Date: December ?? 2019.

Location: In the ruined city of Fuyuki.

Sougo and Takeru followed their first predecessor/resistance leader, Takeshi Hongo, onto the lab where the portal is awaiting. Once the three entered the ruined entrance of the lab, they saw a neatly fixed lab once they got in. What? This is Sento we're talking about. Not the plot. And also, Sougo's Time Mazine is positioned in front of the portal.

(Time Mazine)

"Alright, this baby might take you to the other dimension ASAP, just like what we all wanted." Sento, known as Kamen Rider Build, stated as he pats the activated portal beside him.

"We know that, Sento. We know that." Sougo said, "Are there any more things that we need know?"

"Nothing but to say good luck when we sent you two back in time." Philip said as he stood beside Sento with a smile, "And I made a device where you, Sougo, can contact Geiz and Woz when you three need to form Trinity Form..... if that would happen, but not to worry! This device can also create a vortex where Geiz and Woz can travel through, but once you've dehenshined back, Geiz and Woz will be forced to return here."

"Heh, thanks, Philip. Thanks, Sento." Takeru bowed to the right side of Kamen Rider W/Double as he and Sougo turned around and looked to the activated portal with bags and cases strapped on their backs and in their arms, which only contained their other needed stuff.

Those needed stuff are mostly the Ridewatches, that the Prime Riders halfly gave to Sougo, the Eyecons, Ghost Gadgets, which were in their Gadget mode, and clothes. Oh and also their grooming stuff as well.....Then the alarms turned on as the five Riders inside began to heard an explosion outside.

"Shit, we got another raid!" Takeshi said as he equips his Upgraded Typhoon, "Sougo, Takeru, you two need to go, now!" with that, he ran out from the lab as he screamed "Henshin!" to support the Riders from the Altered Servants. Sougo and Takeru were about to ditch the mission and help their leader, but Philip and Sento blocked their way.

"I know you two are worried, but don't worry. We'll be fine, just go in there and do what you guys are told." Sento said with reassurance and it made Sougo and Takeru to be hesitate about it, but they gave in with it as the two turned around and ran to the Time Mazine.

Inside, Sougo went to the controls as he began to press some buttons for their ride to activate.

"Systems are all green, Time Mazine ready for take off. Oh, and don't forget to transform as well." Sento said through the Tine Mazin's speaker.

"Right." Sougo said as he and Takeru henshin-ed into their default Rider Forms.

(Kamen Rider Ghost: Ore Damashii)

(Kamen Rider Zi-O)

Zi-O looked to the screen that shows the portal, "Zi-O and Ghost heading out with the Time Mazine!" with that, he thrusts the panels of the Time Mazin, causing the Time Mazin itself to fly towards the portal.

-History is Written in Time!-

Date: ????? ?? 2004.

Location: Fuyuki.

Fuyuki, a once peaceful city, but...... right now it's in flames and in ruins. Speaking of which, we see a young woman running away from a bunch of skeletons.

(Olga Marie Animusphere)

(RF2: Well ain't she grumpy......but still cute.)

Olga have enough with these undeads so she decides to give them some of her Gandr shots but the sheer amount quickly overwhelm her. Fortunately, Mash Kyrielite come to the rescue with her shield.

Even though the purple hair girl doesn't have any skills yet but her physical power was enough for these undead creatures.

(Mash Kyrielite)

However, before Marie grasp the situation happen before her, a strange boomerang came out of nowhere, hit a few skeletons skulls before return to Ritsuka.

(Ritsuka Fujimaru)

The director turns around to see candidate 48 with Fou on her shoulder.

(Fou)

"Director?" the girl seemed surprised to see her.

"You?" the woman exclaim

Mash quickly use the bottom of shield to cut the skeleton into 2 before smash her shield onto the ground, create a powerful shockwave that destroys the remaining skeletons. After that, the girl quickly ran to Marie "Director? Are you hurt?"

"What is going on?" the women ask fearfully

"This is Singularity F, Fuyuki, 2004." the purple hair girl replied, "Also, I think that-"

"You've become a Demi-Servant, right? I could tell just by looking at you!" the white hair women cut off the girl words, "What I want to know is, why it didn't it succeed until now!" stated the director as she stood up.

"I'm sure you know that Chaldea prepared a Servant beforehand in order to resolve the investigation of Singularity F. Right before I died, he offered me a contract: in exchange for giving me the abilities of a Heroic Spirit and Noble Phantasm, he wanted me to eliminate the cause of the Singularity. So I merged with the Servant to become a Demi-Servant." Mashu recalled the memory of the spirit of what appeared to be a knight whose identity was shadowed.

"And this unknown commoner has become your Master?" Olga Marie turned to Ritsuka, who's clueless.

"Master.....?" Ritsuka said as she slowly realized what Olga meant, "Eh?!? I'm a Master?! But..." Ritsuka was about to reach out to Olga, but she noticed a command spell was on her right hand.

"That command spell proves it." Olga said as she looked back to the surprised Ritsuka, arms crossed.

Ritsuka's bracelet begins to beep, which made her yelp in surprise, the woman presses the device as a hologram screen appears from the ground next to Ritsuka. The person on the screen reveals to be Romani.

(Romani Archaman)

"I finally got through? Hello, can you hear me?" the man voice was coming from the screen.

"Dr. Romani!" Ritsuka exclaim.

"Ritsuka, Mash! So you did get caught up in that Rayshift. Without the coffin-" Roman quickly got cut up by Marie.

"Why have you taken control, Romani?" the woman asks angrily.

"Director? You're alive?!" the doctor shouts in shocked

"What're you talking about? And why is the head of the medical section in that chair?" the white hair women crossed her arms.

"Where's Leff?" Marie could feel her patience run thin.

"...Professor Leff was right in the middle of that explosion that took place in the central control room." Roman reported with a regretful expression. "I can't see any hope of his survival."

"No..." Olga Marie was shocked at the loss of the man while looking ready to cry.

"The reason I have been entrusted with the operational command is because there isn't anyone left who outranks me."

"What about the master potentials? What happened to the 47 people who were in the Coffins?!" asked Olga Marie with a distressed look.

"All of them are in critical condition. At this rate.."

"Don't be foolish!" shouted Olga Marie, surprising the people present. Then she more her arm forward as a gesture of direction. "Transfer them to cryopreservation immediately! Our top priority is to ensure their survival!"

The doctor understood what she meant, since that would keep them alive even in their heavily wounded conditions. "I'll do it immediately!" shouted Roman as he got out of the chair and ran off.

After watching that, Mashu turned to Olga Marie with worry since that her order could be considered criminal. "Director... You do realize that-"

"As long as they don't die, this can all be justified later. I can't possibly carry the burden of 47 lives on my back." The girl said as she bit her nail in frustration.

-History is Written in Time!-

With the Riders, currently the Time Mazine and themselves are flowing through the vortex. Inside, we see the Riders just chilling inside.

"Are we there, yet?" Ghost started because boredom has succumbed him.

"Not yet." Zi-O replied as he kept piloting. Then something happened and Ghost is the only person who noticed it.

What did he notice you ask? Their duffel bags and the suit case began to glow.

"Dude, something's wrong with our stuff." Ghost warned as the time rider looked to their stuff, which in return bursted out from it. Zi-O began to panic when the Ridewatches, Eyecons and the Ghost Gadgets began to wander around inside the cockpit.

"What happened?!" Zi-O asked as he ducked the Condor Denwor in it's Gadget Form when it went passed him, followed by the other Ghost Gadgets.

"I don't know!" Ghost yelled in reply as he covered his head with his arms. The button to open the cockpit was pressed by an unknown force or such, causing the door of the Time Mazine to open.

The Riders began to panic when all of their stuff went out of the Time Mazine.

Well, except for their clothes. Ghost was about to catch onto their needed power-ups and friends, but the door was closed shut.

"Guys...... no....." Ghost said with a depressed tone....... until the Time Mazine began to shake and heard a explosion, "Sougo, what happened?!" Ghost looked back at one of his successors. Zi-O looked to Ghost with a panicked expression behind his helmet.

"Some parts of the Time Mazine overheated and explode for unknown reasons!" Zi-O answered as he tried to control the Time Mazine, "Brace yourself, because this ride is about to get shakey! No pun intended!"

Ghost did what Zi-O told him as the two riders are about to find out what happens to themselves.

-History is Written in Time!-

"Currently, Chaldea has lost 80% of all functions. Once with the communications outside are restored," Romani started while inside the Chaldea, "I'll request supplies and start reconstructing Chaldea. That's the status."

"Fine, Romani Archaman." Olga said while talking through the hologram screen, "I'm not happy about it, but until I get back, you're in charge of Chaldea."

"Roger. But still..."

-With Ritsuka-

"A Demi-Servant, the fusion of a Heroic Spirit and a human..." Romani commented to Mash's current state, which also made Olga to look back as well, "I can't believe it succeeded at a time like this."

When Olga looked at the two, they witnessed that Fou is patting his paws to Ritsuka's cheek, which entertained Mash. Olga then looked back to the hologram.

"Well then, starting now, both Ritsuka Fujimaru and Mash Kyrielight will begin investiga-" Olga was cut off when Romani's face was panicked when he looked to what's behind Olga. Olga sighed as she was about to look behind, but Mash immediately grabbed Olga and forced themselves to jump and roll to the side to see what was about to crash onto them. Olga looked to the thing that crash landed, it appears to be the Time Mazine and it was in side ways, and the three girls themselves didn't know what that is.

The Time Mazine itself was in flames, well for some parts, and Olga ordered Mash to investigate, which she did. As soon as Mash was near, the Time Mazine's cockpit door opened and Takeru, who's still in his Ore Damashii, was thrown out from it.

"Get out, get out it's gonna blow!" Sougo, also in his Rider Form, screamed as he jumped out of the about-to-be-explode Time Mazine as he and Ghost went to the girls.....which exploded afterwards. While that happens, Mash uses her shield to counter the explosion and Ritsuka, Olga, and Fou are behind her. As soon as the explosion was finished, the people sighed in relief.

"Mash, quickly take those Undeads out!" Ritsuka quickly commanded Mash as Mash herself agreed and charged towards the Riders.

"Understood!" shouted the girl before she charged the warrior with her shield at the ready to attack the undead warrior. Then she jumped and prepared to smash the long end of her shield into the Riders..

But what she didn't expect was the two undeads to start talking.

"Wait! Wait! Wait! We're not here to fight!" shouted the pink clock warrior in a male voice with his hands raised in a surrendering and panicking fashion.

"Huh?!" Mashu wondered before she let gravity take her and the riders had to jump out of the way as a rock was pulverized behind them. Ghosy rolled on the ground before standing on his feet while raising his hands again to show that he didn't want to fight. Same goes for Zi-O

"Wait for a moment, and let us talk!" shouted Zi-O.

Then Mashu placed her shield in front of her while looking suspicious of the suddenly talking undead. "Aren't you two here to kill us?"

"Kill you!? Of course not!" responded Gjost as he still had his hands up.

"Yeah! We're only here to talk to you since you three are the only other humans that we met in this city!" Zi-O added

"Human? You two don't seem like one. Especially that one." Mash stated while sizing up the two Riders, especially Ghost.

"Oh, you have a good point. I forgot how this form usually scares people. Hold on." Then Ghost moved to an odd looking belt on his waist before opening its lid and taking out an eye-like sphere. Then he closed the lid as the belt announced.

Oyasumi!

Zi-O also did the same as he pulled off the Zi-O Ridewatch from the ZikuDriver. Once done, the two riders were replaced into their physical civilian forms.

"See? We're human!" Takeru said as he tried to walk forward only for Mash to point her shield at him. "Eh?"

"What are you? To shift between that ghost form and human means that you really aren't an ordinary human." asked Mashu who did not expect the warrior to transform into a human form. This only made her more suspicious of the person in front of her.

"Especially you!" Ritsuka pointed to Sougo.

The young man raised his hands in surrender while sighing that he and his ghost companion didn't made any progress, "You got to believe us! We're humans!"

Meanwhile, Olga Marie and Roman were stunned by the new information about the warrior while observing the exchange between the two.

"What in the world? What are those guys?" wondered Roman.

"Those two are obviously not humans if they could transform into human form so easily." Olga Marie said with an unamused look, 'Unless they're from another universe.......Just like what he told me...'

Sougo closed his eyes and yelled out his and Takeru's mission, "You've got to believe us! We're humans! We're just here to stop the Altered Servants for reaching our universe and the multiverse!" And that is where both Olga and Romani began to take interest as they looked back to Sougo and Takeru.

"Universe?" The girls, plus Romani, repeated.

"Yes. The multiverse is real." Takeru said.

"And we're from the future of another universe in another world." Sougo added.

"Wait, what do you mean by world?" Romani asked the riders, because it is his first time hearing this.

"It's really hard to explain since the author doesn't know it. Even though he also didn-"

"Let's just say it's a parallel timeline.....but....it's different." (A/N: Please correct me if I'm wrong about this. I haven't watch Kamen Rider Decade, yet.) Sougo explained, "You get me?"

"Sorry, no." Romani said as he shook his head, which caused Sougo to sigh. With that aside.....

"Do you know where we are?" asked the director.

"We're in some place called Fuyuki, right? Though... this is the first time, I went into the another universe's past..." Takeru said as he scratched his head.

"Wait, you also traveled into the past? But why?" asked Olga Marie though she did looked doubtful of his story.

The warrior's eyes made a sad expression as he looked down. "*Sigh* Because where we came from... our present was in a brink of a war....."

"He's not wrong... We were fighting a large group of altered servants." Sougo supported his friend's story.

Mashu gave a shocked look along the director and doctor after learning this information.

"What was the date you came from?" demanded Olga Marie who needed to be sure they were telling the truth.

"December 2018." Sougo answered as he sat, still sad about his universe's world's war along with Takeru.

"So... they really are from the future.....but only in a different universe." said Ritsuka.

"Um... before you can continue questioning us, can you at least tell me who you people are?" asked Sougo with curiosity as he stood up with his predecessor.

"He does have a point, Director." Roman stated. "We can't have our new friends be mistrusting of us."

This made Olga to sigh, "True. I am Olga Marie Animusphere, Director of Chaldea. The commoner with orange hair is Ritsuka Fujimaru, our first Master. The girl in armor is Mashu Kyrielite, a Demi-Servant. The useless-looking man at the console behind me is our head of medicine, Doctor Romani Archaman."

"Nice to meet you, guys." Ritsuka smiled as she waved her hand.

"Nice to meet you, boys." Romani said as he bowed his head, the riders did the same in return.

"Nice to meet you, and sorry for the misunderstanding." Mash apologized as she just looked down onto the ground with shame. Takeru just looked at her with pity as he went to her and crouched down to her level. Then, he gave her a head pat....which surprised the Demi-Servant.

(RF2: Just like this, but remove the other arm and the vigorous part.)

"Don't worry, we're not mad. And it's also not your fault." Takeru reassured as he take his hand off of Mash's head, who is still surprised.

"Anyway.....since you guys already introduced yourselves, it's time for us to introduce ourselves as well." Sougo started as he began to introduce himself and Takeru, "My name is Sougo Tokiwa. Average high-schooler and I'm a king!"

(Insert Cricket noises)

Everyone, minus Takeru, just looked at Sougo. Takeru just sighed and told them to deal with it, which they did.

"Or so I'm told....which already did happened.....in the future." They ignored that.

"Takeru Tenkuji, a ghost hunter and heir of the Dai-Tenku Temple. Nice to meet you all." Takeru greeted.

"Tenkuji.....?" Olga muttered as she began to ask Takeru a question that he didn't expect, "Are you somehow related to Ryu Tenkuji?"

(Insert Cricket Noises)

"Huh, looks like the crickets here survived. That's good." Sougo said in relief as Ritsuka nod in agreement.

"You know my father?" Takeru asked Olga, who just nod in return, "Looks like Otchan didn't tell me something about their past.........."

"Otchan? You mean Edith, right? You also know that old geezer?" Olga asked, now that the two are having something in common.

"Yeah, he is the one who gave me the powers of Kamen Rider Ghost after I died." and insert another cricket noises.

"Okay, why is this becoming cliched already?" Now Romani complained, but they ignored him.

"I'll answer your questions for later, but back to the topic. How did you know my father and Otchan? Did they helped you or something?" asked Takeru with surprise though he did hear from Onari, his caretaker, that his father did some other works with different associates from all over the world before he settled at the temple one day, probably after marrying his mother.

Olga Marie nodded. "Yes, without him and Edith then Chaldeas' time travel theory and the multiverse theory would have been delayed and we wouldn't have met you here. So will you lend me, no, us a hand in this crisis?" She offered her hand to him.

Takeru gave her offer some thought before he smiled and nodded. "Of course, the future is still burning bright! We'll save it!" Then he shook her hand with his bright smile still present

"How about you, Sougo? Will you lend us a hand?" Olga asked as Sougo smiled in return.

"Of course! As a king, it's my job to make sure that my people in need are alright!" Sougo said proudly and everyone, besides Takeru, just looked at him like he's crazy. And also....

"Okay, seriously. This is becoming cliched already." Romani complained again, and yet again, the others ignored him.

"You're a king?" Ritsuka asked, because she can't let it slide the part about Sougo being a king.

"In the future, yes. But as a vile demon king." Sougo said, "And I will not become that vile demon king. Since I'm changing that fate, I will become the greatest, most beloved and kindest demon king!"

"Uh-huh....." everyone, besides Takeru and Ritsuka, just nod and shrugged it off.

Mashu then realized that something missing. "That's right! Where's Fou, sempai?"

"Now that you mention it..." Ritsuka also realized that she lost track of the creature when the Time Mazine crashed landed.

"Fou!" The white-furred creature appeared from behind a wrecked car and jumped onto Sougo's shoulder.

"Huh?! What the?" wondered Sougo as the creature climbed onto the top of his shoulder before jumping towards Ritsuka, landing on her head. Then it traveled off of her head and landed on her right shoulder. "W-What sort of animal is that?"

"This is Fou, Sougo-san." Mashu said as she petted its head.

"Fou?" Sougo wondered before he approached to look at the furred creature.

"Is it some sort of Youkai?" wondered Takeru though the creature snorted in anger at his assumption. "Uh sorry, I guess you aren't one, Fou-san." The young man smiled and scratched the back of his head in embarrassment.

Meanwhile, the director was turned to Roman after deciding their next course of action. "Well then, starting now, both Aka, Mashu Kyrielite, Sougo Tokiwa, and Takeru Tenkuji will begin investigation on Singularity F." Olga Marie said before turning to the four who gave determined looks upon noticing her attention was on them, "Although this team consists of inexperienced members, the mission will be to discover the source of this singularity's existence."

"I wish you luck, if an emergency comes up, please contact me." Roman said.

"Hmph! We can send an SOS, but nobody will come save us."

"But Director-" Then Olga Marie cut the signal off, interrupting the doctor's protest.

"After this incident, I can imagine how much protest we'll get from the Association." Olga said as she looked down with her fists clenched tightly, "We can't go home empty-handed. Understand?" asked Olga Marie.

"Roger!" responded Mashu.

"Understood!" Ritsuka said with a confirmed nod.

"Alright!" shouted Sougo with a nervous tone as he stood awkwardly straight.

"Got it!" Takeru nodded with an affirmed tone.

"I never the day would come when I'd have to rely on a commoner." Olga Marie did not like the circumstances at hand. Then the five heard a beeping sound and the director rolled up her wrist to reactivate her connection to Chaldea, "What is it? Can't you see how annoying-"

"Please get away from there right now!" shouted Romani.

Mashu also sensed the danger and turned around with an alarmed look. "I'm detecting signs of an enemies! One of them is a servant, but for the others.....they're unknown for me."

"Unknown?" Marie looked to Mash with a question look.

"Yes, but-" Mash was cutted off by Sougo before she could continue what she's about to explain.

"Discuss this later, right now we need to get out of here!" Sougo suggested quickly as the girls, and Takeru, nod in agreement.
