A war was breaking out in a desolate wasteland where various armies were charging towards a man in gold armor in front of a large stone statues placed in the ruins of a city with a large statue that had a cloaked man posing with a plaque on the bottom of the statue, with the name part broken off, leaving behind…

COMMEMORATING THE BIRTH OF OUR KING

Circling past the man were statues of past Kamen Riders as a man in golden armor smiled before starring right at the armies with a smile on his face.

"Attack!" an aged warrior with grey hair shouted as thousands of gunshots began filling through the air before hitting a barrier several feet from the armored man while several mecha began to trudge towards him.

He shook his head as he lifted his hand, somehow catching the mecha's fist before flinging it right at another mecha before waving his arm, causing the projectiles to be redirected at the attackers, killing them. With his right hand, he stopped all of time itself.

"Ha! Do you possibly think you can defeat me?" he questioned before laughing for a bit, "You can do no such thing! You know why?" He then brought his hand to his chest to cause a burst of energy to disintegrate nearly everything in his path.

"Because no matter what you can do, your fate has already been written in the annals of history!"

"Gah!" he cried out, jolting out from his bed. A boy with red eyes and jet black hair that had gray frosted tips had just woken up from what seemed to be a nightmare. The boy began to look around; he saw that he was in a normal Western looking bedroom with a few posters for different movies, a desk where a worn-out book stood, and a desk lamp and alarm clock by his bedside.

"Ugh, it was that dream again…" he sighed, before going to pick up the strangest object on his bedside, a black pocketwatch-like object that had no dial and exposed cogs and wheels at the front. 'Why am I having these dreams?' he thought to himself.

"Rex? Are you awake?" a voice from downstairs called out to him.

"Yeah, I'll be up in a minute!" he shouted, before getting up.

He went to the bathroom to wash up and to prepare for school. As he looked into the mirror, he began to think back on the dream he had. "Your fate has already been written in the annals of history…" he muttered to himself, echoing the words of the golden armored man, "What does he even mean by that?"

CHAPTER 1: RIDER TIME 2018

As he put on his school uniform, a long white shirt underneath a blue jacket, red tie, grayish blue colored pants, and black dress shoes, he grabbed an apple juice box from the fridge and began slurping it up pretty quickly. He soon ran to the door to find a young woman with long purple hair and wearing a female version of the school uniform he was wearing, apart from a long navy blue plaid skirt waiting for him.

"Hey Henrietta!" he greeted.

"Took you long enough Rex…" she noted in a kind manner. She was Rex's friend for a while now, always checking up on him ever since he lost his parents back in 2009, forcing him to live on his own for so long.

"So, did you finish your homework for History class?" she asked him as they began to walk through a walkway, Rex in particular as he brought his bicycle up a hill.

"Barely…" the young boy sighed, causing Hernietta to notice the large bags under his eyes.

"Let me guess, it was 'that' dream again…" she guessed, knowing what the answer was as he nodded and took out the watch from his pocket.

"Sadly… and it's always the same one too. There was a war against all these soldiers against this one man, and they would always lose" Rex recounted, "I don't even know why that comes to mind, but after I found this thing months ago, it's always this one dream…"

As they continued on their way to school, Henrietta decided to ask him about something. "Hey, did you really put 'king' as your desired career path?" she asked her friend, "You know in this day and age it's kind of…impossible, right?"

Rex, having heard this question many times in the past, sighed as he answered "I know that it sounds ridiculous but I just have a feeling that I will become one, okay?"

"How so?" the young girl asked once more, still not convinced by his words. "Well, I don't really know…I just…I feel like my heart is telling me that becoming the king is my future, my destiny if you will" he replied in the best way that he could.

Unbeknownst by the pair however, a man with dark green eyes, and wore a steam punk jacket, a large ten-gallon hat, was watching them from afar. He began to look at an old book as he smiled.

"It's time…" he muttered to himself as he closed the book, "It's time for the war to begin…it's time to awaken, the King of Time…"

The day went by pretty fast for the two and Rex was peddling home when he noticed the man standing in his way. "Uhh… can I help you sir?" he asked in confusion as he got off the bike.

"Perhaps…" he noted as he examined the boy, "Maybe you might be…the one…"

"The one? I'm sorry but I have no idea on what you mean by that…" Rex replied as he began to back away, accidentally hitting a bump and causing the watch in his pocket to fall out. The man then picked it up before tossing it back to Rex.

"Keep a better hold on that thing, it might just save your life…" he noted, "Just remember…"

The future is whatever you want to make it. The question is thought, what future do you want to make?

Still confused, Rex put the watch right back into his pocket and walked away, not even bothering to take another glance at him.

'Man, was he creepy…' he thought to himself. As he stopped for a moment, he decided to turn around and see if the strange man was still there. But when the boy looked back, he was gone, vanished.

"What the?!" the boy gasped as he went back to examine where he had met the man. He began to think about what had happened and simply shrugged his shoulders and continued on his way home.

'Maybe I'm just tired…' he told himself as he shook off what had just happened.

With his home nearby, he prepared to walk on by with no problems before his head began to ache, causing him to see various images to flash in his head, images of masked warriors and dark monsters. As the headache subsided, Rex began to think to himself.

'What's going on?' he asked himself mentally, 'First the dreams, then that strange cosplayer, and now this...'

That's when he heard a stomping noise come from behind him. Confused, the boy turned around and was greeted by the sight of a giant red robot with black arms and feet, strange lettering on the chest, and a large stopwatch-like head.

"What the hell?!" Rex cried out as he began to back away.

"I finally found you…Oma Zi-O…" the robot growled.

Terrified, Rex got back on his bike and began to pedal past his house and try to run for his life. As the boy tried his best to get away from the mecha, it wasn't deterred as it shifted into a more hovercraft-like mode which allowed it to chase after him with ease.

"Oh come on!" he shouted in frustration as he looked back.

After several minutes of being chased like a cat hunting down a mouse, Rex spotted a roofed walkway where Henrietta was walking by and peddled straight for it. As he stopped to catch his breath, Henrietta was concerned as she watched him tired after using much of his energy to escape the robot.

"Rex, are you okay?" she greeted him, unaware of what he went through, "You look like you went through a marathon…"

"You could say that" he noted as he spotted the red robot fly right towards the opening.

"Ha! Can't catch me now!" he taunted, a big grin grew on his face as he thought that he outsmarted the machine. Unfortunately for him, the robot flew upwards towards a window on the roof, causing the boy's face to begin to pale in fear.

"Thought you got away so easily?" the robot snapped back as it transformed back into it's humanoid mode and slammed its fist into the window, knocking the two away.

"What the hell?!" she cried out, "Rex? What's going on here?!"

"Does it look like I know?" he spouted in an exasperated tone.

Pretty soon, the two began to run for their lives as the red robot continued to use each and every window to try and smash the boy, who was at the same time trying his best to protect his friend from getting caught in the crossfire. When the two thought that the coast was clear, the robot soon flew in and landed in front of their only escape route.

'What do we do now?' Rex thought to himself, 'We're trapped!'

However, before the mecha could get it's hand on the boy, another machine similar to the machine apart from it's silver and pink color scheme arrived and rammed into the robot.

TIME MAZINE!

"Oh great, not another one…" Henrietta whined as they prepared to run from yet another killer robot, only for the chest to open and reveal a young woman with long white hair cut in a princess hairstyle, a small cream white cloak paired with a frilly white dress, a pair of grey gloves, and grey hiking boots with black soles reaching out to the two.

"If you two have any wishes to live, I suggest you come with me!" she told them.

"Uh, should we follow her?" Henrietta asked the young boy, who was looking at the robot recovering from that attack.

"Not like we have a choice!" he shouted as they followed the girl into the robot, where they spotted a control mechanism that the girl used to pilot the robot.

"What the heck?" Rex asked, "Since when did my life become a mecha anime? And on that note, who the heck are you?!"

"Less talking, more escaping…" she told the boy as she brought up a holographic interface which displayed the year 2018 before spinning it. "Initiating chronological displacement system!" she shouted as a large hexagonal portal appeared in the sky for the machine to jump into.

After the machine exited the portal, the two saw that they were now in Edo Japan, specifically the year 1671. "Whew, we're safe…" the girl in white sighed as everyone was still on edge on being attacked just seconds ago.

"Is everyone alright?" she asked as they nodded, Henrietta holding onto one of the seats of the machine while Rex was struggling to stand before his strength finally gave out and he sprawled onto the floor.

Not amused by the boy's reaction, the girl in white soon walked over to him and reached out her hand to the exhausted Rex, "Huh, you two seems pretty worn out…what exactly happened?" she asked Henrietta.

"Who...who are you?" the young girl inquired, ignoring the girl's initial question. With a sigh, she helped Rex back on his feet and onto the other seat and prepared a screen.

"Before you guys start asking questions, you might want to see this…" From there, a video began to play which depicted a battle between several people and a golden warrior, something that Rex definitely recognized.

"T-that's-…" Rex gasped, "How is this-?"

"Is that…is that the dream you've been having for months now?" Henrietta asked him, seeing that the boy recognized this video somehow.

"Let me explain, my name is Weiss Tsukuyomi" the girl introduced herself, "I'm a resistance fighter from the year 2068. I originally came to your time to try and find the one who would become that man you saw in that video."

"Who? Me?" he asked. "It's possible…" Weiss stated, "For years now, Oma Zi-O's identity has been lost to time, so we decided to find someone who had the same desire as the demon king since by this time, he would be the same age as him."

The girl soon got up, "Come on, we better explore this time period…" With not that many options, the group decided to exit the machine and walk through the town. The trio soon reached a small shop and stopped by in order to have a snack.

"I would like three cups of tea for me and my traveling companions please?" she asked the shopkeeper, who nodded and left to give them what she ordered. After taking out a large tablet, she brought up some Japanese yen which slipped from the tablet onto the table.

"Woah, that's pretty cool…" Rex said in amazement. "So, what exactly does Rex have to do with this demon king?" Henrietta asked Weiss.

"Well, it's because he's a Singularity Point" Weiss explained, "You see, Singularity Points are people who exist outside of time, thus being unaffected to the changes in the time stream."

She soon began to explain her current situation, "Back in my time, we deduced that the demon king, Oma Zi-O, is a Singularity Point himself and with his knowledge of the original timeline, caused an event known as the Edge of Time; in which the whole of the Heisei Era of Kamen Riders were wiped from the pages of history."

"Wait Kamen Riders?" Rex asked in disbelief, "You mean those urban legends are real?"

"Oh yeah, they are more real than you think…" Weiss affirmed, "In fact, there's a story floating around the base about the Heisei Riders specifically. They say that there was a Rider who had dominion over time much like Den-O, but he fell to the darkness and became the demon king…"

"So you're saying that I might be this mystery Kamen Rider?" the young boy asked before taking out the black watch, "Man, my life has been crazy ever since I found this…"

"Wait, is that a Ridewatch?" the girl in white gasped, taking the device much to Rex's chagrin. "How did you get this device?" she asked him, but before he could answer her with a question about that term…

"Hey, who do you think you are?!"

…a voice shouted as the trio saw two Japanese men in a brawl over some unknown dispute.

"Don't you dare disrespect an Edo craftsman, you bastard!" the man shouted as a bald man, likely his opponent, was helped up by two other people. "What the heck's going on?" Rex asked as the three walked towards the fight, but was blocked by the crowd.

"Excuse me, but I need to test something." Weiss stated as she hid behind her and shouted "Hey, why don't you try and pick a fight with someone your own size!" The crowd soon dispersed as Weiss and Henrietta blended into the crowd, leaving Rex on his lonesome as he was pushed towards the two craftsmen.

"Who the hell are you supposed to be?" the bald man asked the young boy. "Uhh…" he mumbled before putting on a brave facade, "I'd like to ask you both to stop this fight right now. Take your arguments elsewhere!"

The two men then laughed as the men who helped the bald craftsman began to approach the boy. Immediately Rex saw this and began to back away, "Hey guys, can we please talk about this?" he pleaded before accidentally stepping on one of the craftsman's feet, causing him to cry out in pain and causing a fight to break out between the group.

Immediately, Rex began to fight against the five craftsmen, using his limited knowledge of martial arts to gain an advantage over the five. As he dodged one man's punch, he landed a high kick on the head of another craftsman, dazing him long enough for him to land a judo throw that knocked him onto the ground.

As the battlefield changed from a circle of onlookers to the bridge, another craftsman tried to grab Rex from behind, only to receive a backhand punch before the boy threw them off the bridge and into the river below. Afterwards a craftsman was able to put his arm behind his back, only for Rex to stomp on his foot and land an uppercut that sent him to the floor.

The bald craftsman, angry that this Yankee was practically toying with them, grabbed a paddle and tried to crack it on the boy's skull. Rex, seeing this coming, quickly jumped off of one of the downed men to land a Superman punch on the man, knocking him into the drink as well. Once he saw that he was safe, Rex soon dusted himself off as he began to catch his breath and looked at the three groaning men on the ground, and the two craftsmen swimming in the river.

"Gah! You'll pay for this!" the bald craftsman growled as he angrily shook his fist at the boy, who merely shrugs before walking towards the two girls.

"So what exactly was that for anyway?" Henrietta asked Weiss.

"I wanted to test Rex's combat prowess and see how well he fights" the resistance fighter answered, "And it looks like he did pretty well…"

"Well your method was pretty…strange…" Rex noted as he stretched for a bit, right before they heard screams erupt from the crowd behind them.

From out of the people, an armored figure walked forward towards the three. He was in a red bodysuit with grey shoulder pads that had pointed crimson red tips, a rounded chest plate that included a 'watch strap' that went down the middle of the suit in the front and back, two black objects strapped to his forearms which had devices similar to the watch Rex had, black gloves with yellow tips. His boots were crimson red with black knee pads, silver anklets, and black tips. Finally his helmet was black with white on the face, a symbol of a yellow clock behind a black circle, and large yellow hiragana letters as eyes.

Finally, around his waist was a silver belt that had as its centerpiece, a white watch-like device along with an LED screen in the center displaying in yellow the year 2068, a molded in button on the top, and two slots which had a black watch with a red dial and the very same helmet as the man on it.

"Who the heck is that?" Rex asked, seeing the similarities between this armored man and the red robot that attacked them earlier.

"That's Kamen Rider Geiz. He's a man who's here to kill whoever Oma Zi-O is!" Weiss cried out.

"So since I'm the only one who is a known Singularity Point means-" Rex said, realizing what that meant as Henrietta grabbed the boy by the back of of the collar.

"That means we need to get out of here!" the girl shouted before they made a break for their own time machine.

Pretty soon, they made their escape as they entered the portal and tried to escape.

"Whew, we're safe…" Henrietta sighed. However their moment of calm was interrupted when the vehicle shook violently, sending everyone into a panic.

"Just our luck…" Weiss groaned as she realized that Geiz was still after them.

As they tried to maneuver away out of the way of Geiz's assault, one well-placed shot sends them into a different timeline, causing them to crash into a glowing red wall before crashing into a nearby construction area.

"Everyone hold on!" Weiss told Henrietta and Rex before impact, where they were all flung out of the machine with Rex in particular being flung straight into a nearby pillar before cracking his head on a pillar, knocking him out.

Elsewhere, a person was investigating the area. He was a young man with a pretty athletic build with light brown hair and hazel eyes. He ore a blue and white jacket with a dragon on it over a black shirt which had some text, a red flannel shirt tied around his waist, charcoal grey pants, and boots.

heard the sound of a crash earlier and decided to see just what happened. 'Maybe it's a Smash attack…' he thought to himself as he examined the damaged, yet very mysterious, vehicle. That's when he spotted Rex's prone body along with a very injured Weiss holding an unconscious Henrietta and quickly pulled out a strange smartphone to dial up someone.

"Hey Sento, get over here fast!" he said on the phone, "We have some survivors!" He quickly went to help Weiss as they laid the girl onto the ground.

"Are you guys okay?" he asked as got the boy from where he crashed and checked his pulse.

"I'm fine, barely…" the girl in white answered before she tried to get up and winced at the pain, "I'm just worried about them than me."

"Are they friends of yours?" the young man inquired, to which she thought about it for a moment and responded with "Kind of…we're more of acquaintances than friends…"

"Well we better get him back to our place before he goes belly up..." Banjou noted before he helped get the two injured teenagers get some medical attention.

The boy awoke, disoriented but still alive. As he looked at his surroundings, he found himself on a large pink stain glass platform, adorned with various symbols along with an armored warrior in the center, resting on a large throne.

'Where...am I?' he thought to himself, only to stop as he had somehow heard his thoughts.

As Rex began to wander through this platform, a large mirror materialized before him, showcasing his reflection, albeit he wore very different. It was a black hooded jacket with gray sleeves with light gray insides, a white shirt that had a picture of a clock with the hands pointing at 1 o'clock and 11 o'clock, a pair of brown military tactical finger-less gloves, a Watch Holder similar to the one Geiz had on his right arm, a pair of dark green hiking boots, and a pair of black and white sports sneakers.

Come forth...young one...

"Ooookaay..." he pondered as he looked around the area. 'Great, now I'm starting to hear voices in my head...'

As he approached the mirror, the boy reached out his hand towards his reflection, before causing a ripple effect to appear before him. All of a sudden, a bright light emitted from the glass, causing the boy to stumble forward. When he regained his sight, he saw that he was in the very same attire, and his school uniform was now being worn by the reflection.

"What the heck?" he asked to himself as the mirror dissipated before thousands more appeared each depicting various moments in time.

"What is this?" he pondered as three mirrors appeared before him, all showcasing a small glimpse before freezing in place. "The heck is going on here?" he asked aloud, hoping to get an answer from someone.

What is it you desire?

"What do I desire?" he asked the voice, confused about what it meant. As the boy looked around cautiously, he began to walk towards the leftmost mirror, depicting three video game-themed figures standing tall against a black and green armored warrior. The pink figure then leaped onto a yellow bike and prepared his hammer while the other two prepared their weapons, which were a sword and gun respectively.

"I'll clear this with no continues!" the pink figure declared as the scene stopped as Rex heard the voice once more.

Balance...

A body and mind if equal merit and equal potential.

Is this what you desire?

This confused Rex further as he backed away from the mirror and went instead towards the middle mirror. The mirror then began to replay a scene where an orange-themed samurai took out an orange mechanical padlock and opened it.

KACHIDOKI!

Immediately, he removed the padlock on his belt and replaced it with the mechanical lock before placing his hand on the plastic 'knife' to 'cut open the lock. From a strange zipper came a large metal orb which unfolded into a suit of armor that formed around the samurai.

SOIYA! KACHIDOKI ARMS! IZA SHUTSUJIN! EI EI OH!

Once he landed, he stood tall against an army of flying pine cone-themed soldiers before the scene stopped.

Vitality...

A rugged body that will endure even the toughest of challenges.

Is this what you desire?

Once more the boy backed way as he turned towards the last mirror he had not seen. This mirror had the shortest scene to showcase as a detective in black alongside a young woman were staring at a young man in green standing below them.

"Phillip..." he asked the man, "I want you to access the Planet's Bookcase."

The young man complied as Rex watched him stand in the middle of a docking bay before raising his arm and causing the area around the man to fade to white before thousands and thousands of bookshelves appeared around him.

Wisdom...

A sharp mind that will grant mastery of wondrous power.

Is this what you desire?

After backing away from the last mirror, Rex was confused.

"Why do you want me to choose?" he asked the voice, only for his question to be left unanswered. Thinking that the voice will only answer if he chose one of the mirrors, he walked towards the mirror of balance and reached out towards it, causing a symbol to appear before him and glow to reveal the pink video game hero before him.

"Wait what?!" he shouted as the game hero walked towards the symbol that resembled the man's helmet and stood there, facing away from the boy as he lifted his fist into the air before freezing.

At once, three more mirrors appeared before him, confusing the boy as they returned to the where the first three mirrors once stood.

What power do you seek?

Once more going in order, Rex stood before the left most mirror which depicted a young man stretching out his left arm to the side before a red spell circle engulfed him, transforming the man into a red gem-themed warrior.

"Judging from the previous three mirrors and this one...I think these must be...Kamen Riders..." he theorized.

The power of the mystic...

Inner strength.

Is this the power you seek?

Wanting to see the other options, Rex turned towards the middle mirror, seeing a man running towards a blue holographic screen, transforming him into a blue spade-themed Kamen Rider as he drew his sword, ready for battle.

The power of the warrior...

Invincible courage.

Is this the power you seek?

Rex finally walked towards the last mirror, this one showcasing a high school student lifting his hand into the air as a ring of metal appeared before him and created several wireframe lines that formed a white astronaut-like suit.

The power of the guardian...

Kindness to aid friends.

Is this the power you seek?

This seemed to line up with Rex's beliefs as he eagerly reached out towards this mirror and cause the white spaceman to appear before him and walk towards another symbol, before briefly crouching down and stretching upwards, his firsts pointing towards the sky.

"So what exactly am I doing here?" he asked the voice, hoping to get an answer again, only for the voice to ask...

You desire balance...

You seek the power of the guardian...

Is this who you are?

"Uhh...yeah?" he answered in a confused manner. This caused the two Kamen Riders, as well as all of the mirrors, to disappear before water began to form below his feet.

"Huh?" he asked as he saw a bright light appear in the distance. Rex tried to walk towards it, but the water began to recede, becoming a large wave in the processes. Immediately Rex ran towards the light before the wave hit him, leaving the boy in an large body of water. As he struggled to swim towards the light, it became brighter and brighter before he was completely blinded by it.

Rex began to groan, his eyelids slowly opening as he began to regain consciousness. He began to look around, he was no longer in that strange pool, but rather he was lying down on a bed in a room with brown bricked walls, a lamp post above him, and a large workplace and fridge to his side where someone from before was working at.

"Oww…where…am I?" he thought aloud as he slowly got up from his bed and began to massage the area where he got hit. 'That was strange...' he thought to himself, 'Just when I thought my dreams couldn't get any weirder...'

"Welcome back to the land of the living champ…" the man told him, "Glad to see that bump on your head didn't kill you..." He soon swiveled his chair to face the young boy.

The person was a young man with black hair, and was hetero chromatic with one eye being red and the other blue. He wore a long beige jacket with a white collar over a grey shirt, ripped jeans, and a pair of red and blue sneakers, looking quite mismatched.

Curious, Rex got up from the bed to find himself within a strange laboratory with a large whiteboard, a pair of small desks, but the thing that stood out in the room was a large machine with a door and some kind of microwave-like appliance.

"Oi! So you're finally awake?" Weiss noted as she leaned on a nearby wall and fiddled with her tablet, "You've been out cold for a week."

"Where are we?" Rex asked. "I can answer that question..." the man noted.

"My name is Sento Kiryu, welcome to my laboratory" the man introduced himself.

"Wha?" Rex said, still confused as to what was going on.

"One of his friends found us after we crashed landed in this time period" Weiss explained, "While today is October 1; it appears that we have traveled to the date September 24, 2017."

"Yeah…we crashed…" the young boy echoed before he remembered something, "Wait, Henrietta! What happened to her?!" he cried out in fear for his friend.

"She's fine." Sento reassured the boy, "We were able to treat her wounds with what we had. You both suffered some mild injuries; a couple of broken bones, some open wounds, nothing major apart from you receiving a massive concussion from falling onto that…rather unique vehicle you three were riding."

Sento soon began to walk towards a spiral staircase, motioning the two of them to follow him. As they walked up the steps, the three stepped out of a refrigerator, something Rex wasn't expecting, as he saw Henrietta with some bandages wrapped around her arm talking to a young girl in pajamas.

"Oh, your friend is here." the girl in pajamas told her.

"Rex!" Henrietta said as she ran to hug him, "You're okay!"

"Of course I'm okay!" the young man re-affirmed, "Why wouldn't I be?"

"So you're Rex." the man from before noted, "It's nice to meet you after what your pals have been talking about." He soon shook hands with Rex as he introduced himself, "I'm Ryuga Banjou."

"Rex Wells…" the young man said, still confused as to how he was seeing those images.

"Yosha! Now that the kid's on his feet again, I'm gonna go meet up with Sawa." Sento noted as he walked out of the door and leaving Banjou and the girl to deal with the time travelers.

"Soo…what the status on our…what do you call it?" Rex began to asked Weiss only to realize "Wait, what exactly is that machine you use called?"

"The Time Mazine" the resistance fighter clarified, "It's a battle mecha used by the resistance forces for heavy artillery purposes; and for your information, the hover mechanism on the feet were wrecked and the transformation cog was badly damaged after the crash. We were lucky that the chronological displacement system wasn't damaged either or else we would have been stuck here for good."

"Yeah, it's a miracle that you guys even survived a crash like that" the girl in pajamas noted after leaving for a bit to change into a light pink ensemble, "My name is Misora. Nice to meet you."

"So, what's the story with you three?" Banjou asked, "From the looks of it, you guys were on the run from someone. Trust me, I know how it feels…."

"So what do we do now?" Henrietta asked, "How are we supposed to return to our time without it?" Everyone soon fell silent before a large ding was heard from the laboratory.

"The heck?" Rex gasped.

"Oh, the bottle must be ready…" Misora dismissively stated.

"Bottle?" All of the newcomers asked, not knowing what she meant.

"She's talking about a new Fullbottle…" Banjou reiterated as he showed off a navy blue bottle in the shape of a dragon with a cap that had the letters D/L on it, "We use the elements we extract from these things to fight kaijin called Smash."

"So we've landed during the timeline of Kamen Rider Build…" Weiss muttered to herself, only for Banjou and Misora to look at her in surprise.

"Wait, you know about Build?!" the young man asked the resistance fighter.

"Of course, he's well known in my timeline!" she re-iterated, "So by that logic, we've come to the point in time where—" Weiss soon stopped herself, "Uhh, yeah. He's famous during my lifetime, that's all!"

"Well that's enough of that!" Rex cheered as he rushed to the laboratory, "Come on, let's see that new bottle!"

When the boy had reached the large purification machine, the oven section had opened up to reveal a yellow Fullbottle with various comic images and the letters N/C on the cap.

'A comic bottle?' Rex thought as he removed the bottle from the oven. He then turned his attention towards a pile of bottles ranging in colors and shapes along with a strange panel.

One bottle in particular, it was a purple bottle that was in the shape of a shuriken along with the same cap symbol as the Fullbottle he was holding. Thinking back to the panel, Rex noticed a series of rails on the front and so, he placed the two bottles on the same side and nothing happened. The boy was stumped once more as he examined the panel.

"Rex, what the heck are you doing?!" Weiss growled, surprising Rex as he accidentally threw the panel into the air only for the girl to catch it effortlessly.

She had arrived a little bit after Rex found the Comic Bottle, and was contemplating on letting him be before she spotted him fooling around with the panel.

"Sorry, I was just-" the boy apologized as she removed the bottles from the panel and put them on the desk.

"Didn't you learn not to touch other people's stuff without permission?" she berated the boy, who was a little embarrassed. Breathing a sigh of indifference, Weiss shook her head before shrugging, "Come on, we better plan our next move…" she told him as she motioned towards the stairs

As they walked out of the lab, Sento returned to the café with two other people. The first was a young woman with brown hair and brown eyes; she wore a black frilled shirt, a scarf, and a light pink skirt. The second was a man with black hair styled in an afro, his teeth extremely crooked, and wore a pair of hot pink glasses, a muscle shirt that had some kind of band logo, a pair of orange pants with an orange jacket wrapped around the waist, and green frog shoes.

"Finally!" Sento sighed loudly as he walked up to the counter and sat down, "That took forever!"

"Do you know how long I've been waiting?" Banjo demanded.

"So this is aniki's castle huh?" the man in the afro noted.

"Shut up!" Banjo roared, surprising the three time travelers.

'Yeesh man, what's your problem?' Rex thought to himself as he backed away.

"Welcome back everyone…" Henrietta greeted with a smile. "It's nice to see you again Etta-chan!" the woman greeted with a smile.

'Etta… chan?' the young boy asked mentally as he tilted his head.

"How's Rex?" the woman asked the young girl before looking to where said person was surprised.

"Oh, I didn't see you there!" she apologized, "I'm Sawa Takigawa, I'm a freelance reporter who's helping out Sento and the others." she said as she introduced herself.

"Who's this weirdo?" Banjou asked, staring at the one of the other new faces.

"Huh? Who's a weirdo?!" the man growled as he approached the man, only to get a head butt that sends him to the ground for his troubles.

"Is everything alright there Banjou?" Henrietta asked him, concerned about the man's anger.

"Nothing… It's fine." he noted as he approached Sento, "Can you think of some way to prove my innocence?"

"Shut up." the scientist sighed as he slumped onto the table, "I've got my hands full with this Tarou Satou thing."

"I…have no idea what you two are talking about." Rex said, shaking his head, "I mean, who the heck is Tarou Satou?"

"Papa found Sento with amnesia while Banjou was falsely accused for killing someone." Misora explained to the boy before turning to Sento, "Oh, and the bottle's ready."

Suddenly, a part of Sento's hair flipped upwards as he went from extremely tired to overly energetic.

"Really?" Sento cheered.

"Yeah, I forgot!" Rex realized, "Can you teach me how to use that panel thingy?"

"No time, I can't wait to see it!" the physicist cheered, ignoring the time-displaced teenager as ran past him.

"Hey, wait!" Banjou shouted, "You know I can't leave this place, right?!"

"This is the worst…" Weiss sighed, massaging the bridge of her nose.

Meanwhile, in a different part of the city, a young basketball player was shooting hoops. As he missed a basket, the ball bounced away and rolled into a street. The basketball player tried to go retrieve the ball, only for a truck to speed towards him. The basketball player fell backwards as the car was about to reach him, only for time to suddenly stop.

"What the heck?" the basketball player said in disbelief.

"Howdy!" a voice greeted him.

When the basketball player opened his eyes, he saw everything was suddenly frozen in place. When he looked around, he came face-to-face with a little boy. He seemed to look like he was in some kind of famine, since he was wearing tattered blue overalls, a tan shirt, rusty-looking metal boots, and a straw hat to complete the look.

"Looks like you're in luck!" the boy noted with a smile as he put his hands in his pockets.

"What tha?!" the basketball player said, utterly confused by the situation "What's going on?!"

The young boy didn't answer as he noted something, "You know, back in the old timeline, you were killed by this truck and got blasted off into a different world to become some kind of hero."

He soon picked up the ball and tossed it back to him, "However, side with me, and not only will you get to not die, but you become a world-famous basketball player. All you have to do, is defeat one man and the power is yours."

"Are you sure?" he asked, pondering on what the little boy meant.

"Yup!" he gleefully answered, before taking out a black watch of his own, "So what'll it be?"

"Fine… as long as I don't get turned into a roadside pancake." he said, making his decision, "Then I accept the contract."

This caused a dark purple projection of a clock to be created, before it's casing changed from black to purple, and the face displayed some kind of monster.

"Now that's the spirit!" the boy cheered as he used some form of telekinesis to flip the truck on its back, before restoring time and sending the truck into a nearby tree.

"Then it's settled! With the Best Match of athletic talent and other-worldly power; Nobuyuki Sakuragi, your mission is to defeat the physicist Sento Kiryu, Kamen Rider Build!" the kid declared, pressing the button and causing a dark, distorted voice to call out from the device.

BUILD…

The boy then thrust the watch into Nobuyuki's chest, a dark purple forming at the player's heart and allowing the boy to place it into his heart. After removing his hand from the chest, the basketball player began to convulse for a bit before a veil of white gas began to envelop him before dissipating and revealing the now transformed Nobuyuki.

He had a red and blue color scheme with one side resembled a mutated rabbit while the other looked like a tank-like machine. Around his waist was a series of black objects that resembled a belt, topped by some kind of device with a large crank. The monster's eyes were cracked, covered by two glass-like coverings vaguely resembling a rabbit's ear and a tank's barrel, and a large set of teeth. Finally, there was the name BUILD on its chest and the year 2017 on the back.

Back with the heroes, as the man in the afro began to get up, suddenly they heard some screaming from the outside.

"What the heck?!" Rex shouted as everyone sans Banjou ran outside to investigate. A group of martial artists were being attacked by Nobuyuki's kaijin form.

"Gah! What the hell are you?" one of the karate experts as the creature grabbed him by his neck.

"Heh, wouldn't you like to know." the monster joked in a gravelly voice.

"Is that a Smash?!" Sawa asked in fear at the sight of the beast.

"No… it's an Another Rider!" Weiss corrected her as she took out a stop-watch like blaster in her hand and fired several shots.

The girl soon rushed in and began to fight the monster, who was swiping away at her but she was dodging it effortlessly.

"Grah, I have no time for this!" Banjou growled as he shook the Dragon Bottle and twisted the cap before running in and landing a fiery punch on the monster, putting it into a dazed state.

"Thanks for the assist." Weiss said after getting back up.

"You're welcome." Banjou replied after dusting himself off. The kaijin, after recovering from the initial headache, began to look at Banjou with a curious glance.

"You…you are one of Sento Kiryu's allies, aren't you?" the beast guessed, somehow knowing Banjou's connection with Sento.

"Eh?!" the man gasped, "How do you know Sento?"

"Tell me where he is!" the monster roared before charging at the man.

"I ain't telling you, that's for sure!" he responded before dodging another swipe and landing a left hook on the beast. As the beast started to get the upper hand, Rex began to worry about the two.

"Why are you just standing there?" Weiss called out as she dodged a projection of a basketball thrown by the kaijin.

However, for some odd reason, he was frozen in fear at the sight of the beast. That's when the monster sped forward with the tank tread on its left foot to clothesline both Banjou and Weiss, causing them to drop their weapons and leaving them open.

Seeing the danger that the two were in, Rex quickly rushed to find a weapon and only saw a pile with three discarded items, a baseball bat, a trashcan cover, and a cattle prod. Without thinking, Rex grabbed the baseball bat and swung it right at the monster…however the bat soon cracked, leaving the boy with only the handle.

"Heh, what do we have here?" the kaijin pondered as Rex threw away the broken bat and prepared his fists.

"Rex, do you have a death wish?!" Banjou called out, "Get out of here!"

"I can't!" Rex replied, "I can't just let you guys fight that thing alone!"

He soon went to fight against the kaijin, but unlike Weiss and Banjou, he didn't have any way to even the odds against the beast; as such, any time he landed a punch or kick on the beast felt like he was punching a literal robot with no signs of damage.

This soon ended in him being held by his collar, before being thrown right into a pile of garbage and causing the watch to fall out of his pocket.

'The Ridewatch…' Rex thought as he picked up the watch, the face shining for a bit. He then began to remember what the man had told him about that device.

"Keep a better hold on that thing, it might just save your life…"

As he stared at the device, his courage began to return to him. Weiss soon saw the watch and began to fear something.

"Oh no... Rex, throw that watch away!" she pleaded, "If you use that device, then you might end up dooming the future! Is that something you want to risk?"

"To be honest, I'm not so sure myself…" Rex told her, "But one thing's for sure, I'm not the type to just sit back and watch someone attack the innocent like it's nothing!"

"Indeed, that's something that only you would say." the man from before stated, "Truly the words of a future king, young prince…"

"Commander Isaiah, what are you doing here?!" Weiss asked the man.

"You know him?" Banjou asked the girl.

"He's the leader of the resistance back in our timeline, and the one who trained me and my squadron since birth." the resistance fighter explained.

"Rex, for you to defy your fate, you must accept the power of Zi-O." Isaiah told the boy, "With that power, you can not only bend the laws of the present, but also the past and the future as well. In essence, you would rule all of time itself as it's king. A King of Time if you will..."

"But Rex, what if you become Oma Zi-O?" Henrietta asked Rex, worried about his decision, "For all we know, today might mark the rise of that man."

"Yeah… but I don't do something, then the future may as well end up like that no matter who becomes the demon king…" Rex responded.

"That's why you should abandon your ambitions if you don't want to that dream to come to pass!" Weiss stated, picking up her blaster and firing several shots while Banjou got his Dragon Fullbottle back and prepared himself for another fight.

Rex began to think long and hard on his next move, if he doesn't use the watch, then the future would be safe, but would lead to their demise by the hands of this monster. If he does use it however, it may be possible that he is the fated demon king of time, and thus destined to doom the world.

As he saw the monster leaped away from Weiss and Banjou and into a position where it could attack Sawa and Henrietta… Rex made his choice.

Without thinking, Rex ran leaped forward thanks to the watch and landed a powerful kick thanks to the watch's power.

"Get the hell away from them, you monster!" Rex shouted, "I've made up my mind… I'm gonna become king!"

Weiss' face began to pale a little bit as she heard this declaration, but what came next shocked the two even more, "But… if that dream is real, then some point down the line, I somehow became that monster. That's why, starting today…"

"I'm going to change that into something brighter!"

Suddenly a burst of pink energy began to crackle from the watch before suddenly, a pink holographic watch appears before the face of the watch as it transformed into something new while a mysterious voice began to speak.

THE CLOCK RIDER WHO FIGHTS WITH RIDEWATCHES IS…

As the sound of a clock ticking rang out for a little bit, Rex's watch transformed into a black watch with a white dial that had a stylized version of the katakana for Kamen and the year 2018, and turned the dial to reveal an image of a watch-like helmet with large katakana characters spelling out Rider.

ZI-O!

"The heck?!" Rex shouted, before Isaiah handed him a similar device to what Geiz had around his waist.

"I believe you are going to need this," Isaiah told the boy, "I assume you know how it works?"

Rex shook his head as Weiss was scared about what was going to happen.

"Try and figure it out for yourself then." the man said, "I'll help my pupil and the dragon buy you some time."

The man then pulled out a large black spear with neon green at the tip and a strange touch pad that connected the spear head with the base and smiled.

ZIKAN DESPEAR!

As he charged into battle, Rex began to think back to the statue from his dream.

"Rex, are you really willing to go through this?" Henrietta asked him.

"If it means keeping everyone safe…" Rex noted as he stared at the device and the watch, "…then it's a risk that I'm going to take!"

Rex soon placed the device towards his waist, a silver belt strap appearing and strapping the device to him.

ZIKU-DRIVER!

"Then good luck." she said, accepting Rex's decision and bringing Sawa back into the café, where they watched what was about to unfold through the door.

With his decision made, Rex stretched out his hand and pressed the button on the watch, a holographic image appearing as several beeps began to ring out.

ZI-O!

He then slotted it into the left side of the device, causing the screen to have images of clocks on it and the sound of a clock ticking to ring out across the battlefield before he pressed the top button to make the device slant a bit. As he began to raise his arms to the left and moved them over his head, a large holographic clock that had several gears decorating the sides forming behind him, he put his left hand towards the upper side of his body with his palm stretched outward and his right hand at the hip.

"Henshin!"

Immediately Rex closed his right hand and twisted the other around before turning the belt a full 360 and returned it back into its initial position, bringing his hands in front of him in an X position before brought them down to my side while a bell rang out from the driver.

RIDER TIME! KAMEN RIDER~! ZI-O~!

As the world began to spin for a bit in time with the driver, the hands on the clock soon stopped at the twelfth hour and the katakana characters formed and launched out of the face. Meanwhile, three watch strap-like bands and began circled around Rex to create armor around him before the katakana characters returned and attached itself onto his helmet.

Rex was now in a black bodysuit that had a silver watchstrap going down the middle, while his armor was similar to Geiz, but there were some changes, like the more rounded silver and black chest piece that had light grey shoulder pads with a pink strip above each one, his gloves being black with pink armor pieces, his boots being black with pink accents and finally his helmet being much more rounded with a pair of clock hands acting as antennae while the pink katakana characters seemed to be more contained that the butterfly-like pattern the hirigana characters Geiz had on his helmet.

"Woah…" Rex, or rather Zi-O noted as he examined the suit that formed around his body.

"Eh?!" Banjou gasped, "He became a Kamen Rider?!"

"Alright… Something tells me that I can win this!" Zi-O declared, right before landing a powerful punch on the kaijin's chest which caused a small burst of pink energy to spark out of the monster and knock it on it's butt.

"What the hell?!" Nobuyuki growled, "How did he get this strong so fast?!"

"What can I say? I aim to please!" Zi-O quipped before the monster got to his feet and swiped at the Rider.

Zi-O then began to dodge the attacks, while countering with his own in a quick back and forth exchange.

As the two combatants grappled with each other, Isaiah sees that it's safe as he went to check on Weiss and Banjou, who were watching the battle unfold.

"Are you two alright?" the man asked.

"Why?" she questioned, "Why did you let him use the watch?"

"I see the potential for him to be a Kamen Rider just like the others…" he noted as he watched Zi-O was being hit by the basketball that the Another Rider was throwing at him, "His heart was already in a good place to start, he just needed the tools to do so."

Back to the fight at hand, Zi-O decided to reach out his hand and summoned forth from his belt a large beefy sword with the katakana for "Sword" on it, along with a trigger and a place where a Ridewatch could go.

'Woah, a new weapon?' he pondered in his head.

ZIKAN GILADE!

KEN!

However as the Another Rider prepared to toss yet another basketball at the Rider, Zi-O blocked the oncoming attack with the side of the blade. With this new weapon in hand, Rex began to outpace the monster more and more as he landed several slashes that were charged by the Ridewatch's power.

"Let's finish this!" Zi-O declared as he returned the sword into the driver and pressed the button on the watch before slanting the device.

FINISH TIME!

The monster soon responded to this threat by summoning yet another basketball and leaping higher into the air, preparing for a slam dunk-like attack. Once the boy spun the driver, the Another Rider was halted by a ring of pink katakana characters spelling out the word "Kick".

TIME BREAK!

Rex then leaped into the air and towards the monster, allowing the characters to hit the kaijin repetitively before fusing with the markings on the sole of the Rider's right boot.

ZI-O CHRONO KICK!

This was enough to knock the Another Rider out of the sky and into a nearby bush as he changed back into Nobuyuki, the watch falling out as the boy's body sprawled onto the grass.

"That… was… awesome!" Rex shouted as he removed the watch from the driver, causing his armor to disappear in a pink light before everyone gathered around him.

"That was a pretty cool battle!" Sawa noted as she took some pictures of the boy's new device.

"Rex, are you okay?" Henrietta asked the boy, worried about her friend's safety.

"Yeah, I feel great!" Rex said as he stretched for a bit, "I felt like, for the first time ever, I had the power to protect the people I care about!"

Seeing that her friend was okay, she gave a sigh of relief as Isaiah turned to the boy with a reassuring look. "So, how does it feel to become the final Heisei Rider?" Isaiah inquired, shocking Weiss.

"Wait, he's the last of the Heisei Riders?" she asked, surprised that this boy was the one the resistance base was talking about," So that's why…"

Weiss soon began to ponder something as Banjou gave the young boy a pat on the shoulder, a big smile plastered on his face.

Come on, we better see what Sento was doing…" Banjou told Rex, causing the boy to smile as they all returned into the café.

However, as he opened the door, he could not help but feel like something was off. He felt like...someone was watching him. As he looked around, the boy simply shrugged his shoulders and walked through the door. However as soon as he did. that's when a young man walked out of the alleyway and groaned. The person looked to be in his late teens with dark green hair, and grey eyes. His outfit was pretty simple, merely consisting of a black bullet proof vest over a jungle camo jacket, a pair beige combat pants, and black army boots.

"I wasn't able to stop him from transforming." he muttered to himself, right before he gripped the red and black Ridewatch attached to the holder of his arm, "But that doesn't mean that I'll stop him from dooming the future…"

CURRENT YEAR: BUILD 2017

THE NEXT CHAPTER OPENS!

"This timeline is only one of several in the time-space continuum."

"Interesting...Ya want to team up for a bit?"

"I'm gonna make sure that knucklehead doesn't get himself killed…"

"Here I come, Oma Zi-O!"

NEXT TIME ON EDGE OF TIME! READY GO! 2017

"The future is mine to decide!"

AUTHOR'S NOTE CIRCA 12/19/2019:

Hey guys, Hacker here! I know that it's been a hell of a long time since I've posted anything on this account but a combination of real life and dealing with a lot of stuff with the reviews and Spacebattles has kind of made me really burnt out on writing.

However that doesn't mean I haven't stopped working on my stories because I'm still making good progress on both EoT chapter 9 and Mystic Legends chapter 6 and I'm hoping that I can post them a bit after Christmas at the earliest, and around early next month/year at the latest.

Even still, I've decided to try and re-work my earlier chapters since I've mostly been writing these stories as pseudo-novelizations, with large paragraphs that included both descriptions and dialogue. That's why for the rest of this month, I'll be revising both stories with a new format, as well as some changes and fixes that would help make the story more streamlined.

I'll be doing these kind of revisions right until I post the new chapters of EoT and Mystic Legends, so look forward to that.

Until then, this is HackerEX logging out! See ya!

AUTHOR'S NOTE CIRCA 7/14/2019:

I'M BACK! AND BETTER THAN EVER! Hey guys, Hacker here! Welp, here it is! The first chapter of the of the rebooted Edge of Time!

As you can see, the entire chapter feels a lot different from the original, which I felt just rehashed the first episode of Zi-O with some minor differences here and there. This one however feels a lot more like a proper adaptation, following similar beats to the original episode, but can stand out as it's own chapter. Also, if you couldn't tell, the new Build Arc takes place during episode 5 and 6; this is a part of one of the bigger changes I have planned for use in this new chapter, that being that the story structure will be more like Battride War Genesis, where the characters will travel through different points in the Kamen Rider timeline.

Another change is the focusing less on bringing different franchises into the mix, this will mostly focus on the characters jumping through several subsections of Kamen Rider no Sekai, like Build no Sekai, or Amazons no Sekai. However, this also means that the Heartless will show up at one point, but the good news is, so will Sora and friends! In any case, if you want to know the full order of each Rider the heroes would travel to, here's a hint; I've teased it via that little soup of quotes from the various seasons. There's also going to be a minor change with the Rider Links, but that's in the future for you if the chapter 2 teaser is anything to go by.

Back to the chapter itself, in the original Another Build was a nameless basketball player that was chosen at random, the same was technically true for the original EoT. However this time, I decided to make the first Another Rider a guy that was originally going to become an Isekai protagonist had it not been for Famine. Plus, if you translate Nobuyuki's first name into English, it translates into faithful happiness, which is ironic considering that he's causing pain and anquish as a kaijin.

Now when it comes to the new uploading schedule, I'm going to settle for the Kamen Rider tradition of a new chapter being posted every week, while, as obvious as the past chapters have been, Mystic Legends will probably be a monthly series with one or two chapters uploaded every month. So, what did you think about the new direction? Do you like it? If so, then leave a review and tell me what you think?

Until next time, this is HackerEX logging out! See ya!

UPDATE: {7/6/19}

Hey ya'll! Just wanted to do some quick fixes to the story (correcting some errors, adding extra dialogue to flesh put certain scenes etc.) along with changing the name of next week's chapter because I want the Build Arc of my fic to be like the Kuuga Arc in Decade.
