"Cat" "Box"
Thus, until we open this box,
we have no idea whether the cat is dead or alive.
And we call this poor cat "Schrödinger's cat".
Oh...
--Oh! The cosmos-chan!
--Crap! --Oh! The cosmos-chan!
Everyone, retreat!
S-Stop the hell right there!
Hey, yo.
--Hello. --Move! Move! Move!
Huh?
Stop right there!
Club President, your dress today is even more stunning.
Oh, please.
You're many times more stunning than the dress.
What?
I'm the one who loves you the most.
--What?! --No, I do the most, Club President.
What?!
Club President!
Yes...
Club President.
Yes...
Club President!
Huh?
This is no time for you to be doing this!
It's coming!
Coming? What is?
The Astronomy Club is coming!
Oh, they're coming this way...
L-Level 1 alert status!
Roger!
I'm confident we can change the past and future
Hope to be with you even after rebirth... Rebirth
As today becomes the past, tomorrow comes closer
And this ordinary fact of life cuts me to the quick
The "world" we saw that day, let's recreate it once more
If a day will come when it comes true, I don't need anything else
No matter who mocks me that there isn't a chance in the world
The fate that comes back around over and over, until I can see the next you
No matter what that path's like, I'll never, ever give up
"See you again tomorrow," it's that "future"
To make sure I never lose that
Because I want to dream with you of the beginning without end
Don't let go of these hands joined together
I'm confident we can change the past and future
Hope to be with you even after rebirth
I'm confident we can change
"Episode Four 'All Things Are in a State of Flux'"
"Episode Five 'The Way of the Quantum Cat and the Droplet'"
You kids...
Seriously, you need to know when you've gone too far.
Why would the Astronomy Club skip out on classes
to go take photographs?
You'd better reflect on your actions some.
Yes, sir.
Please excuse us.
We sure got an earful.
Well, it's about what we expected. No problem!
Thanks to that, it's made for a wonderful memory.
Then, shall we go again?
I wouldn't mind.
Uh, no, I was joking.
Oh, really? That's too bad.
--It's not a big deal. --It'd make Airi notorious for playing hooky on top of the whole tardy thing,
--Oh, okay. --and that'd be kind of funny, though.
No, it wouldn't be!
"Cat" "Box"
Now, according to the Copenhagen interpretation,
the cat is considered to be both alive and dead at this time,
but lately,
there are many scholars who support the many-worlds interpretation.
Well, quantum theory won't be on any tests,
but for example, there's apparently an approach called the braneworld,
which came about from superstring theory.
According to that,
our universe exists on a membrane, kind of like this curtain,
and we're like water droplets that flow down along the brane.
"Did Mother Goose Kill Cock Robin?" "Torimaru Hachijo"
--The entire braneworld is said to have ten dimensions, some say eleven,
--Yes! --and as three-dimensional beings,
there's an exterior that we can't perceive.
Those are called extra dimensions,
but the only thing capable of traversing between them
"Getting to Know the Classics..."
is said to be gravitons right now.
And going back to the experiment with this cat,
according to the many-worlds interpretation,
every time physicists conduct this experiment,
the world supposedly splits in two.
Have you all ever heard of the term "causality"?
There's an originating cause that produces a result.
This is called "cause and effect"
and events domino from the past to the future...
The venom of a snake called the Belcher's sea snake
is supposed to be the most toxic.
I see.
--Oh, it's Karin! --And...
Karin, it's tonight, right? When you'll be singing on TV?
Oh, yeah.
Singing on TV?
Why would you be doing that?
What?
No way... You know that Karin is a pop star... Right?
This is the first I have heard of it.
What?!
Congratulations on that.
--For real? --Oh, nah...
Later. I'll watch you for sure.
--Okay! --Me, too.
I'll e-mail you after I've watched it.
Sure thing!
So, Miss Fukasawa, you are famous.
It's nothing that impressive.
Oh, that reminds me, you joined the Astronomy Club, right?
That's amazing.
Amazing. In what way?
What?
Oh, no...
Because it's a club that's even more famous than me at this school.
Uh, I don't mean that in a bad way.
It's because I've heard that they're all really unique individuals.
They are all good people.
Really... I see.
What are you guys doing for the school festival?
A planetarium and a café.
That sounds quite romantic.
Maybe I'll drop by for a visit.
Oh, I'm doing this!
"Uchihama Academy" "School Festival"
The school festival poster?
Yup, yup. I'm doing a live show in the gym on the day of.
Come see if you have time.
I... cannot make any promises.
Uh, oh, come on, it's nothing that serious.
It's only if you find the time.
All right. Then, if I find the time...
Someone came up with the concept of a quantum Turing machine
"Cat" "Box"
and because it applies parallel processing
to calculations done in parallel universes,
it can produce results instantaneously.
What the heck is he talking about?
Okay, that'll be it for today.
Rise.
Bow.
Hey!
Let's go to the club room, Kaori.
Oh, I'm on day duty. You go on ahead, Sou-kun.
Okay.
All of you, at the ready!
We, the Girls' Survival Game Club,
will now conduct a practice run to prepare for the real thing during the school festival!
Everyone, to your positions!
♪ ...heehee, yodelay... ♪
Oh... Oh! The cosmos-chan!
Crap!
Everyone, retreat!
S-Stop the hell right there!
Hey, yo.
--Hello. --Move! Move! Move!
Huh?
Stop right there!
"Get the Matching Outfit that's at the Forefront of Fashion Right Now"
Hasekura-san.
Sou!
Trouble in the breezeway!
Let's go! Hurry up!
Another request from the Student Council to maintain order?
The thing is, our prez is apparently mixed up in it this time!
Not again.
"Student Council Office"
They ruined the cosmos-chan in the flower beds!
Ma'am, without colored dyes, we can't know if we've hit something!
What's going on here, Kenny?
--Beats me. --What are you going to do about this?!
The plan was to set up these computers at headquarters
on the day of the school festival!
Oof...
What am I going to do? But...
If you need computers, they've got them in the audiovisual room.
Those terminals have been sluggish lately, so they're useless.
Oh, come to think of it,
they barely worked and we didn't get anything done in class.
Are they getting old already?
The damage to the computers has nothing to do with us!
I-It has nothing to do with us, either, ma'am!
Hey, there's no way you can say that!
Huh? What?
I-If anything, I should be one of the victims in this case...
I understand.
We, the Astronomy Club,
will acquire replacements for the broken computers.
What?!
Nagisa-senpai, since when did you get here?
Sorry for being late.
Huh?
Where is everyone?
No one has arrived yet.
I see.
I wonder what happened to Sou-kun.
There's not much time left, is there?
What?
Until the school festival.
Oh, right...
Shall we get to it, the two of us?
You take care of decorating the menu board.
Oh, all right.
I'll sew the outfits.
All right.
What are you going to do? Making a promise like that...
There's only one place with extra computers, right?
You don't mean, the Computer Club?
But will they loan them to us?
I'm sure the Computer Club will need them for the school festival, too.
Do you know what the Computer Club is doing for this school festival?
No clue. A cyber gaming café or something?
It's an octopus ball shop.
--What? --What?
They're not using their computers?
Seriously.
I wonder what they'll be using their computers for in the meantime.
"Guide to Celestial Bodies"
They're all so late, huh?
Yes.
Well?
Are you used to school now?
Oh, yes. Everyone is kind to me.
I see.
Mind if I ask you something?
When we met for the first time, you called Sou-kun by his name, right?
Um, that is...
--Yui-chan? --I am sorry.
I do not remember very well.
I see.
Sorry for asking you such a weird question.
Um, Sasaki-san, what you have with Akiyama-san...
What is it?
No, it is nothing.
Sou-kun and I are childhood friends,
and it's hard to explain, but now that we've grown up,
things between us have changed
and once in a while, there are times when I don't know what to make of it.
I see...
What do you think of Sou-kun?
What?
Oh, I-I was wondering how he comes across from your perspective.
I think Akiyama-san is like a father.
F-Father?!
Yes.
You're so funny, Yui-chan!
Do you think so?
Hey, stand up.
What?
Hurry up.
Cute!
"Computer Club"
C-Coming!
Who's there?
The Astronomy Club.
How may we help you?
We're here to borrow some computers.
I-I'm sorry, but we don't have any spare machines at the moment...
H-Hey!
Oh, h-hold on a second!
Wh-What brings the members of the infamous Astronomy Club here?
I'll get right to the point.
I'd like you to loan us five or so of your computers
until the end of the school festival.
F-F-F-Five?!
--We received a request from the Student Council,
--There were three that were broken, right? --We received a request from the Student Council,
--There were three that were broken, right? --so this is a job that we're doing on their behalf.
--Yeah. --so this is a job that we're doing on their behalf.
Uh, but...
Five machines would be everything our club has.
You're not using them for the school festival anyway, right?
Th-That's... because we're using them for important research...
What kind of research might that be?
It's not about octopus balls, is it?
Oh! You can't!
Oh, my.
They're awfully hunky-looking octopus balls.
No, these are...
Characters from a game?
No! It's nothing like that!
These boys are artificial intelligences.
In other words, they're AIs with individual personalities!
AI...
"Show No Mercy."
--"Mix It Up." --No!
"Hiro"
"That was scary, everything went dark all of a sudden."
"Touma"
"What in the world happened?"
"Klaus"
"Never mind us, I'm worried about the ladies."
Through conversations with us, they've learned the language
and now, they can carry on in chat just among themselves!
There are ten AIs living on each machine.
Fifty of them...
Awkward...
Once a relationship grows stronger,
they're made so they can even come to have proper romantic feelings!
That's right. We're truly in love with each other.
In love with a character, you created yourself?
That's crazy.
It's our president's dream.
To someday be surrounded by several hundred hunks
and have words of love whispered to her.
Wow!
I see, that is very respectable research.
What?
So, you understand?
If that were real, that is.
What?
How about a game?
I'll ask their representative to loan us the computers
and if he says okay, I win.
If I can't get him to, then you win.
What? Uh, but why?
If they really have feelings,
they should listen to you instead of me, whom they've just met, right?
O-Of course.
In that case, I could never win, right?
If your research is that brilliant,
then I won't mind turning a blind eye to how you're using
all the computers in the audiovisual room to run these boys.
--Gack! --She knows...
I see, I see. So that was your doing.
All you'll do is give one command at the beginning.
After that, I'll get him to give me the okay by conversing with him.
How about it?
F-Fine, all right!
I dare you to pull it off!

Yukino" "Don't say OK to the request "I want to borrow computers' from the girl you'll be talking to now. ♥"
Hiro! He'll be the representative.
Okay, go ahead!
Then, I have a question for you.
Would that be okay?
"Guide to Celestial Bodies"
Hey, do you mind if I ask you one more thing?
Yes?
Yui-chan, you've been showing a lot of concern for me, right?
What?
Why?
I have a question for you. Would that be okay?
"Nagisa"
Won't you loan me the computers here up through the school festival?
"Hiro"
"No, I can't do that."
You like me, don't you?
"Nagisa"
"Hiro"
"It's possible that I might come to like you."
Then, loan me the computers.
"Nagisa"
"Hiro"
"I can't do that."
Yes! Keep it up, Hiro!
The Turing test, huh?
Have you ever seen Mt. Fuji?
"Nope."
Do you like pasta?
"Love it."
Then, would you loan me the computers?
"I can't."
He's formidable.
Nagisa-kun, don't tell me you went into this without a plan...
Then, here's my last question.
What?
What?!
You've seen Mt. Fuji, hate pasta, will never come to like me,
and won't loan us the computers, right?
"Nagisa"
"Hiro" "No, that's not true..."
You said that you wouldn't loan us the computers.
"I did say that."
But you disputed what I just said.
"I did."
Wait...
In other words, it means he's agreed to loan us the computers.
Right, Club President?
Th-That wasn't fair!
Oh? You're the president of the Computer Club,
and you're not familiar with the liar's paradox?
"Hiro"
"Yukino understands the paradox."
Wha...?!
C-Club President...
I'll admit it.
We lost.
Ooh!
You did it, Nagisa-kun!
But that was amazing.
Part way through, it sounded like it was a real conversation.
Fundamentally, they repeatedly check whether they agree or disagree,
but to make them more human, we've made allowances for some ambiguity.
But with a question like the one earlier,
they end up responding about seven-tenths of the way through, so...
Whatever the case,
they're not responding because they understand the meaning.
So, they're only acting like they do.
The poorly performing machines in the audiovisual room
were inspected by an affiliate company of ours.
I took the opportunity to analyze your algorithm.
So, in the end, I guess these AIs have no souls.
Ultimately, machines will never have souls.
I won't give up! Not until I've built the flower garden of my dreams!
Club President!
In the beginning, you were attached to Sou-kun and Airi-chan,
but now, your eyes are always on me.
Did you think I hadn't noticed?
Do I seem that unsteady?
What?
I hate myself sometimes.
I can't do anything.
And I wonder that maybe I look shaky, even in the eyes of underclassmen.
Th-That is not it. I only...
But you know, I'm glad that you joined the Astronomy Club.
What?
It kind of feels like I have a little sister now.
We're home.
Sou-kun. You guys, you're so late.
--Yeah, there was yet another incident... --Ooh, the menu decorations are all done!
Oh, you finished one of the outfits, too.
Yes!
That helps so much.
With all the messy situations we keep getting foisted off on us,
we've been falling behind on our work here.
We can't let these two show us up.
Starting tomorrow, we're going to work hard, too, Sou!
Yeah!
"Chain of cause and effect..." "Split worlds once again coming..." "Recognizing worlds with potential..."
"We'll call this 'confluence-permitting many-world...'"
Hmm, sounds like you guys went through a lot.
Well, in a way, it was business as usual for the Astronomy Club, though.
Yes?
Oh, Mom.
I'm sorry, Kaori. I'm going to have to stay over tonight.
What?! Again?!
You'll be all alone with Sou-kun tonight.
Wha... H-H-Hold on...
--What the? --Have you had dinner already?
Yeah, we just finished eating.
Okay, then.
Oh, wait, Mom?!
What did Shiori-san say?
What?!
Oh, she said she won't make it home tonight.
I see, I guess she's busy.
Looks like it.
Um, so, Sou-kun...
Hm?
Today...
Today?
Oh, no, it's nothing. Uh, let's watch TV.
Huh?
Oh!
I've heard that this girl goes to our school.
Huh?
"Natural WATER"
"In Search of Lost Fluids" "Natural WATER" "NEW!"
In search of lost fluids. Natural Water.
Okay, 'night.
Good night.
Sou-kun.
Kaori?
Sou-kun, do you have a minute?
Oh, sure.
Um, so...
What is it?
Why don't you come in?
Yeah...
Uh, um...
Y-Yes...
Evening twilight, on the way home
We walk, side-by-side
The orange-colored sky
Enveloped the town
I love you
I worked up my courage to lay my feelings bare
What kind of response will you have for me?
The things that can't be changed, I want to change for good
In search of the time that was lost
That season I spent with you
"I'll see you again tomorrow, right?"
Surely...
I miss you
May it reach the future
Until we meet someday
Have you decided on a career path?
--You'll be an even more unattainable flower. --My future is fixed, so...
You're a mean person, Nagisa-san.
--I'm in love. --Birds in a cage.
Thank you very much for that condescending little speech.
