Author's Notes:

Hello guys! It's another time for another chapter of the Camelot Singularity, last time the Knights of the Round Table sans Lancelot are now getting reports of the heroes' activities… With Agravain advising the Knights to defend the city until the Lion King completes her work. Meanwhile, back at the Heroes' side they are now trying to think of a plan to attack the city. With the Hassans vowing to kill Tristan with the Shindai Siblings, Ren and Desast volunteering to assist them.

Later Sougo, Tsukuyomi, Ritsuka and Mash are discussing about Bedivere. With Ritsuka contemplating about Bedivere's sin as he asks Mash about the latter's backstory, Mash then started to tell them the story… As she finishes, they still don't know what is Bedivere's sin, but still Ritsuka thinks that he can still be trusted. The next day Bedivere wakes up as Ritsuka, Kouta and Sougo comforts him.

Quartzer 4

1273: The beginning of the siege.

3rd POV

Outside the Holy City, Holy Land

Year 1273

We then open to the heroes now at the heroes now lining up to attack the city, with Lancelot shouting, "From now on, we shall tear the Holy City! For the sake of all who live in these lands… Everyone, take up your weapons! Now is the time to turn the land to how it was before!" The troops cheered and raised all their weapons. As they started to charge.

"The plan is this Sir Lancelot and his men, will try to stall Gawain. Meanwhile, we'll go through the main gate. Once we enter the holy city, there will be several routes to reach the throne."

As they charge, they saw Gawain touch down while proclaiming, "Here the gates of the Holy City… Regardless of the evil I face, my Sun shall burn it down." He then starts to wreath Galatine with flames and started to unleash it towards the heroes, only to be blocked by Lancelot.

"Sir Lancelot, you really disappoint me."

"No matter what you say, this is also my loyalty to the King. Ever since I received the Gift of Ferocity, it has been my duty!"

"Yeah, so stop being such a judgmental A***hole, Sun Bastard!" Den-O shouted.

He and the Kureshima siblings then charges at Gawain, "You're just like that, aren't you? However!" He then pushes the three back declaring, "The Nightlessness that was entrusted to me, shall wipe the clouds standing in my way!" He then started fighting the three pushing them further back... He then turns his attention to the troops as he ignites Galatine again. Only for Bedivere, Gaim, Blade, Ryuki and Saber to block it. As Mai, Sayo, the Zi-O Riders, Team Build Den-Liner Crew, Wizard Riders, Zero-Liner Crew, Gaim Riders, Sword of Logos, Ghost Riders Decade Riders, the Artoria trio, Kamen Rider Zero One and Chaldea looks on.

"Sir Bedivere. And you mask men…"

"We don't need backup; the plan was to leave this to us."

"Yeah, there's no need to interfere, Kouta-san!" Ryugen agreed.

"Fearing the King's punishment, I thought you five had fled."

"Indeed, we had. We ran away, but now we return, to defeat you and the Lion King." They push him back as Bedivere salutes in his chest declaring, "That is my duty!"

"And we're not backing down, cause the ending is for us to decide!"

They then noticed a sandstorm brewing as bells ring with King Hassan who was alongside Oma Zi-O saying, "Thy scream, filled with determination… I heard it clearly."

"And I see you have made that decision."

They turn and saw King Hassan, "The Old Man of the Mountain. and The Future Tokiwa."

"The Wandering Knight… Thou hast shown thy determination. Go where thou must go." He then blacks out the scenery.

"Where is this, place? Who the hell are you two?"

"Look at the sky, arrogant Knight. Dost, thou see the Sun above thy head?" We then saw that they are in a bloodied battlefield field with swords. with him confronting King Hassan and Oma Zi-O.

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.

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.

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

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

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

Ritsuka POV

Inside the Holy City, Holy Land

Year 1273

We then cut into the meeting room with Agravain saying, "What? Lancelot?"

"Yes, He's no longer a Knight of the Holy City. He's currently in battle with Gawain."

This caused Agravain to slam a wall, "That scoundrel… Again! Again!"

"Didn't you see it coming?" Mordred said to him as she sighed, "Alright then, leave it to me. I'm going to kill him."

"There's no need."

"Huh? Are you going to abandon Gawain?"

"Your and Tristan's mission is just to stay alert. They will not be able to pass the gates of the Holy City."

"Excuse me. We have detected an unusual object in the sky, full of magical energy."

"What did you say?"

Outside the Holy city, Holy Land

Year 1273

Back at the battleground, which is now covered in a sandstorm, the heroes are still trying to breach the gate. With Lancelot, Garren and Zangetsu Shin still trying to destroy it.

"So that didn't work either."

"Bedi!" Ritsuka called out.

"If we continue like this, we won't succeed. Our risks are too dire."

"Yeah, we need a new strategy." Build agreed.

"Your assessment is correct, Kiryu-san." Sherlock agreed.

"But the Old Man of the Mountain and the Future Tokiwa has stopped Gawain. This is our chance."

"No… We should retreat. Opening that door is nigh impossible."

"Yes… We'll only suffer more losses." Zi-O agreed.

"But…"

"I agree." They look in the direction of the voice and it was Nitocris stepping out of a portal with a box.

"Nitocris-san?"

"What are you doing here?" Tsukuyomi asked.

"Tell the soldiers at the gate to stand down. Take this." She then throws the box to Ritsuka.

"" Take this?"" Ritsuka then caught it.

"What is this?"

Nitocris smiled as she returned to the portal. And then thunders roar and the clouds disappeared to show Ozymandias' floating palace.

"So that pharaoh finally reconsiders, huh…" Baron smiled.

"Yes, he is Kaito…" Marika agreed.

On the Palace, Holy land

Year 1273

As we go inside, we saw Nitocris appear saying, "Pharaoh, the delivery has been completed successfully."

"A delivery of mine? What are you talking about? I just told you to throw it out because it bothered me." Ozymandias said reminding Nitocris.

"Yes, I do apologize."

"It seems that by looking to the future so much, I lost sight of myself. I locked myself up without even trying to fight. It's not like me. I remember now! I am the one who rules over all! That means I'm an enemy of the world!"

OPEN THE EYE OF THE GREAT SANCTUARY-

In the Holy City, Holy lands

Year 1273

OPENING THE PYRAMID! ACTIVATING THE BULB CHARGE!

START THE CHARGE OF MAGICAL ENERGY.

HEAVENLY GODS BASK IN MY GLORY! ACCEPT THE PUNISHMENT OF THE PHARAOH!

OBSERVE! MERYAMEN! (メルヤメヌ)

The palace then fired a beam which destroyed the gates, meanwhile, the heroes opened the box. Inside was the Holy Grail, "The Holy Grail!"

"It seems that the Sun King had a change of heart."

"Thank you, King Ozymandias."

"I agree on that, thanks for the help, Pharaoh boy." Den-O smiled.

Mash then puts the Grail in the shield as it disappears, "Holy Grail recovered successfully, Senpai, Tokiwa-san."

"Normally, after recovering it, the Era should return to normal, but… it seems that it won't work like that."

"Not until we defeat the Lion King."

"Yeah, you're right about that!" Den-O smirked.

Inside the City, Holy Land

Year 1273

As they went inside, they saw Agravain's Knight blocking their way with one of them charging only for Build and Da Vinci blocking them as they are joined by Yuri and Sophia who are now transformed into Kamen Riders Saikou and Calibur which are a star and purple Dragon themed Kamen Riders. As well as Zeronos and New Den-O.

"Agravain's Knights with mad enhancement!"

"How Awful... To think that he would curse his own comrades…" Calibur muttered.

"That's going a little too far..." Zeronos agreed.

"We'll charge through!"

"Yes!"

"Right!"

"ikuze, ikuze, ikuze!"

They then started to fight the Knights, with Da Vinci and Build blocking their path, "We won't let you get pass us!"

"Yes, better prepare for a beatdown…" Build smiled. As they punched the Knights.

"Da Vinci!" Ritsuka shouted.

"Sento!" Cross-Z also joined.

"Go ahead Fujimaru! Tokiwa! We'll stall them as long as we can! Go now!"

"But…"

"Don't worry, playing dead was enough once."

"And besides we told you we're hard to kill, right?"

"Sir Bedivere, Kouta Kazuraba, Shinji Kido, Touma Kamiyama and Kazuma Kenzaki can you five take care of the rest?" Da Vinci asks Bedivere and the five Riders.

"Yes, leave it to us."

"Let's go, Fujimaru, Lady, and Tokiwa."

"Yes…"

"Understood." They then started running.
