Pandora's Box, which contains incredible energy,
has finally been opened by the extraterrestrial entity, Evolt.
Kamen Rider Build aka Kiryuu Sento fights against Evolt
in order to rescue Banjou, whose body has been absorbed,
but ends up being possessed instead.
Hey, are you really Sento? Or Evolt?
I'm obviously Sento.
Then make some coffee for me!
Here you go.
Yuck!
You're really Evolt, aren't you?!
Oh well, you got me there.
Here's Episode 37 for you.
EVOLUTION!
ARE YOU READY?
Transform.
EVOL RABBIT!
Phase 3, complete.
He took Sento this time...
Still no good, huh...
That's what I get for snatching up a human's body in a rush.
Now I can't control the power of Pandora's Box.
How dare you?!
The hell are you whining about?!
Give Sento back!
BOTTLE BURN!
CROSS-Z MAGMA!
ARE YOU READY?
Transform!
Sucks to be you.
You won't be able to transform anymore.
What?!
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!
Why...?
Why can't I transform?!
Because you don't have my DNA anymore.
The Ultimate Phase
I've re-absorbed all my genetic material you had.
Simply put, you're just an ordinary human.
Good for you on getting your wish, though.
Then I'll take Sento back!
He's even stronger...
I'm genuinely pissed right now.
Playtime is over!
READY, GO!
EVOLTECH FINISH!
CIAO!
Seriously...?!
I guess I'll just grab Pandora's Box and head back.
It's at Nascita, right?
You're not going anywhere!
Vernage from out of nowhere!
Evolt is coming.
He wants the box.
That's bad! What do we do?!
Come on Ver, we need to run!
Ciao!
Vernage again...
Where are we?
I was told you're some sort of extraterrestrial creature
who brought upon the desolation of Mars.
How about it?
Are you ready to lay it all on the table?
All I want is to regain my full power.
That's the power to control Pandora's Box?
Yeah.
I thought stealing Build's System would complete me again,
but Sento got in the way, and it didn't work out.
So I have to find some way to gather power exceeding Hazard Level 6 with this.
And it's probably not going to be easy.
Then what will you do?
Just gotta be patient.
I've taken quite a liking to Earth, after the last ten years.
You humans are seriously amusing.
No harm in observing you a little longer.
And I intend on continuing our relationship, too.
In that case, I would recommend you retrieve Pandora's Box as soon as possible.
Yessir...
Pay the debt for your crimes...
You have to... rebuild the country...
I'm counting on you... my foolish son...
Sorry we're late, this guy got lost.
That was you.
What do you want?
I can't transform anymore.
I need you to make me into a Rider again.
I can't do that.
Why not?
I don't know the first thing about science.
Weren't you in charge of a lab?
That...
...was just nepotism.
He actually admitted it.
The Rider System compatibility procedure involves an injection of Nebula Gas
along with genetic alteration by Evolt himself.
That's likely why you can't transform.
Seriously...?
Dammit... we're back where we started.
If I can't turn into a Rider, then you're the only one who can back Kazumin up.
Please, fight with us.
I let your woman die.
I know.
But...
That's exactly why...
I don't wanna lose anybody else I care about.
I can't do it.
Using the Rider System to fight requires an emotional drive of a certain intensity.
My drive was to entrust the country to my father.
With him dead now...
I can't find a reason to fight.
Sento
Sento's cell?
Who's this?
It's me.
Y'know, me!
Dammit... where are you guys hiding?
What do you want?
Well, Pandora's Box.
Bring it to me within the hour.
That's not gonna happen!
You sure you don't want to see Sento ever again?
I can erase his personality whenever I want.
I'm the one in control, and don't forget it.
Ciao.
Sento, did you hear that?
Thanks to you...
My whole plan was ruined!
I'm going to destroy everything you care about.
And it starts with your precious little friends!
What are you gonna do?!
Figure something out.
But...
He was always fighting for others.
Never worried about what it'd cost him.
How can we not follow his lead?
"Love and peace..."
When I first heard him say that, I couldn't take him seriously.
But if you think about it...
We've all been fighting for that stuff.
Hey, beardo!
You know your dad's not the only one who can get the country back on track, right?
So you're my babysitters, huh?
Fair enough.
Do a good job, boys.
Let me see it!
Let Sento go!
That's not happening!
What?!
Sento pissed me off.
Which is why he gets to watch me kill you all!
Sick freak...
Then I'll just take Sento back myself!
Transform!
ROBOT JELLY!
What exactly can a Rider that can't transform and some Hokuto leftovers do?
CRUSHED! OOZING! OVERFLOWING!
ROBOT IN GREASE!
This isn't worth my time. Get to work.
You guys...
This is for love and peace.
You'll fight too, right?!
TWIN BREAK!
DISCHARGE BOTTLE! UNCRUSHED!
DISCHARGE CRUSH!
Eat this!
What...?!
Now!
Right!
Rai!
This...
Is the end!
Aw, crap...
Rogue...
Sorry I'm late, potato farmer.
CRACK UP FINISH!
Rai!
Take care of it!
Mistify!
GEAR ENGINE!
FUNKY MATCH! FEVER!
PERFECT!
CRACK UP FINISH!
So, Touto, Hokuto, and Seito's Riders have teamed up...
Very well. I'll entertain you.
COBRA! RIDER SYSTEM!
EVOLUTION!
ARE YOU READY?
Transform.
EVOL COBRA!
I'm not letting you have this country.
Trying to rule it in place of your old man?
I'm well aware that's something I can't do, and that I don't have the right.
I can't lead this nation.
But...
I can lay the foundation...
For the sake of love and peace.
Come on, Grease!
Yeah.
Interesting...
I suppose I'll take this seriously, then.
RABBIT! RIDER SYSTEM!
EVOLUTION!
ARE YOU READY?
EVOL RABBIT!
You think I'd lose to your improvised tag-team?!
How's he so strong...?!
That bottle...
Get out of my way!
EVOLTECH FINISH!
CIAO!
Hey!
You made this bottle from me, right?
When did you...?
But you won't be able to use it.
Even if I can't...
I have to try!
Now this takes me back.
This was how you raised your Hazard Level, back in the day.
But...
The main difference between then and now...
Is that you don't have my DNA anymore.
Not yet...
I'll stand up...
As many times as I have to...
You can do that, but it won't help.
You're just a human.
You could never beat...
What?!
How is this happening...?!
Is it gonna work?
AWAKEN!
GREAT CROSS-Z DRAGON!
ARE YOU READY?
Transform!
WAKE UP CROSS-Z!
GET GREAT DRAGON!
YEAH!
He transformed...
Impossible... I took all the compatible DNA back from you...
Did your body somehow create more?!
Shut the hell up!
But you're still my spawn.
There's no way I could lose to you!
Sento...
I'm going to use the power you gave me to find a way to the future!
BOTTLE BURN!
CROSS-Z MAGMA!
ARE YOU READY?
Lend me your strength!
RED-HOT MUSCLES!
CROSS-Z MAGMA!
HOTHOTHOTHOT!
How? You're even more powerful...
I feel power overflowing...
My soul is on fire!
My magma is surging!
READY, GO!
No one can stop me now!
VOLCANIC FINISH!
So this is the power of Kamen Riders...
Let's set Sento free!
Okay!
CRACK UP FINISH!
READY, GO!
SCRAP FINISH!
VOLCANIC ATTACK!
I'll just put it to use, then!
What was that?!
Let my true power return!
Sento!
Sento...
Hey... what's up with that?
BLACK HOLE! BLACK HOLE! BLACK HOLE!
REVOLUTION!
That's his final form...
Sento?
Sento!
You're...
You okay, Sento?
Sento?
Who is that?
You...
My name is Katsuragi...
Katsuragi Takumi.
Kamen Rider Build!

Why are you helping me, when you have Evolt's DNA?
The Devil's Scientist Returns
From now on, I will lead this country.
The beginning of the end of the world!
It could mean the end of the world!
The beginning of the end of the world!
And now, the final act begins!
