Holding hands.

If holding someone's hand (especially if the said person is the same gender) makes him gay, it is better than being alone.

To Know You

Gratsu Week 2024: Day 2 Prompt - Magic

“This is your fault,” Gray snapped at Natsu as once again he failed to produce anything more than the most pitiful flame that wouldn’t have lit a candle. The sight of a flame flickering on the end of his finger, and the instinctual flinch as he waited for the pain to set in made his weak control on the magic disappear entirely, and he huffed and clenched his fist. There’s no way we can fight like this, he thought, eyeing the Dragon-slayer who was sat beside him, looking decidedly worse for wear, with cuts and abrasions everywhere and his left eye half-closed with swelling. Concern threatened to bubble through his irritation, but then he remembered that they were in this mess because Natsu hadn’t watched what he was destroying, and as it turned out the weird contraption in the corner of the room had been more than decoration.

“You’re trying to control it too much,” Natsu said, seemingly ignoring the accusation and if he was worried by the fact that they were currently hiding from the mage whose study he had trashed, and were running around with their magic switched and no immediate way to undo the transfer it didn’t show.

“What?”

“My magic,” Natsu lifted his hand and curled his fingers into a fist, and there was the first crack in his calm as a little flurry of ice shot from his fingers rather than flame. “You don’t mould my flames like you do your ice.”

“What do you know about my ice,” Gray demanded. He missed his ice. He could feel Natsu’s fire and warmth just under his skin, and it set him on edge. It wasn’t his. And worst when he’d grabbed the Dragon-slayer to haul him out of the study, Natsu had felt cool to the touch, and it had been so wrong that he had almost dropped him. As much as he had taunted the flamebrain for always been too hotblooded, over the years that warmth at his back or at his side had become a comfort. Natsu was supposed to be warm. He glared at Natsu, unprepared for the Dragon-slayer to meet his gaze directly, or the emotion in them – which he was not ready to put a name to, not with everything threatening to crash down on them.

“I know you.”

A simple truth.

 Natsu did know Gray, and while the Ice mage knew it wasn’t what the other mage had been implying, it suggested that he should know the Dragon-slayer just as well, and right now, he wasn’t sure he did as the strange warmth stirred through him.

Am I that far behind…

He didn’t get chance to ask as the door and part of the wall to the room where they had taken shelter blasted inwards, showering them with dust, rubble and the sensation of roiling, dark magic pressing against them. Forgetting all about the fact that he still didn’t have a handle on Natsu’s fire, Gray was immediately on his feet and moving to cover the Dragon-slayer, ignoring the sting of his own wounds. “Not a chance,” he said, standing in front of Natsu who was still pushing himself to his feet, wobbling in a way that suggested there were injuries Gray hadn’t been aware of, and the irritation built a little higher. He channelled it into a glare as the mage glided through the opening he had created, gaze shifting between the pair of them, and Gray tensed as he felt the magical pressure building.

It burst, roaring towards them. A fan of shadow-tinted spears that he had already seen pierce rock, and he froze, he couldn’t shield them from this and Natsu’s fire wasn’t his and…

“Ice Make: Shield!” Natsu roared, and the world in turn of Gray turned blueish-purple a split second before the shadow spears reached them. He squeezed his eyes shut, bracing for the pain, hoping at least his body would protect Natsu, because there was no way the Dragon-slayer could’ve shielded them completely.

The pain didn’t come.

He opened his eyes, mouth falling open as he took in the shield glistening in front of him. It wasn’t as sturdily built as his own would be, and already it was cracking, falling apart from the dozens of impact sights where the shadow spears had struck.

But it had protected them.

Natsu had protected them…with Gray’s magic.

He could feel the Dragon-slayer at his back, vertical now, but almost leaning against him as though that effort had exhausted what strength he had. Gray was about to turn to check on him, when a strangely cool hand came to rest on his shoulder, allowing him to feel the tremors now wracking Natsu. “Why are you fighting…?” Natsu’s voice trailed off, his hand disappearing, and Gray was aware of the sound of the Dragon-slayer slumping to the ground behind him, but he couldn’t move because the shadows were building again, a deadly wave that Natsu couldn’t protect them from this time.

But…

He curled his hands into fists. Why am I fighting? He thought back to the image of Natsu rushing forward to take the blow that had been intended for him, taking the brunt of the damage, before being flung back into him which had sent them both stumbling back into the device that had flared golden as it switched their magic.

For us, for Fairy Tail…for Him.

Something stirred beneath his skin, his hands flushing hot. I’m fighting to protect what’s precious to me, he thought, and the magic that wasn’t his responded, flames beginning to wreath around his hands. There was a burning in his chest, a fire igniting, and rising in his throat. Smoke began to rise as he took a step forward.

Not enough.

There was no sound from Natsu, and it was taking everything he had not to turn around. Protect him. He grabbed hold of that thought, hoarded it like a dragon gathering gold, and the flames responded. They were spreading now, from head to foot, until he felt like he was drowning in Natsu’s presence, and he breathed it in, eyes locked on the other mage. I do know you, he thought, and a wild grin crept across his face and with a shout he charged just as the shadows swept towards them, and the fires roared with him.

“Fire Dragon’s Sword horn!”

Natsu is bad at dating. Gray is slightly less bad so Ezra forces him to help. Turns out, it’s their first date all along. Enjoy!

If rival is someone who is worth fighting, then let them fight. Otherwise, they will not be friends.

Natsu and Gray start bickering again, and Lucy, as usual, is exasperated to see that. Cue Mirajane and Happy being casual as usual.

It's a Promise

Gratsu Week 2024: Day 1: prompt - Caught

****

War.

As soon as the word had been muttered, it had settled like a cold weight in the pit of Gray’s stomach. People died in war, especially magical wars where a single mage could wipe out countless others with a single attack.

Especially a war against a Zeref.

He’d looked at Natsu then, but if the Dragon-slayer had felt an echo of his own fear it didn’t show on his expression. He envied him in that moment. Aren’t you afraid? He wanted to ask. Do you feel ready for this? They had been through hell and back, had spent a year apart growing stronger and stronger, striving towards their own goals and some distant future point, that now lay beyond the gaping chasm that was the approaching war. In an instant, and under the weight of a single word, Gray felt as though all that growth had been stripped away from, and everything he held dear once again teetering on a knife edge; and yet Natsu was stood there, fierce and ready to fight, seemingly untouched by the fear gripping the Ice Mage.

It would be easy to believe it, and part of Gray wanted to, because to see Natsu determined and burning bright was the beacon that had guided them to victory so many times in the past. Not that he would tell the Flamebrain as much, it would go to his head. He wanted to see the fierce grin, the fire in the olive eyes, and the clenched fist and believe that Natsu believed they were going to win this war. He wanted the Dragon-slayer to stand there and tell him that they were going to survive this, because he would believe it, because he always believed Natsu when he spoke like that, as though the Fire Mage had the power to will victory into being just with his words.

He wanted to believe it…

…but he couldn’t…

Because he knew Natsu just as well as he knew himself, and the time apart hadn’t changed that. He could see the edge to the grin, the trace of uncertainty that only those who knew how to look would see. He saw the way Natsu fidgeted with the bandages he had kept wrapped around his arm since their return – his secret weapon he kept claiming; but now he was clinging to it, as though praying that it would be enough.

And he saw the moment that Natsu slipped away amongst the crowd, using the distraction of the organised chaos as Mavis and Makarov marshalled the guild and began laying out their plans for the war to come. Gray knew he should be listening, that they both should. But, the Dragon-slayer was leaving, threatening to take with him the Ice mage’s courage, and there was something about the way Natsu was moving, the expression on his face as he sought out Happy that terrified the Ice Mage and so he followed. He ignored everything else around him. Erza would fill him in on what he missed, and he’d even risk her ire for not having paid attention.

Realising that Natsu with Happy in tow were hurrying for the exit, he dashed forward, expertly weaving between the gathered guild members with a skill honed by years of brawling in this very hall. It let him back it to the steps leading to the door, just in time to catch up with the Dragon-slayer, and not wanting to cause a spectacle he dashed forward and reached out, fingers closing on the Dragon-slayer’s elbow, staying his escape.

“Natsu?” What are you doing? Where are you going? There was too much he wanted to ask, and even more that he wanted to stay. Stay. Fight beside me. Lend me your courage. And in the end, he settled for squeezing Natsu’s elbow and repeating his name, the question clear in his tone.

“Gray…” Natsu sighed, not exasperated, but almost despairing. As though he wished he had been caught by anyone else, and that hurt. But, then the Dragon-slayer glanced at Happy. “Wait for me outside.” The Exceed nodded, looking meaningfully at Gray although the Ice Mage wasn’t sure what he was supposed to know, before Happy moved away, leaving the two of them stood there, frozen on the steps. A bubble of quiet seeming to wrap itself around them, as Natsu lifted his head and met the Ice Mage’s gaze and held it. There was a shadow in those eyes, not of fear or defeat, but a resolve that was just as terrifying as it would be to see Natsu scared of what to come.

“You’re leaving…” It wasn’t a question. More like an epiphany so sharp and sudden, that there had been no choice but for those words to slip out. You’re leaving us? You’re leaving me? No, that wasn’t right. Natsu wouldn’t leave them, not without reason and he swallowed, gazing searching into Natsu’s eyes, searching for an answer, watching the way the Dragon-slayer fidgeted with his bandages yet again; and it was like fireworks going off in the back of his mind. “…No, you’re going after Zeref, aren’t you?”

He knew he was right, even before Natsu froze, staring at him wide-eyed like a deer caught in a magic-car’s lights. The lead weight of fear turned to anger, and he wanted to scream and shout and call Natsu ten kinds of idiot for trying to fight alone, for thinking he could win along. Yet, the protests wouldn’t come, because Natsu’s expression had cleared and the shadow was gone, and instead there was a fire in the Dragon-slayer’s eyes that he recognised.

It was the same fire that had allowed them to be standing here. The one that had seen them through countless fights, and troubles; the one that Gray would never admit, but he had missed intensely over the year apart.

The same fire that had made it the easiest decision in the world to return to Fairy Tail.

“Gray…” Natsu had shaken off his shock at being caught, and suddenly Gray didn’t want to hear it, whether the Dragon-slayer was going to be honest or not. You’re going to be fighting with us, that’s all that matters. It wasn’t, and this was a terrible idea. And part of him still wanted to scream and shout that, and called Natsu an idiot, but instead he squeezed Natsu’s elbow one last time.

“Promise me…”

“Promise you?” Natsu asked.

“Promise me that you will come back,” Gray demanded. He wasn’t asking for victory, he didn’t know how powerful Natsu’s secret weapon was. He didn’t care. Victory would happen, or it wouldn’t. If it didn’t then they would find another way; as long as Natsu came back to them. To him.

“Gray,” Natsu pulled his arm out of the Ice Mage’s grip, only to rest his hand on Gray’s for the briefest second. “I will come back.”

It’s a promise.
