Prologue - Kamen Rider Ex-Aid
A man with a white coat can be seen running towards the Seito University Hospital.
"Oh no! I'm gonna be late again." The man said.
After going inside the hospital, he then encountered a nurse, waiting for him.
"You're late again, Emu." The woman angrily said.
"I'm sorry, Asuna. I just forgot something, that's why I'm late." Emu explained.
"Anyway, we've got another Bugster to destroy." Asuna said.
"Do you know where it is?" Emu asked.
"Yeah, let's go!" Asuna said as they ride on a motorcycle and took off to find the patient.
After a long ride, they finally a found their patient: a kid and a woman
"What's wrong?" Emu asked.
"Oh, thank goodness, you're here. What's happening to my son?" The woman panicly said.
"Don't worry, maam. We'll take a look at what's causing this." Asuna said.
Emu then takes out his stethoscope and scans the kid. And there, he found a yellow object on his neck.
"There. I've found it!" Emu said.
"What is it?" The woman asked.
"A Bugster has infected your son." Asuna explained.
"What? Bugster?" The woman asked.
"Yes. If we don't extract the Bugster out of there, your son will be gone." Asuna explained.
"Alright, leave it to me!" Emu said, as he took out a Gamer Driver and puts it on his waist.
However, the Bugster already took over the kid's body and prepares to attack the three.
"What is happening? My son..." The woman said.
"Don't worry, maam. I'll save your son." Emu said as he took out his Gamer Driver and wears it on his waist.
He then took out his Mighty Action X Gashat and activated it.
MIGHTY ACTION X!
A pink energy can be seen coming out of the Gashat and blocks starting to appear on the field. Emu suddenly smiles and performs his transformation gesture.
"Henshin!" Emu shouted as he puts the Gashat into the Gamer Driver.
GASHAT!
A character select screen rotating around Emu. He then selects the Ex-Aid portrait and begins transforming.
LET'S GAME! METCHA GAME!
MUTCHA GAME! WHAT'S YOUR NAME?
I'M A KAMEN RIDER.
He now transforms into Kamen Rider Ex-Aid Level 1, which is a rather super-deformed rider. He then took out his Gashacon Breaker.
GASHACON BREAKER!
"Alright! Let's clear this with no continues!"
He then starts to attack the Bugster while Asuna gets the woman out of the field to avoid being damaged.
But the Bugster seems too powerful for him to beat. He was about to give up until another man in a white coat arrives.
"It seems you require my help, Intern." The man said as he wears his Gamer Driver.
"Hiiro! You're in time. That Bugster is too powerful for him to take out." Asuna said as Hiiro took out his Gashat and activates it.
TADDLE QUEST!
A blue energy came out and treasure chests starts appearing on the field alongside the blocks. He then twirls the Gashat once and shouts:
"Henshin..." Hiiro said as he inserts the Gashat into his Gamer Driver.
GASHAT!
LET'S GAME! METCHA GAME!
MUTCHA GAME! WHAT'S YOUR NAME?
I'M A KAMEN RIDER!
After transforming into Kamen Rider Brave Level 1, he then took out his weapon.
GASHACON SWORD!
"Proceeding with Level 1. Separate the Bugster from the patient." Hiiro calmly said as he begins attacking the Bugster alongside Ex-Aid.
The battle went on, but Ex-Aid and Brave managed to weaken the Bugster long enough for Ex-Aid to finish it off.
"Take this!" Ex-Aid then pummels the Bugster with his hammer, killing the Bugster. The kid gets out of the virus and Ex-Aid catches him.
"Don't worry. You're safe for now!" Emu said to the kid.
The kid then goes to where her mother is. Then, the Pocket Bugster appears alongside his army.
"Damn you, Riders! I was so close into controlling that kid." Pocket Bugster ranted.
"Oh? Sorry, but I will not let you get into that kid." Emu replied.
They were ready to go to Level 2, but suddenly, another Rider appears. This time, he resembles Ex-Aid except he's black and has a bicycle parts stuck into his chest.
"I won't let you do that." The black Ex-Aid said.
"You again... Why do you intend to get in our way?" Hiiro said as the black Ex-Aid takes out the Shakariki Sports Gashat from the Gamer Driver and inserts it into the Kimewaza Slot Holder.
GASHAT! KIMEWAZA!
"Here it comes!" Emu said as he's about to run.
"Everyone, run!" Asuna shouted.
The black Ex-Aid then press the button again and he performs his Critical Strike.
SHAKARIKI CRITICAL STRIKE!
He then throws one of it's wheels into Ex-Aid and Brave, who tried to avoid it, but to no avail. That caused a lot of damage to them, reverting them back to normal. After that, the black Ex-Aid is gone alongside the Pocket Bugster.
"He ran away... and the Bugster too." Emu said.
"Is he somehow connected to the Bugster?" Hiiro asked.
"I don't know. Right now, we need to find that Bugster before the kid dies." Asuna said.
"But first, we must bring this kid to the hospital." Emu said.
"I'll bring him to the hospital. You two go find that Bugster." Asuna replied.
Emu and Hiiro then runs off after the fleeing while Asuna brings the kid to the hospital, with her mother coming along.
After a long search, they finally found the fleeing Bugster.
"I've been waiting for you, Riders." The bugster said.
"This time, you won't get away!" Emu angrily said.
"We'll see about that!" The bugster said.
The two then wears their Gamer Driver and activates their Gashat.
MIGHTY ACTION X!
TADDLE QUEST!
"Henshin!" Both of them shouted.
GASHAT!
LET'S GAME! METCHA GAME!
MUTCHA GAME! WHAT'S YOUR NAME?
I'M A KAMEN RIDER!
"Dai-Henshin!" Emu shouted as he prepares to flip the lever of his Gamer Driver.
"Proceeding with Level 2." Hiiro said as both of them flip the lever to the other side.
GACCHAN! LEVEL UP!
A portal then appears in front of them and both of them run into it.
MIGHTY JUMP! MIGHTY KICK!
MIGHTY MIGHTY ACTION X!
Emu now becomes Kamen Rider Ex-Aid Level 2 and then poses.
TADDLE! MEGURU! TADDLE! MEGURU!
TADDLE QUEST!
Hiiro now becomes Kamen Rider Brave Level 2. After that, they then take out their respective weapons.
GASHACON BREAKER!
GASHACON SWORD!
They then proceed to fight the Pocket Bugster and his army. Meanwhile in the hospital, the kid from earlier is struggling and is on the verge of disappearing.
"Oh no! What is happening to my son?" The mother said in a panic.
"He's gonna be fine. We just gotta believe on those two to beat the Bugster." Asuna answered.
"What do you mean?" The mother asked.
"Once that Bugster is destroyed, your son will recover instantly." Asuna explained.
Back at Ex-Aid and Brave, the two seems to be able to take out his armies. But before they could attack the Pocket Bugster, they were attacked by a green Bugster.
"You're that Bugster who is a criminal!" Hiiro said.
"I will stop you, Riders!" The green Bugster said.
But then, a voice can be heard.
"Hold it right there, Graphite!"
All of them then looked at where that voice was. And a white-haired man with a white coat appears.
"Taiga..." Graphite called his name.
"What's he doing here?" Hiiro asked.
"Don't worry, I'm not here to take your Gashats. I'm here to settle things with Graphite!" Taiga said as he wears his Gamer Driver.
"Hmph! You're still upset about what happened five years ago?" Graphite taunts him.
"Shut up! I'll destroy you, Graphite!" Taiga shouted as he activates the Bang Bang Shooting Gashat.
BANG BANG SHOOTING!
A yellow energy came out of the Gashat and barrels containing green liquid starts appearing on the field.
He then twirls his Gashat like how cowboys twirls their revolvers and shouts:
"Henshin!"
He then twirls it once more before inserting into his Gamer Driver:
GASHAT!
A character select screen then rotates around Taiga. He then picked the Snipe portrait by shooting it and he began transforming.
LET'S GAME! METCHA GAME!
MUTCHA GAME! WHAT'S YOUR NAME?
I'M A KAMEN RIDER!
"Second tactics..." Taiga said as he flip the lever on the other side.
GACCHAN! LEVEL UP!
BABANGBANG! BANGBABANG!
YOW! BANG BANG SHOOTING! GO!
Taiga now becomes Kamen Rider Snipe Level 2. He then took out his weapon.
GASHACON MAGNUM!
"Mission, Start!" Taiga declared as he tries to shoot Graphite, but Graphite managed to dodge them.
While Snipe fights Graphite, Ex-Aid and Brave then turns their attention to the Pocket Bugster and begins attacking them.
The battle went on and on. Ex-Aid and Brave were able to weaken the Pocket Bugster while Snipe is having trouble against Graphite.
"What's wrong? Did all those five years of training slow you down?" Graphite taunted.
"I told you to shut up!" Taiga angrily said as he managed to shoot him in the belly with his Gashacon Magnum, which caused some damage.
"Not bad..." Graphite said.
Meanwhile, Ex-Aid and Brave were about to use their finisher on the Pocket Bugster.
"I'll finish you with this special attack!" Ex-Aid said as he pulls out his Gashat from the Gamer Driver and inserts it to his Kimewaza Slot Holder.
"There's nothing I cannot cut!" Brave said as he did the same thing as Ex-Aid, except he inserts it into his Gashacon Sword.
GASHAT! KIMEWAZA!
Ex-Aid can be seen preparing for a devastating attack, as his left leg is charging, while Brave's sword is charging as well. Ex-Aid then presses the button once more.
MIGHTY CRITICAL STRIKE!
Ex-Aid jumps and performing several flurry of flying kicks on the Pocket Bugster, then Brave charges towards the Bugster with his sword.
TADDLE CRITICAL FINISH!
Brave then performs a wide slash that permanently finished off the Bugster for good.
KAISHIN NO IPPATSU!
"I see that you've improved, Taiga. I'll look forward to face you again." Graphite said as he flees from Snipe.
"Tch. He ran away..." Taiga said, disappointed that Graphite fled.
The three Riders then untransformed and confronted each other.
"So you two managed to finish off that Bugster?" Taiga asked.
"Just what are you planning?" Hiiro asked.
"I was going to take your Gashats away, but then Graphite appeared..." Taiga answered.
"What do you have against that guy?" Emu asked.
"You don't want to know, expert. All you wanna know is that I'm going after your Gashats." Taiga answered.
"See ya." Taiga said, and he leaves.
"What's with that guy?" Emu asked.
"Who cares. Come on, let's go back to the hospital." Hiiro answered as they ride their motorcycles and went back to the hospital.
"Thank you for saving my son." The mother said.
"No problem. That's what we doctors do after all. To save our patients no matter what." Emu said.
"We're better get going now. Thank you again." The mother said as they are leaving the hospital.
Meanwhile, at Genm Corp., Kuroto Dan, the CEO of Genm Corp. can be seen sitting on his office while holding a Proto Mighty Action X Gashat.
"I'll do whatever it takes to defeat them!" Kuroto ranted as he grips his Gashats hard.
"But before I do that..." Kuroto said as it shows a mysterious Gashat that has yellow energy on his desk and then he grins.
See you next game!
