Mists, the surrounding palace is hard to see due to the number of clouds covering unique artifacts lying here in this deep realm. You'd need a very big portable fan with ya, otherwise, this would've been easy for a certain treasure hunter.

"Man... These treasures are worth nothing." A mysterious young man said, putting his cloak's hoodie down revealing brown wavy hair. He whistled. "For a world that has some 'godly' treasure. They have terrible traps easy to escape that even a baby can do it."

This is Daiki Kaito, a treasure hunter set out on a journey to steal every world's treasure from anywhere and anytime because he can also travel through worlds with no trouble, but, he never thought about stumbling upon this world.

Kaito gazed at the lying beaut of a treasure in front of his eyes, noticing the object's unique design different from the rest.

The precious item looks pretty shiny for a card, he saw a very powerful aura surrounding it. At first glance, the blue card looks similar to Kaito's own collection. But he scratched that idea off with a shrug.

After confirming that this is a real valuable treasure, he grins. "Looks like no one's guarding this precious card... Good, I was getting bored walking anyway." He said with a smirk.

Before he could steal the card, he quickly pulled out a revolver and shot something from behind.

Kaito turned around to notice what he shot and sighed. "You think I was stupid enough to ignore you here?" He said rolling his eyes. "Your presence gave it away."

A distorted chuckle came out in response. "I was simply curious on what you were doing here... Now I see why."

The young man took a deep breath, pulling out a red card that had an odd icon from the back.

"Good thing I came prepared," Kaito said. He slid the red barcode card into his customized revolver, opening the pump once so.

KAMEN RIDE!

Kaito aimed his driver into the air and smirked. "Let's see what you got," He said. "HENSHIN!"

DI-END!

After pulling the trigger, different colored images of his rider form appeared. All forming into one blue suit with bar codes set on his helmet.

He is, Kamen Rider Di-End.

"Interesting."

The hollowed room lit up surprising Kaito, he slowly watched everything melt into black slime all except the light blue card.

"What the...?"

Goops of slime dropped into the floor, it started moving faster once more piled on that kept growing until it formed into some sort of monster. Its face created a blue mask to cover the red eyes.

"That's definitely one of Shocker's creations," Kaito said with a groan. "And here I thought I could get away this time!"

He brought up his revolver and slid a different card in.

ATTACK RIDE!

"I wouldn't shoot the mask if I were you." The dark spectator warned.

Kaito didn't listen as he aimed for the center of this creäture, pulling the trigger.

BLAST!

Several bullets hit the target badly, making it crumble. The last shot, however, landed on one of its eyes.

"Heh." He smirked before he saw the shadow erupted. "What?!-"

But the last bullet made the figure growl. Its crimson eyes glaring at Kaito ripped his face mask out, doing so caused the slime to slither everywhere.

Once the show died down, the young man couldn't believe what he was looking at.

Well, somewhat.

"Eh...? Momotaros? Is that you?" He asked. "Nah, you wouldn't look like that at all since I saw your true form before."

Right in from him was a large two horn hulking red Oni wearing some sort of robe while holding a large sword-spear weapon on its right hand.

A thought bubble came out, revealing a much less...scary Red Oni who was shouting at Kaito even though he was facing in front of humans who were trained to fight against Onis.

[Short Flashback]

FINAL FORM RIDE: D-D-DEN-O

"Ore! Sanjou-! ACK!" Before Den-O SF could do his signature pose, Di-end shot his back. Reverting into his imagin form.

PEACH.

"Iteee!" Out came a Red Oni, however, not an intimidating one. He resembles that of Momotaros from a kids show back in Japan. "Oi! What the hell was that for!?"

"Nope, definitely not Momotaros." Kaito lazily shrugged. "You're much taller than he is."

The red Oni raised a small brow, scratching its chin in with a question mark above the head. But its feet stomped on the ground hard, angered.

"Actually, now I can see the resemblance," Kaito said with a smirk. He started spraying bullets on the Oni, but it did nothing as it bounced off from its chest.

"Great," He sighed. "Guess I'll have to resort to Plan B." The young man pulled out two cards from his holder, then sliding each one inside his driver.

KAMEN RIDE: REY! KABUKI!

Kaito aimed in front of him and pulls the trigger, two more different colored images of the names said appeared not before revealing their rider forms.

Frost was gathering around the floor until it formed a humanoid figure, but yet he looked like more like a Yeti due to the fur around his chest as blue Gigantic claws appeared after raising his hands up.

He is known as Kamen Rider Rey.

The slow breeze where petals coming from out of nowhere all circled around when a green Oni posed dramatically, however a few of the horns were red.

Kamen Rider Kabuki. But once he made eye contact on the Red Oni, he clenched his weapon tightly.

Kaito noticed this but he waves it off. "You two can go ahead and fight him, I'm going to see what's his main weakness."

The two riders obeyed his command and proceeded to fight the red Oni.

"Hmmm let's see..."

Di-End then analyzed the patterns of its attack, it was fairly easy due to the big swing attempts. "Ah, so you can tank a lot of the physical attacks... That and my own bullets wouldn't do much on you."

Before he could move from his spot, he noticed Kabuki aggressively slashing through the Oni, noticing the wounds lasting longer than he expected.

"Ah, that makes sense." He said. "Considering that he's half-n-half."

Kaito hummed curiously. "Kabuki, try and go for its arms!"

The red-green warrior nodded as he stayed in his stance, focusing a lot of power into his blade.

"Ongeki Da: Goka Kenran!"

Kabuki then severed two of the red oni's arms with a graceful attack, the monster roared in pain.

Rey dug his claws through the ground, turning the floor towards the Oni into ice. The enemy stumbled away on the floor, not able to move without falling.

Di-End smirked. "Time to finish this."

He took out one last card that would end this battle onto the Di-End driver, pulling the pump out.

FINAL ATTACK RIDE!

The two riders, Rey and Kabuki suddenly stopped walking. After that announcement had started, those two faded into the same cards Di-end used previously to summon them.

Cards were now circling one by one in front of his aim, once the two cards were pulled into it, everything stayed and locked.

"See ya."

DI-END!

Pulling the trigger, a giant beam went through the red Oni as it disappeared into nothing.

"Phew, didn't even break a sweat." He said with a grin. "Now, onto my treasure." Kaito then de-henshin back into his rouge form and saw the glowing card in front of him.

However, as he was going to take the blue card with him, shadow tentacles grabbed his right arm and threw him somewhere else.

"What!?"

"That fight was easily handled, good work!" That same voice as before said. "But, I'm not letting you have this..."

"Here I thought I was done with beating that Oni." Kaito groaned. "Doesn't matter, I'll take it by force!"

More and more shadow tentacles prevented him from transforming back into Di-end. He tried to find where the figure is but wasn't able to due to no light inside this room.

"Ah ah ah." It shook its imaginary finger. "You can't fight me, I'm an entity much more powerful than what you just defeated."

"Hah, is that all you got?" Kaito asked with a smirk. "Every villain says that, but they lose when I show them who they're dealing with!"

"Cocky brat." The red eyeshadow said. "It's time I end this charade and put you somewhere else. In the meantime, I hope you enjoy the private little jail cell I made just for you..."

The young man couldn't breathe as the tightness started getting stronger, the tentacle choking him.

"W-Who are you...!?"

He saw his vision fading away, the tremendous amount of pain rendering him unconscious.

"Me?"

It smirked. "I'm..."

"Someone you don't want to deal with."

Kaito went limp after being dragged inside of the black puddle, the red-eyed shadow's laughter echoed across the palace.

[New York: Manhatten] March 30th, 2016 (Morning)

"Josh! We need you to get some groceries, everyone's going to be busy so I hope to see food in the kitchen. Today's a special day!"

"I will don't worry."

The young man named Josh crossed his arms with a frown. 'It's annoying that nobody does much at home when I'm here every day.' He saw his only friend leaving with her parents, thus making him home alone.

Then again, it's always been like this when he was at a young age.

"Right so I have to do my chores, as it's one of the things I can do besides living here." He said boringly.

Washing the dishes, taking out the trash, cleaning the bathroom, mopping the dirty floors.

He's done so without haste due to these activities being usually every day for him. "Done," He sighed. "I'm heading out right now," Josh said to no one in this house he lives, taking his favorite sweater and shoes.

Once he closed the door from his friend's house, he notices the looks people are giving him.

"...I don't want to deal with anyone today." He said after pulling his hoodie up to cover his face.

Slowly letting the time go by, he finally arrived at his destination.

It was a nearby grocery market he goes to, mostly from the good deals they usually have whenever he comes inside.

"Let's see, what everyone will need is Milk, Food, Vegetables, Fruit, Bread, etc." He listed the ongoing list until he got it stuck in his head. "Right, should hurry before someone I don't want to meet comes up to me later."

Josh nodded his head and took off, getting the food.

"Alright, that will be 256.17. Do you need a ride?" The cashier employee asked nicely.

"No, I should be fine carrying all these on my way. It's not that far." Josh decline politely. "Thank you though."

He started to gather the bags before he used to do the carrying. Josh had a good build but still looked slightly thin, he decided to get a bit stronger so that he can collect everything easily with no help.

Not that he gets help anyway.

"Yooooo Josh!"

"Dammit," Josh cursed under his breath. "Hey Eric, long time no see huh?" He said with a forced smile.

The young man named Eric looked to be shorter than Josh, he has brown high-top hair with faded sides. Usually, he wears some-what bright colored outfits and just a pair of boots.

"Yeah man, it's been awhile." He grinned. "How have you been? Powering through after what happened back when your parents die-?"

Josh cut him off by looking away. "I'm fine. Although I'd rather you don't bring that up right now. It happened in the past and I can't do nothing but move on." He said with a minor shrug. "Don't got nothing to hold in life anymore."

"Wow... Uh... I thought you were still mourning for them?" Eric said worriedly.

"Why would I? I barely knew them as much as I wanted to back then." Josh said. "I don't like it when people pity me for something I couldn't do back when I was just a child."

"Oh..." Eric raised a brow. "Sorry if I touched a button or so."

Josh shook his head, taking a deep breath he still had his fake smile. "It's fine, I'm gonna head back home."

"You mean the one where Cathy lets you live at her place?" He said.

"Yeah."

"Ah alright, hope you come back safely home dude," Eric said. "Don't want you to leave everyone you love."

Josh didn't say anything after Eric left.

He noticed couples having fun with their loved ones, standing still continuing to watch everyone enjoying their life. However, it kept him unfazed with that stoic face of his, giving out a yawn.

"Right, everyone I love." He muttered under his breath. "As if I've known that feeling in my entire life."

(Evening)

He finally arrived back home, well, his friend's home. Opening the door, he spotted a couple of people which are most likely Cath's friends, chilling with her in the living room so he brings up the grocery bags.

"I'm back, got the groceries here so help me out will ya?" Joshua asked nicely.

"Eh...?" Cath whined. "Think you can just do that yourself?"

"After I had to carry them here? I'm already tired as is." He replied.

"But-!"

"Come on, just help him out! We can wait." A friend of hers said. "Shouldn't let him lose his last strength over those heavy bags."

Catherine sighed. "Alright," She said. "Gimme a few of the light one's kay?"

Joshua could only pretend to hold back his frustrated look. "Sure."

One by one, they were putting each food from the bags to their rightful place stored in a fridge and other cabinets.

Joshua goes back to his room ignoring his old friend's calling for him.

"Annoying pieces of shit," He said with much annoyance. "If she could at least help me out with the cooking and everything then I wouldn't be so damn tired."

He felt like he was going to explode, so many reasons to just blow up.

But he can't.

Joshua knows that it wouldn't be right to get mad at her, nonetheless, no reason to get so worked up for. Besides, he doesn't bear any ill-will to Catherine but her family. The only thing he wants is to have a much different life than right now.

He sighed. "Gonna hit the hay for today..."

Jumping on his own bed, Joshua took out his cheap android phone, blue headphones, and two leftover pizza slices that should help his appetite for only a few hours.

"Right, today's her birthday." He said. "Eh, it's been a while since we ever had an actual interaction besides the usual greetings."

It's true, after not being able to go to school due to the death of his two parents, he couldn't exactly attend any no matter what. Catherine's family couldn't help him get an education at all because their worries were prioritizing her first.

So he was only able to learn thanks to the Internet, it took a while to understand many things but at least he was able to catch up sadly he couldn't get a job yet due to his age and it was frustrating, not getting to do anything but housework throughout his whole years living here.

With a sigh, he turned off his phone and the lights so he can finally rest.

"I wish I had a shot for a life all by myself... I just, never been cared for or loved someone else. I don't love this family. I was just some sad kid they had to pick up, someone who didn't want to die in this cruel world." He trailed off before he closed his eyes.

Noises of knocking from his door entered his ears. Josh had to quickly put up a tired smile so he doesn't get questioned if he's mad. When of course, he's pissed that he can't sleep without any of that ruckus coming downstairs.

"Sup...?" He groaned.

"Hey Josh, it's me." When the person opened his door, it was Cathy holding a letter for him. "Found this in the mail, it's for you apparently."

Josh raised a brow. "Who's it from?"

"Dunno, it only says Residential Guest: The Treasure Hunter." She responded. "Maybe it's an invite for you?"

"With a name like that, I doubt it." He said with a hum. "If it's an invite for some random group then probably, let me read it then," Joshua said, once Cathy handed him the letter she left his room. "Let's see what this person wrote..."

The letter revealed a blue card on the back, curious he switched it to see an odd cover. This blue card's cover in the front had a look of a monochrome man with a happy face and a sad face split between.

"I see you've been unfortunate in life, losing it as meaning. Inside in that shell of yours to hide thy true self. You've searched for a new hope only for it to fade away, the longer you close that part of yourself. The chances of being hiding from others will hurt them."

"However, that's already begun. Only yourself that is."

"That's why I have a proposition. If you accept it this offer, then you shall be granted a new life away from the world you live in."

"You will leave this home into another, but, it involves a mission if you accept this offer. This proposition will last until tonight at 12 AM. If you don't, then this letter will make you forget about what happened today."

"Signed by..." Joshua muttered. "Residential Guest: The Treasure Hunter." He scratched his hair nervously.

"I don't get this, about everything," He grimaced. "Are they asking me to leave Catherine's home? I know that this offer of theirs stated that I'll get a new life better than what I have right now..."

"There's that mission requirement that I find really suspicious about..." Josh turned on his phone to see the time.

Noticing the time being 10:00 PM, he only has 2 hours from this letter's apparent ability. He sighs and quietly opens his door to watch Cathy, the friends she made and lastly her parents who brought out the vanilla customized cake celebrating her 14th birthday.

"Happy Birthday Catherine!" Her Dad shouted. "Come on, make a wish!"

Catherine blew the candles, she giggled and saw the presents. "I wish to become a model!" She said.

The young man closed his eyes as he reminisces back when he had parents, he held back a tear. Sadly, he doesn't remember anything that involved a celebration of his own.

He barely remembered his own birth once Catherine's parents mentioned it behind his back. That was the only way Joshua could make out that he turned 16 a few months ago.

No one celebrated his birthday because he wasn't their own, Joshua never was someone important to any.

Clenching the blue card, then the letter tightly on his hand, a few tears were leaking out of his eyes from his stoic face.

"Damn right I'm taking this offer...!"

That one sentence caused the deep blue card to glow brightly. His front door closed itself, before the card covered around that it converted into a blue prison door.

Joshua felt an odd sense of a light aura, a deep melody was playing in his head that felt very soothing. His subconscious forced him to walk towards the door and opened the handle carefully. He saw nothing but an endless wave of dark blue, then everything flashed before his eyes.

He saw something grabbing his very body, pulling him inside the mysterious room, leaving the door shut.

His room that was full of many things were fading away, leaving the room empty as if no one lived here.

[Unknown Dimension] March 31st, 2016 (Unknown Weather)

"Mmmgh..." Joshua woke up to a dark room at first, then he saw something wobbly near him.

He saw a strange figure what looks to be standing down. Standing back up, he saw that this room had a very big theme going on.

Right in front of him was like an interview for people that are put in jail. A caller, and a pitch black window to hide anyone's identity out.

"So, this is how my new life is going to be huh?" He said with a grudge. "Great, guess I'll get some food and start counting down my death."

"Oh pipe down kid, you're not getting anywhere with that attitude."

He noticed the same blurry figure that was on its butt down, then he sat down on a chair at the front of the black window preventing him from seeing his face.

"What happened to you?" Joshua asked. "Looked like you went through something rough and about."

"You don't even know half of it kid." The strange figure groaned. "Whatever, I know who you are but you don't know anything about me."

"Prove it," Joshua said crossing arms.

"Your name is Joshua Perez, just turned 16, lost your Mom and Dad in an accident. You've been living with Catherine Sanchez and her family when you were nearly 5, she just turned 14. You haven't been yourself after those rough times. You've been doing chores, making food, for others all this time. You keep your anger and everything in check with that stoic face of yours to hide the pain inside." He said.

"You have no special someone, not even the 'love' you put out for everyone. You, gave up the meaning of life when you couldn't go to school, get a job, nothing." Kaito said with a bored look.

He glared at the man who was telling him everything he knew, his true self. "That's enough out of that mouth of yours, I don't want a damn reminder of how much a failure I am!"

"Alright alright."

The black window slowly went transparent as it revealed a young man that's a few years or older than Joshua is.

"My name is Daiki Kaito, I'm the one that's going to tell you everything you need to know. Starting with who I am, where you are, then lastly your mission." He said.

"From what you just told me, you steal treasures from different worlds which I didn't believe at first. But then you got ambushed by a shadow entity that choked you until you went unconscious? Next, you were given choices between life and death because you're currently inside a jail designed for thieves like you that's apparently impossible for someone like you?" Joshua said.

"That's just about the basics," Kaito said. "I hate to admit it."

"Question. How did you end up getting someone, well, me? Can't be too coincidental for me to get this offer in the first place." Joshua asked.

"It was all on luck, I had to actually choose an 'Arcana' from this old geezer's fortune cards. Anything I picked, was based on what type of person is. Hell, it might've been someone perfect, unhealthy, old, or young. Anyone can be chosen." Kaito answered.

"And that 'Arcana' was mine, it showed a monochrome two face mask that had a happy expression and a sad one..." He said. "That card represents who I am right now."

"Bingo."

Joshua stared at the man's face. "And how do I set you free? What do I need to do in order to get my new life settled?"

Kaito smirked. "Easy, just get back all the cards I lost from that damn shadow. As for your new life, however..."

"I know one of them is giving up my old life back when I used to live with Catherine and her family." He said. "That could only mean one thing... I need to change my identity?"

"Heh, good thing I have someone who's smart. But, not only are you getting your identity changed, but you're also going to a new country instead," Kaito said.

"What, why?" Joshua asked.

"Because the one you're going to has every card of mine there located," Kaito replied.

"Wouldn't that mean I'd need to learn a new language?" He said. "I barely remember my Spanish, which is a mess on its own."

"No, there's this benefit of helping me out where you'll learn the language in an instant once you arrive in your room in that apartment that's somewhere in the middle of this big city, easier to get by and find for more clues on my cards." The young treasure hunter answered.

"Gotcha, so what else am I missing?" Joshua asked.

Kaito then brought up a paper with an emblem to the side, noticing not so many words on the sheet who tosses a pen to Joshua.

"Sign the contract." He said. "Once you're done writing your name on this, you'll be heading in your new room all just for yourself kid."

Joshua hummed remembering that the same words in this contract were like from the letter he received albeit just him helping Kaito being free.

"Alright, you got yourself a deal. It shouldn't be that hard to find these cards you're talking about."

"Heh, not exactly kid," Kaito smirked. "You'll need the Di-End Driver to help you find 'em, besides that. You're going to figure it out anyway after you start blending in."

He nodded and wrote his name into the contract, Kaito's smirk formed as he took the paper in and snapped his fingers.

Joshua's name and last were changing into his new identity, he raised his head towards the young man. "If I remember correctly, a name in Japanese would usually mean something like any other languages. What's mine going to be?"

Kaito smug look made Josh raised a brow. "You'll see."

The young rider then rolled the contract paper up, putting it into his pocket and took a deep breath.

"Now then, I'll need to be specific on this mission of yours. You already know the basics but, I have to warn you what you're going to be facing..."

[Tokyu, Shibuya Excel Hotel] April 1st, 2016 (Evening)

Joshua was now facing the front door of his new home, his new room. He glanced back at the people walking with a low sigh. "I didn't think he said I'd get transported immediately after he explained what's going to be my new identity."

Slowly taking out his new items from his wallet, one is an I.D., a bank account card, and 100,000 yen so that he can use it for bus fare, food, and many things he'll likely need.

He saw an elevator opened its door, out came a man using a cart that had packages with his fake name on it.

'My stuff...? Guess that makes things easier for myself to live in.'

"Uh, here's your belongings... Mr. Seikatsu?" The delivery man said. "Oh, and a few things were added too at the last minute from some man who said he knows you. Someone, you know?"

"...He's an acquaintance of sorts."

"Alright." The delivery man said with a nod. "Well, it's time I head back to the stations. Nice seeing ya kid."

Joshua waved goodbye at the delivery man who looked back with a smirk.

He fiddled with his keys to open his door and saw the nice clean view inside. It was clean, no dirty rags, dust, or anything that would be unhealthy for having. The young man carries his packages one after another to his room.

He noticed the familiar logo just like the contract he signed on the front cover of the box, opening the package to see a revolver-like weapon holding a few cards with another letter. The contents gave brief explanations of what the functions this driver has in store for him to use.

"So this is what I have to do...?" He muttered. "Damn, and here I thought I wasn't going to an actual school." Joshua looks down and repeats the mission Kaito told him on his head.

"Here's the gist kid; You're going to school, getting all my cards back so I can get out of here, and after you're done with all that, you'll have a great life staying there."

"Otherwise, there will be consequences if you don't do what I say."

'I'm not Joshua Perez anymore...' He looked at one of the mirrors reflecting him, noticing the same appearance he has. The dark blue hair he dyed since he liked the color so much, his blue eyes watching the big city's view.

Noticing the change of clothes once he saw his white hoodie, that along with his black pants and a pair of sneakers that have trails of white stripes.

"Your name is now...!"

"Sora, Seikatsu." He said after watching the sky getting dark.
