Section 2:

Return to the Home of the Once and Future King Part 1

3rd POV

Outside the Hyoudou Residence, Kuoh Town, Japan

2018 AD

We then open the scene with Issei shooting lasers at the Wyverns, with Vali and Melusine also joining the fray as they use their superior speed as they tackled many of the Golems and Vampires, with Melusine saying, "Impressive you are just as fast as I am."

"I could say the same to you." Vali smiled; he then saw a beam coming towards them he then stretch out his hand as a voice called out.

DIVIDE!

The Beam then started to shrink as it disappears, he then saw a Wyvern coming towards them, with Melusine slashing it in two, "My that was close."

"Nice save there, Vali Lucifer."

Vali smiled as they continue to fight the Wyverns, meanwhile we saw that the others are also doing their best at fighting the enemy forces. With Arthur, Kiba and Le Fay teaming up with Artoria, Morgan, Aesc and Okita.

"My, I'm impressed with your swordsmanship, as expected from my descendant." Artoria smiled as she slashes a vampire with her Excalibur.

"I'm glad to hear that your majesty." Arthur smiled as he stabs another Vampire.

As for Kiba and Okita are also working together by using Shukuchi to attack the enemies swiftly, with Okita looking at Kiba as she said, "I'm impress to think that you have mastered the Shukuchi well."

"I learn from the best." Kiba smiled as he use Shukuchi to reach a Golem and slashing it.

And as for Morgan, she and Le Fay are throwing spells, with Morgan and Aesc looking at Le Fay with a smile as the former said, "My I must say you are really a genius."

"I'm honored to hear that, Lady Morgan." Le Fay replied.

Aesc giggled as she cast another fire beam at a vampire, "You really took after me, huh?"

Le Fay looks at Aesc as she gets flustered, "Of course… Young Lady Morgan!" Aesc smiled as she release beams of light to destroy a horde of Wyverns.

As the fight continues, Ritsuka then muttered, "Looks like we're going to need some extra muscle!"

Rias looks at him and narrowed her eyes, "What do you mean by that, Fujimaru-san?"

The Mage smiled as he replied, "This…" He then held out his right hand revealing his command seals. He then declared, "BY MY COOMAND SEAL… COME FORTH YAMATO TAKERU AND MIYAMOTO IORI!" As soon as he shouted this Rias and most of the ORC members were caught in surprise as two figures suddenly appear and destroy some of the brotherhoods minions as the dust clear off, they saw the two figures' appearance one was a young man with black hair wearing a dark teal kimono with two swords on his hip and the other was an androgynous person that looks like Artoria but with black hair brown eyes and is wearing a white tunic in her right hand is a kris. This is Miyamoto Iori and Yamato Takeru.

"You called, master?"

"What do you want us to do?"

"Ok, Takeru, Iori help the others now!"

"Yes Master!" The two replied as they start to help the others.

"Umm… Fujimaru-san is that who I think it is?" Rias muttered.

"Yes, Yamato Takeru and Miyamoto Iori, why is there a problem?" Ritsuka narrowed his eyes.

"No, it's nothing!" Rias replied she then looks at Irina and Xenovia as she thought to herself, "I wonder what Zekka would think of this."

Ritsuka then looks at Mash and Gray and said, "You two should go now."

Mash smiled, "Of course Senpai." She summon her shield as Gray readies Add in her scythe form. As they start to fight alongside the others. With Mash and Gray showing off their skills with the former using a mixture of martial arts and shield combat while Gray slices and dices every enemy attacking her.

"My those two are impressive." Xenovia said.

Irina nodded, "I agree Mash and Gray are really good."

Issei seeing this gives out a sigh, "Geez Ritsuka that dirty bastard! How come he is just as popular with the girls as I am."

As time goes on, Ritsuka is now thinking to himself, "How did the brotherhood even know of this place… It shouldn't been impossible for them to get here."

As he continue thinking, he then sense someone coming as he shouted, "EVERYONE BE ON YOUR GUARD! SOMEONE'S COMING!"

This caused the others to look at him, with Issei asking, "WHAT? WHAT DO YOU MEAN, RITSUKA!?" As Ritsuka was about to answer they heard a laugh reminiscent of Wilem Dafoe's Goblin.

"HAHAHAHAHAHAHAHAHA-!"

This caused Ritsuka, Issei and Gasper to widen their eyes as they have watch Spider Man and in Ritsuka's case Spider Man: No Way Home.

They then saw a bomb tumbling towards the three dragons dodged it as it explodes, they then heard a man shouting, "WOW! NICE REFLEXES YOU THREE GOT THERE!"

They then turn to the direction of the voice and there they saw the man with the face of Dafoe and James Franco but now is wearing a red hoodie shirt and has two armblades and is riding a hoverboard.

"What the—Who invited the Green Goblin here?" Issei asked.

Ritsuka was now cautious with him, he then moves forward as he asks, "If I may ask are you the Brotherhood member that is attacking this dimension."

The man laughs as he replied, "What are you an idiot? Of course I am! The name is William Frank, and I am going to be the one that's going to kill ya! Master Of Chaldea!" He then started to try and attack Ritsuka, only for Issei, Melusine and Vali to block the attack.

"Wow nice reaction." William smirked as he grin, "This is going to be fun." He then started to trade blows with the three. Issei tries to punch William only for the latter to catch it while shouting, "Impressive!" He then kicks him only for Vali and Melusine to shoot lasers on his back.

William turns to their direction and tries to kill them with his bombs, with the two White Dragons dodging it and then started to beat the living heck out of William who only laugh it off with Issei doing a kneeing his stomach.

"My you three really are good!" William smiled as he then jumps back to his hoverboard as he looks back at them, "Next time we'll be settling this on Europe!" This caused the European Servants alongside Issei, Vali, the Pendragon Siblings, and Melusine to widen their eyes.

"Hey where do you think you're going?" Mordred shouted.

"Just returning to my base, Ciao!" He then disappears as his hoverboard started to fly away. As his minions are all but destroyed by the other heroes.

"HEY GET BACK HERE!" Issei shouted.

"It's no use, Issei Hyoudou, he's gone." Vali muttered.

Ritsuka nodded, "I agree with Vali here, we need to go back to your house to discuss our next move."

Issei looks at the Master and replied, "I guess so…"

They then reconvened with the others as they go inside the Hyoudou residence again.

Morgan POV

Hours later inside the Hyoudou Residence, Kuoh Town

2018 AD

We then cut to the Hyoudou Residence, as we saw that the heroes are now sitting in the VIP Room. With Ajuka asking, "Are you certain he said that?"

"Yes… This William guy says that he is waiting in Europe… No doubt that he is going to be in either Britain, France, or Greece." Da Vinci muttered.

"So, what are we going to do now?" Rias asked.

Arthur then suggested, "How about we go to my family's estate in England to warn m father?"

"Are you sure?" Vali asked.

"Yes…"

This caused the others to look at each other, with Artoria saying, "If you say so, then that's the plan." She then looks at Morgan and asks the Winter Queen, "is that okay with you, Morgan?"

Morgan looked at her as she sighed, "If you say so…" This caused Sith, Artoria Caster, and Aesc to look at her with worry.

"Okay then let's pick straws on who will come with us…" Issei said.

They then pick straws, and it was decided that the Chaldeans will choose Ritsuka, Mash, the Artoria, Artoria Alter, Artoria Lily, Artoria Caster, Gray, Arcueid, Melusine, Mordred, Jeanne, Achilles, Atalanta, and Okita.

As for the DXD heroes, it will consist of Issei, Vali, Arthur, Le Fay, Rias, Kiba and Xenovia. As they went outside Le Fay is now creating a portal with her saying, "Are you all ready, everyone?"

"Yes, we're ready!"

Le Fay smiled as they went through the portal.

Inside the Pendragon Residence, England, Great Britain.

2018 AD

We then cut to the Residence, where a young back haired maid was now cleaning the rooms as she thought, "I wonder what Arthur and Lady Le Fay are doing?" She then saw a portal opening as she muttered, "What the—Is that a portal?"

As she approached it, the Chaldeans and the DXD Team suddenly came out, with Elaine saying, "Arthur? Lady Le Fay? what are you all doing here? And who are you, people?"

Arthur replied, "Hey Elaine we need to talk with father now!"

"Why? What happened?"

"Please... It's urgent we need to talk to him now!"

Elaine then nodded as she said, "Okay I understand come with me." As they were being led by the maid, Morgan, and Aesc are now feeling a little sad.

"Are you okay." Aesc asks her older self.

"Yes, yes I am…" Morgan replied.

"Are you thinking about "him"?" Aesc asked.

Morgan nodded as if she is saying yes. Aesc then bowed her head her bangs covering her eyes. As they reach the door, Elaine knocks on the door, "Umm… Lord Uther!"

"What is it, Elaine?"

"It's Arthur and Lady Le Fay they are here to speak with you!"

"Oh, I see you can let them in."

Elaine then opens the door to reveal a man that looks a lot like a much older Arthur and is wearing a noble outfit, "Arthur! Le Fay! What are you two doing here?" He hug the two as he turn to the other DXD members and Chaldea, "Oh I see that the other members of DXD are here… But who are those people?"

Ritsuka as now embarrassed at this as he muttered, "Well—"

"Father, can we take this inside." Le Fay said.

"Oh okay…"

They then went inside the dining room, with Issei and Ritsuka explaining the situation as well as introducing Uther to the members of Chaldea. Uther was awed at what he heard as he sad, "Goodness me… That was quite a story to think that a day would come that I will see my ancestors in the flesh."

Artoria, Artori aCaster and Artoria Lily blushed at this comment, however, Uther then look at Morgan, Artoria Alter and Mordred, "But still are you sure we can trust these three."

"Of course, Uther-san" Mash smiled.

"Okay… Now then let's get to the main topic, shall we?"

Meanwhile, in an unknown place

2018 AD

We then go to William who is now smiling as he is now experimenting with his weapons, "Oh boy this is going to be one hell of a plan this will knock the socks off of that Red and White Brat and I will have a hell of a time with them and their bitches."

"HIHIHIHIHAHAHAHAHA!"

Author's Notes:

And that's that. As you can notice I modeled the main villain from Raimiverse Goblin. I'm a big Spider-Man fan and so I wanted a villain that would be a personal nemesis to Issei and Vali especially the latter. So, I design William here to be the antithesis of everything Issei and Vali stood for, unlike Issei who likes boobs and is kind to women. William is a woman hater to the same degree as Shinji Matou. And as for Vali who wants to be strong and cares about his family and his friends. He is a weak coward who will cheat and doesn't care about the brotherhood as a whole.
