Tomomi, being a princess suits you.
I should've been one too.
Being a zombie suits you.
Not sure how to take that.
Tomomi, you dressed the same as me.
Sorry.
No fair, she's ruined it.
You should follow Rie's example.
You'd make a better zombie.
What does that mean?!
She looks the part already?
Yeah.
I'm Rie the zombie.
Nice follow through.
You're both princesses, but totally different.
Obviously! Don't compare us.
Awesome!
- You're a great singer. - Whoa!
This mango pudding's gorgeous!
Seriously?
It's almost time to go.
Seriously?
Rie, have you got the fake blood?
- Natch. - Yes.
- Awesome. - Just going to the toilet first.
- Is this doria? - It is.
You're eating it all?
Well no one else is!
It looks totally real!
- That mouth is incredible. - Right?
At Halloween you've gotta have blood, whatever the costume.
It looks scarily real.
- Let's take a photo. - Oh yeah, let's.
Here goes...
Ready...
What's wrong, Rie?
Rie! Rie?
Rie?
Rie...
What's going on?
We've come from Analysis and Diagnosis to help.
Satomi-sensei, Nitta-sensei, thanks.
- Wow, what a scene. - What's the situation?
Convulsions and vomiting.
Poor level of consciousness.
Onset in a group.
Symptoms of food poisoning.
That's probably it.
We're putting them on drips so they don't dehydrate.
Okay.
I'm just going to touch.
Excuse me.
- Vomiting blood? - It's fake blood.
Confusing...
Is this all the patients?
Ah, no, there's just one with no symptoms.
- Just one? - Yes.
Sensei!
- What's wrong? - Her face...
Coming out in hives.
I'll touch your face.
- Airway closure. - Nitta-sensei!
Cannula.
Laryngeal edema.
I'll do a cricothyrotomy.
- Get things ready. - Okay.
Disinfecting.
Knife.
How's my daughter?
- What's going on? - Tell us!
Please calm down.
I've been told it's food poisoning.
- Food poisoning? - Yes.
They should be able to go home tonight.
I don't think that will be possible.
It's not ordinary food poisoning.
Are you getting used to your new hospital?
Mm, pretty much.
You mustn't cause trouble for the people around you.
Don't worry.
I'm the type who values harmony.
Careful!
Another hallucination?
Let's go.
Six high school girls were admitted for emergency care last night.
Food poisoning was suspected,
but one patient had different symptoms
so we have to consider other conditions.
- Different symptoms? - Hives.
And the other girls?
Only symptoms of food poisoning.
But there may be others later.
So they may still develop others?
It may be infection rather than food poisoning.
Collective airborne infection?
Five people collapsed at the same time.
We have to consider that.
But there's also one girl with no symptoms.
She's been hospitalised as a precaution.
What does that mean?
With an airborne infection, she should have symptoms too.
Maybe they took illegal drugs?
That's true.
Drugs can cause a wide range of symptoms.
Nausea, dizziness, hives,
it fits everything here.
But they're still in high school.
Surely it can't be...
Children these days are incorrigible.
They're frighteningly blasé about crime.
With drugs,
stimulants, heroin, cocaine, cannabis,
MDMA and synthetic cannabis can be considered dangerous.
Mm, let's explore that avenue.
Uematsu-sensei, prepare for drug testing.
Wait a minute...
Aren't you just assuming young people lately are all bad?
What?
There must be another possibility.
What else is there? Tell us.
- Well... - There's nothing, right?
You're just an intern.
Murakami-sensei, Uematsu-sensei, let's go.
Tachibana-sensei~
What do you think?
Well...
The symptoms are all over the place, so it's hard to say.
Aww~
How about you, Nitta-sensei?
I'll think about it when the drug test results are through.
Nitta-sensei never changes.
She only trusts her own judgement.
That's why she clashes with people.
- What? - Nothing.
Well, for now let's speak to the girl with no symptoms.
Okay.
Tomomi-chan,
can you tell us where everyone went at Halloween?
Yes. Let's see...
After school finished,
we gathered at the game centre by the station
and went to karaoke there.
Karaoke at the game centre.
Killing time before nightfall.
We changed into our costumes,
and did our make-up.
And at karaoke we had food.
After that you hit the streets.
Were you all together the whole time?
Yes.
No one left in the middle?
No, no one.
Hey...
How is everyone?
Are they okay?
You must be worried.
We're good friends, always together.
Please, help everyone.
Medical Team
Lady da Vinci's Diagnosis
Subtitles by Candylemon
Tomomi-chan's a good girl.
Concerned for her friends.
She's probably worried she might be infected.
I wish I had friends like that.
Ah, I'll go and investigate the game centre.
Please do.
Tachibana-sensei, we'll go to karaoke.
- You go. - What?
I'll leave that to you.
Ah, wait...
Ugh~
Tamaru-sensei!
Well well~ I was just thinking about you.
What a coincidence.
Ah, sorry, sorry, sorry...
All finished.
Fujimoto-san, do you have a girlfriend?
Me?
I'm into older men.
Wow, get in there.
You are patients,
so please keep quiet.
Okay~
What's your problem, obasan?
Obasan!
Obasan?
There's nothing wrong with them.
Looks like yesterday's treatment worked.
They've been like this since morning.
- How is she? - She's stable.
I've disconnected the tracheal cannula.
The hives cover the whole body?
Yes.
Tachibana-sensei, what do you think?
Don't you have a different diagnosis to the others?
Me?
- You have different ideas... - I'm not that different.
He would've died if he'd gone on that way.
Tachibana-sensei.
Ah~ Hello.
I here you have six high school girls in?
- Yes. - How wonderful.
A garden of women.
So, what do the team think?
Iwakura-sensei suspects drug use.
Satomi-sensei believes it's an infection.
And you?
I'm not sure yet.
I see.
Equally formidable.
That's fine.
It's good to explore the symptoms from every angle.
That's what Analysis and Diagnosis is for.
You should choose the path you believe in.
Well, you'll do that without me telling you.
I'm not as wilful as you think.
You inviting me here with you
is a dream come true.
I'm great at karaoke.
I go to karaoke alone sometimes.
Singing love songs always reminds me of you.
Please don't get the wrong idea.
I only invited you to help me investigate.
- Investigate? - Investigate.
Besides, I don't like that.
Really? No love songs?
- Enka then? - That's not what I mean.
Wait a minute...
This is the room the girls used that night.
I wish I knew what to look for.
They ate all this?
Margherita pizza, takoyaki, seafood salad,
meat doria, carbonara...
Young girls have voracious appetites.
Miyabe-san, eat up.
What?!
It's vital to recreate the scene.
Tachibana-sensei says the same.
If I eat all this, can we sing a duet?
Eh?!
They're all negative.
No evidence of any drug use.
We were so sure it was drugs.
Maybe Satomi-sensei is right,
and it's an infection?
That's not possible.
We have to try another diagnosis.
Iwakura-sensei.
Aren't you getting in?
I am.
How were they?
The results of the girls' drug tests.
It's none of your business.
For the time being, I'm director here.
The results were negative. They didn't use drugs.
I see.
Then you need another diagnosis.
I know that.
But that's good, isn't it?
You've eliminated one possibility.
Ah, I know.
Our A&D department was discussed at the Medical Association social.
It has a good reputation.
I'm sure you feel smug about that.
It's just as you planned.
Please make sure things go smoothly this time.
You have no right to ask that.
We're not doing this for your sake.
I know that.
It's for the patients.
Well, Tachibana-sensei's there too, so I'm not worried.
Ah, of course,
you being the leader gives me peace of mind.
If you like, I'll drive you home.
No thank you.
I don't want anyone to see me with you.
Oh~?
Are you embarrassed?
Don't be ridiculous!
How long has it been since you've called me, Yukino?
What did you want to talk about?
Or is it a consultation?
About Tachibana-sensei?
How did you know?
You keep wondering about her.
I want to know the reason.
She's a famous neurosurgeon,
so why is she in A&D?
Why do you care so much?
Well, never mind.
Ah, Tachibana-sensei's old hospital...
Hakushukai West Tōkyō General Hospital.
I've got a kōhai who works there,
so I can try asking.
You're just going to leave like this?
- Hey, could we try again... - Sorry.
- You all seem on top form. - We're fine now.
- What are you looking at? - This.
Halloween these days is incredible.
It's in fashion right now.
We're just following the trend.
Still, that make-up and fake blood looks real.
We collapsed right after taking that pic.
It's gotta be that food at karaoke.
I thought that seafood salad was weird.
That must've been off.
But Tomomi-chan was fine.
Tomomi's suspicious. Why only her?
Did she do something to us?
Don't be silly.
She's been really worried about you all.
She's just faking it.
There's no way she'd worry about us.
Don't you all get on?
Of course, we're all good friends.
Rie, are you alright?
Yeah, how are they others?
They've been moved to the general ward.
Are you in the same room?
- No. - Okay.
Isn't that good?
Tomomi-chan, you must be glad they're all okay.
You were very worried.
That's right.
I've just been to see them.
They've recovered quickly.
It's good to be young.
So, Tomomi-chan,
how about you share a room with them?
It'll be more fun that way.
Oh?
What's wrong?
Don't you want to be in with them?
Listen, Sensei...
I don't need to be here, do I?
Can I be discharged this afternoon?
Ah~ Well...
It's true no symptoms have appeared...
No, you might still be unwell.
The game centre and karaoke were clear.
And the drug tests were negative.
So it wasn't infection or drug use.
It's still possible it was food poisoning,
but that doesn't explain Rie-chan's respiratory trouble.
If that had a different cause...
Allergy?
Not infection or drugs.
There's only one way hives could cover the body so quickly.
Anaphylactic shock.
That's why even though they ate the same food,
only one had different symptoms.
If we can find out what Rie-chan ate,
we might learn what caused the other symptoms.
- But how could we... - There's a way.
A way to track it down.
- A challenge test? - That's right.
To eat everything from Halloween night again.
Isn't that dangerous?
Deliberately causing anaphylactic shock.
But that's the only way.
It'll be worth it.
Let's get things ready.
I've been asked to make another TV appearance.
It's a special programme.
Really?
The prep school sensei who's been on lately
wants to MC a show with me.
That's great!
Those girls are making a racket again.
Children these days really are incorrigible.
The other patients are complaining.
Looks like it was normal food poisoning.
Iwakura-sensei, there's trouble.
What's wrong?
Tachibana-sensei is planning a challenge test.
A challenge test?
She thinks the girl with different symptoms has anaphylactic shock.
A challenge test is a last resort.
We can't let her go through with it.
- Contact Chief Secretary Sasaki. - Okay.
That reckless woman.
What's she thinking?!
Prepare everything they ate at karaoke.
I'll explain to the family and get their consent.
Hold it, all of you.
Murakami-sensei, Iwakura-sensei.
Just what is going on?
Everyone is finally recovering.
- There's no need for a test. - There is.
We haven't confirmed anything yet.
But what if something goes wrong?
There's certainly risk involved.
But since Rie-chan has shown an allergic reaction,
it's a good chance to ascertain the cause.
This isn't just to help Rie-chan.
We might learn why the others collapsed.
I don't care what you say.
I can't allow it.
We should use other tests, even if they take longer.
The blood tests they've had haven't shown anything.
- There's no other way. - Tachibana-sensei.
Are you ignoring my orders?
This is to save the patients.
Since it's come to this, we'll have to ask the director.
The director?
The director has ultimate responsibility.
Iwakura-sensei or Tachibana-sensei.
Let's ask the director to decide
which option we should choose.
Alright?
Wait.
If we ask Kitabatake, won't he agree to the test?
I've already considered that.
You have?
If we say he's put a patient in danger that way,
he'll be denounced by the Board.
Whichever he chooses, we win.
That's true.
A challenge test?
We've ruled out infection and drugs.
All that remains is anaphylactic shock.
That's still not certain.
Consider the physical impact on the patients.
Director Kitabatake.
They're already weakened.
Iwakura-sensei is the head of A&D.
Isn't that right, Tachibana-sensei?
Yes.
If you do this without her knowledge,
it will clearly be a problem.
So why is it, Tachibana-sensei,
you're ignoring her
and going ahead on your own?
Wait a minute...
- You said before... - I'll say it once more.
When Iwakura-sensei is here,
I can't allow you to do your own thing.
Understand?
By the way, Iwakura-sensei,
do you have plans for tonight?
Huh?
Thanks for waiting.
This is everything you ate at Halloween.
- At karaoke? - Yes.
We went and got them all especially.
Eat them one by one,
and we'll see if you have an allergic reaction.
Don't worry, we'll be here
so you'll be safe.
- What? - Hey...
Are you sure we should do this?
The director said we shouldn't.
- That's right. - Well then...
- That's why we will. - Huh?!
- I don't get it. - Don't worry about it.
Now, let's get started.
Rie-chan, which do you want to eat?
- Anything. - Okay.
How about trying the takoyaki?
There.
Well?
Does your throat itch?
It doesn't.
We should really wait 2 hours before the next test,
but considering the time between eating and the attack
we'll go with every 15 minutes.
Pizza.
Carbonara.
Grilled rice ball.
Vegetable sticks.
seafood salad,
meat doria,
waffle.
I'm full.
This is the last one, so hang in there.
Last is the mango pudding.
It had fruit pulp on top.
Is something wrong?
My mouth is tingling a bit.
I'll have a look inside.
Is it the mango?
It's mango oral allergy syndrome.
But that's not anaphylactic shock.
If it's not the food...
What could have caused it?
Do you know why people dress up for Halloween?
I don't.
It was originally an ancient Celtic festival
like Japan's Obon festival.
People said evil spirits and witches took advantage
and came along with the dead.
Like Obon.
So do you know what happened to the girls?
I wonder...
Not really.
You're worried, aren't you?
We thought food poisoning,
but the hives suggested infection
and drug use was also suspected.
But it wasn't either,
and the challenge test didn't show what caused the hives
only a slight allergy in the mouth area.
So you don't know the cause?
Everything we've considered has been eliminated.
Was it really an illness?
What?
Ah, that's my song.
Mango, huh...
Allergy?
There's only one way hives could cover the body so quickly.
Anaphylactic shock.
But there's also one girl with no symptoms.
There's no way she'd worry about us.
How about you share a room with them?
Mango...
Hives...
Human relationships...
What do you mean, "Not an illness"?
Symptoms, no symptoms, different symptoms.
The variation is too great for a single cause.
It's true there are lots of symptoms.
They were all together, so we've assumed
they should have the same illness.
So it was something else?
Mm.
But what...
It was you, right?
You did something at Halloween.
It's suspicious you being the only one with nothing.
Haven't you been waiting for a chance to get back at us?
- I've never even considered... - Don't lie!
What is it?
You and Rie are always cold to us.
Are you making fun of us?
We let you join our group, didn't we?
Yeah.
No one else would have you two.
We were only friends with you
so you'd show us your notes before tests.
What's going on?
Tomomi-chan!
Ganging up to bully her?
We weren't doing that.
We were just asking why she was the only one okay.
Yeah.
I heard this earlier,
but apparently Tomomi-chan is an excellent student.
She's only good at studying.
That doesn't mean she's popular.
Do Tomomi-chan and Rie-chan belong to any clubs?
They're in the science club.
Some kind of experiments and research?
They do a lot with that.
I see.
Science club...
It's just as you said, Tachibana-sensei.
I thought they were all friends, but they're not.
What we saw there
was just a small part of it.
I can see the full picture of this food poisoning business now.
I can't see any of it.
Tamaru-sensei, I have a favour to ask.
Ah, here it comes.
Okano Tomomi-san and Nagase Rie-san?
Yeah, they're both diligent students.
They do excellent work.
They even won a science contest.
Is this always kept locked?
Yes, when students use the drugs
they have to ask me first
and follow a procedure to borrow the key.
Even Tomomi-chan and Rie-chan?
Well, they're in the science club.
They have more freedom than other students.
- May I look? - Please do.
Please wear these, it's the rule.
Got it.
Tachibana-sensei, when you said
it might not be a disease
you meant it was poison?
The motive is bullying and human relationships.
And if members of the science club
have easy access to toxic substances,
it's clear who the culprit is.
Rie-chan, may I have a word?
Yes.
I hear you're in the science club at school.
Along with Tomomi-chan.
You know what this is, don't you?
Sodium azide.
I believe you're familiar with it?
Tamaru-sensei took this at your school.
Sodium azide
is used for inspecting water quality,
but it's highly toxic.
If it's dissolved in water and ingested,
it causes vomiting, convulsions,
low blood pressure and respiratory trouble.
All the symptoms Rena-chan and the others collapsed with.
I asked them about the fake blood,
and they told be you prepared it?
Blood paste capsules.
To make the blood around their mouths.
Rie, have you got the fake blood?
Natch. Just going to the toilet first.
You added sodium azide to the capsules.
You also decided how much to put in.
If they ingested too much, they'd die.
Ah, Rie, the blood?
Gotta have this.
Put the capsule in your mouth
and chew it to release the blood.
You gave them the drugged capsules,
but for yourself and Tomomi-chan
you'd kept some harmless capsules separate.
And when they developed sodium azide poisoning
it was mistaken for food poisoning.
What are you talking about?
Why would I do that?
Yes.
There is that.
The evidence is all circumstantial.
Up to this point.
Rie-chan...
Do you know why you collapsed along with the others?
You don't, do you?
It was outside your calculations.
The clue was the hives only you developed.
And yesterday's challenge test.
Hives and the challenge test...
What gave you an allergic reaction?
Mango.
But it didn't do much.
It was enough to show me.
People with a mango allergy
are known to commonly have another allergy.
Another allergy?
To this.
Latex.
So-called natural rubber.
There's a disease called latex-fruit syndrome.
People with an allergy
to mango, kiwi, banana, or avocado
are often also allergic to latex.
It causes anaphylactic shock,
hives and respiratory difficulty,
and can potentially be fatal.
The cause of your collapse
was anaphylactic shock.
The science club use disposable latex gloves
which you unknowingly produced antibodies to.
Then on Halloween night,
you wore them to inject sodium azide into the capsules.
Your condition deteriorated in the emergency room
because the doctors and nurses
wore latex gloves when they treated you.
In other words,
it's your latex allergy
that proves you handled the sodium azide.
Would you like to tell me?
Why did you do it?
I had no choice.
I didn't want to be bullied.
I thought if I joined a popular group
no one would bother me.
Did joining the group stop the bullying?
They used me to run errands,
and made fun of me.
But it was still better than before.
Tomomi is my only real friend.
That's why...
I can't forgive the others for bullying her.
Rie, Tomomi,
we're bored, so show us something fun.
How about running down the corridor in your underwear?
Ah, whoever loses the race
has to leave the grounds like that.
Yeah, sounds fun!
We can't do that.
Don't give me that crap.
Do it.
You wanted to protect Tomomi-chan.
So to stop Rie-chan and the others bullying,
you decided to punish them a little.
I didn't think it would be so serious.
I thought they'd just get stomach ache.
You did it so lightly.
Yes.
But even so,
one wrong step and they'd have died.
Even if you didn't intend that,
it can't be so easily forgiven.
I think...
...somewhere inside...
...I felt happy about getting revenge.
I could rebel against the people who'd started the bullying.
But that...
...is a form of bullying, isn't it?
It makes me the same as the others.
I'll go to the police.
I'll tell the police everything.
I think that will be best.
I believe your desire to protect Tomomi-chan
will be clear to them.
You can start over, I'm sure of it.
Do your best.
It wasn't ordinary food poisoning.
I never imagined for a moment
it was sodium azide poisoning.
Sodium azide has been specified as high risk
under the Poisonous and Deleterious Substances Control Law.
In the past it was used in contamination incidents.
If you hadn't noticed the latex allergy,
we wouldn't have solved this.
Hm? Wait a minute.
From oral allergy syndrome due to mango pudding,
you realised she had a latex allergy, right?
That's right.
Could it be...
you went ahead with the challenge test?
Ah, no, well...
What's going on here?
This is a problem!
Did you ignore Director Kitabatake's instructions
and disobey Iwakura-sensei?
If you disregarded my orders,
I will never forgive you.
But I don't know anything about this,
so there's no reason to get angry.
Iwakura-sensei?
I wonder how Rie-chan's doing.
She wasn't the only one to blame.
It was the bullying by Rena-chan and the others
that was ultimately at the root of this.
The bullies forget it quickly,
but the victims remember forever.
The scars on their hearts never disappear.
There's nothing good about bullying.
I hope they use this chance to make a fresh start.
Rie-chan, Rena-chan, and the others.
That's right.
It's been resolved?
That's good.
Thank you very much.
It's thanks to you.
You took Iwakura-sensei out of the way
to let me do the challenge test.
Not that it was easy to understand your hint.
If you do this without her knowledge...
- You said before... - I'll say it once more.
When Iwakura-sensei is here,
I can't allow you to do your own thing.
You meant if she wasn't here I could do as I liked, right?
What?
Not really.
That wasn't my intention.
What?
You should listen to your superiors.
You're a troublemaker.
Still, I enjoyed going for a drink with Iwakura-sensei again.
It's good to drink with a mature woman sometimes.
I asked about Tachibana-sensei.
Her surgery success rate is 100%.
She never fails.
She has a flawless reputation.
She started at Hakushukai West Tōkyō General Hospital 18 months ago,
and before that she worked at a hospital overseas.
Overseas?
It's common for top doctors like her.
But...
No one knows where the overseas hospital was.
Tachibana-sensei hasn't written it on her CV.
Is there a reason she didn't write it?
Or perhaps...
Is there a reason she's hiding it?
Mao.
- Welcome back. - I'm back.
Let's go.
- How was school today? - Lunch was delicious.
It was?
It looks like early onset dementia,
but something is off.
Help me! Help me!
Please let me diagnose Shizuka-san.
I refuse.
If we don't treat her now, her life will be in danger!
What you did was abduction.
The police have taken Tachibana-sensei!
I can't abandon someone who is suffering.
