**I don't own Fairy Tail or the characters. They all belong to Hiro Mashima.

So...This is the Natsu x Hisui fic. I decided to start with this based on the responses as well as my own frustration that I can't seem to find any completed Natsu x Hisui fics that aren't one-shots. My favorite pairings are Natsu x Erza and Natsu x Mira, but I like exploring possibilities with Natsu x any Fairy Tail girl (except Lucy).

The next one will probably be the Natsu x Kagura (or Natsu x Kagura x Erza, depending on how it plays out).

Anyway, here's chapter 1**

"You may come in now."

Makarov Dreyar sighed as he walked into the throne room. In the center of the throne room sat the king. On his right sat Princes Hisui Fiore, and on her right sat Arcadios.

"Your majesty," the wizard bowed deeply.

"Thank you for coming on such short notice, Fairy Tail master Makarov Dreyar," The king said. He motioned for the guards to leave, and soon they were alone in the throneroom.

"What did your majesty want to discuss with me?" Makarov asked, knowing all too well.

The king smiled. "Straightforward as always, eh Makarov? But that's what I love about Fairy Tail. Well, I guess I'll be straightforward with you, then."

"It's come to my attention that a certain member of your guild caused more damage in a fight than your guild could afford to pay. I've also heard that the council is threatening any banks who lend you the money to keep the guild alive."

Makarov sighed. "What's your point?"

The king grinned. "We are prepared to pay the debt out of the royal treasury, on one condition."

"And what condition is that?"

"The condition is that Natsu Dragneel be engaged to Princess Hisui E. Fiore. Their marriage will take place in 2 weeks' time."

"WHAT?!" Makarov's eyes popped out of his head.

"That is my condition," the king said.

Makarov looked at the princess, surprised by her lack of reaction. "But I can't just make one of my brats get married to someone he barely even knows!"

"I'm offering you a chance to keep your guild together, Makarov." The king said. "If you don't pay up, you know the council will disband you."

Makarov was furious, but he knew the king had a point. "Still…"

"I'll let him officially stay in the guild. Hell, you can move Fairy Tail to Crocus for all I care, but if you want to keep Fairy Tail Natsu Dragneel will marry Princess Hisui in two weeks."

Makarov grimaced. He was cornered. There was no way he would get a better offer. "Yes your majesty…"

"Good, then you need to sign these documents." The king handed him several official looking parchments.

"Natsu will need to sign this one," he added after Makarov had signed the ones he'd been handed. He gave him another document rolled up into a scroll. "I'll send one of my men along. Once it's signed, he'll bring it back right away."

"Yes, your majesty." Makarov sighed, still unable to believe what was happening. And just as unable to believe that the princess hadn't even reacted to the news…

~~~A few hours earlier~~~

"But dad, you can't just give me away to someone I barely know!" Hisui Fiore was red as a beet.

"So you're not happy with my choice of the next king?"

Hisui's face got darker, if that was possible. "I didn't say that… he's handsome enough, but I barely know Natsu!"

"You know enough of him," the king said. "I've seen how you smile every time his name is spoken. How you get angry when you hear the soldiers talking bad about his exploits. I saw how angry you were when the councilman here earlier said he shouldn't be allowed in a wizard guild."

Hisui smiled a little. "I know, dad. But still. It doesn't feel right marrying a guy I've only met a few times."

"Well," the king said with a smirk. "If you don't agree, I'll just marry you off to the next prince that Darton proposes."

"DAD! That's blackmail!"

The king sighed. "Like it or not, Hisui, you're eventually going to have to get married. Your mother is gone, so there won't be any more natural heirs. So you can either marry somebody you don't know at all because the defense minister thinks it'll make a great alliance, or you can marry Natsu, because I think he'll be a great protector and husband to you."

"But what'll Natsu think of that," the princess said blushing.

"It doesn't matter what he thinks," the king said. "He's in no position to refuse."

~~~Present time~~~

"Natsu!" Makarov yelled as he came into the guild. "My office! Now!"

"You're in for it now, Natsu." Erza said as the fire dragon slayer gulped audibly, following the old man into the guild master's office.

"Enjoy your punishment flame-brain!" Gray hooted as Natsu walked past his table.

"Take it like a man!" Elfman added.

"I thought you learned not to be so destructive…" Mira said as he walked by.

"Yeah, yeah…" he muttered. He finally made it to Makarov's office.

Makarov just sighed wearily. "Natsu, I swear you'll be the death of me…" He handed him a sheet of parchment and a quill. "Sign this."

Natsu signed the document without reading it and handed it back to the guild master. "What's the deal gramps?"

"Congratulations Natsu," the guild master replied. "You're officially engaged."

"What? To who?" Natsu glared. "Don't I get a say in the matter?"

"No you don't." Makarov said sternly. "And you're engaged to the princess."

"No way," Natsu tried to snatch the document, but Makarov pulled it back. "Gramps! I barely know the princess! I'm going to marry someone I'm in love with!"

"Sorry Natsu, but like I said, you don't have a choice. The guild is in over our heads because of you. The crown is willing to bail us out, but only if you marry Princess Hisui."

"Not gonna do it," Natsu growled.

"YOU WILL DO IT!" Makarov yelled, his magic energy becoming intense. "YOU CAUSED THIS MESS, NOW TAKE RESPONSIBILITY AND ACCEPT THE CONSEQUENCES."

"Yes master…" Natsu hung his head.

Makarov sighed. "I'm sorry, boy. I don't really like it either, but the princess is a nice girl, and pretty. How bad can it be?"

"Yeah," Natsu said brightening. "And if I marry the princess I'll be king someday, right?"

Makarov groaned, wondering how he hadn't realized this earlier.

As the two emerged from the back room, a pair of palace guards came to the front of the guild. As the members looked on, they took the document, then turned and inclined their heads respectfully to the dragon slayer. Then one of them said a few words to Makarov, who nodded.

"Attention Fairy Tail members. I would like to formally announce the official engagement of Natsu Dragneel and Hisui Fiore. The wedding will be held in 2 weeks at the palace, and all are invited to attend."

Jaws dropped everywhere in the guild, and for a few minutes Fairy Tail experienced something it definitely wasn't used to: silence.

Then everyone started at once. "What the fuck, flame brain? Why didn't you tell anyone you were seeing the princess?" Gray yelled as he charged Natsu, leaving his clothes behind.

One of the Rune knights stood in his way. "You will address your future king with respect," he commanded sternly.

"Future…" Gray blinked.

"Congratulations Natsu. Don't know how you kept it a secret," Erza said with a grin.

"Probably because I didn't know about it till just now," Natsu mumbled.

Erza's jaw dropped a little. Makarov motioned her to keep silent.

"Does your highness have any luggage?" One of the rune knights asked Natsu.

"Luggage?" He asked, confused.

"To bring with you to Crocus, your highness." The other explained.

"Why am I going to Crocus?"

The rune knights sighed. "Because you're engaged to the princess. You must prepare for your wedding, your highness."

"Hey," Gajeel, who'd just woken up, nudged Levy. "Why are they treating the Salamander like royalty?"

"Because he is royalty now," she whispered back. "He's engaged to the princess."

"WHAT?!" Gajeel yelled, jumping up from his chair, and falling over backward in the process.

"Master Makarov just announced it," she said. "How could you not hear him?"

"I was sleeping," mumbled the iron dragon slayer.

Of everyone there, Lucy looked the most shocked of all. Probably because she'd believed she was going to end up marrying the dragon slayer.

"Well," Natsu was saying. "I'd better get back to my house. Don't have much really except my hammock and a few pairs of clothes."

"Your highness won't need a hammock," one of the guards said. "And I think you'll find that your style will be changing once you live in the palace. Is there anything else?"

"Just Happy," Natsu said. "Happy! Come on! We're going to the palace!"

"Aye Sir!" The blue exceed jumped up, flying over to the group and landing in Natsu's arms.

And then they were off.
