According to this book, in September of 2018...
The ordinary high schooler, Tokiwa Sougo,
has a future wherein he becomes the overlord and ruler of time, Oma Zi-O.
In order to prevent this, Geiz and Tsukuyomi arrive from the future.
However, Tokiwa Sougo chooses to obtain the power of Kamen Rider Zi-O
and defeats Another Build.
Then, Zi-O steals the power of Kamen Rider Build,
taking his first step into becoming the overlord.
Oh! Perhaps I've read too far ahead.
Let's do this, Oma Zi-O!
I've got a bad feeling about this.
The legacy of the Heisei Kamen Riders has carried on throughout the era.
And now they pass their power on to the next generation!
Rejoice, for the birth of a new king!
Gonna grab it in a second, so are you ready?
It's a brand new history, can you feel it feel it?
Making our bonds the guiding light
Now it's time to shout it out, shout it out!
And move forward through the present
No matter how often you feel lost
Make sure you knock on future's door
Once you've got your sights on what's beyond
Just jump in and believe in yourself!
Now Over Quartzer!
We'll slip through the raindrops of time, together
You Over Quartzer!
Go beyond the future!
The lessons of the past can't be clouded by lies
Now feel the Nexus future
Now Over Quartzer!
A brighter world is coming
Take me there!
Best Match
You haven't done anything wrong yet, in this time.
But this is for the future's sake.
FINISH TIME!
GHOST!
You have to die.
OMEGA TIME BURST!
Tsukuyomi!
Zi-O, you have to run!
Okay, but...
"Bike?"
I can do this!
I don't think so!
Wait!
What?!
Okay...
Where'd he go?
What are you trying to pull?!
Why did you stop me?!
I don't really know myself.
Well, don't stop me next time.
I have to beat him.
Zi-O got his power after all...
Well, no matter.
Everything's going as expected, so far.
What a mess...
It is an honor to encounter you again, my overlord.
Buddy, just who are you?
A friend of Tsukuyomi and Geiz?
My name is Woz.
Woz
Unlike Tsukuyomi and Geiz, I am on your side.
Woz
According to this book,
The Twilight Chronicle
you will rise to become the ruler of time, by walking a path of conquest.
However...
There are Time Jackers who would impede your ascension,
BUILD!
in an attempt to groom others to become king.
So everybody's trying to change history?
Indeed.
I am the only one who seeks to protect history as it has been.
I will spare no effort so that you may safely travel your path to becoming overlord.
Huh?
He's gone again.
Help!
No!
The monster from before...
Why? Wasn't he beaten?
Another Riders...
I guess the Time Jackers are here in this era, too.
Leave him. We need to focus on our mission.
But...
Fine...
GEIZ!
Transform!
RIDER TIME!
KAMEN RIDER GEIZ!
9 To 5 Workshop
There you are again!
I forgot to mention something.
About Another Build, who you defeated before...
Another Build?
Pardon me.
I suppose I should call him Kamen Rider Build?
Kamen Rider Build?
This is Kamen Rider Build.
Kiryuu Sento.
No... that thing looked like Build, but it wasn't him.
The Time Jackers have altered history.
Right now, that thing is Build.
Then what happened to Sento?
Who knows?
Incidentally...
Even though you are the overlord, you cannot defeat Build.
Although Geiz has engaged him in battle, even as we speak.
What?
Geiz!
What's going on? He's stronger than before!
EDGE OF TIME!
SWORD!
You okay?
Is this guy really Oma Zi-O...?
The one we've fought?
FINISH TIME!
KICK
TIME BREAK!
RIDER KICK
What?!
Oh, it didn't work.
Maybe the real Build could do it...
Sorry! I've got somewhere to go!
Where are you going?!
Huh?
Lynks are the best!
That was so exciting, my dear Banjou!
Their first live at the Budokan!
Oh man, I feel like I've cried 9.8 newtons worth.
I have no idea what you mean, my dear Takumi!
Anyway, this is only the beginning of the legend of Lynks!
And tonight...
We're gonna chow down yakiniku!
Sento?
Whoa, who the heck?
Never seen this guy before.
This is a Lynks Fan Cafe, dude.
LYNKS
I'm Tokiwa Sougo!
Remember, the pushy guy from the future!
I need Build and Cross-Z's help!
Build...?
Cross-Z?
Did you forget?
FINISH TIME!
TIME BURST!
Watches? Why do you have those?
Creepy!
What the hell is this crap?
You... the dude from the future.
Yeah! Sougo! Did you remember?
CROSS-Z!
BUILD!
What the heck are these...?
I remember now.
What?
You can take this back.
Send my past self my regards.
Yours, too.
Huh?
I don't get it.
Regards to his past self...?
I get it!
He won't stay down...
Could it be?
Zi-O!
Where'd you go?
To see Kamen Rider Build!
Build?!
I think we must've gone and fought in the past.
Along with Build.
So if we go to 2017...
We can actually beat Another Build?
TIME MAZINE!
Space-Time Transport System...
Activate!
Swimmer! Archer!
Best match!
What is that thing?
It sure don't look like a Smash.
Me Build.
You... Cross-Z!
Best match!
That is super freaky!
I feel oddly jealous.
RABBIT! TANK!
BEST MATCH!
ARE YOU READY?
Transform!
THE FULLMETAL MOONSAULT!
WAKE UP BURNING!
GET CROSS-Z DRAGON!
YEAH!
Alright!
You stupid—
My power's fading...
What's going on?!
I'm not sure.
But we need to stop him!
Banjou!
It's like he really is Build!
Swimmer! Archer!
Best match!
TIME MAZINE!
Sento!
You're that guy from the other day!
Hey, it's future boy—
Zi-O.
Would you stay out of the way?
We're just trying to give rise to a new king.
A new king?
You're a Time Jacker?
You know your stuff!
Heure
My name is Heure.
And that guy over there...
In the original timeline, he had an accident
which ended his athletic career.
His time was meant to stop on this moment.
I'm the one who started moving the clock for him again!
No, you didn't.
We can stop the hands of a clock, we can turn them back...
But that's just not how life works.
You're the only one who can choose what future you'll take.
Time that hasn't been put into motion by yourself isn't really moving.
What an interesting statement.
Even in youth, you're impressive, Zi-O.
Why don't you show me what kind of future you'll choose?
Let's go.
SPACE-TIME DRIVER!
ZI-O!
GEIZ!
Transform!
RIDER TIME!
KAMEN RIDER ZI-O!
KAMEN RIDER GEIZ!
Sento! Ryuuga!
Looks like our power is vanishing.
It's up to you, now.
Build... is gone.
Sento...
GHOST!
ARMOR TIME!
EYES OPEN! GHOST!
Stop gawking!
I see!
By using that watch, you will inherit Build's power.
How did you get here? We're in 2017!
According to this book, victory will include a fair deal of responsibility.
Are you prepared for that, sire?
You bet I am!
BUILD!
RIDER TIME!
KAMEN RIDER ZI-O!
ARMOR TIME!
BEST MATCH! BUILD!
Rejoice!
He is heir to the power of all Riders.
The ruler of time, traveling beyond time and space to reign over past and future...
His name is Kamen Rider Zi-O: Build Armor!
And in this moment, he has first received the power of another Rider!
I've got the winning formula!
Formula!
TIME Z-AXE!
YOU BOW TO ME!
I can do this!
I just need to shake, right!
"Learned in first grade" "Part I don't understand" "Some difficult numbers" "Nothing but numbers" "Alphabet" "Lucky number x Lucky number"
That don't seem right.
This is terrible.
FINISH TIME!
BUILD!
FINISH TIME!
VORTEX TIME BREAK!
BRINK SHOT!
What just happened?
Hey, why did you have the Build Watch?
Sento and Ryuuga gave it to me.
But they wouldn't have it in the first place.
Hey!
Here, can you take these for me, Sento?
Sento?
My name is Katsuragi Takumi.
What is this device?
The way it's constructed...
How incredibly fascinating!
Hey, Takumi!
Hey, what's going on here?!
How should I know?
But I'm sure that's going to turn into the Build Watch, in the future.
Even if history changes, Sento will choose to become Build,
and Ryuuga will choose to become Cross-Z.
That's what I think.
Hey!
What's wrong?
Back then...
I wouldn't have expected Zi-O to protect us.
You okay?
Is this Zi-O really going to be the Oma Zi-O we know?
Even when we beat Another Build,
Kamen Rider Build was still missing from history.
And Tokiwa Sougo obtained the Build Watch.
History is headed in the flow that gives rise to Oma Zi-O.
Where are you going?
There's only one thing for us to do.
Geiz!
Sougo! Breakfast's ready!
Good morning...
'Morning.
Oh, remember the vacant room on the second floor?
Rooms Available - Owner
Yeah.
Well, it's rented out now.
Come here a sec.
And so, since we'll all be living together, let's introduce ourselves!
I'm Tsukuyomi. It's nice to meet you.
Geiz.
This seems sudden.
Whether or not you're Oma Zi-O is something we'll watch for up close.
'kay thanks...
I'm still itching to get rid of you.
Well? Think you'll get along?
Yeah. We can do this just fine.
Well, that's good.
And thus, Zi-O obtained the power of Build.
His path of conquest had only begun.
However, his meeting with another legend was already at hand...
Next time, on Kamen Rider Zi-O...
A game that can't be beat?
I'm Ora, a Time Jacker.
What do you want with the pediatrician?
The legendary Ex-Aid appears!
He's...
The legendary Ex-Aid appears!
The legendary gamer, M...
Doctor Gamer
Transformation Plus!
