(Inspired by Rin and Len's Synchronicity. I was too lazy to find a video with English lyrics.)

Normal POV

The guild was currently alert and a blonde haired Celestial Mage was hiding behind her pink haired friend, hidden from sight. "We demand that you send Lucy Heartfilia to us! We know you're hiding her!" "She is currently on a mission. Why do you need her anyways?" Makarov asks. "That is classified information!" "You come in here demanding for one of my brats and say its classified information?" "Fine. She is needed for her voice!" "Her voice?" Cana asks. "Yes, her voice. There is a beast in an underground cavern. Every forty years a new singer is needed to keep the beast calm. We have an oracle that tells us who is the new singer. Lucy Heartfilia was chosen." "Well like we said, she isn't here." Natsu says. The council member looks at him. "Hm. You know, I have a special power, I can make people freeze in place around my target." "Interesting, but it isn't needed." Gray replies. Then the council member raises a hand, which glows blue, and freezes everyone in the room, except for Lucy, who is still hiding behind Natsu. She widens her eyes but stays quiet and still. "Come on out Heartfilia, I know you're here" She stays silent. "Then I'll just have to harm this girl" He grabs a frozen Asuka and puts a sword at her throat. Lucy steps out from behind Natsu, without hesitance. "Let her go. I'll come with you only if you leave my nakama be." "Deal" Lucy takes off one of her two necklaces. "Let me say bye if you'd be so kind' "You may. I shall only allow you to talk to one of them." Lucy stands in front of Natsu. Then Natsu can only move his head. "Don't do it Lucy!" "He'll kill Asuka-chan otherwise. Here." She puts her necklace over Natsu's neck. "You don't have to do this!" Natsu says, a pained look on his face. Lucy only strokes his cheek. "Come find me ok?" "Dammit Lucy!" Natsu yells as she walks towards the council member. Then as she and the council member disappear, everyone is unfrozen. "LUCY~!"

Lucy's POV

I start singing.

(I couldn't find a better song cuz I was lazy~. I really wanted to find a song about her being lost but I don't know any good songs~)

I just woke up in this dark cavern sometime ago. It was too dark down here so I don't know how much time has passed. A week maybe? I just woke up in a white dress with my hair down along with some jewelry. Apparently they changed me when I was knocked out.

I stop singing then I start coughing into my hand. I see blood. I start crying and I clench my fist. Natsu...hurry. I wipe the blood away and start singing again.

Natsu's POV

I pant and wipe the trail of blood away from my mouth. This bitch was tough. We, being me, Gray, Erza, and Wendy, found where Lucy is but this lady was blocking our way. Everyone was down except for me. Then the witch lady shoots a blue ball at me and I collapse to the ground, clutching the necklace Lucy gave me. I hear laughing then I hear something else. Singing...Lucy singing...I snap my eyes open and I attack the witch from behind. Her mask snaps off and I widen my eyes then fall into the cavern.

Lucy's POV

I continue singing as I look around and then I notice something in the dim light of the candles. I widen my eyes when I see pink, I stop singing. I run towards it. I get on my knees and shake him. "Natsu, Natsu!" I rasp out, my throat sore. "Please, wake up!" I continue to shake him. His eyes slowly open. "L-Lucy?" "Natsu!" I hug him. "Ouch!" Natsu winces. I pull back and help him sit up. "I found ya Lucy." "Yup!" Then we start glowing. I instantly look up at the beast I was singing to. "Thank You" I say. It nods and then sends us up. Back to the surface.
