Alright! My second story! This one is different from Gamer And Messiah, as well as completely unrelated.

First of all, it has no character-based POV. Instead, it'll switch between the perspectives of the 2 hero groups as needed. Second, this is a reverse of what happens in GnM, with the 4 main Riders going to Gamindustri instead.

Now, timeline clarifications. The Ex-Aid crew is from post Genm VS Lazer, so Kuroto's dead and Kiriya will possibly have Level X. The Neptunia part of it takes place in MK2, after IF and Compa save Nepgear and they escape the Gamindustri Graveyard. And of course, Ex-Aid spoilers inbound.

And finally, I own NOTHING. Kamen Rider is owned by Toei and Shotaro Ishinomori, while HDN is owned by Idea Factory and Compile Heart.

Chapter 1: The World of M's Dreams

The 4 main members of CR, as well as the 2 Bugster Riders, are gathered at the office of Genm Corps' newest - and not evil - CEO, discussing everything that happened. Well, mostly Emu getting explanations from everyone else.

"So, lemme get this straight. Hiro's grilfriend came back as a Bugster only to be married to Lovelica of all people, after which Taiga used the Buggle Driver 2 to become a fully powered version of Cronus, but then Brave came back along and kicked Lovelica's butt, and his girlfriend re-died. Then, after me being attacked by that other Parado, the real Parado tried to make a new Bugster alongside Poppy, but Another Parado intervened and tried to mess everything up, but Parado beat him. And all of that was so that Kuroto could make a ridiculously overpowered version of Maximum Mighty X, which also allows him to make extra games, one of which made an infestation of cyber zombies. However, you then stepped up and eventually beat him through a Level X form achieved through Cronus' own Buggle Driver 2. Was that all right, Kiriya?"

"Yeah, sounds about right, Emu." Kiriya states. "Though you forgot to mention that I'm human again. Which I'm a little conflicted about, because while being atleast somewhat normal is good, my time as a Bugster was possibly the best time of my life. Too bad Kuroto and Masamune ruined it." He said the italics under his breath.

"Anyway, why are we here?" Hiro asked.

"It's because the new CEO of Genm Corporation had made a deal with 2 other companies to port one of their games to their system."

"What are the companies, Taiga?" Emu asked.

"I think it was Idea Factory and Compile Heart... Don't quote me on that though." Taiga answered.

"Wait. Are you telling me they're porting a freaking Neptunia game? Which one?"

"Don't ask me."

"I hope it's V2. I'm still salty about that happening."

Parado looks at Emu. "Well, since we're technically the same person, the salt is shared."

"Well there's a benefit to you being around..."

"Hey, Emu, that was kinda mean!"

"Sorry, Parado!"

Suddenly, the door opens, revealing the newest CPU of Genm Corp. "Oh, I see the Riders are all here. Good! Now we can start!"

Emu immediately jumps into the conversation. "Which game."

"Uh... what?"

"I know that the game you're porting is a Neptunia game. So please tell me: Which one is it?"

"You got me! True, it is a Neptunia game. Specifically, Hyperdimension Neptunia MK2!" He pulls out the game's Gashat. Which isn't technically meant to be a Rider type of one, but...

"Isn't it dangerous to use Gashats as cartridges anymore?" Hiro asks. "Genm Corp's luck with keeping their Gashat-based games Bugster-free was absolutely terrible."

"Don't worry. I personally tested it and nope! Not a single trace of the Bugster Virus!"

However, Emu is sulking a bit. "Why isn't it V2..."

"Whatever. I want you, Emu Hojo, AKA Genius Gamer M, to try this game out."

And his mood is immediately brightened. "Let's do this."

They sit down next to the Genm Re:Play (which is what I'm gonna call Genm Corp's console) in the office, with Emu holding the Gashat... and accidentally pressing the button that, if this were a Rider Gashat, would've activated it. Immediately, Bugster particles start emmiting from it, and Emu throws it away, but it just... stays in mid-air.

"You said this game was Bugster-free!"

The CEO has a confused look on his face. "I was sure it was! Must've gotten infected afterwards..."

Suddenly, the Bugster particles vanished, replaced by the Gashat doing its best impression of the first part of the original HDN's opening. White triangles spazzing out around it and everything.

"What's going on?" Emu was equal parts scared and confused. This is something he has never encountered before in his entire career. And he dealt with 2 versions of the same madman trying to make a parallel Earth sandwich!

"I have zero clue!" Taiga replied. "This is definitely a first for me!"

The CEO and the Bugsters all backed off, but the Gamer Riders were trapped in the resulting black and white field, which then collapsed in on itself, leaving only the Gashat behind.

"What was that?" Parado asks no one in particular in pure, unfiltered confusion.

Meanwhile, in Gamindustri...

Nepgear just recently woke up after her scuffle with CFW Judge. Well, scuffle isn't a good term. It was more of a one-sided slaughter in Judge's favor. Anyway, she just recently got a mission from Histoire. It involved gathering the Mascots of each nation and getting the help of the other CPU candidates, as per normal, but...

"There's one last request I have for you."

Compa, Nepgear's nurse friend by proxy of her being friends with her sister, Neptune, immediately responds. "What is it, Histy?"

Histoire makes a sort of magical holo-screen behind her. It showed multiple photos of oddly colored shooting stars in each nation.

"Whoa, now that's pretty cool." IF, another of Nepgear's friends by proxy, stated. "But what is it about? Just looks like normal pictures to me."

"I thought so too, but their colors are very weird. Shooting stars are usually just white. And even with that aside, I get a feeling that it would be a bad idea to now find out more. So, I wanted to ask you to investigate on the way."

Nepgear immediately responded. "Sure, Histoire! We'll remember to do that!"

"Alright. So, to recap your 3 missions. 1) find the Mascot Disks of each of the nations. 2) get the helping hands of the other CPU candidates. And finally, 3) find out the mystery of these shooting stars."

"Alright, we got it. Let's go, Gear." IF says and leads the way out.

"Yeah! Don't fall behind too much, Ge-Ge!" Compa follows IF in both ways, that classic smile all over her face.

"This isn't a race!" She immediately goes after them, as their adventure begins.

Alright. So, here's the first chapter of THIS fanfic... Really hope it doesn't suck. So, yeah, through a mysterious Gashat malfunction, the Riders literally fall into Gamindustri (Yes, they're the shooting stars). Don't ask me how it makes sense, I don't know myself. Anyway, Imma end it here. See ya in the next chapter, Mystery of the Kamen Rider!
