// Authors Note: Ah, yes, guess who is posting twice in one day? I am. I am here with the game plan for chapter number two. Hopefully, it will go as smooth as the first chapter had. Comments, opinions, and suggestions for ships are always going to be appreciated. I am not much of a flat out romance writer, but I wanna try my hand at a ship this time. Until next time, and have fun, peoples. //

If there was anything that Sans was not completely fond of, it was movement. There was always something about work, and generalized 'Activity' that she could not bring herself to appreciate. Maybe it was because she was simply lazy, or perhaps it was some deep resonating reason she had yet to even figure out within herself. 

Whichever way the pizza was sliced, it did not make this situation any more amusing than she had already seen it as.

Yes, 'Amusing'. 

Was that what she really wanted to call it? 

She wanted to be a hero, to keep people safe, but she was still very, very lazy. There was no need to hide it, it was plainly obvious to most who saw her. A slouched posture, lazy attitude, and barely notable motive. In a pro-heroes eyes, she might come off as incompetent, because of appearing so nonchalant.

"Alright, first, we are going to be doing the ball-throwing test. I will be assessing your scores from Junior High, and calculating how much you improved between that time, and now." The dark haired man mentioned to his students loosely, before he adjusting a digital calculator in his hands. "Sandra, you may come up here first." 

Sans pulls her hands up behind her head, the back side of her hair was tied in a lose pony-tale on the base of her head; messy, of course, as long as it was all in one general area. "A'ight teach."

Walking up to the man, she grabbed the ball with her hand, before looking at it. She thought back to when her, her brother, and the kid had to deal with one of his traps set up for humans. Frisk balanced the ball so easily on their head, it seemed unnatural. She smiled at the bitter-sweet memory, before walking to the line provided by the course instructor. 

"Sandra Gaster, last record was 67.9 meters. You may proceed." Aizawa leans back, watching the white-haired girl with a calculative look of indecisive boredom. Something common for him to be seen with. Looking back at his other students, he took note on how tense they were, most likely due to the threat of being expelled if they got the lowest grade.

Good. If they are going to be in this school, they better be trying their hardest. If they were not to try their hardest on an assignment, there would be no proof of their dedication, and efforts to be here in the first place. 

The way he saw it was 'Try your hardest at ALL times, or don't try at all. Don't waste your own time, and and someone else's'

Watching the girl he had handed the ball too, he easily took note of her lazy demeanor and tired eyes. Her slumped posture and sleeping habits in the classroom and before the entrance exam a few short days ago. Sleeping standing up was quite a feat. Something that would not do anyone any good, sadly.

He sighed to himself with all of these thoughts in mind.

Aizawa had never liked punishing children, or making them feel bad. He was just blunt. If someone was not cut out for a task, he could almost always tell right away. This girl though, for as short of a time as he had, was hard to read. 

Her fighting footage, and skills were so simple, and she seemed to know a lot of what to do with it as a whole. She easily took down the robots she had come to face. She barely even had to move.

Most of the other students had to get up close and personal in order to not interfere with each other, or themselves. Midoriya, Bakugou, and Iida were all decent examples of that. Midoriya needed to make physical contact with his opponents. Bakugo had to be at a close enough range to not cause drastic damages with his explosions, and Iida, depending on what he used, also had to make physical contact with opponents. 

With an even more concentrated glance at Sans, he watched as she got ready to throw the ball. 'I wonder just what she can do...'

Summoning up all her strength, Sans closed her eyes and takes a deep lean back as she wound her arm in the same direction. Thinking about her reasons to want to be a hero; as well as keeping her brother and friends in mind, she opens her eyes and takes the throw.

Leaning forward quickly, and putting all her backbone and magic into the throw. Her soul-grasping magic came out of her palm as a pulse of cold air produced by her momentum. Her eye was left ablaze, blue ghost fire coming from it for a couple seconds more, before it slowly vanished back into oblivion of its origin.

The ball flies into the sky above the training field, spinning at a rapid rate, before eventually falling back to the ground. 

"1243.5 meters. Next."

Sans nodded to her teacher before taking her leave, walking back over to the group of classmates that stood there shocked, impressed, or generally uninterested.

"Whoaa, sick score man!" A boy with red up-styled hair grinned. He appeared semi-sharklike, with sharpened teeth and a scar over his eye. However, despite this, he seemed to have the personality of a friendly guard dog. He was definitely competent, but that did not make him any less welcoming. "I am Eijiro Kirishima, nice to meet you!"

Sans went to shake the others hand, chuckling at his extroverted, happy nature. However, the second she shook hands with him, there was a loud, wet-sounding 'Pppphhlt' that sounded right afterward. Everyone looked at them in surprise, or borderline disgust before seeing what the cause of the source of the noise actually was. 

There, on her hand, was a whoopee cushion. The girl smiled cheekily, and lazily laughed at the other who was a flustered in confusion. However, soon after, he started to laugh as well. 

"Sans. Nice to meet ya." She greets the other, closing her eyes a bit before leaning back and watching as the brown-haired girl that had been talking to 'Izuku' the day before walked up to the teacher, and received the throwing ball everyone else thus-far had. 

The brown-haired girl was later referred to as 'Uraraka' by the teacher, so Sans assumed that it was her last name. Most of these people in this world called each other by their last names, most likely as a form of respect or courtesy. She ended up getting the best score, with the numbers reading 'Infinity'.

Impressive.

After several other students introduced themselves to her, most in interest of her 'quirk' or just her seemingly strange personality, the classes went on. Including a long jump, running exercises, and other small events to try and calculate speed, strength, or even smarts. 

The day was still as slow as it had started. However, with people to talk to, she found it a bit more bearable. Mine kept touching her hair, seeming to have an obsession with braiding it. Mina seemed to be the real social butterfly of the group. Not afraid or second-guessing starting a conversation with anyone. 

Kirishima enjoyed watching the others compete, and show off their quirks during them exams. It was fun to see just how much potential someone else had. He called quite a bit of other stuff 'manly'. Sans was sure that his version of manly really meant 'cool, or really outstanding. Maybe even morally 'just' ' rather than just viewing it as something a 'man would do.'

Denki seemed to find Sans looks very appealing, but he did mind her space when he got close. He outright called her hot though, which earned a smack in the back of the head from another classmate of theirs. Her name was 'Jirou' from what Sans remembered.

After some time, Sans found herself asleep. Sans was sleeping standing up again, something her classmates had yet gotten used to. She snored lightly, standing still, and content in one place. She was done with testing for her final class for that day, so there was no real need to fret. 

Bakugo, in his infinite condescending manner, and went to sweep his feet under Sans' legs in an attempt to get the girl to fall on her ass. However, in return, Sans only ended vanishing in a flash of light blue, appearing behind the blonde just in time to knock him down to the floor. She laughs at him, more or less in the form of a light chuckle, before offering to help him up. 

He simply grit his teeth, and made a low 'tch' before shooing her arm away. He was obviously steamed from easily being caught off guard. He stomps away, grumbling and complaining to himself ahead of the rest of the class. 

"Moody." Sans mumbled to herself, chucking lowly. After Bakugo had made it a bit away, several of her classmates go over to her, wondering what it was she just did. 

"Whoa, you have strength AND can teleport? So cool!" Mina cheered from the side, clasping her hands together. 

Heh, if only they knew the half of it. Sans nearly forgot that most of these other classmates of hers hadn't even seen her other laced in abilities yet. For the most part, they were all distracted during the exam, which means they would not have noticed her other powers. 

All in all, they had only bore witness to 'levitation-like' abilities and now teleportation. No big deal. 

From what she had seen, most students only had one 'quirk' in this world. They only had ONE power. Seeing her with TWO vastly different things that could not be explained as an evolved quirk must have been rare. The other closest person to what she had might have been the red and white haired kid. She forgot his name. 

He had fire and ice powers. Most could argue that, with them both being elements, it was just a graduated version of his quirk, whichever way it may have started off. 

Midoriya was off with the brown-haired girl, though he was mumbling to himself after seeing what he had just seen. His mumbling was sort of freaking some of the other students out, if not simply making them confused, or half-way uncomfortable. 

Sans chuckled. It was kind of amusing, after all. He seemed like a try-hard, though that was not her trying to be mean about it. She was sure he tried his best to even be able to get into this school. Him hurting his arm the way he did, though, made her suspicious of his quirk. It was as if his body was not used to it. 

Even with her limited amount of time in this world being 4 years, she knew that these people grew up with quirks. While most people had not mastered them, by any means, they sure didn't have such bad, or painful looking drawbacks as he had. 

'Maybe I am just overthinking it. I don't know what goes on in this world. I am still a stranger to it, despite being here as long as I have. In my world, humans didn't even really have powers. They bartered for them, or ended up with them via malevolent forces of some kind. Voluntarily or Involuntarily. 

After class was adjourned for the day, everyone went to their respective locker rooms. Sans, being in the female locker room, tried to clean herself up as quickly as she could, and get dressed away from everyone else. She may have been a girl for 4 years, mind you, not that he tried, but she still wanted to respect other people's privacy. 

Getting dressed in a stall, she brought up a comb, and started to comb out her hair after a nice long shower. Her hair was soft again, and smelled like strawberries and orchids. It was always a nice feeling, no matter what gender you were. 

As soon as she walked out of the stall, though, clothed in a sports bra and high-waistband shorts, she heard a scream from the guys locker room. 

"Hm?" she looks over to a few benches that lie in the corner of the locker room, several of the other girls wrapping their arms around themselves in a semi-protective manner. Jiro had one of those earphone-jacks stabbed through the wall, and it had hit someone else in the eye from what Sans had heard. However, she looked away, seeing as most of the other girls in the room were only in a basic bra and undergarments. In a way, he felt he was disrespecting their privacy. 

'Just what have I gotten myself into?'
