Long ago there were two races; Humans and Monsters.

One day the humans and monsters went to war. The humans won.

They sealed the monsters underground with a magic spell. Only those powerful enough could break the barrier.

And that's what the monsters focused on. They built a society, selecting the strongest monsters to be their leaders. The king and queen. The only monsters in the Underground with 5 digit stats.

And so a hierarchy was formed. The royal family having 5 digit stats, upper class with 4 digits and close to the royal family; aka the royal guard. Upper-middle class were monsters with 3 digit stats, usually with good jobs or training to be stronger. Then those with 2 digits are middle class. They are workers, but will take any opportunity to get stronger.

And then there are those with only 1 digit stats. At the bottom of the hierarchy, and viewed as too weak to become stronger, they are sent away to the home in the city. Where they wait until they are assigned a master to serve. At the very bottom of this big totem pole, is a short skeleton named Sans.

Welcome to UnderHierarchy. Where a monsters' stats are everything.

Smack! One of the many monster citizens backhanded Sans across the face. The force making the small skeleton fall over, a bruise now on his cheek. He grimaced for a moment as he focus on blocking out the pain. Then he looked up at his current master.

"You screwed it up again! You're so useless! That's it, I'm taking you back!" The monster yelled.

Sans was used to it by now. Something wrong happens and his master gets angry. When it happens too many times, he's taken back to the home of monsters unfortunate enough to be born with a single digit stat. Over in the city. He's probably the only one who's had so many masters before.

Of course he's had nice masters too. It wasn't always bad. But they usually were just working so much they needed help around the house, or something. So once they were comfortable, they didn't need him and would send him back.

So now here he was, in his dirty clothing, in his room in the home for servant monsters. That's the more politically correct term. They were really slaves to the stronger monsters. Sans didn't like this part, the waiting for a new master part. He just felt like he needed to be doing something. But with a building full of slave monsters, everything was neat, orderly, and how it should be. It was probably the cleanest place in the entire underground. So basically, there was nothing to do but wait.

But then one day, he was called down to the front office room. Seems like he might get a new master. He quietly opened the door, walked in and stood to the side. It was habit by now. But he couldn't help his surprise at seeing another skeleton. But he managed to stay composed. The much taller skeleton looked at Sans with a big grin.

"Hello Sans! I am the Great Papyrus! I realized lately that my training to be a royal guard takes up a lot of my time, along with patrolling. I don't have a lot of time to keep up with things like the house. I am in need of assistance. Of course being the Great Papyrus, I could do everything I need to. But then I would have less energy for training, and then I wouldn't be doing my best! So I came here." Papyrus said with the cheeriest voice.

Sans bowed his head slightly. "I am honored to meet you sir." Sans said with a quiet but clear voice.
"Mr. Papyrus here got very excited to hear we had a skeleton available to be assigned." The monster that runs the home said.

"Oh yes! I don't see a lot of skeletons around. It's so nice to meet another!" Papyrus said still very cheerful. Sans simply nodded in response.

"Well, everything is in order. All the paperwork is filled out. Remember, you can return him anytime you want." The other monster in the room said.

"I'm sure everything will be great! Let's go Sans!" Papyrus responded. He thanked the monster and then the two skeletons began their walk back to Snowdin.

Papyrus took up most of the talking during the walk. Sans was mostly to his thoughts. Why did such a monster like this skeleton want him? Certainly he was told of how he's the most returned servant and the one with the most complaints. Why would he still want him? What was his stats anyways? It must be high if he's training to be a royal guard.

While Papyrus chatted about Snowdin and his royal guard duties, Sans checked him. Five hundred fifty!? He has a stat of 550!? Sans accidentally let out a squeak of surprise. Papyrus stopped as he felt himself get checked. He turned to Sans, who immediately stopped and stiffened.

"Did you just check me?" Papyrus asked. Sans bowed his head and immediately began apologizing.

"I-I'm so sorry Master! I'm sorry! I-I..." Sans said. He shook just a little bit but tried to keep his body still. Papyrus let out an innocent laugh. Which confused Sans.
"Nyeh heh heh! I figured you would do that eventually. I get checked all the time when I meet someone new! I don't get why monsters don't believe me when I tell them my stat. But it's fine! And you don't have to call me "master". Just Papyrus is fine. I mean, I don't own you." Papyrus said.

Something in Sans' soul swelled. This skeleton was just so... pure and happy. Sans felt something but he couldn't place what it was. But for the first time in a while, his smile was genuine.

He nodded to Papyrus. "O-Of course ma-... P-Papyrus. Master Papyrus." He flinched as finished talking. He just couldn't bring himself to call his new master only by his name. But Papyrus smiled at him instead of getting angry.

"It's ok, we'll work on that. Now welcome home! This is my house!" Papyrus said as he gestured to the two story house, all decorated. Sans didn't even realize they continued walking.

So the house next to the library is Papyrus's home. Sans is often in Snowdin for jobs, but he has never seen Papyrus around here before. Maybe he was the one that set up all of those puzzles around here? Sans snapped himself out of his thoughts. Papyrus walked up to the door and unlocked it. Sans followed him inside. The inside of the house was nice and cozy looking. Sans liked it.

"I always had a second room that I didn't know what to do with. So it can be your room now! We'll personalize it over time. But right now it does have a bed, drawers, and a lamp!" Papyrus beamed as he pointed out a blank door to the right. The one to the left obviously being his own.

Then the excited skeleton looked Sans over, his eyes narrowed. He held his chin with a "hmm" in thought. Sans began to get nervous, small beads of sweat forming on his skull.

"Are you sure you're going to be warm in that? This is Snowdin after all. I think I have some old clothes that may fit you." Papyrus then said with a smile. Sans was relieved he wasn't in trouble.

"Thank you Master. I m-mean, Papyrus. I'm fine with what I h-have on though. Y-You don't have to. B-B-But! You can do whatever you want! O-Of course." Sans responded. He got a bit nervous Papyrus would be mad at him for refusing a gift. But Papyrus smiled instead.

"If you're warm in only a white tank top and blue shorts, then ok! But I still want to give you something warm and also shoes to wear if you do ever get cold." Pap said. "I'm sure I'll find something for you. You are rather small though. I bet I could carry you around in my arms like a child! Nyeh heh heh!" He continued, laughing at his silly idea. Sans blushed slightly from embarrassment and couldn't stop himself from looking away.

"Oh! I'm sorry Sans! That was rude of me for poking fun at your height. I shouldn't have said that about a new friend." Papyrus then said with a regretful look.

"No! I-Its ok really. You can s-say anything you want to. You c-can say I have... th-thick skin?" Sans reassured his master. For some reason, he felt sad seeing Papyrus's smile go away. Which is why he made a joke. Jokes make monsters laugh so, maybe it would make him smile again? Although he wasn't that funny and only knows bad puns, which that was one. But it always made him feel better. So he gave Papyrus a grin but it was a nervous one.

"Nyeh! That was a pun, wasn't it? Oh I hate those awful puns! They're so tasteless!" Papyrus exclaimed, a bit of a groan in his voice. Sans seem to shrink even further down to the floor. He winced, now he was gonna get it.

"I'm sorry Master! I'm so sorry! I w-won't do it ag-gain!" Sans pleaded. His voice shook a bit. He didn't want to mess things up already! Papyrus seemed really nice and he really wanted it to stay that way.

"No! No, it's ok! Please don't be sad. Puns are just not the kind of humor I like. It's ok if you like them though! Hey, with all this excitement, why don't we have something to eat? I've been taking cooking lessons! And I'm getting really good at making spaghetti! I'll make some for us!" Papyrus said, trying to comfort Sans. He gave a comforting smile to the small skeleton. Sans seemed to feel better at his words. So Papyrus lead Sans to the kitchen.

"Alright! I'll get out the healthy ingredients!" Papyrus declared. But as he reached to gather them up, Sans quickly got them for him. "Oh. Thank you Sans! You didn't have to." Papyrus said with a smile. The same happened with the spaghetti box. And then while Papyrus was stirring the pasta, Sans tried to reach to the upper cabinets to get the plates. But it wasn't exactly Sans height.

Papyrus looked over at Sans standing on his tippy toes and reaching as far as he can. Sans's left arm reached up to the cabinet while the other had a grip on the counter below. Papyrus couldn't help but smile. Then he walked over to Sans and lifted him up. Sans eep'd in surprise by the sudden feeling of being lifted. He looked over to see the smiling Papyrus.

"You looked like you needed help there. Here you go!" Papyrus said cheerfully. Sans couldn't stop the blush from spreading across his face. Because of the strong but gentle grip on his pelvis bone, and cause of Papyrus's face. It was so nice and... cute?

Sans quickly looked towards the cabinet in front of him and opened it. He grabbed two plates and closed the cabinet door. Papyrus gently put him back down.

"Th-Thank you Master- uh Papyrus." Sans said. He forced himself to look at Papyrus, which didn't help his blush and how embarrassed he felt. His master was just... smiling at him happily.

"Oh you're welcome! The Great Papyrus is always willing to help!" Papyrus said with a grin.

The spaghetti wasn't very well made. But it was made by his master, so Sans ate everything that was on his plate. He couldn't refuse his master. Although he was at a loss of words when Papyrus asked if he wanted more. But thankfully Sans realized what time it was at that moment.

Sans quickly stood up, the chair moving back a bit. "Ah! I-I'm sorry Master! I have to g-go now. I have a job I need t-to get to. I'm so sorry!" Sans exclaimed, although his voice was still soft.

"Oh. Well go then! You don't want to be late. I'll clean up and then make sure your room is all ready." Papyrus replied with a smile. Sans would of told him that he could clean up himself. But his master was right, he didn't want to be late.

So Sans quickly thanked his master and then ran out the door. Then as quickly as his bony legs could carry him, he ran to Grillby's. He quickly ran inside, made sure he didn't run into anyone, and up to the bar counter. He huffed a bit as he spoke, trying to catch his breath.

"I... I'm here Grillby. I... I'm sorry. I got-" Sans said but stopped when Grillby put his hand up.

"You got a new master. I understand Sans. It's fine. You're not that late actually." Grillby said with a calm voice. A small smile was on his face. Sans was glad and thankful Grillby was so nice. To Sans, Grillby was his best friend.

Sans gave a small smile back. Then he went around the counter and pinned on his "Grillby's" pin. "So. Who's your new master? If I may ask." Grillby asked Sans while cleaning a cup.

"Of course I don't mind. You can ask whatever you wish. His name is Papyrus." Sans responded as he began working.

"Oh yes, I know him. I met him once. He doesn't come here often though. He "doesn't eat grease" as he put it." Grillby said. Sans nodded to show he heard Grillby and understood. Then he got to work waiting on monsters, cleaning up, and other things.

When Sans got to the house it was late and the entire place was quiet. Papyrus must be in his bed already. He looked in the kitchen to make sure, and indeed it was clean and his master was not there. So Sans then went up the stairs to his new room. And as his master said, there wasn't much in it. But Sans was used to that.

Sans looked around the room while walking over to the bed. He had to admit, it was strangely homey in here. He actually really liked it. Sans then noticed the bright blue jacket and bright white fuzzy slippers on the bed. He walked over to it and picked up a sticky note that was attached. It read; I found a couple things that I think could fit you. Blue isn't really my color, so you may keep it! If you get cold, please wear them. They're fuzzy so they must be warm! -Papyrus

Sans smiled. He really did feel something when it came to this new master. He felt strangely safer with him around. He then put down the sticky note and picked up the jacket. He felt the fabric in between his phalanges. It did feel soft and warm.

Sans put on the jacket and slippers, then layed on top of the bed. He had a habit of not sleeping under the covers. As he waited for sleep to overtake him, he thought. This was the first day with a new master. And honestly he thinks he's actually happy about it.
