Chapter 29 Black Rider

I don't own Kamen Rider OOO or Koihime Musō

Kazuma was outside with Shoto, Ankh and Mezool, they were running outside the city to look for any trouble.

"There it is!"Kazuma sees it.

They saw another ritual sumon like the one that made Mezool, near it was the three Shocker Greeeds.

"Hey!"They looked back and sees them with the group transforming.

"Henshin!"Kazuma scans the medals and Shoto opens the orb.

TAKA, TORA, BATTA TA-TO-BA! TATOBA, TA-TO-BA!

POP!

They were now in they're rider forms and they fought the Greeeds off, OOO fights against Shocker Greed with Birth as they slashed and shoot at him.

Mezool was fighting against Gel-Shocker as the creature throws it's arms at her and she dodges while whipping it.

Ankh blasted Destron back making the Greeed grunt.

OOO takes out two metals.

SASORI, GORILLA, BATTA!

He changes and shoots poison at the Shocker Greeed making it grunt before punching it many times and hitting it back.

Ankh blasted it back and said:"Hey Kazuma, use your complete form to blast these guys away."

Birth shoots more medals."Yeah do that."

"Okay."OOO uses two medals.

SAI, GORILLA, ZOU! SAGOZO! SAGOZO!

OOO was now in Sagozo form and he roars and pounds his chest making the three Greeed worried as they were being sent up to the air, OOO pounded his chest making them get sent away and crashed to the ground.

They got up and looked worried.

"Kill him!"Shocker Greeed said.

They charged up orbs of different colors and OOO scans his belt.

SCANNING CHARGE!

They attacked him but he grunts making a forcefield of gravity to stop them, he then saw a vision.

He saw a red humanoid guy talking to other ones, the red one was him and he was once known as the Red Rider.

"Have we come fight each other for a pointless, stupid goal?"Red Rider said."Hating each other, stealing from and even killing one another. It's wrong."He told them.

"We lead legions and continue to fight each other but it's not because we're enemies! We're Rivals!"

He then saw Black Lotus."I like the way you fight Lotus."

It then breaks and shows him getting a hug by her.

"Hey!"Purple Thorn said.

OOO remembers her, she was a girl he loved after he lost Mai, she meant everything to him.

"Calm down Thorn, she is only being nice."He said.

But then his head got chopped off ending his time in that game.

OOO got mad and he pushes the attacks back surprising them.

"What?!"Shocker Greeed said.

OOO's eyes glowed purple and he puts his hand inside of the ground taking out the Medagabryu.

"Get him!"Gel-Shocker Greeed said and they went around him.

OOO inserts a cell medal in the ax and pulls the lever.

GOKKUN! SAGOZO!

OOO charges up the axe and they went towards him but he slashes around him making the three get hit and they got blown away.

A Shocker Medal comes out and Ankh grabs it.

"Run away!"The three Shocker Greeeds ran away from him.

They saw the circle activate and from it came Gamel.

"Gamel!"Mezool runs to his side.

"Huh?"He stands up and saw her."Mezool!"He hugs her.

"There there."She pats his head.

"Well... At least it's a better choice for now."Ankh said.

"Yeah we did it!"Birth celebrates and he saw OOO staring foward."Big bro, are you okay?"

"I remember now."He said.

Birth got shocked."Wait what?! You mean you remember Red Rider!"

"Yes."OOO said.

"Who's Red Rider? Another Kamen Rider?"Ankh asked.

"No, he's something else."OOO said."Let's go back."

They headed back to the kingdom and they went to Kazuma's room, he then explains to them.

"Wait, so your telling me you played some game that is like what those humans played."Ankh said.

"Yes, me and Kazuma played Brain Burst a lot, it's a game from the Network where we played a lot, Kazuma was the leader of the Red Legion Prominence."Shoto looks at his brother who was looking outside."But, his avatar was destroyed by Black Lotus making him lose the game, and you lose all memories of ever playing it."

"If he was the king there, why didn't you try to gain control?"Mezool asked.

Shoto looks down."I didn't think I would be good enough."

Kazuma looks at him."Your wrong Shoto, you could have given them the future they needed, but now I must go back."

"But how, we don't have the Neuro Linkers and you lost your avatar?"Shoto said.

"Maybe I could help."They saw a old man with red eyes.

"Who are you?"Kazuma said.

"I am Zelretch, I have been traveling around the world for sometime, I know how you can go back."He takes out two Neuro Linkers surprising them."These belong to you two."

Shoto and Kazuma took they'res back and put them on.

"They are modified to have the ability to go back even when you are in a different world."Zelretch goes outside."Have fun."He closes the door.

Ankh goes to where he went but when he opened the door he was gone."Where did he go?"

Kazuma and Shoto looked at the Neuro Linkers and put them on.

"We'll be gone for a bit."Kazuma said.

They activated them and they went to Brain Burst right away.

They arrive at a city that was with a dark sky and looked like a battlefield, Shoto now looks like a small red humanoid robot, he has two blue eyes, a blue cape and a sword on his waist, Red Knight.

Calibur looks at his brother and got surprised, he looks like Red Rider but he was black with the arms having arm blades.

He looks back and shows the red visor.

"Big bro?"Calibur said.

"Looks like you can call me Black Rider in this form."He said.

They checked they're status, they had the same skills they had and they have something new, rider belt.

Rider presses the option and his OOO driver appeared."I see, looks like we have the advantage with the rider belt."

"Then we can get stronger thanks to them."Calibur said.

"Yes, now let's look around."Rider said.

They went foward and Calibur goes foward to see what they could find without people knowing who he is.

Calibur then saw a deserted area but theres a creature called a Disaster holding a small red girl.

"Scarlet Rain?"Calibur remembers her.

Scarlet Rain struggles with the monster holding her but then it's head got slashed making it fall off and she was set free.

Scarlet Rain turned towards the direction of the shot and became shocked.

"How? Why!"

Then everyone saw Red Calibur with his sword out.

The kings all saw him from they're areas watching through screens and they got shocked.

"Knight!"Purple Thorn said.

"He's back."Green Grandee said.

Yellow Jester laughs.

White Cosmo stares at him."So the little brother of Red Rider came back."

Black Lotus was with her friends, Silver Crow, Cyan Pile and Lime Bell from the city.

Lotus was shocked to see him."Calibur."

"That's Red Rider's little brother."Pile said.

Scarlet Rain looks at him and laughs."Oh look the scaredy cat is back."

"I am not afraid!"Calibur said.

"Oh yeah, what did you come back to get the title of the king, well too bad i'm the king now! Your brother was so pathetic to die like that!"She said.

"Nobody calls Big Bro that!"Calibur was angry.

"Then how about you say to my face!"

Everyone was stunned to hear that voice.

"It can't be."Lotus said.

Scarlet Rain looks behind her and sees Black Rider walking towards her.

The Red Legion was in shock seeing him, they're former King has come back from the dead.

Scarlet Rain was pissed.

Blue Knight was just as angry.

Green Grandee was deep in thought.

Yellow King laughed.

White Cosmos frowned.

Purple Thorn was crying tears of joy.

"Rider."Thorn she said.

"Hello Scarlet."He said.

Note:Here's OOO's isekai adventure, it's Accel World where he was once Red Rider, yes Red Rider was Kazuma, now he has returned thanks to Zelretch and he got his belt to increase his power, with Gamel back too.
