Chapter 1: the Kamen rider club reunites!

It's a sunny day in Japan as gentaro is headed to a new location to meet up with the rest of his friends in the kamen rider club to look at a new machine his buddy kengo had constructed with help from a couple scientists. Gentaro didn't care about kengo's new invention,what he cared about more was meeting his old friends.

"Man this is going to be great seeing all my friends again!" said gentaro excitedly.

Gentaro of course had his fourze driver on him just in case if something went wrong but just as he was beginning to get close to the area another motorcycle joins him. This mystery person was wearing a black suit with black gloves and a black helmet on the person spoke.

Hey gentaro, it's been awhile hasn't it?"it turned out to be ryusei.

"Ryusei!?! You came!?"gentaro was shocked he thought that ryusei would be too busy with his Interpol job to come and reunite with the Kamen rider club.

"Yeah I'm here gentaro now come on let's hurry up and meet up with the others I bet there expecting us" after saying that ryusei would start speeding up on ahead with gentaro also keeping pace in his motorcycle. After awhile they arrive at what appears to be a cross between a laboratory and a factory.

"You think this is the place ryusei?"gentaro asks

"No doubt about it gentaro,come on let's enter"gentaro and ryusei enter the building to find a receptionists area.

"Hello what can I do today for you two gentlemen?

Ryusei speaks up first."uh yes I'm Sakuta Ryusei and this is my friend Kisaragi Gentaro and we are here to see our friend kengo utahoshi,can we see him?"

"Oh yes he's been expecting you two along with another group of his friends"

"Oh good the others are here!"gentaro was excited to learn all his friends we're here shun,Mei,tomoko,jk,Yuki,even mr.ohsugi was here gentaro couldn't wait to see them.

Ryusei seeing this decided to say something to gentaro.

"hey gentaro calm down,don't rush off, and cause trouble" but gentaro was already rushing ahead much to ryusei's dismay.

"Gentaro! Hold up!"Ryusei ran off after him and they both soon ended up in the room that the others we're in surprising them all

"Hey guys it sure has been awhile!"gentaro said

"Gentaro!"everyone said

"Gentaro! What did I tell you about-"ryusei stops as he sees the rest of his friends.

"Oh uh hello guys"Ryusei says regaining his composure. Everyone says there hello's and catch up about what they are doing in life. after that was out of the way, ryusei told them how he was able to be here today.

"So originally I wasn't supposed to be here I was on a mission to take down this drug ring but by some luck Kamen rider Accel happened to be around the area and helped me take down the drug ring faster than I anticipated so thanks to Accel I'm here now with you guys, sorry I never said anything I didn't think I would make it but I'm here now"ryusei felt he owed them an explanation as to why he hadn't said anything but tomoko just smiled and spoke a couple words.

"It's ok ryusei your here now" tomoko said happily.

Kengo spoke up."alright now that we are all here why don't I show you the invention?"everyone followed kengo to where the invention was but mr.ohsugi voiced his concern to kengo.

"Kengo are you sure this invention of yours is safe ? I may not be your teacher anymore but I still care about all of you and I wouldn't want anything to happen to you guys."said mr.ohsugi

Kengo replied to mr.ohsugi's concerned question"don't worry mr.ohsugi It's safe I promise I had help with making this device and yes Yuki I did get some sleep and took rests when the work load was too much for me"

"Good cause we wouldn't want you to collapse again"Yuki said.

Kengo continues"alright so here we are"kengo shows them a big room it was close to looking like the rabbit hatch but with what seems to be a big gate in the middle with some scientists near by ensuring the machine is one hundred percent at full capacity.

Everyone was impressed with kengos new invention and patted him on the back but none of them we're more proud than gentaro.

"Kengo I knew you would make something this awesome one day I didn't expect it to be now but I'm glad your showing us this! So what does it do?"

gentaro was now curious as to what kengos machine can do. Kengo replied to his curious friends question.

"This machine gentaro was originally supposed to finally take us to see the presenters but for some reason it did the opposite and instead we ended up with a gate that opens to another world we sent in an exploration team and they came back with sample's of this new world" kengo proceeds to show them plants similar to there own planet visibly shocking his friends except for ryusei even though he didn't show it physically,he was shocked on the inside.

Ryusei begins to think"alright so it was a good idea I brought the meteor drive,knowing gentaro I know he will do something foolish but this is really strange another world that has the same properties as earth it truly is a big universe out there"tomoko noticed that ryusei was deep in thought and decided to hold his hand,this snapped ryusei out of his thoughts and he smiled,ryusei was happy he was able to see tomoko again.

Ryusei thought again"no other place I'd rather be than here with the rider club and tomoko"

Kengo spoke up again"alright guys so the retrieval team also found this oddity" kengo showed them what appeared to be some sort of bullet but when kengo opened the bullet out came a bit of colorful red dust,this greatly confused everyone but gentaro, who was more curious than confused.

"What is that kengo?"gentaro asked.

Kengo answers gentaro."it seems to be a fire elemental type of dust this is really unlike anything on Earth also proving that there is intelligent life on this new world." Upon hearing this gentaro got excited.

"You mean a new world where I can make new friends!"gentaro was excited he wanted to meet whoever was on that planet and become friends with them.

Kengo speaks."gentaro we don't know if this intelligent life is friendly or dangerous so please calm down" gentaro listened to what kengo had to say but gentaro wanted so much to meet these new people and become friends with them.

Shun finally spoke"since this stuff is fire does that mean if we we're to sneeze on it or drop something on it, it could combust or something?"

"Yes shun."kengo simply answered to his jock of a friend.

"So shouldn't you put that away kengo?"Yuki asks worried.

"Yeah I suppose your right Yuki"kengo puts the dust back inside the bullet carefully and puts it back in a bag for safe keeping so they can study it later.

"So while we explored a bit in this new world it turns out that they have breathable oxygen like we do so it's safe for a human to go in." The others we're really impressed and wanted to see this new world for themselves but kengo spoke up again.

"However during there time at that place the team was attacked by some black creatures that had skull parts on there body. No casualties which is great so I decided to reunite the old Kamen rider club to face off this new threat." Upon hearing this gentaro, ryusei,and shun we're eager to face off against these new beasts.

"So let's do this alright?" everyone was ready to have one more mission as a team again to face off a new threat that threatened another world.

five hours later_

After everyone except for gentaro and ryusei had cancelled everything they would do they packed up there stuff for this new world,now everyone was waiting on gentaro and ryusei to tell them if they could go or not. Gentaro and ryusei enter the room with ryusei speaking up first.

"My boss agreed to this"everyone breathed a sigh of relief that ryusei would be able to help.

"I can but I made sure to call the other Kamen riders to tell them that I would be gone so they will be keeping the world safe while we're gone" everyone was now ready to go. Kengo made sure to bring the powerdizer armor with him just in case gentaro and ryusei needed some muscle with them.

"Alright guys is everyone ready to do this? Does anyone have second thoughts? I don't blame you if you don't want to go,I won't force you to go with us you can stay here in the facility if you want." No one said a word but Mei spoke up.

"As the chairman of the Kamen rider club it's my duty to go where ever the rider club will go plus you guys would be lost without me" everyone chuckles at mei's comment

"Plus you guys need someone who can get information easily from people"Jk added.

"Yeah we're all going!"Yuki cheerfully said.

"Even though I can't do much I'll be there to watch over you as the elder of the group" mr.ohsugi stated.

"Alright then we can begin" after that kengo and the other scientists started booting up the machine and just like that a blue portal opens up and an image of some forest opens up taking everyone's breath away at how beautiful the green scenery was.

"I'm so excited right now I can make new friends in another world!" Gentaro said excitedly.

Ryusei again tried to calm down his friend.

"Gentaro calm down remember kengo did say there was those creatures so don't rush off." gentaro listened to ryusei's warning.

"Yeah I know ryusei but I still want to make new friends and see new sites in that world!"

Shun also spoke"yeah ryusei imagine what we could see in this new world ,maybe I could introduce them to American football."everyone chuckles except for tomoko and ryusei who only cracked a small smile at shun's comment.

"Alright then gentaro ryusei we will be entering first alright?" Gentaro and ryusei agree and bring out the fourze driver and meteor driver.

"You guys brought that?"shun asked surprised.

"Yeah I brought mine just in case if we need fourze's power!" Gentaro said

"I brought mine cause of gentaro." Ryusei admitted

Kengo brought the brifecase with the switches and his computer and the powerdizer suit but then kengo remembered something.

"Hey ryusei I have something for you before we enter."kengo goes to his desk and bring's out a new switch the others hadn't seen, it was roughly the same size as the meteor storm switch except it was colored dark blue with some purple lines around it and at the top was a sphere similar to the meteor driver.

"What is that kengo?" Ryusei asked curiously

"I decided to make a new switch for you just in case anything we're to happen, of course I had help, I call it meteor Galaxy storm hopefully this will help you out when we enter this new world."kengo hands the new switch to ryusei and ryusei accepts the new switch and gentaro comments on it.

"Wow that switch looks awesome kengo! Ryusei now you have a new final form besides meteor storm!"gentaro exclaimed happily.

"Yeah your right gentaro I'm eager to try this new switch let's go guys." after saying that kengo,ryusei,and gentaro enter first everything seemed fine until the portal started to go crazy and started zapping at the meteor drive surprising everyone.

"Whats going on! What's the portal doing to my meteor drive!"after that the portal shuts itself off trapping gentaro,ryusei,and kengo in this new world leaving the rest of the rider club on Earth as the machine started releasing smoke as the rest of the rider club starts panicking.

Everyone said in unison"gentaro! Kengo! Ryusei!

No one knew what to do until someone else spoke

"Don't worry they aren't in any danger what we do have to focus on now is rebuilding this machine"everyone looked at the source of the voice and it turns out to be none other than tsukasa kadoya a.k.a Kamen rider Decade

To BeContinued_

A/N: before anyone asks yes I did make up a new switch for ryusei only cause it seemed during fourze's run that meteor was going to get a new form but for some reason nothing and he was stuck with meteor storm so I thought I'd make a switch that was close to fourze's cosmic form but not as powerful see you next time for chapter two!
