"Today we have a special game called Knockout,"

"I'M PLAYING THIS ROUND!" Natsu demanded.

"Hey fire-breath!" Gray yelled from the Fairy Tail team A base, "Are you really going to lose! Do it for Lucy!"

"What did he mean 'do it for Lucy' and why was he so… energized after that?" Lucy thought

"I feel the presence of the last key!" Gaito stated.

"It was right there!" Gaito exclaimed.

"Right there?" Lucy repeated, "You mean… THAT NATSU'S THE KEY!"

Chapter 5: Heartless

They accused her of something she didn't do. How could her family do something like that to her!? Then her role model came up to her and gave her, what seemed like, the worst slap of her life.

"You blonde! How could you!" She screamed as her hand slapped the poor girl in the face. The mob stood there ashamed at the blonde when she had the nerve to walk back into the guild hall. She then took her leg back as far as she could and kicked poor Lucy in the chest.

As the foot hit her chest, blood flew out of her mouth. She could barely stand up again and as she did her eyes met other furious eyes.

"You liar, you traitor!" They yelled at her as she slowly backed up the wall, she cried out his name but he didn't respond, just stood there silent then turned away.

"Stop!" she yelled, "Please, I'm innocent!" They did as she told. Lucy Heartfilla could not stop the tears as they streamed down her face. All of them looked down at her with disgust clearly written on their faces. Even he was looking at her with this disgusted yet confused face. A tear rolled down from his left eye as only a word could escape his lips.

"Why?"

Day 4 was beginning which meant it was time for the audience suggested battle rounds. One player was chosen from each team to compete in the battle rounds. Then the audience chose which players would fight against each other.

So far, Fairy Tail team A was in the lead with 58 points while Goddess' Fear was trailing 4 points behind with 54 points. The crowd went wild as Toma prepared to announce the players representing each team and which teams were to face off.

"Okay so from Lamia Scale we had Jura! From Blue Pegasus we have Ichiya! From Quartro Puppy we have Bacchus! From the reorganized Oracion Sies we have Nightmare! From Sabertooth we have Sting! From Fairy Tail team B we have Laxus! From Goddess' Fear we have Claire (aka Lucy)! From Fairy Team A we have THE NATSU DRAGONEEL!" Toma exclaimed as the crowd went wild.

"Today we will have Lamia Scale's Jura against Fairy Tail team B's Laxus! Then we have Nightmare against Sabertooth's Sting! Then we have Quartro Puppy's Bacchus against Blue Pegasus' Ichiya! And the fight we have been anticipating for, the legendary dragon slayer, Natsu Dragoneel! Against the newcomer Claire Lunairs! (If you ever read the Lunar chronicles I hope you saw that the stardust dragon was named Luna because I love that series even though its completely off topic!)

The crowd became even louder than before as they heard the last match. Lucy looked over at Fairy Tail team A's base only to see a grinning Natsu smiling back at her. She didn't know how to handle it. How could she face him! He's the strongest wizard Lucy had ever met! How would she beat him? The thoughts swirled through her head but a hand stopped her train of thought.

"Stop worrying about him so much!" Loke said as if he read her mind.

"I- I have no idea how I will beat him using just my Celestial Stardust dragon slayer magic" Lucy said. She had a huge reason for panicking. She only revealed to the public that she can use Stardust Dragon Slayer magic which isn't exactly true. She used Celestial Stardust Dragon Slayer magic. She can only cover up so much. Would only her Celestial Stardust Dragon Slayer magic be able to hold back the Natsu Dragoneel, the one she trained with and plus she watched almost every single extraordinary moment he created.

"Plus if he really is the key, then how would I beat him by using this magic?" Lucy added. The actual magic she could use allows her to use the Stardust magic she absorbed to convert it into a Water, Earth or Wind Celestial Dragon Slayer magic. Celestial Fire Dragon Slayer magic is able to be absorbed by Celestial Dragon slayers so if he is the key would she be able to use his attacks against him. That seemed like her only hope. But only celestial wizards could use Celestial Dragon Slayer Magic. At least Celestial Dragon Slayer magic increases speed and agility. All of that thinking drifted her off into a distant land because she didn't realize that her match was next.

Natsu on the other hand was all fired up.

"If Lucy is really here I will do my best for her," Natsu thought, "To make up for that horrible mistake that hurt her in the past." Natsu shivered. That's very rare for a fire wizard.

The fire and the disguised star met at the middle of the arena.

"I'm not going to go light on you because you are a girl," Natsu warned. Lucy didn't respond just backed up to their respected positions.

"And the match starts NOW!" Toma yelled.

Natsu was the first to attack. (Surprise surprise) He ran up to her as fast as he could.

"FIRE DRAGON IRON FIST!" Natsu yelled as his fist launched at Lucy's face. Lucy tried eating his fire but failed so the attack knocked her to the floor. As Lucy slid on the ground, a flash of her true self flashed for a second but turned back. Most didn't notice including Natsu and Lucy but this also affected her celestial spirit's disguises causing for them to flicker off for a second too.

"Lucy!" Loke yelled as Lucy looked up at the stands towards her celestial spirit. "Remember what happens to your magic when you are attacked!"

Lucy froze. The disguise. If she was hit too much, she would lose her disguise. She would also be forced to close her celestial spirits gates. Not good.

Lucy retaliated. She quickly got up. Natsu smirked.

"I didn't see one of those battle smirks in a while." Lucy thought as she pounded her fists together. She then dashed forwards at the Fire Dragon Slayer. He did the same.

"STARDUST DRAGON IRON FIST!" Lucy yelled as a golden light (somewhat like Loke's) surrounded Lucy. She then hit Natsu in the face. The crowd gasped. She learned a lot in the 9 ½ years or 11 months (earthen time) Lucy had been training with her Celestial Crystal keys. Natsu's fire had disappeared as he regained his stance on the playing field.

"Now THIS is going down in the records guys!" The announcer yelled as Natsu stood up again.

"FIRE DRAGON ROAR!" Natsu yelled as fire shot towards Lucy. Lucy could not risk yelling celestial again when she used her roar so she quickly used her Stardust magic to dodge the attack. Lucy was lucky that she had or else she would be suffering with some major burns by now.

"FIRE DRAGON WING ATTACK!" Natsu shouted as an extension of fire formed from his hands. He attacked and the fire hit the ground as Lucy dodged it again. Natsu grunted in frustration.

"FIRE DRAGON BRILLIANT FLAME!" Natsu yelled as the flames from his right and left hands collided which sent a huge fireball at Lucy. Lucy barely dodged it because part of the fire burned her leg. The disguise flickered for Lucy and the Celestial Spirits as she stood up again.

"Dammit," Lucy thought as the crowd erupted in cheers again.

"LIGHTNING FIRE DRAGON MODE!" Natsu summoned as lightning and fire engulfed Natsu causing for the crowd to go silent. Last time the crowd saw this mode was during Natsu's fight against both Sting and Rouge which were not easy opponents.

"LIGHTNING FIRE DRAGON ROAR!" Natsu screamed as the blast of lightning and fire engulfed Lucy. There was no dodging it now as she was engulfed with lightning and flames. Lucy watched as she felt the shock of her life as she felt her skin being bruised. She couldn't hold her magic anymore as the black of her hair turned golden and her one blue eyes turned brown. The girl fell to the floor as Natsu stood, speechless as not a single word left his mouth. He then collapsed to the ground.

"That… that was Lucy!" Natsu told himself as tears rolled down his face. The crowd silenced and you could hear a pin drop.

The guild reacted in several ways. Fairy Tail team A's eyes grew as they saw the blonde they once knew and loved on the ground. Gajeel's mouth was wide open while Cana dropped her bottle as the beer and glass scattered on the ground. This time, the 6th guild master fainted along with Levy but Jet and Droy were there to catch her. Most people were unaware of what happened to the Lucy Heartfilla that played a year ago. She caught the eyes of many when she used the power from the planets. Now here she is fighting against her former teammate. That was a big shock to the crowd. Yukino stood there astonished.

The second shocking part to it was that her teammates disappeared. The only reasonable explanation for them disappearing was that they were Lucy's celestial spirits. The crowd was still silent as the blonde slowly stood up. Her clothes also changed to a blue and white tank top and mini skirt as her whip re-appeared by her side. The only thing missing was her keys.

As she slowly stood up to shadow Natsu, she wobbled and almost collapsed again but still had the power to speak.

"I may have been your teammate," Lucy started, "But not anymore. You had the nerve to call me your 'friend' and you said that you would 'always be there for me.' HOW DARE YOU SAY THOSE LIES!"

Natsu sat there silent.

"So where was I this whole time you may be wondering? Well I've been training and looking for something. Something called the Crystal Key of the Celestial Fire Dragon." Lucy continued, "I looked everywhere including that gate you destroyed. That was where I learned that the little key I've been looking for was somewhere in this arena!"

Natsu then got up.

"And guess where it was!" Lucy questioned as he walked up to her. She also walked to him.

"YOU NATSU!" She screamed, "YOU WERE THAT KEY!" Natsu froze as Lucy put her small hand on his cheek. Natsu still didn't say a word as she went up on her tipi-toes and kissed the boy on his forehead.

"This match is over." Lucy said as she walked away. Natsu just turned. "I AM LUCY OF THE HEARTFILLA FAMILY! I WILL COMPETE IN TOMORROW'S ELIMINATION ROUND!" She declared as she turned back at Natsu with tears in her eyes, "EVEN IF I HAVE TO DO IT ALONE!" Those were her last words as she walked off towards the exit as the match was declared over as a draw.
