Zeoticus

Tiberius was standing on the shore of Minami Iwo Jima. He wore his Scorpion Gang Boss outfit and used his sword as a transfigured cane. Walking to the wards that hid Mahoutokoro School of Magic from the muggle world, Tiberius introduced himself and was allowed inside.

Once inside, he was led into a pagoda and taken to the headmaster's office, where he waited for a few hours.

"Lord Emrys. Please forgive me for the long wait time. Your visit was so impromptu. I was wrapped up in affairs I could not postpone." the Headmaster of Mahoutokoro spoke as he entered his office.

"Forgive me for just popping up. I just wanted to have a moment of your time. Nothing too important." Tiberius replied

"What would you like to discuss?" asked the Headmaster.

"The barriers in the arena. They aren't composed of wards, and when they were attacked, magic circles shone underneath our feet. Every country has its secrets, so I pushed it aside. And then I overheard some students talking. What caught my attention was that the students referred to the barriers as Devil Magic. Not yokai magic. At first, I thought I was just a foreigner and didn't understand. But after listening around on campus and the use of a translation charm. I figured a couple of things out…"

"And what did you figure out?"

"That my ancestor Merlin Emrys and Merlin Ambrosius are one and the same. Many people in Europe thought him to be a recluse, but the truth is he was traveling the world and at some point came to Japan. And reading a journal around this time, Merlin talks about the bastard son of King Arthur and his sister Morgana Le Fay. Though, he didn't stop there. Because he brought such holy blood here, he was paid a personal visit from a man named Zeoticus Gremory Merlin believed him to be a real devil and learned new magic from him. They became friends. I need to summon Zeaticus. I figured out that many of your students summon devils for magical aid. I discover this is a recruitment house for an association called Golden Dawn. And I've been having people gather information on them. Are you following?"

The headmaster nodded

"Good. I'm not here to cause problems. I just want to talk to Zeoticus. I don't know how much power that will take, that's why I am here" Tiberius explained.

Tiberius had no idea what to expect. When he first heard about Devils, it triggered a very distant memory. Unsure of how to act, he gathered information that led him to his Vault. In times of needed information, the self-organization enchantment came in handy. The book he needed flew to his hands and he read all about Merlin's time in Japan. Raising the Pendragon bastard and helping him rebuild the House of Pendragon. The arrival of Zeoticus and the research of devil magic, and his run-in with Azazel the fallen angel.

Azazel told him about Sacred Gears and requested his help in the research, Merlin refused and eventually invented a form of magic that could be studied and learned by even humans -Japan's greatest secret. The more Tiberius read the more it clicked.

Flashes of memories came to him. He took memory potions and used a pensive to sort his thoughts. In the end, he realized that somehow a smaller dimension bled into his current dimension. It's something that must have happened when Merlin saved his life and sent him to the wizarding world.

Tiberius now wanted confirmation. He didn't plan to do too much with DxD. But he would feel better verifying its presence so that he wouldn't be caught off guard. DxD or Highschool DxD is an old-world story from his past life. Before living stories of legends and rediscovering magic and adventure, humans created stories of magic and adventure with DxD being one the best stories around.

"I can summon Zeoticus. I have a one-time summoning sheet. How much is worth to you?" asked the Headmaster.

"Just put a price on it." said Tiberius.

The headmaster squinted, "500,000 galleons."

"Swear a magical oath you'll honor this sale."

The Headmaster retrieved his wand and swore an oath. Tiberius then wrote a banknote and traded it for the summoning slip. The Headmaster gawked over the banknote and Tiberius just stared at the man. He clears his throat loudly to regain the Headmaster's attention.

"So, are you going to tell me how to use it?" Asked Tiberius.

The headmaster looked a little embarrassed then gave him a quick tutorial.

"Thank you," said Tiberius.

He was then invited to stay for a while. Tiberius agreed and then decided to push the limit. He asked if he could also conduct the summoning there. Much to his surprise, Mahoutokoro had a summoning building for that specific purpose.

Taking his time to eat a meal and scout for talent. Tiberius eventually made his way to the summoning building. It was a nice place, it resembles that of the Buddhist temple Kiyomizu-Dera. Once he entered he couldn't take his eyes away from the walls covered in many types of Solomonic seals. It was the first time he had seen them since coming to this world. Further in was a carving on the wall depicting the biblical great war and the first and second fall of the angels.

The building was sectioned into many rooms for privacy. Tiberius had to pay top galleon to get the room recommended for such a high-profile summoning. Once inside, he waved his wand to clean the place and began to put up privacy wards.

In the middle of the room, Tiberius put the summoning sheet on the floor. Adding some blood to it, he then expressed his desire for an audience. Tiberius thought the Headmaster had bullshited him. When had a summoning been so easy? A few moments later the building shook, a great crimson magic circle appeared on the floor. It shined so bright that Tiberius had to cover his eyes for protection.

The light was soon replaced by a crimson-haired man, he looked to be in his 30's. He had a regal appearance. "Do you know the price for summoning a Duke?" Zeoticus asked.

"No, but whatever it is, the Headmaster of Mahoutokoro is paying. That snake bastard." Tiberius replied.

"It has to be paid by the summoner. It's anything of my choosing. I'll tell you the price once the deal has concluded. Why have you summoned me, Sorcerer?"

"You knew my forefather. You taught him devil magic -Merlin Ambrosius."

"Ahh, I see it now. And the blood of that witch, Morgana Le Fay, I wasn't aware the two of them had a child, being that he killed her and all." Zeoticus laughed.

Tiberius knew his existence was an anomaly as Merlin had already explained that he never had a relationship with Morgana Le Fay in this world.

"Merlin was a good friend of mine. Azazel's too, he followed the boy all the time in an attempt to recruit him. Merlin had no interest though. He was satisfied with his life…" Zeoticus began to think back to all those years ago.

"What can I do for you son of Merlin?" Zeoticus asked.

" I want knowledge about whatever I desire." Tiberius replied.

"Simple enough, and when my daughter takes her territory you will be her adviser. Deal?"

"No, toss in a meeting with Azazel and then we'll have a deal," said Tiberius.

"Done." Zeoticus conjured a contract, "Sign in blood" he said

Tiberius ran his thumb down his index finger and used magic to draw blood. He bleeds onto the contract and used a quill to Elegantly sign the contract with his full name and titles.

Zeoticus looked pleased. "Come, let's meet my daughter."

Sometime later, Tiberius stood in the underworld. The amount of demonic energy that breached his body was intoxicatingly euphoric. His cock hardened and grew in size. It began to hurt. He suddenly felt a heavy hand slammed onto his shoulder. The hand blocked the demonic energy from entering his body and bottle the energy in his magic core.

"That should go down in a bit." Zeotices gesture to Tiberius's erection. "Do you have a magical bank pouch?"

"Y-yes" Tiberius replied with a heavy breath.

"Merlin was the only human known that could assimilate with demonic energy. And I also know he recorded everything. Maybe you can find it and practice, as you will be spending a lot of time here and I can't always protect you. The only alternative is to become a devil. "

"I-I'll find...it" his loins are extremely sensitive, it sent waves through his body every time he moved. "You mind if we wait a moment first?"

Zeoticus chuckled and teleported the two of them to a room in his mansion. Once Zeoticus left, Tiberius stripped naked. His cock was now two times bigger than it usually was when he got an erection. And his tip was now soaked in his never-ending stream of precum.

He then thought it would be smart if he exhausted himself to shorten his recovery time. But when he gripped his shaft he shot ropes of thick white semen all over the linens. The next time he fought the release and lasted longer. Each round lasted longer and longer. But his cock hasn't softened in the slightest. He went on for two and a half hours until he finally went limp and shrunk.

He laid there for a while and realized that 12.7 centimeters was as small as it was going to get from that point on. He didn't know whether to worry or be happy. When he finally got up, a young maid entered the room beat red. "I've come to clean, Master Emrys."

"You may need some help. As you can see, I may have gotten a bit carried away." Tiberius replied.

"I'm more than capable of handling it myself, Master Emrys, but first I must take care of you. Please sit down."

He did as she said, she then cleaned his manhood and applied a cream. A cool sensation washed over him.

"The first, Master Emrys was the same, though he didn't last as long nor did he cum as much as you," she said quietly.

"What is your name?" Tiberius asked.

"Serena, I'm a servant of the House of Emrys, Though it is called Ambrosius in the Underworld. And I stay in the Gremory House as there hasn't been a successor to the Emrys House in centuries. I was a commoner, a low-ranking devil when Lord Zeoticus gave me to Master Merlin. I had no choice but to obey. I looked after the Emrys Estate here. But when Lord Zeoticus heard of the master's death and no successor was named, I was brought back here and the Emrys Estate was sealed." Serena explained.

"Hmm, how old are you? You look around 23 but as you said, you're a devil," said Tiberius.

"900 years old, Master Emrys" Serena replied.

"Hmm, well thank you for the help. Clean this place up and have your things packed when I return." Tiberius then dressed in the clothes that Serena brought him before taking his leave.

After half an hour of being lost, Tiberius finally found Zeoticus in the garden. He was reading as a couple of kids were playing.

"I see you have recovered," said Zeoticus.

"Nicely." Tiberius replied, " Forgive me if you take offense, but I have many things planned in the mortal world. Can we complete our deal now?"

"Of course, Rias! Come here, darling" Zeoticus called out.

A girl that looked about 10 years old skipped over to Zeoticus, and a raven-haired girl followed close behind. "Yes, Daddy?"

"This will be your adviser when you take your first territory? He is a descendant of Merlin, a nobleman in his land. And he will be a very powerful Sorcerer." Zeoticus explained.

"But Akeno is my Queen already," Rias replied.

"Haha no, he will not join your peerage. He is your adviser. Every King has an adviser. Merlin was mine." said Zeoticus.

"Duke, may I ask, when will she take her territory?" asked Tiberius.

"She is 25 now. In about 15 years she and Akeno will physically appear 17/18 years of age. It's the way devils mature. It's why I'm over a thousand and look like a young man. How she looks when she takes her territory will be her appearance for centuries to come. I would call us immortal, but we can die, not of old age, but we can die."

Rias looked at Tiberius and walked to him, she offered her hand and said, "I'm Rias Gremory, Please take care of me when the time comes."

Tiberius shook her hand, "I'll do everything in power to assure your success, Lady Gremory. As long as your father upholds his end of the deal."

Ras smiled and ran off with her Queen Akeno giggling all the way. "So, is Akeno a devil as well. How old?"

"Hmm, she's complicated, her father is a Fallen Angel, and her mother a human priestess. The first Nephilim in centuries. Thankfully she isn't a giant. She still ages like a Nephilim and holds immense power. She's currently 18 years old. She grows faster than us but not as fast as humans. Now, what makes it complicated is the fact that she's now half Devil, half Fallen Angel."

"Which further slows her growth, but how did she turn into a devil. I remember you saying something like that when we arrived."

Due to the deal, Zeoticus had to give Tiberius knowledge of anything he desired. This also meant Zeoticus couldn't lie as that would be giving Tiberius false knowledge.

"It's best that we start from the beginning. Some of it you may know already and some of this may be new." Zeoticus gestured for Tiberius to take a seat. He then placed his hand on both sides of Tiberius' head. "Breath nice and deep. Allow the knowledge to enter your mind"

Tiberius exhaled, and images entered his mind, The first fall of Lucifer, his rule of the underworld, the second fall of the angles and Azazel taking his reign, The Great war of the three factions, the battle of the two heavenly dragons and the creation of the sacred gears, The end of the war with the death of the faction leaders and God, The restructuring of the underworld. And the Rise of Gremory, the birth of his son Sirzechs and his childhood friend Ajuka, The civil war of the underworld, the new regime, and the creation of the evil pieces. Zeoticus then gave him the rest of the history even the smallest of events leading up to that current moment.

When it was over, Tiberius drank a couple of memory potions to organize his thought.

"How interesting. A world without God. Imbalance and impressionable. That's why Akeno isn't a giant, the divine quality that would have made her a monster is diminishing because of God's death. Her father tried to hide her and the Fallen Angels tried to kill her as she was proof that good is dead. A high-class secret kept by all three factions." Tiberius spoke of his understanding of the situation. " Then your daughter saves her and creates something even more heretical, Half devil, half angel."

Zeoticus sighs. "The more small happenings like Akeno occur, the world will soon discover the truth. Forget about humans falling apart. The pagan gods will take the opportunity to reestablish the pantheons around the world. Naturally, that will lead to wars."

"I will not share this knowledge with anyone… I met a servant, Serena. She says she serves my house. Can I take her?" Tiberius asked.

"Did you want her before or after you learned of the evil pieces?"

"Before, her things should actually be packed by now. What can you tell me about her?"

"I think that's a conversation you'd better have with her."

"No, I'm asking you. A Duke doesn't just hand over a devil to serve a sorcerer, especially when the race is going extinct. At least tell me, why her?"

Zeotcus sighed "She is… defected. Though she has evil pieces because of the law and she has decent enough power to spawn three mutated pieces. She is still a low-class devil due to her inability to reproduce."

"And why can't she?"

"She… has both male and female parts. She's actually an Undesirable, It's the only reason I was able to do what I did. Merlin loved the girl. She was 214 when she caught his eye. For his years of service, she was a gift. Two centuries later, he died. No one has touched her since" Zeoticus gave him a wink.

"I'll have to think about that one. But she still comes with me. Can I see the Emrys estate while we wait for Lord Azazel?" Tiberius asked.

A moment later, Serena and Tiberius stood at the gates of the Emrys estate. With his blood, the estate was unsealed and the two walked in. The entire manor was in need of attention. Flourishing his wand, Tiberius repaired the place and it cleaned itself. Now in pristine condition. Tiberius explored. Everything valuable was placed in his vault. The tomes and journals were collected. He took a moment to sigh when he realized he hadn't even started reading Slytherin's tomes yet, nor most of the books that were already in his vault. It would take him years, he had to find a way to shorten that timeframe. After all, knowledge is power.

The estate was virtually stripped clean. Serena and Tiberius made their way back to the Gremory estate. Waiting for them was the Fallen Angel Azazel. He looked exactly as he was described in the stories as Tiberius had never seen the anime. Tiberius was sure that some kind of cosmic event happened to merge the worlds. It kind of worried him.

'What other worlds made their way into this world?' he thought, 'In just a brief moment of connection, two worlds had merged that he knew of. Just with DxD and its concept of the universe, I can already see a chaotic future of skewed reality and absurd reason.'

"Ahh, you look just like him! The hair! The draconic eyes! Though Merlin was a white man and you are far from it. Your skin is flawless like his. And that body, the height, the muscles, a warrior's stature!" Azazel spoke his praise and Serena stared at Tiberius with hot pink cheeks. Her skirt slowly began to tent.

"Excuse me, Master Emrys. I have some last-minute duties to attend to" she said.

Tiberius nodded and she scurried away

"And God be damned, you have the same effect on Serena!" Azazel laughed and Zeoticus chuckled.

Azazel reached over to Tiberius and led him into a seat. "I have to ask, did he write about me? Is that why you asked for a meeting?"

Tiberius couldn't help but laugh, "Yes, and though he considered you a great friend. That's not why I asked for you. I want to know if you succeeded in that project of yours?"

Zeoticus raised an eyebrow. Azazel side-eyed him and then looked to Tiberius, "I can find them. Merlin adjusted a few things for me and it was smooth sailing from that point on."

Tiberius nodded, "I've made a deal to be Rias Gremory's adviser. As long as it does not conflict with that, we can make a deal. I'd like to use your method to find a few myself."

Azazel smiled, "There is something you can do for me, it's not long-term." Azazel rose from his chair. "Come with me" he offered his hand

"Duke, could you tell Serena that I'll be back for her in a bit?" Tiberius asked.

Zeoticus nodded and shooed Tiberius away and he soon vanished with Azazel.

In a tall black citadel. Tiberius was given a tour of Azazel's workshop. Gadgets, books, and a whole lot of stuff that Tiberius couldn't make out. It was a creator's workshop and only the creator could make sense of the place. Azazel led him to a table that had a single crystal-like ball on a metal stand.

"What is it?" Tiberius asked.

"You're a Dragon Lord. Look closer" Azazel smiled with excitement.

Tiberius moved closer and focused. The orb thrummed and Tiberius backed away.

"A Dragon?" he asked.

"Yes, it is. The soul of a dragon, therefore, its power. I've made incredible progress since Merlin's death. I can find many Sacred Gears and I have. I've studied them and this is the fruit of my efforts, Down Fall Dragon Spear. It's a power source now, but it will be incredible when I'm finished. It houses the soul of the Dragon King, Fafnir...

He's unruly and I need you to tame him and bond him to me. I know you can. Merlin saved me once by controlling the Vanishing Dragon, Albion. He forced the dragon into submission long enough for me to escape."

"That's it. And then you'll teach me how to track Sacred Gears?" Tiberius asked.

"I swear it," Azazel replied without hesitation and an expecting grin.

Tiberius sighed and faced the dragon "O 'Fafnir! ufuddhau i'm barn! Cyflwyno i General Azazel. Ef bellach yw eich meistr!"

The dragon soul roared and replied "Gwneir eich ewyllys, Arglwydd Grundriss"

Azazel looked shocked as he heard Fafnir's words and a surge of power wash over him, "I wasn't expecting this..."

"What happened?"

"I can feel his power coursing through me. Like I can use the power of Fafnir without the need of the Sacred Gear. I doubt it would manifest like the gear I had in mind. But that can be remedied by simply completing the Sacred Gear." Azazel was in a state of shock. He then started to sift around for his journal and began to scribble away once he found it.

"General?" Tiberius asked. Azazel reached over to another table and threw a book at Tiberius.

Tiberius looked through the book "How am I to read this?" he asked.

Azazel paused with an embarrassed smile.

"Apologize. Here" Azazel touched his forehead and a spell entered his mind. "Now, I'll send you back."

Azazel snapped and Tiberius was teleported back to the Gremory Manor…

X

Tiberius spent some more time at the Gremory estate getting to know Rias and Akeno. He eventually met Sirzechs Lucifer. But soon, Tiberius took his leave with Serena and left the underworld. Before he left, Zeoticus imprinted a seal on Tiberius, giving him access to the Gremory Territory in the Underworld.

"What shall we do now, Master Emrys?" Serena asked.

"We head to Scandinavia to see a friend and then back home to meet the family and plan for my party" Tiberius replied.

"Allow me to take us, Master Emrys" Serena held on to his arm, and the next moment they were in Scandinavia. Giving her specific coordinates. She took them to the Durmstrang and the two waited at the wards.

"Serena, I've been meaning to ask. Do you have a Peerage?"

"No, Master. The evil species were created when Master Merlin was away. And he died before he found out. Being without a master, I couldn't reincarnate any devils as no one could give me permission. When it comes to servants, our Peerages are our master's servants as well. They represent the house and because of this, a servant can not add to their peerage without permission." Serena explained.

"Hmm. Makes sense. So, first rule, your identity as a devil will remain a secret. And no skirts until you can control yourself." said Tiberius.

Serena blushed and put her head down "I-I only get excited around you, Master. I will try to behave myself." she clutched the bottom of her skirt.

Tiberius shook his head, "Well, I feel special. Thank you, Serena. But these people have never encountered a special woman like you. And I will hate to see them dead for what they may try to do."

Once the inside Durmstrang. Tiberius and Krum went to his room.

"Emrys, my friend. What brings you here?" He asked in a thick Bulgarian accent.

"The Triwizard tournament. Is it really happening?" Tiberius asked.

"Ahh, it's what Karkaroff has said. I know we will be there. But many other schools are going through a raffle. Between us. I hope it's Castlebroxo. That Melina Vera is a dangerously sexy woman."

" I heard she kicked your arse." Tiberius teased.

"Haha, I heard she fought you to draw?" Krum asked.

"I have knowledge and skill. I just need more practice. The wand is a bit restricting at times." Tiberius explained.

"It's why Ugadou always wins." said Krum with annoyance.

"Aye. So, I heard something interesting while I was in America. Grindelwald's wand wasn't Grindelwald's wand. Now Dumbledore uses Grindelwald's faux wand. What's the story? I know you know it, Durmstrang boy."

"Yes. Durmstrang was the command base for Grindelwald. All I know is that Grindelwald stole the wand from the wandmaker, Mykew Gregorovitch. It was a powerful thing. Many thought he was unbeatable with that wand. Until Dumbledore stopped him." said Krum.

" I guess I'll have to talk to the old man. And I'll see you at the Triwizard tournament."

"I look forward to it, friend." Krum replied with a smile as he and Tiberius locked forearms.

"Oh, and the tournament is between Drumstrang, Beauxbaton, and Hogwarts. That's part of the reason I came here. I wanted to see if Durmstrang was serious, or if this was just another failed project of the Ministry."
