A/N: Oh heck yeah. Here it is, y'all, the formal declaration of war. It. Is. On.

It was a bloodcurdling, ear-piercing shriek of pure feminine rage that made all of Fairy Tail and their friends from Sabertooth jump out of their skins. The scream was almost instantly identifiable as belonging to one Lucy Heartfilia.

Some of the members, the ones who had been on the receiving end of Lucy's fearsome rage regularly (read: Natsu and Gray) decided it'd be best if they ducked down and hid for a bit, just in case they had done something to set Lucy off unknowingly.

The two guilds had already dealt with three brawls involving half the guild, various boasting contests that threatened to turn into yet another brawl, and an unnecessary musical performance. Gajeel and Orga thought it was a brilliant idea that they should sing a duet. Laxus had zapped Gajeel while Juvia sent a Water Slicer at Orga.

Everyone else was grateful, because honestly, the two sounded like someone was drowning a bag full of pissed off, helium-drunk kittens while beating a metal roof to death with a squeaky toy.

Now what was going on?

"STING EUCLIFFE, YOU BLOODY JERK! I'M GOING TO RIP YOUR LIMBS FROM YOUR BODY SLOWLY WITH A PAIR OF RUSTY PLIERS AND A GALUNA ISLAND DEMON'S ARM, BOIL THEM IN SOME OF ERIK'S POISON UNTIL THERE IS ALMOST NOTHING LEFT, SHOVE THE REMAINS DOWN YOUR THROAT, AND FEED THE BONES TO HAPPY FOR DINNER, SO HELP ME MAVIS! IF I GET MY HANDS ON YOU, YOU BETTER START WRITING YOUR WILL!"

Something had happened to set off their normally happy Celestial Mage. Rogue, Yukino, and Levy, who had all been bonding over books, turned unamused stares on the cackling master of Sabertooth. They hadn't really thought much of it when Sting had come bolting in not even a handful of seconds ago, diving over a table and hiding just before the guild doors flew open with a resounding crash.

They should have known he was up to something rotten.

Lucy stalked in like a dragon in search of prey. Maybe they shouldn't have let the dragon slayers adopt her; their traits seemed to be negatively affecting her.

Her rage was a little less believable when she looked somewhat akin to a drowned river rat. Her blonde hair was plastered to her face. Her shoes squelched as she dripped her way across the floor leaving puddles in her wake. And she just had to be wearing a white shirt that day. Lucy's hot pink bra was on full display for the entire world to see but she was too angry to even care.

"Eucliffe…"

Sting grinned as he stood up, casually stretching as if Lucy's rage wasn't able to fluster him in the slightest. "What's wrong, Heartfilia? Can't take a joke? It was just a bucket of water, not something to get all wound up about!"

"I happened to like this shirt, jerk!" Lucy shrieked as she stomped forward, intent on ripping his eyeballs out and shoving them down his throat. "It is on," Lucy snarled, her hands curling into claws as Mira managed to hold her back from throttling Sting. But only just.

Sting's sharp fanged grin threatened to send her over the edge however. "Sure thing, Blondie, but are you sure you want to get tangled up in a prank war with me, the Great Sting Eucliffe?"

"Yes," her snarl was deeper and more feral this time. "Simply so I have can the pleasure of gloating over you."

Yep, she was going draconic. Time for an intervention. Laxus easily grabbed his soaked sister from Mira's arms, physically restraining her from spilling Sting's blood all over the floor, and shot Sting an annoyed look.

"Let me go Laxus! I'm only going to kill him a little bit! Just a little! Not very much! He doesn't really need his ears, does he?" Laxus sighed and tucked his bucking and squalling sister under his arm. "I'm going to take her home," he said calmly, ignoring Lucy's increasingly creative threats against Sting and Laxus. "And Lucy, that's not physically possible. Eucliffe, I'd be careful if I were you." A dangerous twinkle lit Laxus's eyes. "Lucy isn't known for being merciful. Especially to people who piss her off."

"Hang on, big guy, everyone knows a war can't start without a formal declaration, so if you could put your sister down…?"

Laxus sighed, wondering how in Earthland this blond idiot had managed to become the master of a guild, and set Lucy down carefully on her feet. Sting smirked. Oh yeah, he was going to show her who the King of Pranking was!

"I, the Great Sting Eucliffe, challenge you, Lucy Heartfilia, to a prank war! If you're sure you wish to accept the challenge, the loser will be whoever gives in first!"

Still dripping, Lucy surprised him by giving him a fanged grin reminiscent of a dragon. "Oh, I'm more than ready to face you, Eucliffe. The real question is are you sure you aren't getting in over your head?"

"No way! It's on, Heartfilia!"

Both mages shook hands, wicked grins on both sides.

Sting put his hands behind his head as the Sabers walked home. He was fully confident in his ability to win a prank war against the blonde Celestial mage. She was just a little girl. What would she know about pranks? He voiced his thoughts aloud to Rogue. Who gave him a questioning look.

"Really? That's the assumption you're going with? Miss Lucy has older brothers. Dragon slayer older brothers," he stressed. "Plus she is a high class lady. From what I've heard, they would pull pranks but had to be super stealthy about it. She no doubt has more experience and a better head on her shoulders than you do."

"Way to have faith in me, Rogue," Sting muttered.

"I know you can win, Sting! You're the best! That Fairy girl doesn't stand a chance against you!" Lector cheered. Frosch cheered too. "Fro thinks so too!"

"To be honest," Yukino said slowly. "I think Lucy-sama has a better chance at winning than you do, Sting. She just seems more capable."

"Fro thinks so too!"

Sting threw his hands up. "Does no one here believe I can win against Blondie?"

Silence from his guildmates was his only answer. "Geez, guys, thanks for the vote of confidence." Sting sighed, rubbing his forehead. "C'mon, let's get home. I have a prank war to win!"

A/N: And so it begins! What will Sting's first prank be? How will Lucy retaliate? And who will win? If y'all have any prank suggestions, please feel free to share them in the reviews or a PM!
