Author's Notes: It's been a while since I wrote my first Kamen Rider story. And since Kamen Rider Ex-Aid is finally ending that it ended up becoming my 3rd most favorite Heisei Rider shows in my list (my Top 1 is Gaim), I decided to make another Kamen Rider crossover fic... this time with Danganronpa. And for the main character of this story, it involves more with a so-called 'Ultimate Gamer'. If I were you guys, just read the story. Moreover, this is a prologue. So enjoy reading!

I don't own Kamen Rider or Danganronpa.


Prologue: Game Over?

Blood.

The girl is leaving a trail of pink blood as she tries to head to the exit door, which the words inscribed as 'GOAL'. She endured a lot of dangerous traps inside this
cold and dark dungeon maze.

However, one Chiaki Nanami vowed that she would never bow down to someone maniacal girl named Junko Enoshima. The latter put her into this deathly maze which she calls it an 'execution' for the Ultimate Gamer. Of course, the light pink-haired girl had no choice had to go through the death maze for one goal: to save her own classmates, the Class 77-B of Hope's Peak Academy. She knew that the whole Class 77-B, her classmates and friends, are in danger and as class representative, it's her responsibility to reach out and help them.

Indeed, she is. Chiaki herself is a girl who loves to play video games yet she is special since she's the heart of their class. For someone like her, this could also be an achievement. But in their current situation right now, Chiaki had no choice but to go through this sick, twisted game.

When she finally reached the door, she took a hold on the doorknob. However, the exhausted, tired wounded girl's body became static. Chiaki cringed a bit caused by her own stress. She shook her head, shrugging off the stress and decided to go on. She opened the door and saw illusions of her own classmates and even Chisa Yukizome, their homeroom teacher.

"Welcome home, Nanami…" an illusion of Chisa said as the latter offered her hand.

"Everyone…I." she mumbled.

Then everything went black, and all that is left is a painful scream.


(2 years later, during 'The Tragedy')

Crimson skies, rubble, debris, death and destruction; this is all that is left. Since the Tragedy of Hope's Peak Academy, this is what the world looks like – full of dread and despair. Murders, riots and war are everywhere. Every living human being on this planet is bound to destroy each other for the sake of despair. Junko Enoshima herself is behind all this, along with the feared Remnants of Despair, which composed of Class 77-B.

In the outskirts of the destroyed city, a young boy in 15 years of age, brown hair and black colored eyes, ran as far as he can. He wears casual attire with pants, shoes, and a navy blue polo shirt. On the look of his face, the boy shows signs of fear and panic.

What causes the boy to run away is there are a group of people chasing him. All of them are wearing masks of a monochrome bear, their eyes glow a terrifying crimson. These people are carrying some weapons like steels pipes, baseball bats and some 4x4 wood. Actually, those masked men are brainwashed due to the monochrome masks they wore, signifying that they have fallen into despair. So they kill people just for the sake of it.

The young boy kept on running trying to get away from those despair-ridden murderers until the former reached a dead end. As he found himself trapped in a corner, he turned to the men who chased him, trembling in fear. The masked men are preparing their weapons, with killing intent.

The first one, tried to come closer in order to kill the poor boy. However, he and his fellow masked men stopped as they felt pain from their chests. Then something engulfs the masked men all of a sudden, as if they were taken over by virus-like entity, transforming them into orange-like monsters. That made the boy scared even more.

As one of the masked men-turned-into-monsters make the first move as he approached the boy-

STAGE SELECT!

The whole landscape changed.

The crimson skies turned into a cloudy sky blue. There are no destroyed buildings everywhere but it's just a plain field with blocks and some large coins, more like power-ups in a video game.

"H-huh? What is this!? Where am I?" the boy muttered.

Suddenly, the boy heard an unusual noise and it's approaching them. Both the young boy and the orange-colored monsters looked on their right…

It was a motorcycle, with an armored rider coming to their direction. While closing on the monsters, the rider jumped and rammed on the monsters, hitting them and knocking them down.

The rider skids its own bike as it makes a stop. The motorcycle is colored yellow and black, and by description, it's a racing dirt bike with a non-sentient front.

Then the Rider itself got off from its bike as it walked towards the three orange-colored monsters. The boy, however, turned to his left as he saw the full glimpse of this mysterious rider.

The suit of the mysterious Rider is pink with black accents; its chestplate had 4 colored buttons similar to a D-PAD on the left and a life gauge on the right; at the bottom of it comes the two weapon symbols, a hammer and a sword respectively. The Rider wears an odd green belt with the lever is located on the left side, whereas it was 'opened'. On the top of the belt is a device inserted on it, resembling a video-game cartridge. Aside from the spiky upward hair on the front of the Rider's helmet, the eyes on its visor are what resemble a platform video-game style.

The said armored Rider maintained a calm composure as it eyes set on its enemies

GASHACON BREAKER!

Coming out from the Rider's right hand is none other than a hammer. The hammer-like weapon the Rider wields had 2 buttons labelled A & B. From the hammer's back is a cartridge slot.

As the monsters began to charge at the Rider, the Rider itself never hesitated to take out the cartridge from the green driver. The Rider blew it and inserts the cartridge to the hammer-like weapon.

GASHAT! KIMEWAZA!

As the weapon charged with energy, the Rider prepares itself against the incoming monsters while holding the weapon's grip.

MIGHTY CRITICAL FINISH!

The Rider jumped high, its hammer-like weapon raised up. The monsters looked up while the Rider goes for the killing blow: the monsters were hit by a powerful smash from the Rider's weapon as they exploded. The boy covered his eyes to shield himself. When he opened his eyes, he saw the masked men passed out, their masks broken… with the armoured Rider left standing.

The Rider approached the young boy, who had mixed emotions of fear, shock, and relief. The pink platform-themed Rider offered its hand.

"Everything's ok, kid. You all right?" the Rider said… in a female voice.

The boy was surprised that the Rider is a girl. However, he answered while reaching his hand into hers, "I-I'm fine. Thanks, um, Miss."

The female armored Rider helped to pick the boy up. The whole area returned to its original, destructive state.

"W-what happened…?" the boy wondered as he looked to his surroundings. "This place is-"

"Yes", she affirmed. "We're back in the real world."

"Real… world…" the boy muttered.

The Rider told the boy while holding his shoulders, "Alright, let's get you out of here. It's really dangerous to roam around, since the whole world fell into chaos and despair. But don't worry, as long as you live, you're gonna be okay."

The boy nodded while the Rider itself took a device similar to a cartridge.

"Here." she gave the cartridge-like device to the little boy. It was colored in navy blue and it bears the initials "C.R."

"Um, what's this?" the boy asked.

"When you pressed that button on that device, you'll be teleported to safety. No, you're gonna be fine. Through that Gashat, you'll be transported to the hospital." the Rider girl explained.

"H-Hospital? But I don't see any hospital here… that's because… everything is gone…" the boy muttered sadly.

Furthermore, the Rider tried to cheer him up. "You know, even the world has gone mad right now… you better not to lose hope. There's still an end to this. Just… don't give up." she concluded while clasping the boy's shoulder.

"Okay. Thanks, miss!" the boy said. After this, he pressed the button of the cartridge as he disappears in front of the Rider.

She sighed in relief while looking back at the downed despair-ridden masked men. As she walked away towards her dirt bike, she heard a ring tone and took out her communicator, resembling a stethoscope.

"Extraction confirmed. We will take care of the kid." said the voice that came out from the communicator, which is a male.

"Thank goodness." she said in relief.

"So you'll be on your own now, huh?"

"Just the opposite, actually. I still have some work to do before going back our… secret lair." she replied with a chuckle.

"Heheh, alright, alright; everybody knows that this is your new home. Just be careful, okay? You're more than just an 'Ultimate Gamer' now; you're job is to save people and fight the Bugsters… even the new strain itself."

"I know… a lot of things happened during those six months. And… it's not just a job for me. It's more of a promise… and my mission." she affirmed.

"I see… well, you're not just a former Ultimate student from destroyed Hope's Peak Academy. You're now a Kamen Rider..."

"Yeah, thanks for the heads up." the girl ended the call as she hopped on her bike, revved it up, and rides away from the area.


(At the top of a secluded building in Tokyo)

It's been two years since the Tragedy. Yes, the world is falling into despair. But for me, this is more like a nightmare turning into reality.

I stood up at the top of the building, while overlooking the whole city. Well, to put it, this was once a city. Now, a desolate place filled with despair. Sometimes, I want to wake up from this nightmare and nothing happened.

But here we are… and because of what happened to me, my friends have brought this world into ruin. In fact, they were brainwashed by that woman. It's not their fault. My supposed 'death' brought them to the depths of despair… but they didn't know…

That I'm… still alive, currently fighting an unknown enemy and saving people as much as I can, while trying to find a way to save my friends.

I undid my transformation by taking out my own Gashat, reverting back to my normal form. And if you wanna ask, I'm wearing more of a casual outfit. I still have my Gala Omega pin in my hair. As I looked down, I muttered…

"Hang in there, guys. I'll do my best to save you. I will change everyone's fates and bring back hope in this world… even I'm fighting alone."

I turned back and began to walk away, to continue my work. I ask for one more game, one more round… but I never expected that something would grant my wish… and here I am. As I keep on walking, I disappear into nothingness.

My name is Chiaki Nanami… and I'm not just an Ultimate Gamer, I'm Kamen Rider… Ex-Aid.


Author's Notes: And... this concludes the prologue. Anyhow, shoutout to Mask Rider Roy for doing a Chiaki-centric story with her as the main Rider. However, this is more like both an AU and IF, dealing about Chiaki being alive and what makes her being the main Rider. Oh yes, I'm gonna include Brave, Snipe, Lazer, Genm, and Para-DX on this one... while planning to include OC Riders here as well. I'm also planning to include Kamen Rider Fuma in the story as well. I have no idea when I'm gonna update this, but I'll do my best.

You know the drill: read and review and I'll see you guys later. And remember - Life is Beautiful.
