A/N Here's the rewrite of the request from ObeliskX. Hopefully this time around it is better! I don't own Fairy Tail.
Prompt: NaLu in world where Loke is Lucy's companion and Natsu is celestial spirit.
"I don't know why we're searching for keys when all you'll ever need in life is right here!" Loke said with a sigh while following Lucy around a magic shop. Lucy had just gotten her rent paid and had an abundance of left over money so she decided to go looking for more celestial gate keys. Unfortunately her mission partner, and close friend, Loke decided to join her on the hunt for more spirits.
"I didn't ask you to come." Lucy replied shortly as she admired a dusty book. It lost her attention in seconds and she kept striding down the narrow shelves filled with magical trinkets. Loke rushed to catch up with her as she made a sharp turn around the corner of a shelf.
"Oh but what kind of hero would I be if I left a princess all alone?" Loke said arrogantly.
"You were a hero?" Lucy asked nonchalantly before her eyes lit up. "Yes I found one!" Lucy rushed towards a small table near the back of the store. On the table was a single gate key with a small symbol of fire drawn on the top. It pulsed slowly, almost in time to Lucy's heartbeat and she almost tripped over herself on the way to grab it. The metal was warm in her hand but not enough to burn and in the light the key looked like it had scales on it.
"Isn't it beautiful?" Lucy asked Loke excitedly. He stopped his playful flirting to awe over the key as well. The two stood there staring at the key until the sound of chimes broke them out of their reverie. The shop door had ust opened and a new customer was coming in.
"We should buy it quickly." Loke suggested and Lucy rushed to the front counter.
"I would like to buy this gate key please." Lucy smiled politely while setting the key down.
"That will be 40,000 jewels please." The shopkeeper said without looking up from his newspaper. Lucy frowned deeply before reaching into her wallet and grabbing the money. All that was left in the hot pink clutch was 10 jewels. Maybe if Lucy begged Mira, the barmaid would let her eat at Fairy Tail for free. There wouldn't be groceries in her apartment for weeks. At least rent was already paid, Lucy reasoned with herself as the shopkeeper handed the key to Lucy and shooed her out the store.
"Are you going to summon the spirit? Can I be there?" Loke asked casually as they began walking the cobblestone path back towards Fairy Tail.
"I should probably summon them now. Okay why don't we do it at Fairy Tail? Levy-chan was asking if she could see a summoning…" Lucy said before picking up the pace. In no time Lucy and Loke were at Fairy Tail. As soon as they entered the two doors, loud laughter and shouting overwhelmed Lucy's senses.
"Hi Lu-chan!" Levy greeted as she caught sight of her friend.
"Hi Levy-chan!" Lucy greeted back and hugged Levy. Next to Levy sat Gajeel and Lucy waved politely at him. "I just got a new key and thought I would summon them here. Do you want to see?"
"I really get to see a summoning?!" Levy's eyes shined with excitement as Lucy grabbed the key and closed her eyes.
"I am the gate between two worlds. Allow safe passage for this spirit. I summon thee, Gate of the Dragon: Igneel!" Lucy said before a small fire appeared in the room. It blazed ferociously until a boy burst out of it. He looked to be around Lucy's age and had pink hair.
"Back in Earthland oh yeah!" he grinned wildly and Lucy smoothed her hair down before holding out a hand.
"Hello. Welcome Igneel. I'm Lucy and I summoned you. What days are you free for summoning?" Lucy asked kindly.
"There seems to have been a mistake. I'm Igneel's apprentice Natsu. Someone must have given you a false key. Despite that I'm available for summoning whenever." The spirit, that apparently wasn't Igneel, said.
"That shopkeeper." Lucy seethed. "I paid the correct amount an ddidnt cause any trouble in their tore and was perfectly respectable! How dare they? I'm marching over there nad demanding a refund and apology. Mislabelign fo a key should knock 10,000 jewels off the price at least." Sometime during Lucy's rant, Natsu had gone towards the bar and began ordering food from Mira. By the time Lucy calmed down, there were fifteen plates stacked in fornt of him.
"That will be 35,000 jewels sir." Mira smiled at Natsu before clearing the plates.
"Hey Lucy can you pay for this for me? I would do it but spirits don't really have to buy things so I don't have money and since you're my master…" Natsu trailed off sheepishly and Lucy had to stop her left eye from twitching. After many hours of persistent begging, Mira agreed to forget the cost as long as Lucy went on a series of blind dates with people from the guild.
From that day forward there was a celestial mage that always lived in poverty. Accompanying her was a spirit that did nothing but destroy things and get the brunt of his master's anger.
Happy ever after?
