Chapter 1 The Start

Night

Pendragon (Britannia)

Within the chamber of a royal prince had two people entering into a hot make-out session with their tongues battling each other for control. The pair broke their make-out session to grain air and gaze at each other with love in their eyes.

The first is a young man with shady brown/black hair and a purple eye while his left was covered. He had a body of an Olympian summer and soldier, wearing black pants and had no shirt on. This was Julius vi Britannia, the Warlock of the Empire, Leader of the Fenrir Knights, and a member of the Three Holy Swords.

The second was a mature proud woman with pale brown tinted purple hair and green eyes. She had a rose tattoo above her left breast. She wore a see-through white silk robe that underneath wore purple bra and panties. This was Guinevere de Britannia, the first Princess.

Yes both of them are siblings, half-siblings that share the same father.

Julius is the son of Emperor Charles and late Empress Marianne, and older twin brother of Lelouch and older brother of Nunnaly. He had everything he ever wanted and enjoy his life but he witness his mother being killed and sister crippled before his eyes which the assassin attacked him as well. He was saved by his brother, but his left eye was scared and to this very day he covers it to block the pain and power at bare for the time being.

Unlike Lelouch who throw it away, Julius faced his father and asked if he can join the army to seek justice for his mother's murder. Charles allowed this and told his son that his brother and sister are dead due to a bombing in Japan. He was saddened by this news but hold a strong heart and keep going in memory of his mother, brother, and sister. The young man was an Imperial officer, general which he earned the title of Black Prince, and leader of his own military faction.

"You know we can't have much fun tonight," Julius said as he was looking forward to this but sadly no as he was needed for a meeting and was best not to be late.

Guinevere sighed and said, "True as I need to make a few meetings as well and I need my legs to walk around."

"I can carry you." Julius offered with a smirk as his right-hand rubs the fine legs, getting some moans.

"Flatter but let's rest with some play in mind."

"I can handle that."

And with that, the pair rest in their shared bed with grateful moans that could be heard before turning in for the night.

(Next Day)

Time Skip (Throne Room)

In the imperial throne room, we see emperor, Charles zi Britannia himself waiting for three knights to come who are his sons and here they are walking into the throne room.

The first was Julius vi Britannia, the Warlock of the Empire

The second was Charlemagne el Britannia, the White Knight of Justice and Truth

The third was Achilles zi Britannia, Knight of the Round-Knight of Two

Together, they formed the Three Holy Swords and stand before their father, the emperor before taking a kneel but not Julius, not a surprise for the brothers or Charles. He stood up with a smirk on his face, a daring wolf to be sure.

"Hail the 98th Emperor!" Achilles and Charlemagne greeted

Charles raises his hand, stopping the boys and allow them to stand up.

"Still the wolf I see Julius. I thought that the military push that troublesome act aside," Charles said, the statement he knows with a knowing smirk on his face.

Julius just smirks and said, "They did but those fools were mere dogs to a wolf. And I know you have called us here of the matter of Zero, the murder of our brother Clovis."

"Yes, you three are aware that Area 11 is becoming a problem of lately due to actions of groups fighting back and Zero killing a member of the Imperial Family."

The three stood quite on that, knowing the problem of Japan both past and now. Achilles had to help Lana as she took her older brother's death the hardest. All of them have lost more so in Japan years ago but moving on.

"I see. You want the three of us to deal with the terrorist groups and Zero with Cornelia," Charlemagne said, catching on and now what the three are here for now.

"Yes, I want you to make sure Zero doesn't become a big problem and get Area 11 back in order that Clovis fails to do. And yes, Julius, hunting begins," Charles said, getting Julius to smirk on the chase to hunt.

"Very well, Your Highness. We, the knights shall depart right away for Area 11," Charlemagne said, having his brothers agreeing as well.

"All hail Britannia!" The brothers said and were left the room to depart for Japan.

"I will have to get the Fenrir Knights in line and a good number of squads with us, brothers. I will be joining you very shortly at our transport," Julius said, taking his leave to his quarters and office to phone the troopers and get a few things for the trip.

"Very well brother. I shall call our sisters, Cornelia, Euphemia, and tell them of arrival," Charlemagne said, getting a nod from Achilles.

"Agree, brothers. I will meet you two at our transport very shortly," Achilles said, watching his brother leave and go over a few things with his maid.

Achilles thought to himself over a few things. So much have gone by and grateful for that while some not so much but was had good moments. For you see, Achilles is not Britannia by blood but adopted and that's quite a story to go over.

Achilles or rather Naruto Uzumaki-Naimkaze was a member of a family from another world but heavily neglected and abused by his family due to the Toads and fools in believing his siblings to be the chosen ones as they were called and was later disowned for not having high enough charka. They wanted him to be a tool to be used and be sold off to the dogs while brats become heroes. Having enough of it and the bullshit, he left for the forest of death, and somehow found the gate to the C's world that was the bridge to his world to a new one. With nothing to lose he decided to leave with his one true and only friend then blackness overtook them as they fell unconscious with the gate closing.

Naruto woke in a hospital a few weeks later in a new world with nothing but the clothes on his back. His sudden coming to this world brought the attention of Emperor Charles and Empress Marianne who the woman loved to death as her own son. Having found him in a Thought Elevator.

Marianne was able to get through the cold shell and helped Naruto heal as a true mother would for her child while vowing to make sure the fools pay one day for what they have done to him if she could get to his former world.

Charles later adopted the boy seeing himself in him not giving up on life and hold on life to be strong, a powerful drive that shouldn't be wasted and push forward. To make Marianne happy about adopting him and see what this other worlder can do. On that day Naruto dies, Achilles was born and worked hard to get to where he's at but to his lovers and true family he's Naruto by name. To remind himself of how far he's come and who he wants to be.

"My prince, the transport is ready," A female voice spoke, getting Achilles to look at her and smiled.

She was a young woman with long brown hair and light brown eyes. Her hair is straight on one side, but on the other side, it is in a braid. In addition she sports a clip with two circular designs. She wore royal clothes of a maid and mistress of a prince would wear with red lipstick. This was Yakumo Kurama, Achilles' truest friend in life who came to the new world to be with her only friend that treated her like a human being and she to him. Having only Shinobi books sealed on her and the clothes on her back.

"Thank you Yakumo," Achilles said with a smile as he enters the limo with his friend coming in.

Yakumo smiled at the thanks and walk in the limo.

"I made sure your personal things were locked, clothes for the trip, and called the group to have the Knightmares loaded up, Prince Achilles," Yakumo informed.

"Good work, Yakumo, and please no titles as we are friends for a long time," Achilles said, never a fan of the title of prince. He is grateful for it but saw himself as a knight instead and hugged her.

"I will do my best, Achilles," The brown-haired maid said with a smile on her face returning the hug.

Achilles smiled at that and the ride was quiet for the pair but the maid wanted to talk as she is still getting used to long travel.

"You think your sisters would take kindly to you and your brothers' arrival?" Yakumo asked.

Achilles thought for a second on that question and said, "Hard to say now but we will find out together". As he cupped her head and kissed her on the lips passionately with love and affection and held her hand within his as he ended the kiss while using his free hand to let her rest her head on his shoulders.

"Understood," The blushing brown-haired woman meekly said, understanding that and would leave it be for now though wondering if she could get her 'payment' at some point in content silence and a goofy grin on her face. Naughty maid and her books whose to stop her she does her job well, she loves being 'paid' by Naruto, and the best ones are quirky in her mind so sue her if she's a closet pervert. She can show how her nasty mind to Naruto and lovers without broadcasting it plus they love it.

DxD universe world the Underworld.

Sirzechs and Serafall sneeze blowing paper everywhere. 'No! Now I'm stuck here longer and can't see Rias/So-tan and embarrass her like I planned.

Issei sneezing alerting the Kendo Girls. 'WHY NOW?! I'm being attacked by armed booby warriors!' he screams while running off.

Code Geass world.

Soon enough the drive ended and the transport, an airplane for royalty was here with Julius and Charlemagne inside waiting for their brother.

Achilles and Yakumo exited the limo with their things in hand, heading to the plane and get ready for the next adventure, a new one in Japan. This shall be interesting and we will what will happen next. Though to the princes it was clear the maid and prince were romantically if the smeared lipstick and mark on the corner of their mouths said anything, the facts on how he's helping her and her relaxed yet working smile add to it being mutual. Love is love they suppose and they are childhood friends as they are happy with their current lovers so can't judge them one way or another lest they be called out themselves.

Secret Room (Emperor's private room)

"So you are sending them off so soon Charles?"

"Yes as I have a feeling that Achilles would find her much better than anyone else due to their strong feelings."

"Hehehe, bold move, but reasonable one as CC took a liking to little Achilles when he was little and would be interesting to see each other after so long. Julius would be happy to see her but more of sibling bond rather than love like Achilles has for her. Lelouch did annoy her and was more amusement but a friend for sure".

"True, true, very true my dear. I will make sure the plans are in motion very soon while keeping an eye out for my brother making sure he doesn't act recklessly."

"Honestly, I don't why you keep that hobgoblin around, not after what he has done to me, my sons, and daughter."

"*sigh* He is useful but makes no mistake, my love. I will make Victor suffer for what he has done and he will know fear than death. Plus he's immortal so can't kill him now so torture will have to do but he will learn".

"Ohhh, I can't wait for that *yawn* but sadly we will have to end this meeting, for now, my husband. Little Anya needs her rest and my Geass needs a break as well."

"I understand. Sleep well Marianne, my vixen."

"Good night, Charles, my love."
