Akira: He whispers "Previously on Let the experiment begin war between Seito and Touto has already started so-"

Ryu: Yelling loudly "Hey why are you whispering I can barley hear you!"

Akira: "Shh don't yell or she'll-" Then a cleaver was thrown right near them

Misora: "Shut up both of you I'm trying to sleep."

Ryu & Akira: Both shocked "S-sorry."

Ryu: "She's a bit scary but not as scary as Akeno."

Akira: "God dam it dude." He sighs "Whatever as me, Ryu, And Saji taken care of the guardians and handle barley with "Hygami" and Remocon Bros this was when the genius decided to create something to help with the hazard trigger."

Ryu: "Which resulted in a rabbit Fullbottle 2.0 and then exploded."

Akira: "Then I decided to create something to help form something even more powerful now what will happen next?"
————————————————————————

Akira was in the lab creating something

Akira: "Well this is gonna take a long time."

Ravel: "And how long is a long time?" Ravel appeared behind Akira which caused him to fall off the chair

Akira: "Ahh!!! Ravel don't sneak up on me like that you could have been hurt." In his thought "And dear god I don't want to deal with your brother."

Ravel: "Ha you may be my boyfriend you wouldn't hurt me. Would you?"

Akira: "Uhh...." Then we cut to a flashback of Akira punching Sona when he gone berserk "No." He shakes his head

Ravel: "Figures anyway what are you doing?"

Akira: "Inventing something to save this country from war."

Ravel: She was so confused on what he said "What?"

Akira: "I'll explain later."

Timeskip to two weeks

The fight was about to start as almost about to start but meanwhile back at the lab Akira has already finish building two beautiful inventions while Ravel fell asleep

Akira: "Wow I think we might win." Then he holds up the FullFull bottle

Akira: "I did it!" He yelled which caused Ravel to wake up

Ravel: "Huh?! Did what?" She yawned

Akira: "It's done the FullFull RabbitTank bottle and with a weapon that'll go along. The Fullbottle buster."

Akira: "Now the-" He then just realized that he's screwed as the fight was almost about to start as he looked at his watch "Oh god we better get going."

Meanwhile

Ryu: "Let's show these bastard not to mess with."

Saji: "Yeah. Though where's Akira?"

Misora: "Back at the lab making something."

Ryu: "Well it won't matter all it'll take is two wins and this will be all over." Then suddenly the announcer spoke

Announcer: "Now then we shall go over the rules. In order for a win the opponent surrenders, unable to battle, or force disengagement of the Rider system."

Announcer: "Now Kamen Rider Grease vs Engine Bros."

Then that was when Saji and "Hygami" steps up to the stadium

Saji: "I'll be saying this by the time I defeat you, you'll be history." He pulls out the Sclash Driver

"Hygami": "Bring it." He pulls out the transtream gun and insert the gear engine

Gear engine! Funky!

"Hygami": "Raging mist." Then he pulls the trigger as black smoke appears around him

Engine running gear!

Saji: "My turn." He pulls out the robot jelly and twist the cap and insert it into the driver

Robot jelly!

Saji: "Henshin!" He pulls on the wrench

Tsubureru! Nagareru! Afurederu! Robot in Grease! Buraa!

Announcer: "Begin!" Then Saji charges in on the attack as Ryu, Misora, Taizan, Remocon Bros, Azazel, and Masakuni Mido

Saji: "Hah!!!!"

Then things went down as "Hygami" fired at Saji as he charges through

Saji: "Hah!!! Love! Courage! Friendship!" Every word he said he strikes once

"Hygami": "And those don't mean anything!" Then he pulls out the steam blade and attaches it to the transtream gun into its rifle

Rifle mode!

Gear engine! Funky shot!

Then Saji was blasted by a shot of energy which caused him to fall on the ground as a bit of electricity shock him

"Hygami": "Pathetic." Then Saji gets up

Saji: "You know what. I don't give a crap what you say because as long as I have faith." Then he charges at him while fires the twin breaker "THERE'S NO WAY I CAN LOSE!!!" Then things gone down as his hazard level increase and then "Hygami" does a body slam on Saji and then judo throws him down

Saji: "Time to end this!" He pulls the wrench as he inserts the robot Fullbottle

Single!

Then he inserts the robot jelly on the second slot of the twin breaker

Twin!

Twin finish!

Then Saji was riding on gold jelly as he slashed "Hygami" multiple times

Saji: "Take this!!"

Scrap finish!

Then he gone for a dive kick and ultimately Saji placed him on the ground and then "Hygami's" armor disappears and then he exploded into pieces of machine

Saji: "What the?!" He sees the machinery "Wait could he have?"

Announcer: "By force disengagement of the Rider system. Kamen Rider Grease wins the first round."

Akira: Both he and Ravel made it "Ok we're here."

Ryu: "What took you so long?!"

Akira: In a sarcastic voice "Traffic what else? I made something that will-" Then he sees the robotic parts of "Hygami" "Android?"

Ryu: "Seems like it."

Akira: "Well it makes sense why." Then suddenly Saji's armor disappears as he got tired

Saji: "I did it." Then he walks back to the others "Oh hey look who finally decided to come-" Then he suddenly blushes at the sight of Ravel and then was having perverted thoughts until Akira punches him in the stomach

Akira: "Saji we may be friends but please stop having perverted thoughts of Ravel." That caused Ravel to blush and then kicks him in... his prized possession (If you get what I mean) "Oh also here it is." He shows them the FullFull bottle which was in a case

Misora: "Woah I guess it was worth it."

Ryu: "Ha but you won't have the chance of using it once I win this round."

Akira: "Hope so."

Ryu: "Alright!" He went out to the stadium

Announcer: "Next round: Kamen Rider Cross-Z vs Hellbros!"

Ryu: "Hellobros?" That was when the Remocon Bros shows up as he removes his jacket that covered his face

Ryu: "What?!"

Itsuki: "Let's get things cleared my name is Itsuki Akagi also known as Remocon Bros but Hygami? He was pathetic."

Ryu: "Dam you! Don't make fun of him!" He pulls out his Sclash driver and twisty he cap and insert the dragon jelly

Dragon jelly!

Ryu: "Henshin!" He pulls the wrench

Tsubureru! Nagareru! Afurederu! Dragon in Cross-Z Charge! Buraa!"

Itsuki: "What a brute." He grabs the Transtream gun from the ground and the gear engine and insert it into the transtream gun

Gear engine!

Ryu: "Huh?" He was concussed what's gonna happen next as Itsuki removes it and inserts the Remocon gear

Gear Remocon! Funky match!

Itsuki: "Raging mist." When he pressed the trigger black smoke appears but blue and white gears collided one another

Fever! Perfect!

Ryu: "They...combined."

Itsuki: "Hellbros is here. Now I'll be dragging you to hell."

Ryu: "Oh no."

To be continued

Next time on Let the experiment begin

Ryu: "He's too strong!"

Itsuki: "Welcome to hell. Maggot."

Akira: "The Rider system is not a weapon."

Azazel: "Akira I'll show you how wrong you are."

Azazel: "Why did you're father gave it to you?!"

Akira: "I will end this!"
