Y/n and Koemi are immediately in another time back in their world, the year 2012.

The two are first seen walking around the city, trying to find another rider so Y/n can take their powers.

Koemi: Y/n, do you think they will really be okay?

Y/n: ...

*flashback*

It was right after Y/n battle with the two orphnochs and the Human Liberation Army. Y/n and Koemi are about to leave.

Y/n: ...Well, now that we helped you and got what we were here for, It's time for us to go.

Mari: Thank you, Y/n and Koemi. For everything you've done for us.

Mihara: Are you going to be alright from here?

Koemi: We should be asking you that.

Takumi: It will take a while for everything to be under control now that we seized Smart Brain.

Kiba: But with enough time, I'm sure both sides will find a way to live in peace.

Kaido: Hey, what're you going to do with that anyway?

Y/n then grabbed and looked at his Orga Ridewatch.

Y/n: I need this to become king, and save our world.

Takumi: I see. But let me give you some advice, Y/n. Becoming a king, isn't just about saving the world.

Y/n: What makes you say that?

Takumi: I'm pretty sure you'll understand someday.

Mari: But really, thank you for giving us this chance for our future.

Y/n then summoned his ridestriker and both him and Koemi got on and gone through the portal.

*present*

Y/n: *thoughts*Not just about saving the world... Just what do you want me to learn, Takumi?

Y/n and Koemi then were surprised by the sudden arrival of the cloaked man.

Koemi: Hey, it's-

Y/n: Old man.

???: It's been a while since we met, Y/n. I see you even managed to obtain two more ridewatches. Cronus, the final boss of a never-ending game and the ruler of time, Ikaros, the being created by Virgo and the Nadeshiko, as well as Orga, the secret weapon created for the orphnochs. I am quite impressed, so I thought I might give you these as a reward.

The cloaked man then gave Y/n two ridewatches.

Y/n: New ridewatches, what do they do?

???: You will know soon enough. Until then...

Then the cloaked man disappeared.

Koemi: I think it's nice of him to give yout these. I hope they can help us in the future.

Y/n: Yeah, I wonder about that too.

Koemi: ...Hey, Y/n. Look!

Both were looking at a shop called "Donut Shop Hungry".

Y/n: That's a donut shop. Do you want one?

Koemi: *nods*Please.

So, both went to the donut shop, runned by Yu Kamimura and Ryu.

Kamimura: Ah, new customers! Welcome~!

Ryu: Come, come see our selection.

As they looked, the donuts look so good.

Y/n: Is there anything you want, Koemi?

Koemi: Hmm, I'll take... this one with pink frosting.

Kamimura: Ooh, good choice. It matches you. Oh, and do you want one as well, good sir?

Y/n: Ah, no I'll just take plain sugar.

Ryu: Then, coming right up!

Y/n and Koemi then took a bite out of their donuts.

Koemi: Mmm~ It's so good!

Y/n: I'll admit, it's not bad.

Y/n and Koemi then walked away.

Koemi: Thank you!

While walking, Kamimura and Ryu are staring at the two.

Kamimura: You know, Ryu. That boy reminds me of Haruto.

Ryu: Oh yeah, I guess you're right. I wonder where he is though? He hasn't come here for days.

Later.

As Y/n and Koemi are still walking they bumped into someone in a yellow jacket.

Koemi: Ah, are you okay!?

???: Ah, yes yes, sorry about that!

It was Shunpei Nara, who was then helped up by Koemi.

Shunpei: Ah hey, have you two seen this person anywhere?

Shunpei then shows a picture of Haruto Soma, Kamen Rider Wizard.

Y/n: No, we don't know him.

Shunpei: Oh...

Koemi: Did something happen to him?

Shunpei: Yeah, this person, Haruto, we haven't found him for days. Now we're trying to find him.

Koemi: Maybe we can help.

Y/n: Koemi!

Koemi: Y/n, he needs our help! Please?

Y/n: *sigh*Fine, we'll help you find this guy at least for a bit.

Shunpei: Really? You mean it? Thank you, thank you so much! My name is Shunpei Nara, nice to meet you.

Y/n: Y/n and Koemi, nice to meet you, I guess.

Later...

Shunpei led the others towards the Antique Shop Omokagedo.

They later meet Shigeru Wajima and Rinko Daimon.

Wajima: Ah, Shunpei you're back! Um, but who are they.

Shunpei: Oh yeah, this is Y/n and Koemi. Y/n and Koemi, these two are Wajima, who runs this shop, and Rinko, a police officer.

Koemi: Nice to meet you.

Rinko: Nice to meet you too. But why are you two here?

Y/n: We decided to help you guys find this Haruto person.

Rinko: Shunpei, why did you drag them into our problems?

Shunpei: W-Well, they offered to let them help us, so I couldn't say no.

Wajima: I think it's a good idea, the more the merrier, right?

They then heard the door open to find Nitoh Kousuke, Kamen Rider Beast, and the familiars returning.

Wajima: Nitou.

Rinko: Nitoh, did you manage to find Haruto and Koyomi?

Nitoh: Nah, we looked everywhere, but we found nothing. Huh, who are these guys?

Y/n: We are-

Nitoh: Don't say it! Let me guess, you guys are here to help us out.

Y/n: What's with this guy?

Koemi then took a look at the familiars.

Koemi: Aww, who are these little guys? They're so cute!

Wajima: Those are Haruto's familiars. They help us find phantoms and other things.

Y/n: Phantoms?

Rinko: Monsters who look like humans who drive others to despair to make more phantoms.

Nitoh: Haruto and I are in charge of eating them up.

Y/n: I see... guess that's why he's gone missing.

Shunpei: Hey hey, what do we do now? Do we have another way of searching for Haruto and Koyomi?

Y/n then heard some noises to the two new ridewatches. So he grabbed them out and pressed them.

They then transformed into small robot forms, one a bird, another a samurai.

Everyone started to get surprised.

Rinko: Whoa, what are those that you have Y/n?

Y/n: That's what I want to know.

Koemi: I think they can help, just like with these little guys.

Nitoh: Alright. Looks like we have our another way.

Rinko: Right, but let's look for Haruto and Koyomi tomorrow, we all had a long day.

The next day...

Everyone was back in full gear and searched for Haruto and Koyomi everywhere.

After a long search, the samurai ridewatch came back to Y/n.

Y/n: What is it, did you find something?

The ridewatch then threw a graphic window, showing the bird ridewatch where Haruto and Koyomi are.

Y/n: I think that's them, better get the others.

Later...

Everyone got together again, being led by the samurai ridewatch on his hand. That's when they arrive.

Rinko: You sure this is the place?

Y/n: That's what this little guy told me.

Nitou: Then that means Haruto and Koyomi are at the top of that roof.

Rinko: Let's go.

But as they are going, Y/n then saw a rainbow color up at another roof.

Seeing this is important, Y/n decided to go check it out.

Meanwhile.

That rainbow color phenomenon Y/n saw was actually a portal. And who went through it was Orma, Kamen Rider Sorcerer.

Normally, he would've been destroyed, but in Y/n's world, it proves that Orma was destroyed virtually. Now, he's alive in reality.

Sorcerer: *grunt*Curse you Wizard... But don't think this is the end. I will simply create a new world, and the next time, I will make sure give birth to many phantoms! Just you wait, I will have my revenge...

Y/n: So that's the reason.

Y/n then appeared on some stairs and approched Orma.

Sorcerer: And you are?

Y/n: No wonder the others had a hard time finding Haruto, it was all your doing.

Sorcerer: You... who are you? And how did you know that?

Y/n: Sorry, but I don't feel like introducing myself to someone who's a failure.

Sorcerer: What did you say? Who do you think you are?!

Y/n: That power you have, to create a world. I want that kind of power of yours. And to do that-

Y/n then grabs his Ziku Driver and puts it on.

Y/n: I'll just have to destroy you.

Y/n then grabbed his ridewatch.

Y/n: Now then, bow down to your king.

Ridewatch: (Digital beeping) Zi-O!

Y/n: Henshin.

"Rider Time! (Electronic guitar) Kamen Rider Zi-O!"

Zi-O: I believe your time... is up.

Sorcerer: You little... It will be your time!

Orma engages and Y/n decided to do hand-to-hand combat for now.

After a little time passed, Orma used lightning to strike Y/n, but he dodged it.

Y/n then summoned his Zikan Girarde in Ken form and managed to land some blows.

Y/n then switched his weapon to Zyu form and fired some shots. However, Orma then used reflect to block those shots.

Orma then used dupe, then used blast and send explosions to Y/n.

Y/n got down on the ground but got back up.

Y/n: Not bad, but let see how you'll go against this. *grabs a ridewatch*

Ridewatch: (Digital beeping) Ikaros!

Y/n then inserted and turns his driver.

Armor Time! (Ikaros Driver standby auto-tuned sound music) Ready, Ikaros! Ikaros!

The armored parts of Ikaros appeared, floating while performing the pose of slowly raising its arms and crossing them. Then, it transformed to Wing Mode, and flew around for a bit before it and the kanji were installed onto Y/n.

Sorcerer: *evil chuckle*No matter what you do, you will never defeat my magic!

As Y/n and Orma are battling again, Y/n got the advantage by attacking him with his bird-like drilling claws.

Orma then tried to struck him with lightning, but Y/n transformed to his Wing Mode and flied around to dodge all lightning bolts.

Y/n: Hmph, you were already finished before it began.

Y/n pressed both watches and turned his Ziku Driver.

Finish Time! Ikaros! Limit Time Break!

Y/n start flying towards Orma, picked him up, and threw him to the sky. Y/n charged his wings to see them glowing all negative red, and with them, slashed through Orma a couple of times in the air, while flying. Finally, Y/n performed his rider kick, which he spinned around like a drill after the moment of impact.

Y/n then landed, transforming back to his original form, with seeing Orma screaming before he exploded while he's still in the air, killing him for good.

Y/n then de-henshins and took out his ridewatch. He absorbed Orma's remains around him, and the ridewatch transformed to the Sorcerer Ridewatch.

While Y/n was starting to be relieved of his victory, he heard a slow clapping noises.

He turned around to see the cloaked man once again.

Y/n: Old man...

???: Seems you did alright, getting another rider's power.

Y/n: Hmph, I thought I told you that I don't care about your congratulatory compliments.

???: But with Sorcerer's death, you managed to lead your world to a safe future once again.

Y/n then saw the other roof where everyone else is, being able to find Haruto and Koyomi and laughing in relief.

Note: Koemi is also there too.

Y/n then chuckled a bit.

???: Although, I must ask, why would you choose the powers of those riders. Haven't you seen that they've done more harm to the world? So why would you choose them instead of the main Heisei riders?

Y/n: Because I saw what they could do, the kind of power they have. Of course the previous riders used it for evil, but with their power as mine, they can do good. You saw what happened in my time and how those robots destroyed my home easily. That's why I need an incredible power, the power to save the world.

???: I see... A power to save a world? I'm sorry to say, but the powers of those dark Kamen Riders you have there, are not the power to save the world.

The cloaked man then disappeared, leacing Y/n puzzled.

Meanwhile...

Everyone was happy, but Koemi then looked around.

Rinko: What's wrong, Koemi?

Koemi: It's Y/n, where is he?

Rinko: Huh, he was behind us a while ago...

Back to Y/n...

Y/n then stared at the five ridewatches he has and thinked for a minute.

Takumi(flashback): Becoming a king, isn't just about saving the world.

???(flashback): I'm sorry to say, but the powers of those dark Kamen Riders you have there, are not the power to save the world.

Y/n: ...Just what are you trying to say? What is the power to save the world?

Y/n then just stood there while continuing to look at the view of the city.

To be continued...
