Original subtitles

We, the Japan Coast Guard and Tohto Heavy Industries

have been in collaborative work.

Information on the ship's automated navigation system has been leaked to the outside.

It was leaked by Dr. Seno of the THI's Marine Research Institute.

That's not all.

There's a traitor in the Coast Guard who is in touch with the Doctor.

Japan Coast Guard Guard and Rescue Department of 3rd Regional Coast Guard Headquarters NARIAI ATSUSHI

Immediately, take him into custody!

NO!!!

Papa?

Nariai!

Nariai!

Nariai!

Are you all right?

Listen. I'll be right back, okay?

Nariai.

Is this what you're looking for?

Why do you...

I get it now.

You're the spy.

"JAPAN COST GUARD" "Yokohama Maritime Disaster Prevention Base"

Japan Coast Guard Deep Crime Unit (DCU) Captain NIINA MASAYOSHI

I am Seno Haruki, newly assigned to DCU.

Japan Coast Guard Deep Crime Unit (DCU) Member SENO HARUKI

I'll work hard from today!

You're finally here, Seno!

I haven't seen you since the training in New York.

Long time no see, Nishino-san.

I mean, Vice Captain Nishino.

Japan Coast Guard Deep Crime Unit (DCU) Vice Captain NISHINO TOMA

Morita-san.

Japan Coast Guard Deep Crime Unit (DCU) Member MORITA NANAO

Otomo-san, too.

Japan Coast Guard Deep Crime Unit (DCU) Member OTOMO YUYA

Here you go.

We'll leave the gear here.

Thank you.

Is that rebreather?

Yeah.

Hefty!

Hey, you.

Yes?

Are you gonna let your seniors carry the heavy gears?

Oh...

Morita-san.

- I'll carry it. - Thanks.

She is Kanda Ruri-san of the Cyber Squad.

Japan Coast Guard Deep Crime Unit (DCU) Cyber Squad KANDA RURI

Huh?

Looking for Captain?

Yes.

Captain!

How was your training for Counterterrorism in NYPD?

I honestly was daunted.

It was more than I could have imagined.

I was the only Japanese there.

Japan will soon be no stranger to this.

- Huh? - That's what the DCU is for.

Certainly!

I am sure my brother will be happy

Japan Coast Guard Deep Crime Unit (DCU) Member NARIAI TAKAKO

to see me working with you here.

I'm sure he will.

New Investigative Unit of the Japan Coast Guard,

Deep Crime Unit.

Abbreviated DCU.

DCU is not limited to the area where judicial police rights are exercised.

It is Japan's first ever special judicial police official

which authority isn't limited to the ocean but also over all of Japan.

It investigates crimes and accidents related to rivers, lakes,

Japan Coast Guard Head of Guard and Rescue Department SAKUMA YUJI

and other bodies of water.

There are also a newly established cyber squad and forensics lab

that deal with counterterrorism and violent crime, among other things.

The six members of Task Force One

have endured two years of intensive training

with the U.S. Navy SEALs.

They are the elites.

The squad will be led

by Captain Niina Masayoshi.

Captain Niina will now explain from here.

I am Niina, the captain of DCU of the Japan Coast Guard.

The Japan Coast Guard was established in 1948...

Hey, is the rumor true?

That Director Sakuma pushed for Niina-san to be the captain.

Talk about sensible, the captain would be Nishino-san.

Of course.

Nishino-san was the ace of the Special Rescue Team.

Silent, both of you.

We just follow orders.

We, the DCU, will be investigating and rescuing cases that occur in all water bodies.

Including defense against foreign enemies,

we are equipped for any situations.

We are a group of experts.

The peaceful and affluent ocean that our ancestors have continued to protect.

With the belief that we will pass it on to the next generation,

we will live up to the peace and expectations of the nation.

We got a case.

Understood, we'll be right there.

Morita, Otomo!

We'll be working with you!

Pleasure.

Come on.

I never thought you'd make it this far.

I will do my best, Captain.

- I have high hopes for you. - Yes, sir.

Part of a dead body found at Hashibe Dam in Gunma Prefecture.

One month has passed since the death.

DNA analysis results

showed that it belonged to the former president of Keikoku Corporation, Mouri Hajime.

- Mouri? - You mean, that Mouri Hajime?

That's right.

Five years ago, he embezzled 30 billion of the company's fund.

As soon as the allegations surfaced,

he fled the country in a flash, evading the police and the press.

That Mouri Hajime.

On the piece of flesh attached to bones,

hydrochloric acid was found.

It's a strong poison that could melt the skin if touched.

As you know, there's a typhoon coming.

If we don't hurry, we'll be unable to investigate.

- You hear me? - Yes, sir.

Kanda, is all set?

Already in place.

According to prefectural police,

the typhoon that passed through the area a week ago

caused the water in the dam to move.

The body was moved.

And now, part of it was found on lakeshore.

Therefore, based on the data, the DCU AI calculated the following.

A depth of 50 meters.

The rest of the bone is thought to be sunken in this area.

50? We need rebreather.

Get the drone ready.

We'll decide if it's needed after seeing the site.

I never thought their first mission would be a dam.

I've made prior adjustments with the Gunma Prefectural Police.

To see us, the Coast Guard are investigating on land,

Deputy Director of Japan Coast Guard HAYAKAWA MAMORU

the police don't find it amusing, after all.

I understand.

Can they carry it out?

If anything goes wrong, you take the blame.

Certainly.

Do they know how many meters deep they're diving?

Decompression sickness awaits them if they dive too deep.

Nobody has dived down to the bottom of this dam since it was built.

Until now, dams have not been a domain of the Coast Guard.

But that's where the true value of us DCU comes into play.

Water is water, after all.

Yes, sir!

OK, we'll go with rebreather.

The drone follows.

All right!

The image from the camera attached to the goggles will be reflected on this screen.

Captain, you'll give the orders here.

No, I'll dive.

What?

"If you're a captain, stay up here and give orders."

"You're too old for this, read the air."

Is that what you thought?

Oh please! Nobody here thinks so.

For the record, I can't read the air,

but I can read the water.

Seno and I will go down there.

Takako and Otomo, follow through.

Nishino and Morita stay up here.

I'll command up here then.

No, I'll command underwater.

Wait a minute. Normally...

Guess that "normal" doesn't work here.

This is my team.

You're under my command here.

What are you waiting for? Get ready.

Yes, sir.

Huh? I don't see any breathing bubbles from Captain Niina and the others.

This is rebreather.

It doesn't throw breath away.

It circulates through the system, processing it for rebreathing.

That way, you can dive efficiently and for a long time.

Even in the Coast Guard, only the captain, Nishino-san, and Seno can handle it.

Which means this is a place only the DCU can dive.

Is 50 meters considered safe?

That's like 20 floors of an apartment building.

After 20 meters, the water temperature drops drastically and the movement slows down.

A single error in judgment can be fatal and cost you your life.

Scary!

That's why this qualification can't be merely taken,

because it's next to death.

Hard to believe this is their first time, they're so buddy-like.

Focus on the mission.

Yes, sir.

From there, go 50 meters in a 45-degree direction.

No, we go through the tunnel.

I want to check the hot spring source.

Tunnel?

This is the drone's limit.

The area around the tunnel was cleared before it was dammed

but some of the buildings are still standing.

It is said that this tunnel was built during World War II.

The mine wall is weakening and may collapse.

Please be careful.

Is the platform still sinking?

Arrive at the center and explore the surroundings.

Station signboard?

Agatsumayaki?

Why's it there?

This place used to be a pottery production center before it was dammed.

30 meters in a 60-degree direction ahead

is the target location.

Captain stayed still.

Is everything all right?

- Captain! - Silent.

I'm listening to the water.

subtitles by aoinousagi

Attention!

Bow!

At ease!

I am Niina of DCU of the Coast Guard.

I'd like to start with a report on our investigation.

This investigation will be led by DCU of the Coast Guard.

We, the Gunma Prefectural Police,

have been ordered by the Chief to follow their instructions!

Let's begin.

Kuroe.

We analyzed part of the body that DCU recovered from the dam lake today.

Similar to what has already been found,

it matched on Mouri Hajime's skull part.

Death time is still estimated to be a month ago.

What about security cameras?

We've been checking the security cameras

near the dam for the past two months

and haven't found any suspicious activity.

Was it hydrochloric acid that killed him?

Most likely it.

However, there is too little information to identify.

We need you to find as many bones as possible.

Understood.

What about simulation of the murder circumstance?

I ran a simulation on the DCU AI based on the prefectural police's investigation.

The body is thought to have been murdered in some way

and then dumped in Agatsuma River upstream,

where it flowed to the dam lake.

That's all we have.

Anything from the prefectural police?

Have you interviewed Keikoku Corp.?

What's going on?

I've already made an appointment for that.

We will go tomorrow.

Investigating on land is our job, the police.

No.

If you think DCU only investigates underwater, you're mistaken.

Land is also our area of investigation.

We will go to Keikoku Corp.

We have no choice then.

So what's your plan for the investigation?

I'm thinking we should get the rest of the body first.

Therefore, I'd like the prefectural police to search

the river where the dumping took place.

Search the river? Us?

In the dark of 50 meters depth,

with your fumbling investigation,

do you think you can do it?

Water is different from land.

Fine.

Also, I'd like you to search the area

and identify the source of the hydrochloric acid.

"Investigate a hundred times."

I know using feet is your forte.

Good luck.

Dismissed!

Captain, this is essentially the police territory.

To them, we're just outsiders!

Please read the air...

Why can't we create some air?

If they belittle us, it's over.

You're still as arrogant as ever, I see.

Long time no see, Niina-san.

Or... Captain Niina, I guess?

What is the MPD Public Security doing here?

Mouri Hajime is initially the target we've been after.

And on behalf of the MPD,

I'd like to see how the Umizaru works.

How attentive.

Well...

- At the most... - Whoa! Kamameshi!

It looks good!

It is good!

Seno, get one for everybody.

Get two for me.

- Well, we're taking 7. - Sure thing.

Should we get one?

- Can I have these chopsticks? - Sure.

The dam project is the main business of Keikoku Corp.

They seem to be expanding widely in Japan and overseas.

This is the list of employees who were close to Mouri

before he fled the country five years ago.

This man in particular, Managing Director Osanai Shoichi

was the dam construction's project leader at the time

and is said to have been the person Mouri trusted the most.

He's said to be a very capable man and was able to rebuild the company

within five years after Mouri's escape.

But at the same time, a bad rumor arose.

Bad rumor?

Actually, it's rumored that he helped Mouri embezzle

and got billions of profit discreetly.

Moreover, it is said that he framed Mouri for all the crimes

and forced him to flee the country.

If that's true, he'll be in trouble if Mouri's back.

So he killed Mouri to hush him.

First, we will focus on the dam.

Takako, meet up with the prefectural police.

- Interview the locals. - Yes, sir.

Nishino, Otomo and Morita

delve the dam with rebreather and drone.

Seno and I will go interview at Keikoku Corp.

Yes, sir.

Really?

Sorry, he's back. Call you later.

Okay. Bye.

Welcome home.

Did you bring Kamameshi?

Pretty good.

You can't taste it while you're working.

Who told me to find as many bones as possible?

We need to get results.

Your head's full of DCU.

Was that Takako on the phone?

I heard you did it right away.

Your bossy speech.

What a big mouth.

It's a speech of our proper plan.

You've always been haughty.

Or... is it your intent?

What else did you talk about?

Nothing else.

You haven't told her yet?

I want to tell her face to face.

Isn't it unusual to have leek in kamameshi?

Here, aaa...

Surprisingly good.

The gentlemen from DCU of the Coast Guard are here to see you.

Let them in.

Please come in.

The Hashibe Dam is your work too?

Yes. I was in charge of it.

I heard that the dam project is very difficult due to

opposition from the local community.

I consider that as a part of the dam project.

I see.

Have you heard of the former President Mouri's incident?

The news said it happened a month ago.

I didn't know he was in Japan.

Have a seat.

Any contact with him since he escaped five years ago?

I would've reported it if there was one.

The police were also investigating enough five years ago.

What a groundless accusations.

Still, there's no smoke without fire.

Osanai-san, can you tell us about your activities

a month ago?

- Watch out! - I'm sorry.

This is just to confirm with everyone.

Wakabayashi-kun.

Yes, sir. Excuse me.

What was my schedule a month ago?

Last month, the Managing Director went to San Francisco

to inspect the tunnel construction project.

I see.

Fair enough.

That's it.

They're leaving this place now.

Yes, sir.

I'll send you off.

With such poor visibility, using drone would be impossible.

It's the same when I dive.

I couldn't see anything.

And we still have so many inspection points.

Even so, Nishino-san has already covered so much of it by himself.

Obviously!

He was featured in a TV documentary.

- He's the Coast Guard superstar! - Yeah, yeah, OK.

I think the captain should have been this guy after all.

You didn't find anything in the river?

Did you search properly?

I'm sure you'll find a bone or two.

Agatsuma River is only a meter deep!

Captain!

We're not as good as DCU,

but our divers are veterans who've searched the river many times.

Don't bother then.

Apparently it was too much for the prefectural police?

We, the DCU, will take care of the river.

Just please make use well of your forte, investigating on land.

Nishino-san.

How can he have such attitude as a person?

The prefectural police are backing off?

You pissed off the police, what now?

Anyway, the prefectural police are switching this case over to the MPD Public Security

and won't cooperate with us at all in the future.

Very well, sir.

Niina, are you sure you can handle this?

I will certainly figure something out.

By any means necessary.

Isn't it hard for us if the prefectural police won't cooperate?

What are we gonna do now?

Well, of course you guys are gonna do it.

No way. Are we not gonna sleep?

Enough with your nonsense!

Let me take this occasion to say this.

Your methods are unbecoming of a captain.

- Nishino-san, that's a bit... - Let him, Takako.

Are you trying to tell me that you could have done better?

If it were me, I wouldn't put my team in danger

by giving them even more burden like this.

At least I won't make the mistake of aggravating the police.

Burden, eh? And what will you do?

If you disagree with the way I do things, will you quit DCU?

No. If anyone should quit, it's not me,

but you.

Sounds great. I'll consider it.

However, my investigation is far from over.

I'll do whatever it takes to get what I want.

If you don't want to keep up with me, just don't.

He might be just haughty, but

I think he's really care about the team.

Are you trying to tell me you know everything about that man?

You got into the Coast Guard on his recommendation, right?

The beautiful tale of how he saved a boy from the incident 15 years ago,

nobody knows the truth.

What do you mean?

The only report on record is the one he made

and he can lie about it all he wants.

Maybe...

You've been duped, too.

Hey!!

Okay, enough!

Stop right there!

We'll be busy again tomorrow, so help me clean up.

OK? Come on.

Long time no see, Haruki.

How have you been?

What, you're not swimming?

Because I can't swim.

In that case, I'll teach you.

I'm sure you'll find a whole new world underwater.

You know, it's great underwater.

Maybe... I'll give it a shot.

All right! Let's go!

Take your marks.

Not a bad time. You did great.

Yeah.

You don't look happy, though?

This silver medal is the result of all the hard work you've put in.

I was aiming for the first place.

Okay, so this is the wrong color.

If you want to achieve your goal, do whatever it takes.

Next time, even if a foul play is needed, go get the gold.

Don't take personally what Nishino-san said.

I do, of course.

I was so shocked by the explosion, I can barely remember anything from that time.

Had I remembered, I could've said something back.

You don't have to.

Even if you don't remember,

you've now become a decent rescuer.

That's more than enough.

I'm so pathetic.

Your brother passed away because of me.

But you've always encouraged me, Takako-san.

I'm really sorry.

Don't say that.

You're the one my brother risked his life for.

I'm happy to work with you!

Nishino-san, I'll be leaving now.

OK. See you tomorrow.

Good evening.

Mako-san!

I think Captain... is in the pool.

Yeah, I know.

So... you need me?

He's competing again in the pool today.

With himself?

His opponent is... Nariai-kun.

It seems he's been in losing streak.

He's still the same as he was.

So am I.

I still can't forget

about Nariai-kun.

Just forget him already.

You're getting married, aren't you?

I can tell.

Your phone call the other day felt unusual.

Because you're Nariai-kun's little sister.

I want to tell you properly.

Mako-san.

Get married.

Forget him.

And live happily!

You've my blessing as his sister.

I approve of you.

Mako-san! Hey...

What about the wedding?

He said just registering it is enough.

What?

You have to hold a wedding ceremony!

It's important to draw a clear line.

I'll arrange things up.

What? No, don't.

I'll get mad.

That's better.

Instead of crying.

Mako-san.

Congratulations!

Captain!

What?

Was it the body? Did you find it?

See Nishino-san.

Good morning, sir.

I thought you hated working for me.

Yeah, I hate it.

But I hate it more to leave my mission halfway through.

Suit yourself.

Well?

I went back through the security camera footage near the dam

and found a face I recognized from the employee list of Keikoku Corp.

This woman...

Wakabayashi Akari-san, am I right?

We're from DCU of the Coast Guard.

Hello.

A month ago?

Yes. I think I went there.

- What for? - Visiting a colleague's place.

And who is it?

The owner of a kamameshi restaurant.

Kamameshi?

This is Noda Shokudo, a long-established kamameshi restaurant near the Hashibe Dam.

The old restaurant went down in the dam and now he's operating a new one.

He's the kamameshi seller who frequented the prefectural police.

He had an only son.

His name is Noda Hiromasa, a former employee of Keikoku Corp.

He was Wakabayashi Akari's ex-fiance.

"Ex"?

Noda Hiromasa disappeared in Russia five years ago.

Disappeared in Russia?

He was found to have spent the company's fund,

escaped on a business trip to Russia,

and his whereabouts are still unknown.

That's fishy.

Takako and I, Nishino and Seno will split up.

Try to find the connection between this man, Wakabayashi, and the murdered Mouri.

Roger!

Whoa! That was superb!

There aren't many restaurants nowadays that bake their own iron pots

in their own kilns, are there?

Thank you.

This was a pottery town before it was dammed.

Yeah, because this area is full of peat.

- Peat? - What is that?

Burnable soil.

In the past, it was often used in stoves instead of coal.

Oh...

You know a lot, sir.

Back then, there were these anagama kilns

for peat all over the town.

Now there's that.

We use the gas kiln.

But the texture and sheen are nice.

I know, right?

It takes a little extra time when baking to make it shiny.

It's always been our authentic item.

I see.

That was delicious.

Thank you very much.

- By the way, sir. - Yes?

You know Wakabayashi Akari-san, don't you?

No, I don't.

We're from the Coast Guard.

We're currently investigating on the dam incident.

How could you not know?

She was engaged to your son.

Five years ago, he disappeared in Russia.

But he may actually contact you from time to time.

Get out of here!

Will you please leave now?

The guy who left his hometown because he didn't want

to take over a kamameshi restaurant in the countryside.

He's no longer my son.

He's none of my business.

Therefore, I have nothing to say.

Excuse me, a table for two.

Welcome.

Did you know anyone who opposed the dam construction?

Of course, because our hometown was sinking.

Were you opposing the dam construction?

Of course I was!

Noda-san's son?

In that case, you should ask the former union president.

Yoshida-san, he's running a gallery.

Gallery?

You told me about the kamameshi restaurant

so I thought of looking into it.

I found out that a certain chemical

is needed to make it shiny.

Dilute hydrochloric acid.

Diluted hydrochloric acid.

I see. All right.

I'll try to find its access route from the kamameshi restaurant.

Counting on you.

Hiromasa-kun came back to his hometown here as a member

of the dam construction project team.

So you're saying that he was the one who dammed up his hometown?

You could say so.

A man who left his hometown because he didn't want to live in the countryside, eh?

Excuse me...

What photo is this?

That's a group photo of the opposition union members at the time.

Why was he here with the opposition?

The Hashibe Dam project started as a national project, but...

When the MLIT approved of it

and concrete construction plans were started,

allegations of embezzlement by President Mouri began to circulate,

sparking opposition from the local people.

Noda was selected for the project team

because he was from the area,

and he was assigned to persuade the locals who opposed the project.

The order was given by President Mouri

and Osanai, the project leader at the time.

No wonder Noda's father is so angry.

But in fact, Noda's son had rejected it.

He wasn't abandoning his hometown, but trying to protect it.

What's more, he was working discreetly with opposing locals

to divulge information from the company.

Unfortunately, since he was supposedly part of the project team,

only a few people in the union knew that he also opposed it.

His father didn't seem to know until the end.

According to the union president,

Noda's son was determined to stop his hometown from sinking,

even if it meant stabbing Mouri and Osanai in the back.

But before he could, his own deceit was unveiled.

He embezzled the company's fund

to support his opposition movement.

So instead of stopping the dam,

he ended up running away himself.

So he's the man whose hometown and life were robbed by Mouri and Osanai.

That's enough motive for revenge.

Noda Hiromasa.

It's possible that he may be back in Japan.

Wakabayashi Akari's call records.

She was in frequent contact with

another phone in her name.

You mean she's letting someone else have it?

That's Noda.

And one more thing.

There was someone with whom Noda went on a business trip to Russia five years ago.

I see you were indeed in San Francisco.

Didn't you investigate to gather the evidence?

I just wanted to confirm it myself.

What's wrong?

Are you perhaps going overseas again?

Yeah.

I'll be in LA next week.

I'm attending a meeting now, so let's make this quick.

Actually, I came to ask you about your business trip to Russia five years ago.

I heard that an employee named Noda who accompanied you at that time, disappeared.

Noda?

I heard he escaped when his deceit was unveiled.

You know it well.

The day we arrived in Russia,

I was informed that he embezzled the fund.

But that fact was never made public. Why?

Management decision.

Even if he didn't, President Mouri's embezzlement scandal

had tarnished our image.

Do you know why Noda returned to Japan?

Returned here?

For example...

He returned here to seek revenge.

All the way from Russia?

Revenge for what, exactly?

You must be joking.

We're now trying to figure out whether it's a joke or not.

Did he perhaps... kill President Mouri?

If that's the case, then you're the next target.

I came to tell you that.

Thank you for coming all the way here.

I'll be careful.

By the way, do you know what makes a war happen?

To protect the homeland where one was born and raised.

The resentment of having one's homeland taken away

is that deep.

I've found their route to the hydrochloric acid.

Really?

Look at this.

The hydrochloric acid that Noda Shokudo used for their iron pots

is always bought from a chemical factory outside the city.

When I checked the security cameras in the area around the factory...

Wakabayashi?

It's the parking lot near the factory.

I asked Ruri to confirm it with the facial recognition system.

And it's undeniably Wakabayashi Akari.

And look at this.

Noda Hiromasa?!

So he really returned here.

He returned to seek revenge.

But how do we catch him?

There was no record of him entering the country,

so he must have smuggled in.

He may have gotten his revenge and already left the country.

No, all their contacts in the last month were domestic calls.

He's probably still in the country.

To avenge one more person.

All right. Please do.

Yeah.

We'll talk about that matter tomorrow.

Oh, yeah.

Like I said, I left that up to you.

Let's hear what you have to say.

With your other fellow.

Run!

Nishino, he's heading your way!

Seno, go around!

Black outfit and black hat!

Roger!

Hey, stop!!

Hold still!

Noda!

Noda...san?

The content of this bottle you were carrying

was water.

I heard on the news that hydrochloric acid was used as the murder weapon, so...

I was going to threaten Osanai with this.

Trust me!

We didn't kill anyone.

We just wanted to ask Osanai.

About Hiro-kun's whereabouts.

What do you mean?

The day before he left for Russia,

Hiro-kun found out a secret about the company.

He said he'd negotiate with Osanai

to stop the dam in exchange.

But Hiromasa-san went missing in Russia.

My son was killed

by Osanai in Russia!

Otherwise, he wouldn't have lost contact for five years.

That's why I became his secretary.

I've spent years looking into what happened back then.

And I finally found the secret he was talking about.

Five years ago,

Osanai made a slush fund transfer to the local union president.

I found out a proof of it.

My son was fighting like hell

to protect our hometown.

When Akari-san told me that,

I wanted to know the truth, even if I should threaten.

He said he wanted to return home one day

and take over my restaurant.

For that reason,

he told Akari-san that he wanted to learn how to bake iron pots.

So that when he's back,

we can run the restaurant together as a family.

It didn't look to me like they were lying.

Who on earth killed Mouri then?

It's probably Osanai, after all.

But Osanai has an alibi.

The following is information about the typhoon.

Leeks?

Yeah, the kamameshi we had the other day was superb, so I tried making it.

That's a lot.

Vinegar also has embalming effect, so it lasts longer.

According to the Japan Meteorological Agency, Typhoon No. 22 is moving

northeastward across the Philippine Sea with increasing strength.

The storm is expected to enter

Kanto-Koshinetsu region as early as midday tomorrow.

The 24-hour rainfall forecast for the day after tomorrow morning

is 200 to 300 millimeters across the Kanto region,

which is an alarming amount of rain...

So, do you have enough evidence to arrest him?

Can I trust you?

If he's falsely accused,

you understand the consequences, right?

We'll surely obtain the evidence.

Why are you asking me to begin with?

Does that mean DCU already waves the white flag?

You're the one who's hostile to us.

And I didn't offer anything for free.

Hello.

You know, I've always been wondering.

The police and our team swept the river, but we didn't find anything.

If the body was dumped in the river,

it's only natural that the bones would be scattered by the time it reached the dam.

Nishino and the guys delved the dam near the river mouth, but they found nothing.

But now I finally understand why.

The body was never dumped in the river to begin with.

Then how do you explain the security cameras at the dam?

It's impossible to dump a body in the blind spot of that many cameras!

The body was deep in the dam the whole time.

And it still is sleeping underwater.

What?

Osanai will leave Japan next week and our time limit is two days.

Tomorrow, after the typhoon passes, we'll dive the dam and search for the body.

In just two days? That's crazy.

Once he leaves the country, he's not coming back.

He'll probably try to flee the country.

That's how far our battle goes.

Captain, it's from Shimizu-san of Public Security.

It's Niina.

I see. All right.

What did he say?

Osanai hastened his departure.

To when?

4 p.m today.

- Today? - We only have half a day left.

There's a typhoon outside and we can't dive until tomorrow.

What do we do?

We'll just start diving now.

In the middle of this typhoon?

Where are we going to dive? We're running out of time!

I've got a plan.

- Kanda. - Yes, sir.

Noda Shokudo? The old one?

This place is 120 meters deep!

- I guess. - It's suicide mission!

I've never heard of diving a 120-meter dam.

Especially during a typhoon.

Still, I'm going to dive.

Who else is joining me?

I'm joining you!

Please let me join you.

All right.

Listen, all of you.

For us DCU, nothing is impossible underwater.

- Please hurry to Haneda. - All right, sir.

Seno, we'll face poor visibility and the current.

Connect the rope at the bottom of the lake.

Yes, sir.

Takako, prepare two spare tanks!

Roger!

Water depth 80 meters.

They're over 100 meters deep!

Water depth 120 meters.

They reached the bottom of the lake!

The sand is moving due to the water discharge.

Must be pretty bad visibility.

I could barely move forward the other day, it's too much!

We're almost at the target.

Is the body really here?

There used to be many kilns all over the town.

According to Captain, the incident took place in one of them.

The point is the hydrochloric acid on the bone.

That's right.

Noda's father was the only one in this town

who used that hydrochloric acid.

And at the bottom of this dam, 120 meters below the surface,

there laid anagama kiln Noda's father owned.

With the remaining bones.

Which means there's a good chance that the body is in there.

You're right, we haven't uncovered that location.

It's 120 meters deep, you know?

Of course we haven't!

Even if we could narrow it down, the visibility would be too poor.

We may not make it in time.

Osanai's departure is in less than an hour!

There's nothing we can do at this point.

There's not much time, we should dive too!

There's no way you can go deep down there!

Don't worry. Let's have faith in them.

I'll have a check.

Osanai is passing through the departure gate.

What are they doing!

What's wrong?

What happened, Seno?

They seem to be fine now.

It's the kiln.

It remains as it was then.

They found it!

Amazing.

The aircraft will soon take off from Tokyo International Airport to Los Angeles...

It's there!

Found it! They found it!

Prepare to pull out now!

Roger!

We're from MPD Public Security Bureau.

Osanai Shoichi-san.

An arrest warrant has been issued for your murder crime.

President Mouri was murdered a month ago, right?

I couldn't possibly murder him.

I was in the U.S.

No.

The murder wasn't committed a month ago.

But five years ago.

What do you mean?

The peat.

Peat?

The burnable soil that was once used to bake the iron pots for kamameshi.

If a body is buried in that soil,

decomposition will not proceed.

Some mummies from B.C. have been found preserved intact for thousands of years.

It's the same logic as soaking the leeks in vinegar.

Leeks?

Peat has the same embalming effect as vinegar.

And since the bottom of the dam was cold with low oxygen

the embalming effect was even greater.

As a result,

a dead body from five years ago was identified to be a month old.

If the murder was committed five years ago,

there wouldn't be any evidence left from such a long time.

Why am I under suspicion?

There's more to it.

The body found at the bottom of the dam

was not President Mouri's.

But Noda Hiromasa-san's body.

Noda-san found out that you made a slush fund transfer to the union president

and you killed him to shut him up.

Am I right?

That's bullshit!

On what basis?

The day before the business trip to Russia,

he had told his fiancée about it.

She even became your secretary to seek for the truth,

and she finally got the proof

of the slush fund.

The place where Noda-san's body was found

was inside a kiln once used by his father.

You murdered Noda-san there.

The visa for business trip to Russia was approved.

Good job!

And what about the cancellation of the dam construction?

About that matter...

We'll talk about it when we get there.

My hometown will sink to the bottom of the water tomorrow!

But I'm not giving up yet.

I'm not going to Russia.

I will disclose your deceit in the dam construction.

"Dilute Hydrochloric Acid"

Five years ago, you were in the middle of the embezzlement scandal.

In order to get President Mouri fled,

you came up with the idea of having Mouri leave the country as Noda-san.

That's the truth behind the business trip to Russia.

The one who forged Noda-san's passport to leave the country...

...was Mouri.

And the cover-up was thorough.

You found out that Noda-san was staying

at an affiliate hotel near Hashibe

and you reported that Mouri was hiding there.

We took DNA sample from that room.

The DNA was registered as belonging to Mouri,

causing DNA of the bones found in the dam was a match for Mouri.

It was nicely done.

That's just allegation!

Even if

you find evidence of the slush fund,

it doesn't prove that I killed him!

You want evidence?

It's still intact.

To this passport of yours that has been ripped open.

So what?

Can you guess what this is?

This is what Noda-san's body was holding.

Preserved by the peat.

It is still in its original form.

If you put these together...

Not only that.

It's only a matter of time before the killer's fingerprints

or DNA are found on the murder weapon left on the body.

After all,

you preserved it in perfect condition,

didn't you?

Osanai-san, what you took wasn't just Noda-san's life.

His love for his hometown and his desire to protect it.

And by dishonoring him,

you've taken hope away from his father and fiancée.

This fragment of paper

showed his tenacity for his hometown.

And his tenacity

defeated you.

Please tell me one thing.

You assured me that you'd obtain the evidence.

Was there any reason you said that?

No, there wasn't.

But I was confident.

The truth is certainly there underwater.

The water never lies.

We've teamed up this time, but there won't be a next time.

I don't want to break into the cold sweat ever again.

And by "not for free,"

do you mean that boy over there?

I'm not sure.

Public Security, let me tell you one thing.

Whether it's police dog or anything,

I'll use it if I have to.

Anything to reach my goals.

I heard you couldn't get your memory back.

What's wrong?

Did you remember something?

What are you talking about?

Whatever you remember,

don't trust that man.

It must be cold.

You did great!

Well done!

Hey, Akari.

One day, let's run kamameshi restaurant at my father's store.

Therefore...

I will!

Welcome home.

Hiro-kun.

You're the one who leaked it?

I gave the credit to Public Security.

This much spill isn't a big deal.

No.

Well done!

We saved the police's face

and we took all the good parts.

It's more than just a spill.

Does that mean I get a passing mark this time?

Yeah, I guess.

But next time, you'll have to report it before you dive.

Although I trust you,

Deputy Director Hayakawa doesn't like the grandstand play.

Very well, sir.

Niina.

If he were still alive,

I'm sure he'd be happy about this impact.

Mr. Deputy Director.

Nishino-kun.

May I have a moment of your time, please?

I'd like to talk to you about Captain Niina.

You're safe now.

Is this what you're looking for?

That key is what Dr. Seno entrusted to me!

Sorry, but I'm going to keep this.

Don't tell me... you're the spy?

What's wrong?

Oh, burglary?

I'm calling the police.

This is the key from that time, right?

It's the key you stole

from my father, isn't it?

Do whatever it takes to achieve your goals.

I think I finally understand what that means.

You framed up your buddy Nariai-san

and drowned your sins to the bottom of the sea.

And you went down in the Coast Guard's records as a hero

who saved a boy from the incident scene.

It's so pathetic I can only laugh.

For 15 years long, I had no idea that the person I thought had saved my life

was the wrong one.

What are you gonna do now?

If you're so frustrated, remember.

Your memory.

Try to remember it.

I will never forgive you.

About my father, Nariai-san, and that key!

I'm going to expose

and reveal everything.

Go ahead and try if you can.

Only if you can.
