AN: After doing some thinking and looking at the review for Code Eternal, I thought "Is there room for more Riders other than Lelouch or a few other people in the Black Knights? And, what's happening with them?" After thinking on those two questions I present my latest idea featuring the manga and OVA characters. The story will take place after R1 of Code Eternal and in between R2 so I'll try not to spoil it as best as I can other than the Riders' identities.

Disclaimer: I do not own Code Geass or Kamen Rider.

Code Eternal: Side story

2017 a.t.b; EU; in a forest between France and Germany

"Dammit! Where did he go!?" The Britannian captain questioned. He and his comrades were assigned to guard an information disk with vital information on their upcoming reinforcements but it was stolen and the thief got a head start.

"Sir! I got movement on my radar!" The Captain looked at the radar on his Gloucester and sees one red dot.

"Don't worry, we outnumber him. This shouldn't be too hard." The radar soon went blank and left the squad more confused. Just then a mysterious figure tackled one of the Sutherlands and dragged it away.

"Private! Report!"

"Oh God! NOOOOO….!" The com soon went dead. The Knightmares huddled up anticipating their foe's next turn.

"What do we do, sir?"

"Just stay calm. He can't take all of us down." The figure rush at them again this time it held out its claw and it revealed a hidden blade. It stabbed the Sutherland in the chest and reached for the pilot. It immediately left before they fired.

"Sir, could…could this be the Beast?" Britannians soldiers stationed in the EU heard rumors of a Knightmare that kills with no mercy and leaves no survivors. The damage it leaves behind even looked like it was ravaged by some animal. Some even believed that it was haunted.

"Don't be ridiculous, the Beast is just a rumor." Just then the figure jumped out of the woods and threw its tonfa at one of them. It landed in the cockpit and when the Knightmare itself landed the squad stood astonished at its' features. It was a W0X Type-01 Alexander except its armor was spikier, the red highlights were replaced with black, its hands resemble claws, and lastly the eyes were red instead of green. It then made a gesture like it was roaring.

"Open fire!" The Alexander drew out its' remaining tonfa and attacked while dodging bullets. The Gloucester charged but the Alexander instantly knocked it down. The Captain watched as the Alexander tore through the squad and literally did tear through a few of them with its claws. The Alexander looked at the damage it caused and went to pick up his other tonfa. The Gloucester drew out its MVS and started to stand up slowly. It then started to charge.

"YOU MONSTER!" The Alexander turned to see the Gloucester stabbed through the back of the cockpit. When it was removed the Gloucester fell and the Alexander looked at its mysterious savior. It was a Knightmare that looked like the Guren but was black with silver with a skull face and instead of a huge claw it had a 7-Type arm. It was the Byakuen in its Skull form.

The two cockpits opened revealing two armored men and got on the ground. The one from the Alexander had white spiky armor, red compound eyes which some of it was covered with spikes, and had a W antennae. This was Kamen Rider Fang.

The one from the Byakuen had black armor, silver cuffs and accents, a rib-cage design on his chest, a scarf around his neck, and a helmet that resembles a skull but with crack on the forehead which was covered by a white fedora. This was Kamen Rider Skull.

"Long time, no see, Fang…or should I say, Akito?"

"I can say the same thing to you, Orpheus." The two removed their memories and reverted to their civilian forms and when they did their Knightmares went back to their original shape and color. When Fang transformed he became a young man who was 17 years old, Japanese, blue eyes, and blue hair with a long braid behind. He was wearing a simple blue jacket, jeans, white sneakers, and carried a katana. His name was Akito Hyuga.

Skull took off his hat and transformed and all that was left was a young man the same age as Akito. He had blond hair, green eyes, and was Britannian. He was wearing a gray coat, white shirt, black pants, brown boots, and later placed his white hat back on. His name was Orpheus Zevon.

"What are you doing here?" Akito asked.

"I could say the same for you. I thought the W-0 was destroyed a few months ago. Everyone dead or MIA on the roster, even you."

"That's the official story." Akito pointed out.

"So what really happened?"

"I convinced Lelouch to accept the remaining W-0 into the Black Knights." Akito answered. This caught Orpheus by surprise.

"That's unexpected of you. I thought you didn't really care about any of them and could care less if they died." Orpheus said from his past experience with Akito.

"They still have their skills which are still beneficial against Britannia." Akito coldly said.

"Now that sounds more like you. So, what are you doing here in the EU and not Japan?"

"Someone has to keep an eye on Britannia here and the EU government itself since it's practically a wild card at this point."

"So, you're working for Lelouch, then?"

"I…owe him a favor."

"You are aware this is practically a suicide mission, right?" Akito nodded. "You haven't changed at all Akito."

"What about you? What does Peace Mark want here?"

"Lelouch wants us to cause trouble for Britannia while he's building his forces so I thought one of the best ways is to set up shop in the EU."

"But how did you find me?"

"My group tapped into communications and heard of a Britannian pursuit after someone of your description."

"And this spot?" Orpheus pointed at the smoke and flames the Sutherlands were giving off.

"You don't fool around and speaking of which I could use your help with something."

"And that would be?"

"You see my sources told me that the Glinda Knights are here."

"Wouldn't it make sense because they see your group as terrorists?"

"No, you see they were stationed here weeks ago at a facility here and reported to be guarding something more important than fighting us."

"And, what would that be?"

"That's what I want to know. It might be a GaiaMemory or an experimental Knightmare. That's also why I came here, to see what's going on and I could use your help." Akito thought about it for a few minutes before giving his answer.

"Alright I'm in, it's not like I have much to lose." Orpheus smiled.

"It'll be nice to have a fellow Rider at my back. Just like old times. C'mon let's go before reinforcements come. We'll figure out a plan once we're at my place." Akito nodded and the two got in their machines and left. While leaving Akito asked Orpheus a personal question.

"So, what will we do if we see your sister?" Orpheus then answered in a cold tone.

"At this point, I don't know if I would consider Oldrin my sister anymore."

AN: If you're wondering how they know each other or Eternal's identity or how they got their Drivers or Memories then you would have to read the rest of R1 of Code Eternal which I have not but plan to post. Also if you have any ideas on pairings or Riders leave them in a review or message me. So, review and PM me for any questions.
