At six o'clock Lucy and Erza arrived with sleeping bags and snacks. Juvia ordered a pizza and set up comfy pillows and warm blankets for them while Gray hooked up the TV and picked out a few movies.

"So I've got a few chick flicks and some horror movies, please pick a horror movie." Gray said.

"Alright Gray we won't torture you." Erza said.

"I don't know. I don't really like horror movies." Juvia said.

"If it gets too scary for you just hide under the blankets." Erza said.

The pizza arrived at seven. They ate it up then later put in a movie to watch. It was horror flick and both Lucy and Juvia were only taking a few peeps from their blankets. Erza wasn't scared at all, she just casually ate popcorn and said a few comments once or twice.

"Don't open the door." She told the main character on the TV screen. "Don't open the- Oh! She opened the door. Why are people in horror movies so stupid?"

"How are you not freaked out by this?" Gray asked Erza.

"I've seen stuff way scarier than this."

"Hey guys what time is the moon supposed to rise?" Lucy asked.

Gray checked his watch.

"Two minutes." He said.

All too soon the full moon started to rise up in the night sky. Gray quickly got up from the chair and pulled the curtains over the windows.

"Don't look at the moonlight!" Lucy said.

She, Juvia, and Erza immediately went under the blankets so they wouldn't see the moon.

"How long do we have to stay under here?" Erza asked.

"Until Gray covers all the windows." Lucy said.

"Alright ladies you can come out now." Gray said.

"Phew!" Lucy sighed. "Thank goodness."

"So back to the movie then?" Gray asked.

"No that movie is way too creepy. Can we please do something else?" Lucy asked.

"Karaoke DVD anyone?" Erza suggested pulling it from her packback.

"I don't think that's a good idea either." Lucy said. "Need I remind you of today's incident."

"Oh right. Sorry Juvia."

"No it's okay." Juvia said. "If you guys want to sing karaoke be my guest."

"You sure you don't mind?"

"Not at all. Hey it looks like we're running low on popcorn. You guys want me to fix some more?"

"That would be great."

Juvia went into the kitchen to fix another bag of made sure that the kitchen window was covered before entering and it was so she walked right in. Unfortunately the curtains were very old and worn, having a hole in the left side which allowed a little moonlight to seep through. Juvia saw the moon's reflection in a cup of water that had been left on the counter. Just like with Lucy, Juvia became drawn and transfixed by the moonlight. She moved her hand toward the cup and her fingers swished through the water.

Forgetting the popcorn completely, Juvia walked back into the living room where Erza was setting up the karaoke DVD and the microphone.

"So who wants to go first?" Erza asked.

"I would." Juvia said.

"Really?"

"Yes."

"Okay."

Erza handed Juvia the microphone .

"What song do you want to sing?"

Juvia didn't answer instead she began to sing vocally into the microphone. Her voice was unlike anything they had ever heard. It was beautiful but it had some sort of eeriness to it and it seemed to be coming from all around them.

"Wow she's really good." Erza said.

"Something's wrong." Lucy said.

"What do you mean?"

"Juvia's a good singer but there's something different about it. I can't put my finger on it but something's not right. Don't you think Gray? Gray?"

He didn't respond. He just stood there staring at Juvia, completely mesmerized by her voice.

"Gray? Yoo-hoo Gray." Lucy said trying to get his attention.

"Hello? Earth to Gray." Erza said snapping her fingers in front of his face. "Have you gone brain dead or something?"

"She has the most beautiful voice." Gray said dazed.

"He's totally out of it." Lucy said.

"Want me to slap him?" Erza suggested.

"No."

But Juvia's voice didn't just ensnare him. Before walking out of the kitchen she had cracked the window open so that whoever was near her house would hear her voice when she sang. Minerva happened to be driving by with Jellal in her car and Natsu was walking back from the beach. All three of them heard Juvia's singing and just like Gray, Natsu and Jellal became entranced by it.

"What is that?" Minerva asked when she heard it.

"It's amazing." Jellal said.

Jellal got out Minerva's car and followed the voice.

"Jellal what are you doing? Come back here!"

But he just ignored her and headed straight for Gray and Juvia's house with Natsu following close behind him.

"What is going on here?" Minerva asked in confusion.

Juvia finished her song and a pleased look appeared on her face when saw how Gray was staring at her, completely lovestruck.

"Did you like my song Gray?" She asked in a way that made her look both innocent and seductive.

"Uh-huh." He said nodding dumbly.

"Juvia are you feeling alright?" Lucy asked her.

"Of course. Why wouldn't I be?"

"Well it's just that you sang in front of us and you have major stage fright."

"I got over it."

"Just like that?"

"Yes." She turned back to Gray. "Would you mind coming with me to my bedroom? I need some help with something." She started to walk upstairs to her room.

"Okay." He said grinning and moving to follow her.

"Oh no you don't." Erza said grabbing him by his arm. "You wait here."

Lucy and Erza followed Juvia up to her room.

"Juvia." Lucy said. "By any chance did you look at the moon and touch water?"

"Would you be mad if I did?" She asked trying to look innocent.

"I'll take that as a yes." Erza said.

"How did this happen?" Lucy said. "Gray covered all the windows."

"Looks like he missed one or something."

"Alright let's not panic. What exactly happened to me when I was under the moon spell? What did I do?"

"You kept trying to get out and go swimming in the ocean."

"Don't worry I don't want to go swimming." Juiva gigled.

"You don't?" Erza said unsure.

"No. Not in the least. I just want to play with Gray. Could you send him up please?"

"I don't think so." Lucy said. "In fact I think it would be best for everyone if you stayed in your room all night."

"Alone?"

"No with us. We're going to stay in here with you all night and make sure that do anything that will get us into trouble."

"No offense but I'd rather have Gray stay with me all night and I think he would prefer it too."

"Not happening."

"Uh Lucy we have another problem." Erza said looking downstairs.

"What now?"

At the bottom of the stairway stood Natsu and Jellal with the same mesmerized look that Gray had.

"What are you two doing here?" Erza asked.

"We heard this awesome voice and we just had to know who was singing." Natsu said. "Who was it singing?"

"No one." Lucy lied. "It was just someone on the radio."

"No it was Juvia." Gray said. "She's so cool."

"Quiet you!" Erza told him.

"That was Juvia?" Jellal said. "Can we see her? Please?"

"Absolutely not!"

"Hi boys." Juvia said said standing at the top of the stairway with a flirty smile and wave. "Are you here to see me?"

Jellal and Natsu nodded.

"Would you sing for us?" Jellal asked.

"I suppose I could if you two did me a favor?"

"We'll do anything." Natsu said.

"Go outside and dance in your underwear."

"Alright." They said starting to get undressed.

"No!" Lucy and Erza screamed. They turned bright red and stopped them right away.

"Are you crazy?!" Lucy cried.

"Ignore what she just said and leave now!" Erza said.

"You get rid of those two and I'll get Juvia back into her room." Lucy said.

"Gotcha."

"Come on Juvia let's go back in your room so we can have a little talk." The blonde said pulling her blue haired friend into her bedroom.

"Alright you two get out of here! Go on! Shoo! Shoo!" Erza pushing Jellal and Natsu toward the door.

"Can't we stay a little while longer?" Natsu asked.

"No. Now beat it and keep your clothes on."

She shoved them out of the house then went back inside to somehow snap Gray out of his trance. All it took was a thump on the head to bring him back to his senses.

"Ow! What was that for?" He asked.

"Quick question Gray what do you think of Juvia?"

"What do I think of her?" He said. "I guess she's okay."

"Good you're back to normal."

"What are you talking about? And what just happened?"

"Juvia looked at the moon and touched water."

"That's not good. Is she scarfing down fish?"

"No but she's singing in a really weird way that made you, Jellal, and Natsu zone out and act really weird."

"How weird?"

"Juvia told Jellal and Natsu to dance outside in their underwear and they were going to do it."

"Oh..."

"She's also being really flirty."

"She sounds like a siren."

"A what?"

"A siren. Their mermaids from Greek myths who used their singing to lure sailors to their deaths. I hope this isn't as bad."

"Are you saying Juvia would try to kill men?!"

"Well judging by what you told me, it sounds more like she wants lure men to their humiliation not their deaths. Of course if Jellal was one of her victims I wouldn't stop her."

"That takes one weight off my shoulders."

"Hey Juvia didn't make me to do anything embarrassing did she?"

"No unless you count swooning and hanging your tongue out of your head as embarrassing."

Gray blushed.

"I was doing that?"

"The whole time she was singing."

"Oh God."

"Don't feel bad, Natsu and Jellal were doing the same thing."

"Really?"

"Yeah. The last time I saw Natsu drool like that it was over a burger. Gross. What is it with men unable to keep their jaws closed when they have crushes?"

"Well it's not like I actually have a crush on her or anything. It was the full moon."

"Right." Erza said rolling her eyes.

"Listen I'm going to get some ear plugs just in case she starts to sing again. You tell Lucy about the whole siren thing and try to keep Juvia from singing."
