Here's the second chapter. Enjoy!

P.S Sorry for any mistakes I make in advance.

It was a normal day at the Fairy Tail guild hall.

Well, as normal as the Fairy Tail guild hall could get.

And normal at Fairy Tail could only mean one thing.

Fights.

Natsu glared at Gray as he said, "Put on some clothes you pervert!"

Gray glared back at him with equal amounts of vehemence. "Why don't you get a brain first flamebrain!"

"Droopy-eyes!"

"Squinty-eyes!"

A few more insults later, Gray and Natsu charged at each other, fists flying through the air.

Lucy sighed as she sat at the bar while watching Gray and Natsu have another one of their pointless fights. At this point in time, it had become normal for her to see them fight like this all the time. In fact, she would have thought something was wrong if Natsu and Gray weren't fighting.

Suddenly, a low voice shouted out, "It takes a real man to win this fight!"

Elfman suddenly joined in the fight. Soon enough, almost every member of Fairy Tail was fighting each other.

As Lucy watched the fight from her seat at the bar, she remembered when she first stepped foot into Fairy Tail. When she, Happy, and Natsu arrived at the guild, Natsu immediately started a fight with one of his fellow guild mates. Afterwards, it had turned into a full out guild brawl.

Lucy smiled fondly at the memory; some things just never changed.

Suddenly, Lucy was broken out of her thoughts. While Natsu and Gray were fighting, one of the tables in the guild hall flew up…

And hit Erza Scarlet.

Well, more specifically, her cake.

Erza, who was currently at the bar sitting next to Lucy, stared in horror as her strawberry shortcake fell to the ground and was crushed by the table. Erza whipped her head around and glared at Natsu and Gray. If looks could kill, hers would've killed them both a hundred times over. When they spotted her, the two boys immediately stopped fighting, nervously glanced at Erza, and gulped.

The boys hugged each other in fear as Erza slowly walked towards them and said in unison, "We're sorry Erza!"

Erza said nothing as she grabbed both of their heads and bashed them together. Natsu and Gray immediately fell down in a heap of tangled limbs.

Lucy stared at her nervously and whimpered, "She's scary."

Happy, who happened to be next to her, sweat dropped and said, "Aye…"

As Erza loomed over the two boys, she angrily said, "You two need to learn when to tone things down a bit. Because of that, we're going on a job that involves no destruction. Lucy!"

Lucy eyes widened a bit when Erza yelled out her name. She responded nervously to the angry Erza. "Y-yeah?"

"Please choose a simple request for us to do that requires no fighting."

"O-okay."

Lucy was surprised that Erza wanted her to pick a job for them. Actually, she was surprised that Erza was even taking them on a job. Usually, Erza would just yell at them and beat them up. Lucy would've questioned Erza's decision, but from experience, she knew it was best not to question Erza when she was in a bad mood. The best thing to do was to follow her orders without question, especially if the reason for her bad mood was cake related.

As Lucy scanned the request board for non-fighting related quests, Natsu and Gray were arguing with Erza.

"Aww man, do we have to go? I just got home from a solo mission a couple days ago!" whined Gray.

"But it's gonna be so boring if we don't get to beat up anyone!" Natsu complained.

Natsu and Gray spouted off more complaints ranging from needing to go shopping, to simply not getting to beat anyone up. Erza decided she had enough. She grabbed both boys by the scuff of their shirts (well, in Gray's case, his hair) and glared at them. Both of the boys paled and immediately shut up.

"Both of you will be going on this mission with me and there will be no complaining. Do you understand?"

"Yes ma'am." Gray and Natsu said nervously.

Lucy suddenly grabbed a request off the board and said, "Hey Erza! I got the perfect job for you guys!"

Erza let go of the boys and went over to Lucy. She took the request out of her hands. After reading it, she grinned and declared loudly, "This is perfect Lucy!" Then, Erza directed her gaze at Lucy. "Say, do you and Happy want to tag along with us too? You probably need the money."

Lucy glanced over at Erza and thought for a moment. It wasn't like she didn't want to go on the job. In fact, she actually really needed the money. But, the only problem was, well….her team. They weren't the calmest people to go on a job with. It seemed like no matter what job they took, something would always happen, whether it be fighting a dark guild or them destroying another town…

But, the request had no fighting involved, it was straightforward, and it was simple. That couldn't go too badly right? Plus, the reward was 500,000 jewel. That was a lot of money for such a simple mission.

Lucy sighed internally. She was probably going to regret the decision, but she really needed the money; her rent was due soon. "I'll go with you guys."

"Great! How about you Happy?"

"Since Natsu's going, I'm coming too."

"Very well. Everyone pack up. We meet at the train station in-" Erza was suddenly cut off by a loud voice.

"This is your fault Gray! Now we have to go on a stinking mission that involves no fighting!"

"If I recall, you're the one that started the fight and destroyed Erza's cake! It's your fault that we have to go on this stupid mission!"

Erza marched over to the arguing wizards and said, "I said no complaining. Do I need to remind you again or will you keep that in mind?"

"Y-yes Erza."

Gray sighed as he knew there was no way to get out of the predicament he was in. He decided to give in and ask what the mission was. "Hey Erza!"

"Yes Gray?"

"What's the mission anyways?"

Erza glanced at the request and said, "We're supposed to retrieve some materials for some scientist."

"Sounds easy enough."

Then, Natsu groaned very loudly. "But there's gonna be no-"

Erza glared at him. For once in his life, Natsu decided to be smart and shut his mouth. Then, Erza scanned the group with a threatening glance and said, "Are there anymore comments?"

There was silence from everyone.

"Very well then, let's not waste any more time then."

With those words, Fairy Tail's strongest team made their way to the train station to take on their job.

"Ugh….I wish Wendy was here."

Lucy glanced over at Natsu who was lying on the chair and suffering from his extreme motion sickness. She sighed. I guess that's one thing I hope will change...

Gray, who was sitting on the seat opposite of where Natsu lay, looked away from the window he was looking out of, sighed and said, "How many times do I have to tell you Natsu? Wendy is out on a job with Team Shadow Gear and can't come with us right now. Plus, remember what she said? If she casts Troia too many times, it'll lose its effectiveness."

"Still…."

With a straight and serious face, Erza said, "Why don't I help you out instead since Wendy's not here?"

Natsu's face immediately paled. He recalled the last time Erza "helped" him out with his motion sickness problem. He had felt so much worse afterwards. "No, no," he groaned. "I'm fine."

Lucy said, "Well, we'll get to our destination in about thirty more minutes."

Natsu groaned, "Ugh..."

Gray smirked at Natsu's current predicament. "Hah! You're so pathetic Natsu."

Natsu glared as best as he could at Gray from his lying position. "Oh… yeah? Wanna go? I can…take you on any day!"

"Says the one that weakness is moving vehicles."

"Says… the one that's not wearing any clothes."

Gray looked down in surprise as he saw that he indeed wasn't wearing any clothing. "Gah! When did this happen?!"

After that incident, the team spent the rest of the ride in silence, all of them mentally preparing themselves for the job.

Suddenly, a voice rang out saying that the train had reached the stop. The team got off the train with Erza dragging Natsu behind her. Immediately, Natsu jumped up in happiness. "Finally! I'm on solid ground!"

Lucy watched from the side in amazement. "It's a wonder on how he can recover so fast…"

"Aye…" agreed Happy while nodding his head.

Gray's voice suddenly broke Lucy out of her thoughts. "Hey Erza, where do we need to go?"

Erza took out the request paper and glanced at it. "It says we need to go to a laboratory at the far side of town."

"Great, let's get going."

A cloaked figure stood at the side of the train station watching the Fairy Tail wizards discreetly.

He frowned to himself. Why were they here? Did they find out about our plan?

Then, he shook those thoughts out of his head. No, that isn't possible. No one knows about us. We've been so careful.

Then, he heard a voice. It was one of the fairy brats. "…need to go to a laboratory at the far side of town."

That was where the scientist lived. His eyes widened a bit. Did the scientist find out? Or did he just send out a normal request?

He weighed his choices carefully. He could continue on with the job. A couple of fairies wouldn't make a difference. But, there was always that what if factor. After all, in the past, the fairies have always come out victorious even with all odds against them.

The other choice he could make was to inform the master; it was better to be safe than to be sorry. After all of their preparation, all of their planning, it couldn't go to waste now. But, it would delay them. That meant that if the scientist had found out about them, he would have more time to prepare.

He watched the Fairy Tail wizards a moment longer before making his decision. He grinned and vanished into thin air, leaving no evidence of him ever being there.

It looked like he would be telling the master after all. It was better to be safe than sorry. And what were the chances of the scientist finding out about them? If anything, all he would have heard about them was their previous work. Also, the wizards he had hired most likely didn't have any knowledge of their plans and were just here to help out the scientist with whatever task he needed them to do.

Plus, what could a couple of fairies do to stop them?

The team walked through the town, only pausing to ask for directions. After about 20 minutes of walking, the team finally made it. Or they all thought they made it at least.

Everyone stared at the small house in front of them. It wasn't too impressive and it most certainly did not look like a place a scientist would work. Instead, it looked like a family home; a very small family home. They all stared at it for a few minutes before Lucy asked the question that was on everyone's mind.

"Hey guys, are we sure this is the right place?"

Erza responded back. "I'm sure this is the right place, but…it doesn't really look like a place a scientist would work."

Gray nodded in agreement. "Yeah, I'm pretty sure scientists usually work in labs and this doesn't really look like one."

Natsu said excitedly, "Maybe this scientist had a secret lab inside his house! That would be so cool!"

Erza said, "Well that could be a possibility. There's only one way to find out." Then, Erza walked up to the door and knocked.

Inside, a voice yelled out, "be there in a sec!"

Then, the door opened revealing a sight that would shock them all. A short, smiling, teen looking around the same age as them had answered the door. He had white hair, pale skin, hazel eyes, and was wearing a lab coat outside of a blue sweater. For his bottom, he wore black gym shorts with a white strip running down them and blue flip-flops. Everyone stared at the strange-looking kid. He wasn't exactly what they had in mind when the request said "scientist". Suddenly, the teen spoke. "heya, how may i help you guys?"

Erza stepped forward. "We received a request to gather some materials for a scientist and were told to come here. Is this the right place?"

The kid scanned the over the group with calculating eyes. His gaze paused when he saw the Fairy Tail mark on Lucy's right hand. The kid's smile widened. "well then, you guys must be the fairy tail wizards i asked for. come on in."

"by the way, the name's sans. sans the scientist."

Author's Note:

Disclaimer: I don't own Fairy Tail and Undertale

And second chapter done! For some reason, this chapter took forever to write. Probably because of how hard it is (for me at least) to turn an anime into a story format...so if you don't like the way the Fairy Tail stuff is written, that's probably why.

On another note, sorry if this second chapter seemed kinda boring. There'll be plenty of action in the next one. Also, I'm sure you guys have a lot of questions right now. Don't worry...all will be revealed later...

Anyways, I've kinda figured out an update schedule for this story. Every two weeks on Friday I will be uploading a new chapter. If there's any problems/changes to the schedule, I'll be posting those announcements on my profile.

So while you're waiting for the next chapter, feel free to drop a review. Especially if it has to do with constructive criticism. That'll be really helpful.

So, till next time!
