide poisoning -
haven't succeeded.
The concentration isn't lethal.
But I can simulate what occurred that night.
That wasn't an accident.
It was murder.
Mr. Tsukahara was killed.
I didn't...
No, you didn't do anything.
The person who did it -
was Kyohei.
I don't get...
The police had come to Rokuganso inn.
As the investigators came down from the roof he said...
What's up there?
A chimney.
I was surprised.
There was no way of knowing that from down below.
But he knew.
So he'd been up there before.
And...
He climbed the ladder up the chimney because you couldn't do it.
Dr. Yukawa...
Kyohei told me.
To keep skyrockets from entering the building.
To close all the openings just in case.
He put a lid on the chimney.
You instructed him to.
Did he use a cardboard box?
Wetting it down and covering the vent is enough.
Of course, before all that, -
you had to give Mr. Tsukahara an excuse -
to move him to the Ocean Room.
I'll take that.
No, no. Oh, thank you.
This is the Ocean Room. Please.
And had to put him to sleep there, -
How to give him sleeping pills?
This is on the house.
Yes, put some in the sake.
My wife will come by later to lay down your futon.
Yes.
Excuse me.
Your plan begins to materialize then.
With the vent covered...
the flue gas flows backward.
Eventually incomplete combustion in the boiler -
generates carbon monoxide.
Which then flows into the Ocean Room -
from the cracks in the wall.
You used to develop car engines so you must have foreseen it.
That the CO would become lethal in less than 10 minutes.
Whoa! Amazing!
I'll do it next.
Are you sure? Be careful.
Two in a row next!
Afterwards, you made Kyohei bring back the lid over the chimney -
and confirmed Mr. Tsukahara's death.
Everything went according to your plan.
Now then, -
why did you have to kill Mr. Tsukahara?
My friend in the Tokyo Metropolitan Police checked up on Hidetoshi Semba.
Semba had -
supposedly killed a woman named Nobuko Miyake before.
Please stop.
But the killer wasn't him.
Shut up!
It was Narumi.
It happened -
while you were working in Nagoya.
But you guessed what had actually gone down.
"Acquaintance arrested for murder."
Because you knew -
that Narumi was Hidetoshi Semba's child.
But you'd kept it hidden.
For 13 years until the incident and 29 years total, -
you'd accepted Narumi as your own daughter.
I was told she doesn't look like me.
They're right, though.
Of course you don't.
I can't imagine how hard and painful -
that must have been.
But there's only one reason you could have endured it.
It's because -
you love Narumi with all your heart.
You raised her -
as if she were your real daughter.
You must have known that the reason why she tried so hard to protect -
the sea of Harigaura was her longing for her real father who had -
sacrificed himself for her.
Narumi!
But even so, -
you watched over her in silence.
Each member -
of your family had a secret.
But those secrets -
were kept from each other -
because you all loved one another.
However, -
Mr. Tsukahara came into the picture.
This is a misunderstanding. Excuse me.
Wait, please! Could you just hear me out?
What's wrong?
Nothing.
He must have filled you with trepidation.
A sinister messenger about to open the door to a past you wanted to bury.
Your family would be ruined if he were kept alive, -
"Boiler Room"
Of course, you probably expected it from the start.
The police would discover that the cause of death was CO poisoning.
That he had actually died in Rokuganso Inn.
The charges would be involuntary manslaughter & abandonment of a corpse.
The truth wouldn't be exposed.
Your secret would be safe.
Narumi would be safe.
You certainly are a scientist.
I'm very impressed.
But what you just went on about -
was completely off the mark.
That was one heck of a story.
I...
I have no secrets -
from my wife or Narumi.
There's never been -
anything hard -
or painful about my life.
She is still, but...
You know, Dr. Yukawa, -
Setsuko was stunning when she was younger, -
and so sweet to boot.
All the guys around her would fall in love with her.
She was out of my league, -
and yet she married me.
The happiness I felt then -
hasn't changed even now.
Of course I love the beautiful daughter Setsuko gave me.
She's mine. Narumi is my daughter.
So my hypothesis is incorrect?
Yes.
I see.
I hope you'll forgive me -
for wasting your time.
Please take care.
Just one last thing.
Anything you'd like to say to Kyohei?
That I'm sorry...
It was such a good summer vacation before all this, -
and I'm sorry.
Very well.
Narumi.
Dad.
I'm sorry.
About Dad...
He knew everything.
I see.
If word gets out that he died here, -
this place will go under!
Was this really -
an accident?
Of course it was.
Help me!
Hurry up!
Are you OK?
You're drunk. Enjoy the reunion?
"She doesn't look like you."
What?
I was told she doesn't look like me.
Mom, listen...
I've decided to...
Narumi.
Make sure -
you eat well, OK?
Thanks for coming along.
It was unforgettable.
Thank you, too.
You gave me a chance to say goodbye.
Dr. Yukawa.
I'm ready to be punished.
"Thank you for guarding the sea of Harigaura."
Mr. Semba asked me to tell you.
You're loved and protected by everyone.
I really don't deserve to be.
But you have a mission.
A mission?
To protect Kyohei.
Luckily we can go so soon.
I thought they'd detain us for days.
Dad?
What happens if someone had really done that on purpose?
Done what?
About that man dying at Rokuganso Inn.
If it were on purpose, it'd be murder. Don't be silly.
Good morning.
Check-out, please.
Yes, sir.
Will this bum, then?
Like this?
Will you go put that over the chimney?
The chimney?
What's wrong?
Shall I check? - Please.
Kyohei will realize someday.
Realize what he had done.
From that moment on, he'll blame himself -
and be burdened with a secret.
But at the same time, he'll want to know.
He'll want to know why his uncle made him do such a thing.
And when he comes to you for answers, -
I want you tell him the plain truth without holding anything back.
The plain truth... without holding anything back.
So he can choose his way -
after learning everything.
Two in a row next!
Thank you. - Thanks.
We've got time so I'll get some juice.
Professor!
I heard you were leaving today.
The data from our rocket experiment.
You can't do your homework without it.
Professor...
I shouldn't have done those fireworks.
We had fun.
This summer, -
you learned a lot.
Every problem has an answer.
But that doesn't mean the answer is easily derived.
From now on, -
you'll experience many such instances.
So will I.
But no need to fret.
If we continue to grow, -
we should be able to reach the answer.
Until you find your answer, -
I'll think with you.
I'll struggle to find it with you.
Don't forget.
You're not alone.
Yes.
Yeah, we're about to get on the train.
Are you satisfied?
Yes.
Summer's almost over.
Changes in flying distance?
L equals v naught squared sine 2 theta over g...
Gibberish.
The distance?
Recovery.
Liftoff.
Whoosh.
