The Dragon Emperor

Chapter 8

Dragon and Devil

"This really brought me back…" Natsu said fondly as he sparred with Erza Scarlet, the Scarlet Titania of Alvarez Empire, as she donned herself in her fire resistance armors, an upgraded version of her Entei no Yoroi (Flame Empress Armor) to fight against a powerful fire mage like him. Erza's armors and magical weapons had been upgraded, greatly improved in both offensive and defensive after she became one of Natsu's Spriggan Guards. Erza herself, had also become a lot stronger than she could even imagine, surpassing even the stronger members of the original Spriggan Twelve in all terms.

But as she flew toward him started swinging her sword at her Emperor, she couldn't imagine a possible picture of her winning against Natsu. She slashed and slashed, but no matter how quick she slashed or how much power she put into it, she couldn't land one single hit. It was like he was on a whole new different level. At the end of the war against his brother and Alvarez, Natsu had become insanely powerful, to the point he far surpassed even his brother in his prime, and even Acnologia, a dragon slayer himself. His strength continued to grow even crazier during his years of ruling Alvarez Empire, but whenever she trained with him, Erza was still able to land a couple of hit and forced him into defensive.

However, at the moment, Erza couldn't help but wonder if Natsu was even trying to dodge her attacks, choosing fighting her with pure physical strength instead of with his magic. It was true that she wasn't fighting all out, but Natsu had never had that much easy when he was fighting someone of her level.

To make it even more terrifying for Erza, she believed that he was fighting her with the minimum of his strength.

In one single year of absent, he could defeat Ikusa-Tsunagi, one of the Yakuma Eighteen War Gods, all by himself and defeated Zeref as well as finished Acnologia. In three years at the Emperor of Alvarez, under the guidance of Irene and some of the best mages of the kingdom, he had become so strong that he was hailed at the strongest mage in the history of Earthland, and with one thousand year of travelling around the world, meeting many supernatural beings with extraordinary power… Erza couldn't stop herself from shivering at the thought of how powerful he could become.

As Erza attacked Natsu again, he suddenly took a step forward and raised his hand to block her arm from moving, stopping her sword from making a contact with his head. Titania eyed Natsu carefully and dodged his fast punch by moving her body backward, however, by the time she realized that punch was just a decoy, it was too late.

Her eyes widened when Natsu was no longer in front of her, but behind her, moving so fast that she her eyes could barely follow. Erza saw him raised his legs to kick her but dodged it by ducking and quickly spun around and tried to slash the Emperor, who made a small smirk before grabbing her wrist with his hand, once again successfully stopping her from cutting him down with her sword. Natsu then pulled her toward him and thrust his palm into Erza's gut, making Erza cough out some saliva at the heavy blow and skidded to a stop a few feet from him.

The Scarlet Knight dropped to a knee and put a hand on her stomach, coughing violently as she tried to catch her breath. That blow was so strong, that she could feel the force go through her body after leaving a large crack on the part of the armor that protecting her abdomen.

"You okay there?" Natsu asked gently but didn't approach her, because he knew that the fight wasn't over yet. After so many years of having Erza fighting side by side with him, Natsu knew more than anyone that it would take a lot more than just a blow like that to take the mighty Titania down.

"I… I will." Erza nodded her head and pushed herself up, taking a deep breath and felt the pain disappear, somewhat "Shall we continue?" She asked, requiping her armor. Even in the past, her Entei no Yoroi was particularly useless against Natsu's fire magic anyway "Kanso!" in a flash of light, her armor was changed, taking the form of a beautiful silver gown, with a hem sprouting from it, being tied with a red belt with gold borders. The upper part of the dress included shoulderless sleeves and a flower petal on her left hand, parting slightly at the front and showing a lot of her large breasts, whiles the foot wearing were a pair of knee-high heel boots. Erza's scarlet hair also tied up in a ponytail, becoming wavy and was let freely flowed down her back. The armor also consisted of eight magical swords, floating in mid-air behind her back like wings.

"Wingblade Armor?" Natsu asked, raising an eyebrow at the sight of one of her stronger armors, Wingblade "I should be careful then." Elegant but dangerous, those were the right words to describe Erza Scarlet, the Scarlet Titania of Alvarez Empire "You should wear something like this more often Erza, you're just as beautiful as I remember." He couldn't help but comment.

"I will… if your majesty wishes me to." Erza made a small smile, lowering her head a little, feeling happy that her appearance was praised by Natsu. Maybe it's time for her to change her daily wardrobe since Heart Kreuz style had become obsolete many hundred years ago anyway " I shall wear this gown every day."

"Just my thought… there is no need for you to do it you don't like you know Erza." Natsu told her, but Erza kept her decision firm.

"But your wish is my command."

"That is not… sigh, it seems I can never change your mind, can I?" Natsu made a small smile while shaking his head. She had always been like that anyway, from the moment Erza became his guard, she began to take her duty very seriously, carrying out his missions and orders better than anyone, maybe even more than Gray, his chief of staff and counsel "Let's continue, shall we?"

"Yes, your majesty." Erza nodded her head and charged at Natsu, willing her blades into attacking him but the same result was given to her, no matter how fast and how many blades she used to fight him, as even with the swords' special power she still couldn't land any hit on him "How did you become so strong?" she couldn't help but ask as she caught one of the swords and fought him herself.

"During my journey, I tried to avoid attention as much as possible, but the world changed faster than I expected, and conflicts were unavoidable." Natsu said as he dodged to the left and kicked Erza, only for her to will her blades down to block his foot "I met many powerful beings but sometimes, they became wary of me and wanted to take me down before I could become a threat to them."

"So you fought them?" Erza asked.

"Not by choice… but I rarely got out of a fight unscratched." Natsu nodded his head "Even now, there're many powerful beings out there, and not many of them are as friendly as the ones we met lately."

"Let them come." Erza said strongly as she gritted her sword and held her chest high "I will cut down anyone that dare to stand against Alvarez."

"I'm sure that you will, Erza, I'm sure that you will." Natsu smiled before continuing to spar with Erza until Mavis arrived and asked for his company.

Line Break

It was an undeniable fact that Natsu was enjoying what he was seeing, standing with his back leaned against the wall of a gigantic bathroom and his arms crossed over his chest, his eyes planted firmly on the naked woman that was bathing under the shower inside the shower room before him, facing away from him. Natsu didn't expect to get invited into her bathroom with her when he first arrived at her room to ask her to carry out a job for him. The offer was very tempting, but the Spriggan Emperor chose to be a gentleman and decided to wait for her instead.

He chose to wait for OUTSIDE, but Irene used her world reconstruction magic to pull him into her bathroom because she believed that he shouldn't waste his time waiting for her to come out of the bathroom after spending her time enjoying a hot shower.

The moment he was pulled into her bathroom, Natsu couldn't keep his eyes off her naked body for a second, because she was so beautiful and her wet, naked body would definitely haunt his dream many nights.

"Are you sure you don't want to join me, your majesty?" the woman turned around and smiled at him, moving a few strands of her wet scarlet hair out of the way and crossed her arms underneath her large chest "I'm getting a bit lonely in here, and could really use some help from you." She gave him a seductive smile, one that could only be given by a mature woman like her. Her voluptuous, hourglass figure body was truly a sight to behold, and there were not many women in Alvarez Empire, or anywhere else in the world could rival her in that area. Her bust, which drew the attention, were so big that most of the water that came from the shower ended up hitting her them instead of the floor. She had a slim waist, a womanly, childbearing hip and a pair of legs that went on forever.

She had a super busty body and she wasn't shy to show it off, especially in front of the Emperor himself.

"On a different occasion, Irene, I would love to." Natsu shook his head with a smile "But you and I both know how a simple shower between a man and woman is going to end, so now is not the time for that… yet." The scarlet haired woman chuckled before turning back to wash her body, finishing her bath before his stare could really turn her on.

Irene Belserion, the Scarlet Despair of Alvarez Empire, she was formerly known as the strongest female member of the original Spriggan Twelve. After the death of Zeref and the war against Fairy Tail, just like Brandish and Dimaria, she accepted his offer to follow him, the new Emperor and became the new prime minister of Alvarez Empire. Irene had been very helpful to Natsu during his first year in power, filling him in every think he needed to know about his kingdom. Also, much like Erza, Natsu had also grown very close to Irene and formed a very strong bond with the beautiful lady, whose power was still hardly rivaled by anyone, even the new Spriggan Twelve.

"No hard feeling or trying to offense you, your majesty, but if I didn't know about your relationship with Mirajane, I would think that you're too gay or too dense to refuse such an offer." Both of them laughed as her statement "Don't worry, you're secret safe with me."

"I guess everyone knows about it?" He asked with a small smile, scratching the back of his head while looking away.

"Only between the girls," Irene shook her head and picked up a bottle of shower gel, "Erza told me, furiously. She isn't very happy with the way her best friend is sharing a secret relationship with our Emperor." She put her hand on her hip and made a very Erza-glare, pushing her incredibly large breasts out "A proper relationship between a servant and her master, she said." The two broke out in laughter once again "Seriously that girl need to do something with her attitude, or else she won't be able to find a decent boyfriend…"

"Don't worry Irene, it's how Erza is." Natsu smiled while shaking his head "Anyway, there is something I would like you to do for me."

"Sending your own prime minister to the field, I guess it must be very important then." The beautiful scarlet haired woman turned off the shower and grabbed a towel to clean her hair and body.

"I want you to head to Kyoto and pay a visit to Kyoto Youkai Faction's leader and her people." Natsu nodded his head "It'd be very rude if I didn't come to meet her personally, or sent one of my most trusted subordinates. I have already contacted Yasaka about your arrival, so there is nothing you should worry too much about."

"I see." Irene nodded and wrapped the towel around her chest before walking out of the shower room "What about the other Factions? Do you need me to come to them too?" Natsu shook his head at that.

"The members of the Spriggan Twelve will take care of the rest. You just need to concentrate on the meeting with the Youkai." After that, Natsu followed Irene out of her bathroom and into her room, where she once again stripped down to her birthsuit and put on her usual outfit.

"What about Sirzechs Lucifer's invitation?"

"I will handle that myself." Natsu nodded his head "Sooner or later, they will send the official invitation to me. I've already informed the others about it as well."

"Alright, I will prepare for the trip as soon as possible." Irene said before saying when Natsu headed out of the room "Let me know if there's anything more you need me to do."

"But you will need to finish your current task first. I will contact you later as soon as you return."

Line Break

"These are the requests the guilds of the north want you to give a look at." Minerva Orlando stated as she used her magic and dropped another stack of documents onto his table. Natsu looked at the documents emotionlessly, but deep down he was wondering why there were so many of them and how many hours it would take him to finish all of them "Your majesty, you know that you can ask me to do it for you." Minerva stated, leaning over slightly and put her hand on the documents "These… paperwork, they're not your jobs." Usually, Gray would be the one who sort them out orderly for him, but whenever he wasn't there, Minerva would the one who did it instead. Her magic provided her the necessary power to transport many documents to various places at the same time, as she had grown powerful enough to teleport herself or anything to anywhere on Arakitashia.

"As much as I want to agree with you, Minerva, yes they're not my jobs." He spoke up and grabbed the first document "They're my responsibilities. My brother viewed Alvarez as a pawn in his game, I don't and never will. I have the responsibility to bring Alvarez Empire back to the most powerful kingdom in the world, to protect it from any harm. I must become a better leader than my brother, and to do that, I must have my people's faith in me."

"You sounded like an old man when you said that, you know?" Natsu looked up and gave her an amused smile "Forget what I said, you're an old man, after all." She said teasingly, and they both laughed at that.

"Anyway Minerva, you can sit down and help me if you want to. I can really use another opinion here."

"Then, it'd be my honor, you majesty…" but Natsu suddenly raised his hand and turned his head to the side, as if he suddenly felt something or someone coming "What's wrong your majesty?"

"She's here sooner than I expected." Natsu stood up with a small smile. Turning to the Sabre-tooth Tigress, he said "Well then, Minerva, it seems I have to ask for your help this time. I will take my leave for now"

"Of course, it'd be my pleasure, your majesty." After that, Natsu left the place.

Meanwhile

The crimson teleportation magic circle that Sirzechs Lucifer left in the middle of Vistarion castle's guest room of Alvarez Empire turned silver and glowed brightly. In a flash, the strongest Queen of the Underworld, Grayfia Lucifuge appeared, no longer wore the French maid uniform, but a black business suit and a white shirt underneath, with two buttons left undone and exposed a fair amount of her generous cleavage. She was also wearing a long, silky green scarf around her neck.

"Lucifuge-san," The silver haired devil turned her head to the side when she heard the voice of a young woman with long and dark purple hair, wielding a long katana in her right hand. "My name is Kagura Mikazuchi, head of Vistarion's security squad. Welcome to Vistarion Castle." She greeted with a friendly smile, offering her free hand to the taller woman.

"It's my pleasure to be here once again, Kagura-san." Grayfia smiled and shook Kagura's hand "and please, call me Grayfia." She recognized the young woman from the information profiles the devil council had about Alvarez Empire. Kagura was a part of the squad that served directly under the shield of Spriggan, Scarlet Titania Erza Scarlet herself and the head of Vistarion's security department. While she wasn't the Spriggan twelve's member, Kagura's powers, especially her mastery over swordsmanship, weren't something one could underestimate.

"Very well, Grayfia-san." Kagura nodded her head "What bring you to Alvarez Empire today, Grayfia-san?"

"She is here to see me, Kagura." Before Grayfia could reply to Kagura's question, Natsu Dragneel pushed the door of the guest room open and walked in, with a smile on his face "Grayfia, it's my pleasure to see you again."

"And the honor is all mine, your majesty." Grayfia smiled and bowed her head at him, earning a nod from the immortal dragon slayer.

"Kagura, can you leave the two of us alone?" The swordswoman nodded her head and left the room, leaving Natsu alone with Grayfia "Please, have a seat, Grayfia. I cannot let my guest standing like this forever, can I?" The silver haired Queen nodded her head before taking her seat on the longue near the table in the middle of the room.

"I hope I didn't interrupt anything, your majesty." Grayfia spoke up when Natsu sat down on the sofa opposite from her "I should have informed you about my arrival beforehand before coming." She said worriedly while Natsu was pouring tea into two teacups.

"Do not worry, Grayfia. I was expecting your arrival, after all." Natsu shook his head and gave Grayfia one of the cups, which she took with both hands "You're not wearing your maid outfit, so you're not working as Sirzechs-san's maid today? Is this your day off?"

"Actually no, your majesty. I was still at work today, but decided to change when my master wanted me to come to Alvarez to meet you immediately." Grayfia shook her head "Because I don't think it's wise to come to meet you in a servant's outfit."

"Don't worry, while maid outfits around the nineteenth and early twentieth century was a bit different, those clothes reminded me of your mother, Silfia." Natsu shrugged "Your mother took her job very seriously, even during pregnancy."

"I see…" Grayfia smiled softly before asking "Your majesty…"

"Call me Natsu, Grayfia."

"Um… Natsu-sama, how did you and my mother meet?" Grayfia asked.

"I ran into her five hundred years ago while I was traveling to Eastern Europe." Natsu took a small sip from his teacup before continuing "After Alvarez disappeared from the surface of the world, many believed that I wasn't there and left to wander around the world. I covered my tracks very carefully and tried to stay in the shadow as much as possible. However, I made some mistakes, very small but they didn't go unnoticed by Lucifer, who had eyes all over the world. Silfia had always been Lucifer's favorite and most trusted servant, so he chose her to carry out this task for him. She was the first devil, possible the first being in the history managed to track me down."

"But you said my mother hid you away from Lucifer, didn't you?"

"Yes, not after she learned about his true intentions to my empire, and how much destructions and chaos they could cause. She found me but reported to her master otherwise. It was the first time ever she lied to the devil she was born to serve." Natsu nodded his head "And yeah, she talked him out of it and stopped him from continuing the hunt for me."

"I… didn't know," Grayfia said slowly.

"She was a brave and strong woman, Grayfia." Natsu made a small smile while looking at Grayfia "I'm so glad that you grow up to be just like her, strong and beautiful." Grayfia's eyes lowered a little, smiling and blushing a little at his compliment.

"Anyway, is there anything you'd like to tell me Grayfia?" He asked, tilting his head to the side to look at her "I don't suppose you came all the way here just to learn my connection with your mother." Grayfia widened her eyes before lowering her head, blushing even brighter in embarrassment.

"My deepest apology, Natsu-sama." Grayfia was so lost in his story that she almost forgot about her true intention.

"Don't worry." Natsu chuckled "So…" Grayfia reached her hand into her skirt pocket and pulled out an envelope with the crest of Devil Faction.

"Uh… yeah, I'm here to deliver my master's invitation for a visit to the underworld to you, Natsu-sama." Natsu accepted the envelope when Grayfia gave it to him "The Rating Game Championship is going to begin in three days, Sirzechs-sama is hoping that you can be there as an honored guest to our Faction."

"Alright!" Natsu nodded and opened the envelope to take the letter of invitation out, giving it a careful read before looking at Grayfia with a smile "Tell him that I will definitely be there in three days. It's been awhile since my last visit to the Underworld, so cannot say that I'm not looking forward to this."

"Of course, Natsu-sama." Grayfia stood up and bowed her head "Thank you, for accepting our invitation."

"It's my pleasure, Grayfia." He stood up as well and shook hand with her.

"It's time for me to take my leave. It's my honor to have this conversation with you, your majesty."

"I enjoyed it a lot, Grayfia." Natsu smiled "Hopefully it's not going to be our last."

"It won't, Natsu-sama." Grayfia shook her head "It won't."


End of Chapter 8


Yagami's note: Done! This is a new chapter for you. My deepest apology for making you wait that long for this chapter, but hopefully you will enjoy it nonetheless.

This chapter is yet another chapter for Natsu to spend his times with some of his female subordinates. They might be short, but it's only the beginning for more scenes in the future, as I have decided to go with option 1, having Natsu spends most of his time around his guards more than with the DxD World. However, I will add some DxD touches into it as well, like Natsu's upcoming trip to the Underworld to meet the devils themselves in their own territory.

This chapter also explained why Kagura was there even though she wasn't mentioned in the second chapter when the twelve guards were assembled before the Emperor. However, Kagura won't be the only ones, as I have decided to keep some more original characters of Fairy tail around. They will make their debuts soon enough in the future chapters, as Spriggan Twelve's Squads' members, as well as some other roles.

Hope this chapter satisfied you, especially the meeting between Grayfia and Natsu, which cleared some details about his past with her mother.

But I guarantee you that there are still many things Natsu hasn't told Grayfia… yet XD

Next chapter:

We learn about Natsu's mission for Gray.

Natsu summoned his very own Celestial Spirit, reuniting with his dearest friend after a thousand years. He will also get to spend some more times with his guards before arriving at the Underworld

READ and REVIEW (remember to review a lot for me! Like the previous chapter)

Ja ne!

P/S: Who should Natsu take with him to the trip to the Underworld?
