War between Touto and Hokuto broke out over the Pandora Box...
An artifact containing a tremendous source of energy.
Kamen Rider Build, otherwise known as Kiryu Sento,
chose to fight to protect Touto, facing many deadly opponents such as Hokuto's Kamen Rider Grease and the Trio.
In the end, the key to this war would be the Sclash Driver.
Um... who are you?
- Utsumi.
Oh, you're that cyborg—
No!
That's just a nickname you called me as.
But I thought you were...
It's because you're a cyborg!
- No!
It'll all be explained in Episode 19.
Utsumi...
I suppose you're wondering... why I'm still alive after you killed me.
It was Stalk.
He saved me.
I didn't have any other choice back then.
I'll be your point of contact for Nanba Heavy Industries from now on.
Very well.
Then tell me...
How is Faust still operating if it was shut down for good?
The Hard Smash could not have been created without Faust's knowledge and resources.
You must have created Faust in Hokuto, haven't you?
I'm afraid I am unable to answer that question.
STOP MESSING AROUND!
Faust was founded by Katsuragi and I!
I won't let you have your way with this.
Please leave.
What did you say?
Kamen Rider Grease...
His strength is the real deal.
But how is he stronger with the same belt?
That just goes to show how much more experienced he is.
Then we're just gonna have to go all out on him.
- That's not an option.
In order to draw out one's fighting instincts to the max...
The Sclash Driver induces the production of excess adrenaline.
It puts a comparable amount of stress on the body.
But...
Do we have any other choice?
I found a hidden command in Katsuragi's research data.
It's most likely an upgrade item for the Build Driver.
I just need to find the right keyword to unlock it and—
- We don't have time for that.
I'll make sure to beat him up for good next time.
We aren't fighting this war in order to defeat our opponents.
We're doing it to protect Touto.
Either way, we're still going to be fighting.
It has been 10 years since the Skywall Incident caused by the Pandora Box found on Mars.
Our country was split into three - Touto, Seito, Hokuto,
and descended into chaos.
Walking endlessly through the night
kono mama aruki tsudzuketeru
Following the footprints you've left
konnya mo massugu hitori no ashiato tadotte
And if the journey takes an eternity
hateshinai dakedo kimi dake wa
I know you'll be waiting, with that neverending smile
doko ka de matteru egao tayasazu ni
There you will
Be The One, Be The One
All right!
Who won't ever give up Earth's tomorrow!
ashita no chikyuu wo nagedasenai kara
Be The Light, Be The Light
All right!
You'll become stronger, so that love always prevails!
tsuyoku nareru yo ai wa makenai
Treasure and embrace the things you want to save
nanika wo tasuke sukutte dakishime
As you feel my beating heart be passed on
kokoro ni furete todoku yo tsutaware
Be The One, Be The Light
Send that message through as it reverberates!
Message okuru yo hibiku yo
We're at a stalemate here.
Yeah.
Mii-tan...
She's cute.
Right?
The Forbidden Item
Episode 19
But...
Why is she with Build...
Maybe she's Build's girlfriend!
Like hell she is!
Mii-tan is everyone's idol!
- Sorry... - We're back!
What's going on?
Nothing.
Bread!
Yeah, bread!
Eat up, eat up!
Why are we using a place like Barber Kiryu as our hideout?
Don't worry, this is now part of Hokuto's occupied territory.
Stalk recommended this place, right?
R-Right!
So, did you find Build?
Nope, we couldn't find a thing.
Maybe he's hiding somewhere underground?
Mr. Utsumi's alive?!
It's likely that he's the one who built the Sclash Driver using your research data.
He was a talented scientist before he became my secretary.
However, if Hokuto has the same weapon on their side...
We're going to need something that will surpass it.
That's why I wanted to talk to you today.
I'm trying to find a keyword to access the hidden section of the research data.
Now that you mention it...
Katsuragi once mentioned he created some kind of forbidden item.
Forbidden item?
How about you throw out another one?
Got it.
L-Look!
Why are you guys here?!
We wanted to pay our respects to the heart of the city.
This is perfect timing.
I've got a question for you.
What's your relation to Mii-tan?!
Mii-tan came to help you during that fight we had earlier, right?!
She's, um...
Someone else.
Someone else?
She gets mistaken for her a lot.
(Pirate) KAIZOKU!
Seriously?
(Train) DENSYA!
BEST MATCH!
Geez, I got all worked up for nothing!
DRAGON JELLY!
ARE YOU READY?
Okay, one, two...
Henshin!
Mii-tan! Mii-tan! Mii-tan!
DRAGON IN CROSS-Z CHARGE!
THE PUNCTUAL SWASHBUCKLER!
BURRRAAH!
KAIZOKURESSYA!
YEAHHH!
I'm feeling better now.
I'll crush you with my burning soulfire!
REGULAR TRAIN! EXPRESS TRAIN!
RAPID TRAIN! PIRATE TRAIN!
FULL STEAM AHEAD!
I can feel power building up inside me!
RABBITTANK SPARKLING!
Build Up!
RABBITTANK SPARKLING!
YEAH YEAHHH!
As expected of Build.
You have all kinds of tricks up your sleeve.
It's my turn now!
Passion!
Overheat! Euphoria!
SINGLE!
SINGLE FINISH!
Here we go!
Our attacks aren't working!
What the hell are you guys doing?
I'll be your opponent.
READY GO!
Bring it on!
LET'S BREAK!
You guys sure are going at it.
Why'd you have to get in the way...
What's going on, Mr. Stalk?
Why?
I thought that this might be a good time to get a reading on everyone's Hazard Levels.
Your Hazard Level is...
3.7!
CASTLE
3.6!
OWL
3.7!
STAG
4.2!
GREASE
3.9!
BUILD
4.0!
CROSS-Z
Right now, this is how strong you are.
Sento, Banjo has surpassed you.
You're gonna have a tough time if you wanna stop him now.
Let's break up for today.
Return to Hokuto.
What are you saying?
If you want to go back, do it on your own.
My orders are from the Prime Minister herself.
(Eraser) KESHI GUM!
DISCHARGE BOTTLE!
UNCRUSHABLE!
DISCHARGE CRUSH!
- Hey wait! - Don't leave me!
Hey...
Hey, you okay?
I'm fine.
Hokuto
I felt that you might be having trouble with retrieving the Pandora Box and the Bottles, so I had you return.
Don't screw with me.
I'm stronger than Build or Cross-Z.
My Hazard Level proves that too.
For now.
Banjo Ryuga is becoming stronger faster than anyone.
It's only a matter of time until he surpasses you.
Then you can just do something to me.
Unfortunately, I cannot speed up your level growth.
The Trio are the only ones I'd be able to do anything on.
If this is used on them, their Hazard Levels will shoot up.
Probably till they're as strong as you.
However, in exchange, their bodies will be destroyed if they're defeated.
So you're saying they'll die?
That's right.
But they will obey if you order them to do it.
So...
There's no way I'd make them do that.
You'll be in trouble if Cross-Z gets stronger than you.
If you can't retrieve those Bottles...
Then you're out.
I'll snatch the Bottles before that happens.
Come on out now.
Now, you guys heard what your leader said, but...
What will you do?
After speaking with the government, we've decided to disperse the Bottles.
Four in the Government Residence...
Two in the Research Institute...
Two in the Archaeology Museum...
And two in the Clean Center.
We'll hold the rest.
But it's dangerous if we leave them here.
That's right.
We should split them up between us too.
Is everyone here?
I've found some info on Grease and the others.
Grease's real name is Sawatari Kazumi.
Sawatari owns a large tract of farmland...
From residence certificate: Sawatari Kazumi 29 years old Born July 17 Parents deceased Only son From residents in the neighborhood: Large landowner, 100ha Employees 4-3 people Tubers, cabbages From Underground Newspaper - Reporter: Soil contamination, crops failed 1 employee made off with money? North Credit Union 4 million in debt?
And those three worked under him.
But...
When the Skywall Incident happened, the soil composition changed.
Due to that, Sawatari's farm fell into a devastating condition.
The soil's gone bad...
The Boss threw away his life savings...
To look after us and our families.
We worked as hard as we could...
But one day, we even ran out of food to eat...
So you guys decided to apply to undergo the experiments to become weapons, huh?
We're thankful to you... for using us as well.
Don't worry about it.
We can't let the Boss hog all the glory.
With this...
We can be of use to him...
So Grease willingly underwent experimentation...
In order to earn money for his friends' living expenses.
They're victims of war too...
But that doesn't change the fact that they wrecked the streets of Touto.
There's no room for sympathy.
I'll take down each and every one of them.
I won't let you use this anymore.
Why?
Without that—
- You should've noticed how much your body has changed!
If your body keeps taking more damage...
- Are you jealous of how strong I am?
What did you say?
Don't order me around when you're weaker than me.
I'll knock Hokuto down.
That's all there is to it.
Will he be okay?
There's no cure for idiocy.
It's so lonely around here now, right?
Because they'll get involved in the war if they go out.
It's not right for kids to not to be able to play in the parks.
He's probably thinking the same thing.
We haven't seen him smiling in a while.
I can't blame him, though.
He thinks that it's his fault everything's like this.
That's why...
I want to end this war as soon as possible.
So you're doing this for Sento...
He's already done so much for me.
You know, if I never met him...
I probably wouldn't have trusted others as much.
This time...
It's my turn to become his strength.
You've grown, Banjo.
Shut up.
Upgrade Bottle
It's no use...
I can't find the right keyword.
Grease just showed up at the Touto Clean Center.
Head there immediately.
How did the Bottles' hidden location get leaked?
TOUTO CLEAN CENTER - Area C8 Branch
These two Bottles are mine now.
Seriously...
Where on Earth did those those three idiots go...
Wait!
How did you find those Bottles?!
I'll tell you if you beat me.
SCLASH DRIVER!
ROBOT JELLY!
Henshin.
CRUSH!
FLUX!
OVERFLUX!
ROBOT IN GREASE!
BURRRAAH!
(Hedgehog) HARINEZUMI!
(Fire Engine) SYOUBOUSYA!
BEST MATCH!
ARE YOU READY?
Henshin!
FIREHEDGEHOG!
YEAHHH!
TWIN BREAKER!
I'll be using these.
PHOENIX!
(Cleaner) SOUJIKI!
Build Up!
ARE YOU READY?
As expected of Build.
SINGLE!
You're making this fun.
TWIN!
TWIN FINISH!
Build Up!
RABBITTANK SPARKLING!
YEAH YEAHHH!
Not bad.
Looks like strength can't be measured by just Hazard Levels...
Boss!
Sorry to keep you waiting!
You're late.
Where'd you guys go?
Well, just leave things to us.
Don't get too surprised now.
Don't tell me you guys...
As of today, we're no longer Hard Smash...
We're Hazard Smash!
Hazard Smash?!
Hey!
Do you have any idea what you've done?!
We'll talk later.
Let's take those Bottles!
What's going on?!
We're not the same as before!
Let's go!
You guys are too damn reckless...
DRAGON JELLY!
You idiots...
Henshin!
DRAGON IN CROSS-Z CHARGE!
BURRRAAH!
I'm super irritated right now.
I can't believe you used it again...
You idiot!
Shut up!
Come at me.
I want to become stronger!
Stronger! Stronger!
Shut up!
Stronger!
This is bad!
Banjo!
Hey, don't look away!
The Bottles dropped, they dropped!
Hey, hand that over!
All right, let's go.
But we could snatch more Bott—
It's fine.
HELICOPTER!
DISCHARGE BOTTLE!
UNCRUSHABLE!
DISCHARGE CRUSH!
- H-hey, wait! - Wait!
- We're so high up! - And off we go!
Hey, come back!
- Those punks... - Don't go!
Your body is at its limit.
Shut up!
(Hawk) TAKA!
CHARGE BOTTLE! UNCRUSHABLE!
CHARGE CRUSH!
I knew it was going to turn out like this.
Where...
Where did they go?!
Where?!
I'll tear you to shreds!
He's falling down!
Banjo! Are you okay?!
What was that just now?
This is...
His wounds... are healing...
W-What the?!
A ghost?
He's rampaging as I expected.
I'll tell you how to stop his power.
The forbidden item that Katsuragi made...
The Hazard Trigger.
Kamen Rider Build!

PRE
VIEW
If you continue using it...
The weapon that destroys everything...
There's a possibility you'll lose your sense of self.
Kamen Rider Build is a work of fiction.
Will it destroy Build?
I will stop the war.
Doing things which cause tears like that...
I will stop you...
