Next, put this string over this finger...

Done.

There she is. Hello, Miku. We're here to visit.

Hey, are you playing cat's cradle?
And you've gotten pretty good at it, haven't you?

Mizuki, you taught her how to play, right?
She was playing it when I visited the other day, too.

Wow... Is that a Jacob's ladder?
That's an advanced move for cat's cradle. You must've been practicing.

Yes, I have a lot of time.

I see! Well, I'm just glad that you're having fun with it♪

...

What's the matter?

Mafuyu's not here.

Did something happen?

Ah... Mafuyu couldn't make it today because she has cram school. It's just us today.

Oh. That's good to know.

Anyway, Mafuyu told us something new has appeared in this SEKAI. Can you show us what it is?

Something new...

I think...it was a marionette?

You mean, this?

Oh wow, it's so cute!

It really is something new...
We've never seen this here before, right?

Yup! If we had, I would definitely have noticed it!

This marionette has always been in this SEKAI.

How so?

So...it's not something new that showed up because Mafuyu went to a doll exhibition and was influenced by it?

No.

Mafuyu was ignoring it, but this marionette has always been in this SEKAI.

Which means...this puppet became visible when Mafuyu decided to notice it?

Maybe. Something must have changed inside Mafuyu.

Changed, huh...

Wait. Does that mean it's possible there's actually a lot of other things here right now, just that we can't see them?

Oh...then we may be able to find some clues about how to create a song that will save Mafuyu here.

I don't think you can...

Why not?

It's possible that only Mafuyu...the owner of this SEKAI's feelings, can find anything that's been hidden here.

Just like how nobody was able to find this marionette... Not even Mafuyu herself.

Oh..

So basically, it's not going to be easy for us to find something even Mafuyu herself can't see, huh?

Um, so coming here wouldn't help at all, then?

No. It does help.

But...

You've already helped Mafuyu to make big changes.

Remember... This place used to be a Empty SEKAI.

Oh...

She never used to let anybody into this SEKAI.
But now...you're all here.

You all have a place in Mafuyu's heart.

We have a place in...

Hehe, you have no idea how happy I am to hear that!

You're welcome.

It doesn't feel that way to me at all, though.

Maybe it's just that Mafuyu hasn't noticed it herself, yet?

So please keep looking for Mafuyu together with her, now and in the future.

You have my word. I'll definitely save her.

Yup! We'll fill this SEKAI up with all sorts of different things, like this marionette!

Eh, I wouldn't mind a less pesky version of her, I guess.

Again, Enanan? Just be honest with yourself already!

Whoa! It's already 25:00!
Mafuyu should be back by now.

Yes, she's probably waiting for us.
We should head back.

Just one last thing...this is a marionette puppet, right? Why doesn't it have strings?

I'm using its strings to play cat's cradle.

Oh... Hehe. Of course.
