If you do not partake in CraftMine, it was a 'in a nutshell video'. Anyways, welcome to the chapter. I hope to get more chapters of this out soon. I do not intend for it to be that long of a book. Hopefully. //

Combat.... fighting. Something Sans had been used to for so long in her life she didn't think anything much of it anymore. She suffered thousands and thousands of timelines , those timelines entailing her and that brat PLAYER that had caused her all that grief. All the players had caused everyone grief. 

This was almost nothing in comparison, though some of the attacks were something she had not been able to get used to yet. She also was not terribly used to fighting more than one person at a time. Her on real saving grace on that regard was that the emotionally stagnant classmate of hers was there, keeping quite a few of them at bay.

He fought silently, barely needing to move, at first. Sans, on the other hand, was chatty. She easily made fun of the opposing side. Of course, most of the villains were quite the opposite of 'level-headed', easily provoked and tricked.

There was no easy way to make sure they stayed out of the way, so she had to do her best to knock all of the ones she fought unconscious, Todoroki deciding to do the same. 

"We need to make sure to meet up with everyone else soon. Do you get squeamish easily, Mister Cool?" Sans questioned to the other, before she quickly teleport to him. As soon as she re-appeared, she activates several of her bone attacks, catching many of the enemies off guard. 

It only took a couple more minutes, and all of them were knocked out, and secured by bone attacks, keeping them plastered to the ground. 

"Alright, let's gather up everyone we can, and try to make sure there is no issues anywhere else. Mister Aizawa hopefully has the man front under control, if that is where he stayed..." Sans put her hand on the others shoulder, before closing her eyes, and envisioning Bakugou. It took a couple tries, but she did manage to get both her and Todoroki where they needed to be. 

After several more attempts and failures, as well as successions, she had manged to get everyone in relative place, near Mister Aizawa. Midoriya, Mineta, and Asui were across the way in an ocean-like biome. They looked somewhat tired, but tense, and still ready for action. 

All of the students were on guard, ready to go in and help their teacher, who was now facing off against the blue-haired man. The man was cocky, and tempremental. Easily growing upset, as if he were a child. His plans were not playing out the way he thought they should have. The way he had actually planned them. It was making him livid. 

Sans stood behind the group, panting, and sweating from all of the use of her magic. Beads of cold sweat falling from her brow. Her white eyes were replaced with the blue-green flashing iris, and blue-tinted ghost fire. 

Everyone looked back at her, mostly in worry, Iida had yet to come back with help, but some did take notice that he DID get out of the building. 

Sans started to hack up blood, as well as bleed from her nose. She fell to her nose, wheezing from the extensive usage of her quirk. She had never needed to transport so many people at once. It made her inner system shake. She could feel her soul trying to pulsate to release magic though her human body. 

"Whoa, are you alright?!" Hagakure called to the white-haired girl in worry as she ran over to meet the other. "Guys, we need water or something. Not a good idea to leave blood sitting in her mouth!" the invisible classmate called out to them. 

"I think I can try to make a bottle of purified water for her..." Momo looked to the still coughing girl, taking note that it wasn't just blood that she was coughing up anymore. She was... coughing up ... powder?

Sans continued to cough, her body shaking. If she knew that making more than herself and a couple of people teleport at one time was going to do this, she would have tried something else. 

Momo quickly summoned forth some bottled water for the other, who was now on her knees over a pool of blood and white powder. 

"What the hell is this white shit?" Bakugo asked, looking at the girl in shock, covered up by annoyance and anger. He had never seen anyone cough up powder before... something else surfaced from the girl... bone marrow? Is that what it was?

Several other students felt a chill running up their spines. 

Momo urged Sans to lean back, both of the girls white eyes were missing, as well as the blue flaming ones that the other students had been barely exposed to. She drank the water when the black-haired girl urged her to. She shook a bit, and the blood stopped being produced. 

"Mister Aizawa is getting overwhelmed, we really need to find a way to help him. Half of us should stay with Sans, in case more villains come back..." Kirishima looked to the teacher again, seeing Midoriya interfere from where he, Asui, and Mineta were. Everything seemed to freeze when a large creature walks out of another mass of mist.

Everything was going so fast. Sans had seemed to recover quickly, though she was still tired. However, the second Aizawa ended getting damaged by the blue haired man, she lost it. She was up, and interfering from a distance. Using her attacks to deter the man. This, in turn only pissed him off more. 

This also made her a target. He sent the large creature after the group of students, and it was alarmingly fast. 

"Quickly, grab on again! I can't block this!" Almost everyone grabbed onto her jacket somewhere, though it was in apprehension. She had ended up damaging herself seriously somehow because of transporting all of them before. 

"Are you a fucking idiot? Transporting all of us before turned you into a useless lump before! Do you seriously expect us to do this again?!" Bakugo yelled out to her, causing the girl to roll her eyes, seeing as they were back again. 

"I fucking swear, you are like one of angry little dogs that people stick in their purses for show." Sans stated to him. As soon as he went to yell at her for the comment, she grabbed his arm, and closed her eyes, making them all teleport to the general area of where Midoriya and the other two were. 

As soon as they reappeared at their destination point, everyone fell to the ground from about 2 feet above where they were supposed to be. Sans was unable control a full transport for them, but at least they didn't get hurt. 

The second they showed up, all of them took notice of the blue haired man. He had been charging at Asui, who was unable to move. They saw what his touch did to their teacher, if he got a solid hold on the frog-quirked classmate, there was no telling how horrible it could turn out. 

Sans quickly sets loose one of her bone attacks from the ground, causing the chapped-lipped man to be sent flying up a bit, seeing as he was not ready for it. 

During the vast amount of movement, Sans had barely noticed that her brothers scarf had come out from where it was tucked in her training uniform. 

As some of the other students had went out to help out Aizawa, a lot of pro heroes started to show up, using their attacks to secure unconscious villains, as well as the ones that had not been caught. 

Upon falling on the ground, Shigaraki growled in anger as he had been interfered with yet again. He charged forward, arm extended out toward Sans face. The girl, however, quickly moved back. He didn't completely miss her, though. 

Shigaraki had gotten a hold of Sans scarf. As soon as his fingers closed around it, the immediate area around his hand started to turn gray, and slowly crumble. Sans felt her eyes widen, quickly pulling herself back to try and get away from him. 

He, however, tightened his grasp, and the scarf started to decompose faster. Sans finally frees herself, falling back, and landing on the ground. The damage had already been done though. 

Her brothers scarf was no bigger than a bandanna now, dirty from various fights they barely missed on their way here. 

The scarf was essentially ruined...

A loud, agonized scream sounded over the training grounds. Most people were surprised about the source. After having known her for a considerable, yet short amount of time, most would have thought such a sound to come from her was impossible. 

The girl screamed as if agony was her only known emotion. The voice behind it was broken, disbelieving, and in utter anguish. 

"PAPYRUS!!!"
