Chapter 1

// Story Warning: This story is NOT an original idea! This story is INSPIRED by, but will NOT be a carbon copy of this fanfiction right here >> Sans the hero [BNHA x FemaleHuman!Sans] [crossover] . This story, sadly, has not been updated in about 9 months. So, I am taking inspiration from it, and making my own spin-off based off of it. Once again, the original idea is not mine. If the creator is still around, feel free to go and give them kudos for their amazing work. My beginning chapter is going to be loosely based on their first chapter, but I am going to be mixing it up a lot. Further along in the story though, I promise that it will be vastly different, if it is not vastly different in this chapter already.//

For Sans, or 'Sandra' for a formal name, the robots were an easy task, despite her laziness and basic nonchalant attitude toward most of the stuff around her. It was not as if she did not care about what was going on, she just didn't really mind most of it. All of it was common, or felt like it had happened once-upon-a-reset. At least once before, no matter how it had been executed. 

She had been transported from her own universe, after the player had done something awry... and her friends, her family, were all left behind. Her soul still hurt. Her home, and everyone she knew was gone. EVERYTHING was gone. 

To her, it felt as if that life she had lived, all the lives she had lived, had turned into a failure. Her friends were not coming back, the kid was not coming back, nor was Chara. 

The only relief was that the PLAYER was not there. There were no PLAYERS. Everything was just... normal. Is this even what 'normal' would be? People running around with superpowers? Shockingly enough, she could still grab peoples 'Souls', it just manifested in a different way than souls in her original home had. 

Her being a girl was also something that was very, very new. However, she also was not going to complain. For a human-ish female, Sans didn't look half bad. She was of a short, but still fair height. Her skin was as pale as bleached ashes, and nails rested permanently painted a jet black color. Her hair was soft, and white, with a light blue blush visible in it, if one looked hard enough for it. Her overall build was fit, though she could argue that parts of her will still plump. This however, just made her figure look more 'full' than chubby. 

Her eyes whites were also a deep black, white iris's and a light gray pupil made up where her 'pinpricks' would have been. Sans had a small button-like nose, and almost-always tired expression scribbled all over her face. The light bags under her eyes were the main implication of this though.

She had now been in this world for 4 or so years. She missed everyone so much, and still constantly suffered from night terrors. The only thing she has on her anymore from her own world was Papyrus's scarf, Asgore's Staff, one of Toriel's favorite porcelain plates, a frozen-in-time spear of Undyne's, Alphys's Glasses, and several other peoples favorite objects. 

Having stuff that her friends had actually loved was the only real thing keeping her sane. The only thing she would ever SOMEWHAT thank the entity for that had done this to her. That had taken her away from her home, and the continual resets.

She had been taken from the bane of her existence, and the pain of her life. However, in the process, she had lost the reasons she lived, and the only ones who ever made her feel valid in her universe. Victory, or what it might have been called, has been so utterly bittersweet and cruel to her. It needn't matter which way she had turned. 

Either way, that did not change the life she chose. This new life of hers was somewhat a second chance. She could be as she was, and still do her best to save others. She could become a hero. She could protect new lives, and save those who do not have the ability to try over. For those who would perish forever, with no certainty of a second chance. A third, fourth... thousandth chance. 

Dammit... there she goes again.... trying to blend her own old reality into her new one. 

Trying to merge her lives together as if it were some odd kind of puzzle. 

She can't afford to think about that right now.. she has to ace this test. She needed to get into this school. She could not be a hero without going through this school. She would rather not be seen as a vigilante. That would only put a large target on her head. One that she could avoid having to go through at all. 

"It's a beautiful day outside... birds are singing, flowers are blooming. On days like these, tests like this... really fucking suck."

The opening exams of Yuuei High School were no easy task to complete. They were meant to be challenging, and thought-evoking. Hero-Monitored, Hero-Oriented. These exams were put in place to ensure that students that had gotten accepted by the school would be competent enough to even deal with such a task. 

After all, if one could not deal with a simple robot, how could one deal with ACTUAL villains? 

After the test was over, the results were shown for the amount of points that had come in. Sans had come within the first five places on the Leader Board for combat points and a few Rescue Points. 

Sans was unsure if she should thank, or be annoyed with the person that had caused her to have to do anything for Rescue Points to begin with. Another competitor in the exam, one with spiked hair, and deep red eyes, had been going crazy out there in the fighting field. Using his 'quirk' as they were called, to blow up robots.

Blowing up machinery is never a good idea, of course, but it was blatantly obvious that whoever this kid was, did not care. 

'Katsuki Bakugo', that was his name. Sans sighs to herself, before looking to the side. This 'Bakugo' kid was practically a messy mixture of Undyne's hyperactive-destructiveness, Mattaton's narcissism, and the PLAYERs malicious intent. 

Looking over in some other direction, Sans had found a source of all of the outward commotion that had caused disruption on this testing field. 

A boy she had seen on her way into the testing grounds lay sprawled out in on the middle of the ground. His arm was reddened and swollen, blisters forming over quite a bit of the limb. More than likely it was something that had to do with 'Quirk Drawbacks' or whatever everyone else was so content with calling it. 

Nevertheless, it looked painful. 

A small woman, just a bit over half the height of the students in height, walks over to him. Grayed hair forming a bun over her head, and medical equipment in tow. After making sure there were no other serious damages, the woman gives the green-haired lad a medical gummy. The wound was healing up in no time at all.

After some time at her lonely home, Sans had finally received a letter in the mail from the Yuuei. Which, all in all, was more of a relief than it was great news. If she would have failed the beginning exam, she would have been somewhat devastated. Even though there always would have been next year. 

Judging by the scores she had seen on the video clip, she had done some impressive work. The number one hero, All Might stands in the clip, dressed in a lemon yellow suit with a broad smile over his muscular face. It somewhat reminded her of her brother, who's smile was always bright and genuine. 

After the clip had ended, Sans felt her eyes well up with tears. Looking down to the scarf she had kept around her neck, she wipes at her eyes, before bringing her knees to her chest. "I miss you Paps... I really wish I could be as cool as you were...." 

Upon walking into class the next day, she took note of everyone she was going to be working with during this time here at this high school. 

The same blonde hothead from the day before was there. She could just feel them bashing heads together quite often. Most likely because she will end up doing something to piss him off. Another one of the more notable teens she noticed was the tall masked boy with an interesting hair style. For the most part, he seemed to be silent. 

Everyone she was in class with were odd, but it made the class seem more interesting, even if she were not to participate in anything that they did in generalized shenanigans. She smiled lazily before setting her head down on a desk not too far away from the door, though it was still in the back of the class. After all, though she could use her shortcuts, she could just take a short walk to the door to leave if needed. 

"Hey you, extra. Wake the hell up." A gruff voice sounded from behind Sans, annoyed and condescending. "How did you even get into this class anyways? You are practically a lump." More and more annoyed, what a pain. 

With a yawn, Sans woke up, her white eyes half transparent in the blackness that had made up the rest of her eye. He grinned cheekily to the angered teen, before laughing. "What's the matter there, pal? Got a BONE to pick with me?" her grin went from cheeky, to simply lop-sided. 

"Why you-!" The sandy-blonde haired teen grit his teeth before he went to pull his arm back. His anger flaring quickly. He grabbed the other girl by the collar of he shirt, the jacket tied around her waist lazily rather than kept over her shoulders. "Do you think this is some kind of fucking joke?"

Everyone in class was looking at them now. Sans just shrugged, still grinning as she closed her eyes. "I mean, if I didn't I wouldn't have said anything pal. ICE to meet you too, bud." 

"Why you-" 

Soon enough a caterpillar-looking man came slinking through the door. He said something, but Sans didn't quite hear it, despite not talking after her pun. The man crawls out of a yellow sleeping bag, his eyes also were tired and lazy. Bored. 

After a sigh, and a little bit firmer of a tone, he gains everyone's attention. "It took all of you 8 seconds to shut up and listen. You need to get yourselves under control. Now get up, we are going to the locker rooms to get changed. We have exams to take for your overall power levels and skill capabilities." 

Bakugo, in an annoyed fit, let go of the others shirt, and halfway shoved her back. After making his way to the door, he walks down the hallway, following the teacher. Sans, on the other hand, still sat there grinning before getting up, and carefully re-situating her scarf.

"Do you need some help?" The green haired boy walked over to the other, before extending out his hand in worry and confusion. "I am Izuku Midoriya. Sorry about Kacchan, he is very... uh... expressive." he mumbled. 

"I can tell." Sans took the others hand, before fully standing up again. "Besides, who am I to judge? Nice ta meet'cha kiddo. I am Sans. Sans the Skeleton." the normal greeting she had used with that child... she let it slip. 

"Kiddo?" Izuku seemed confused. He laughed a little nervously before looking away. "Never mind. Nice to meet you, Sans. Anyways, we better get going, the last person is almost out the door already." The green haired kid went to jog to the door, keeping up with the others in front of himself. 

Sans sat there for a moment, before sighing to herself and smiling a little bit. 

"Maybe my experience here won't be as bad as I thought." she caught herself thinking. "Just maybe."
