Tokiwa Sougo...
There are three paths open before you.
Will you choose Tsukuyomi, or yourself?
Or maybe...
Will you choose the path of Oma Zi-O?
The path of Oma Zi-O...?
You are free to choose whichever path...
But hurry, you don't have long to decide.
What is this...?
Fulfill your purpose...
Your driving purpose, as a natural born king.
As it is written here, Tokiwa Sougo...
He embarks on a path which leads him to become the overlord of time, Oma Zi-O.
Now, that future is on the precipice of becoming reality.
Only three pages remain... before the end of the world.
Twilight Chronicle
The legacy of the Heisei Kamen Riders has carried on throughout the era.
As their powers are assembled, the curtain rises on the final battle.
Now blaze a path to become the one true 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!
Vanishing Watch
Well...?
Vanishing Watch
We can't even reach him...
I want to believe that my overlord can persevere regardless, but...
C'mon everyone, food's ready!
Now, eat up!
You were looking for Sougo all night, you must be hungry!
I'm so sorry, you must be the most worried of us all...
Me, worry? Nah!
Anyway, there's this strange wall out there now.
The country has been divided.
Maybe Sougo was on the other side of that wall,
and now he's just stuck out there.
Wait, why all the tofu?
Well...
So in the old days, the imperial court used to call tofu "okabe."
Which also means "walls." So eat some up, and then tear some down!
Sougo!
I knew it...
The Build Watch!
I think that wall has something to do with Kamen Rider Build.
I saw it, when I met him in 2017.
According to this book, that was the Sky Wall.
A wall that existed in Build's timeline.
BEST MATCH!
But that timeline should no longer exist, thanks to my overlord...
We need to talk.
Sougo...!
Zi-O!
What happened?
Swartz made contact with you, I presume?
He was after you all along!
I know.
I should've realized it sooner.
He's been watching me for a long time.
Be careful with your next move.
I can't just wait around!
I need you to come with me, Tsukuyomi.
No...
Alpina.
That's your real name, isn't it?
How do you know that?
Miharu is dead.
Tsukuyomi's...
Alpina's future...
I don't know if I can fulfill his last wishes...
Get out of here, now!
Woz, what are you doing here?!
May I ask the same of you, Geiz?
I'm killing time until Zi-O gets back!
Well then, may I join you?
PROJECTING FINALLY TIME!
GINGA FINALLY! FINALLY!
FURY!
There you are.
I want you to take me back there.
Back where?
Back to where I came from...
To the other timeline...
But that timeline isn't completely separate, is it?
There's something connecting her timeline to ours, something significant.
It's a possibility.
Swartz told me...
He said I had to choose... Between this timeline, or Tsukuyomi's.
Okay, but you're gonna see some stuff you'd rather not see.
And we can't turn a blind eye to it.
I need to know the truth if I'm going to make a decision.
Suit yourselves.
Two things to keep in mind.
One, there's no guarantee you'll get anything out of this.
And two...
A banana doesn't count as a snack on a trip.
FINALLY BEYOND THE TIME!
SINGLE BLOW TIME BURST!
Density Shift?!
That means...!
The enemies of Kamen Rider Drive...!
SPEED TIME!
FINALLY TIME!
REVIVE REVIVE REVIVE!
GINGA PLANETARY!
REVIVE TYPHOON!
TYPHOON!
You can fight all you want, it won't get you anywhere.
Swartz!
What?!
The end of the world has already begun.
Everything rests on Tokiwa Sougo's decision.
Wait...!
The end of the world...?
What the hell did he say to Zi-O?!
More intruders!
Even as a kid you had a tough streak, Tsukuyomi.
Alpina, please just listen...
Who are you?
I'm you, 11 years from now.
But I lost my memory.
I'm not trying to intervene, I just want to ask some questions.
What is happening to this world?
This world...?
I'll tell you.
Swartz!
This world is about to disappear.
But I'm going to save it.
Save it...? How will you do that?
By destroying the other worlds... all of them.
It's happening again...
Look!
I will defeat the Kamen Riders.
Another Dark Rider?!
Do not associate me with them.
I am the Grim Reaper, and I am far beyond any Kamen Rider.
There are multiple worlds that exist.
Why should this one have to end?!
If that's how it has to be, then I'll just destroy the other worlds.
If I do that, then this one will be allowed to survive.
And you don't care if everyone else dies?
You know you won't get away with that!
How sanctimonious for a woman holding a gun to a child!
What was that?
He must be using his power to project illusions.
One more question.
When you say you'll destroy the other worlds, how will you do it?
That's easy, I'll just combine them together.
Each reality has its own Kamen Rider.
If you combine them into a single Rider, the worlds will follow suit.
Then I just need to destroy that world.
So that's why you made Sougo...!
I don't care what you have to say. Let's go, Alpina.
So what happens if your sister is more powerful than you?
Alpina...?
You want to save this world, right?
So you'll help your sister if her power is stronger, right?
No!
I would never!
If that ever happened, I'd rip away her memories and banish her!
Why?
Only the strongest can be king!
And I will be the king!
TUNE! CHASER COBRA!
Humans, did you think you could outrun the Reaper?
You appear rather human, yourself.
Human?
I am a Roidmude, a mechanical lifeform created by Krim Steinbelt.
Krim...?
One of Drive's people.
Then you know him!
Shijima Gou, Kamen Rider Mach.
I know of no such person.
There are no Kamen Riders in my world!
You contradicted yourself.
What contradiction?
Why are you attacking us?!
Because you are Kamen Riders!
If your world has no Kamen Riders, how can they be your enemy?!
That is...
You know the truth, even if history has been altered!
About the Kamen Riders... and Shijima Gou!
Shijima Gou...
Chase!
The distortion of space-time goes unabated.
Let's go.
Alpina, I won't let you stand in my way.
Tsukuyomi, don't.
He's going to destroy the world...
If we get rid of him now, we save countless other people.
You truly are my dear little sister.
But if you try to get in my way—
I will dispose of you!
Kadoya Tsukasa!
Such a tiresome nuisance...
Why...?
Tsukuyomi...
You have to... survive.
So these enemies aren't from the Another Worlds...
They appear to come from worlds without Kamen Riders.
I believe that this is a result of the Riders vanishing once you obtain their Watches.
Now their enemies go uncontested, and unbeaten.
And they gather here.
The catalyst was the Watches breaking.
Why did they break in the first place...?
And the Sky Wall, and that strange tower?
I believe this too is due to the disruptions in space-time.
So in other words, Zi-O is at the eye of this storm.
Maybe Tsukuyomi, too.
Her as well?
Swartz and Tsukuyomi are from the same timeline...
Now I see...
I believe I know what my overlord is after.
Now what?!
Why would he do that for my sake...?
We'll have to ask him, won't we?
Ask him...?
I wasn't intending to use this right now, oh well...
That's...
ZI-O II
Kaito?
Hey, Tsukasa. So, you just died.
Maybe now you can eat some sea cucumbers.
So you rewound time?
Yeah, but this treasure has some...
...side effects!
ZI-O II
Time to take my final treasure... Tsukasa's life!
The Another Rider is controlling him.
Toss me my Watch!
This...?
D-D-D-DECADE!
Transform.
KAMEN RIDE: DECADE
Tsukasa, you're not supposed to have your Rider powers anymore.
I figured this might happen.
So I stashed away half of my power in that watch!
I should have known...
But half your power isn't enough to beat me!
Wanna bet on that?
KAMEN RIDE: ZI-O
KAMEN RIDER ZI-O!
What the...?
Fight Zi-O with Zi-O, as they say.
That means you, too!
GRAND ZI-O!
ADVENT COMPLETE TURN UP
CHANGE: BEETLE
SWORD FORM
Transform!
WAKE UP
KAMEN RIDE
GRAND TIME!
REJOICE!
KAMEN RIDER GRAND ZI-O!
KIVA!
FOURZE!
DRIVE!
My treasure...!
You never stop causing trouble, do you?
Come on.
Tsukasa...
You should be grateful.
The Grand Zi-O Watch...
Now I get it, more or less.
It's like the end of the world...
I'm going to destroy this world.
Next time, on Kamen Rider Zi-O...
The power to destroy space and time!
At world's end...
I'm a Kamen Rider.
At world's end...
Sougo makes his choice!
I had... a friend?
Sougo makes his choice!
She's going to save the world!
Sougo makes his choice!
One last trip through time...
Oma Time
Be safe out there!
