Confession at Death's Door

Natsu, Luna, Happy and Elise were on Tenrou Island as part of their training journey when suddenly, a loud crash noise followed by a tremor caught their attention. They went to go investigate and discovered a strange tower structure on the shore of the island that had not been there before. They were met by three people who made up a dark guild called Hell Spawn which was an affiliate of the dark guild Tartaros. Their names were Frostus Mergard, Scraporio Ergonan (Scrap) and Myne Coranos. Natsu, Luna, Happy and Elise learn the horrible truth that the magic nullifying operation started by Tartaros wasn't over. In fact, it was worse. Hell Spawn intended to nullify magic across the entire world using the MNTs (magic nullifying towers) they constructed using the pieces of the face pillars as cores in the towers. Right as Frostus was about to leave the island, Natsu tried to stop him. Frostus then shot an ice ray at Natsu, but Luna intercepted the attack and got hit instead. She fell to the ground unconscious, frozen as Natsu just stood there in shock.

"What a pity. I meant to hit the fiery one. Oh well, at least I got one of them." Frostus said as he looked back with a mocking expression of fake disappointment then headed off on his way with his guild members.

"You bastard! You'll pay for this! No one hurts my comrades and gets away with it!" Natsu yelled in the direction Frostus and his guild mates had gone, but they had disappeared.

"Luna no... why did this happen?" Natsu fell to his knees beside Luna. Happy and Elise ran up to them as Natsu scooped up Luna in his arms and caressed her cheek. She was cold, too cold. Because Luna was an ice dragon slayer, she was always cold to the touch. But this was cold even for her. Luna's normal temperature was refreshingly cold. Her current temperature was freezing bitter cold. Natsu put his ear to her mouth, then her chest to see if she was still alive. She was breathing and her heart was beating, but her rates were slow like she was barely clinging to life.

"She did it to protect you. If that ray were to hit you, Natsu, you would have died instantly from shock. Because Luna is an ice dragon slayer, the ice ray only put her in a coma. Even so, this extreme cold could still kill her. You will need to warm her up in order to revive her Natsu." Elise explained as she stroked Luna's cold cheek with her paw before looking up at Natsu with a serious expression on her face.

"Okay I can do that, leave it to me! Stand back everyone. Fire Dragon's Roar!" Natsu said as he breathed in, about douse Luna in flames to warm her up. But Elise grabbed Natsu's arm and tugged hard, causing him to pause and look at her.

"No! You can't warm her up too fast. That could make her go into shock. You have to warm her up gradually. Take off both yours and Luna's clothes, lay on top and increase your body temperature slowly and steadily." Elise instructed Natsu as he just stared at her, his head tilting to the side.

"Huh? I have to do what now?" Natsu asked as Elise pinched the bridge of her nose and shook her head.

"You have to remove Luna's clothing and your clothing and lay on top of her while increasing your own body temperature slowly and steadily. That's the only way to warm her up without putting her into shock. But be careful not to put too much pressure on her body. She's very brittle at this temperature and could literally break into pieces with too much weight put on her at once." Elise said firmly. There was a bit of an awkward pause.

"Okay, I'll do it." Natsu said as a blush started to form on his face. Happy and Elise turned away to give Luna and Natsu some privacy. Natsu took off all his clothes except for his scarf before preceding to undress Luna, discarding their clothes in a pile on the sandy shore of the island. He then wrapped his scarf around Luna's neck and blushed as he gently lay his naked body down on top of Luna's equally bare body, careful not to crush her. Steam immediately formed at the contact of Natsu's skin to Luna's because she was so cold compared to him.

"Cold, cold, cold, cold!" Natsu yelped as he lay on top of Luna's freezing body, embracing her gently.

"Normally I wouldn't allow anyone to see Luna naked, but this is an emergency. Natsu I'm counting on you to revive Luna." Elise said to Natsu, looking away as she and Happy got a blanket from Luna's bag and draped it over the two dragon slayers. Tears threatened to spill from Elise's eyes.

"Please save her!" Elise said as she starting breaking down into tears, grabbing one of Natsu's hands with her paws. It really pained her to know Luna was in such a dire state.

"Don't worry Elise, I won't let Luna die." Natsu said seriously as he patted Elise on the head with his free hand. Happy walked over to Elise and took her paw in his.

"Come on Elise, let's leave Natsu and Luna alone. I know it's hard to leave Luna like this but Natsu needs to focus on reviving her right now. You know how easily he gets distracted. We'll check on them later, okay?" Happy said as he looked into Elise's teary eyes. She nodded and followed Happy away from Natsu and Luna, looking back one more time. In the meantime, Natsu wrapped his arms around Luna more, surrounding her in a warm embrace underneath the blanket, trying his best to warm Luna up. He gradually raised his body temperature while clinging to Luna like Elise told him to do.

"Please Crystal, don't die. I don't know what I'd do if I lost you." Natsu said as he held into Luna tighter. He rested his forehead against hers before kissing it. There was no response from Luna. It was at this moment that Natsu realized just how much Luna meant to him. He didn't just see her as a childhood best friend now, he saw her as his soulmate.

"Luna please wake up. I love you. Don't leave me!" Natsu confessed as tears began to roll down his cheeks from his eyes. He continued to raise his body temperature to the point where he was radiating a soft yellow-orange glow. Slowly but surely, Luna's body temperature was rising and color was starting to return to her extremely paled face. Her breathing and heartbeat began returning to normal. After what seemed like hours, Luna's eyes started to slowly flutter from being frozen open and she blinked. The blanket that had been covering them had burned away at this point.

"Na-Natsu?" Luna said wearily as Natsu got up off of Luna and sat up. He sighed with relief as he wiped the remaining tears from his cheeks. He quickly but gently pulled Luna into his lap and surrounded her in a warm embrace.

"Luna, thank goodness you're awake! I thought I was going to lose you." Natsu said with immense relief as he tangled his fingers in Luna's long, silky light blue hair.

"It's okay Natsu, I'm fine. Thanks to you, I'm alive." Luna said, returning the embrace. Natsu shook his head.

"But if it weren't for you, I would be dead. Thank you Luna." Natsu said as he broke the embrace, placing his hand on Luna's bare shoulder.

"We should get dressed now." Natsu said while Luna blushed as she realized they were both naked. She quickly got off of Natsu's lap and covered herself with his scarf out of embarrassment, her face as red as Erza's hair. Natsu got up and walked over to the pile of clothes and gathered them up, bringing them over to their travel bags. He got out a new set of clothes for both of them from their bags and packed up the clothes they were wearing earlier because they were ruined a bit from the encounter with the dark guild Hell Spawn. He brought Luna her clothes and turned around to give her privacy as he got dressed himself. Luna took off Natsu's scarf and stared at it in her hands. The white scales knitted into it shimmered in the sunlight. Luna buried her face in the scarf and breathed in. The scarf was unexpectedly soft and smelled of Natsu's comforting scent. Natsu stared at Luna indulging herself in his scarf as she clung to it, wrapping it around her still naked body as she enjoyed the luxuriously soft texture.

"You gonna get dressed or what?" Natsu asked, smirking at Luna as she stopped what she was doing and blushed a deep crimson when she realized that he had been watching her.

"Uh yeah. Sorry." Luna apologized as Natsu turned away again and she put down the scarf and got dressed. When she was fully clothed again, she picked up Natsu's scarf and walked over to him.

"Here's your scarf." Luna said reluctantly holding it out to him, averting her gaze to the side. Natsu looked at her then the scarf.

"You know what? I'll let you wear it for a little longer." Natsu said, grinning widely. Luna's eyes widened a bit in surprise.

"Are you sure? After all, it's your most prized possession. I've never seen you without it on." Luna said, double checking with him.

"Yeah I'm sure. I trust you with it. And besides, I could tell you were getting quite attached to it." Natsu said, winking at Luna who blushed furiously.

"Th-thanks. I'll take good care of it." Luna said as she wrapped the scarf around her neck. Natsu stared at Luna beside him with a smile on his face.

"What?" Luna asked as Natsu just shook his head.

"Nothing. It's just that you look really cute wearing my scarf." Natsu complimented Luna as she blushed a bright red. Just then, Happy and Elise came running up to the two of them. Elise tackled Luna in a hug.

"Luna! You're alive! I was so worried." Elise said as tears of joy started streaming down her face. She turned to face Natsu while still clinging to Luna.

"Thank you so much for saving Luna!" Elise thanked Natsu as he grinned, rubbing the back of his head.

"Yeah no problem. After all, Luna saved my life first. So of course I had to return the favor. And besides... there's no way I could live without her." Natsu said as he scratched his chin while blushing. Silence followed as Natsu thought about his confession he made to Luna when she was unconscious. His blush deepened in color the more he thought about it. Elise started to get suspicious.

"Did something happen that I should know about?" Elise asked Natsu accusingly, tapping her foot as Luna frowned at her.

"Elise, stop it. Natsu didn't do anything inappropriate to me. You should know him by now. He's not that type of guy. He would never do that kind of thing to me without my consent. He may not even feel that way about me." Luna said defensively as a disappointed look made its way onto Natsu's face. He was a bit disheartened that Luna didn't hear his confession. Although it was to be expected, she was unconscious after all.

"Nothing happened, Elise, honest! The only thing I did to Luna is what you told me to do. Anyways the world is in danger of being wiped clean of all magic power. We've got to figure out how to destroy this tower and then find and destroy the other towers and Hell Spawn before it's too late." Natsu said as Luna, Elise and Happy nodded in agreement.

"Frostus said that as long as at least one of the cores are somewhat intact, they will be functional. There are four cores, two main and two backups encased in spherical chambers made of curse iron on each tower. And the holes in the spheres are sealed by curse runes that cancel out all magic. He said the iron is enhanced, but he didn't say that it was protected by magic canceling curse runes. Maybe you could melt the iron if you produced hot enough flames." Luna said as Natsu smiled with determination.

"Heh, this is perfect for training. I'm all fired up now! Happy, Luna, Elise you guys better stand back." Natsu said as he smacked his fist into the palm of his other hand. Luna took Happy and Elise in her arms and moved a safe distance away so that they wouldn't get in his way. Natsu then started attacking the tower's sphere chambers with his fire. Even at a distance, the three of them could feel the intense heat of Natsu's flames. After what seemed like hours of Natsu attacking the spheres nonstop, they still remained unscathed. They were glowing yellow-orange from the heat, but the metal wasn't melting.

"Too bad Gajeel isn't here. He could just eat his way through the metal." Happy said as Natsu continued throwing flame after flame at the tower's spheres.

"How about you try activating your dragon force." Luna suggested as Natsu paused for a moment.

"You know, that's a great idea Crystal. Thanks!" Natsu said as he transformed into his dragon force form, red scales appeared on the left half of his face and body, and yellow belly scales formed on the left half of his stomach. A black dragon horn grew from the left side of his head as his left arm and leg morphed into dragon limbs. Finally, a large wing sprouted from his left shoulder blade. He started attacking the tower again, but with more ferocity and power. The heat from his attacks dramatically increased. Eventually, the metal slowly started to melt.

"It's working Natsu!" Luna said as Natsu continued to attack the spheres. After a few more hours of blasting the spherical chambers with fire, they were finally destroyed enough to get at the cores. Happy and Elise grabbed Natsu and Luna and flew them up to the cores so they could grab them. Luna activated her dragon force form. White scales formed on her forearms and legs, her fingernails and toenails elongated into sharp claws, light gray antler-like horns grew from her head, wings made of crystal-like feathers sprouted from her shoulder blades, and a white-scaled tail with a large tuft of light grayish blue fur at the tip sprouted from right above her ass. In her dragon force form, Luna was basically a humanoid version of Prisma, her dragon mother.

"Let's destroy these things!" Natsu said to Luna who nodded her head in agreement. While both of them were in their dragon force forms, Natsu and Luna ferociously attacked the cores, one by one, with fire and ice until the cores were reduced to dust. Exhausted, Natsu and Luna reverted back into their human forms.

"Phew! Glad that's over. I'm exhausted... and starving." Natsu said as he fell backwards onto his back onto the sandy beach.

"I wish we could rest, but we should get moving. We have no time to rest if we want to succeed in stopping Hell Spawn from achieving their goal." Luna said as Natsu sat up.

"You're right, Luna. I can't let those bastards succeed. They had the guts to desecrate Fairy Tail's sacred island by placing their stupid tower on its shore. And I especially can't forgive them for harming you!" Natsu said, burning with rage.

"Calm down Natsu and let's just think for a moment about how we're going to go about this. You managed to melt the spheres that encased and protected the cores so we could obliterate them, but we've got to figure out a faster way to destroy those sphere chambers. Melting them just takes too much time and energy." Elise pointing out a big problem.

"Yeah, at this rate we won't be able to destroy all the tower cores in time before Hell Spawn detonates them. We still have to find the other three towers before we can even destroy them. Frostus said that each individual tower has the power to nullify magic across the entire world. And if any of the cores are somewhat intact, they're still functional. If we don't completely obliterate the cores of all four MNTs, the earth will be void of all magic." Luna said as her mind scrambled to figure out a faster way to destroy the spheres that protect the cores. After a moment of thinking, Luna got an idea.

"Hey, I think I figured out a way to destroy the protective spheres faster. If I freeze the spheres while in my dragon force form then Natsu immediately blasts them with his flames while in his dragon force form, the iron might crack from the intense change in temperature over a short span of time. We can break through the spheres faster to get at the cores. The spheres may be made of enhanced curse iron, but the general laws of physics still apply to them. We may have to repeat the process several times, but it shouldn't take as long." Luna said as Natsu came up to her, placing his hands on her shoulders.

"Luna, you're a genius! I'm all fired up now! Alright everyone, let's go ruin Hell Spawn's plan!" Natsu said enthusiastically as he let go of Luna's shoulders and thrust his fist into the air.

~Short Time Skip~

"Ugh, I forgot... we have to... urk... take a boat... back to... the mainland." Natsu said as he hung his head over the edge of the small boat.

"We're... almost... there." Luna said as nausea consumed her too. Shortly after, the boat reached the shore of the mainland. Luna and Natsu practically teleported off the boat, they got off it so fast. They were thankful to finally get off that horrid boat. The four of them then began their unofficial quest to stop Hell Spawn from executing their global magic nullification plan.
