She longed to learn who she was and only he had the answer. Problem? He was in Sabertooth and she was in Fairy Tail, two rival guilds. On the road to get answers, she finds herself falling for his partner. [StingxOC] [RoYu] [NaLu] Other pairings inside.

The Shadow's Light

Sting X Nina (OC)

Dragon Battle.

Waiting for Natsu, Rosana's mind was spinning with all kinds of things: from her past getting closer to being answered, her weird attraction towards Sting, a growing fondness for Lyon and her own future within the guild all spun in her heart as she heard him arrive. "She feeling better?"

"Mhm. Let's go get some payback, Ros." He said, getting her to nod.

"Natsu. Rosie..." Happy said, getting their attention as Shina walked up next to him.

"Shina?"

"Happy, what's up with you two?"

"Nothin..." He said.

"Cool, let's go."

"We're not gonna say anything... You know what we mean?" Shina asked as the two looked to each other before nodding, holding the sign up as they walked out.

"And now... At long last, we've come to the battle everyone's been waiting for. One guild was considered the strongest in Fiore seven years ago and the other currently holds the title. This is going to be a great match. It's Fairy Tail's Natsu and Rosana versus Sabertooth's Sting and Rogue. You're about to witness a showdown of epic proportions. These aren't just any wizards. They're Dragon Slayers." Chapati said, silence in the arena.

"I've been looking forward to this all my life." Sting said, the three Dragon Slayers only able to hear him.

'This is it, my child. The time to prove yourself to him.' Skiadrium's voice echoed in her mind as she looked at her opponent.

"This is it, ladies and gentlemen. The Dragon Slayers are on the battlefield. Now the only question is who will be triumphant: the Fairies or the Tigers?"Chapati said.

"Let the match begin!" Mato said, the bell ringing.

"You ready?" Sting said, getting ready.

"Yeah."

The two rushed a few feet before they saw that Rosana and Natsu were rushing at them faster than expected, both landing a hard punch into their jaws and sending them flying back. Natsu went after Sting while Rosana focused on Rogue.

"White Dragon ROAR!" Sting said, shooting his breath attack off before aiming it at Rosana, who jumped to dodge it.

"Shadow Dragon Slash!" Rogue said.

Rosana engulfed her arm in shadows, easily blocking. "Shadow Dragon Wing Attack!" She sent him spinning into a waiting Natsu, who had his hand on the chin of Rogue, rushing at Sting and bringing him with.

"Fire Dragon Wing Attack!" He said.

"Whoa! I can't believe what's happening right in front of my eyes! The illustrious Sting and Rogue, the Twin Dragons of Fiore's mightiest guild have been overwhelmed by Fairy Tail's Shadow Mistress and Natsu!"

"You two are tough, that's for sure. Man, that makes it more fun." Sting said, wiping his chin.

"Nina." Rogue stated.

"Tell me somethin. Are you really like Rosie here? Did you really defeat your dragons with that measly power?"

"We didn't just defeat them, we killed them with our bare hands."

Rosie knew that was true for her, she had told Natsu that, but Sting? And it was expected that Rogue was, considering they are both Shadow Dragon Slayers. "I understand that, but didn't you think of him as a father?" She asked.

"That's none of your business, chick." Sting snapped. "But if you two losers wanna see our dragon slaying power, I'd be happy to show it to you! White Drive." He began to glow white.

"Shadow Drive." Rogue began to glow black.

Natsu looked to Rosana. "Can you do that?"

She scratched her temple, shaking her head in the negative. It must've been something he learned alone or something. The two got ready for the incoming attack.

"Ready, Sting?"

"Yup."

"The intense staring contest continues... You can cut the tension in the arena with a butter knife... Who will be the first to make a move?"

Sting immediately rushed at Natsu, catching the two off-guard with the speed displayed as Natsu barely had time to block the punch before he became a punching bag.

Rosana had her own match, glancing at Natsu. "Natsu!" She called before barely dodging an attack from Rogue before trying to go on the offense by attacking where he might've been, but was fooled and kicked in the jaw, landing on her feet. "Alright. Shadow tag, eh? I'm game." She also melted into the shadows to make it an even playing field.

"Would you look at that? Little Rosana has decided to match Rogue's Shadow Drive by going into the shadows as well!"

While in the shadows, each time they clashed, Rosie felt a familiarity about the attacks they threw at each other, getting forced out with an elbow, finding herself back-to-back with Natsu. "Yo." She said.

"Yo."

The two then looked up to see Rogue and Sting in the air, which made the two smirk as the others shot down, landing ontop of them. Rosie shook her head softly, dusting her clothes off. "It's rude to hold back in a fight." She scolded as Rogue made her go on the defensive while Sting focused on Natsu. A near miss had her hairtie torn, letting her hair fall out, along with the flower. Reflexes made her shadows grab it and teleport it to Shina, knowing her partner would watch it.

They began to get dominated by the two, who had great teamwork, while she and Natsu barely fought together, except for against Gajeel, but that was a long time ago. She kept trying to hit Rogue while Natsu soon became Sting's punching bag.

"You recall that a Shadow Dragon always gets its prey, correct?" Rogue asked.

Rosana spun and hit the air where he was moments before she felt the air shift, grabbing the wrist of the attacking Rogue. "Yeah, but you also never see it coming... Now, where were we?" She gripped a little tighter. "This is getting to be stale."

Evergreen rolled her eyes. "You can tell she's related to Laxus now."

Freed chuckled. "She was just toying with him before."

"You're not half bad, I'll give you that. But you'll hafta do better." Natsu taunted, cracking his knuckles.

"There's Natsu. Insane and brilliant at the same time." Gray chuckled.

"He is one of a kind." Erza agreed. "The same can be said for Rosie. She is our guild's only third generation, so she might be a little better than Natsu sometimes."

Rosie pouted playfully. "Weren't you cocky a moment ago? Where'd it go?" She dragged him down and elbowed him. "Never underestimate Fairy Tail, Ryos." She then spun and kicked him into the wall, along with Natsu punching Sting into the same wall.

"And just like that, the tide of battle has turned once again!"Chapati said.

"You two are pretty awesome alright, no shock there." Sting said, charging another attack. "Looks like we're gonna have to give you everything we've got. When we decide to go all out, there's no way fire and another shadow can stop us."

Rosana melted into the shadows and began a fight with Rogue in there once again, catching the fight and seeing that Natsu blocked the attack from Sting with one hand due to being in the shadows. She countered some hits while a few also grazed her before she punched him out of the shadows, joining him. She then managed to punch him into the back of Sting, where she and Natsu both kicked them similar to how they did them earlier.

They quickly got on the same page, each moving in sync with the other as they sent barrages of punches and kicks into their opponents before standing next to each other, each into the battle now.

"Those two are now on a whole other level." Yajima commented.

Rosie noticed the hole. "Feelin a breeze yet, Sala?"

"Nah." Natsu said as their eyes never left the other two. "You're hair's down. Looks cool. It's been a long time since I've seen it like that.

"Probably the last, too." She said.

"We're not finished yet." Rogue said, standing up.

"He's right. It's not like we expected this to be easy, ya know. Give us some credit." Sting added, also getting to his feet before he began changing. "I'm not gonna lose."

"I was wondering when they'd go there... They're not messing around..." Rosana commented, looking at her partner. "I guess I can let loose, eh?"

"Yeah, better be safe..." Natsu replied.

"Wait. They can do that too?" Levy asked. "I thought only Rosie could enter Dragon Force!"

Mavis blinked. "She can?"

Juvia nodded. "It's very taxing on her, though... But, she does it under extreme anger."

Cana grimaced. "It's rare to see her use it. Like yesterday was the first time in months that we've seen her in it."

Rosana got ready to enter her Dragon Force before she saw Sting walk ahead, making Rogue stay back. "The hell?"

"I can handle these two on my own." Sting said.

Glancing at Natsu, Rosie knew this was going to be a challenge. She could enter her own, but she didn't get the chance, since Sting managed to attack both of them as well as block their attacks easily. She wound up with a kick to the gut, sending her into the air before Natsu was thrown at her, right in the gut she was just kicked in.

"White Dragon's Holy Breath!"

The attack hit them and destroyed the floor of the arena, making them fall down and stun their guild.

"Rosie!" The Thunder Legion called.

"Natsu!" Happy and Romeo called.

As they fell, they both found footing on rocks, Natsu hitting Sting with his Sword Horn, sending him into Rosana. "Shadow Dragon's ROAR!" That made him hit the ground first while she and Natsu simply remained in the air, getting shocked when he stood up.

"The radience of a white dragon purifies all. HOLY RAY!"

She and Natsu found themselves getting blasted by multiple attacks before they were sent flying each time they tried to hit Sting, he countered the attacks before blasting them with another ray of light. It allowed her time to tap into her second origin while she decided to let him think they won, when she and Natsu were actually getting ready to shock them all.

"Change is inevitable. There's the proof. An older generation battered and beaten, while one of our generation joins them due to being weak." Rogue commented. "His era was grand, but now it's come to an end."

"Got that right." Sting said.

"Rosana and Natsu might not be getting up from that one, folks. It was an intense fight, but it looks like Fairy Tail might've succumbed to the strength of Sabertooth's Twin Dragons after all."

Shina shook as she let Evergreen hold her. "No way... Rosie..."

"No..." Levy said.

"Whaddya two doin lying around for?! Get up already! You two aren't allowed to quit." Gajeel stated.

"Never give up, Rose. I taught ya that when I trained ya!" Laxus shouted. "You can't roll over now."

"Get up, you two!" Romeo called.

"Are the two of them down for the count?" Chipati asked.

"Quit lying around and get up!" Gray ordered. "You two have a fight to finish!"

"We're right there with you two!" Erza added. "You're never alone! Because you're apart of Fairy Tail!"

"Sting." Rogue scolded.

"I know. Sorry bout the chick. I knew you wanted to test her. But I finally did it. I kept my word."

"Not so fast, pal." Natsu said as he and Rosana stood up, their clothes battered. He then rubbed his head. "My head hurts..."

Rosana cracked her back. "Imma need a long hot bath to get the kinks out... Man."

"It's as if Sting's attack had no effect on them!"

Natsu and Rosie both shared a grin as Natsu spoke. "Not bad. But now we've seen all your tricks... Especially you." He pointed to Rogue. "Growing up with Ros, you are the simpliest to figure out for me. The timing of your attacks..."

"The way they stand when they attack..." Rosie pointed out.

"Not to mention the rhythm of their breathing."

"What the hell? That's impossible! I used my Dragon Force!"

Rosie giggled softly. "Yeah, that shook me up a little. But, I haven't even entered mine, so it's hardly fair. They pivot their feet to ten o'clock for example."

"Exactly. So, we know exactly what to expect before they come. Ros, go ahead, you might need to go all out to keep up with me now."

"Sounds like I'm training with Laxus again." She said before she shifted into her own Dragon Force, adding her Shadow Lightning mode. "Alright, now I can let loose. Mind holdin back for a few, Natsu? I wanna take 'em on myself quick."

"No fair... Fine." He huffed.

"I didn't forget that insult. Come on, I can deal with you two boys by myself." Rosie taunted.

"INSANITY! Rosana Dreyer just declared her own one on two challenge against the Twin Dragons!"

Rolling her eyes, she smirked. "As Natsu'd say: 'I'm fired up now'."

Shina smiled. "You go, Rosie! Show those boys how to dance!"

Evergreen smiled as well. "Get a few punches in for the Thunder Legion."

Laxus even had a grin on his face. "Show 'em exactly why you're a Dreyer, Rose."

As if she heard them, she turned serious and raised an eyebrow.

"You think you can take us on alone, girl? That's a huge mistake!" Sting said, stunned while Rogue simply blinked.

"I only want to fight you one on one." He said simply.

"Meh. Beat me if you can, then. After that, we'll see about a single match, Ryos." She taunted as they entered their own Dragon Force. "Now this is a match~"

"There's nothing stronger than a dragon! You should know that, since you also have their power!" Sting said before he rushed at her, his fist glowing white.

"I don't believe you're even on Natsu's level quite yet. He's pretty strong.. So consider me a warm up to him. I think Natsu's roughly ten times stronger than me..." She admitted, blocking the punch.

"This is what you're capable of, girl! This is the true power of a Dragon Slayer! I should know! It's how I killed Weisslogia!" Sting said.

"Hmm. That so? Natsu, hop on in, I have a crazy idea!"

"Bout time." He joined her.

"If that's the power you used to kill a dragon... Then... We'll have to use the same kind of power we use..."

"To fight for our friends you laughed at!" Natsu finished as the flames and shadows of the two blended together and their two fists landed, sending Sting flying.

Rosana was quick to duck in time to see Rogue coming. "Shadow Dragon's ROAR!" The two attacks met before hers overpowered his as she let Natsu take care of Sting, while she focused on Rogue. "Bring it." She taunted as she and her partner soon became dominant once again, adapting to the strength of the two. While she naturally did so, Natsu was more of the physical learner and adapted after a few rounds.

Her body was one with the shadows and kept Rogue away from Natsu's fight, making him focus on her instead. They slowly became stronger than the other two as they launched a blast of their magic, it fusing half-way there.

"What an amazing battle." Jura said.

"What do you expect from him? My darling Rosana is simply divine when she fights." Lyon said, blushing lightly.

"Will you stop, Lyon?!" Sherria said.

She did back flips to avoid Rogue's breath attack before using her own, sending him into a wall before countering a few blows again. Soon, she and Natsu stood tall while Rogue and Sting were panting for breath.

"Now, STING!" Rogue said, a large ball of shadows forming in his hand.

"Yeah!" He replied, light mirroring Rogue's magic.

She glanced at Natsu and blinked. "Wanna...?" He barely nodded as they waited until the two unleashed the attack.

"BECAUSE NO ONE'S EVER GONNA TAKE STING DOWN!" The reddish Sabertooth Exceed shouted, tears flowing down his cheeks.

"Holy Shadow Dragon's Flash Fang!" They shouted in unison, firing off the blast.

It quickly approached her and Natsu, but she knew she and her friend would be able to over-power it as she summoned her shadows as Natsu did his flames, preparing for their own version of a Unison Raid as they felt the hope from their guild surround them, giving them the energy needed to pull through. "DRAGON SLAYER SECRET ART: Night Crimson: Exploding Shadow Flame Blade!"

Natsu ignited his arms and generates long torrents of flames from them, which move to hit the two in a spiraling formation. Each connecting strike generated a powerful, burning explosion while Rosana used her Shadow Dragon's Eruption to encircle the flames before they melted together, engulfing their opponents.

Rosie and Natsu stood as the dust cleared, her staring down Rogue while he stared down Sting as the two fell down.

"Unbelievable... The last ones standing are Fairy Tail's Natsu Dragneel and Rosana Dreyer!"

A few seconds pass and they high-five each other, Rosie grinning as he put an arm around her and the other in the air. "We did it, Natsu!"

"Hell yeah! Fairy Tail's not givin up!" He agreed as they celebrated their own way, him being Natsu and her just grinning like an idiot.

"Let's hear it for these two! They overcame Sabertooth's Twin Dragons! It's a huge win for Fairy Tail! They've moved into first place!"

Rosie's eyes brightened at that, looking at her friend. "Didya hear that?! We're FIRST PLACE!"

"Hell yeah!" He grinned as the two went to their opponent. "Let's fight again sometime!" He said.

"And I can't wait until I learn my past from you, Ryos~" She reminded gently.

"FAIRY TAIL IS GOING DOWN!" The four friendly guilds shouted.

"Watch out, my beloved Rosana, you're heart is mine." Lyon said seriously.

"My target is Laxus." Jura said.

"Titania." Kagura said.

"Let's find Gajeel." Ren said.

Once out, she hugged her best friend. "Shina, I'm sorry. Did I worry you?"

"Of course, but you were simply amazing." Shina said, smiling and reaching up to tuck the flower behind her ear.

"Let's go tell Lucy we're back on top." Natsu said.

"You two were freaking amazing." Gray stated.

"Thanks, man." Natsu said. "I don't know about Ros, but I had fun."

Rosie giggled and nodded. "Tons of fun."

Erza walked up and brought them both to her armored chest. "You two are something else."

"Ow... Thanks, Erza-chan..." Rosie said, rubbing the large bump softly before she met up with Laxus. "Told ya I could handle it, bro."

"Never doubted you for a second, lil Rose. Just rest up tomorrow. It'll be hectic the next day."

"We're gonna be number one in Fiore again." Gray said.

"I wanna fight you for being the fastest in the guild, brother, after the Games are done." Rosie declared to his chuckle.

"I'm looking forward to it." He said as they went to tell the good news to Lucy.

"It's good to see you two." Lucy said.

"You aren't gonna ask how our match went?" Natsu asked.

Rosie caught the blush grow on Lucy's face when she replied. "I don't need to. I told you I believed in you.. Since the very beginning."

"But this still ain't over..." Rosie reminded.

"We're just getting started." Natsu agreed, his grin making Lucy blush a tiny bit more.

"We still gotta win this thing, well, don't we?" Wendy asked.

"Of course, child." Charla said, smiling.

"Can't believe we started off in the bottom." Gray sighed.

"They even booed us." Rosie pouted before smiling. "Now they see our strength! We can taste victory."

"We're climbing back to the top. Fairy Tail wizards never back down and we're not starting now." Natsu agreed.

"LET'S WIN THE THIRTY MILLION JEWEL!" Makarov said.

"THAT'S NOT WHY WE'RE HERE!" The rest shouted in unison.

Rosie grinned as she skipped back to the the inn, getting even Freed to chuckle at her. "What, Freed?"

"The last time you had this kind of bounce in your step was right after you went on your first mission with Laxus." Freed said. "It's nice to see you this happy again, Lady Rosie."

Maaaan. I hope you liked it... I tried to figure out how Rosie's magic might work with Natsu's and came up with that move~ Still following what happened and there will be a huge shock in the next chapter~
