2019.

Humanity faces imminent destruction.

Founded 1979

But soon it will tell a story about the heroes that put their lives on the line to prevent said destruction.

Dimension High School

I mean, it's literally just started.

This rock...

This seemingly plain, unassuming rock...

is incredibly important to this story.

Not really the best...

It's not a meteorite.

Actually, it's kinda nice.

And so, the countdown to the destruction of humanity began.

Class 3-D

Let's go over the Doppler effect one more time.

TUTORING

Episode 1: Brain-Blasting Genius

When an ambulance rushes past...

Sound frequency does not change, even when the source moves. Speed of sound never changes, even when the source is moving. Doppler Effect

...the sound of its sirens changes, right?

As it approaches, the sirens sound high in pitch,

but when it passes, it suddenly sounds much lower.

Think: Why would the sound change like that?

There are two things we have to remember.

Source Source isn't moving Source Source is moving

First: the frequency of the sound never changes

no matter how quickly the source might be moving.

Second: the speed of sound never changes no matter how quickly the source of the sound might be moving.

Keep those two facts in mind as we move on.

What is it that changes, then, when the source of the sound moves?

The answer is the wavelength.

As the source of the sound comes closer, the sound waves get shorter.

Conversely, when the source of the sound moves further away, the sound waves get longer.

Hey, you okay, Yurio? Conversely, when the source of the sound moves further away, the sound waves get longer.

Yeah, it's just the usual.

Yeah, it's just the usual. We hear shorter sound waves as higher pitched, and longer sound waves and lower pitched.

No, man, that sounded totally different! We hear shorter sound waves as higher pitched,

and longer sound waves and lower pitched.

Should you see the nurse? Should I call an ambulance?! We hear shorter sound waves as higher pitched, and longer sound waves and lower pitched.

Will you pipe down over there?

Will you pipe down over there? That's why the sound of the sirens changes as the ambulance drives by.

Maybe you should listen to Momoya-sensei! That's why the sound of the sirens changes as the ambulance drives by.

What? That's why the sound of the sirens changes

as the ambulance drives by.

If you're not feeling well, then go see the nurse.

If you're not feeling well, then go see the nurse. Let's dive a bit deeper into why the Doppler effect happens.

Let's dive a bit deeper into why the Doppler effect happens.

What are you staying here for? Are you stupid? Let's dive a bit deeper into why the Doppler effect happens.

Oh, right, you're staying here for tutoring because you're stupid.

My apologies.

You're here, too!

Unlike some of us here, I wasn't held back a grade. My grades are stellar, actually.

I just don't want to miss one of Momoya-sensei's physics lessons.

Please don't lump me in with the lot of you.

I don't get you, man.

Huh? What?!

Shiroyama-kun.

Quiet, please.

Uh, no, it was...

...this thing?

Be quiet!

What's the matter, Shiroyama-kun?

Oh, nothing! Nothing's the matter!

What the hell?

Is that a magic trick?

Hey, Yurio, check this out!

Yeah? What is it?

Wait, is it floating?!

That's awesome!

Cool!

Are you doing this, Shiroyama-kun?

Will you please cut it out already?

Shiroyama, why are you doing magic tricks? We're in the middle of tutoring!

It's not a magic trick, really!

Stop messing around!

Is everything alright?

Of course, Sensei. Everything's alright. We'll get right back to work on those printouts.

Oh, okay.

Yup!

Get back to work. Come on!

That's totally two-faced, man.

This is...

physically impossible...

Hey, now! Hey, now!

I ain't any kind of magic trick, y'hear? So don't go getting scared!

You all came into contact with me, and as such, you must be the prophesized heroes.

Oh, how long I've waited for this moment!

I am Spudio the 22nd!

I need your unique abilities.

You must defeat the terrifying demon of destruction!

If you don't, you humans are all doomed!

Whoa, wait, hold on!

Hey, now, hey!

What the hell was that?

Shiroyama-kun?

Some horrible prank.

There's a camera in there taking footage of us freaking out about it.

Someone out there's probably laughing at us.

This isn't funny, it's just mean.

It was floating, though...

It must've been some kind of new drone, or a floating toy someone came up with to prank us.

Well, you're depressing.

There isn't a single good thing in this world of ours.

Even when you try to take care of a basil plant, it always gets destroyed by some kind of insect.

Must be a fierce battle...

I want tutoring to be over so I can go home. I need to water my plants.

Hey, now! Hey, now!

You threw me out that goddamn window, didn't ya?!

I've never been treated so rudely in my life!

I was trying to ease you into this, but that's all out the window now!

Fine then, prepare yourselves!

I'll take you there by force!

Wait, what? Is this some kind of anime?

Huh? Hold on, what?

Who are you?!

Oh, I'm Shiroyama.

Shiroyama-kun?

No way! Why do you look so anime?

I wish I knew.

Wait, are you...

Mizukami-kun?

Yeah, you recognize me?

Kind of.

So the other guys here must be...

Yeah...

Am I dreaming? Hold up a sec!

Kikawada-kun!

Huh? Yurio?!

You recognize me?

Of course I do!

What is this, some kinda manga?

Come on, this is an anime.

Is this...

I wasn't sleeping, I swear!

Ryusei Midorigaoka, I assume?

Yeah...

Huh?

What the hell?!

It's me, Junpei Shiroyama.

Shiroyama?

A-am I dreaming?

Why are you in my dream?

Oh no, am I subconsciously interested in you or something?

No, no! No freaking way!

We've known each other forever, though.

Go away, go away!

Wow, rude.

Um, is this...

I see, this is a dream, then?

Sensei! Momoya-sensei, right?!

It's me, Midorigaoka!

I can't believe we're in the same dream!

It's an honor, Sir!

I see how it is.

Holy shit, my hands!

What? Nothing's happening.

Does that mean...

Stop, Junpei! Don't wave your hand around in my chest!

N-nothing happens...

Yes, nothing happens, so stop it!

It's not just happening to Ryusei.

Does this mean we can use special powers here or something?

Special powers? Sweet!

This is completely impossible.

That means that we must be in a dream.

Of course!

A dream? You really think so?

Hey, now! Hey, now! This ain't no dream!

You're that rock!

I'm no rock!

I'm Spudio the 22nd! Didn't you hear me the first time?!

Spu... Spoon?

Spudio the 22nd!

Why is this rock talking?!

I may look like a rock, but I'm a living being, just like you.

We've got ourselves a convenient, talking pet mascot!

I wish you were cuter, though!

Like one with a long tail, or one you can just pop the head off for fun.

You're scaring me.

Hey, I have to ask...

Where are we?

This is a different world than your three-dimensional home:

the two-dimensional world.

Look out the window.

This world is on the verge of collapse, thanks to the Demon of Destruction's attacks.

This classroom is the only place in this dimension that has escaped destruction.

Your anime-like forms are a result of your rebirth in this world.

Watch out, Yurio. Your anime-like forms are a result of your rebirth in this world.

Right. Your anime-like forms are a result of your rebirth in this world.

Those forms will enable the four of you to defeat the Demon of Destruction!

Yes, you four are the chosen heroes!

There are five of us, though.

What?

One, two, three, four, five.

Five of us.

WHAT?!

What does this mean?

It was supposed to be four, right?

Something's off...

"Chosen heroes"? "Demon of Destruction"?

Sounds like a video game.

Wait, you actually understood what he was saying?

Don't lump me in with you idiots. I'm smart, even in my dreams.

What?!

This door won't open.

Huh?

It's locked.

So we're trapped in here?!

Taste my ironclad tackle!

Dammit, it won't budge!

The hell is an "ironclad tackle"?

The windows won't open, either.

We're completely sealed in.

What's going to happen to us?

Take us back to our world!

I don't have the energy to take you back.

It took everything I had to bring you here.

So, we're stuck here?!

You've gotta be shittin' us!

Look, I can't bring you back, but I know a way to get you back!

Well jeez, out with it already!

An earthquake?!

He's coming!

What now?!

Hello, there!

My name is Sphinx Paramesos.

Welcome, Denizens of the 3D World!

Great to have you here.

So hey, I've gotta ask, do you like solving puzzles?

Me, I love puzzles!

On that note, I'm going to have you solve a few of my puzzles!

If you follow my rules and get the right answer, I'll let you go.

Huh?

Solving puzzles?

Rules?

You'll let us go?

You mean we can go back to the real world?

Everything is happening so fast, I can't keep up.

You've got to solve these puzzles!

This is your battle, noble heroes!

Okay, then, question one!

Question How do you read this? Answer

How do you read this?

You have one minute!

One minute?

That's impossible!

I've never seen letters like this before! How am I supposed to read 'em?

This dream is quite intellectual. I certainly don't dislike that aspect.

C'mon, first we're in an anime, now we're solving puzzles?

This is crazy.

You have to solve the puzzle, or something terrible will happen!

What kind of terrible thing will happen?!

In any case, we've got to solve this puzzle.

It must be four characters long.

You're so positive about this! That's why I like you, Momoya-sensei!

Hey, it looks like the character for "mountain".

Yeah, it might be "yama"!

How does it look like "yama"? It's concave.

They do look a bit like kanji.

Yes! They must be kanji!

Four kanji in a row...

A Japanese name with "yama"...

Yamada Takeyuki!

Yamadera Kouichi!

Yamagata Kenmi!

Yamaguchi Kenmi!

Don't copy my answers!

The third one kind of looks like "ten", right? Like the "ten" in "tengoku".

(Ten-ka-tou-itsu) "Unify the country"?

Oda Nobunaga!

Toyotomi Hideyoshi.

Akechi Mitsuhide!

Sanada Yukimura!

Oyakata-sama!

Yokoyama Mitsuteru!

That's a mangaka.

Maybe it's not kanji, but English letters...

That's time!

So sorry, but time's up!

The correct answer was...

"TIME"!

The symbols appear to be based off of a box crossed by eight lines.

However, each of the symbols is missing parts of that base, right?

But... if you take those missing parts, you get TIME!

Shit! It was so easy!

I could've gotten it if we'd had more time.

Boy, is that unfortunate!

None of you gave the correct answer.

So, I'm going to take one of you!

"Take"?

Let's see who's the most mature...

Locked on!

S-Sensei!

Boy, he sure was tasty!

He was perfectly soft, and right after I bit into him, this wonderful umami flavor just flooded my taste buds!

Wow! I'm so glad to be alive!

Three-dimensional humans are truly exquisite!

Sensei?

He's not breathing!

No way!

This can't be happening...

Sensei! Sensei!

I told you, didn't I?!

You gotta work hard and solve those puzzles, or he'll eat you!

He's going to freakin' eat us?!

Okay, next puzzle! Question number two!

What?!

There are more?!

Come on, you guys. You've gotta solve this one!

You've got three minutes for this one!

SHOES goes to BASE?

SUMMER goes to LAND?

IRON goes to what?

SOIL.

The hell is soil?

"Tsuchi", like dirt.

What do those squiggly lines at the top mean?

Iron goes to dirt...

Iron?

Wait, like "tetsu", the metal? So "tetsu" goes to "tsuchi"?

Um...

Aw man, I have no idea! Shit!

This is bad!

We're all gonna get eaten at this rate!

We ain't lettin' that happen!

Squiggly lines...

A spring? Waves?

Wavelengths?

Question Answer

We were just learning about wavelengths, right?

Do you think it has something to do with the Doppler effect?

The ones on the left are long, and the ones on the right are short...

So the wavelengths are different...

The wavelengths are different...

What happens when the wavelengths are different?

Like, when an ambulance goes by, the siren sounds higher pitched when it comes closer,

and lower pitched when it gets far away.

Sound frequency does not change, even when the source moves. Speed of sound never changes, even when the source is moving. Doppler Effect

Source Source isn't moving Source Source is moving

Oh! That's what this is!

It's just like the Doppler effect when the source of a sound moves!

Huh?

What?

What does that mean?

Longer waves have shorter sounds, and shorter waves have higher sounds.

That means that the left is "higher" than the right.

"Higher" as in one step up in the Japanese alphabet!

"Na" and "tsu", of "natsu", SUMMER, are one step below "to" and "chi", of "tochi", LAND.

Oh, so that means one step above shoes, "kutsu"...

"Kichi", which is "BASE" in Japanese!

So IRON and SOIL are "tetsu" and "tsuchi"!

You're runnin' out of time!

STONE is "ishi" in Japanese...

5 seconds left!

Got it! "Asa"!

The correct answer is MORNING!

Whoa, no way!

You got it right?

That wasn't supposed to happen!

Sensei, you're okay!

Where are we?

We're back at school. Are you alright?

Midorigaoka-kun...

Everyone else made it out alright, too!

Do you guys remember what happened to us?

I had this weird-ass dream...

It was seriously messed up! You guys were there, too!

A mass hallucination?

That's crazy...

In any case, we made it back...

Shiroyama...

You're a frickin' genius, man! I can't believe you knew the answer!

Boy, am I glad you didn't get eaten!

I just had this brain blast...

Yeah, you're a brain-blastin' genius!

Yeah!

I mean, I knew the answer, too.

Yeah, right...

What a coincidence...

I sure am glad we were learning about the Doppler effect!

Seriously, though, what was that all about?

I've never heard of a whole group of people having the same dream.

Hey, now! Hey, now!

I told ya, it ain't a dream!

Not again!

Listen up, your trans-dimensional battle has only just begun!

What's that supposed to mean?!

By the way, Sensei, you okay?

You did get eaten...

Oh, yes, I'm alright.

I'm not injured or anything.

I see...

You sure you're okay?

What? Out with it!

You're gonna freak him out!

Well, the Sphinx has this rule...

If you get eaten and are revived, you will lose the one thing most precious to you.

Hey, wait, hold on!

Don't you come back! Hey, now! Hey, now!

No!

The one thing most precious to me...

N-no... No!

Sensei!

All the money I earned in Date Raid...

I-it's gone...

My money!

The money I busted my ass to earn between classes!

Give it back! Give me back my money!

Where is that no-good rock?!

Where the hell is he?!

I'll grind you to dust!

You glorified piece of shit!

Momoya-sensei...

Need a hand, Ryusei?

Don't think you can start using my first name, Shiroyama.

Sorry...

I used up all my energy...

The Sphinx will be back.

Prepare yourselves...

The one thing most precious to me...

And so, the countdown to humanity's destruction began.

What lies in your future?

Will you be able to solve the puzzles?

Use your brain while you still can!

The one thing most precious to me...

You bastard!

What are you using Momoya-sensei's energy for?!

We need an idea that'll help us get to the right answer!

Do you want to die?!
