It's been almost over a year since Natsu took Kuroka has his Queen, and they started their adventure around the Underworld, much to Kuroka's displeasure because Natsu made her walk everywhere they had to go, because for some strange reason he wouldn't let them go by any means of transportation.

"I'm tired Nyaa." Whined Kuroka has they were walking to the next town.

"Come on Kuroka, were almost there. " Answered Natsu.

"YOU'VE BEEN SAYING THAT SINCE YESTARDAY!" Yelled Kuroka. "Why don't we go by train anyway? We would be there by now."

"D-Doesn't matter" Said Natsu clearly hiding something.

{So you're not going to tell her about your motion sickness?} Asked Daenerys mentally to Natsu

'Everyone has their weaknesses. 'Thought Natsu answering Daenerys question.

"Wait…Why didn't you use the transportation circle?!" Shouted Kuroka, realizing after a year of walking around that they could of just teleported where ever they wanted to go.

Natsu shrugged while saying. "Funs in the journey I guess."

"Nyaa…I can't believe this, my master is an idiot…"

They continued to walk for about an hour until they finally reached the town. "Finally! Let's go to an Inn." Said Kuroka, wanting to rest after so many hours of walking, but when they reached the Inn Natsu stopped. "Come on Kuroka we have to go back to the Gremory Territory." "WHAT?!" Shouted Kuroka not believing what she was hearing "You make me walk around the Underworld for a year now, and you suddenly say we have to go back?! Why?!"

"Sirzechs just summoned us." Said Natsu making Kuroka immediately shut up after hearing that.

"What does he want, Nyaa?"

"I don't know, that's why I said we have to go back."

"Ok. But at least use the teleportation circle." Pleaded Kuroka, not wanting to walk anymore.

"Do you think I would be that mean"

"I don't know anymore…"
"Come on lets go." Said Natsu as Kuroka stepped inside the transportation circle that Natsu made.

Gremory Territory. Sirzechs office.

"Finally their here." Said Sirzechs has he saw a magical circle appear on the ground.

"So what do you want Sirzechs." Said Natsu as the light from the magical circle disappeared.

"I need you to help Rias." Said Sirzechs, surprising Natsu by what he said.

"Why? Did something happen to her?" Asked Natsu with worry noticeable in his voice.

"Don't worry Natsu. She's fine, I just need your help to protect her because there has been a lot of sittings of Fallen Angels in her territory in the human world, so I want you to go there and attend Kuon Academy to keep an eye on her."

"Oh. Ok, and what about Kuroka can she come to?" Asked Natsu.

"Yes she can." Said Sirzechs "But you'll have to go there a week earlier to get used to the human world since you've been in the Underworld for 14 years now."

"Ok anything else I should know?"

"Yes, try and not get found by Rias or her peerage. Oh and also apparently Kuroka's sister is part of that peerage."

"WHAT?! And you tell us now?" Shouted Natsu.

"Sirzechs-sama kept forgetting to tell you." Said Grafia

"You didn't need to tell him that Grayfia, well you better get going we already have a house prepared for you." Said Sirzechs he made a transportation circle under Natsu and Kuroka.

"Hey! What are you doing?!"Said Natsu has the light got stronger.

"Goodbye Natsu, remember, one week" Said Sirzechs has he was waving.

"YOU BAST…" Natsu never finished because he and Kuroka were teleported before he could.

"Phew. That was a close one, a few more seconds and he would destroy the building"

At the human world.

"-ARD! Wait where are we? Asked Natsu as he started to look around.

"Seems like our new place Nyaa." Answered Kuroka as she was looking around.

The house had two floors, in the first floor were the kitchen, living room, dining room, and a bathroom, in the second there were about 5 rooms and a bathroom.

"Well at least you're going to finally see your sister again." Said Natsu seeing the bright side in things.

"Yeah…" Said Kuroka trailing off at the end.

"What's the matter? You're not happy?"

"No I'm happy, It's just that I'm… Scared."

"Scared? Of what?"

"I'm afraid that she might hate me." Said Kuroka as she started to tear up.

"You don't have to worry about that. I'm sure that she doesn't hate you, you just have to explain yourself to her and you'll see that everything will be alright." Said Natsu as he hugged her to try to comfort her.

"Thanks for always being there for me Natsu, I don't know where I'd be right now without you." Said Kuroka to Natsu has he was giving her his toothy grin.

"Yeah, and whatever happens I'll always be there for you."

At that moment Kuroka couldn't handle it anymore so she did what she wanted to do for almost a year now. She kissed Natsu. He was surprised by what happened but didn't stop her, but decided that he was going to tell her.

When their lips separated Kuroka was the first one to speak.

"I've wanted to do that for a while now… I-I love you Natsu and I want to be with you." She said nervously because this was the first time she confessed to someone and she was somewhat afraid that Natsu would share her feelings.

"I love you to Kuroka…" Natsu said much to Kurokas happiness has she tightness her hug with Natsu. "But… There's something I have to tell you first." Natsu said causing Kuroka to look up to him confused.

"Nyaa?"

"I have to tell you how relations work with Dragon… And before you ask, Dragon Slayers have the same customs has Dragon." Said Natsu getting Kurokas attention. "You see a Dragon Slayer doesn't just go in and out of love, they only fall in love once. But I'm not a normal Dragon Slayer. I was raised by the Fire Dragon King, which technically makes me a Fire Dragon King Slayer, and any Dragon King from any element can have more than one mate… And to make things worse I also have the quality to be the Dragon King. So in other words, I'll have to have a certain number of mates." He finished, but then noticed that Kuroka had taken what he said quite well.

"You do know that High-Class Devils can have more than one wife right, and you're an Ultimate-Class so there's that."

"You've got to be kidding me…" Said Natsu hearing about this for the first time. "So all this time I've been worried about this, and it's normal for Devil's to have more than one partner." Said Natsu.

"Yeah, so I was already thinking of the possibility of you starting your own harem. You really didn't know? Asked Kuroka making Natsu shake his head in denial. "But it's interesting what you said, I didn't know Dragons were like that. So are you going to start a harem then?"

"Well yes and no." Said Natsu confusing Kuroka. "What do you mean?" She asked. "Well basically a harem is started by the lust of a man. But to me it will only have the people I find that truly prove that they can be my mates." Answered Natsu.

"What do you mean by proving?"

"If they really love me then a mark will appear proving that they share the same feelings."

"And how do you get that mark?" Asked Kuroka making Natsu slightly blush surprising her because in the year they've been together she never saw him like that, but she liked it.

"Well you see we have to…" Natsu said whispering at the end, causing Kuroka not to hear what he said.

"To what?"

"How do I put this…"

[Oh for Fuck sake, you have to have sex, procreate, fuck, chose one already there are a lot of words to describe what you have to do!] Daenerys said making Natsu false palm by the his straightforwardness.

"Ok" Said Kuroka surprising Natsu by how quick she decided.

"Wait, what?" Said Natsu thinking he heard wrong.

"I said let's go." She said grabbing Natsu and dragging him to a random room.

During that night the only thing you could hear on the streets of the neighborhood were the moans, screams and meows from Kuroka.

It was the next day and when Natsu woke up he tried to sit up only to feel some weight on top of him, when he removed the cover he saw a naked Kuroka snuggle on him, with a mark of a cat with a Dragon flying around it on the space between her right shoulder and her neck, then remembering what happened last night, but was brought back from his memories when he felt moving on top of him. When he looked down he saw that Kuroka was waking up.

"Good morning Nyaa." Said Kuroka giving Natsu a morning kiss.

"Morning. So you're comfortable over there?" Asked Natsu has Kuroka was snuggling in the crook of his neck.

"Nyaa." Was the only thing she said.

"I'll take that has a yes."

They stood there for a while, but then decided to go eat something.

"So have you met any other possible mates besides me?"

"Maybe."

"Nyaa? You don't want to tell?"

"Nop." Said Natsu wanting to end the conversation.

"Why? Are you embarrassed?" Asked Kuroka with a smirk on her face.

[Will you guys SHUT UP ALREADY?! I'm trying to sleep!] Yelled Daenerys.

"Wow. Someone is in a bad mood." Said Natsu

[I'm in a bad mood because someone was too noisy and didn't let me sleep last night!]

"Sorry…" Both of them said, remembering that Daenerys was there.

It was now night time and Natsu decided to go out for a walk, it was getting late so he decided to go home thru the park. When he came closer to a fountain he saw two people, a boy and a girl, but there was something weird about the girl, so Natsu decided to hide his presence and listened to their conversation.

"Hey Issei can do something for me?" Said the girl to boy now known has Issei.

"Sure whatever you want." Said Issei.

"Can you die for me?" Said the girl making Natsu prepared to jump in.

"W-What? Sorry Yuuma-Chan, mind repeating that? I don't think I heard you."

"I said… Can you die for me?" Said Yuuma has she stated to transform, she now looked taller and older and had two black wings coming out of her back, and let's say her clothes left little to the imagination.

'Shit!' Natsu thought 'She's a Fallen Angel! I have to help that kid!'

While Natsu thought that the Fallen Angel summoned a light spear, while Natsu started running towards them he noticed that the Fallen Angel was hesitating, but did not stop and throw the spear. Just as the light spear was about to pierce the boy Natsu caught it surprising the Fallen Angel, while the boy just fainted. Natsu could feel his skin of his hand burning because of the light, so with some force he broke the spear in to peace surprising the Fallen Angel even more.

"W-WHO ARE YOU?!" Asked the Fallen Angel.

"I'm Natsu Dragneel! And what the hell do you think you're … Shit!" Said Natsu confusing the Fallen Angel by how he ended his sentence.

"E-Excuse me"

"We have to go! NOW!" Said Natsu has he grabbed the Fallen Angel. "HEY! What are you…" She never finished because Natsu brought out his wings, which surprised her for him having Dragon wings, and grabbed her taking her out of the park.

When they left, a transportation circle appeared on the ground, and when it faded two women were there.

"There he is." Said the crimson haired one to the black haired one.

"That's weird… Why didn't the Fallen Angel kill him?" Asked the black haired one noticing that the boy is alive.

"I don't know, but I can feel its presence and there's also another one that I don't know to what it could belong to…" Answered the crimson haired girl.

"Well Rias, at least you found yourself a new pawn."

"I know Akeno. But I don't know why the other presence feels familiar…"

At the other side of the park Natsu and the Fallen Angel landed has she escaped from his grip.

"What was that for?" Asked the Fallen Angel, noticing the presence of two strong Devils where they just were.

"I just saved you know… You could at least thank me."

"I could have gotten out of there on my own."

"Sure you could…" Said Natsu while rolling his eyes.

"Why did you help me?"

"Why not?" Asked Natsu. "By the way, why did you try to kill him?"

"Because he's my target."

"What do you mean he's your target?" Asked Natsu

"Because he has something my higher ups want in his left hand." Answered the Fallen Angel.

"What?" Asked Natsu curious to know what the kid had that they would kill to have. 'Wait. If they want it why would they kill him?' Thought Natsu. 'They did not think that one thru…'

"A Sacred Gear." Said the Fallen Angel surprising Natsu.

"Well… What's going to happen to you now, since you didn't finish your mission?"

"The higher ups will probably have me killed…"

"Why would they do that?!" Asked a now enraged Natsu because of what he just heard.

"Because they don't need a failure like me… They told me before I left that if I failed to kill my target again they would kill me." She said in a depressed tone.

"And why would you stay with them if they treat you like that?!" Asked Natsu still enraged.

"I'M A FALLEN ANGEL!" She yelled surprising Natsu by the sudden outburst. "I have nowhere else to go… So I'll face the consequences for my failure."

"Let me make you an offer." Said Natsu getting her attention "Join my peerage and live under my protection, I'll get Sirzechs to clear you of your crimes."

"Do you think he could do that?"

"Yeah. He did the same to my Queen and she used to be a Stray Devil." Said Natsu

"You wouldn't want me… You saw it yourself, I was just about to kill an innocent person so you must know that I am not a person you want to be around with." She said depressed by the fact that she refused the first person that ever tried to help her.

"What? Of course I do." He said surprising her. "I don't care about what you did in your past, but I know one thing, you hesitated to kill him which tells me you have a nice heart. So will you join me…? Wait…What was your name?" Natsu asked realizing that he still didn't know her name.

"Raynare." The Fallen Angel now identified has Raynare answered.

"So what do you say? Will you join my peerage?"

"Sure Natsu. I'll join your…" She never got to finish because at that moment a light spear pierced her chest who fell on the ground covered in her own blood.

"RAYNARE!" Screamed Natsu as he looked up to see another Fallen Angel who was wearing a trench coat and a fedora.

"You disgraced the Fallen Angels race, not only did you fail your mission but also affiliate whit a Devil…" Said the Fallen Angel who was still in the sky

"You bastard!" Natsu said has he jumped towards him "Fire Dragon's Wing Attack"

"What the hell?!" Said the Fallen Angel who was sent flying.

"Crap! RAYNARE!" Natsu said has he rushed to Raynare. When he got to her he took out a Knight Piece and placed it on Raynare. Her wound started to close but she wouldn't wake up. Natsu started to worry that it might of not have worked, but then noticed that her chest was moving. "Thank GOD! Ouch! She's breading. Guess I'll have to carry her home…" Natsu said has he grabbed her bridal style and brought out his wings and flew home. 'I wonder how Kuroka's going to react to this.'

Natsu flew for some time until he reached his house. "I' back!" He said has he entered.

"Finally! Where were y-… Nyaa? Who's that" She asked pointing to the girl Natsu was caring.

"This is Raynare. Our new Knight!" He said.

"WHAT?!" Kuroka yelled "You go out for a walk and come back with a new Knight, just what happened?" Asked Kuroka wondering what kind of walk he was having.

Natsu told her what happened.

"You're telling me you made a Fallen Angel your Knight…" Kuroka said after hearing what happened.

"Aye sir!" Natsu said with a big smile on his face, happy by the fact that he had a new member of his peerage.

"Sirzechs' right, you are a weird Devil." Said Kuroka.

"When will you stop saying that?" Asked Natsu after hearing her say that for the hundred time now.

"When you stop being weird." Answered Kuroka.

[So in other words never.] Said Daenerys.

"SHUT UP!" Yelled Natsu causing both Daenerys and Kuroka start laughing.
