Prologue

1273: A tale of a wandering knight

Unknown POV

On an unknown desert

Year 1273

As the desert winds rages, we saw a white-haired knight wandering. As he stops, he saw a skull and starts to reach for it as a voice started to talk in his mind.

"Fulfill a sinner's wish..."

On an unknown flower field.

Unknown year

We then saw the knight in stone… As the voice continues, "This is without a doubt… Your last chance, no matter the outcome of the battle, you will die in this way. Squandering your soul. Departing from the cycle of rebirth, you will turn into nothingness." We then saw a silhouette of a white Wizard with two men alongside him being Tsukasa Kadoya and a man in snake clothing, "Even so, will you rush towards the end of your journey?"

"Yeah, are you ready for this journey?" Tsukasa asked, as the Knight started to rise.

"Will you have the power to pay the price?" the Snake man interjects.

Back at the desert

Year 1273

We then cut back to the knight as he clenches his right arm, "I see, this is the end of my journey. This time with my own hands. I will kill my own king."

He then starts to walk as we saw a white city from a far.

(Cue Opening Theme: Over Quartzer by Shuta Sueyoshi Ft ISSA)

the 'Grand Order' continues with the Kamen Riders and Chaldea facing up against the Knights of the Round Table. Rejoice for the quest for Humanity's future Continues.

Oh, yeah, Oh...

We saw Mash, Ritsuka, Roman, Da Vinci look and marveled at the Rider kicking Kamen Riders, when suddenly they saw Zi-O, Den O, Ghost, Build, Wizard and Decade walking as their faces are now shown.

sshun de tsukamitoru no sa Are you ready? (Are you lazy?)

We saw Sougo, Ryotaro and Ritsuka look at the clocks as they reach it, they then swing their arms the background starts rotating.

Atarashī rekishi wa soko ni Feel it! Feel it! (Crazy baby!)

We then saw Geiz throws his cloak as he transforms to Kamen Rider Geiz.

Feel it! Feel it! (Crazy baby!)

With Tsukuyomi and Mash walking as Tsukuyomi changes to Kamen Rider Tsukuyomi.

Hikari wo kate ni kasokushite

We then cut to Sougo and Tsukasa who then transform to Oma Zi-O and Decade Violent Emotions as their eyes turn red and slanted.

Konomama Shout it out! Shout it out!

We then saw Takeru appear with Makoto, Alain as well as the Heroes of history. With Roman, Sento, Haruto and Da Vinci at mission control

Ima wo susume yō

We then saw Woz turning his book as it shows a shadowy figure with white hair and black eyes.

Madō hi mo Ikudo tonaku Asu no tobira

We then saw the Shadowy figure as he walks, as an image shows the Heroes doing their daily routine. As we cut to Woz's book showing Oma Zi-O destroying things as well as the Shadowy figure sending creating golden cups.

As it changes to a white version of Woz. As we saw the Ridewatches.

Mitsumeta sono saki ni

We then saw the statues of the Riders appearing as Geiz activates his Ridewatch.

Tobikonde mitara

As the statues continue to appear, as Sougo activates his watch with Ritsuka, Tsukasa, Takeru and Ryotaro watching him.

Believe Yourself!

Sougo, Tsukasa, Ryotaro and Takeru transforms into their Rider Forms.

Toki no ame Surinukete Tomo ni

We then saw the Riders riding their backs, as Shadowy figures started walking. As the Rider kicks started moving.

You, Over "Quartzer"

We then saw Zi-O riding through the blaze. As Gaim and the Armored Riders, Blade Riders, and Ryuki and Knight emerge.

Mirai wo koe yō

We then saw heroes standing with serious looks on their eyes. With Artoria Pendragon splitting into her three aspects. With Bedivere looking at his right arm as shadowy figures that resemble Artoria and the knights surrounds him

Kako no ishi wa Uso de wa azamuke nai

We then saw the Riders as well as the Servants fighting some enemies. With Woz using his Kamen Rider Ginga Miridewatch.

We then saw Tsukuyomi and Mash walking down the stairs, as the scenery started changing. With Natsumi, Medusa and Kaitou appearing to take their hands.

Now, Over "Quartzer"

We then saw Zi-O using his sword.

Mabayui sekai Misete

As it switches to Geiz with them duking it out as the title appears.

Ritsuka POV

On the holy land

Year 1273

We then saw Sougo, Tsukuyomi, Geiz, Woz, Ritsuka, Ryotaro, Sayo, Aruto, Takeru, Haruto, Mash, the Artoria trio who for some reason are wearing visors and cloaks and with their Artoria and Artoria Alter's down, and Banjou riding on a vehicle that was made by Sento and Da Vinci who are now driving it.

"Wow!"

"So cool."

"How do you feel, Fujimaru? Mash? Tokiwa? Everyone? It was made of scraps, but it's pretty good right?"

"So, what's your opinion, guys? It's amazing, right? It's fantastic right? It's genius of us, right?" Sento asked.

"Geez, you never cease to question us about that huh, Sento?" Banjou muttered.

"You two are certainly in high spirits, Da Vinci-san, Sento-san."

"Well, of course, we weren't able to enter a singularity together."

"Yes, we're counting on you two."

"And we mean it too, you know." Sayo said.

"You got it, Mash." Sento replied.

"Yeah, and also, why is Artoria and her other selves dress like that?" Woz wondered.

"It's none of your business prophet."

A screen then appeared, and it shows Romani, Hana, the Taros, Medusa, EMIYA and Jeanne D'Arc Alter, "Romani here. Let's go over the situation, shall we?"

"Please do."

"Do it, Doc."

"Alright, you're all currently in the year 1273. The ninth crusade failed; the Catholic Church lost its influence over Jerusalem."

"So, then that means…"

"Yes, the Mamluk Dynasty, the Mongol Empire and the Christians were in discord."

"Probably the one who hosted the Holy Grail was one of the survivors of the Crusaders. The Holy Grail has always gone… to the ones who lose."

"Yeah, so good luck out there." Jeanne Alter agreed.

"The Holy Grail."

"But then again, is this really… The Kingdom of Jerusalem." Mash asked.

"I agree it doesn't look anything in the history books." Sougo, Ryotaro, Takeru, Tsukuyomi, and Geiz said.

"According to the coordinates… the citadel's fortress should be here, but…"

"It seems like something happened already. A perfect example is that…"

"What do you mean?" Artoria asked.

"Just look over there." Sento and Woz said as they pointed to a white city.

"A city?"

"A castle…"

"EHHH!"

"According to the architectural design, it clearly does not belong to this land." Da Vinci said.

As they look on, they heard Da Vinci and Sento shouted, "Oh no!"

Their vehicle jumps and starts skidding as it tumbles… We then saw that Sougo, Banjou and Ritsuka are holding the vehicle up, with Sento and Da Vinci checking it and the others just standing.

"Oh! It flashed! Because of the jump, this part got detached."

"You said it, Da Vinci take a good at this too." Sento shouted.

"I see the atmospheric mana was absorbed… and dissipated at the same time. This is why…"

As this was happening Ritsuka muttered, "This is why I can't tolerate a genius!"

"Now you're speaking my language, Ritsuka!" Banjou agreed.

"Are you alright, Sempai, Tokiwa-san? Banjou-san?" Mash asks Ritsuka and the others.

"Yeah, looks you need some help." Haruto said.

"I agree let me fix this thing." Mash exclaims as she starts to lift the vehicle up until it was in its former position.

"Wow!"

"That's so Mash."

"Yeah, you're amazing…" Aruto said as the other Kamen Riders and the Artoria trio smiled.

She then smiled at the others, when they heard Da Vinci and Sento shouting, "Hey!"

"What is it?" Sougo asked.

"Take a look at this." Sento said. They then walk towards Da Vinci and Sento's location, where they saw a hole littered with blocks.

"This is..."

"These aren't ancient ruins…"

"Wait… you mean." Tsukuyomi was about to say.

"How…"

"This is... a much worse situation than we expected." Da Vinci said.

"You're right, I sense something interfering with this world." Woz agreed.

"Let's go…"

"Yeah, we got to fix this world and quick." Sougo said.

"Although I wonder where Tsukasa, Natsumi-san and Kaitou-san at?" Tsukuyomi, Haruto and Geiz said.

"I agree where could Oniichan be?"

Hope you like the prologue, it's kind of short… But that's all I could think off.
