In order to take over the nation, the extraterrestrial entity Evolt
has begun gathering 10 Lost Bottles, extracted from ten powerful monsters, the Lost Smashes.
Kamen Rider Build aka Kiryuu Sento is searching for his father, Shinobu, creator of the bottles...
Gentoku! Why do you keep choosing clothes like that?!
Why can't you accept my amazing fashion sense?
Miitan, can you help me coordinate my outfits?
Kazumin, if you want Miitan's help, that'll be a million dollarks.
Man, I'm starved! Time for some protein!
And that's enough of that.
Look, things have been going crazy while you guys were occupied.
So pay attention, before we get into Episode 42.
Never knew all that crap was going on without us...
To think that Evolt would start to have human emotions...
How ironic, though, that he's becoming more human...
What about the Lost Bottles?
He took them. I'm sorry.
Nothing you could do. We just gotta take them back.
Were you able to find out any new intel?
Shimizu said he was my father's assistant.
He's gathering the Lost Bottles to build the black Pandora Panel...
A black Pandora Panel...
Doesn't ring a bell.
Hang on.
If Evolt is gathering the bottles needed for one of those black panels...
Sento's dad might be with Evolt.
Just four more Lost Bottles, and the the door to a new world opens.
Why kill Shimizu?
I thought he could've shared a bit too much to the enemy.
I only kept him alive because he was valuable as a potential Lost Smash.
But now that I've got the bottles, we're done with him.
Except that there are no other subjects who can become Lost Smashes.
Then we'll just experiment with the Kamen Riders.
That's true. They potentially fill the requirements to become Lost Smashes.
But considering that Build's Genius Form might make him incompatible with Lost Bottles,
we can't be certain.
Well, then it's your job to figure something out, doc!
Let's speed up the timetable to produce more Lost Smashes!
And for that...
I've got a nation to unite!
Pandora's Box, which contains enough energy to destroy the Earth, has finally been opened!
Standing up to Evolt, the extraterrestrial life form that has gained its power,
are the Kamen Riders!
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!
There's nothing that points to what's going on with Dad...
So there's no proof your old man's one of the good guys.
Legacy of Doubt
What's that supposed to mean?
Maybe he and Evolt are working together. Willingly.
What?!
Worst case scenario...
He might even be the mastermind.
That's impossible!
Then why didn't he ever come and see you?!
Give it a rest!
We gotta figure out if he's even alive, first.
There's a chance that Evolt might've taken his identity.
This is the Touto government office!
Seito's forces are currently attacking this office, and area A!
Evolt!
Guess I get to play with you boys today.
Is my Dad alive?
What are you on about?
Don't play dumb!
You know where he is, don't you?!
Where is he?! Tell me!
Protecting Touto comes first.
DANGER!
GREAT!
ALL YEAH! GENIUS!
CROCODILE!
ARE YOU READY?
Transform!
Someone's acting rather emotional today!
Shut up! Where's my Dad?!
Answer me!
More worried about daddy than Touto, huh?
FULLBOTTLE!
Try this on for size!
STEAM ATTACK!
It's showtime!
READY, GO!
BLACK HOLE FINISH!
CIAO!
What is that...?!
A black hole...
What's going on?!
It happened again...
Why do I...?!
I can't control it...!
Where'd this power come from?
Smash you...
I'm gonna smash you!
A bottle turned silver?
BOTTLE BURN!
VOLCANIC ATTACK!
How did his power increase so suddenly?!
Very good! Keep going!
The government office...
And with that, Touto is done!
The country belongs to me!
Ciao!
Dad's Touto...
Wait!
Hey.
Hey, that's enough, man!
Shut up! Get off!
I said stop, dammit!
NINNINCOMIC!
CONCEALMENT SKILL!
What is this?!
RABBITTANK!
Hey, Ryuuga!
What happened?
What just happened, man?!
Hey!
Someone attacked me...
Was that...?
Get up. Come on!
A bottle that shines...
Hazard Level 7?
Today marks the end of this prolonged war, that's seen so many casualties on all sides.
At last, our country stands united.
And it is our desire that our country never repeats such tragic events ever again.
Hey! You gotta see this!
Come on, get over here!
To that end, I have reconsidered certain things.
In the future, we will withdraw all weapons, except those used for self-defense.
Hooray!
In order to reunite all our hearts, which were divided by the Sky Wall....
I, Midou, whatever my faults may be,
Broadcasting Live To All Three Capital Cities
will work to build a new Japan!
This Midou is just Evolt, right?
What a load of crap.
Everyone's excited about the country being reunited.
But there's not a good thing about it.
We're still just livestock for Evolt.
If we don't do something, he's gonna do whatever he wants with us.
...a government where our number one concern is the people!
And with that, the whole country is under my control.
Now we need to get those Lost Smashes.
Put everything we have into procuring the Kamen Riders.
If we mass produce Lost Smashes and have them attack people,
the country will be destroyed.
If domination is your objective, isn't that a contradiction?!
What are you really—
Don't ask questions if you're not ready for the answer.
If you value your life, that is.
The country...
And Dad.
We never run out of things to worry about, do we?
Where is this...?
A world based on our memories.
Katsuragi Takumi...
I'm controlling them from here.
What...?
So you're the reason my memories from the "Devil's Scientist" days are vague?
That doesn't matter.
What are you going to do next?
It should be obvious.
Find Dad, and work with him to stop Evolt.
You still believe in him?
Of course I do.
He designed the Rider System in order to defeat Evolt.
You completed it because you thought it was the right thing to do.
The right thing...?
I honestly hope that's the case.
Gen...
My Dad told me...
That a nation isn't made only by those who hold power, or its authorities.
That it's made by its people.
I was so proud of him.
But, now, instead of repaying him...
I wasn't able to do a single thing to live up to his memory.
Even though the last thing he did was entrust this country to me...
I couldn't do anything.
It's the same with me.
Dad entrusted me with the Rider System so I could beat Evolt...
But I still haven't been able to do it.
Kamen Riders form anti-government insurrection
We've got breaking news.
The Kamen Riders of Touto, Seito, and Hokuto have formed an insurrectionary force
in response to the new government, and are rioting in a Touto city.
I repeat...
Sento, look!
Kamen Riders form anti-government insurrection
They're making us Kamen Riders the rebels who stand against the country.
There's an anti-government attack in area B, too.
We urge viewers to stay indoors.
Breaking News - Anti-government Uprising in Touto Area B
This is probably a trap to lure us out.
But we're not gonna ignore it just because of that, right?
Of course not.
You guys take Area B.
Right.
We'll head to Area E.
Hey, that's enough!
What do you think you're doing?!
Our objective is to capture the Kamen Riders.
We'll turn you into Lost Smashes!
That's not going to happen!
GREAT! DANGER!
ALL YEAH! GENIUS!
YEAH! YEAH! YEAH! YEAH!
CROCODILE!
ARE YOU READY?
Transform.
BUILD GENIUS!
AWESOME!
REALLY AWESOME!
In the end, you couldn't fulfill your father's will!
Poor Prime Minister Himuro...
To think he gave his life for such a useless son!
He actually died for nothing!
You can beg forgiveness when you see him!
READY, GO!
EVOLTECH ATTACK!
CIAO!
Gen!
This country belongs to Evolt!
And if you try to oppose us, that makes you the rebels!
RIFLE MODE!
FUNKY!
READY, GO!
EVOLTECH ATTACK!
CIAO!
What is the point of turning this whole country against you?
Nobody needs Kamen Riders!
Evolt can't take the future we want away from us.
There's worth and value on fighting for it.
For the people who believed in us, and entrusted us with that future!
We can't go down like this!
I'm counting on you... my foolish son...
You're right.
I won't let it end like this.
To defeat Evolt...
To rebuild this country...
I will dedicate everything I have to fulfilling my duty!
Kamen Riders will never yield.
Gen...
I've got all the data I need to counter your movements!
CROCODILE!
READY, GO!
What?!
You can't beat us!
Why? The readings can't keep up...
The Rider System can't be measured in pure data.
Our desire to help other people makes us stronger!
I feel power overflowing...
My soul is on fire...
My magma is surging!
No one can stop me now!
READY, GO!
VOLCANIC FINISH!
SO HOT!
I'll let my passion burn and crush you!
SCRAP FINISH!
Come on, let's go.
Yeah...
FUNKY BREAK! CROCODILE!
FULLFULL MATCH BREAK!
We're going to take the country back from Evolt!
ONE SIDE!
FLIPSIDE!
ALL SIDES!
READY, GO!
GENIUS FINISH!
Impossible...
I won't admit defeat!
Look out!
Very good.
The Rider System wasn't built for the sake of idealistic nonsense.
Another Build? What's going on here?
Who is that?
Dad...?
Kamen Rider Build!

Why'd you protect your old man?! He's our enemy!
His father is his greatest enemy!
But even then, Kiryuu Sento managed to get past everything that came his way...
His father is his greatest enemy!
Questioning the justice of Kamen Riders
Right now, you stand no chance against Evolt!
