After the events, the setting takes place in a abandoned warehouse.

Naoya Kaido was seen sleeping, as he immediately opened his eyes.

Koemi: Y/n, Mihara, this guy's awake!

Kaido: Oh man, I feel like I've been hit by a truck.

Mihara: How are you feeling, Naoya Kaido?

Kaido: Eh, good I guess.

After saying that Yuka Osada awoke and got up as well.

Osada: *grunt*Where am I?

Koemi: Hey, are you okay?

Osasda: Y-Yeah. Mihara! You're alive. I thought Kusaka said you died.

Kaido: Alright, enough talk, where are we anyway?

Mihara: An abandoned warehouse, about a mile from the base. Y/n was able to save you from that giant orphnoch.

Osada: I see. Thank you.

Kaido: Hey, where's Kiba?

Everyone was in silent.

Y/n: That horse guy was about to be eaten by that monster. I only managed to get you all out of there, but I couldn't save him.

Kaido: What... did you say?

Osada: No... it can't be.

Kaido: ...You bastard!

Kaido then grabbed Y/n and pinned him against the wall while showing his orphnoch face.

Kaido: You, a human, left Kiba, an orphnoch for dead!

Y/n: If that's how you see in me then go ahead, I'm not afraid to die.

Kaido then hesitated and let go of Y/n.

Kaido: Damm it!

Osada: I'm sorry, he's just frustrated.

Y/n: Don't bother, you guys have the right to be mad at me.

Osada: But, at least you saved us, thank you. *bows*

Mihara: Anyway, what were you three doing at Smart Brain anyway?

Osada: ...We were driven out from the Liberation Army. We went to Smart Brain to steal the Emperor Belt so we can prove ourselves, but we...

Mihara: I see. I'm not surprised, everyone did have a grudge against you three.

Koemi: Um, sorry to interrupt. But what do we do now?

Kaido: I can't stand this anymore, I'm going back to Smart Brain to finish what we started.

Y/n: In that case, I'll come too.

Kaido: What?

Y/n: Think of it as my way of saying sorry for what I did earlier.

Kaido then stayed silent.

Koemi: In that case, I'm coming too.

Mihara: We're all going.

Osada: You guys, you don't have to...

Y/n: It's no doubt Smart Brain we'll be ready. And by the looks of it, you guys need all the help you can get.

Kaido: Fine, but if I find you planning something, I'll burn you to a crisp.

Y/n: Whatever you say.

Later...

The group is walking down the road when they come across someone.

It was Keitaro Kikuchi, who was just standing in the middle of the road with his bike broken and a pile of weapons on the floor.

Mihara: Hey, isn't that...?

Osada: Keitaro!

Keitaro: Huh? Osada!

Keitaro and Osada then hugged each other, since they have a relationship.

Kaido: Lucky guy...

Osada: I'm so glad to see you again, Keitaro.

Keitaro: So am I, everyone said you, Kiba, and Kaido disappeared and didn't come back. ...Mihara!? Your alive!

Mihara: Yeah, I am.

Koemi: What are you doing all the way out here?

Keitaro: Well, Takkun and I were heading our way to Mari, who was kidnapped.

Everyone was shocked.

Mihara: What did you say!?

Osada: Keitaro, what do you mean?

Keitaro: It was Smart Brain, the Riotroopers just kidnapped Mari. Me and Takkun were on our way to save her... but Takkun left me behind.

Y/n: He must be trying to protect you.

Kaido: Well what do we do now? I mean, we can't let this go right?

Mihara: Obviously we're going to save Mari. Come on, we have to go.

Keitaro: Wait, let me come too!

Mihara: No, it's too dangerous. You should head back to the base.

Keitaro: You sound just like Takkun. Besides, I want to go, Mari is also a friend, and I can't just-

Osada: Keitaro. We'll be the ones to save her.

Keitaro: ...Okay, but please come back safely.

Osada: We will, I promise, okay?

Y/n: Koemi. You should go with Keitaro as well, I don't think it's a good idea to come with us this time.

Koemi: Okay, please be careful Y/n.

Mihara: Okay, let's go!

Later...

Y/n, Mihara, Osada, and Daigo arrived at Smart Brain Arena.

Y/n: Is this the place?

Mihara: Yeah. Smart Brain Arena, the place hosted for Orphnochs to watch public human executions.

Osada: Mari is definitely inside.

Kaido: Okay, we go in, save her, and get the heck out of there with the Emperor's Belt.

Mihara: Alright. Let's go!

Meanwhile...

Everyone managed to infiltrate and get inside, finding themselves on the top floor and watching the arena.

Y/n: We're here.

Kaido: Dang. Look at how many orphnochs there are.

While looking at the scenery, Mihara sees Mari in a cage.

Mihara: There's Mari!

Osada: Hey look, isn't that...?

The four see Kamen Rider Faiz, Takumi Inui against Orga, who is actually Yuji Kiba.

Mihara: Takumi.

Y/n: Which one?

Mihara: The one in red, over there.

Y/n: But who's the one in black?

Osada: That's...

Kaido: The Emperor's belt. Alright, now this makes it a lot easier!

Y/n: Wait. Let's sit back and watch just a bit, we'll wait for the right time to act.

Mihara: Right.

[There should be a GIF or video here. Update the app now to see it.]

(start from 0:38 to the end)

After the battle, the Elasmotherium orphnoch was ready to eat Mari in her cage.

Faiz: Mari!

Mari: Takumi!

But then suddenly, a shot was fired that broke the cage's chain and Mari is seen falling.

But only for Takumi to grab her and put her in a safe distance.

Faiz: Mari, are you okay?

Mari: Yeah, I'm fine. But, what was that?

Delta: Looks like waiting for the right moment worked.

It was Mihara already in his Delta form who was responsible for earlier.

Faiz: Mihara!

Mari: Mihara! *comes up and hugged him*You're alive, thank goodness.

Mihara: M-Mari.

Osada: Takumi.

Faiz: Osada. Kaido. You're here too?

Takumi turned his face towards Y/n.

Faiz: And... who are you?

Y/n: Y/n L/n. Guess you can say I'm the one who saved your friend here.

Faiz: Is that so?

However, their reunion was cut short when the Elasmotherium Orphnoch's cage was set free.

Y/n: Guess this reunion will have to wait.

Ridewatch: (Digital beeping) Zi-O!

Y/n: Henshin.

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

For a while it was just, Y/n, Takumi, and Mihara fighting the Elasmotherium.

Then when it was time to finish it off, Mihara was the first one to pull off his finisher.

He started to shoot out an energy drill and performed his rider kick.

While the Elasmotherium was suffering from that damage, it was Y/n and Takumi's turn.

Y/n grabbed his ridewatch and put it on his Zikan Girarde. Then Takumi pressed enter on his Faiz Blaster.

Finish Time! Sure Sure Shooting!

Faiz - Exceed Charge!

Y/n and Takumi the fired their attack and destroyed the Elasmotherium, turning it to a pile of dust.

Everyone then went to the three riders' side, who all de-henshins.

Mari: Guys, are you okay?

Y/n: Yeah, we're fine. Looks like it's over.

Kaido: Not yet. *turns his sight on Orga*We still need this guy's Emperor belt.

Orga: Kaido... is that you.

Kaido: *shocked*What the?

Osada: That voice. It can't be...

Kiba de-henshins and most of the group was in complete shocked.

Mihara: Kiba... he's alive.

Kaido: No way.

Kiba: Kaido, wait, I can explain.

Kaido then punches Kiba out of rage.

Kaido: Kiba, you idiot! You betrayed us!?

Kiba: Stop Kaido! I only thought-

Kaido was then about to punch until Takumi stops him.

Takumi: Stop it. At least let him talk.

Takumi then helps Kiba up, which he accepts.

Kiba: I... I thought you and Osada died.

Kaido: *scoffs*No way man, we wouldn't die like that. Are you stupid?

Osada: It was Y/n here who saved us.

Mihara: Why would you side with Smart Brain, Kiba? I thought you wanted humans and orphnochs to co-exist.

Kiba: I betrayed it because... because she betrayed the three of us.

Kiba then points to Mari.

Mari: Me?

Kiba: I saw you, saying that you set us up and betrayed us.

Mari: But, but I wasn't there! The last time I saw you was you three left for Smart Brain.

???: She's telling the truth!

All of a sudden, Koemi came in running to the group.

Y/n: Koemi, what are you doing here!?

Keitaro: Wait, Koemi!

Takumi, Mari & Osada: Keitarou!?

Keitarou: *gasp*Takkun! *runs and hugs him*You're okay, I'm so relieved.

Takumi: What are you doing here, Keitaro!?

Keitarou: I'm sorry, I'm sorry. I tried to stop Koemi, but instead she ran all the way here.

Koemi: Kiba, right? Here, there's something you need to see.

Koemi then showed a video she took of Smart Lady transforming into Mari.

Kiba: No way. I was manipulated?

Kaido: *grabs phone*Whoa, that explains a lot!

Kiba: ...Mari, Takumi, I'm sorry.

Takumi: No it's fine.

Mari: And I'm sorry too, that you believed and suffer all that.

Suddenly, everyone in the arena was cheering as the signs say "Lucky Clover".

It shows two orphnochs coming out to the spotlight.

Takumi: Those guys...

Keitaro then got a radio call from the army.

Keitaro: Hey, who's this?

Radio: Keitaro, we heard our leader was kidnapped and you went to save her. We're coming in to support you with reinforcements.

Keitaro: Eh!? No wait-! *radio cuts off*

Mihara: Not good, the army is in trouble.

Y/n then looks at the emperor's belt on Kiba, then turns to see the two orphnochs approaching.

Y/n: I'll handle these two, you all should go and help your friends.

Osada: By yourself?

Takumi: What are you talking about!? Those two are from Lucky Clover, they're too strong for one person.

Y/n: With my power alone, probably. But with the help of another...

Y/n then holds out his ridewatch and pointed towards Kiba.

Kiba: What are you doing?

Then, the emperor's belt and Orga Phone got absorbed, turning the blank ridewatch to the Orga Ridewatch.

Kaido: D-Did you just...?

Y/n then turned to the orphnochs.

Y/n: *puts on belt*Now then, bow down to your king.

Y/n then puts on both the Zi-O Ridewatch and the Orga Ridewatch.

Ridewatch: (Digital beeping) Zi-O! (Digital beeping) Orga!

Y/n: Henshin.

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

Armor Time! (Death metal music mixed with Orga Phone dial tones) Complete! Orga!

The group and everyone in the crowd were shocked to see Y/n in that state.

Kiba: How did you do that?

Zi-O (Orga Armor): I absorbed your power and made it my own. Leave this to me, you all should hurry up and get out of here.

Takumi: ...I understand.

Mari: But Takumi...!

Takumi: I'm pretty sure he can take care of this himself...

Kiba: Takumi's right, we need to worry about the others.

Everyone then nodded in agreement, and even Mari did too.

Takumi: Then, we'll be leaving the rest to you!

The group then left.

Zi-O (Orga Armor): Hmph, you don't have to tell me twice. ...*turns to the orphnochs*I believe your times are up.

Y/n then engaged with the two orphnoch.

Due to having the orphnoch's level of power, he was able to over power the two orphnochs so easily.

He even attacked them with his Orgaphone Ω in blaster form.

note: the red is actually gold-color.

After the two orphnochs were pushed back, Y/n held out his Orgaphone Ω.

Orgaphone Ω: *press number button*0-0-0. *presses "enter"*Ready! Stlanzer On!

Suddenly, Y/n's primary weapon from his armored form appears in front of him in the shape of a sword, the Orga Stlanzer Stlanzer. Which appears quite similar to the SB-000S Orga Stlanzer.

The Centipede Orphnoch then engages Y/n alone, but was ultimately defeated after two powerful slashes, causing him to be frozen and fade away to dust.

Y/n then focused on the Lobster Orphnoch, and then pressed both of his ridewatches and turned his driver.

"Finish Time! Orga! Exceed Time Break!"

Y/n first jumped high in the air and pointed his sword on the Lobster Ophnoch and extended it to hold her down. Then he threw his sword, turning it into a massive energy drill. Y/n then performed his rider kick, which completely destroyed the Lobster Orphnoch for good.

Y/n then stood victorious, while the orphnochs in the crowd are shocked and scared of Y/n.

Meanwhile...

Outside, Takumi and the rest of the Human Liberation Army are successfully securing Smart Brain and killing all orphnochs.

With their total capture of Smart Brain, and Takumi killing all the high Executives in charge of Smart Brain, even holding Smart Lady hostage, the humans have declared their victory.

Soldier: You know for once, I was wrong about you. You really are the savior.

Faiz: Right. ...It's over.

To be continued...
