[Normal pov]
Team Natsu in on a job. They're fighting against monsters, everyhing was looking good until they started to transform. From grey wolfs to bigger and stronger version of them.
"Gray! Behind you!" Lucy yelled as she was fighting in her taurus stardress. Just in time, Gray turned around and swing to the wolf and took it down.
"Thanks, Lucy!" He said with a smile and Lucy did the same.
After some time they defeated monsters and are on they way to get their reward, which is 500,000 jewls.
"Alright!!" Natsu said as he and Lucy fist bumped.
"You guys were awesome!" Happy yelled as he went and hugged Natsu.
"Thanks lil'pal! You were great as well!" Natsu said.
"Aye!" Happy said and Lucy smiled in their direction.
"What're you smiling about?" Gray asked as Lucy flinched.
"What do you mean? I'm not!" She yelled, embaressed.
"Oh come on, I know you long enough to know that you're admiring him." Gray said with a smirk as Lucy blushed like a tomato.
"What? That's not true!" She answered as she pushed him aside, away from Natsu, Erza and Happy.
"Why did you do that?" Gray asked again.
"I don't want them to hear your stupid questions." Lucy said as Gray smiled.
"You love him, don't you?" Gray asked as Lucy looked at him with a smile.
"Yeah, for a while now."
"Why don't you confess?" Gray asked with his hands in his pockets.
"I can't, I'm too afraid of the answer. Besides, I know that he loves Lisanna.." Lucy said as her bangs covered her eyes.
"Lucy... That's not-"
"It's okay Gray, I'll be fine." She said as she walked back to the others.

~Meanwhile, with Natsu~

"Hey, where are they going?" Happy asked as he looked at Lucy and Gray. That caught Natsu's attention. He saw Gray smirking and Lucy red as tomato, he's mood sudenlly changed from happy to angry.
"I don't know, Happy." Erza said as she looked at that direction as well.
"Maybe, Lucy's gonna confess to Gray." Happy said as a joke, but Natsu took it very seriously.
"What?!! There's no way! Luce would never like someone like Ice Princess!" Natsu said in rage, ready to go to where Lucy and Gray were.
"Do not disturb them!" Erza said as she caught Natsu's scarf.
"Let go, Erza! I don't trust him with Luce! I wanna go there!" He said and almost got out of Erza's grip.
"Hey! Are we ready to go?" All of them looked at the direction of the voice and it was no other than Lucy.
"Luce! Help me!" Natsu screamed for help as he was still struggling with Erza.
"Why are you holding him back, Erza?" Lucy asked as Erza let him go.
"He wanted to go separate you from-" Natsu quickly covered Erza's mouth.
"It was because I wanted to go catch Happy, he annoyed me." Natsu lied.
"Oh, okay. Let's go." Lucy said and they went on their way for reward.

~Later~

"I'm going home, bye guys!" Lucy said as she began walking out of the guilds door.
"We'll go with you!" Natsu and Happy said at the same time.
"You know that you don't have to, right?" Lucy said with annoyed face.
"We know, we just love your place." Happy said as they all began to walk to her home.
"Hey, can we make a sleepover?" Happy asked.
"Huh? What's that?" Natsu asked, confused.
"You don't know what a sleepover is?!" Both Happy and Lucy yelled at the same time.
"How do you expect me to know, I was raised by a dragon. How could I know what that is?" He defended.
"Good point. Well, basicly, sleepover is when friends gather in someones house and they play games, talk to each other and then fall asslep." Lucy explained.
"That sounds cool, let's do it!" Natsu said.
"Do you want it to be just us three or do you want me to invite the others too?" Lucy asked.
"Just us is fine.." Natsu said, with a little blush.
"Okay, three of us it is!" Lucy said.

"So what do we do first?" Natsu asked.
"Whatever you want." She said and Natsu smiled.
"Well, let's play strip poker!" He said and right after Lucy kicked him.
"No." She said as Natsu rubbed his cheek.
"No fair.." Natsu pouted.

~After playing cards, 01:20 am~

"Let's go sleep, it's late.." Lucy said and yawned.
"Sure!" Natsu said as he fell and automaticlly fell asleep on Lucy's bed, Happy was already asleep in Lucy's living room.
"Guess I'll have to sleep on the floor.." Lucy said as she started to get up from her bed but she felt an arm around her waist.
"No.. You'll sleep here with me." Natsu said as he pulled her in bed right next to him.
"N-Natsu, what are you doing?!" She yelled in surprise.
"Floor is cold, there's no way I would let you sleep there." He said as he hugged her close to himself.
"Okay fine, just because it's cold today.." Lucy said as she started to fall asleep in Natsu's arms.
"Sleep well, Luce.." Natsu said as he brushed away some hair from Lucy's face with his hand.

"Morning guys!" Happy yelled early in the morning.
"Ugh! Don't yell, it's too early!" Natsu grumbled.
"Let's go to the guild!"
"I'm going to bathroom first and you wake Lucy up." Natsu said while rubbing his eyes.
"Lushy! Wake up, let's go to the guild!" Happy yelled in Lucy's ear, but for some reason it was pointless.
"Lushy? Come on, wake up!" Happy tried to move her in order to wake her up, but again, pointless. Lucy just wouldn't budge.
"N-Natsu, s-something's wrong with L-Lushy..!" Happy shuttered.
"What do you mean?" Natsu yelled from the bathroom.
"I mean SHE WON'T WAKE UP!!" Happy screamed as tears streamed down his little face.
"What?!" Natsu screamed and came running to Lucy's bedroom.
"Luce? What's wrong?!" Natsu asked woriedly, shaking her.
"Luce! Please, tell me what's wrong!" Natsu yelled.
"We have to take her to the guild!" Happy said, crying.
"Right!" Natsu said as he picked up Lucy bridal stile and began sprinting in the guild's direction.
"Please be ok.." Natsu wispered as he looked at Lucy and few tears escaped his eyes.

"Wendy! Mira! Anyone, help!" Natsu screamed for help as he ran to the guild. He's feet were hurting like hell, but he knew that Lucy came first.
"I'm here, Natsu-san! What's wrong?" Wendy said as she came running.
"L-Lucy needs your help!" He said pounting.
"Get her to infirmary!" Wendy yelled as Natsu did so.

"What happeded?" Erza asked as she sat down, next to Natsu in the waiting room.
"I don't know... We were having a sleepover yesterday, we were just playing cards and fell asleep. Nothing bad happened, I don't understand why she wouldn't wake up!" Natsu yelled as he suddenly got up from the chair and punched the wall, making a huge hole in it. He's hand was bleeding and the bruises were already forming.
"Natsu! Why did you do that? Look at yourself!" Erza screamed as she came to wrap up he's hand in bandages, but when she came near him, she saw that he was crying. Her eyes widened, she knew that Natsu wouldn't cry over nothing, so that just made it harder for her heart to handle.
"I-I shouldn't be doing this, I'm hurting myself while Luce needs my support, I'm s-sorry.." Natsu said as he dropped to his knees and sobbed.
"Hey, she'll be okay. We all know Lucy and she's stronger than this. She will definately wake up." Erza said as she put her hand on Natsu's shoulder.
"Now, stand up and be strong for Lucy!" Erza screamed and left Natsu in shock. He widened his eyes and slowly stood up.
"Yeah, you're right.." He said as he gave Erza a friendly hug.
"Thanks, Erza!" Natsu said as she smiled.

~With Lucy~

"Hey, what is this? Helo?! Anyone there?" Lucy yelled to the darkness, waiting for the response.
"Hello, Heartfilia..." Someone's voice said, it was woman's voice, I've never heard it before.
"Who are you?" Lucy asked.
"I am the demon that was sealed in you when you were a baby.." The voice said and Lucy's eved widened.
"W-What?"
"I can give you anything you want; I can return your parents back to life, I can give you unbelievable amount of power, I can give you imortality, like I said: Anything You Want." She said.
"And what would you get in return?" Lucy asked and the voince got silent for a few moments.
"Your memories of your guild members." The voice said and it echoed through Lucy's head. All of a sudden she couldn't think, she wasn't Lucy anymore.
"Give me power..!" Lucy said with red eyes and an evil smirk.
"Your wish is my comand." The voice said and in moment there was bright light.

~Reality~

"Lucy-san?" Wendy asked, shocked as she saw blonde looking directly at her with red eyes (Her eyes are just like Zero Two's).
"Out of my way, kiddo." Lucy said and pushed Wendy away.
"What's with her eyes? Is that Lucy-san?" Wendy said as she tried to stop Lucy from leaving the infirmary, but Lucy was too strong and she was out.

"Luce? I was so worried, don't do that again!" Natsu said as he went and hugged her in relief.
"Get off of me, pinkie." Lucy said as Natsu backed away in shock.
"W-What? Y-Your eyes.." Natsu said as he saw her eyes.
"They're beautiful, aren't they?" She said as she smiled, showing her canines.
"You're not Luce! Who are you and what did you do to my Luce?!!" Natsu screamed.
"Who is Luce?" She said and smiled sinisterly. Natsu's eyes widened in horror.
"H-Huh?" He said in disbelief.
"What is it? Wanna test me? Do you want to see me ripping off my precious guild mark?!" She said as she made a ball of light in her left hand and slapped it on her guild mark. It vanished in moments. Natsu couldn't believe his eyes, he just watched once his best friend slipping into insanity.
"Lucy, snap out of it! Please!" Natsu yelled as he held her by her shoulders.
"Hands off." Lucy said as she pushed him and he flew to the wall and made a hole in it.
"Natsu-san!" Wendy said as she ran to him and started to heal him.
"I'll be on my way, I'll see you if I decide to destroy you all!" Lucy said the wings appeared behind her and she flew away.
"L-Lucy.." Natsu said as he fell unconcious from shock.
