Note: This is basically my first fanfic, and I intend to grow as a writer as this most likely complicated story continues.

Note 2.0: I wrote the first part of this fic last September, so I hope my writing has improved since then.

[KAMEN RIDE:]

"Henshin."

[DECADE]

Several shadows appeared from the mysterious being and returned to him after the announcement from their belt. A black armor formed around him before pieces of his arms, legs, and helmet became magenta.

Several black lines jumped out of the belt, flying in front of the being for a few seconds before flying into his helmet. Instead of hitting the mask as any other fast blunt force would do, it somehow fused with the mask, leaving a slight barcode-like pattern.

As the transformation started to finish, the lenses on the figures' eyes glowed a menacing green as he stared at his foe.

The foe in front of him was an indiscernible shape to whoever was viewing, but the inhuman sounds this threat was making left an idea.

"Who are you?" The enemy hissed out in a serpentine voice filled with malice.

The figure chuckled as he somehow took a relaxed and tense fighting stance, preparing to dish out a lot of punishment.

"I'm just a passing through Kamen Rider."

With that, the Rider rushed forward at powerful speeds hitting the enemy with even more powerful punches. The enemy was being pushed back, but the hits were only leaving small bruises.

The Rider jumped back before the enemy could retaliate and took out what seemed to be a random plastic card from inside of a small booklet that was on the left of his belt.

The Rider grabbed both sides of his belt before splitting them apart. This action seemed to make the center of the belt flip sideways and leave a small opening for a thin rectangular object.

He flipped over the card before throwing it into the belt, which made the belt call out again.

[ATTACK RIDE:]

Not giving the enemy enough time, he grabbed both handles on the sides and pushed them back together, flipping the center back to normal.

[SLASH]

The small booklet seemed to grow a blade and handle on two corners of its sides, creating a temporary blade.

The Rider ran forward, slashing at the enemy's chest, leaving a slightly bigger injury and pushing it back.

The enemy retaliated with a splatter of poison from its mouth, which the mysterious Rider dodged and ran forward to slash at the enemy again. When the blade reached the enemy again, it seemed to somehow have after images that also caused damage.

The odd creature gasped on the floor in agony, holding his large wound. He looked up at the Rider, snarling in pain and disdain.

"Damn you, Decade!"

"Hmph." The Rider know known as Decade, grunted in disinterest, grabbing another card from the booklet that temporarily turned into a sword.

This new card only seemed to have a large logo in the color gold that looked like Decade's face but in the middle of a smaller barcode.

Unlike before, he did his actions more slowly.

He grabbed both the handles of his belt and separated them again.

He held the card in front of himself and impossibly threw it down into his belt's slot.

[FINAL ATTACK RIDE:]

Since he was going slower this time, his belt had enough time to ring out a sound similar to that of an alarm signaling his next attack. He grabs both sides of the belt again to end this battle.

[D-D-DECADE]

While Decade seemed to be getting ready to jump up in the air, body-sized transparent cards appeared in front of him. When he finally jumped in the air, the cards followed as well.

Decade seemed to stall in the air for a mere second before getting in a kicking position. He aimed downwards towards his enemy, who was looking up in fear as the cards in front of Decade also angled downwards.

Decade kicked through the first card, appearing out of the second one, repeating this action through multiple other cards, and getting a golden glow on his body.

When he reached the final card, his foot landed straight through the enemy, making it cry out in agony as an explosion appeared from its being.

Decade stood up dramatically as he turned toward another figure who was watching the battle with boredom.

This other figure was entirely humanoid and seemed to be darkened out and indiscernible but seemed to be holding some sort of weapon similar to a gun.

"Are you done?"

Decade scoffed and turned around, walking away from the fire left away from the explosion.

"I'll be done when I figure a way out of this mess."

The other figure chuckled and slowly followed after the Rider with a look of pity.

"This journey of yours could very well be your last."

Decade paused in his walk, briefly glancing at the figure before walking forward again with some sort of purpose.

"I won't find out if I don't even try." He said with pure determination oozing out of his masked figure.

The figure looked at him in sadness as he kept following. It's hard to watch someone you've grown to love to walk towards his doom.

Water.

As far as the eye can see.

In the middle of this vast ocean, all you can see is it. But in this vast ocean, we can see an island made of green.

A large forest filled the center of this island with small hills of grass surrounding the island. The ocean submerged every once in a while, rising and falling, leaving a small patch of muddy ground that seemed hard enough to walk through.

In the grassy hills, a noise rang out, startling a few birds and making a few bunnies run away.

A small baby fox peeked its head out of a log that it seemed to have been sleeping in.

It notices a human being layer out on the hill, groaning in discomfort, twisting, and turning.

The human on the ground was wearing pretty loose black jeans with a magenta-colored t-shirt and a black trenchcoat that seemed to reach his knees. The trenchcoat had numerous pockets on its outside that all used buttons to close them up. The human himself was a light-dark-skinned man who was wearing a pair of glasses that somehow hadn't fallen off.

The baby fox noticed the man's general shape and snarled as a rush of haunting memories rushed through its head. It jumped out of the log and rushed towards the young man.

It jumped in the air and opened its jaw. Its mouth landed on the man's hand, and it bit as hard as it could.

The man's eyes jumped open in surprise, and he jumped up in fright.

"YEOWCH! GET IT OFF, GET IT OFF."

~Pov: ?~

I screamed out in fear as I felt something bite my hand. I looked around, looking for something to get it off but noticed I didn't wake up in my room. Which made me even more freaked out as I apprehensively looked at what I assumed was a disgusting insect from the outside.

I was genuinely appalled.

What. In. The. Fuck.

A fox?!

The fox looks small, so I can assume it's young. It looks like it has a few visible bruises on its fur, and it looks pissed at me.

?

As I lost the appalled expression on my face, I couldn't help but notice that its bite only really mildly hurt.

The fox noticed my expression and anger swiftly disappeared into fear. I felt a small amount of pity as an animal I regarded as a predator felt fear from someone like me. I gently grasped the fox with my other hand and took it off as it weakly whimpered.

I set it down, and it ran away with a slight limp. I looked confused at the fox for a second before realizing my situation again.

I woke up on a hill, and in front of me, I saw a forest. Looking behind, I notice… the ocean? Weird.

I don't ever recall there being any forests near me. So how did I get here!?

Did I get pranked? Where did I get these clothes from? Was I kidnapped? Why would kidnappers leave me on a beach though?

I pondered all these questions as I walked around the… beach? I have no idea what to call this since I usually see some sort of sand at beaches. Maybe I was kidnapped in another country?

As a few hours pass of me pondering, I can't help but notice the fact that I've walked into footprints eerily similar to the ones I left behind.

There's no way. I can't be on one.

AM I ON AN ISLAND!?

WHAT THE FUCK!

HOW? WHO? WHY?

I fall to my knees as my situation hits me like a bag of bricks. Am I ever gonna get out of here?

I'm never gonna see my family again, am I? I'm going to die on this island and never get my life back. I notice my mind getting darker thoughts and try to calm myself down.

~In the Forest~

As I calmed myself down and got up, I knew I couldn't let myself rot in a random place like this. I walked to the forest with the hope of food.

I saw a few bushes filled with berries but was wary of eating any that could be poisonous, but thankfully, there were trees with apples. I grabbed one and ate it like a madman. I was oddly really hungry, and this was taking my mind off things.

As I finish up the apples and berries, I start to pay attention to my outfit.

Why pin…?

It's not pink! It's magenta!

Oh yeah! This is magenta.

…

Why did I just focus on if my shirt was magenta or not? Weird. Whatever.

I look at my black jeans and notice I have nothing in my pockets. I noticed the absurd amount of pockets on my trench coat.

I check the pockets on my side and notice something weird on my left side.

?!

What.

What?

Why would I…

Whoever brought me here must have some sort of twisted idea of a joke. I know I have nothing to do with this because I'm way too poor to buy this. I mean, what sort of person lets you alone on an island with a Japanese kid's toy?

It was an odd square pink device with several circles in the middle of it. The outer circle had 19 logos of different types representing different series. The middle one was a white one with a green crystal on top. The last circle and the smallest one were just a transparent screen.

This was the Decadriver.

The Kamen Rider belt of a Kamen Rider Decade.

Kamen Rider was a series that started during the Showa era of Japan. Showa, Heisei, and Reiwa.

Decade came from the Heisei era of Japan and was the tenth rider of that time, hence the name Decade.

The most important part of all that info is that it was an anniversary season. An anniversary season that gave the protagonist the power to turn into every protagonist from his era and later the power to turn into everyone after him and before his era.

Why would I be left with this? Entertainment?

At least my tormenter isn't a complete asshat. Yay.

Well, whatever.

I searched a bit more and found the toy booklet that came with the season.

?

For some odd reason, I couldn't maneuver the book into something else.

The book in the show could turn into the main sword and gun of Decade as its appeal.

Sigh.

I open the book like it's normally meant to be and see all the other Kamen Riders. I take the main Decade card and promptly close the book.

What is with all these things missing? The belt to connect the Decadriver is missing as well. Ah, whatever I've given up on understanding this guy by now.

I place the belt on my leg and grab both sides of the belt.

[!]

Whoa! That shit was way too loud. Why did it sound so clear as well?

I play around with the sound of the handles being pressed apart and together again. I get lost in the sound of it getting giddy at seeing one of these in my lifetime.

Being as forgetful as I am, I place the Driver on an 'imaginary belt' shocked at what happens next. A belt grows from my waist, circling itself connecting to the other side of the Driver.

Huh.

No. Fucking. Way.

This can't be real.

My mouth is wide open as I try to process the fact that the Driver might not be that fake.

I gulp as I grasp the Decade card out of my pocket and look at it.

The card had the text MASKED RIDER DECADE and KAMENRIDE under it with the picture of Decade himself front and center.

I grasp the handle of the Driver apart. The centerpiece twists sideways, leaving an opening for any of the cards to be scanned.

[!]

I grabbed the card and slowly put it in the slot.

[KAMEN RIDE:]

After the announcement, a loud alarm sound rang out around the forest, startling a few animals away. I giddly grasp the handle again and scream out.

"HENSHIN!"

[DECADE]

Nine shadows erupt around me, representing the Riders before Decade fly around me before all merging onto my body, leaving a black bodysuit with a white, outlined and sideways 'T' appearing on my chest.

Barcode-like objects fly out of the belt and hover in front of my face. They fly into it, adding the color magenta to most of my body.

I did it.

I've become the destroyer of all worlds, the man who will forever continue his journey. Kamen Rider… Decade.
