The brilliant physicist and Kamen Rider Build, Kiryuu Sento,
is investigating the murder of scientist Katsuragi Takumi
in order to prove Banjou Ryuuga's innocence.
Their search unearths Katsuragi's involvement in the founding of Faust,
and Sento obtains the data that was being held by Katsuragi's mother.
Hey... "Kiryuu Sento" is what the cafe owner named you right?

What about "Kiryuu" then?
I was on the way to Barber Kiryuu when I found him.

Let's just start Episode 9 already.
My name is Katsuragi Takumi.
Today, I will introduce you to Project Build,
the cornerstone of the ultimate defense application: the Rider System.
The core element is this, the Build Driver.
When it is equipped within certain criteria,
it allows transformation into Kamen Rider Build.
This is Build.
It takes its name from building, naturally, as well as construction.
Depending on the Bottles used in the Driver, Build will have different abilities.
The Bottles are made from the Nebula Gas that the Sky Wall emits,
and depending on how they are combined, they're capable of potent finishing attacks.
READY, GO!
VORTEX FINISH!
YEAH!
As demonstrated.
Additionally, the system allows for a variety of form changes by swapping bottles.
For example, this Wolf Bottle...
And this Smartphone Bottle.
Using these two with the belt...
...would result in this Rider form.
This is just a fraction of what's possible.
Build possesses endless potential!
Thank you for your time.
See you!
I never thought Katsuragi might've been the one to build the belt...
This is totes freaking me out!
It's so bad, I just can't even!
Why are you talking so annoyingly?
A kid from my job taught me some slang.
Am I sick, or what?
Never mind that, you took the belt from Faust, right?
Yeah. Along with the bottles, and the panel.
I thought I could use them to protect Misora,
but I wasn't able to transform.
You need to have an above average Hazard Level, or it won't work.
Hazard Level?
It's how they measure resistance to Nebula Gas.
If administering the gas results in death shortly thereafter,
you would be at Hazard Level 1, like Banjou's girlfriend.
Turning into one of those abnormal Smash monsters rates you at Hazard Level 2.
And beyond Hazard Level 2 are the rare individuals
who maintain human form after being dosed with Nebula Gas.
That's you two, then.
I think Stalk said something like that....
Hazard Level 2.5, 2.6, 2.7...
It just keeps going up!
How utterly fascinating!
According to Katsuragi's data,
if you reach Hazard Level 3, you can use the Build Driver to transform.
Did it say anything else?
I'm certain that the human experimentation with Nebula Gas
was conceived to find candidates for the Rider System.
This is a load of crap...
So they were just using me like a guinea pig?
They killed Kasumi for that?!
That Katsuragi guy didn't give a damn about human lives!
He got what he deserved.
You're right, performing dangerous experiments on humans with the Nebula Gas is a problem.
But from a scientific standpoint, this system of his is an outstanding result...
What the hell are you saying?
This crap cost a ton of people their lives!
If the owner hadn't stolen it, Kamen Rider would be just a murder weapon!
The people around scientists are the ones who weaponize their research!
Don't blame scientists for that!
So you're siding with that devil scientist?
Screw that!
Plus, none of this is gonna help clear my name!
We need to get back on that—
Again?!
Yahoo!
Tired. Want my money. Sleepy.
Sleeping.
So it's a Lock Bottle this time?
Fantastic!
What the hell's wrong with you two?!
It's been ten years since the Martian Pandora's Box caused the Sky Wall Tragedy.
Our country was split in three: Touto, Seito, and Hokuto,
and chaos has ensued.
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 lights, be the lights
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 lights
Send this message and let it ring out!
The Trap of Project Build
It's been a while, Chairman Nanba.
This really is fantastic.
Nanba Juusaburou
Chairman of Nanba Heavy Industries
When I was a boy, I would eagerly wait
for the weekly trips to this bathhouse with my father.
Have you convinced the Prime Minister yet?
Not yet, unfortunately...
Are you aware of how much I've invested in Faust?
The Rider System is a weapon that could reshape the global military status quo.
Or would you prefer that I share what I have with Hokuto or Seito?
No, that would be...
Then you need to convince him as soon as possible.
Understood?
I understand.
Nobody understands what it's like to be a scientist.
What brought that on?
Do you think Katsuragi Takumi was really some kind of devil's scientist?
That's not true at all!
Only ignorant people who'd deny science itself think that.
Kuwata Shingo
Touto Institute of Advanced Matter Researcher
He was a genuine genius!
Kawai Eita
Touto Institute of Advanced Matter Researcher
He's always sympathized with Katsuragi.
But if Katsuragi was still around,
I bet we would've figured out Pandora's Box by now.
The three prime ministers will be visiting tomorrow to inspect Pandora's Box.
I'd like you to put together a report on your findings by tomorrow.
Wait, by tomorrow?
That's impossible.
It should be possible, if you work overnight.
Get to work, now.
Guy's like a cyborg...
Don't just watch, enjoy!
About yesterday...
You cooked up that bottle right then to stop us from fighting, didn't you?
That was a coincidence.
Listen, I been meaning to ask you...
Don't you miss going outside?
Like "I wanna go shopping!" or whatever?
I'd just get caught again...
I know!
Let's go!
No way.
Hey...
Why are we high schoolers? It looks like we're cosplaying.
Shut it. You should've said something sooner!
Hey!
Look, look, look!
I always wanted this outfit!
I'm all set!
Ta-da!
I'm digging in!
Tasty...
You eat a ton.
Yeah!
Alright!
That was fantastic.
Hey, give it a rest.
Alright, let's go there next!
You're still not done?
Just come along!
Come on already!
Miitan?
I think I just heard Miitan's voice!
I did!
Yeah, me too!
Hey, Miitan? Miitan!
Crap... let's go, now!
Now what?!
That was a close one.
You almost became an idol that people could actually meet.
But I had fun!
I've never done anything like it before.
You're joking.
You had to have had a boyfriend or two, right?
Nope. I was asleep for a long time.
Like, seven years.
Seven freaking years?!
I lost consciousness when the Sky Wall Disaster happened,
and spent seven years comatose.
You guys sure love to talk about crazy stuff like it's nothing, huh?
Well... what the hell happened?
I don't remember.
I fainted, and when I woke up, I had this.
It won't come off, no matter what.
I'm able to purify bottles because of it...
Before Sento had finished the transfer device,
just purifying one bottle would put me to sleep for a week.
Well, I still get tired after it...
Ever since this, I've always yearned for a normal life...
Did you go out with Kasumi a lot, Banjou?
Yeah.
She dragged me all over the place.
When I hold this, it feels like she's somehow still here with me...
You really loved her, huh?
That's why I can't forgive Faust for what they did to her.
Same goes for Katsuragi and his experiments.
And then Sento sticks up for that jerk...
Banjou...
Run.
But...
Just get out of here!
Sento, Faust has shown up!
They're in area G3, Banjou is fighting them.
Why would they be there?
Misora?
Hey, what happened?
I didn't mind letting you roam for a bit...
But time's up.
No...
I don't want to go back...
What are you doing?!
Did you think you could beat me unarmed?
Quit raising a ruckus without telling me.
Stalk...
Misora!
Hey!
FIRE SKILL!
BLAZING SLASH!
What were you doing?
Shut up!
I see.
So you were uncharacteristically desperate because of Nanba Heavy Industries.
The Rider System is a weapon that could save Touto.
I'll do whatever it takes to keep it away from the other countries.
And what exactly are you gonna do?
We'll steal Pandora's Box from the lab.
That's enough of a spark to start a war.
Which will light a fire under my father even he can't sit on.
Touto Government Offices
Prime Ministers Tajimi and Midou are here.
Where's Gentoku?
He has some matters to attend to, and will join us as soon as possible.
All-nighters always suck...
What are you doing?!
Knockout gas...?
The time for revolution has come!
Kuwata!
HAWK! GATLING!
BEST MATCH!
ARE YOU READY?
Transform!
HAWKGATLING!
YEAH!
I got lucky, huh...
Where's Sento?
So you called him?
The moment we beat those guys, he hurried back to the lab.
You still haven't made up?
We weren't friends in the first place!
He might even be the one who killed Katsuragi.
You don't really believe that.
You know, Sento saved me.
Faust was forcing me to purify bottles with my power.
After Dad brought me back,
I was so terrified that I didn't want to use it anymore.
That's when Sento told me something...
Thanks to the bottles I've purified, Kamen Rider can be a force for good
and save a lot of people with their powers.
And he thanked me.
Sento even made that dragon, for your sake.
He designed it to be something to guide you.
I have to do more than just prove Banjou's innocence...
I need to help him find his way.
That's what he wants to do to atone for not saving Kasumi.
Atone...?!
He didn't do anything wrong!
That's just how Sento is.
He believes in the power of science.
So instead of blaming Katsuragi Takumi for what he created,
he wants to ensure that it gets used the right way.
Doesn't that sound like him?
I finally get to try this one out!
Let's begin the experiment.
LION! VACUUM!
BEST MATCH!
ARE YOU READY?
Build Up!
THE MANED CYCLONE!
LIONCLEANER!
YEAH!
And now I have the winning formula.
READY, GO!
VORTEX FINISH!
YEAH!
Where is this...?
My mission... is complete.
Mission?
My orders were to lure you away from the lab, so they could take Pandora's Box.
What?!
And I have other comrades, too!
The security lock is disabled.
Begin the operation.
Find Pandora's Box...
Take it.
The wheels are finally in motion.
This is the new intel on Build.
Chairman Nanba.
My job here is done.
Stop!
I'll tell you one last thing...
Katsuragi Takumi...
...is alive!
Kamen Rider Build!

Faust is attacking the lab!
The theft of Pandora's Box
Get back here!
The theft of Pandora's Box
You think you can beat me?
The theft of Pandora's Box
Are you Katsuragi Takumi?
The Devil's Scientist is Alive...?
I'm going to retrieve all of the bottles.
The Devil's Scientist is Alive...?
Technology of Destruction
I can't afford to lose!
