Chapter 4: Souls of determination.

The first few days in Beacon had proved to be interesting for Sans. Each human's soul contains different traits to resemble their owner. Sans was interested in every class they had to offer. Well, maybe except for professor Port's classes. That guy rambled more than actually teaching, which luckily, wasn't what he was studying at that moment. They were in miss Goodwitch class. Sans was watching the fight between Yang and Weiss and it was quite intense.

Yang was running at Weiss and continuously shooting her wrist mounted gun at Weiss, to which she summoned an ice wall to block the shot. Yang then shot her gauntlets down to push herself up in the air and then shot again to push herself torwards Weiss and threw a right hook. Weiss then slashed in an upward motion to deflect the attack and pushed Yang backward. After that, she summoned many glyphs to shoot ice spikes at her opponent. Yang then ran to her right and threw a lot of punches to break most of the ice spikes. Many ice spikes then hit her and lowered her aura.

Seeing that Yang was running torwards her, Weiss stopped the assault and created a glyph to launch herself upward and another to push herself away from Yang. The blond brawler didn't give up. She shot her gauntlets down to push herself torwards the heiress. Once Weiss was in the range of melee, Yang threw a left hook at the hieress. Weiss managed to deflect it but was hit by Yang's right hook and fell straight down to the ground and created a crater on the ground after landing on her back.

Yang didn't stop there. She shot her gauntlets to land her right boot on the heiress, to which she dodged and froze the ground. Yang slipped and hit her back to the floor. An ice block then hit Yang in the back. Without missing a beat, Weiss shot her Myrtenaster at the blond brawler. Yang blocked the shots with her Ember Celica. Her hair then burst into a bright yellow flame and her illiac eyes turned into a blood red color.

The brawler. Is. Pissed. She brought herself down to the arena like a bullet and destroyed the floor, causing Weiss to fell forward. Yang then jumped torwards her with incredible speed and threw quick, straight jabs at the heiress and sent her out of the arena.

Bzzzzt. The sound of the buzzer was then heard, signaling the end of a fight.

"YEAAAH! Now that's what I call a good fight!" Yang yelled.

"That can't be denied." Weiss replied.

"As you can see, Ms Schnee's aura bar has gone below the red zone. Which means, she is no longer capable of fighting. Thank you for volunteering to do the first battle. You two may return to your seat. Now, who wants to go next?" Miss Goodwitch asked. She looked around the room to find Pyrrah with her hand raised.

"Miss Nikos. Who do you want to be your opponent?" The professor asked.

"Sans, do you mind?" Pyrrah turned to a certain white haired boy who was resting his head on his left palm.

"huh? oh, sure. why not?" Sans answered, causing everyone to cringe, except team RWBY and team JNPR. They knew full well how powerfull Sans was and this was going to be an amazing fight between the two of the most powerful individuals while others just think that the Mistral champion was going to mop the floor with her opponent. How wrong were they.

Sans and Pyrrah then appeared at the arena with their battle outfit and got onto the once destroyed arena.

"Ready, begin!" Miss Goodwitch ordered.

Pyrrah raised her shield and got into a fighting stance while Sans just stand there with his hands in his pockets and his eyes closed. The unbeatable girl was cautious of Sans strange behavior. Either he was planning on something or he was overconfident. She didn't want to risk it so she transformed it into a rifle and shot at the jokester. Sans dodged the bullets with an incredible speed as she continued to shoot at him but to no avail. Sans was using 'kindness' to restore his stamina while dodging at the same time.

Seeing how bullets couldn't hit the blue hooded boy, she changed her tactics and charged at him. She used her spear to stabbed him but he was able to teleport a few meters behind her and summoned bones from the ground. The champion quickly jumped before the bones could hit her but she was then dragged to her right and met a bunch of more bones. Pyrrah raised her shield to block the bone from hitting her and was shot by some blasters from behind.

The champion then used her semblace to drag herself down onto the ground. But, before she landed, Sans pushed his left hand down and forced her onto the ground harder, creating a large crater on the ground. A shield was thrown at Sans with incredible speed but it just suddenly changed it's course and hit the ground to his left before it hit him.

Pyrrah then charged at the former skeleton with her rocket spear. Sans just teleported to the end of the arena and summoned dozens of blaster to shoot at her. Pyrrah raised her shield to block the heatwave and was slowly pushed back. The champion then jumped and kick the wall behind her to push her torward the blue hooded boy and prepared a strike.

Sans was planning on that and back flipped to dodge the jab. What then caught the Mistral champion's eyes was a storm of white and blue bones. She raised her shield to block them but was immediatly blasted by the blaster from before, draining her aura to the red zone. As soon as the sound of the buzzer was heard, Sans stopped the assault.

The crowd was flabbergastered by the battle. They couldn't believe that the unbeatable girl was defeated by a nobody, let alone not losing a single aura. There was a question in everyone's mind. 'Who is this guy?'

"Thank you for your performance. You both have done well. I hope you all continue your training. Class dismissed" Miss Goodwitch said.

"You were holding back." Pyrrah stated.

"dunno what you're talking about." Sans shrugged.

"You didn't use your strongest abilities like the ones in the initiation. I didn't see you using that dragon of yours." The champion told him, startling Sans. God, she was observative in combat.

"yeahhhh, ya got me there." Sans replied as he walked out of the ring. A blur of rose pedals then flew in front of him to block his way and yelled.

"That. Was. AWSOME! Can you teach me how to use those blasters? Pleaseee! I want to make one! Can we make one now?" Ruby was now an overexcited goofball once his weapons is used and Sans knew exactly why so he answered.

"ehh, sure, but after i have my lunch. i'm starving." The blue hooded boy said.

"YESSSSS! To the food court!" Ruby yelled enthusiastically. As soon as she left, Yang turned to him and asked.

"Did you just bought my sister's affection?"

"pfffffft! don't know whatcha talkin' about. hehehehe." Sans then walked in an opposite direction.

"Buddy, I'm watching – Wait, that's the wrong way!" Yang called him.

"i have a shortcut!" Sans yelled back.

TIMESKIP

Ruby finally reached the school canteen and noticed that Sans was already there. She was about to ask him how but stayed quiet after remembering what his semblance was. She quickly picked up her food and sat at a table and Sans did the same. Ruby couldn't help but feel weirded out by Sans choice of food. She hadn't seen him eaten anything other than spaghetti for the last few days.

"Sooo,... When are we going to start?" Ruby asked. Sans just sat down and dug into his spaghetti.

"ehhh, after this evening's class. i'm free then." Sans answered.

"Yeah, let's meet then!" Ruby said enthusiastically. People then walked into the room with them and started eating their lunch. Team RWBYS and team JNPR sat next to each other. Nora then talked about her imagine story and Ren kept correcting her while Sans doze off.

He then got dragged back into existance by the sound of a yelp. He opened his eyes to see team CRDL bullying a bunny faunus girl.

"Atrocious, I can't stand someone like him." Pyrrah stated. The group then turned their eyes to Sans, who was sitting on a table right next to Cardin's team.

"When the heck did he even get there? I mean, I know he can teleport but how did he do that without us noticing?" Nora asked.

"heya." Sans called to team CRDL.

"What the fuck do y – " Cardin cut himself off as soon as he saw who he was talking to. It was the boy who defeated the Mistral champion without any trouble. Becoming his enemy was not a wise decision, but his ego got the better of him.

"H-Hey, get lost! Don't you see that we are in a middle of something here!?" Cardin yelled at Sans, whose mask was covering his face and his hood was on.

"i don't appreciate you picking on somebody here. mind putting your hands off of her, pal?" Sans said with his calm, usual tone.

"Or what? What are you gonna do about it?" Lark challenged. This caused Sans eyes turned completely black and they so looked hollow as if he had no eyes at all.

"guess I asked the wrong question. well, here's the right one. do you wanna have a bad time? 'cause if you don't put your hands off of her right now, you are not going to like what happens next." Sans's burning aura could be sensed by everyone in the room. It felt so dangerous that it made Cardin unconciously let go of Velvet, causing her to fall backward.

"C-Come on guys, we have places to be." The brute stuttered as he and his crew quickly made there way out of the school canteen.

Sans's silver pupils then returned to his eyes as he pulled down his hood and mask, revealing his permanent grin on his face. He then stuck his left hand out to the bunny faunus in front of him. Seeing her hesitation, the blue hooded boy made a joke to calm her down.

"come on, it won't bite. or you just wanna sit Ear for a while."

"O-Oh, r-right. T-Thank you for s-standing up for me." The bunny faunus stuttered.

"heya, you are Velvet right? i'm sans. sans the summoner." Sans told her.

"H-Hi Sans, thanks again. But, h-how did you know – "

"your name? eh, Mustard heard it somewhere?" He lied. Sans checked her before coming to her aid.

*CHECK*

Velvet Scarletina

ATK ???

DF ???

A very shy person.

A faunus who uses her semblance to copy other's weapons.

She is thankful for your help.

She gave him a nervous smile before leaving. Sans smiled back before teleporting back to his seat and continued eating his spaghetti. Everyone's eyes were locked onto him. Noticing this, Sans gave them a playful "whaaat?" and everyone turned around and mind their business.

"It's great seeing a bully getting scared off like that. So, what didya do?" Yang asked. Sans just shrugged in response.

TIMESKIP

In the evening, Sans had taught Ruby everything she needed to make a working blaster before getting started on making one. Ruby learned everything incredibly fast so he let her do most of the work while he just lazing around. Seeing this, Ruby was not happy at all. She asked him to help her on making a blaster, not being his lazy self.

"Saaaaans! You promised to help me on this, not lazing around!" Ruby called to the blue hooded boy who had his back leaning against the wall and his eyes closed.

'Oh Oum, is sleeping his only hobby?' Ruby thought to herself.

"hey, lazy is such an ugly word. i'd rather use the term selective involvement." Sans joked, causing Ruby to pout.

"But you choose to help me!" Ruby yelled.

"okay, you got me there." Sans said as he stood up and walked torwards the blaster. He started making something with a machine but Ruby couldn't understand what it was. It looked like some sort of generator but she couldn't put a finger on it. She didn't wanted to know what it was but she had to make the blaster first.

"Hey, Sans? What are you making?" Ruby asked.

"it's an aura reactor. it helps transform your aura into a beam of plasma like mine." Sans said as he put it inside of the blaster.

He then backed off to look at Ruby's creation. It was a crimson blaster with the same design as his but instead of horns, it had rose-like pedals behind it.

"now, the moment of truth. Rubes, mind channling your aura into this thing? just don't stand in front of it while you do." Sans told the little girl.

Ruby then stood on the blaster like Sans did and it's eyes lit up in a red flame. It started floating once she stood on it. She then channeled her aura into her newly made weapon and it shot a large beam of red light into the dummy and burnt it to the ground.

Team JNPR was walking through the training room and Nora spilled her drink in excitement. She then ran up to Sans and asked him to make her one on her hammer. Sans simply shrugged as the girl got more and more excited.

'so Ruby is the soul of Determination. no wonder she and Frisk got along so well. heh, if she turned into something as remotely as bad as Frisk, i will be there to beat some sense into her. only this time, i won't be defeated. that's the least i can do for my mistake.' Sans thought to himself as he created a save file on the training room. Ruby saw that and asked.

"Sans? What are you doing? What is that light thingy?" Everyone (other than Sans) looked at her in confusion.

'so i was correct.' The former skeleton thought to himself.

"what do you happen to know about,... soul magic?" He asked.

"Uhhh, what? You mean aura?" Jaune asked. Seeing that this is not a good time to tell Ruby about her abilities, Sans decided to brush it off.

"nah, it's nothing. just don't touch it, alright Rubes?" Sans winked his left eye.

"But why? Why can't I touch it? Why can't people see it?" Ruby was a bit weirded out by Sans's behavior and abilities. It was,... Strange, to say the least.

"just don't. i will adress the Skeleton in the closet later." Sans said.

Ruby could have sworn that she saw Sans's eye sockets going hollow for a second as he said that. The blue hooded boy then teleported away, leaving behind a confused Ruby and an even more confused team JNPR.

Done! Finally a new chapter. Sorry for the lack of puns in this chapter. BTW, should I ship him with Ruby or Yang? Please, comment your answer in the comment section. It would help me a lot. Chara will show up in the next few chapter so be patient. I will be using narrator!Chara so don't expect an evil child demon.
