Here's the will.
I've hidden the notebook at the appropriate place.
It will activate and assail the enemy when the time comes.
Understood.
Have you perfected the spirit-conjuring spell?
I've rehearsed it repeatedly.
By the way...
Do I really have to leave?
It...
breaks my heart!
Even though you say my life is in danger,
I can't lie to all my students and rush off into hiding.
What's more, it's almost July-
That's exactly why.
Principal, your highest priority is to find Nostradamus' Key and secure it.
Our adversary is most likely an evil entity attempting to open the gate to hell.
However, we have yet to uncover its identity.
If last night's attack was only the beginning...
There is no other way.
Ri-Right now?
I am just as reluctant as you are.
I-I'm not prepared...!
At least tell me where I'm going...
That's for the spell to decide.
Fulfill your duty.
Prithee!
To a distant place!
Longus quoquam!
Where...
Where am I?!
July 19
Papa is?!
Yeah, he's alive.
I don't know where he is,
but the Vice Principal used magic to ease his escape.
Papa's...
alive.
Then...
Right now, Papa must also be searching for Nostradamus' Key.
And he'll be back here by August...
with a really confused look on his face.
I'll get to see him.
What are you going to do, Bunmei?
Will you go back?
Y-Yeah.
The mission's already over,
and the peaceful future is awaiting the return of its glorious hero.
What's wrong?
Nothing.
I'm just relieved that a wussy teacher is going away.
I should transfer, no... I think I should just resign.
I'll give a speech at the closing ceremony.
See you.
Hello?
Oh, my! You're Uchida Fumiaki-kun's mother?
Please forgive me!
I've been so busy since we last spoke that I couldn't get in touch!
Not at all!
About the performance,
it's still scheduled for the day after tomorrow, the 21st, during the closing ceremony, right?
Spoon-bending?
Oh, of course!
I would like to meet you so that we can discuss the details...
Yes.
I'll see you at 3 PM, then.
I'm looking forward to it.
Y-You invited my mother? To the closing ceremony?
And the great spoon-bending Bunmei-kun.
You wanted to see them, right?
Sorry for not telling you.
I wanted this to be a surprise.
Wait a minute.
I don't remember anything like that.
I'm sure that if I came to a place like this as a kid, I would remember it...
I wouldn't be surprised at all!
But, I had never been to this academy.
Not even to Matsushiro!
Maya, you saw them too didn't you? My memories!
These are all I can remember so far...
Now that you mention it...
Visions from that time blacked out all of a sudden...
Bunmei!
W-What's wrong?!
S-Stop it...
Stop it!
My...
Don't destroy it!
You're being discourteous.
That school seems pretty amazing...
Say, could you take me there tomorrow?
Not happening.
You've got summer homework to do.
But-
Don't you make me repeat myself!
Sorry for the wait.
Oh my- Bunmei-kun!
Are you Uchida Fumiaki-kun's mother, by any chance?
Yes...
I always follow you on TV!
Um... do you have chopsticks?
Chopsticks?
Who eats curry with chopsticks?
In other words...
we destroyed the world by ourselves?
Don't fuck with me!
I didn't say that.
Then what?!
That's what I'm trying to figure out right now!
History repeats itself, huh?
Quite the possibility.
This is Number Six.
I want to ask you something.
Please respond.
What is it, Number Six?
It's about the closing ceremony in two days.
The day of the prophecy.
Maya invited Uchida Fumiaki here for a performance.
To put it simply, I'm going to see my younger self.
But... I don't remember doing something like this at all.
What's happening?
That's it!
Listen carefully, Number Six!
Do not, under any circumstances, meet the past you!
Don't meet him?
Why?
In Information Science, there is something called the Ramachandran-Fischer conjecture.
It states that there is only a limited amount of information that can be processed in a given space.
When this limit is exceeded, a dimensional distortion occurs.
What are you talking about?
In plain words please.
Think of you, your future self, as a single information set.
It's a massive feedback of information from the future that affects space-time.
Processing this information induces thermodynamic problems.
If you meet someone else, they're absorbed with reasonable fluctuations.
But if you meet yourself, the fluctuations deviate greatly,
and create a dimensional distortion.
Could it be...
Yes, you are Nostradamus' Key.
More precisely, the Key is not you, but rather the act of you meeting your past self.
The reason you have lost your memories from that time is probably because of the shock it caused.
This isn't funny!
I found Nostradamus' Key and-
The future has not changed.
We are still invaded by aliens.
The future has... not changed?
That can't be!
Impossible...
Then, that time...
Bunmei!
She is Nostradamus' Key!
You were in that photo as well, Number Six.
That's what happened.
But don't worry.
Now that we are aware of the cause, all we have to do is avoid it.
We will teleport you immediately.
No, please wait...
Let me stay for one more day!
My mother is coming tomorrow.
At the very least, I want to see her.
There is still one more day before the 21st.
Please!
What should we do, Commander Kumashiro?
So that's why I never found it.
There is no way Nostradamus' Key was in the academy.
I knew that best.
If it were, then it would have had to be brought there after I left.
That's why I sent the agent after the funeral.
I never thought this act, itself, would be the cause of everything.
How ironic...
The future has not changed...
Meeting your younger self is Nostradamus' Key...
Such a thing...
Wait!
That means...
That means I was the one who-
No!
It's not your fault!
It is definitely not your fault.
Bunmei...
All I have to do is to not meet my younger self.
I also got a one-day extension, so at least I can see my mother.
That's all thanks to you.
But I can't attend the closing ceremony.
Just make up something to tell everybody.
There is a way for you to attend the closing ceremony.
July 20
Canceled?!
What do you mean?
You said it would go according to plan when we talked on the phone yesterday.
The circumstances have changed.
Please leave.
Leave?
We came all the way from Tokyo!
All the way to this remote dump of a place.
What's with that attitude?
What do you think my Fumiaki is?
This is such a creepy school after all.
You probably just wanted to use the performance to show off!
What's with you?
I'm just a teacher at this academy.
Pardon me,
but how exactly do you feel about your own son?
Don't you just see him as a tool to bring in money?
I will speak to my lawyer about this matter,
and soon enough will I demand compensation for my losses!
How's that?
If we make her that mad, she'll probably never come near Matsushiro again.
That was an amazing performance.
With this, you'll be able to attend the closing ceremony.
No, not just the closing ceremony.
If you want, you can stay here forever.
No, I really have to go back.
And I just realized now:
I don't have any good memories of my mother, but I still love her.
If I stay here, I'll want to meet her again.
I'll want to go to Tokyo.
Even if it is only a small chance, the risk of me meeting my younger self is...
Sorry.
It can't be helped.
Then for the last time, listen to what I say!
Principal's orders!
We're going home, Fumiaki!
What a terrible school!
We should have never come to a place like this.
I'm sorry, Fumiaki.
When we get to Tokyo, let's go to the planetarium together...
Fumiaki?
Fumiaki!
Now then, let's have a toast to Abe-sensei's upcoming journey.
Cheers!
Still, it's too bad you're resigning.
Why did you decide to quit?
It was my suggestion.
I told him that he was not suited to be a teacher, so why not look for some other career?
How harsh.
I was wondering what your last orders as the principal were...
What?
Be grateful that you're even getting a farewell party.
But it's true that he wasn't suited for it...
That's right.
Aren't you supposed to back me up here?!
I've always liked you though!
Like that time when you fought those little demons and we saved Ami...
When was that?
When you were sleeping beside the skeletons.
And that time when you jumped in front of the truck and told us to take you to Maya.
When was that?!
When you were bewitched, wielding a torch around.
Anyway, you don't know him at all, Dad.
He's typically irresolute and unreliable.
Is that all you can say?!
Also, he gets influenced easily.
He's cocky, yet irresponsible.
You talk like you're a big shot, but just recently you wet yourself and went, "Dad, I'm sorry!"
How long ago was that?!
Oh right! Maya-chan too...
At first, you really loved the occult, but when I saw you after a while, you were just hating it!
Still, I'm glad you're back to normal.
Anyway, the point is that everyone is different, and all of us change.
Right, Sensei?
Yeah.
You also had that right?
A time when you were naughty?
No, I...
Vega, Altair, Deneb!
It's the summer triangle!
This is the place for me!
I guess this is goodbye to this place.
Irresolute, eh...?
I really did just go along with everything.
Bunmei-kun! Bunmei-kun!
I wonder if I have ever walked my own path.
It's my fault.
It was my fault!
Right now, he must be...
July 21
I will be resigning due to personal reasons.
It was short-lived as it didn't even last a month,
but I'm happy I was able to spend it with everyone.
Don't be irresolute!
Don't be easily influenced either.
Of course, don't be cocky and irresponsible.
Hey, these are my lines...
Indeed.
Plant your feet firmly on the ground, and walk your own path.
This is my farewell to you.
That was the worst speech ever.
It can't be helped.
It's me we're talking about.
You got it all from Ami.
It can't be helped.
I don't want anyone to end up like me.
Do you hate yourself that much?
I don't want to lie to myself more than I already have.
I...
I love...
Well then.
This is Number Six.
Open the gate-
Wait, don't go!
The principal's orders are no longer in effect.
Don't go.
You shouldn't go.
Maya?
It can't be...
Did you come here by yourself?
Of your own volition?
I see.
That's fine.
From now on, keep walking your own path.
Stop!
Don't destroy my town!
Are you alright?
I'm borrowing this.
Bunmei, we have to get out of here.
History changes...
From here on!
Bunmei!
Maya!
Bunmei!
Maya!
I leave...
I leave it... to you!
Bunmei!
Bunmei...
We found the Key... and destroyed it.
Huh, where am I?
Stand up...
on your own feet.
Hey!
Everyone, come and see!
Maya...
Maya?
Is that you, Maya?
What?
What's the matter, Papa?
Did something happen?
Where are you now?
Well, I was having some tea.
I'll head home now.
That's great.
Fumiaki said that he will be home early today too.
Let's have dinner together.
Yeah...
Yeah, let's do that!
I'll be home soon!
Very soon.
I'm home.
Welcome back.
You're right on time.
Let's eat.
