This settles Hikari-chan's illness.
It's spontaneous occlusion of the Circle of Willis.
Moyamoya disease.
Since it's neurosurgery,
you're the expert, but...
I'll do it.
The reason you haven't been operating
is because of your hallucinations, right?
And now suddenly you'll operate?
What on earth happened with Hikari-chan?
Do you remember
the bombing incident 2 years ago?
Mao and I were there.
And so was Hikari-chan.
Treat that girl before me.
She'll die if she's left alone.
Save her.
Hikari-chan lived on in place of Mao.
If I let Hikari-chan die,
Mao will have died for nothing.
Tachibana-sensei hasn't come in yet.
That's odd.
Tachibana-sensei, can you hear me?
Blood pressure 150, pulse 90,
saturation 99.
Emergency blood drawing.
Glucose and thymine.
Biochemical blood count, please.
How is she?
She's unconscious.
We don't know the cause.
Level 100, no pupil reaction.
Let's do a CT scan.
How's Hikari-chan?
Nitta-sensei will operate in place of Tachibana-sensei.
Since there's no time to delay.
That's true.
For now, get Tachibana-sensei to the CT room.
The stretcher's here.
This is bad.
The surface blood vessels are very thin.
The 0.3mm level.
They're not usually thick enough to show in angiography,
but these are exceptionally narrow.
The walls of the blood vessels will be very fragile.
They'll break if touched wrongly.
Direct bypass is impossible.
- What shall we do? - We have no choice.
We'll have to do an indirect bypass.
Okay.
Metzenbaum.
Regarding Fujiwara Hikari-chan's direct bypass surgery,
I confirmed the operative field
but the blood vessels are extremely thin and vulnerable
so I couldn't touch them.
I switched to indirect bypass surgery,
but that's just a stopgap.
We'll have to consider moving her to another hospital.
I don't know if anywhere will take her, though.
I can't do it, but Tachibana-sensei could.
Tachibana-sensei?
She's in no condition to operate.
Tachibana-sensei's brain images.
She has a cerebral aneurysm.
It happens when weakness in the arterial wall
causes an artery to become bloated.
There's a 15mm aneurysm on the basilar top,
where the basilar artery flows along the brain stem.
It's pretty big.
And what a place for it.
It can't have happened overnight.
I wonder if Tachibana-sensei was aware of it.
If she'd known, she'd have had it treated.
Does that mean she had no symptoms?
Then when on earth did it happen?
Probably 2 years ago.
Director Kitabatake.
The trauma from that time may have caused it.
It's a traumatic brain aneurysm?
In a vessel so deep in the head...
You knew?
You knew Tachibana-sensei had a cerebral aneurysm?
No, I didn't know.
But it makes sense that it would be from that incident.
What incident?
The bombing at Mitsui Movement Square.
There were lots of casualties there.
It got a lot of attention, since it was imitating terrorism.
Does that mean...?
Tachibana-sensei was caught up in it.
That incident took Mao-chan from her,
and changed her life dramatically.
The day of the bombing
was Mao-chan's 10th birthday.
Happy birthday, 10-year-old.
- Thanks. - You're welcome.
It's so cute!
Glad you like it.
Mao!
Mao! No!
Mao! It can't be! Mao!
Save Mao!
MAO~!
They were a two-person family,
so Tachibana-sensei raised Mao-chan with all the love she had.
She couldn't endure a life without Mao-chan,
so she resigned from the hospital she worked at
and hid away at home alone.
She cut herself off completely from the outside world.
On the odd occasion I met her,
she was like an empty shell.
She blamed herself for Mao-chan's death.
That continued for about 6 months,
and then she called me out of the blue.
She said she wanted to work as a doctor again.
I don't know what had happened,
but she was back to her old self.
I introduced her to West Tōkyō General Hospital.
We decided to hide the truth from the people around her.
We said she'd been overseas for 6 months training.
That's why no one at West Tōkyō General Hospital knew.
About Tachibana-sensei's past,
or which overseas hospital she'd been to.
But how did she recover like that?
That I don't know.
How she got her spirit back
is a mystery.
Hallucinations.
Tachibana-sensei has been having hallucinations of Mao-chan.
She's fully aware they're hallucinations.
She says she needs them.
So she's living with a hallucination of Mao-chan?
Hallucinations of her daughter
helped her emotionally recover.
That's why she was able to return as a doctor.
That's why when she came to A&D,
she made it a condition that she didn't operate.
With the hallucinations,
I wonder if she's begun to see things other than Mao-chan.
Things other than Mao-chan?
If she only saw Mao-chan,
she should have been fine.
The fact that she isn't
could mean there's another cause.
Something to impede her medical work.
I'm the one who kept her from resigning as a doctor.
She planned to operate on Hikari-chan like that?
She'd been avoiding surgery until then.
That's because Hikari-chan was there,
at the bombing 2 years ago.
Hikari-chan was?
After the explosion,
when Tachibana-sensei tried to treat Mao-chan's injuries,
Mao-chan said that before her
she should help Hikari-chan
who had fallen nearby.
Is that why Mao-chan...?
That's why Tachibana-sensei...
If we don't do it we won't know the truth!
I have to save Hikari-chan.
For Mao's sake, too.
She was desperate to heal Hikari-chan.
So that's why she decided to pick up a scalpel again.
For better or worse, Tachibana-sensei
has had her life ruled by hallucinations.
The cause of the hallucinations
is probably the cerebral aneurysm.
This is...
It's putting pressure on the cerebral peduncle here.
Peduncle hallucinosis.
A disease where the person is aware they're hallucinating.
Tachibana-sensei is a superb neurosurgeon.
When the hallucinations began,
she must have realised she had a cerebral aneurysm.
But the hallucinations let her continue seeing Mao-chan,
so she didn't seek treatment.
As it deteriorates it may burst.
She knows there's a high chance it'll be fatal.
You mean she's prepared to die?
That's how much she loved her daughter.
If Tachibana-sensei is to do Hikari-chan's surgery,
the aneurysm must be removed first.
Otherwise she might hallucinate during the operation.
But if it's removed,
she'll stop hallucinating Mao-chan.
Then what should we do?
We have to let Tachibana-sensei decide.
- Any alternatives? - As things stand,
all we can do is speak to Tachibana-sensei.
Given Hikari-chan's situation and Tachibana-sensei's,
only Tachibana-sensei can do Hikari-chan's surgery.
For that to happen,
the cerebral aneurysm must be removed.

Finale
Why are you coming with me?
Tachibana-sensei is a mentor to me.
Oh? And I'm not?
No, it's only natural I would respect you.
There's no right choice, is there?
Between Tachibana-sensei and Iwakura-sensei?
No, I mean Tachibana-sensei's decision.
That's true.
There may not be a correct answer.
Tachibana-sensei, what are you doing?
Oh, good morning, Iwakura-sensei.
Tamaru-sensei, Nitta-sensei.
Shouldn't you be in bed?
I'm feeling better, so I thought I'd get back to work.
How's Hikari-chan?
I tried to operate in your place,
but the blood vessels were too thin
so I couldn't do direct bypass surgery.
I covered as best I could with an indirect bypass.
That's not a long-term solution.
No.
A direct bypass is essential.
Fine, let's try that.
- Let's prepare to operate. - No.
I can't allow that.
Iwakura-sensei?
Tachibana-sensei,
you have a cerebral aneurysm.
It's putting pressure on the cerebral peduncle
and causing hallucinations.
You told them?
Yes.
That's why you've been refusing to operate, isn't it?
That's certainly true,
but I have to do Hikari-chan's surgery.
I have no choice.
If you collapsed during surgery,
what would happen to Hikari-chan?
You've seen hallucinations other than Mao-chan, haven't you?
Things you didn't want to see.
You can't control the hallucinations.
If you're to be Hikari-chan's surgeon,
we have to remove the aneurysm.
If the aneurysm is removed,
you'll lose the peduncle hallucinosis
that's causing the hallucinations.
If you keep the hallucinations,
I can't let you do the surgery.
Will you give up your hallucinations of Mao-chan to save Hikari-chan?
Will you give up on operating on Hikari-chan
and keep Mao-chan's hallucinations.
You have to make a choice.
Tamaru-sensei, Nitta-sensei,
could you go and check on Hikari-chan?
What?
Fine.
Tamaru-sensei.
Ah, yes.
What I'm about to say
is purely my personal viewpoint.
Is that alright?
I have a child of my own.
That's why,
when I think of what it would be like to lose that child,
it feels like my heart will break.
Right now, you have Mao-chan by your side.
If that lets you live happily...
...perhaps it's fine to go on this way.
There's no need to lose her twice.
To suffer that loss again...
...would be too painful.
I can ask Chief Secretary Sasaki
to find another hospital that will take Hikari-chan.
Consider your decision carefully,
so you'll have no regrets.
Nitta-sensei, what do you think?
Which will Tachibana-sensei choose?
What do you think?
It's a doctor's duty to save the patient in front of them,
but I don't think that means you should sacrifice yourself.
Before being doctors, we're human beings.
We all have things we feel we can't give up.
But because we're human we need to move forward.
To look to the future and not be bound to the past.
Nitta-sensei, Tamaru-sensei!
Hikari-chan's condition suddenly changed!
I'll raise your arm.
What's happened?
Hemiplegia has occurred.
She's fully conscious.
Any hyperventilation?
I don't think so, it developed suddenly.
Blood pressure is 162/87.
Change the monitor and take her to CT.
I'll check for cerebral haemorrhage.
We'll move the bed.
Hikari-chan, we're going to test you.
Hikari-chan's hemiplegia was caused by cerebral ischemia.
We gave an infusion of platelet aggregation inhibitor
and symptoms disappeared.
This time it was a transient ischemic attack,
but it's only a matter of time
before cerebral infarction or haemorrhage.
It's getting dangerous.
Has a hospital been found that will take her?
I'm afraid not.
At least for now,
we have to do what we can here.
She needs surgery urgently.
Has Tachibana-sensei decided?
Not yet.
We don't have much time.
I know.
For the time being,
let's focus on keeping Hikari-chan stable.
- Yes. - Yes.
Here you go, Tachibana-sensei.
Thank you.
How's Hikari-chan?
Her condition worsened for a while,
but she's stable for now.
Don't worry.
But Tamaru-sensei said she needs urgent surgery...
Hey!
Let's go.
Tachibana-sensei, please call us if you need anything.
Um... Sorry.
The only place that has said they'll take Hikari-chan
is in Kansai.
Kansai...
It's Rakuhoku Neurosurgical Centre in Kyōto.
The centre head Katsuragi-sensei responded personally.
I see.
Understood.
If she's to be transferred,
we should make the arrangements immediately.
If Tachibana can't make a decision tomorrow,
we'll contact Katsuragi-sensei.
Okay.
You're very worried, aren't you?
That's right.
I thought you'd come here.
You called me here yourself.
I know.
You see?
Sit down.
You're always with me, aren't you?
Because I'm your daughter.
- Itadakimasu. - Itadakimasu.
You've always been by my side,
helping me.
After you died,
even though I lost the will to live,
you saved me.
After the incident,
when about 6 months had passed,
I went and looked at your room
and found an overdue library book.
It was like I'd found a trace of your life.
I was so happy.
I went outside for the first time in ages,
planning to return the book.
After your death,
I had withdrawn from the world for a long time.
I'm sorry it's so late.
Wait a moment, please.
At that moment...
Are you alright?
What's wrong?
That person looks in pain.
Maybe he's not well?
Mao?
Are you Mao?
What's wrong?
Are you really Mao?
That's right.
What are you saying?
That hurts! Let go.
Mao...
You should help that man.
Someone is suffering.
You have to help.
But I gave up being a doctor...
You should go back to it.
The ability to save people is something special.
Right?
By chance, someone there had a heart attack,
and I saw your image.
And you told me I should save him.
Your words gave me the push I needed.
If I could make you happy by helping people,
I decided I'd go back to being a doctor.
Ever since you appeared before me on that day,
I've continued as a doctor for your sake.
And now Hikari-chan has come as a patient.
The Hikari-chan you saved,
at the explosion site 2 years ago.
The girl you sacrificed yourself to save...
Treat that girl before me.
She'll die if she's left alone.
Save her.
Are you alright?
I'll be back soon.
I sometimes wonder
what would have happened if I'd treated you first.
You might still be...
You can't know for sure.
We might both have been lost.
But you saved Hikari-chan.
That's the only reality we have.
There's nothing wrong with that.
Mao...
Have your aneurysm taken away.
And do Hikari-chan's surgery.
Save Hikari-chan again.
Okay?
Hikari-chan is suffering.
She's suffering because she's fully alive.
Hikari-chan is really here.
Unlike me.
I'm a hallucination.
Everything I say and do is a hallucination.
Even saying this now.
Whether the aneurysm is removed or not,
I haven't been here from the start.
You know that, don't you?
I know.
I do know that.
Are you really that afraid of me disappearing?
Is it that important to see me?
I'll always be with you.
Now and forever.
But...
If the aneurysm is removed...
I'm not in the aneurysm.
I'm in here.
Not as a hallucination,
the real me will always be here.
Someone is suffering.
You have to help.
Save the life in front of you.
Mao...
You're right.
It won't mean you're really gone.
You'll be in my heart forever.
Someone is suffering.
I have to help.
I'll have the aneurysm removed.
I'll save Hikari-chan.
Mao.
Thank you.
Mama.
Mama, I love you.
I love you too, Mao.
Hikari-chan has had temporary left hemiplegia again.
She recovered after 5 minutes, but...
We administered a platelet aggregation inhibitor,
but the attacks are recurring.
We've reached the limit.
Let's prepare to send her to Kyōto.
Nitta-sensei, explain the situation to her parents.
Are you sure about this, Iwakura-sensei?
Ah, Tachibana-sensei.
Tachibana-sensei...
Remove my aneurysm, please.
This is your decision?
Yes.
You're sure you won't regret it?
Yes.
Nitta-sensei.
Yes.
- Do my surgery, please. - Yes.
I will definitely save Hikari-chan.
Contact Katsuragi-sensei, please.
Say we'll do the operation here.
Okay.
Alright, everyone?
Once Tachibana-sensei's aneurysm is removed,
protect Hikari-chan's life
until she can perform the surgery.
- Yes. - Yes.
- No change. - Okay.
Let's go to 3 hours.
Hikari-chan?
She's unconscious.
You're going to do Tachibana-sensei's surgery?
You always hear things quickly.
Those kid nurses told me.
Listen,
did you come all this way to say that?
No, not at all.
Don't worry.
I'm sure you'll succeed.
I know.
I know you can do it.
That's what I came to say.
Bye then.
Takasugi-sensei.
Thank you.
Regarding your decision...
How should I put it?
As your comrade in A&D I'm proud of you.
"Comrade"!
What?
Tachibana-sensei, you're a paragon of a doctor.
I put my heart into knitting this.
- Please use it! - Oh, thank you.
She doesn't need a thing like that!
It's a 15mm aneurysm.
She won't even need hair removed.
- Eh? Really?! - I'll use it.
Tachibana-sensei, next time I arrange a group date
let me know your type.
I get it.
You're all so funny.
- If you would. - Yes.
It's almost time.
Nitta-sensei,
I'm counting on you.
- Tachibana-sensei... - Hm?
When I was still an intern,
I saw you operate just once.
- Me? - Yes.
Your speed and accuracy
were a level above anything I'd seen before.
From that day on,
I aimed to become as good a surgeon as you.
That's why, when you came to this hospital
I was shocked.
You must have been disappointed
when I said I wouldn't operate.
No...
You've taught me more important things.
What a thing to say!
In order for you to pick up a scalpel again,
I will operate perfectly.
Tachibana-sensei.
Hey, why are you crying?
The operation's about to start!
I'm sure that Mao-chan
would support your decision.
From now on, please think of me as your daughter.
I don't think I will.
Thank you, Tamaru-sensei.
I can feel the love of everyone in A&D.
I'm glad I came here.
Let's begin.
We will now remove
a cerebral aneurysm on the basilar top.
We'll use a combination of steroids
to reduce swelling in the brain.
- Yes. - Yes.
Beginning anaesthesia.
Anaesthesia okay.
Intubate, please.
Tachibana-sensei?
What a relief.
The surgery was successful.
The aneurysm was removed.
How's Hikari-chan?
We've used an anticoagulant preparation
to give you time to recover.
She's in a stable condition.
The whole thing was removed.
Does your head hurt?
A bit.
But I'm fine.
For now, focus on recovering.
Yes.
One Week Later
Tamaru-sensei!
Ah, Miyabe-san.
How's Tachibana-sensei now?
It's a week since her surgery, right?
There are no problems with the treatment,
and no sign of complications.
For now, we can relax.
I see. That's great.
We have to celebrate.
How about having lunch together?
Sorry, I have work to do.
Don't be like that.
How about dinner?
I've found a delicious Genghis Khan restaurant.
How about it?
Everything seems fine.
Yes.
Well then...
Let's do Hikari-chan's operation tomorrow.
Yes.
Tachibana-sensei...
Hikari-chan.
I'll be the surgeon for your operation tomorrow.
Let's do our best.
Hikari-chan...
That scar on your back
is from the bombing 2 years ago, isn't it?
How did you know?
Because I was there, too.
You were?
With my daughter.
Your daughter.
Treat that girl before me.
She'll die if she's left alone.
Save her.
Are you alright?
I'll take you to an ambulance.
It was you who helped me back then?
That's right.
I sort of thought it might be.
Oh?
The other girl there was your daughter?
That's right, her name's Mao.
Mao-chan.
She's the same age as you.
How is Mao-chan?
She's fine.
So we have to get you well, too.
I will definitely heal you.
Mm.
Let's promise to do our best.
Cross my heart and hope to die...
Bipolar.
- Thanks for waiting. - Everything's ready.
Nitta-sensei, Tamaru-sensei, let's do this.
Yes.
Let's work hard together.
The rest of you, too.
Let's work together.
Well then, let's begin.
Scalpel.
Suction.
Gauze.
Hikari-chan.
The operation was successful.
You'll be better soon.
- Tachibana-sensei. - Hm?
During the surgery, I had a dream.
Oh? What kind of dream?
About the bombing 2 years ago.
When I was injured and dazed,
Mao was encouraging me all the time.
Hang in there.
My mama will definitely save you.
My mama's a doctor,
and she can heal any illness or injury.
Mama told me.
Her role in life is to help anyone who's suffering.
She'll definitely save you.
"She'll definitely save you", she said.
So Mao said that...
Mm.
Not as a hallucination,
the real me will always be here.
Someone is suffering.
You have to help.
That girl is always encouraging someone.
Huh?
It's nothing.
You've done well.
Ah, hello.
Hello.
I hear Fujiwara Hikari-chan was discharged safely.
Yes.
You saved a future world-renowned pianist.
That's right.
Pay us a bonus for once.
Sorry, the hospital's in the red.
That's the director's fault.
How about Analysis and Diagnosis?
This hospital doesn't need it, does it?
That's right.
A whole team diagnosing each patient.
It limits how many patients we can see each day.
It's a terrible waste of money.
But that's fine.
Think of it as our poster department.
We should think about advertising on TV.
Impressive, Iwakura-sensei.
You have a flexible mind.
Naturally.
I'm considering resigning as hospital director.
- Resigning? - Yes.
A&D is finally on track.
I'll let a new director take over
to manage the deficit
and take the hospital in a new direction.
Will you do it, Iwakura-sensei?
I've already got the Board's approval.
- I decline. - Pardon?
You should carry on yourself.
I want to attract attention as the head of A&D.
I don't want to clean up your mess.
I've got some good coverage planned.
Is that so?
I thought for sure you'd accept it.
No thanks.
Iwakura-sensei...
Do you like wine?
We could get a drink.
I don't have time for that.
The patient is a 57-year-old woman.
She's had severe vomiting since 3 days ago
and has a rash on her abdomen.
Vomiting and abdominal rash.
She has severe gastrointestinal dilation.
There's no sign of what's causing the dilation.
What's going on?
Maybe it's outside, not inside?
What was that for?
Nothing.
The abdominal rash is only on one side?
Yes, the left side.
I know what it is.
The gastrointestinal dilation
isn't caused by anything internal.
It's Ogilvie syndrome caused by the herpes zoster virus.
Paralysis of the nerves that go to the digestive tract?
The rash is only on one side.
That's the proof.
I see.
- Tamaru-sensei. - Yes.
I have a favour to ask.
I will definitely save her.
