The brilliant physicist Kiryuu Sento
fights to protect Touto as Kamen Rider Build.
He sets off to prove Banjou Ryuuga's innocence
by trying to solve the mystery of Katsuragi Takumi's murder.
Why are you being so calm about recapping the story?!
You might've been the one who killed Katsuragi Takumi!
Hey, don't drag personal circumstances into the recap.
Did you kill Katsuragi and frame me for it?!
Well, they're supposed to find out by watching the episode!
That said, what'll happen on Episode 7?!
Banjou... what's wrong?
He's been like that for a while now.
He's like a stalker.
Stalker?!
You killed Katsuragi Takumi, didn't you?
That's the 328th time you've said that.
"You killed him" Counter
How many times do I need to say it?
Where's the proof that I did it?
It has to be you!
Tatsuya said as much!
When you went to your job with the new drug, on September 9th,
I was the one who I drove you there...
It was Katsuragi Takumi's place.
Hang on.
September 5th, a year ago...
That's when Banjou showed up at the room of that scientist, Katsuragi Takumi, right?
- Yeah. - But...
Katsuragi Takumi was already dead, at that time...
Around what time was that?
Ten in the morning.
And...
He dropped by one hour earlier, at 9AM.
Which means he was there first, so he had to have killed Katsuragi!
Don't jump to conclusions!
He might've been dead already when I showed up.
Besides, I can't remember—
This again?
That amnesia sure is convenient.
I got locked up and called a murderer because of you!
You screwed my whole life up...!
Stop blowing things up when I'm trying to talk, here!
A panda, huh?!
How cute!
Totally different from a certain obnoxious ape.
Who are you calling an ape?!
Tired. Sleepy.
And you're still at it.
Admit you're guilty and turn yourself in.
I will when you have some proof.
For the record...
No one thinks I did it other than you!
What was Kiryuu Sento like...?
Or rather, the suspect, Satou Tarou?
He was always raving about being a brilliant physicist like some kind of nut,
so I kinda saw this coming...
Hey, don't say that!
See, look! You killed Katsuragi!
There it is... the 329th time.
"You killed him" Counter
Somebody help me...
"You killed him" Counter
Go, owner!
"You killed him" Counter
Sounds to me like you just need to look into Katsuragi.
That's it!
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!
Did Katsuragi stop working here before he was killed?
The Devil's Scientist
Two years prior, actually.
Why did he leave?
He broke a taboo.
Human experimentation.
Mr. Himuro...
Administering Nebula Gas could unlock the next stage of human evolution!
Those experiments could give birth to dangerous, bizarre abominations...
You'd never get official approval.
Please!
It's for the future of science!
Naturally, the government did not approve.
But Katsuragi wouldn't let go.
He began performing experiments in private.
Stop...
Stop!
He was stopped before the gas was administered, so there were no casualties...
But Katsuragi was let go from the lab on that day.
And that's why he's known as the devil's scientist...
What are you looking at?
Katsuragi's research data.
But something's weird...
The experiment log is updated daily,
but the updates end a month before he was fired.
And there's no references to human experimentation at all.
Maybe he hid it somewhere...?
Where would he hide it?
The final post is totally meaningless.
And that strikes me as odd...
In the end goodbye all.
If it was me...
I would use an anagram.
Anagram?
Rearranging the letters of something to get a different word.
If you use Roman letters to write out the last entry, and rearrange them,
you get "I've left everything with my mother."
So his mother has that secret info?
It might be related to human experimentation,
and it could be the key to this year-old mystery.
I think we should meet with Katsuragi's mother.
Does she live in Touto?
No.
She moved away and now lives in Hokuto.
I want to go as soon as possible, any ideas?
I don't think you can take a smuggling ship there.
Hokuto's well known for its strict control of immigration.
The only option might be...
The Sky Road.
Sky Road?
There's a couple of openings in the Sky Wall.
Some of those lead to Hokuto...
There are some the government doesn't know about.
That's the Sky Road.
But you have to pay the brokers a pretty sum to get them to take you through...
Money, huh?
You want me to pay?
Me, who still works part time jobs, at my age?
I can't even serve coffee properly...
I can't either!
I'm barely making enough to pay for my own stuff.
And there's Fumie's wedding next month...!
Hell no.
Oh, fine...
Hi!
It's your idol, Miitan!
I have a very important request for all of you today!
Okay. I'll guide you through the Sky Road.
Misora's kinda awesome...
Yeah.
Wait, why are you a clown?
What did you want to talk about?
Kiryuu Sento has headed for Hokuto.
What did you say...?
So, what now?
If the Hokuto government gets a hold of him, this will all be for nothing.
Your plan to make Kamen Riders for military use will go to waste.
We need to stop him from going north, at all costs.
Let's move, now.
Have fun on your own there.
I don't take orders.
BAT
Vaporize.
MIST MATCH
BAT
FIRE!
Wha—?!
Shut up, and come along.
Yeah, okay...
That's it.
That's the Sky Road...
Hey, what the hell? You don't get to pass through here.
We're sorry.
We have money, so please...
Refugees from Hokuto?
Yeah, no. Not enough.
Go back to Hokuto.
Please!
We can pay you the rest once we get to Touto!
We want to be free!
Please!
Honey! Honey...!
I can explain...!
Please don't...!
Night Rogue...
I know you're out there, Build.
Show yourself.
Or else...
If you don't, everyone here...
...will die.
RABBITTANK!
YEAH!
Let those people go!
Hey!
Hurry and go!
ICE STEAM!
ELECTRIC STEAM!
You are not going to Hokuto.
And neither are you.
Banjou, get on!
Stalk!
Yeah, yeah...
RIFLE MODE!
FULL BOTTLE!
STEAM ATTACK!
Get a move on! C'mon!
I-it's dark in here! Whoa!
Bastard...
Don't expect any thanks.
So this is Hokuto...
Lots of soldiers around.
When the Sky Wall Disaster happened, all of society became unstable.
The changes in soil composition made Hokuto's existing produce crops unsustainable,
and the economy has been reeling ever since.
She should be around here...
Alright, that's it for today.
Make sure to do your homework.
Okay.
Thank you!
Hey, a clown!
You're right! Awesome!
H-hey!
Hey, cut it out! Stop it!
I said stop...!
Don't take that!
Banjou Ryuuga...
Are you Mrs. Katsuragi?
There's a long story behind this...
Leave.
Get out of here, right now!
I told you not to come.
Hey, old dudes!
Do you know Takumi?
Kinda...
We're not old.
We're like, young dudes.
Who are you kids?
We're learning how to read and write from our teacher.
We don't have enough money to go to school.
I see...
Is your teacher nice?
Yep.
When I get older, I want to teach people for free too.
And then I wanna be a scientist, like Takumi.
Have you met him before?
No.
But our teacher talks about him all the time.
She says she's so proud of her son, because he's really smart.
And she always makes his favorite rolled omelette every day.
So that he can eat it whenever he comes home.
That's weird, right?
He's already dead...
Why have you come here?
You boys go home.
Okay.
Bye bye!
How much more do you want me to suffer?
It's not true. He didn't do it.
This isn't the man who killed your son.
It might have been me...
What do you mean?
Yo, it's been a while!
Well, not really.
Stalk!
Why are you here?!
I heard you two were sniffing around Katsuragi Takumi...
So I figured...
DEVIL STEAM!
We could have a little fun!
Takehiko!
How'd he turn into a Smash?!
With this bad boy, I can administer Nebula Gas without all that equipment.
Pretty sweet invention, right?
It doesn't deserve to be called an invention!
NINJA! COMIC!
BEST MATCH!
ARE YOU READY!
Transform!
THE STEALTH ENTERTAINER!

CONCEALMENT SKILL!
BOOM!

It's gonna be okay.
FIRE SKILL!
BLAZING SLASH!
Alright!
Banjou! Take the essence!
Takehiko!
Takehiko...
Teacher...
It hurts...
It hurts?
It's hard to breathe...
He's just a kid, so the damage is worse than usual.
Hang in there!
Am I gonna die?
What are you talking about?
You wanna be like your teacher when you grow up, right?
Yeah...
When you get there, how about you teach me too?
It's a promise.
Okay...
PANDA!
GATLING!
ARE YOU READY?
Nice attack.
RIFLE MODE!
That's...!
FULL BOTTLE!
How about this one?
STEAM ATTACK!
A guided rocket?!
Sento!
CROSS FLAME!

That's hot!
Use it!
PANDA! ROCKET!

BLASTING OFF IN MONOCHROME!
ROCKETPANDA!
YEAH!
Catch!
I've got the winning formula.
READY, GO!
VORTEX FINISH!
YEAH!
You've gotten stronger again.
Since that was fun, I'll let you in on a little secret...
About good old Katsuragi Takumi.
He's actually the creator of the Smashes.
Katsuragi Takumi is the man who founded Faust!
What...?
Now...
What's your next move?
Is that true...?
Did Katsuragi really create Faust?
Takumi did what...?
Kamen Rider Build!

Where's that data?
As long as we have that,
The Secret Faust Data
the military applications of the Rider System will evolve even further.
The Secret Faust Data
It might be something you regret finding out.
The Secret Faust Data
Why is Sento crying...?
The thing I fear the most is not knowing about who I am.
