You collapsed from a lack of sleep...
...and a deficiency of carbohydrates.
Then, the problem...
According the the results of the PET tests...
...your brain is consuming an extraordinary amount of energy.
Particularly, the section that governs insight...
What will happen to me?
I'm not sure...
...but it doesn't seem good.
Your brain...
...may undergo another change.
Are you all right?
I was told I should eat more bananas.
Huh?
He said my brain isn't getting enough sugars.
[The ultimate crime.]
[To take a form transparent as air and kill someone]
[...kill someone.]
[When I kill, and when I escape, no one will be able to see me.]
Would that really make you collapse?
Another main factor was lack of sleep.
It's true that running around on all these cases means I only get 8-9 hours of sleep a day...
You sleep that much?
[No one will be able to see me]
Is something the matter?
Please go ahead without me.
What?
[No one will be able to see me]
I'm sorry.
What happened?
Hyuga-sensei...
Hyuga-sensei!
Emergency
I'll go see what's going on.
Okay.
Ma-kun...
What do you think the emergency is?
Emergency
Part of the hospital will be off-limits for an on-site inspection.
Ma-kun, what's wrong?
Nothing...
It's nothing.
Go check the security cameras.
Yes, sir.
The victim is Hyuga Shinichi-san...
...he's a um...surgical professor here.
Yes.
He didn't come when we said we'd meet, so I came to get him.
He said he was going to the storeroom to check the inventory so...
Right, Araki-san?
Yes, sir.
We were supposed to meet regarding the upgrading of a type of medical equipment.
That's the inventory of the old model.
So...
...you...um...Chihara-sensei...
...Chihara-sensei, you heard the scream and came in the storeroom.
- Yes. - And then...
The rest of you came?
That's right.
But the murderer...
...wasn't here.
So?
I believe the murder weapon was pointed, like a screwdriver.
The murderer probably didn't get much blood on him.
It may be hard to get a lead on him.
And...
...there's only one way in or out, huh?
It's gotta be on the hallway's security cameras.
Look at this!
Tanbara-san! L-look at this!
- I'm looking already... - Look!
I'm looking already!
Ready?
This is the camera from the south side...
...and this is the camera from the north side.
First, Hyuga-sensei goes in.
Then you wait a little while...
This part!
This has to be an invisible man...right?
There's no such thing!
We have a suspicious person in custody.
We have secured a suspicious person in the restricted area.
You have the invisible man in custody?
- Look... - It's true!
Calm down.
Look, I'm telling you the truth!
What are you doing, Sensei?
Today, I came for some tests.
Oh!
That's right...are you feeling okay?
See? Did you hear that?
Did you hear that?
I am a patient. Just a patient.
Why would "just a patient"...
...be hiding here?
Tsukumo-san?
You're so loud...
I'm sorry.
I did it.
I'm the perpetrator.
T-Tsukumo-san... W-why?
- What's going on? - What?
Why did you do it? Huh?
Well..I thought that letting a dangerous guy like him stay loose...
...would be really bad, so...
...I had to do it.
- Him? - Well..
I noticed him when I passed by an older man...
- He was following the older man... - Hey.
Is that "older man," maybe...
...this man?
Oh! Yeah! How'd you know?
What? Then...
...Tsukumo-san, you saw the invisible man?
- Huh? - Who is it?
Who was it?
Who did you see?
It was...
...him.
Well... Um...excuse me...
See...I thought that if he was left to run around the hospital, he'd cause a lot of damage...
...so I searched frantically for him.
I ran all over...through the whole hospital...
...and finally...
...caught him here.
Then I realized...
...I was in a restricted area.
It's my fault the emergency call went out.
Well... No... That's not your fault, Tsukumo-san...
Go home.
Go home!
Never ever, not until doomsday, not before you die...
...not even if you do die...ever...show your face in front of me again!
Okay.
I don't want to see you again. Got it?
Oh, that's right.
Why are you two here today?
None of your business.
Did you say something about an invisible man earlier?
- It's got nothing to do with you... - That's right!
The invisible man has killed someone.
An invisible man has committed murder?
Hayashida!
Hmm...but...
...I'd really like to meet an invisible person. Wouldn't you?
I want to meet one too!

GIRIGIRI FANSUBS NOT FOR SALE OR RENT
In the hallway of the research wing where the incident occurred...
...there are a total of 5 security cameras set up.
Among them, 2 record the storeroom that became the murder scene.
This was recorded at 11:29...
...right when Prof. Hyuga entered the equipment storeroom.
And...
...the problem lies one minute later...
Even though no one is there to do it...
...suddenly, the door begins to open.
Five minutes later...
...Chihara-ishi goes to get him.
Here, Chihara-ishi says he heard Hyuga-ishi screaming.
Two security guards said they heard the same screams...
...and they arrived from 2 different directions.
They found the body.
If we leave the mystery of the door aside...
Doesn't it seem likely that this crime...
...was committed by the first one on the scene...by Chihara-ishi?
Between the time Chihara-ishi went in...
...and the time the guards arrived, there's only a time lag of 27 seconds.
I believe it would be impossible to commit the murder and hide the weapon in that amount of time.
There's only one way in or out...
...and there are no indications that anyone escaped through the window.
So what do you think the possibilities are?
The murderer...
...is invisible.
With regards to the murder weapon...
...forensics is evaluating objects seized during the search, however...
...they haven't found anything with any trace of Hyuga-ishi on it.
Sasa-san...
We'd like IPS to run an image analysis of the security camera footage...
...and determine the nature of the murder weapon.
Understood.
Funaki-san...
The 2 security cameras in question...
...and the other footage from within the building...I'd like you to enhance them...
...and find anyone who might be suspicious.
Nanba-san...
...you'll assist the forensics team in determining the likely murder weapon from the objects seized.
Natsume-san...I'd like you to determine the nature of the murder weapon.
Would it be okay if I borrowed Yuri?
What?
We'll probably need extra help...
...and it doesn't seem like neuroscience is going to be of any use.
Tsukumo-san!
Do you mind?
About the "invisible man" thing that Rinda-kun was talking about...
...do you think maybe the murder weapon is invisible too?
That's why no one can find it.
Right, every--
Hey, everyone!
An invisible man isn't impossible, right?
It's not impossible.
Wait... You mean...
If you're asking who might've had a grudge, I suppose it's me.
Hyuga-sensei...
...was really tight with the money...
Watch what you say.
Hyuga-sensei...
...was brilliant, both as a surgeon and as a scholar...
I can't think of anything he'd done to make anyone hate him...
Right, Wakui?
Right.
Well...
...had you heard anything from any of the patients?
Hyuga-sensei hadn't done any difficult operations here for 2 years, so...
Lately, they've all been done by me or Wakui here.
What?
That's really amazing...as y-young as you are...
I know this is rude...but how old are you?
I'm 28.
We're the same age...
Wakui is our Ichirou.
His thesis received a lot of attention in academic circles...
I just happened to pick a good theme for it.
A person could hate you, you know?
You're handsome and smart...
...and you even took Gotou-chan away...
"...you even took Gotou-chan..."
We're going to be married.
Really?
Yes.
Wow. Congratulations...
There's no need to clap...
Sorry...
It's possible that anyone in the lab could be harboring a grudge or feeling resentment...
Please be very careful of your personal safety.
If there's anything...don't hesitate to call.
Are you planning to tell them something?
Well...
...if anyone had a grudge against Hyuga-sensei...
...it could only be Chihara-sensei, right?
That may be, but...
...he wouldn't kill him, right?
But...Hyuga-sensei said it...
"Chihara-sensei..."
"...is taking bribes," he said...
There might be more to it.
What will you do if you tell them and you're wrong?
Megumi, you and I...
...would have to leave this place.
No one's leaving until we find it!
Then if you wrapped yourself in that fiber optic cable...an invisible person would be...
If you could divert all the light...
...and were able to synchronize the light waves...
...a camera wouldn't be able to see you.
Then, the murderer wore something that covered him in fiber optic cables?
I wouldn't wanna do it.
Tsukumo-sensei, your assistant's here.
Wouldn't you like to go back to your own lab soon?
The invisible weapon...
...have you found it?
You seem down.
All Natsume-san does is yell at me...
And everything's spinning because I used my brain too much.
Oh!
In that case...
...let's play shiritori. You start.
Why?
What do you mean, "in that case?"
Oh, I see. You're bad at it...
I'm really good at it.
I don't mean to brag, but...
...I've never lost.
Why would you lie like that?
Fine then.
Let's have a match.
Pencil [e-n-pi-tsu]
Okay, Funaki-san... "tsu."
- Huh? I'm playing too? - Yes.
Tsu... [tsu]
The "Tsu" from "Tsu city."
...communications equipment... [tsu-shi-n-ki]
...steam train... [ki-ka-n-shi-ya]
...arrow.. [ya]
...chestnut roasting machine... [ya-ki-gu-ri-se-i-zo-u-ki]
Does that even exist?
5....4...
- ...3... - Oh!
...balloon... [ki-kyu-u]
...cormorant... [u]
...lie detector... [u-so-ha-ke-n-ki]
Ki?
...memory... [ki-o-ku]
...district, like Shibuya district... [ku]
...air purifier... [ku-u-ki-se-i-jo-u-ki]
Ki...
...fox... [ki-tsu-ne]
...roots... [ne]
...like roots from a plant...
...rat-trap... [ne-zu-mi-to-ri-ki]
Ki?
- Why has it always been ki? - 5...4...
- ...3...2... - Oh!
...anal fistula... [ki-re-ji]
...character... [ji]
...like a letter of the alphabet...
...vending machine... [ji-do-u-ha-n-ba-i-ki]
...giraffe! [ki-ri-n]
Beep!
The estimated age of your brain...
...is about 54.
This might be far too much to ask of a brain aged so far beyond it's years...
...but do your best at work, okay?
Funaki-san.
What's he mean, 54?
I've used my brain so much it's exhausted. That's all!
Shiritori is...
...left side talking limit area.
What? Let me see...
Shiritori is...
...done in the left brain's language center.
It stimulates, in particular, the Wernicke area, the memory center...
...and the right prefrontal region.
It's a truly amazing game.
It's also effective at refreshing the mind.
Then your brain...
That's what he meant by "in that case..."
Huh?
How's it going?
Have you become invisible?
Can I see that last part again?
Yes, sir.
Oh! That-That man...
If he was there at this time...
...this person might've seen the invisible man, right?
Apply a low pass filter.
Yes, sir.
More. More.
Keep going.
How can I help you?
Just before Prof. Hyuga was killed...
...you passed very close to the murder scene, didn't you?
Why didn't you say anything?
At the time, I was deep in thought...
...so I can't really remember anything.
I'm sorry.
Did you see anyone suspicious?
No...
I'm sorry...
I really don't remember it very well...
There's something fishy about them.
Wakui, Chihara, and Araki...
I agree.
But all of them are visible.
None of them are invisible.
That's true...
"They're visible," what... Are you still here, Sensei?
Who's this?
Hello? This is Tanbara.
This is Gotou, the intern.
I have something I'd like to tell you...
I'll be there right away.
I'd rather not do this inside the hospital...
Would you be able to speak with me...
...at the end of the night shift tomorrow, outside?
Of course. I'll be there.
Then...please contact me tomorrow.
What's wrong?
Nothing.
Are you going to a meeting now?
Yeah.
With Araki-san and Chihara-sensei. The 3 of us are picking up from the other day.
I see.
Do you wanna meet later?
Where we always do...
Sure.
We can't ask Hyuga-sensei to be our go-between anymore...
...and it might be a good idea to postpone the wedding date a little...
Oh...yeah...
You're right.
Then...
....around 10?
Yeah.
Well then...good work today.
Thank you.
Chihara-sensei!
Hm?
I'll be there a little later.
Okay.
Excuse me. Excuse me.
Excuse me!
Excuse us...
Gotou-san!
Gotou-kun!
Hey!
Megumi!
Why did this happen...
The perpetrator disappeared again.
The invisible man?
You're the invisible man!
If she could just remember, we could catch the perpetrator.
How could you do something like that?
It scares me a little...
Don't lie to me!
It's not a lie!
I figured out who attacked Megumi-san.
I'll sue you for slander.
This is the victim, Gotou Megumi-san.
Megumi-san was going down the stairs from the 3rd floor to the 2nd floor...
As she got near the second floor...
Two guards heard her screams and when they arrived...
...other than Megumi-san, collapsed on the floor, they say no one was there.
Once again, the perpetrator had disappeared.
And...none of the security cameras on the stairway doors, from the 4th to the 1st floors...
...none of them caught the perpetrator.
Hey! Let's go.
Wait...Hey, wait!
Are there cameras on the stairs?
They had to cut costs, so there aren't...
And how is Gotou-san after being attacked?
Luckily, the wounds from the weapon were superficial...
...but in the fall on the stairs she took quite a blow to the head.
She's sustained damage to a large area of her brain.
Particularly...
...to the Wernicke area, and the area around it in the left brain that govern speech.
She won't be able to understand words, and won't be able to control them...
No matter what she feels or thinks, she won't be able to express it in words.
Then...even if she saw her assailant's face...
...she wouldn't remember any of it?
She may retain the memories, but...
...I believe that her becoming fully conscious of it, and giving testimony, would be impossible.
Isn't there anything that can be done?
If she could just remember...we could catch the perpetrator.
Isn't there anything we can do?
Even something experimental...
Um...
Can I do it?
Aren't you thirsty?
Shall we drink some water?
Here. This is water.
Please, have some.
It's cold, isn't it?
Then...let's use this towel to dry you off.
You don't like it?
Oh! Well I suppose not.
I haven't even introduced myself yet after all.
My name...
...is Tsukumo.
In kanji numerals you write it 9, 10, 9...
...Tsukumo.
Tsukumo-san...
Tsukumo-san? Um...
Is that really a medical treatment?
The human brain...
...is built much more strongly than everyone thinks.
Even if it gets hurt again and again, it keeps working...
...it rebuilds...
...and to that end, someone must give it a hand.
Talk about all sorts of things...
...allow it to experience all kinds of things...
Getting outside stimulation helps the brain learn to function again.
Will that really heal her?
At the very least...
...I've seen one person cured by it.
My name...
...is Wakui Masakazu.
Wa...
Oh!
Games are good too.
...like shiritori...
Shiritori?
Shiritori activates the brain.
Shiritori?
I'll try it.
These are...
...pajamas... [pa-ja-ma]
...pajamas.
Pillow.
...pillow... [ma-ku-ra]
The guards came from both above and below...
...and found Megumi-san here, right?
Huh? Yeah...
But...at the time...there wasn't anyone here.
Tanbara-san...
What if someone hid there, a few hours in advance...
...and attacked Megumi-san? Would that be impossible?
We looked at the footage from every camera...
Everyone who entered the stairwell before the crime left before the crime.
Which means...
...that at the time of the crime...
...there was no one on the stairs.
Then...it really was the invisible man, huh?
You really think that's possible?
Megumi. You used to like this, right?
Egg.
...egg... [ta-ma-go]
And this...
...this starts with "go..."
"go -"...
...ma.
That's amazing, Megumi!
...sesame... [go-ma]
You're really amazing, Wakui-san!
You do all your work like you usually do...
...and you've helped Megumi-san come this far...
Actually...I'm falling apart at the seams...
But...
I have hope, so...
Hope?
Yes.
Hope...you say...
What are you doing?
Nothing...
Tsukumo-san ran all over the hospital...
It's hilarious!
We took the footage, in chronological order, and edited it together.
Run that back...
Araki-san gave it to Chihara-sensei?
I'm saying that he may have accepted bribes from him.
It's just a rumor, you understand!
Do you think you could tell me the details?
Chihara and Araki...are partners?
That's right. It's not implausible, right?
That's the inventory of the old model.
I believe the weapon was pointed, like a screwdriver.
It's really very close...
...but it's definitely not it.
What?
The pointed tip is the same...
...but this would cause the edges of the wound to be ragged.
The weapon is probably a little thinner...
...and smooth.
But...
...there...there weren't any thinner ones...
There's this new model that's set to be launched in July of 2009, but...
You can't use something...
...that isn't being sold yet, right?
We were supposed to meet regarding the upgrading of a type of medical equipment.
No...
- You can. - Huh?
That day, Araki...
...he came to meet about the new model.
I'll go take Araki...into custody!
Why are you taking a call now?
Hello. This is Hayashida.
Tanbara-san!
They said that Megumi-san may have remembered who the perpetrator is.
Megumi...
The person...
...who was it...that did all those scary things to you, Megumi?
L-o-n-g...
...h-a-i-r...
Someone with long hair, right?
...g-r-e-y-r-u-l-e-r...
A grey ruler...
...w-h-i-t-e-c-l-o-t-h-e-s...
White...
...clothes...
...b-l-a-c-k-g-l-a-s-s-e-s...
The person wore glasses?
Is there anything else?
...c-o-u-l-d-n-o-t-b-e-c-o-m-e...
What was it the person couldn't become?
Will you try to tell us?
Megumi...
Megumi?
Long hair...white clothes...black glasses...
...and a grey...
...ruler.
It might be Chihara-sensei...
What does she mean "couldn't become?"
Chihara-sensei...
This Spring, Hyuga-sensei...
...was supposed to have made him an associate professor.
Why didn't you tell us that?
You knew, didn't you?
I don't like telling people things...
...if all I have is supposition.
Where is Chihara-sensei now?
Wait a minute, please...
Chihara-sensei isn't invisible, is he?
-Tsukumo-sensei. - Yes?
The invisible man...
...is you!
First...Tsukumo-san...
...went down the north stairs from the 3rd floor hallway...
We thought he'd appear on the second floor...
...but he reappeared on the first floor, in the hallway by the south stairs.
What about it?
In order to appear at the south staircase on the 1st floor...
...Tsukumo-sensei would have had to pass from the north stair...
...to the south stair through the 2nd floor hallway...
...and taken the stairs down from there.
In short...
...he should have passed through the 2nd floor hallway...
...but we have no footage of him doing it...none at all.
What did you do?
What did I...well...
Oh...I was probably like this...
...pressed up against the walls.
I knew it.
What? Is that all?
Oh, that's what happened.
I don't get it. Explain it so I can understand.
No, it's really very simple. Cameras have blind spots.
If you stand behind the camera like this, you won't be caught on video.
The murderer probably...
...passed through the cameras' blind spots to get from the stairwell to the storeroom...
...walked, pressed up against the walls, all the way up to the equipment storeroom...
But you can't open the door from there, can you?
All you have to do is walk, right?
But the cameras would see you if you did that! You're right in the middle of the hallway!
No...
If this narrow area isn't seen by that camera...
...or by this camera, then...
If you did this...
...and opened the door...
...you could get inside.
This door is quite wide...
...so even if the cameras didn't catch the middle...
...it's likely that no one would feel there was anything wrong.
But...
...they're security cameras, you know.
You try to set them up so they don't have blind spots!
What if someone changed the angles of the cameras?
If the murderer was Chihara-sensei...
...then Chihara-sensei...
...passed through the cameras' blind spots...
...sneaked into the equipment storeroom...
...and killed Hyuga-sensei.
Then he went back the way he came...
...popped into the lab on the 3rd floor...
...he pretended that he was going to go get Hyuga-sensei...
...and went to the storeroom, making sure that he'd be seen on the security cameras.
Then, pretending to be Hyuga-sensei...he screamed...
The guards heard that scream, and came running over here.
The security cameras don't pick up sound, you see.
He made very good use of that fact.
But...
...this still doesn't prove anything.
If we're lucky...there may be fingerprints left from when he moved the cameras...maybe...
Tanbara-san!
...in Araki's attache of samples of the new model...
...we found positive reactions for both Hyuga-sensei and Gotou-san's blood.
And they're a perfect match to the wounds.
They're 100% consistent with the projected shape of the murder weapon.
There they are.
All right...
Oh!
These were on your computer.
You were ruthless and thorough in laying your plans, weren't you?
I worked for that old man for over 10 years.
And now...
..."you'd be better in private practice," he said.
What about Araki?
Was he an accomplice?
I just used him.
And when it seemed your crime might be exposed, you attacked Gotou Megumi-san, didn't you?
No.
That wasn't me.
She remembers you attacking her. Don't lie to me!
It's not a lie!
I've been thinking it was strange this whole time.
...wondering, "why Gotou?"
What are you listening to?
What?
Well...
...it's a tape of Megumi-san's testimony.
Wasn't this case solved?
I feel like there's a blind spot...that no one's noticed yet.
What's this?
I knew it.
Funaki-san...
Excuse me, I'm sorry...
...can I use this a sec?
Um...
What's going on?
I found you.
But there's nothing on the videos...
I saw him.
...the perpetrator.
Megumi-san...
Who was it...
...that did all those scary things to you?
...long...
...hair...
Someone with long hair, right?
...grey...
...ruler...
A grey ruler?
...white...
...clothes...
White clothes...
...black...
...glasses...
The person wore black glasses?
Is there anything else?
...could not become...
What? What couldn't he become?
Will you try to tell us?
Megumi-san!
Please look into the scope.
That's enough, thank you.
Ah, you don't have to. It's all right.
Did that help you figure something out?
Yes.
I figured out who attacked Megumi-san.
What?
Wakui-san.
It was you, wasn't it?
Wakui-san...
...is Megumi-san's fiancee, you know!
He would never...
No, no...listen to this tape one more time, listen closely.
Who was it that did all those scary things to you, Megumi?
...l-o-n-g-h-a-i-r...
Someone with long hair, right?
...g-r-e-y...
Shiritori?
That's right.
The questions and answers are a game of shiritori.
Um...what are you talking about?
What?
Megumi-san didn't remember who attacked her.
She's just playing shiritori, repeating back answers...
...exactly as you taught them to her.
Shiritori?
I didn't notice...
...but it's certainly true.
This area here is the area that governs long-term memory.
If Megumi-san were truly remembering who had attacked her...
...then when I'd asked her the questions...
...this, the parahippocampal gyrus, and the area behind it should've shown vigorous activity.
But they didn't react at all...
Her words and her memories were not linked...
In contrast...
...the part that was working the hardest was this, the prefrontal area...
Memories are temporarily stored in this area...
...and in order to compensate for the damage to Megumi-san's brain...
...it's just beginning to use this area...
In short...
...the words that Megumi-san spoke...
...are recent memories. This is the proof of that.
What I'm about to say is my own conjecture.
...but it's the only scenario that explains everything.
First, you, quite by chance...
...witnessed Chihara-sensei entering the storeroom to kill Hyuga-sensei, didn't you?
And when you saw his strange behavior...
...you realized the trick to avoiding the security cameras...probably...
Then when you heard that Hyuga-sensei had been murdered, it hit you...
"Chihara-sensei must be the murderer."
But you decided not to tell anyone.
You said...
...you don't like telling people things when all you have is supposition, am I right?
On the other hand, Megumi-san...
...couldn't keep quiet.
She was going to tell the police that Chihara-sensei had a motive...
What will you do if you tell them and you're wrong?
You tried to stop Megumi-san, but you weren't able to do it.
Could we speak outside?
That's when...
...you used the trick Chihara-sensei used...
...and tried to kill Megumi-san.
You probably guessed what the murder weapon had been too, right?
You made up an excuse to get Araki-san to lend you a sample...
...and you lured Megumi-san into traveling down the stairs from the 2nd floor...
Sure.
You waited for the policemen to pass by...
...and, just like Chihara-sensei did, you passed through the cameras' blind spots...
...and headed for the stairs Megumi-san would travel down.
That's where you attacked Megumi-san.
When they heard her screams, everyone came running...
...so you hid there...behind the fire doors...
...you pretended that you'd heard the screams and come running...
...you joined everyone, as if you'd just arrived.
Megumi-san...
...didn't lose her life...
...but, conveniently...
...she'd lost her memory.
You used her condition...
...to make her give false testimony, as insurance.
That's a very interesting story, but...
...it lacks coherence.
Why on earth...
...would I want to kill Megumi in the first place?
I don't have a motive...
That's exactly right.
How could you do something so terribly cruel to your fiancee?
Won't you tell me the reason?
I'll sue you for slander.
Wakui Masakazu...
...you took bribes from Araki, didn't you?
Megumi-san thought it was Chihara-ishi that took the bribes...
...but when the police investigated, your name was the one that popped up.
The reason being...
...Chihara didn't take the bribes...
...you did!
It's a scandal that you, with your bright future, would want to avoid.
Even if that's so...
...it doesn't prove that I attacked Megumi, does it?
What did you say?
Data from an fMRI...
...doesn't constitute evidence either...
Trying to use things like that...
...to say I tried to kill my fiancee is just...
He's right.
I have video that will count as evidence.
It was caught on the security cameras.
Watch carefully.
This is...
...what everyone looked like, right after Megumi-san's scream, as they ran to her.
The security cameras in the hallways, all of them, from the 1st floor to the 4th...
...and not a single one caught you on tape.
That's proof.
You heard Megumi-san scream and ran to the stairs.
If that were true...
...then you should be on one of these cameras.
...but you aren't.
Why is that?
There's only one answer.
You...
...were hiding in a blind spot.
In trying to play an invisible criminal...
...you made yourself too invisible.
When did you start...
...to suspect me?
From when I heard you use the word "hope."
I thought that "hope"...
...might have been that Megumi-san would regain her memories...
...but it could be...
...that you were hoping she stayed like this, unable to remember.
Which one was it, really?
Probably...
...I was hoping for both of them.
How could you do something like that?
I don't know how amazing your work is...
...but it's just research.
Why...
Why would you do this to someone for that...
Research takes money...
That's why, no matter how unscrupulous the methods...
...I made the money.
I did that for years and years...
...and, finally, got here.
This is where it was all supposed to start...
That's why...
...I couldn't let this be destroyed...
What is that?
This is the state of Megumi-san's brain as she was shown a picture of you.
Can you see that the amygdala is active?
This...
...is where you see a tremendous reaction in the brain, when a person is shown someone they love.
...before you can think about it, unconsciously, this area will react.
Take it.
It's said that it might be the true form...
...of that emotion we call "love."
I'm sure...
...that your brain would appear the same way, wouldn't it?
After all...
...you hesitated, didn't you?
...and so...
...you couldn't kill her...
Ma...
...what's wrong?
Ma-kun, what's wrong?
Nothing...
...it's nothing.
Neuroscience really is amazing, isn't it?
To be able to tell that much...
But...it scares me a little...
Me too.
Amnesia...
Can a person with amnesia kill someone?
[A pianist with no memory]
What is all this?
Do you think it has some kind of meaning?
[A code hidden in music notes!?]
Someone's framed him...
I did it...
Do you know what I've had to go through to get here?
You did it?
He forgets in about an hour...
It's not easy to kill someone.
Really, get a clue, would you?
You should forget about it...
Are you okay... Ah!
Masaru-san?
For a girl like you to have been so close by...
I knew it...
It's not natural, is it...
The murderer...
...is someone else.
