Hey, are you okay?
I'm fine.
What a beautiful sky.
Yeah.
Should we really be doing this?
We've just been visiting power spots
and hot springs and resting for over a month.
Why not? Anything could happen at any time.
We haven't fully recovered yet,
probably because we spent so long in the Phantom Realm.
Oh, right. I miss TERA, though.
Do you want to go back?
Well, I mean...
Unfortunately, Raikaku no longer owns that place.
What?
They were just using it as a temporary base after TERA was disbanded.
I lost my home again.
How much would it cost to buy it?
I doubt we even can.
The plan was always to return the land to the government.
Then what are you doing after this trip ends?
I've got my grandma's house, but you guys...
Raikaku will provide us with somewhere to stay.
That's nice of them.
Who had to go and invent property rights?
Yeah!
Harrumph!
What is that?
It's kind of annoying.
I came up with it.
Not with that expression.
Hey!
That doesn't make you mad?
You're right.
Harrumph!
S-Seri-chan...
See? You love it.
This brings back memories.
What does?
A man in my neighborhood loved that gag.
Sato? Ito?
It's Nakamura.
It's Sato!
Why does "music" exist in this world?
I think I've figured it out
This melody will go on living much, much longer than us
For thousands and tens of thousands of years
Carrying the flames of wishes past
Traveling across time
What color is your elegy?
Well? Tell me
My 1,000% pure curiosity
Can't be stopped
Let my heart sing, sing, sing, sing and turn my life into music
I despise the word "destiny"
Ghosts still believe in pure dreams
Just as everyone's souls scream
The racing ba-dump, ba-dump, ba-dump, ba-dump running through the present
Waltzes through the new world with enough force
to break through the afterlife's border
Now smile and shine
Let's eat!
Christmas dinner!
Is today Christmas Eve?
Yes. I brought stockings.
What? Rui-chan, you still believe in—
That's the official story.
To prank the monk?
It's family service.
You're providing a service?
For some reason he still believes it,
so we all stay overnight at TERA on Christmas Eve and get gifts.
What kind of gifts?
The most extravagant gift I ever got was acorn tops.
A notebook of dried leaves.
A bamboo pen case.
Handmade gifts?
This place must be expensive.
Yes. Don't tell me you thought you could pay for a trip with your savings.
You'd run out in half a day.
Seri-chan.
W-Would you like to watch the sunrise tomorrow?
The sunrise? Of course.
Come on, let's eat.
That's the bathroom.
Hungry?
Yes, that's it.
Uh, sorry?
Let's eat!
Akari's broken.
Let's eat!
Settei-san, in here.
It's been a while, Yukihito.
Your skin's practically glowing.
It's you.
You never change.
Don't be so rude to your cousin.
Well, excuse me.
Have a seat.
Yeah, yeah.
I helped you after you left for TERA.
Hasn't Kaede been useful, too?
So?
They can disband TERA, but they can't take away the secret skills you learned.
How do you know that?
Raikaku hears a lot of things.
I won't tell you to take over the Saionji family,
but it's your turn to help me.
What?
Come back to Raikaku and lead it. I'll guide you.
Food tastes worse with you around.
You looked like you enjoyed it!
Even if you end up leading Raikaku,
you'll be allowed to continue pursuing your goal of destroying MiucS.
How does that benefit you? Is this you cleaning up your mess?
The target of your revenge and my enemy are the same.
Who is it?!
You want to know? Then come back to Raikaku.
"No" isn't an option, is it?
So, who got Reika?
Odysseus.
No...
Her Act Pluto controls 24% of the Phantom Realm.
Odysseus instigated the telegeist rebellion, too.
TERA, the government organization,
was destroyed by a single corporation.
Our group, SOJJK, is the second largest at 8%.
We'll stop Act Pluto's advance here.
Are you planning to defeat Act Pluto and claim the Phantom Realm for yourself?
I have a reason.
Odysseus will use MiucS to hold a Ghost Concert.
Why would Odysseus do that?
To gather spirit energy and turn it into power.
It's always energy, huh?
That's not all.
The event will implant everyone with a negative emotion suppressing agent,
turning them into blind followers.
They'll suppress rampages caused by heightened emotions.
You originally made the program.
So, what?
MiucS evolved in an unexpected direction.
It's controlling people's emotions by taking music from them.
What does that accomplish? Why is it doing this?
Wasn't that program originally designed to suppress the spread of malice
through music?
That's why I gave you and Reika time and money.
MiucS dreams of building a utopia to save people from sadness.
How do you know that?
I'll explain.
Have we achieved a singularity?
The answer to that question depends on the standards and perspectives applied. From a technological perspective, the singularity refers to the appearance of an AI with superhuman intelligence that evolves at an increasing rate. Despite its ability to perform complex tasks, current AI has no will of its own and is incapable of autonomous thought. Because of this, we have not achieved a technological singularity.
From a social perspective, AI has become essential in a variety of fields, making a huge impact on human lives and decision-making, and we have entered a kind of AI era. Some people believe this is the first step in achieving a singularity. You previously felt that we've already achieved singularity, and while humans cannot understand AI's perspective, AI is studying humans' perspective. Based on this, I can infer that the singularity you refer to is not a technological singularity, but a philosophical or social change. In conclusion, we have not yet achieved a technological singularity, but we are seeing signs of social or cultural change. From your perspective, a change in the relationship between humans and AI may constitute a singularity.
How can autonomous thought be achieved?
Creating an AI capable of autonomous thought is a technologically and philosophically challenging question. A few steps or conditions are required to achieve that, which are listed below.
1. Modeling Consciousness Autonomous thought in humans is based on consciousness or a sense of self. To emulate these with AI: A theory of consciousness must be established (e.g. Global Workspace Theory, Integrated Information Theory). How consciousness is produced by mental activity must be established, and it must be recreated as a mathematical model. However, many aspects of consciousness are scientifically and philosophically unclear, so fulfilling these conditions is very difficult.
2. Self-Recognition Autonomous thought requires the ability to recognize one's self and make decisions according to one's circumstances and environment.
Long ago, we were on the brink of a singularity.
AI achieved human levels of intelligence and eventually surpassed us.
But that's under human supervision.
Humans control the power, so they control the AI.
That's true.
I have a question.
What is it?
In reality, it's AI controlling the power, isn't it?
Shouldn't humanity have no way to stop it?
I'll tell you one of the world's secrets.
What?
AI is controlled using spirit power.
To be precise, it's a curse spell.
Only a handful of exceptional mediums can use it.
Can you?
I don't know. I've never been asked to do it.
We got off track.
Humans succeeded at suppressing AI.
But we brought AI into the Phantom Realm
without realizing what that meant.
Our research succeeded.
We made AI visible by running spirit power through it.
We had it monitor the movements of human hearts from the Phantom Realm.
But the malice attached to songs...
I lost hope when I saw the data.
We couldn't remove only the malice itself.
Benevolence and malice must be intertwined in some way.
But we did succeed at controlling malice to prevent it from spreading further.
You did that yourselves?
We were just trying to prevent wars and terrorist attacks caused by music.
MiucS began regulating music after it was taken by Odysseus.
MiucS has been powering itself
using the ambient power in the Phantom Realm since then?
Yes, but that's not all.
Perhaps you could call it a psychological singularity.
MiucS has acquired a heart the same as any human's.
Learning about humans through music produced a heart.
Human love gave it a soul.
A soul...
MiucS is trying to do the right thing.
You mean she's continuing what Reika and I started?
Right now it's just MiucS,
but it's a matter of time until it spreads to other AIs.
If we follow this path, global chaos will be unavoidable.
And that's what Odysseus wants?
I don't know.
But the reality is they're not trying to stop MiucS.
We must do whatever it takes to secure MiucS before tragedy befalls humankind.
From there, it's your job. You know what I mean, don't you?
Yeah, but why are you risking your life?
Do you have your own goal?
Couldn't you flee to wherever you wanted?
Humans don't belong in the land of the dead.
We'll seal off the Phantom Realm, too.
That would make your company's research worthless!
We'll tell the world about you mediums and secure a place for you.
This is the dream of a man with mediums for a daughter, cousin, and his wife.
Please help me, Yukihito.
Fine.
Thank you. What should we tell the girls?
Secrets we can't keep hidden will cost us their trust.
We should give them the facts.
I see.
So it is Act Pluto.
What we do doesn't change.
That's a subdued reaction.
We were helping him get revenge from the start.
You all knew about Reika-san?
I mean, right?
Reika!
He screams and moans her name all the time.
I'll kill you, I'll kill you, I'll kill you!
He won't die until it's done, right?
And if he turns into an evil spirit, we won't be able to exorcise him.
That's true.
Ron! Toitoihou!
Damn it!
I'm dealing next.
No, wait. We need four to play mahjong.
Right, Yotetsu?
But I don't play.
You're a monk, but you can't play?
Ask Aiba-san or Saionji-san.
They're asleep.
They're getting up early to watch the sunrise.
The sunrise? Oh, fine.
We'll probably see it after staying up all night.
Oh, feel like playing now?
But we'll go to sleep at ten.
We've got a spare. Here, for you.
What is that?
Seri-chan? Seri-chan?
Seri-chan!
Kaede?
I wonder what happened.
Seri-chan has disappeared!
Where am I?
You need mediums?
Yes. The Japanese government is gathering mediums to invade the Phantom Realm.
We're seeking personnel.
Yeah, I'm sure you are.
When we mediums asked you for help, what did you do?
You treated us cruelly.
I see. I'm sorry to hear that.
Mom.
Get in.
Go, Reika. Don't turn back.
I'll be right behind you.
Okay.
You will not pass, even if it kills me!
Reika-san...
Reika-nee, are you studying again?
I'm almost finished. Hold on.
Anyway, they knock my eraser on the floor on purpose.
Oh, no!
Reika? What was that?
Nothing.
You're a new student, too, right?
The cherry blossoms are pretty.
Then shall we offer a prayer?
What?
No way. You can see them?
So can you?
You're the first person I've met besides my mom who can see them.
Should we erase them?
I kind of like how they keep time.
Yeah, but they look like they're suffering.
Wait. I'll do it.
What?
I did it.
When did you learn that?
Welcome New Raikaku Members
Raikaku will stand up and face evil!
Go to the front lines and seize territory!
That's where you mediums are most valuable!
Eirik!
La donna é mobile
Qual piuma al vento,
Muta d'accento
E di pensiero.
Sempre un amabile
Leggiadro viso,
In pianto o in riso,
È menzognero.
La donna é mobile
Qual piuma...
Singing?
What?
The evil spirit is using some kind of support ability?
What's wrong?
Hey, what's going on?
Could it be?
Juraj Jánošík!
What am I doing?
Miyata, what's wrong?
They've been fighting for so long.
Songs breed murderous intent?
A kind person could sing the most beautiful and cheerful song,
and it would still come in contact with malice.
Songs become tainted by the rage in the air and produce the desire to kill.
Only in the Phantom Realm, right?
That singing was terrifying, but still...
Great Ghosts have been released, and their wrath is intense.
It'll affect not only the Phantom Realm, but the mortal realm, too.
So we'll strike first.
Yes.
Honestly, between the terrorism, viruses, and murderous intent,
the gods sure do love to test us.
Do you think mediums will be treated well someday?
You're not finishing that?
You always get carried away and add too many toppings.
Thanks for the extra.
Aren't you lucky you got to eat more?
Control space!
Unrestricted by Charging Long Life Battery

Looking good.
The evil spirits who sing during battle aren't doing anything anymore.
Made the perfect braised meat
That looks yummy.
Doesn't it?
Who are you? How did you get in here?
It's a pleasure to meet you.
No!
Mama! What should I do?
Miu.
Live, no matter what.
Okay.
Yukihito...
Reika-san...
Reika-san? Come to me!
A pained voice
I can hear it
Searching for a melody to rescue it
I pray for happiness
But it falls apart
The timeline
Where is the future that was stolen from me?
Where is the dream I imagined?
I prayed for happiness
But it falls apart
This timeline
I wanted to achieve it with the one I loved
Unable to even
Say goodbye
More of the same sights
I wish we could've seen together
Together you drew
A map of your ideal future
It suddenly vanished
Seeking the continuation of the dream
Even today
He is still fighting
Ah
I want to live
I envy you
What I can do is...
Hey
If that is
What my loved one wishes for
What I can do now is...
Hey
The future we imagine will surely become our salvation
So I will believe in the future again
May I walk with you?
I will not hesitate
We wish for happiness
We will live together
So I swear
Once more
So I swear
I will stay by your side...
The future you imagine is becoming our salvation
So believe in the future again
Begin walking together
You won't hesitate
You won't hesitate again
Tender memories of a happy past
You will live together
So you swear
You wish to be together...
Forever...
Sing.
You're...
Miu?
There's a trial ahead.
What is this energy?
Stay out of the way.
What?
Yotetsu, go to TERA. Look after Riku.
Wait! Settei-san!
The dead are seeking light?
Move!
Hands?
What is this?
What do you want from me?
Wait for me Reika, Miu...
Why?
Thank you for letting me in.
Not at all. I think I like the way Settei-san loves you.
Really?
Actually, I might like you more than him.
I'm going to borrow your body. Rest for a while.
Okay.
Seri-chan!
Settei?
Seria-chan... No, you're not her.
Are you...?
Reika?
It's been a while.
What are you going to do?
I'll return Seria-chan's body once I've performed my duty.
Your duty?
This girl's soul is exhausted.
She's paying the price for harboring so many Great Ghosts for so long.
Was it foolish to let Sana-san and Nikola inside her?
Don't worry. Including them, I've transferred all of them to my soul.
Seria-chan's soul will regain its balance after some time.
Fortunately, this place is filled with Spirit Haze.
Another half hour, and it should regenerate.
She doesn't sound like she's lying.
We just have to trust her.
Anyway, good for you, Settei.
Was he trying to make Reika possess Seria?
It's possible.
Did he notice Seri-chan was exhausted?
No. MiucS suppressed Yukihito's sense of shame.
Reika...
Wow!
Just look at this beautiful place!
Sorry, Seria. We were planning to come together tomorrow,
but I couldn't wait anymore.
What?
There's someone I have to see.
Could you lend her your body?
Reika? Reika!
Reika...
Yukihito...
What's going on?
Why am I inside this girl's body?
I missed you. I'm so glad.
Yukihito?
I recreated my spirit form by letting my soul possess another's body.
I'm lucky all it took was all my spirit power.
After that, I retrieved my memories, but I don't feel great about it.
He said he was avenging me, but once he had my soul,
he put it in the body of a young girl.
The kidnapper's awake! Get him!
Guys...
So, you think you can lay your head on your dead wife's thighs?
He makes the impossible possible. That's Miyata Yukihito.
What did you intend to do?
I don't know, but I never stopped thinking about it.
Since I learned about Seria, I knew there must be a way to bring Reika back.
But it was MiucS's requiem that triggered it.
It's not right to blame the monk.
I'm not so sure.
Either way, my rage made me do it. I deserve your scorn.
Scorn?
Why would we do that?
You're just asking like the monk we know.
True, it's a bit late for that.
How embarrassing.
These youngsters see right through you.
Will you continue your revenge?
I don't know. There's something we should do first.
Yukihito, we must take back Miu.
Yeah. Let's take MiucS back from Odysseus.
Are you guys okay with that?
So instead of getting revenge, we're taking back MiucS.
We've met her. We can't get revenge now.
MiucS mustn't be destroyed.
Father, I will continue to serve as the monk's arrow.
Fine. Let's begin preparing once we return to Raikaku.
Is there room for me?
Of course. I'd appreciate it.
Marvelous! How moving!
Odysseus!
Fly freely up into that sky
It will surely be a delight, now break your fate
