No Pov.

=====>Underground Cave<======

When Shadoom and Ozzy took Yuri to the underground cave, he looked around the cave and he saw a secret entrance ahead, Ozzy pulled a rock lever and it opened a secret door.

Ozzy: Let's go see the city that we helped our friend that he built. 

Yuri: *confused* What city?

Shadoom: *smiles* You'll see, my friend. 

They walked through the entrance, but they were followed by Sakura Suzuhara hiding behind the rock.

Sakura: Hmm, I better follow them or I don't wanna get caught. 

She went in there as well, but Shadow Moon stopped in front of the entrance and he growled.

Shadow Moon: *growled* I can't go there, that city is filled with Kaijns. I cannot go back there again ever since my mentor told me about it, the Original Shadow Moon. I will be back later, but first.......A.R.K.!

A mechanized monster came inside of the cave.

A.R.K. walked towards him, he turns to him.

S. Moon: I want you to destroy the city, find that boy and bring his Black Sun King Driver to me. 

Ark nodded and he went through the entrance, Shadow Moon went back to his hidden base for his next devious plan. 

=====>Hidden Entrance<======

When they were about to walk towards the light, he opened the doors and the lights revealed it was an underground city.

Yuri's eyes widened and shock at an underground city, Shadoom turned to him. 

Shadoom: *smiles* Yuri Ikari, Welcome..........to Kaijin City. 

Yuri: *confused* Kaijin City?

Ozzy: Kaijin City is filled with humanoid monsters, us heroic monsters built this city for them. The United Nation and Japanese government tries to find these innocent kaijins.

Yuri: No wonder why all kaijins disappeared. 

Shadoom: Indeed, let's go check it out. 

All three friends walked towards the city, then Sakura followed them to the city.

=====>Kaijin City<======

Shadoom and Ozzy are touring Yuri in Kaijin City, he amazes the city that is filled with kaijins. 

Yuri is amazed the city has all kaijins he turns back at Shadoom and Ozzy. 

Yuri: *amazed* This city is amazing, it's almost like Ben 10: Omniverse when Bellwood has an underground city filled with aliens.

Shadoom: Well, these aren't aliens. We are kaijins, human-size creatures, we keep them safe from bad humans. We got laws as well, we gather food, clothing, motorbikes and others for them. 

Yuri: So, how did you guys manage to get them food and supplies?

Ozzy: Disguising ourselves, many humans think we are one of them. The government wants to kill them that bad, many of them have families and others. 

Yuri: No wonder why they're doing this in the first place. 

Shadoom: *nodded* Yeah, but Virgul kept them safe down here to keep them safe.

Yuri: So that's the dragon I saw last night. 

Shadoom: It's seems you already know him.

Yuri: Yeah, he first fought those Raptors and he even fought both Angel and Eva-Unit 02. 

Ozzy: Hmm, looks like Virgul is restoring the Earth's balance to show the Gods what he's made of. 

Yuri: You meaning that he's gonna be-

Shadoom: *nodded* Yep, his title will be The King of Gods and Monsters. 

Yuri: No wonder why he's all powerful.

*BOOM*

They heard a loud blast through the wall, as they turned around and saw A.R.K. glaring at the city and all the Kaijin civilians are running and panicking. Yuri, Shadoom and Ozzy eyes widened at A.R.K.

Yuri: *eyes widened* What is that thing? 

Shadoom: *eyes widened* Oh no! It's Shadow Moon's Mecha: A.R.K. stands for Antagonize Rampaging Kaiju. He's here for you!

Ozzy: We need to get out of here!

When Ark analyzes him, Ozzy and Shadoom, he turns to Yuri and analyzes him completely and he walks towards him. But suddenly, he got blasted by bullets and the trio turned in their right direction and they saw a blonde-haired boy walking towards them holding his Primal Pistol. 

???: *smiles* Ain't this a party, no wonder why this robot was created by Kamen Rider Shadow Moon. Where's the fun and that.

Yuri: *confused* Who are you?

Shadoom: And how did you find this place?

???: My ways. Oh, there's a spy here watching *pointed at the secret entrance* over there. 

He pointed at Sakura and they turned at the secret entrance, she grunted. 

Sakura: Damn it, how did he know I was here? Who are you?

Ethan: *smiles* I am Ethan Fredrick and also......I'm just a passing through Kamen Rider who travels through Space and Time.

He pulls out his PrimordialDriver and puts it on his waist, and he grabs his card out of his Kamen Rider form. 

Ethan: Remember that.

Yuri/ Ozzy/ Shadoom/ Sakura: *curious* Another Kamen Rider?/ Kamen Rider?

Ethan: Henshin!

He puts it inside of his driver and twists the handle.

Announcer: KAMEN RIDE. PRIMORDIAL!

He transforms into Kamen Rider Primordial.

Yuri, Shadoom, Ozzy and Sakura eyes widened at him, Ethan turns at the with his thumb pointed at himself. 

Ethan (Primordial): *smiles* I am also known as Kamen Rider Primordial the King of Kamen Riders and DaiKaiju Warriors. 

Yuri: *confused* Kamen Rider Primordial?

Shadoom and Ozzy: *confused* King of Kamen Riders & DaiKaiju Warriors? 

Ozzy: *serious* That's impossible, how are you're a king of both Riders and Warriors.

Ethan turns around at Ozzy.

Ethan (Primordial): *smirking* Like I said: I'm just passing through Kamen Rider. I am the King, better than Zi-O and Decade. They're my rivals. 

He pulls out his Primal Scanner Gun to scan all Daikaijus and Riders, he pointed at Yuri and he pulls the trigger and it scans him and it summons his card on his right hand. He looked at it and he chuckled. 

Ethan (Primordial): *chuckles* Yuri Ikari, older brother of Shinji Ikari. Poor kid, he went through hell. Even though, good thing you came in, Yuri. You will defeat Shadow Moon soon. I already scan your Black Sun Dragon friend of yours, time for action. 

He pulls out his card of Virgul, and puts it inside his driver and twists the handle. 

Announcer: KAMEN RIDE. VIRGUL!

He transformed into Virgul, everybody's eyes widened at him and even the Kaijin civilians are shocked as well. 

Shadoom: *eyes widened* What in the blazes!

Ozzy: *eyes widened* How did he-

Yuri: *eyes widened* Transformed into Virgul!

Ethan (Primordial/ Virgul): Hmm, this Virgo is different than other versions of Virgo. No wonder why they call him King of Gods and Monsters. Let's crumble, A.R.K. 

A.R.K. roared at him and he charged towards him, Ethan in his Virgul form smirked at him and he flew towards him. He punched him and grabbed his arm and he swung him around and threw him to the wall, A.R.K. eyes are brightened in anger and roared. 

A.R.K.:

He ran towards him and Ethan (Primordial/ Virgul) stepped aside and grabbed his tail, then he slammed him triple times and he finally threw him back to the walls. He pulls out Virgul's finisher card. 

Ethan (Primordial/ Virgul): *smirking* Time for the finisher, let's find out shall we. 

He puts inside his driver, and twists it.

Announcer: FINAL KAIJU ATTACK RIDE. V-V-VIRGUL!

His wings are shining and he jumped up in the air, Ark looked up and his eyes widened. 

A.R.K.: *eyes widened  & robotic voice* Uh oh!

He kicked through him, Ark screeching in pain as he exploded. Then Ethan (Primordial/ Virgul) transformed back into his normal form, he summoned the dimensional wall and he turned back at them and waved goodbye. 

Ethan (Primordial): *waving* We'll meet again, Kamen Rider Black Sun.

He went through the dimensional wall and disappeared, their eyes widened and all Kaijin went back to their business. 

Ozzy: *eyes widened* Okay, that went well. 

Shadoom: *nodded* Yeah *turns to Sakura & glared at her* Except we had a spy that followed us. 

Both Ozzy and Yuri turns to Sakura and glared at her, Sakura giggles nervously. 

Sakura: *giggles nervously* How's it going, boys?

They kept on glaring at her, Sakura sighed and looked down.

Sakura: I'm in trouble, am I?

Yuri: *glare* Not till you answer us.

======>Outside of the Secret Cave<======

Shadow Moon got angered that a new Kamen Rider came out of nowhere.

S. Moon: *growl* Who was that Kamen Rider? How the hell did he defeat my greatest creation? Never mind that, time for Ares to drain all Angels powers and blood to make himself stronger to kill Virgul and I will kill Black Sun. I will destroy him till the end.

As the screen fades black, his eyes are glowing green.
