Sans jolted awake. It was maybe two, two and a half months since he was taken to this world. He didn't believe he'd been there that long, but the tally mark and the calendar Mrs. Ichika was kind enough to give him said otherwise. He missed his brother. He missed his father. He missed his friends. He missed Grillby.

Regardless of all that, he would be forever grateful to the Kirishima family for letting him stay in their home. Grateful for them giving him enough food to have a full stomach. Grateful to Eijirou for sharing his room. The Kirishima household wasn't extravagant, despite Mrs. Ichika's massive income. It was a small two story house with two bedrooms, a lab, and a bathroom on the top floor, a kitchen/dining room, living room/lounge, and a bathroom on the ground floor, a basement/laundry room, and an attic/storage space.

Their house was small, but it was one of the warmest homes Sans had ever been in. He didn't want a bed. He slept in a sleeping bag with a couple of blankets on the floor next to Eijirou's bed. He didn't plan to intrude for very long, so there was no need to have a bed.

Sans woke up because of a nightmare. He kept seeing Papyrus pulling at his scarf to try and pull him back to the ground. Only to wake up when he was sucked through the vortex.

Eijirou - "Sans? Are you okay?"

Sans - "I'm fine."

Eijirou - "Was it that dream again?"

Sans - "Dreams are good. Nightmares are bad. Night-terrors are...something else."

Eijirou - "Did you have that nightmare again?"

Sans - "Yeah. Sorry for waking you up."

Eijirou - "You didn't. I was on my phone."

In the short time Sans knew Eijirou, he knew how bad a liar he was. The sleep was clear in his voice and his eyes were lidded.

Sans - "You have to be up soon for school anyway. Let's go make breakfast for your moms."

Eijirou - "Okay. I'll get in the shower and get dressed."

Sans - "Use the downstairs bathroom. We don't want to wake your moms."

Eijirou - "Okay."

Sans got Eijirou's uniform ready and sent the still sleep ridden Eijirou downstairs. He didn't know any Japanese recipes, but he had some of Grillby's memorized. So he made green chili and cheddar omelets, choco-milk, strong coffee, and sausage stars...Grillby would cut his water sausages into stars, his toast into flowers, and his fruit like planets. He missed Grillby.

Natsumi - "Damn it smells good in here."

Ichika - "Nats, language."

Sans - "Morning ladies. I made food."

Ichika - "Screw food, gimme that coffee."

Natsumi snickered and gave her exhausted wife a cup with no sugar and no milk.

Natsumi - "There you go my beautiful wife. Black, just like your soul."

Sans - "Her soul ain't black. It's dark green."

Sans drank his extra chocolate choco-milk and pulled Ichika's soul from her chest. Like he said, Ichika's soul was dark green and very bright.

Sans - "See? Kindness. I would hate to find anyone with a black soul."

Natsumi - "What's my soul look like?"

Sans - "Yellow. Justice."

Sans pulled Natsumi's soul and resumed eating his food.

Ichika - "Now that I'm at least semi-caffeinated, Sans. I'm sending you to Junior High with Eijirou."

Sans choked on his omelet. Natsumi panicked a bit and slapped his back a few times.

Sans - "What?!"

Ichika - "Junior High. You. Going. Today. I already enrolled you, your uniform is in the upstairs bathroom, your registered quirk is Shortcut, and your name is Sans W. Gaster. Your new history in this world is that you transferred from Alaska, U.S from a little known town. Get it, got it, good. After you're done eating, go get in the shower."

Sans couldn't get a word in and Ichika's face and tone left no room for argument.

Ichika - "This is the best way for you to pass the time and continue learning. I'm working hard to send you home, but the process is a slow one with only myself on the project and with very little leads. So don't bother fighting me on this."

Sans stayed quiet and finished his food. Never before had he dreaded going to his lessons. He was most likely smarter than every kid in that school put together. He didn't want to get attached to more people that he'd have to leave behind.

Sans ate the rest of his food and quietly stalked upstairs to the bathroom. One scalding shower later, Sans was basically swimming in the smallest size of the Mustafa Private Middle School uniform. As soon as Sans walked into the kitchen holding the pants up so he didn't trip, Natsumi and Eijirou were is hysterics. His face burned a violent shade of blue as he stood on top of a chair so Ichika could sew his pant legs and sleeves shorter.

Soon Sans was rifling through his new book bag filled with standard first day of school stuff. He also had one of Eijirou's old Red Riot lunch boxes packed with karaage, rice balls, and money to get more food at school.

Soon, Sans was walking with Eijirou to school. Eijirou carried both of their bags and Sans's lunchbox. Sans was sulking the whole way to school. He still wasn't happy with Ichika forcing him to go. Even more so with limiting his magic to his shortcuts. No Blue Magic, no Gaster Blasters, and no Soul Manipulation.

Down the sidewalk, Sans watched more students leave their houses and walk to school. Sans could pick out the kids with minor sins and deduce them as bullies. He expertly weaved Eijirou through the crowd to avoid the bullies. It didn't take long to get to the school and it took even less time for people to stare at the "new kid." Sans stuck close to Eijirou to prevent confrontation.

Eijirou took Sans to the school office to pick up his school ID and to give custom measurements for a new set of uniforms. After that Sans got his school schedule and a map.

Eijirou - "We have second, fifth, and last classes together. Luckily our first classes are right across from each other. It looks like Ma signed you up for Creative Writing, Japanese History, AP Math, Chemistry, Psychology, Social Studies, and physical education."

Sans - "I don't have high expectations. I was one of three lead scientists in the Underground. The only one I think will be somewhat interesting is Japanese History for obvious reasons."

Eijirou nervously laughed as he led Sans down the hall. Eijirou's first class, art, was indeed across from Sans's first class, Creative Writing.

Eijirou - "See you in half an hour."

Sans - "Fine, see you then."

Sans slunk into his first class and sank into the closest empty seat he could find. He let out a big yawn and laid his head on the desk.

"You're in my seat."

Sans lifted his head slightly to look at, who he assumed to be a mutated shark monster. He and this other monster were the only two in the classroom so every desk was empty, but this guy was insistent that Sans move to another desk.

Sans - "Look, pal. There are plenty of open desks. Your name isn't on this one."

The monster gave a nasty grin as more students started making their way into the classroom.

"I don't think you know who I am."

Sans - "What gave it away? That I'm the new guy?"

The shark monster's face went from gray to an unflattering shade of purple. He then smirked and grabbed Sans's shirt collar. He pulled Sans's smaller body to him until their faces were uncomfortably close and where Sans's feet hovered a good two feet off the ground. Sans's lazy grin grew sharp. The shark monster's eye twitched. Sans activated his magic enough to get his left eyelight to glow blue and his right to vanish. He slowly brought his hand to grip the now shaking arm holding him up.

Sans - "I don't care who you are, pal. If you don't put me down, you're gonna have a bad time."

Sans was dropped into his chair right as the tear walked in.

Teacher (Female) - "Saichi Kei, why are you so pale? Head on down to the nurse office. Gaster, come on up to the front and introduce yourself."

Sans was baffled at a human with a tree growing from her head. He reluctantly trudged up to the front and faced his new awestruck peers.

Sans - "I'm Sans, Sans th-...Sans W. Gaster."

He was stopped from sitting back down when people started asking him questions.

"What's your quirk?"

Sans - "My quirk is called Shortcut."

"Are you a foreigner?"

Sans - "Yes."

Sans ignored the rest of the questions with an annoyed scowl and sat back down. The rest of the class period was spent reading old horror stories from different cultures for some upcoming writing project. Sans was quick to leave the room and met up with Eijirou right outside the door. Eijirou was in the process of putting his blazer back on. Sans could see a bunch of little paper cuts and slightly bigger cuts on his arms.

Eijirou - "Hey Sans, how'd you like CW?"

Sans - "What happened to your arms?"

Eijirou - "Hm? Oh that...Don't worry I'm fine. Come on, we're gonna be late to history."

Sans followed Eijirou to the history classroom and nothing. He woke back up when the bell rang for the third class.

Sans - "Did I sleep through that class?"

Eijirou - "Yeah, but you didn't miss anything. Mr. Nakamura is absent so it was a free period."

That's basically how the day went until lunchtime. Sans would go to class, put the fear of the Royal Judge into some bullies, introduce himself and meet with Eijirou outside the classroom with more bruises on his body, rinse and repeat. Then lunch came around and Eijirou was quick to usher Sans outside to a big tree with tables around it.

Sans thoroughly enjoyed the packed lunch from Ichika. Eijrou's lunch was unceremoniously booted to the ground and stomped on by Saichi Kei and his school-aged goons. Where was Sans? Sans was using the money Ichika gave him for more food. Sans grabbed Saichi's soul (purple, perseverance) and pulled him so close to him that their noses were nearly touching.

The gray leathery skin on Saichi's face went incredibly pale. The other three students left Eijirou alone and changed to Sans. Sans trapped each of them in a cage of bones. His eyelight started flashing from yellow and blue repeatedly.

Sans - "what do you think you're doing to my little brother? i said it earlier, i don't care who you are. Stay the hell away from kirishima eijirou or else. do you understand me, shark?"

Fervent nodding earn Saichi his and his goons freedom. They all ran off and Sans sat next to Eijirou.

Sans - "Here ya go. Eat up."

Sans placed the tray in front of Eijirou. Rice, a bowl of miso soup, a side of orange slices and grapes, and two hamburg steaks with a chocolate yogurt drink.

Eijirou - "Thank you."

Eijirou knew Sans would let him decline the food, so he accepted it graciously and ate the school lunch with a hunger he didn't know he had. Sans kept his eyes trained on the immediate area around them to ward off anymore bullies.

<~<~>~>

Sans - "Finally!"

Eijirou - "How'd you like your first day of school Sans?"

Sans - "Better than I expected. It'll take a few weeks before the bullies learn not to mess with you though. Be right back, I left something in my locker."

Sans took a shortcut to his assigned locker and retrieved his copy of the house key and his history book. Upon getting back to Eijirou, he was smiling brightly and talking animatedly to a girl with bright pink skin, dull pink hair, black eyes with amber colored irises, and wearing the school uniform.

Eijirou had a massive bruise on his cheek and the girl had similar black and blues on her arms and legs but they were both happy and unbothered.

Eijirou - "Sans!"

Sans walked over with his easy going grin.

Ashido - "How ya doing! I'm Ashido Mina! Kiri's new best friend!"

Sans - "Sans Gaster, I'm Eiji's brother."

Mina walked with them back to their house then jogged down the road to where she supposedly lived.

Ichika - "Welcome home boys. Eijirou go wash up. Sans, how was your first day?"

Sans - "You were right. I learned a few things and passed the time."

Ichika - "Told you so. How does seafood hot pot sound for dinner?"

Sorry for the long hiatus, I was annoying the crap out of Pegasus_3504 since she finally came home. So sorry not sorry. This chapter is one part filler, one part a request, and one part backstory (which I love to write, and another one is gonna be made. Guess who it's for)

This great chapter is dedicated to IGiveOutBadKarma. They requested in the last QnA to know how Sans and Mina met and I was given the perfect reason (read excuse) to write another backstory chapter! So kudos to them! Hope you liked the chapter!
