A civil war has erupted over the incredible energy hidden within Pandora's Box.
SEITO
HOKUTO
TOUTO
Kamen Rider Build aka Kiryuu Sento attempts to fight off
an invasion by Seito, currently taken over by Nanba Heavy Industries.
He heads to retrieve Pandora's Box, and end the war, but then...
My name is...
You're the Queen of Mars?!
Everyone's idol, Miitan!
Quit trying to capitalize on the plot twist about the queen to get laughs!
Now, what'll happen on Episode 31?!
Banjou...
He might not be human.
We'll have to do this...
GEAR ENGINE!
FUNKY MATCH!
Mistify.
What do you mean, he might not be human?
It's not really clear yet, but... I'd say the chances seem pretty high.
What happened to him?
What's going on here?!
We're outside all of a sudden!
It's like some kind of magic trick.
Did Pandora's Box cause this?
It's been ten years since the Sky Wall Disaster.
In order to open Pandora's Box,
which contains an immense power that could destroy the world,
a new battle now begins!
I'm going to keep walking on tonight
Moving on straight ahead
Leaving only a single set of footprints ahead of me
It seems so vast, but I get the feeling you're out there
Waiting for me somewhere
With a smile that never fades
There you will...
Be the one, be the one
All right!
Who'll never give up on the Earth's future
Be the light, be the light
All right!
You can be stronger
Love will never lose!
Helping, saving, and embracing
Touching our hearts so that it can reach out
Be the one, be the light
Send this message and let it ring out!
Surging Magma!
DANGER!
CROCODILE!
Transform.
CRUSHED! CONSUMED! CRACKING!
CROCODILE IN ROGUE!
I'll take him!
You've gotten stronger again.
Shut up! Don't think I've forgotten...
What you did to Kasumi!
Ryuuga, is that you?! Help me!
She died because of you!
That rage of yours is what Stalk is looking for...
He wants you to become stronger, more than anything else.
Increasing your Hazard Level requires an extreme emotional response.
That's why the girl ended up dead.
You're saying Stalk was behind it all?!
Your growth is a part of Stalk's plan.
READY, GO!
DRACONIC FINISH!
Kasumi was killed...
Just to raise my Hazard Level...?
I talked to a lot of people when I was looking into Banjou's background,
and they were hesitant to talk, or didn't want to at all.
Since I didn't have any other leads, I looked into the OB-GYN records.
How did you get those records?
You're... better off not knowing.
So...
It turns out those records had been sent to the Nanba Heavy Industries General Research Lab.
Isn't that where Pandora's Box was originally being researched?
No Trespassing Closed by Management
Right. The government and Nanba were collaborating on the research.
Nanba Heavy Industries General Research Lab
And Banjou was one of the research subjects.
What do you mean?
This is Banjou's mother.
Ms. Banjou!
Yes?
Her name was Banjou Yuri.
Yes...
She and her husband both worked at a security firm.
One of their clients was the Nanba Heavy Industries General Research Lab.
The manned mission to Mars landed 10 years ago, remember?
But there was also an unmanned probe that landed 23 years ago.
It was big national news at the time.
After the unmanned probe made its way back to Japan,
Banjou's mother was in charge of its security.
But...
One day when she was on duty, she fainted all of a sudden.
Just like what happened to me...
Yeah.
When they examined her at the hospital,
they found out she was one month pregnant.
They thought that was why she lost consciousness, at the time...
But it wasn't?
Her child was born a month later.
Okay, here we go!
And he was incredibly healthy.
That was Banjou.
Wait a minute!
She gave birth just after two months?
That's impossible.
It really is...
And after Banjou was examined at a university hospital,
they discovered cellular material unlike anything ever seen before.
Afterwards, they took him to the Nanba General Research Lab for further examination...
These are the test results and research data they gathered from him.
And how'd you get that data?
You're... better off not knowing.
IT'S A FULL FULL MATCH!
FULL FULL MATCH BREAK!
RABBIT!
RABBITRABBIT!
Rogue!
SO FAST!
IT'S A FULL FULL MATCH!
Shut up and listen to me.
Right now, Seito's PM isn't Midou.
Nanba's just wearing his face.
I wanted to use Pandora's Box as a deterrent to unify the country again.
But Nanba has other plans.
He wants to use its power to rule the world.
You have to take it before they open it.
Why are you telling me this?
They implanted a chip in my body.
If they get suspicious about me, they can kill me at any time.
If you understand...
Now take me out!
CRACK UP FINISH!
FULL FULL MATCH BREAK!
You alright?
You have to take it before they open it.
President Nanba is disguised as Midou?
Yeah. If we can believe Rogue, anyway.
But why would he tell us?
I'm not sure.
A dead end?
Glad you could make it.
You boys are after this, right?
And what I want is those bottles you brought with you.
Once I have those, I can open this.
What a thrill!
RABBIT!
Transform!
ARE YOU READY?
OVERFLOW!
RABBITRABBIT!
ROBOT IN GREASE!
GET CROSS-Z DRAGON!
YEAH!
OH NO! SO FAST!
These are Nanba Heavy Industries' latest weapons.
Clone Smashes, that don't require a human body.
Now then...
I guess we should get started, too.
The Transteam System is little more than a wardrobe to me.
Even without it, I could beat you!
It's not working?
Oh, I forgot to mention...
Those things have no sense of pain. They fight until they're dead.
What?!
TANK!
What do you really want?!
Did you really kill Kasumi just to make me stronger?!
Rogue told you, huh?
Him and his big mouth...
Just answer me, dammit!
That's exactly it!
Your strength is what I am truly after.
But... you're not there yet!
What was that...?
Stalk!
Trying to ape Cross-Z's style, huh?
But you don't have what it takes, either!
Kazumin!
He can control Pandora's Box?!
This is my power!
Looks like it's true.
They found non-human DNA when they examined Banjou.
What do you mean, non-human?
It's of extraterrestrial origin...
He has alien DNA.
This is just me speculating,
but this could be similar to your situation.
Some kind of alien life form rode the unmanned probe to Earth,
and Banjou's mother became the host for it.
And since she was pregnant with Banjou, it moved onto him...
It looks like Banjou got checkups regularly
at the Nanba General Research Lab, until his parents died.
But he never mentioned that.
Yeah...
The researchers may have kept the true point of the visits a secret,
or they might have done something to alter his memory.
Banjou!
Is this really all you can manage?
Don't!
It's not, is it?
Sento...
Taking that hit at close range...
You sure have got a death wish.
Well, if you insist...
I'll grant your wish, and kill you.
And once again...
You'll have to watch someone you care about die before your eyes.
Why... can't I move...?!
Why can't I stand up?!
He believed in me, dammit...
He gave me a future...!
And now...
I can't do anything... again?
Is this it...?
Is this all I can do?
Hell no...
It's not!
There you go...
Attaboy, Banjou!
Banjou! Load it into the Knuckle!
BOTTLE BURN!
CROSS-Z MAGMA!
ARE YOU READY?
Transform!
ARE YOU READY?
Transform!
RED-HOT MUSCLES!
CROSS-Z MAGMA!
Cross-Z Magma.
HOTHOTHOTHOT!
I feel power overflowing...
My soul is on fire...
My magma is surging!
No one can stop me now!
Very good, Banjou.
Show me what you can do when you're serious!
You asked for it!
Right now, I get the feeling I can't lose!
READY, GO!
VOLCANIC ATTACK!
SO HOT!
Hot! Damn, that's hot!
Yo, this is really hot! Ow!
Banjou, get Pandora's Box!
Hot!
Hothothot! Ow!
I won't let you have it...
Hot!
Whoa, hey...
It transformed...
I don't know what's going on, but let's go!
Hey, wake up, Dorkazumi!
The vessel is finally ready...
Now I just need the ultimate Driver,
and everything will be in place.
What are you doing? Come on!
Where are we?
Man, you didn't see all that? I was badass.
Cross-Z Magma is unstoppable, dude.
And talk is cheap.
Say what?
Who do you think just saved you?!
Hey, cut it out!
Tap out, Kazumin!
How was he able to control Pandora's Box?
I'm not tapping!
Tap out!
Hey, look here!
The person who was in charge of studying Banjou...
Katsuragi Shinobu
Katsuragi...
Shinobu.
Katsuragi Takumi's...
Sento's...
Father.
Kamen Rider Build!

What the hell do you mean, I'm not human?!
What plot was Sento's father a part of?
I never would've thought my father was studying him...
What plot was Sento's father a part of?
Your power is the same as mine.
Will Banjou destroy the world...?
The kind that can end the world.
Will Banjou destroy the world...?
A Pre-Programmed Tragedy
