Hi everyone! Not much of a headcannon but I found the idea to be fun! Enjoy!

Chapter 2: Barrels Upon Barrels

It was a peaceful afternoon in the Fairy Tail guild hall, no brawls, no arguments, just Makrov and his beer.

The reason for this quietness? The S-Class exams were coming up and everyone was out training or taking as many jobs a possible. The only ones still in the guild were the ones who weren't mages (Kianna) or had enough power as is (Guildarts).

Then the doors were blown open and in came the residential flame-eater and his "cat".

"WE MADE IT BACK ALIVE."

"NATSU! HOW MANY TIMES DO I HAVE TO TELL YOU THOSE DOORS ARE EXPENSIVE!"

Natsu laughed, and walked over to the bar.

"Hey Kianna, I'm starving. Could I get a lunch platter?"

"Of course Natsu, one 'flame quenching lunch platter' coming up!"

"Don't forget my fish, Aye!"

So then Makrov, Guildarts, Natsu and Happy fell into regular conversation. They were talking about life (Guildarts), fish (Happy), guild expensses (Makrov) and missions (Natsu).

"Say Natsu, anything interesting you found on your mission this morning?" Guildarts inquired.

"Hmmm, oh yeah. We ran into Cana on the way back, she was drinking down an entire bar."

"Aye! And when she was done, I said "you really can't drink any more? Lightweight." And then we ran as fast as we could before she killed us, hehe."

The few people that heard this, sans Natsu, looked at the blue exeed incredulously. Everyone knows that there are three things that can get you killed in this guild, ruining Erza's cake, making Mira cry and insulting the brunnette's drinking abilities.

"Oh yeah, that was a few hours ago, Cana should be back by-"

Natsu was interrupted by said mage kicking open the guild doors, red faced and ready to kill a blue cat.

"THERE TOU ARE YOU LITTLE SHIT."

"AHH, NATSU SAVE ME."

"Oh my baby girl! There you are!"

So a stupid yet hilarious chase ensued with Guildarts trying to hug his daughter, Cana trying to kill Happy and Happy flying away from both of them.

"Hey Natsu, here's your food." Kianna said as she came over with a large platter of assorted foods.

"Oh thanks Kianna! You're the best!"

Natsu quickly started inhaling the food presented in front of him.

Kianna giggled at the fire mage and asked, "Could you tell me why Happy is being chased by Cana?"

Natsu looked up and replied, "On the way back, we met in a bar and Happy called her a lightweight."

"But why would he say that? What reason could he have to anger Cana?"

"Because she only finished 3 barrels, I nearly drank a bar out a business."

The chase paused, Happy snickering having not being caught, while Cana and Guildarts looked at him like he was crazy.

"YOU WHAT?" The few people in the guild, sans Natsu and Happy, screamed.

"Oww, dragon ears here." He mumbled while covering said ears, "But yeah, I was coming back on a mission and decided to see if that bar had any food. Then a group of guys, were having a drinking contest. Normally I would stay out but they bet 1000 jewels on the winner."

"So you join a bunch of random people in a drinking contest?"

"Yeah, the bar thought it would be funny to fund it, and so they said their entire beer store would be available for us."

"Aye! They started and they all teamed up on Natsu, taking turns and switching out when one of them felt woozy." Happy joined in with a fish in his mouth. "Took a long time to finish, apparently only 1 barrel remained in the cellar."

The audience took a bit to comprehend this information, Natsu not only drank against but judging from his attitude, won against 4 men.

"HAHAHAHA, no way, this lightweight?" Cana laughed, "I bet 20,000 jewels that I can drink more than him. Let's go Natsu, right here right now."

"Sure, I'm all fired up!"

Makrov sighed while rubbing his temples. This was going to cost a lot of money.

"Master, are you okay with this?" Kianna asked worryingly.

"No my dear, unless they pay for everything they drink."

"I'll fund it" Spoke Guildarts "Day was getting boring and I really want to see if Happy is exaggerating or not."

And with that, Kianna, with the help of Makrov, went down to the cellar to bring up heaps of beer barrels (Guildarts keeping a mental tab of how much it'll cost him). As this was happening, several members came back and decided to place some bets on this spectacle. Most of the bets were placed on Cana, seeing that Natsu has never had a drop of alcohol. The only ones who did bet oh him were that dragon slayers and Happy.

"Alright, I want a fair battle. So no hitting the opponent or utilising magic." Guildarts announced. "Now, begin!"

The two contestants quickly brought the beer to their lips, chugging back the beverage. The guild was cheering them on, seeing that their money was at stake. A good amount of them were shocked to see Natsu drinking on par with Cana. After an hour, the cheers stopped, everyone sat around the guild doing whatever waiting for the contest to finish.

Evening came and a large mountain of empty barrels amounted. If you were to look at the contestants, Cana was shaking a lot. Meanwhile, Natsu looked like he was drinking water, no flush, no jumbled movement, nothing. Eventually, the card mage started swaying and...

"Natsu is the winner!" Happy calls as Cana falls over.

The guild was shocked (minus the dragon slayers, who were collecting their large pile of winnings). How was this possible? They have never seen Natsu drink alcohol and yet he just out drank the second heaviest drinker in Fiore!

"Wait, how?" Called Mira, who having experienced Cana's alcoholism the most, bet a good amount of money on her.

Natsu finished his barrel and set it on top of the others, replying with "Simple, dragon slayers naturally have high poisson resistance, and my internal fire burns away even more poisson."

"Then why don't you or the other slayers ever drink?" Cries Macao, having also lost a lot of money from betting.

"I can answer fer ya Salamander," Ganjeel spoke up, "As the iron dragon slayer, oftentimes the alcohol can't even get into the blood. Back in Phantom Lord, I tried some beer and spat it out. It tastes terrible and why drink it if you aren't affected by it."

"Yeah, that's the gist of it," Natsu said as he headed towards the Strausses, "anyways Lisanna, let's go barrel surf!"

The young silver haired mage giggled and went along with him. She did enjoy playing around with him like this.

"Count me in!"

"A REAL MAN PLAYS RISKY SPORTS!" Elfman cried setting up his own surfing.

So the evening went along with much energy. No brawl happened, as everyone was having fun surfing or hiding on the second floor. Cana was taken to the infirmary to sleep off the alcohol. When she woke up, there was a note written to her explaining what happened and how Natsu won.

The lush laughed, before getting up and heading to the library. She found a book with poisson resistance spells and started practicing, motivated at her new obsession to beat the fire mage. After all, it's not every day that you get beaten at what you're best at.

She smirked at the thought, her mind slowly drifting towards the thought of a drunk Natsu.

The idea was both foreign and attractive.

Alright! That's chapter 2! How was it? Please review and share to your friends.

A bit of Cantsu at the end there, as you can see I will add some kind of shipping comment at the end of each chapter.

I got this idea from when Natsu was fighting Cobra and he said something about burning away the poisson. So I thought that since alcohol is a toxin, then he should be resistant to it. Then I remembered Ganjeel's iron scales make it hard for toxins to be absorbed into his body, and that Wendy's body probably automatically dispels toxins. I decided to give high alcohol tolerance to all dragon slayers, giving the explanation that the naturally have high toxin resistance and their element can help out further.

Anyways, Peace!
