Your father was paid handsomely by the terrorists.

That can't be true.

Then see it for yourself...

...with the key.

I got Nariai's tail.

Hot spring facility?

Nariai?

Nagashima Spa Land in Mie?

Most definitely.

This is a photo of Nariai found on a social media three months ago.

This portion in the background matches part of the roller coaster.

A man who was formerly a researcher at Tohto Heavy Industry now works at a neighboring hotel.

He could be in contact with this man.

Is this related to the incident 15 years ago?

I can't say for sure, but we finally got a clue.

Please let me join and investigate with Nishino who is in the area.

Preparations for G20 Maritime Security will soon begin.

How will I explain this to Deputy Director Hayakawa?

Niina, you haven't had honeymoon yet, right?

OK, take your wife there,

I'm sure the deputy director will understand.

Honeymoon?

Here is your room key and spa ticket.

Thank you.

Assist them.

Let me show you the room.

We hope you will enjoy your stay.

Thanks.

Hey, what's with the spa ticket?

This is the least I can do.

No way! Are you serious?

You're too loud!

Sorry!

But it's unlike you!

Something is fishy.

Affair?

Is this an apology trip?

Nothing like that. Should I cancel it?

Just kidding! I'm sorry.

I will gratefully take it.

Sure thing.

Captain and Mako-san are on their honeymoon right now.

Must be nice!

Nice? It's definitely for investigation. An undercover one!

Seriously?

There's no way Nishino-san would go on a business trip at the same time.

Does Seno go too?

He's off today.

Even him?

What on earth are they investigating?

Kanda-san, have you heard anything?

Nope.

"SENO"

Amazing!

I apologize for my haste, but

would you like to have the spa treatment?

There will be an opening right after this.

Why don't you go?

Well, if you insist.

Enjoy!

It's me.

Totsuka Akio, the manager of this hotel.

After retiring from Tohto Heavy Industry 15 years ago,

he was adopted into his wife's family who owns this hotel

and changed his surname to Totsuka so he could take over the business.

He runs the hotel with his daughter.

Do you want to interview him?

I'll ask him directly.

What about Seno?

He's been inside his parents' house for a few hours now.

His parents' house?

Captain.

Was it really safe to give him that key?

Nishino.

This is a gamble.

If Seno is in contact with Nariai, he will make his move.

We'll get closer to Nariai when the time comes.

But what if Seno betrays us?

I told you it's a gamble.

Whoa~ this is happiness!

Manager Totsuka?

May I know what your business is?

I have a personal matter to discuss.

Can you please call him for me?

Sure thing.

I'll check with him now.

"Totsuka Akemi"

You are looking for an old friend?

Yes, a man named Nariai Atsushi.

Nariai-sama?

I'm afraid I don't know.

I thought perhaps he was visiting you.

- Me? - Yes.

Totsuka-san, you used to work at the Marine Research Institute of Tohto Heavy Industry, didn't you?

This man was an acquaintance of the late Dr. Seno.

I heard that you were Dr. Seno's assistant.

I was, but...

That's all in the past.

What kind of person was Dr. Seno?

Not only in his research, but he was also very aggressive

in his personal life.

Aggressive?

He was a sports and music enthusiast,

and when I was working under him, he was very much into swimming.

Swimming?

Actually, we have information that Dr. Seno's research data, which was supposed

to be stored at Tohto Heavy Industry,

was spread to a certain criminal organization through this man.

The person who passed it to him might be someone related to Dr. Seno before his death.

Like you, for example, who was his assistant.

I passed it?

You retired shortly after the accident.

As if you were hiding.

You even changed surname.

It's to take over this hotel.

I have no further answers for you.

May I go now?

I see. Very well.

What were you doing until this late?

My bad.

This is our honeymoon, right?

Well, let me pour you a glass.

You came here for something else, didn't you?

How could you lie in our early marriage?

Isn't there something else

that you're hiding?

Here.

- Thank you for waiting. - Yeah?

Niina-sama, I brought you tea.

Oh, yeah, thanks.

If you've finished your meal,

I would like to spread the futon.

All right, in 10 minutes.

Would you like to try the hot springs?

I thought it closed at 10:00 pm?

If you would like to come, the manager would keep it open.

Come on, since we're here.

You're right. We'd like to.

You can go ahead back to the room when you're done.

Roger!

How did it go?

Not much new informations.

What about the manager?

Let's talk inside.

I'll go ahead.

Nishino...

Nishino!

Hey! Nishino!

Nishino!

Nishino, hang in there! Nishino!

Sir, is everything okay?

- Open the window! - Alright!

Nishino! Nishino!

Nishino.

Captain...

You collapsed in the bathroom.

The manager's daughter who came here took care of it immediately.

When I was in the bathroom,

I started to lose consciousness after a while.

Strong sulfur smell.

There shouldn't be any sulfur in the hot springs here.

Someone intentionally filled the gas.

The target wasn't Nishino, but me.

I guess the culprit thought I would come alone.

Had I not invited Nishino, it'd be me who collapsed.

I'm sorry.

Explain it properly.

First of all, why is Nishino-kun here?

Well...

The possibility that Seno's father was connected to the Black Butterfly has emerged.

A man who used to be his subordinate is in this hotel.

I did a little probing and this happened.

We should call the police.

This is attempted murder.

Hold on. This is undercover investigation.

I can't make a big deal out of this.

First of all, prove this attempted murder.

Unbelievable.

I'm supposed to keep quiet when my husband's life is targeted?

Can you investigate something like this in a casual manner?

I'm gonna get some hot water for now.

When I got around here, I started to suffer more.

Let's check inside just to be sure.

This is...

As I thought, sulfidation.

Sulfidation?

It means that the sulfur and metals in the drainage ditch

reacted chemically and turned black.

Someone put chemicals in here

to vaporize the hydrogen sulfide that filled the bathroom

which caused poisioning.

The hot water is circulated and filtered, so

if you open the window and ventilate, there'll be no trace of it.

The trace...

Hold on!

Stay put, I'll collect it.

Captain.

It's from Kanda.

Seno has started to move.

It's been about 5 minutes since he went inside.

Confirm who he's meeting with.

Okay.

Huh? He's gone.

The GPS hasn't moved a single inch.

I'm sorry. He got us.

Wow, this brings back memories.

They often came here.

No matter how trivial it may seem,

can you tell me anything about my father?

He used to come a lot, but that was a long time ago.

"We accept storing your fishing luggage"

Is that...?

Do you keep any of my father's luggage?

Every once in a while,

a customer like you shows up unexpectedly after 10 years.

Thank you.

Excuse me, may I borrow this?

Thank you very much.

Seems like a wrong guess.

Why are you here?

I don't want the blueprint you've found to be hidden again.

Even if I did find it, I wouldn't give it to a terrorist like you.

Can you trust Niina?

He'd been keeping you from the matter that your father might be a terrorist.

My father was a brilliant scientist.

You have no right to call him a terrorist.

You know about mind control, right?

Huh?

Are your memories real?

What are you talking about?

Even if someone had falsified your memory to suit their needs,

you wouldn't realize it.

Are you saying my memories are a lie?

It could be if Niina embedded it as he pleased.

Stop the bullshit!

What did Captain do to deserve such a nonsense from a terrorist like you?

Then what about the GPS that was attached to your phone?

You were being surveilled by someone you trusted.

Apparently your relationship is a one-way sentiment.

You would never realize it if I hadn't told you.

Let me tell you one more thing.

Niina is currently in Kuwana City of Mie.

Kuwana?

Trust me.

Get your true memories back.

But you must first...

...find the blueprint.

Are your memories real?

I'm the only one in yellow.

I actually could swim better.

I just had a cold on the test day.

All right. I will give you a test!

Ready, start!

Keep going!

Great.

Give it your all!

Almost there.

It's here, Haruki!

Well done!

Good job, you passed!

Look what you've got.

I knew this would suit you.

Take care of this.

I think we can get results in the evening.

I'm sorry.

I'll make it up to you, I promise.

Make up for what?

Listen.

I just want to say one thing.

I have had enough of losing people I care about.

I'm sorry.

He noticed our movement.

Where did that guy go after leaving his phone?

Check the incoming call logs.

Several missed calls came up.

He was certainly the one who was getting calls.

I see.

What are you doing?

Why are you here?

The same goes to you.

Honeymoon.

I heard Mako-san is at the Coast Guard, though.

Keeping silent?

So you're gonna hide it again?

It's a basic rule to keep silent about investigations, right?

Nevermind.

Can I ask you something?

You taught me to swim when I was lonely and orphaned.

You gave me the dream of becoming a Coast Guard officer.

Why did you?

Is it because you wanted to overwrite my memories to prevent me from remembering things

that were inconvenient to you?

I taught you how to swim.

You worked so hard to learn it.

No more and no less.

You can't convince me with that!

If you're gonna face the past, compose yourself.

Then you will know what you need to do, regardless the outcomes.

It's a good chance.

Now that I gave you back the key.

Let's not meddle in each other's affairs any more,

shall we?

Good idea.

I will also face myself calmly.

It was sulfide as we guessed.

Is that so?

I also checked the footprints,

and they match the ones worn by the hotel's female employees.

When her father left Tohto Heavy Industry, Akemi was 8 years old.

They moved into her mother's family

to help managing the hotel.

When she was in middle school, her mother died of illness.

After graduating high school, she went to a local university.

With rough science knowledge,

she can easily come up with a way to make it look like an accident

by using the hydrogen sulfide.

Also, she is getting married next month to a classmate from school.

Where is your daughter? I haven't seen her.

I think she is resting because she is feeling sick.

In that case, I don't mind talking to you.

I want to talk about your daughter.

In regards to my subordinate collapsing in the bathroom last night.

Please wait in the dining room on the first floor.

I will be there as soon as the customer is taken care of.

All right.

Hydrogen sulfide?

I have no idea what you are talking about...

Are you sure?

Actually, I thought for sure it was you who did it.

Knowing that I'm probing into that man.

No way... Please don't joke.

If so, was it your daughter?

When I tried talking to her, she disappeared as if she was running away.

I hear she is getting married next month.

I see.

Did you think I would destroy the happiness before you?

Enough said.

Oh, I'm sorry.

I suddenly got upset.

Totsuka-san, it's done.

If you would like.

Our local specialty, orient clams.

I hope it suits your taste.

I'll bring you beer.

I understand your concern.

I'll take this side then.

All right, I will take it.

You know, I'm a sucker for seafood.

Yeah, he is sleeping now.

Don't worry. It will work this time.

But... will this really...

...protect my family?

All right.

How does it feel to take sleeping pills you put in yourself?

Anticipating what I'm wary of,

you dared to put sleeping pills on your side.

But I switched it around.

I understand your concern.

I'll take this side then.

Yeah, he is sleeping now.

Don't worry. It will work this time.

But... will this really...

...protect my family?

All right.

While you were asleep, I checked the source of the call.

Unfortunately, I couldn't identify it.

But I do know that there was someone behind you.

You tried to kill me twice.

But you failed because

there was someone who tried to stop your plan.

It was your daughter.

She told me everything.

I am sorry for doing this.

There are no security cameras here.

I can talk to you without my father knowing.

After that man came, my father was acting strange.

Was it this man?

Yes.

My father always seemed to be scared of something.

And then you came.

When I saw my father inviting you to the bathhouse,

I knew something was going on.

Sure enough, my father did something.

And I rushed to turn off the hot water.

She also told me about the sleeping pills.

She said you hid it in your desk.

I'm sure my father is going to use it

to kill you again.

I'm asking you.

Before my father commits the crime,

could you please leave the hotel?

She said so, but I saw it as a chance to find out the truth

and took advantage of it.

You were threatened, and you tried to kill me for your daughter.

But she saved my life for you.

That is the truth.

I wanted to let her have a happy marriage.

And yet...

I made her the daughter of a criminal.

Totsuka-san, I won't arrest you.

What...?

In exchange,

I'd like to hear what you know.

Why did that man come to you?

The blueprint.

The man came to ask about the blueprint

for the remote system that Dr. Seno was working on.

Remote system?

Hijack a tanker ship with a single phone.

The system is capable of

causing a ship collision

or blowing up a city at any desired location.

The man said that the current blueprint

which was originally stored at Tohto Heavy Industry, is incomplete.

The doctor had the completed version

locked somewhere.

That's why the man wants to know the place.

Fifteen years ago, there were rumors that

someone in the company

was passing the technology to overseas terrorist organization.

And Dr. Seno was suspected.

But the truth was the opposite.

He realized that upper management was diverting technology

and was going alone to fight against it.

I'm leaving the company

and will press charges against this matter.

Doctor...

You also have a child, don't you?

Can you tell your child that you're making tools to kill people?

Yamamoto, join me to leave this company.

I was ordered to steal the complete version of the Doctor's data.

However... I couldn't do it.

But a few days later, he was killed in an accident.

That made me scared.

And then I entered my wife's family.

That was how I took over this hotel.

That should have been the end of it.

However, three months ago.

That man showed up.

Totsuka-san.

Thank you for telling me.

Niina-san.

After all, I want to atone for my sins...

Your daughter...

Give her a wonderful wedding.

Ready, start!

Keep going!

Give it your all!

Well done!

You passed.

It suits you well!

I'm the only one in yellow.

I actually could swim better.

I just had a cold on the test day.

All right.

I will give you a test now!

Ready, start!

Give it your all!

Great!

Go, Haruki!

Wider!

Dad...

Haruki, listen.

There may come a time when I have to give you this key.

I'll keep something very precious in your treasure chest.

So when the time comes,

give it to the person you trust the most.

You got it?

Yeah.

That's my son.

Haruki, you hear me?

Give it to the person you trust the most.

Trust me.

Where did you find it?

In a place of memories with my father.

Did you finally remember?

Yes.

Just a fragment of it, though.

Well done.

I will keep it responsibly.

What's the matter?

Can I trust you?

I promise.

The data will no longer exist in this world.

Don't you worry.

It's me.

The usual place at Yamashita Pier.

Nariai, long time no see.

I'm surprised you could find this place.

The only place seen from that rooftop where you can go out to sea

is here.

I'm impressed.

If you're alive, why didn't you show yourself to me?

Or... couldn't you?

I got what I wanted.

Seno-kun entrusted it to me.

Not to you, but to me.

You made him do it, didn't you?

With a bunch of lies.

Nariai, what the hell happened?

Black Butterfly?

It's my win.

Captain! Are you okay?

Yeah.

Arrange for emergency deployment!

- All right! - It's pointless!

He's probably meeting up with his fellows by now.

He is...

A member of Black Butterfly.

All the more reason to take it back!

Let's hurry!

The blueprint is hazardous, isn't it?

That is a fake one.

What do you mean?

Are... your memories back?

Yes.

The real one

is this.

The one who gave me the dream of becoming a Coast Guard officer is you, Captain.

I swam 50 meters.

I was the first in class!

Thanks to you, uncle!

No.

You used to be able to swim.

You were afraid of the water for a little while,

and all I did was get you back on track.

Haru, do your best.

Uncle!

I want to be like you!

I want to be a person who rescues people in the sea.

In that case...

You need to practice more.

I will!

Until now, I doubted you.

And said horrible things to you.

I am so sorry.

"This folder is empty."

Please tell Dr. Seno's son

that his father was a wonderful man who never gave in to any evil.

Totsuka-san, tell me one last thing.

Who instructed you to steal Dr. Seno's data 15 years ago?

It was an order from President Narahara of Tohto Heavy Industry.

The President of Tohto Heavy Industry?

Niina-san, actually...

The one who ordered me to kill you

wasn't Nariai-san who visited me the other day.

Then who was on the phone at the time?

He just entered now.

He was Dr. Seno's assistant

and my superior at the time.

I'm from Marine Research Institute of Tohto Heavy Industry,

Kasahara.

Yeah.

You're home?

Welcome back.

Is it over?

Yeah, for now.

You must be hungry.

I'll make you something.

Yeah, please.

It's my phone.

What is this...

"Nariai Atsushi is alive."

No way...
