Chapter 18

Before class even started Natsu got fed up with all the noise that hurt his sensitive ears, so he quickly decided to not attend school and rather spend his time in the ORC building's kitchen. He quickly went to the supermarket to buy some ingredients that he needed to fulfil Koneko's request.

The day at school went without much embarrassment for the ORC members who stayed in class. Rias was very happy that her brother didn't cause any disturbances during the class. The peaceful day was disrupted as soon as class ended with rumours of someone cosplaying in the gymnasium.

Rias and Akeno had met up with Sona and Tsubaki just before they caught wind of the rumours.

"I have a bad feeling about this," Sona said with a look in her eyes saying that she didn't want whatever she was thinking to be true.

The four ran into Issei on their way to the gymnasium who wanted to see who this person was that was cosplaying.

A large crowd was gathered in the gymnasium so it took some squeezing between people before the group was able to see exactly what was going on.

On the stage in the gymnasium was a beautiful girl who appeared to be in her late teens with black hair that was tied into twin tails and blue eyes. She was wearing a pink top with a tiny white jacket and a big pink bow over her chest, a pink skirt and pink and black socks that reached up to above her knees and black shoes with small pink bows where the lases would have been. She completed her look with a pink hat and pink sceptre that had a big golden star in a pink circle on to top.

This girl was cosplaying as one of the popular show Magical Girl Milky Spiral Seven. Sona's face immediately turned bright red when she saw who it was that was cosplaying.

"Sona isn't that your sister?" Rias asked before turning and seeing her now red friend.

It looked like she wanted to melt into the floor and disappear. Tsubaki thinking quickly started herding the masses out of the gymnasium using her Student Council position to enforce her actions saying that the show was over.

"So-tan come and say hello to your big sister," the girl came running towards them and embraced Sona in a big hug.

"Do you have to embarrass me like that?" Sona asked trying to escape from the hug.

"I'm so sorry So-tan I didn't realise you hated your older sister," the girl started crying fake tears embarrassing Sona even more.

Before they could say anything else Koneko came bursting into the Gymnasium at incredible speed.

"Koneko is everything all right?" Rias asked with a little panic in her voice once she saw the wild look in Koneko's eyes.

"You must all go to the ORC building immediately. Do you know where Wendy, Grayfia, Asia, Kiba and Sirzechs are? I need to know now," Koneko asked with urgency in her voice.

"I think they should be near their last classes but what is going on?" Rias asked but was unable to get an answer as Koneko sped off to who knows where leaving six very confused people in the gymnasium.

"Let's go see what is going on at the club building that has gotten Koneko so worked up," Rias said as the group quickly made their way over.

When they arrived they didn't see anything out of the ordinary their concern for the white-haired girl grew. Koneko then burst through the doors with the rest of the ORC members and Grayfia and Sirzechs in tow with the same confused expressions they had.

"Ok Koneko now that we are here can you please tell us what is going on?" Rias asked with concern.

"Natsu told me that he will only give me the ice cream cake he made if everyone was here and that I had to share some of it," Koneko replied.

"Natsu I have brought everyone," Koneko caked out. The entire group was stunned and they did not know how to respond.

Natsu came out of the kitchen with a coffee ice cream cake that looked delicious and the group decided to wait until after they had eaten the cake to talk to Koneko about not causing them unnecessary trouble by giving them the impression that something was horribly wrong.

"And who are you hot stuff?" the cosplay girl asked Natsu.

"Hello there I'm Natsu Dragneel nice to meet you," Natsu greeted with a smile.

"I'm Serafall Leviathan nice to meet you Na-tan" Serafall returned the greeting with her own smile and already giving Natsu a nickname.

"Are you friends with Rias or Sona?" Natsu asked.

"I'm So-tan's older sister," Serafall replied.

"So you are a devil as well and since your last name isn't Sitri like Sona's but Leviathan I can only guess that you are one of the Satans?" Natsu asked looking at the girl in pink.

"You are a smart one Na-tan. And how do you fit into the picture, are you part of Rias' peerage?" Serafall asked.

"Oh no, I'm not part of any peerage, I'm not even a devil" Natsu said with a smile in anticipation because he enjoyed the reactions people would get once they found out he was the Dragon King and a demon.

"And why is that? You do know there are a lot of advantages to being a devil and in a peerage?" Serafall inquired.

"I just don't see any way that becoming a devil will actually help me to be honest" Natsu said with a mischievous smile.

Everyone besides Serafall had an idea as to what Natsu was doing and they were more than happy to just sit back and watch as Natsu toyed with Serafall since they have all been a victim to her childish antics at one time or another.

"If you become a devil you get an increase in magic power and if you go up the ladder you can become a high-class devil with your own peerage. You can also gain a lot of fame and fortune like that if you are strong enough," Serafall explained some of the benefits of being a devil.

"I don't think becoming a devil will increase my magic power as for the peerage and fame, let's just say I already have a large following," Natsu said with a devious smile enjoying how Serafall was trying to convince him of how great devils are.

"How do you know becoming a devil will not increase your power? If I for instance accepted you into my peerage it is guaranteed that you will get an increase in power since I am very powerful being one of the four Satans," Serafall now got a bit irritated that this guy doesn't want to become a devil.

"Trust me I know that becoming a devil will not increase my power, even if it was you who offered. Now that I think about it becoming a devil might even decrease my power," Natsu was at this time just saying anything to see how mad he could get Serafall.

"Are you mocking my power?" Serafall was starting to get angry.

"Not at all, all I'm saying is that your power is below mine" Natsu said with the cockiest grin he could manage.

"That is it. I challenge you to a duel and the loser will become the winner's servant," Serafall exploded.

"Let's make the whole servant thing only for a limited time… how about one day?" Natsu offered not wanting to have her make a decision she will come to regret.

"What getting scared of losing? I promise not to be a bad master," Serafall attempted to tease Natsu.

"Not scared at all, I just don't want to take one of the Satans as my personal servant," Natsu said keeping his cocky grin on his face.

"I was going to go easy on you but now I will not hold back," Serafall screamed in rage.

"Don't you think you have taken this too far Natsu?" Sona asked feeling sorry for her sister.

"What are you saying So-tan? Do you honestly think this guy can beat me?" Serafall asked with a hurt expression.

"I'm sorry Serafall but I have seen first-hand what he is capable of," Sona replied.

"I will just have to prove you wrong then," Serafall said with a huff.

"Sirzechs can you please organize a dimension for me so I can beat this guy into the ground?" Serafall asked her fellow Satan.

"No need for that I have a perfect place for out little duel. I promise you will love it," Natsu interrupted with a smile.

"If you say so Natsu," Sirzechs replied with a shrug happy to not have to create a dimension that would be able to contain the strength of these two powerhouses.

"Are you going to take us back to your realm Natsu?" Wendy asked hoping she could see Eossinth again.

"Yes I am Wendy," Natsu smiled down at the blue haired girl.

"What are you talking about 'your realm'?" Serafall asked.

"I'm interested in this as well," Sirzechs said.

"You'll see soon enough," Natsu replied with a smile.

"Before we go anywhere can we please eat the ice cream cake," Koneko begged.

"I almost forgot about that," Serafall's attitude took a complete one-eighty at the mention of the ice cream cake.

"I assume it is all right with you then that we postpone our duel for a little while?" Natsu asked Serafall with a smirk after hearing her remark.

"Well of course. Ice cream cake is one of my favourite deserts so you better not have messed this up," Serafall threatened.

Natsu gently cut the cake up into smaller pieces making sure to give Koneko the largest slice since she was the one who requested it.

"Why does she get the biggest piece it's not fair," Serafall whined in a childish manner.

"She is the one that asked me to make one so she deserves the most," Natsu replied in a matter-of-fact tone.

Everyone took a seat with Koneko quickly sitting on Natsu's lap. As Koneko took a bite her eyes lit up.

"This is the best ice cream cake I have ever tasted," she cheered prompting the rest to take a bite.

"You're right Koneko this is amazing," Wendy commented after taking a bite.

"As expected of my Natsu," Akeno praised her boyfriend and gave him a quick peck on the cheek.

"You must come to the mansion and make this for our mother sometime," Sirzechs said as he tasted the delicious desert.

"I don't mind as long as you provide the ingredients," Natsu replied.

Grayfia tried to hide her excited expression from tasting Natsu's food once again because she didn't want to tarnish her reputation with Serafall who was infamous for being unable to keep a secret.

Issei took a large bite resulting in a bad case of brain freeze which Asia quickly eased with her magic.

Kiba and Tsubaki silently enjoyed the treat while Sona hummed in delight at the taste.

Serafall took a hesitant bite before quickly taking another bite followed by another until her slice was gone.

"Is there any left? That was the best ice cream cake I have ever tasted," Serafall exclaimed.

"I'm sorry to say but there isn't any left," Natsu replied.

"After I win I will have you making me ice cream cakes for an entire day," Serafall declared.

"First it is unhealthy to only eat deserts for an entire day, two I can do a lot more in the kitchen, and three who said you will win?" Natsu replied with a sly grin.

"Are you saying you can make other things in the kitchen?" Serafall demanded.

"Natsu is the best cook ever," Wendy decided to answer the question for Natsu.

"Yeah, he makes the best sweet treats ever," Koneko added her opinion to the conversation.

"I will be happy to make you all a nice dinner tonight after I win the duel," Natsu said knowing the last part would get a rise from Serafall.

"You are so going down in the most painful way possible," Serafall threatened which Natsu just laughed at.

After everyone was done eating Natsu collected everyone's plates and went to clean them. Grayfia went to help him and made sure he could not turn her help down. Natsu happily accepted her help after she made it clear that she had no intention of sitting idly by while he does all the work.

Grayfia secretly also wanted to spend some alone time with Natsu. They talked while they were cleaning the dishes with Grayfia expressing worry t=about the fight and Natsu assuring her he had everything under control.

"SO everyone ready to watch me wipe the floor with little miss Leviathan over here?" Natsu asked once he returned.

"Shut your mouth, I will be the one wiping the floor with you," Serafall angrily shot back.

"But you are so easy to get angry," Natsu responded with a grin plastered on his face.

"Let's just go already I'm getting tired of hearing you teasing her Natsu," Rias said.

"As much as I enjoy seeing her get frustrated and teased for once I have to agree with Rias on this one," Sona said.

"All right then let's get going," Natsu said as he snapped his fingers making a portal appear next to him.

"After you," Natsu bowed and extended his arm.

The ORC members walked through the portal without a second's hesitation, Grayfia followed after Natsu gave her a kind smile and while Sirzechs looked a little sceptical but decided to walk through the portal. Serafall looked at Natsu with a sceptical look.

"It will be perfectly fine I don't intend on backing out of this duel and don't worry the place we will be going to is not some malicious place you'll be perfectly safe," Natsu assured her.

"Fine but know that you cannot get any outside help even if I am busy pounding your head into the ground," Serafall stated before walking through the portal shortly followed by Natsu.

As Natsu came out of the portal he was amused by the expressions of wonder on Serafall, Grayfia and Sirzechs' faces.

"Where exactly are we?" Sirzechs asked.

"This place is so beautiful," Grayfia said.

"Welcome to my home. The Dragon Realm," Natsu announced.
