Sans used his powers to teleport himself and the others into a classroom, as Professor Port looks at Sans, and spoke out.

"I didn't think that you were going to show up this early, Mr. Gaster."

But Sans could easily tell that Professor Port was actually hoping for that to happen, due to the tone of his voice, and Sans simply just shrugged it off, as he than simply just walks over to the table that he is sitting on, and sat down on there, as Papyrus sat to the left of Sans, and Ravel sat to the right, and held his hand along the way.

This made Ravel blush at what it is that she is doing, and Sans also blushed. But he does not hold it against that sort of thing, as he than squeezed her hand around Sans' to show how possessive that she is of Sans. And Sans kind of does the same thing, as he blushed a little bit brighter than Ravel. But this makes Ravel much more happier with what she is doing, as she is able to see that Sans does have some feelings for her, which is what she has hoped to happen.

Sans scratched his chin in awkwardness with his left index finger, his eyes glowed a little bit, as he looks down at his hand, and tightens it, though his grip is no match for Ravel Phenex's own grip, which is many times more stronger then even Sans' own grip, which is really saying something, as Sans' Evolution allows him to have magic that surpasses that of even Ravel's Phenex's own devil magic, and he has a much more stronger form of immortality compared to Ravel, as well the fact that he is a bit more intelligent compared to Ravel, at least when it comes to science and all that.

Yumi and Minori sat at their own spots, and the moment they did, they looked at Sans with a blush in their faces completely shown. Sans looks down at Yumi and Minori, and he smiled too, with a blush of his own present for them to see. But despite this, he acts very happy too then, and he does not have them worry for his life that much, as this is his own way of reassuring to them that he is not going to be killed or something like that.

But than, the other members of class came in, and they looked up to see that it is nothing more than Sans and his friends, who have arrived first. Luckily, though, Yumi's team, as well as Team Hanzo, we're the ones to notice them first, and sat around them as fast as they can, so that the people that hates Sans so much do not use their seat positions to try and get a good shot at Sans and try to hurt him while he is in class, which is what the students are hoping to do, so that Sans would get in trouble.

This made Sans breath happily, as he than looks down at his desk for a second, before he than looks back up at Professor Port, who is looking at Sans with a rather annoyed expression present on his face, before he than starts his class normally.

And the class started, and Sans paid attention to the class in the fullest effort that he can, along with Papyrus, Ravel, and Yumi. Minori, however, is still as hyperactive, due to how immensely childish she is, but Sans does use his scarf to calm her down, by extending it and patting her on the head, in order to try and calm her down. And Sans does this without looking at Minori.

Of course, most of the students, notably Issei, barely pay attention to this class, and most of them are simply mostly right in the tests that they have gained, half-correct on their stuff, or simply just mostly wrong in what they have. But Papyrus, Sans, Yumi, and Ravel get it right. And of course, Sans has to whisper some stuff to Minori in order to help her get the right answers on the pieces of paper that she has. And the ironic thing about this, is that, Sans is one of the students that Professor Port really dislikes, due to his supposed-weakling status. And yet, despite that, he is also one of the top students in his class that can get his essay done without any wrong answers of any sort. It is an embarrassment to Professor Port, and yet, he still takes this without any complaint, as while he does not like Sans, he does at least act fair and gives Sans the benefit of the doubt, and allows him to pass his class, unquestionably. While for Issei...he will have to take the test again repeatedly until he got it right. And needless to say, Ravel Phenex and the other members of Sans' friends are really proud at the fact that Sans is able to pass this class without any sort of trouble and without any sort of effort. But Ravel, of course, is able to do the same thing, considering that she herself is very intelligent and does not hold back on how intelligent that she really is.

After the bell had rung, Sans, Papyrus, and the rest of Sans' crushes all came last, as Sans and Ravel went next to each other, as Sans spoke out.

"That is very really good on how much you got done on that piece of paper, Ravel."

Ravel blushed, as she than spoke out to Sans.

"Oh, please Sans. You are also just as capable as I am in that area."

Sans smiled, as he than looks at Papyrus and his brother did a thumbs up, meaning that he has aced it as well. Minori and Yumi are simply behind Sans, as Minori hugged him from behind, much too his embarrassment, but he does not object. As Sans and Papyrus walked, Team Hanzo came to them, as the leader of that Team spoke out to them.

"Papyrus, good to see you!"

Papyrus looks at the group and smiled at them, before he than spoke out.

"It's nice to see you too my friends! How are all of you doing this time?"

Hibari smiled, as she bounced a little happily, and she than spoke out.

"We're doing so great ourselves!"

Ikaruga than spoke out to Papyrus.

"We are doing very well, and having been training a lot more, thanks to some rather, competent teachers."

Papyrus smiled, as he spoke out to them.

"I'm very happy for all of you! Shame that me and my friends, and my brother, had to go some ineffective teachers."

Sans snickered a little, along with Ravel at what Papyrus said, as Yagyū than spoke out to Papyrus.

"Paps...do you mind telling if that group had been targeting Sans again?"

Whine Yagyū may think of Sans simply as a friend, to Yagyū, he is like a brother to her, and will do whatever she can to make that person pay for what they would do to Sans, namely, Issei, who she really despises so much, due to the fact that he tries to act perverted to Issei, and the way he did it is worse than Katusragi. Luckily, Papyrus was able to team up with Yagyū and bats Issei away before he can truly corrupt Hibari, but than she would learn that Sans would be subjected to Iseei's harassment, and would defend him sometimes when she is with him, and one time, forced Blake into a sword right against her, in which the Cat Faunus lost against. After Hibari, Sans is the one person that Yagyū thinks as family to.

Papyrus nodded his head, as he than spoke out.

"They did, but Sans was able to stall just enough time for me, Yumi, and Ravel to come to him. And Sans was not even afraid of them. According to Yumi, all Sans did was mock them in their faces, and he did not even hold back in what he think is them, whine also getting more hurt."

This made Katusragi smile a little bit, as he than spoke out.

"Really? Hah, you must have taken my word heart, little dude."

This made Sans smile a little forcefully, as he spoke through gritted teeth.

"Gee...I wound be thankful if I was not so frustrated with what you have called me."

This made Katsuragi laugh at the reaction that Sans had. But of course, she is also laughing at the fact that Sans had locked his bullies continuously.

As he said that, another pair of female voices spoke out.

"Yumi, Minori! There you are!"

Minori and Yumi turned to see that it is none other than the rest of their group.

Needless to say, Minori was happy, as she than comes in and hugs the members of her group, extremely happy to see them. And Sans was also smiling, as Yozakura than spoke out.

"Hello, Sans. It seems that you are still as good as ever."

Sans nodded as he spoke out.

"Yeah, defiantly. You too."

While Sans are close to the other members of Yumi's team, it's not to a romantic point. Not that it stood Shiki and Murakumo from flirting with him, though these are now genuine feelings, as it is just to embarrass him. But nevertheless, Sans is having a very good time in seeing some old friends again. Especially since it is a very long time since he had been with them from all of the problems he's faced.

Later...

Sans and the others are now in Combat Class, and it is lead by none other than Glynda Goodwitch.

And needless to say, Glynda is one of the few few people that does not hold back on how she doesn't like Sans, as she actually tries to make the match as unfair as possible. The past times that she had tried to put him in an unfair match, she would put either Bakugou and Shota, or Yang, or Koneko, many of them are more powerful students, and sometimes teams, in order to stop and defeat Sans, but he always was somehow able to beat them without trouble with the use of his magic. So she decided to do one match, after this one.

In the arena, Yang is shown to be punching Bakugou so hard, that he is sent flying backwards as far as he can, and into a wall, and this is before the timer ha reached the limit, and declared it over. She than spoke out to the students, as she than spoke out.

"Next up, Sans will be fighting against Rias and her peerage. And Sans, if you are back down from this match, you will get a detention for an entire 4 days."

This made Sans angry, and before he could speak out Ms. Goodwitch, someone already beat him to it."

"Hold it, Ms. Goodwitch!"

This made Glynda Goodwitch turn to Papyrus, as he than spoke out to the teacher of combat class.

"I'm going to join in with Sans, so he will not have to do this alone."

Glynda Goodwitch was about to retort to Papyrus, before Ravel Phenex than steps in and spoke out.

"I'll join in as well. After all, it is not fair that one of the students has to fight an entire group. It is time he has a group of his own to make this a little more fair."

Glynda Goodwitch was thinking of retiring, but seeing the time, and the fact that it is about to end, due to 3 other very long matches, she snarled a little and glared, but she than sighed and spoke out.

"Fine. You both can join."

This made Papyrus and Ravel Phenex feel relieved, as Ravel puts a hand on Papyrus, and teleports right next to Sans.

Papyrus and Ravel Phenex stood tall and proud, as Sans spoke out to them.

"Thanks, guys. I really needed this."

Ravel Phenex and Papyrus smiled at Sans, as they than turned back to Rias' peerage, as all 3 of them then got ready to fight against them.

And needless to say, the peerage aren't happy that Sans will be doing the fight all on his own, and will in fact have people that is by his side. Needless to say, Rias spoke out.

"Fine than, if you want to fight side by side, then you all will be defeated together!"

Ravel Phenex than spoke out.

"That is too bad for you, Rias, because with us by Sans' side, we will make sure that you and your peerage are defeated!"

This made Rias snarl, as Issei than spoke out.

"I'm gonna fuck you up for your insults towards me, weakling!"

But Sans simply smiled, as he than spoke out.

"Try me, you brainless Dragon Emperor."

This made Issei angry, as Glynda Goodwitch than spoke out.

"Let the match, start."

As soon as she said that, Yuto Kiba then made his first move, and tries to swipe his sword at Sans, only for Sans to notice it, as he than dodged the attack, and he ducked down, and as Kiba rushes at Sans, the small bird boy than puts his foot out, and Kiba trips to the ground, and accidentally cuts himself a little bit, though not to the point that it makes it very serious. In fact, as soon as he tries to stand up, a Bone was summoned from Sans, one that is empowered with the magic of the CELL Core, and when it hits Kiba, it paralyzed him, incapacitating him from the fight. Because of this, Rias has just lost one of her component members, as Koneko than goes into a fight with Papyrus, as he blocked her punches, before he return them back at full force, in order to cause as much pain to Koneko as he can possibly dish out. But Koneko is doing all that she can to not get hit, as she than launched a Senjutsu ball at Papyrus, who than responds by extending his hand out, and launched a bone, cancelling the attack. She than flies up into the air, but Papyrus than used his Blue Magic to force her back down to the ground, making her stand up and fight on foot, doing nothing more than jump and dodge, though she can still use her fists. She punched Papyrus in the head, before kicking him in the stomach, before she is then grabbed by Papyrus by the leg, and is thrown back, as Papyrua fired a bunch of bones, pinning Koneko to the wall, and made her go out of the ring. Needless to say, this is making Rias angry, as Xenovia charged into the fight, and tries to attack Papyrus, only for Papyrus to suddenly, as Sans' Abyss Blaster, right in front of Xenovia's face, before the Abyss Blaster fired, and attacked Xenovia directly, sending her backwards and crashed. Rias snarled, as she spoke out

"How dare you, you little bastard!!! Akeno, Issei!"

Both nodded, as Akeno held her hands high, as she than spoke out.

"Oh, Sans, let me hear your screams!!"

She than fired an attack into the air, and tries to strike at Sans with her holy lighting, only for Sans to summon an Abyss Blaster above him, blocking the attack, before Ravel than flies up into the air, and launches a fireball at Rias, while Rias launches her Power of Destruction at the fireball, destroying it, as Rias spoke out.

"You cannot beat me, Ravel!"

But Ravel simply has a smug smile present on her face, as she than spoke out to Rias Gremory.

"I think I can, Rias. I think that I can."

With Issei, he is shown to be charging at Sans, as Sans was continuing to hold his ground against the Holy Lightning, before it stopped, as Papyrus fighting against Akeno in physical combat, and Sans can finally catch a brake in defending against Akeno, as he the then charged at Issei, before he than launched a powerful kick at his head, before a punch in the stomach, and an uppercut at the jaw. While Sans isn't physically strong, even with all of his physical training, he does have enough strength to make Issei stagger a little, as Issei than fired a Dragon Shot at Sans, before Sans than held his hand out, and fired an Abyss Blaster, which overpowered the Dragon Shot, and exploded, forcing Issei to slide backwards from the immensely powerful shockwave. Issei than boosts his power, before he than charged at Sans, before Sans spreads his scarves; and flies in the air, and he fired a bunch of Cell Bones quickly. But Issei than fired a Dragon Shot at the bones, destroying them, before Sans flies a little backwards, and the Dragon Shot misses Sans, as Sans looks down at Issei and smiled at him, in an attempt to mock him, and this made Issei angry, as he than spoke out.

"Balance Breaker!!"

"WELSH DRAGON, BALANCE BREAKER!!!!"

Issei than leapt up into the air, as he transformed into the Scale Mail armor, before flying up to try and agonize Sans painfully. But this time, Sans knows better than to stand still, as he flies out of the way, before he than began to fly all over the arena, as he than fired his Abyss Blasters at Issei, in an attempt to try and defeat him. But Issei fired his Dragon Shots, and holds the Abyss Blaster's fire until he passed them, in which the Abyss Blasters will miss and attack the shield.

Rias than looks up at the fight with Sans and Issei, as she spoke out to Gasper.

"Gasper, stop time!!!"

Gasper nodded his head, as he opened his eyes, and stopped time in the area...as Ravel and Papyrus were affected by the attack. Than, Sans spoke out.

"What have you done?!"

Rias looks up, and saw that Sans is unaffected by the Forbidden Balor View, showing that he is resistant to its power. As Rias than spoke out.

"That won't be important, once you're done for!!"

She than fired her Power of Destruction at Sans, who ducks, and he than returns fire by attacking with his Abyss Blaster, before Rias made a magic circle to block the attack, and Sans dodged a punch from Issei, who than spoke out to Sans.

"Give up, weakling!! You cannot defeat me!!"

But Sans smiled a little wider, as he than spoke out.

"Who says I have to be the one to defeat you in a fight, when I can do this?"

He points behind Issei, and sees that Papyrus is also unstuck, due to the fact that he simply pretended to freeze, and tackled Issei, before beginning to pummel him into the ground as much as he can. He than turns back to Rias, who than launched her Power of Destruction at Sans, and in return, Sans fired his Abyss Blaster, which overpowered the Power of Destruction as much as he can.

He than fired a Cell Bone at Gasper, and hits him on the head hard, though only to the point of knocking him out, who allows time to continue, freeing Ravel Phenex, who than shook herself, and realize what has happened, before she than targets Akeno, by firing a bunch of fireballs at her.

The fireballs exploded, and Akeno was knocked out of the ring, as Ravel Phenex landed on the ground, before Papyrus than punched Issei back to Rias, as he skidded on the ground. This made Issei angry, as he than spoke out.

"You fucking bastard, I am going to-"

But before he can finish, the bell rang, singling the class' end. Needless to say, Rias and the conscious members of her peerage are not happy with this, and the same goes for Glynda Goodwitch, who was hoping for Sans and his group to lose, but knows that there is nothing that she can do. So she than signaled everyone to finally leave to the next classroom.

Sans sighed, as Ravel Phenex and Papyrus than walked with Sans, as Papyrus then spoke out.

"You did very good up there, being able to stalemate Rias and her peerage."

Sans nodded, as he than began to walk along with Ravel Phenex down the hallway, as he and Papyrus began to talk some various stuff, as the students continue to insult Sans, but Sans does not care, as he and his brother and friends continue down the hallway without bother. But as Sans and the others continued to walk down, suddenly, a Dragon Shot nearly hits Sans at the head, as Sans bent his head a little to talk to Ravel more clearly, only for him to notice the shot, which blasted at the wall. This made Sans frustrated a little bit, as he spoke out.

"Here we go again."

He then turns around and sees that Issei is there, and he looks extremely angry, as he than spoke out.

"You!! You are going for making Rias look bad, you little midget."

Sans than spoke out.

"She already does look bad, not to mention act bad. I can barley take her attitude."

This makes Issei angry, as he than tries to grab at Sans by the neck, only for Ravel Phenex to launch fire at Issei's hand, burning his hand a little bit, before Papyrus grabs Issei by the throat, before he than swung his arm, throwing Issei far away to the point where he will take him a minute to fly back to where Sans and the others are at. And it seems that Team Hanzo, and the rest of Team Yumi are gone, most likely on some mission of sorts that they are needed to do for utter importance.

As that happens, a voice calls out from the radio that is above at the top part of the wall.

Will Sans Gaster comes to the Headmaster's office?"

This made Sans frown a little, as he than spoke out.

"Why do I have a very bad feeling of what is about to happen next?"

Papyrus than spoke out to Sans.

"Do not worry, Sans. If something bad happens, I will help you, even if it means fighting against the Headmasters and the army of students that are trying to attack you for no reason."

Sans looks at Papyrus and smiled, before he than looks at Ravel, who smiled at Sans, and kissed his cheek, before Sans than teleported away. He than opened his eyes, and sees that he is in the Headmaster's office, as he than looked and sees that they are looking at him in disappointment. These Headmaster's are Sirzechs Lucifer, Ozpin, Nezu, with the other one, Kiriya, missing. Must be because he is on a mission along with the Shinobi. He than spoke out to the headmasters.

"What is it that you want, after all of the ignoring that you all did to me and my suffering?"

But then Ozpin spoke out to Sans.

"Do not give us that tone, Sans. Especially since you had now shown progress in your powers."

This made Sans spoke out in confusion.

"What do you mean? I made a lot of progress in my talents. Hasn't it shown on your screens?"

Sirzechs than spoke out.

"No. There is not a single thing shown of your improving on what you have done. In fact, all it shows is simply 0, meaning that you have no use in Union Academy."

This made Sans stunned...as he then looked down, as Nezu spoke out.

"So in conclusion, you are not needed here. You are useless to Union Academy. Meaning...you are expelled from Union Academy, and are never coming back."

This made Sans angry...but he than has a smile on his face, as Sirzechs spoke out.

"Which means you will leave in a minute...before the guards force you to-"

"So that's what this all about?"

Sans suddenly spoke, as he than looks up...and his eyes began to glow...before Ozpin spoke out.

"What do you mean by-"

But before Ozpin could finish speaking, Sans spoke out.

"All this time...I thought that Union Academy was made to protect the weak, to train heroes so that they can defend the innocent lives that can never fight back, to protect those that cannot protect themselves from any form of danger, to care for the powerless that are unable to do a single thing to help out others."

And Sans than smiled, as he than began to glow.

"But now...now...I finally see it...your true colors. You never cared about the innocent lives, nor the powerless. You care more about power, fane, glory, wealth. And that is all you and the other heroes care about. That is why you all left me to my painful torment...all so you all can prove that I am weak...when it comes at a cost. So you know what....fine then...but there is something you should realize."

He than has DNA Markings on his eyelids, as he than spoke out, and the Headmasters become concerned, as Sans spoke out.

"When I was still accepted in Union Academy..I vowed to bound myself to its rules, to always follow how many rules, no matter how unfair it may seem, and how biased it is, except for the ones that involve being discriminating to the powerless. But since you've expelled me...I am no longe bound by it."

He than raised his hand, and snapped his fingers, and revealed the Abyss Blasters, 3 pointing at the Headmaster of Union Academy, making them all stand up, as Sans spoke out to them.

"Which means...I am not bound in attacking all 3 of you."

This makes Ozpin a little worried, along with Nezu, who is actually looking scared, as Sirzechs spoke out.

"No, you wouldn't dare!"

But Sans smiled...as he than spoke out.

"Oh...but..."

He than opened his hand, as the Abyss Blasters readies itself, and charged it's attack, and Papyrus, sensing it, along with Ravel, immediately grabbed Yumi and Minori, before teleporting away outside, as Sans smiled at the Headmasters.

"I do."

He than aimed the Abyss Blasters down at the ground...and closed his fist...and the Abyss Blasters fired down...aiming at the energy core that powered the building...and exploded it.
