Back to School

// Alright guys, after a long, notable weekend and lack of production, I am here with another chapter. I hope to have it finished soon, so it can be posted. However, if I do not upload in a couple of days, it is because I am in the middle of homework, or I was distracted and did some art stuff while I was away. Either way, here, HENjoy the chapter, and don’t forget to sIkE n lUbscribE to My tUbeyOu chAnnEl. //

The night passed in a comforting silence that Sandra could only wish she was able to enjoy when she was at home alone before. Knowing that the others were there too was one of the most comforting things to her. It made her feel like she wasn’t isolated. She didn’t need to hide anything from them, because they already knew her.

In the morning, Sandra woke up to her alarm, which, at this point, was placed in the center of the room. All of the other Sans variants were still asleep in their sleeping bags. Sandra wondered how she even got used to waking up to alarms, but at least it wasn’t impossible.

Why wake them up like a normal person when she can have a little fun with them though, right? Smirking to herself, the white-haired girl stands up, and walks to the kitchen. After letting her bare feet adjust to the cold tile of the kitchen floor, she walks over to the counter, where a frying pan rested on a towel. She had set it up the night before, that way she could make breakfast for everyone when she woke up.

Pulling her hair out of her face and tying it back (she did step away from the stove, so no hair fell out onto the burners or anything). She grabs the pan, and a metal spatula that she had in the top of her cooking utensils drawer, and walks back into the room. After carefully walking over all of the others, who were sound asleep, she smirks, and brings the spatula and pan together with a thunderous clap.

Dust woke up in such a start that she activated her magic eye, looking around in a panicked worry. Sandra could have sworn that she heard Dust’s Megalovania playing somewhere in the torn shreds of time and space. Maybe.

Nightmare had woke up as if nothing had even happened. She just opens her eyes, sits up and rubs the sleep from her tired eyelids.She looks over at Sandra and sighed, before letting a small smile across her face in border-line amusement, and the smallest tinges of annoyance. After taking a moment to finish waking up mentally, she stands up from her bed, and folds the blanket neatly over her space.

Horror woke up, still almost fully asleep, and ran like there was no tomorrow. Horror was so tired, and unpresent in mind that she ran into the door. It was like she didn’t even notice. At least running about 28 MPH (Which is the average speed of humans) into a door that was quite a few yards away woke her up though.

Walking over to Horror, Sandra looks down to the already apparently battered version of herself, and extends out a hand to her. “Hey Horror.”

“Hey Classic.”

There was a small silence as Sandra helped to pull Horror off of the ground. “So, uh-”

Horror sighed, and smirked at the other, before letting out a bit of a chortle. “That hurt.” She knew it was going to answer Sandra’s question. Rubbing her head, the damaged version of Sans took a moment to gain some better composure before even thinking about moving from this spot.

“Sandra nods, before patting the other on the shoulder. Before she could make it too far away though, Horror grabs her by her arrm, and drags her back. Not wasting any time, the enthusiastic and dangerous Sandra a hard noogie, lightly scolding her for scaring her so much.

Sandra laughs in return. She walks to the kitchen, deciding to finish up with making breakfast for her counterparts. All of them clean up their sleeping spaces, in the kind mind of being able to help classic out a bit.

-

Reaching school, the girls are all greeted at the doors by class 1a, and several pro-heroes, as well as teachers that didn’t work until the afternoon because of their busy schedules. All of the girls look around in interest, if not some kind of wonder.

Something struck them, none of them really practiced trying to figure out their ‘quirks’ as they call them. Mainly to see if there was anything else they would have been able to do during the fight. Killer, Dust and Horror were going to be the most similar ‘quirks’ to Sandra, seeing as they did not have too many special powers.

Nightmare, Error and Cross, however, were a different story. Cross had a giant knife, the ability to control enemies by slashing them with her knife without killing or maiming them. She could also summon up a ‘form’ of Chara, if she really wanted to. The ‘form’ or ‘shadow’ of Character worked as a doppelganger or a minion of sorts.

(Disclaimer: I do not think Cross can actually summon up a ‘mock/shadow/minion’ version of Cross!Chara. It is just something I added to make Cross seem a bit more unique. As stated though, it is a ‘mock’ version of Cross! Chara. So it is not the real entity.)

Error had the ability to still use a sort of ‘portable pocket dimension’, however, it was not something to be confused with the anti-void. Error could only pull something into the pocket dimension for as long as she would be in there. If she came out of the pocket dimension, so did the enemy she had taken in there.

There was no limit on who all she could take in there, though. Which was a good thing.

Nightmare was ‘freakishly persuasive’, one could say. She was already very powerful, but she still thrived off of fear. It does not do as much to her ego, or self control as it used to. She was relieved about that. Her keen sense of human or monster nature was useful in turning enemies against each other, that way they became each other’s problems rather than her or her teammates’.

Other than that, she does have the retractable appendages on her back that can help to sense and attack or grab enemies that were nearby. The tentacles that rested on her back were able to sense movement, and heat, or cold. However, they did not feel too much pain, unless they were severed REALLY close to the back. If the Tentacles were actually cut or severed, it takes them about 10 minutes to accumulate enough energy for them to reform themselves.

All of the teachers greet the girls, some with more… enthusiasm than others. The students of 1a all stood near the door, somewhat relieved to be getting part of the day off from schooling. The tournament left quite a few of the students still fairly tired and worn. Kirishima was walking awkwardly because he had hurt his leg a bit.

He and Tetsutetsu, a boy from class 1b, seemed to be getting along quite well, though. Practically best friends already. Sandra goes over to stand by her class, and catches sight of Iida, who looked even more tense and vengeful than he was the day before.

Walking over to him, leaving her friends to listen to the small lecture, and verbal ‘terms and and agreements’ of this course, she greets him with a small wave.

“Hey there, speed machine. Are you doing alright?” She leans against the near wall of the doorframe, seeing as they had no real reason to move along with the rest of the class yet. “You seem pretty TENTS.” The joke was subtle, but still there.

The bluenette seemed to give her a cold glare that signified that he was not in the mood for games, but he looked away just as fast, realizing just how rude it was for him to give her such a look. She was just checking on him to see if he was okay, after all. There was no harm being done, so she did not deserve to be looked at the way he had done.

“I am sorry.. I did not consider my actions when I looked at you in such a manner.. But… I am sorry. I cannot tell you anything, I am uncomfortable with it. Maybe I will tell you at a later time…?” Heh, that seemed to be a question to even himself, at this point.

“Oh, alright. That is understandable, you do need your space. Not to mention, you do not know me that well, so there is less of a reason to talk to me about this. I hope whatever happened gets better. I understand life can be hard sometimes, but it just depends on how you persevere through it.” She walks back toward the front of the class, waiting near the teachers who are still talking to her friends about the beginning exam.

They had to get a condensed version of about 2 years of lessons and other info that Sandra had taken in junior-high school of her classes. They were trying to make sure these girls stayed near Sandra if they could though. That way nothing happened.

Aizawa somewhat found himself hoping that they would be assigned to his class, depending on their skill levels and abilities as well as cooperation and coordination. He needed to make sure they would be ready to be in the harder courses. If they needed a bit of a lighter class though, they would be assigned to the class of 1b. That was, of course, if they actually passed. Just knowing that they were related to Sandra, though. Be it by blood or by exposure and friendship, they were more than capable of taking care of themselves.

Sandra was a really tough, compassionate, and powerful kid. Especially for her age, it is surprising that she can hold up a fight so well. Maybe her affinity for laziness and relaxation was the reason why she had such an easy time finding ways around requirements without breaking the rules. Of course, all of the teachers still had questions. One’s they were not sure they should ask.

Beru Asui and Ganma Asui, Tsuyu’s parents, were still on high alert and constantly fretting over Sandra. (Mainly Beru, but it was clear that Ganma cared.) However, they were as patient as they could be. They would continue to be so, until the time came, even if it never did.

“Alright, girls. Please tell me your names so I can put them down on the clipboard. I want to make sure to analyze the skills, and overall compatibility you have with each other, and what you would be able to bring to this school in your efforts to become a pro-hero.” Nedzu smiled up at them after extending a hand to shake with them from where he was at.

All of them were dumbfounded at first, but it was certainly not the first time they had seen anything TOO surprising. Really, it wasn’t. So, in her typical leaderly way, Nightmare had gone first. Using her common formalities for decent conversation. She was not going to suck up to him though, like many of the formal type seemed to like doing.

“Greetings. I am Nightmare.” She stated in a curt, but more-or-less polite manner. The rodent looked up to her with interest, and confusion.

“What is your last name, Nightmare? That way I can get it down on the track-sheet for your progress.” The small mouse-like bear seemed to be enjoying himself.

Nightmare paused for a moment. She didn’t have a last name. None of them did, actuall, so what was she supposed to do? What could she say to this principle to show she did not have a last name, but not make it seem so suspicious, or awkward? Wait, uh, central-asian countries don’t always have surnames… right?

“It’s just Nightmare. They also don’t have sur-names either. Uh… our ‘parents’ were very much American. However they were weird, and wanted to be cool by following something that was based supposedly off ‘Central-Asian’ cultures from articles that they had read online. So we all only have a first, but no last names.”

The mammal seemed more curious than simply stumped. However, he bought it, for now, and continued on his way to get the other girls’ names all on the list for them to conduct the entrance exams.

All of the students from Aizawa’s class made their way over to the training ground that was used before, a safe and notable distance from the actual school. After everyone was set up, all of the students get to a small, special building where they can watch the fight on the monitors in good safety, in case something did go wrong.

Sandra was confident in her friends though, mainly because she has had to fight every single one of them before. She had the hardest time with Dust and Horror, just because of their ever-lasting persistent and stubborn nature. They were going to be just fine.

-

After some basic rules and generalized training, the practice battle for the girls finally starts. With a mechanical whirring, and cheers from the students behind the monitors, the giant robots were let loose in the training area for them to fight.

Bakugo sulks in the back, but keeps his eyes on the screen. He was still sore from his ‘unjustified’ win.

Sandra was at the front of the class, cheering like one of those American ‘soccer-moms’ that were often mentioned in TV culture and commercial revenue.

The rest of the class were fairly active in their cheering save for Jirou, Tokoyami, Koda, and a couple fo the other students who mainly cheered in uptomost modestly.

The robots make their first moves.

This was going to be epic.
