Ryuhei observed the construction of the inhabitants, it had only been almost a week since they had come to this world but their adaptability was impressive. Currently, Ryuhei's 'country' is being divided into different regions. At its center is inhabited by almost every race and tribe in the world. Here is where all races and species can live in harmony.

The residents here are all from Totto Land. They include humans, Fishman, merfos, long-armed humans, long-legged humans, dwarves, three-eyed humans, along with several hybrids of different races.

To the south is the settlement of migrants from Wano and Zou . There are forests and vast plains here. They are in charge of providing future agriculture.

In the East is the settlement of Fishman, they will be responsible for providing seafood in the future.

In the north is the settlement of the migrants from Dressrosa, in addition, this is also the headquarters of the Adventurer Guild. An organization founded by Ryuhei. However, for now, Ryuhei has succeeded in pushing the management of the Guild to Whitebeard.

The quest of the Adventurer Guild was very simple, this was the Adventurer's headquarters. Most Adventurers will receive basic training in Haki and Roku Shiki in the One Piece world before they can accept quests in this world. Most of their missions will explore the continents and especially the black continent. Each mission will have different difficulty, depending on the rank and strength of each adventurer.

"Damn… How did he convince Rayleigh to be a teacher here?" Whitebeard mumbled as he read the various papers. It was clear that Whitebeard wanted to retire to enjoy life with his children, but Ryuhei "forced" him to do the job.

"Come on Pops… It's quite a fun job." Marco smiled wryly, even he was entangled in this work.

"Marco is right, Pops… The job isn't bad at all." Vista said with a cheerful voice, now he has become a sword instructor for novice adventurers.

Then Whitebeard took out Den Den mushi and called someone.

"…Newgate." Bigmom's voice came from the other end of the line.

"Linlin… Are you used to your new job?" Whitebeard said.

"You mean managing the guild and training those weaklings?" Big Mom replied.

" …Yes."

"I let my kids do it. "

"So have you really given up on world domination?"

"… Mamamama… Right now I can only live peacefully… I was almost killed by that monster."

The two then continued to chat with each other about their new jobs. The two were once the emperors of the sea… However, their jobs now are no different from babysitters.

Ryuhei stood at the top and watched Luffy's group training… More precisely, the process of Garp beating them.

"Luffy, is that what you call punching?. Put more force into your arms." Garp yelled and punched Luffy in the head, who immediately complained because Garp was always punching his head .Saeko was fencing Zoro under Mihawk's watch. Ryuhei looked at the last of the trio and him. immediately wanted to punch Sanji in the face when he saw the shirt he was wearing. Sanji's t-shirt is printed with Ryuhey's face. However, Ryuhei quickly calmed down and continued to observe things. Right now, Sanji is practicing the martial arts that Ryuhei taught him, which includes Capoeira and taekwondo. In addition, Sanji also expressed his desire to become a priest to evangelize his faith after he found it All Blue.

While Luffy, Zoro and Sanji were training here, Nami and the others were elsewhere where they trained to strengthen their strengths.

Currently, Luffy's group is training in Utopia. They will spend about a year here training and becoming Adventurers to gain more experience before they return to the One Piece world.

While observing what was going on in the training ground, Ryuhei also noticed someone's eyes and looked at the stranger.

The observer Ryuhei was a slender young man of relatively tall height. He wears a northern-style fur hat, which is white and has a pattern of spots along the bottom and on the tip. The one who was quietly observing Ryuhei was none other than Trafalgar Law, somehow Law and the other members of his crew succeeded in migrating to Utopia.

' If I remember correctly, that was Trafalgar Law… ' Was what Ryuhei thought before he lost interest in Law. He knows about Doflamingo and Law's relationship however he is not too concerned about this.

Ryuhei landed on the training ground, Luffy immediately noticed this and raised his hand to greet him.

"Yo Ryuhei." Luffy let out a trademark smile.

"Yo." Ryuhei greeted back, Zoro and Sanji also stopped when Ryuhei appeared.

"What are you doing here?" Luffy asked.

"Nothing much… I was just walking around." Ryuhei said. He then looked towards Zoro and Sanji.

"Hey, how about practicing with us? We want to test our training results." Zoro said.

"Oh, are you sure?" Ryuhei said with an amused voice.

"We know we still can't compare to you, but I still want to check our distance." Zoro said, Luffy and Sanji stopped as well and went into battle stance.

"Oh… Okay… I don't mind having a little fight." Ryuhei said while picking up a wooden stick.

"Can I participate in this match? ."

Ryuhei and the others looked towards the voice, it was none other than Law. He walked over while placing the Nodachi Kikoku sword on his shoulder.

"Oh… Are you tired of peeping at me? Trafalgar Law."

"…"

"Whatever… Swim in here." Ryuhei began to coat Haki over the stick he had just picked up. At the same time, Zoro and the others also entered a battle stance. They also began to coat their arms, legs, and swords with Haki.

"Santoryu…" Zoro began to crouch while holding a katana in his mouth.

"Gear Second." Luffy's body started turning red and emitting steam.

"Diable Jambe." Sanji lifted his right leg, and at the same time a flame started to erupt from his leg.

"Rooms." Law creates a blue spherical space.

"Very good preparation… Now prepare to receive my ultimate move… I will name it Bonk." Ryuhei said as he also took a stance and twirled the wooden stick.

"There's no denying that you've made a lot of progress." Ryuhei walked while the large slash in front of his chest was starting to heal. Behind him were the trio from the Straw Hat Pirates and Law were breathing because they had been repeatedly beaten by Ryuhei.

Law lay there while clutching his hand, vowing that he would have to be stronger in the future to defeat Doflamingo and revive Rosinante.

When Ryuhei went out to the training ground, he noticed Nami and Chopper.

"Chopper, come heal them." Ryuhei said to Chopper while pointing towards the people lying on the ground.

"Woooo, Luffy, Sanji, Zoro… What happened?" Chopper shouted while running towards the trio.

"Haizzzz, what are they so stupid about? Thank you for being gentle with them." Nami said while sighing.

"Well, they didn't do anything wrong. They just want to be stronger to protect those around them." Ryuhei said.

"…I know… But there's no denying that sometimes they do without thinking about the consequences." Nami said, then she continued to ask.

"So when will you return to your world?"

" …Tomorrow ."

"So will you be able to return to my world in the future?" Nami asked.

"I'm not sure… but maybe there is… Currently I ate a devil fruit that helped me create this world. This world is basically the intermediate world between Rias world and your world. Theoretically, I can now travel to these worlds easily." Ryuhei said causing Nami to let out a sigh of relief.

"Haha… Don't tell me you already like me."

"No way… I just want to go to another world to explore everything… At least after I fulfill my dream." Nami said hastily.

"Well, I was just teasing you." Ryuhei said then he placed his hand on Nami's head before leaving.

The next day, was also the day that Ryuhei returned to the DxD world. Ryuhei and the others gathered together. They consist of two groups, the first group is Rias, Akeno, Kuroka, Koneko, Boa Hancock, Robin, Albedo, Irene, Ei-chan, Nilou-chan. The second group are members of Rias' peerage and Ryuhei's peerage, they include Mihawk, Doflamingo, Yamato, Baby 5 (who was somehow able to join Ryuhei's peerage as a pawn because her diverse fighting abilities.) As for Rias' peerage, there are Carrot, Katakuri and Black Maria.

Originally, Ryuhei was going to take Bonney and a few others with them, but they still had some work to do in Utopia so they decided to come to his world in the future.

"Now you are about to enter a different world, a world that has a different culture and technology than yours. Please follow the instructions of Rias and the others." Ryuhei told the people in the One Piece world.

"Come on… Don't look at us like we're a bunch of trouble.ZZZZZZ." Garp said happily before he suddenly fell asleep.

"…"

"Garp-san is right… There's no way we can cause trouble. Just believe in us, Ryuhei-sama." Yamato said.

"You're the one I'm most worried about, Yamato." Ryuhei said.

"…"

"Mihawk, always keep them in your sight."

"Don't worry, I'll keep an eye on them." Mihawk replied. He is always the calmest person in Ryuhei's peerage. Somehow, Garp and Yamato's stupidity didn't affect Mihawk, currently Mihawk's IQ hasn't dropped even a bit.

"Ryuhei-sama, rest assured. I certainly won't cause trouble… Though I'm a bit curious about Hatsune Miku." Doflamingo said . Make Ryuhei regretted showing the clown an anime and listening to the virtual singer sing. At first he thought that Doflamingo was just curious about new things… But somehow Doflamingo gradually became an Otaku.

After taking care of everything, Ryuhei walked towards Saeko, who looked extremely depressed because she was about to leave.

"Come on… Don't make that face…" Ryuhei said as he pulled her into his arms. "I don't want to see your sad face."

"…But… it's sad to have to leave you." Saeko said.

"But aren't we still seeing each other every day thanks to the group chat?" Ryuhei whispered in her ear.

"But… only 4 hours a day…"

"Haizzz… Think positively… There are so many women by my side… but you have four hours to do what you want with my body… Isn't that great?." Saeko seemed to understand something, her eyes seemed to say 'Oh, that's right.' Then the two shared a deep kiss before they began to teleport back to their worlds.

(Author: There's still a lot we haven't discovered in One Piece. Shanks, Im-sama…and many more that haven't been mentioned in this Fanfic…Perhaps in the future.)

In the DxD world, Ryuhei opened his eyes and found a forest in front of him… No, it was too few trees to be considered a forest. In the distance was a modern town and Ryuhei immediately realized where he was. Currently he is on the hill behind Kuoh town.

"So this is your world, Ryuhei…" Garp muttered while looking at everything.

"Ohhhh… Look at the buildings…" Yamato said excitedly.

"Where is Hatsune Miku? ."

"Ara ara…The architecture of the buildings is interesting."

"There's something flying in the sky… Can I attack it?." Katakuri said.

" No… Don't do that, it's just a means of transportation. It's called an airplane."

"Ryuhei-sama… Wouldn't it be strange for ordinary people to see us." Black Maria approached and poked Ryuhei's cheek with her large finger.

"You're right… But stop poking my cheeks." Ryuhei said, what Black Maria said is very true. Normal people would surely faint from fear when they see them Garp, Doflamingo, Katakuri and finally Black Maria. Their body size is definitely huge.

"Fufufu…Then I'll poke another part of your body." Black Maria said while licking her lips.

"Tch…Stop acting like that, bitch ." said Albedo.

Ryuhei gradually felt a headache in front of this group of people. He immediately teleported all of them into his mansion.And right after that, a large breast hit him right in the face.

"Welcome back , husband ."
