Chapter 2: Welcome To Class 3-E

As the days went by, Gohan could feel himself getting more bored by the minute. Thankfully though that wouldn't last too much longer as he was scheduled to leave any day now. He just didn't know when since the days were beginning to blend together for him.

Things definitely got a lot better for him after his little talk with Mike and General Howser. For starters, they finally let him out of that hospital room to roam around the base and socialize with the workers there.

Not only that, but, after telling General Howser more about his alien background, he was allowed to eat to his heart's content as it became apparent that he needed extreme amounts of food to keep him healthy.

So, as Gohan was once again gorging himself in the cafeteria, he sensed the familiar ki of General Howser entering the room. As such, he and everyone else in the room did a small salute to the man before continuing with their meals.

General Howser paid them no mind though as he had important news for a certain young demi saiyan. With that in mind, he headed straight for Gohan's table where he saw the boy stuffing his face with some noodles.

"Hello Gohan. Can I talk to you for a moment?" the General asked respectfully before sitting beside Gohan after seeing him nod.

"Is something wrong General Howser?" Gohan questioned as he swallowed the last of his noodles.

"No, nothing's wrong. I just wanted to let you know that you'll be joining the octopus's class tomorrow morning." Howser told Gohan making the young boy smile in excitement.

"Yeah, I'm ready. I'm looking forward to it. Since I was homeschooled my whole life, this will be my first time going to a public school." Gohan said with a smile making General Howser release a small chuckle before getting serious.

"I understand that you're excited and I'm happy for you but I need you to remember why you're going there in the first place." explained the General making Gohan get serious as well.

"I remember. I'm still going to try to find a way to keep him from destroying the world. I won't kill him unless I think it's absolutely necessary." Gohan stated in a serious tone as Howser nodding in acknowledgment.

"I know. I just wanted to make sure you didn't forget. One more thing though. Will you be needing us to transport you to the school or will you be able to sense where he's at with your abilities?" General Howser asked but Gohan merely shook his head.

"No, I tried to sense him out. Someone who is strong enough to destroy is normally easy to sense but I can't sense anybody nearly strong enough to do that. It's possible that he knows how to suppress his energy though. Some people from where I came from can do that too. That includes me too. Not only that but it's possible for people to not even have a ki at all but they'd have to be an android or something like that." Gohan explained with a little bit of distress.

"I see. That could be troublesome but I'm sure you'll be able to figure it out once you see him personally. So, since you can't sense him and have no idea where to go, we'll take you to the school first thing in the morning. You should go to bed early tonight so you can get enough rest for tomorrow." said General Howser as he got up to leave and do some other stuff he had to get done.

"Ok, I will. Thank you for everything General Howser." Gohan said with a smile that Howser responded with a nod and a smile of his own before he left.

'Alright, I guess I should finish eating, do a little bit of exercise in the training area, get a snack, and then go to bed. I wouldn't want to sleep in tomorrow.' Gohan thought to himself as he started to eat some ham.

In the Class 3-E faculty room

A young man was sitting at his desk on his laptop. This man was Tadaomi Karasuma, otherwise known as Mr. Karasuma.

Mr. Karasuma was a man of average height. Not only that but he was muscular as well due to his time in the Air Force Military. He had spiky black hair, dark eyes, and slightly tan skin. Even though he worked as the P.E. teacher for the small class, he always wore a black suit with a white undershirt and a black tie.

His job as the P.E. teacher definitely had its ups and downs but he couldn't really complain about it. It was his job that he was ordered to do so he'd do it as professionally as he could. That didn't mean he didn't care about his students though.

As he sat at his laptop though, he got an unexpected e-mail from his superiors.

The e-mail said that there would be a third transfer student that would arrive before the second one was scheduled to arrive and that they would be arriving in the morning.

It also said that while the other student would be their trump card, this student would be their backup trump card if all else failed.

"Hmmm..." Mr. Karasuma said as he e-mailed his superiors back saying that he understood.

The next morning

"Alright class, according to Mr. Karasuma, we have another transfer student joining us." announced Koro Sensei. Koro Sensei was certainly an unusual one. Not only was he abnormally tall but he had yellow skin, tentacles, a very large and round head, beady eyes, an extremely large never fading smile, and he could change his skin color.

He also wore a black academic dress, a small and black academic cap with a yellow tassel, and a large black tie with a yellow crescent moon on it.

This "man" was the assassination target of not only the entire world's governments, Class 3-E, and more recently, Gohan. He was also going to be Class 3-E's and Gohan's teacher for either the next few months or until the planet had a date with death itself.

This unexpected announcement from their teacher sparked some chatter between the students and who it could be. Some even said it would probably be another assassin. Sensing that he had to get the class's attention again, Koro Sensei decided it'd be best for him to continue.

"I made a bit more trouble for myself than I bargained for underestimating Ritsu, so rest assured that I won't be making the same mistake twice." declared the teacher while pointing at the aforementioned student making her giggle.

Ritsu, was very different from other people, even in her own class. This was because of one main reason. That reason being the fact that she was an artificial intelligence program on a large rectangular robotic casing with a computer screen and an assortment of weapons within her physical "body".

Thankfully though, her creators also gave her a virtual body that would manifest within the computer screen itself. This virtual body had pale skin, light blue eyes, a gray school uniform, a white hairband, and short lilac hair with two longer strands of hair in the back that went all the way down to her hips.

"But, I encourage all of you to see the new addition to our class as one more potential ally." continued Koro Sensei as he grasped his tentacled hands together in excitement.

"Hey, Ritsu, have you heard anything? I mean, since you're both new, I figured you transfers got to stick together, right?" asked a female student that sat directly in front of Ritsu.

This girl was Sumire Hara, otherwise known as just Hara. She was a somewhat chubby girl that a short brown pony tail with bangs the drifted to the right side of her face, brown eyes, and a tan colored school uniform.

"Actually, I only know very little about him. I do, however, know that there is another transfer student and that he and I to start at the same time but it didn't work out that way. I would handle long-range attacks, he would focus on close-range. Our combined efforts were to back Koro Sensei into a corner. Except, our masters recalled the order for, well, reasons." Ritsu said in a serious tone.

"Yeah? And those were?" replied Hara as her and the rest of the class intently listened to Ritsu's every word.

"For one, my counterpart needed a few tweaks before being put into the field. Second, it was deemed I lack the capacity to support someone of his skill. Compared to what he's capable of, well, let's just say that I don't quite measure up. But going back to today's arrival, from what I've been told, not even my partner can hope to hold a candle to him." Ritsu said in a dead serious tone causing most of the class and Koro Sensei to start sweating.

'For her to say that when she blew off Koro Sensei's fingers. Whoa. What kind of monsters can these new guys be?' thought a blue haired boy named Nagisa Shiota as sweat dripped from his forehead.

Unlike most people in his school, Nagisa went by his first name, but that wasn't much of a problem. He was easily noticeable due to his petite-frame, blue hair, and blue eyes. He wore gray school pants, a white undershirt, a dark blue vest, and a hair band on each wrist. Unfortunately for him though, some would even mistake him for a girl due to his appearance. Especially since his blue hair was tied up in pigtails.

Just then, the door to the classroom opened to reveal an unexpected site. At the door stood two people. One was an older man with thick gray hair, and military clothes and the other was a small kid in tan school pants, black shoes, a white button up shirt, and a black vest.

However, the first thing they noticed about him was that he had spiky black hair and that it stood somewhat to the right side of his head and his spiky bangs. They also noticed black eyes and that he was even shorter than the two shortest people in their entire classroom. Which, of course, lead them to believe that he must've been even younger than them. Perhaps even an elementary school student.

What the students didn't notice was that while these two individuals opened the door, their teacher paled, liquified himself into a mercury-like slime, and hid in a far corner of the ceiling faster than anyone could see. Well, faster than almost anyone.

'So that's him. He doesn't seem that dangerous. But then again, looks can be deceiving. It's still strange though that I don't sense a strong ki from him. It feels like that of a normal human's if anything.' Gohan thought to himself as he looked at Koro Sensei hiding in the corner.

'No way! Did he see me move!?' Koro Sensei thought in panic while sweating profusely even after Gohan took his eyes off him to look at the class.

It was then that the class looked to where Koro Sensei was once standing only to notice him hiding in the corner in his liquified form. This earned quite a few criticisms from the class of how he could be scared so badly by an old man and a little kid to use his liquefy trick.

"My imagination just ran a little wild after Ritsu's story that's all. Nice to meet you two. May I help you?" said Koro Sensei as he dropped to the floor and reverted his body back to normal.

'No way! He sounds just like Krillin!' Gohan mused to himself happily as thoughts of his friend flooded his mind before feeling a little homesick.

"Yes, this boy here is named Son Gohan but he has clarified that he would prefer to be called by his given name, Gohan. As of today, Gohan will be joining your 'Assassination Classroom' as you call it." explained General Howser before putting his hand on Gohan's shoulder, told him goodbye for now, and left.

This made Koro Sensei pale once again as he realized this boy was indeed the boy from Ritsu's story.

"Oh wow. I didn't expect this new assassin to look so childlike and innocent." Nagisa said to a green haired girl beside him that wore cat ear shaped pigtails and had hazel eyes.

This girl was Kaede Kayano. She was the shortest person in the classroom before Gohan joined. Up until then, the only one that was close to her height was Nagisa. She, like many others in the class wore a gray school uniform.

Kaede was also small framed just like Nagisa. But whereas people teased Nagisa for looking like a girl, people teased her about her chest size, saying that she will be forever flat.

"Same. When I heard Ritsu's story, I imagined him being a monster almost like Koro Sensei or worse. It's kind of off-putting." responded the girl as she smiled awkwardly not knowing how to handle the situation.

"So, uh, welcome to Class 3-E Gohan. My name is Koro Sensei." the anxious teacher choked out as he tried to get ahold of himself. He had to be professional about this. Gohan was his student now. So, he stuck his hand out for Gohan to shake it.

Every cell in his body was screaming at him to run far away from this boy. If Ritsu and that other kid couldn't even hold a candle against him yet she was able to hurt him so easily, he had to be ready for anything at any given second.

Not only was it possible that Gohan had managed to watch him move but it was something similar to this when Karma Akabane managed to destroy his hand with strips of an anti-sensei knife taped to his hand.

'Did Gohan anticipate a handshake and is planning to do the same thing Karma did? Does he even know about anti-me weapons? Why can't I just calm down?' Koro Sensei internally panicked to himself.

However, all those thoughts came crashing down when as soon as his hand made contact with Gohan's all that happened was a normal handshake. No tricks or anything. Quickly coming out of his shock, Koro Sensei decided to attend to the next matter of business.

"Alright Gohan, we have two seats in the back of the classroom as we were told that you and one other student would be joining the class. You can take your pick of whichever one you want." announced the teacher causing Gohan to bow politely and thank him before walking towards the back of the room.

As he made his way though, he decided to sense the energies of the people around the empty seats so that he didn't sit next to any unpleasant people. He had the choice of sitting in between a boy with a neutral ki and boy with an angry ki or he could just sit beside the neutral boy.

Then, without a second thought, Gohan sat to the left of the neutral boy.

Gohan then looked at the neutral boy and noticed that he had a lean body, pale skin, short red hair, and goldish colored eyes. Gohan also noted that he wore gray school pants, a white button up shirt, and an open black jacket.

"Hi, I'm Gohan." Gohan said as he waved to the boy beside him.

"I'm Karma. Hey, I got a question for you. Are you really as dangerous as Ritsu said you are?" Karma question causing Gohan to become confused.

"Let me explain. We were told that out of all of us, you probably have the best chance at killing Koro Sensei. Is that true." explained Karma.

"Well, I'm not going to lie, as far as I can tell, I am the strongest one in the class, so yes. I'm probably even stronger than Koro Sensei but to be honest, I don't really want to kill him. I explained when I was offered to come here that I won't kill him unless I can't find any other possible way to keep him from destroying the world." Gohan told Karma and the class even as they stared at him in silence.

Little did they know, Mr. Karasuma was standing outside the classroom listening to the whole conversation. He wouldn't lie, even he was curious about the boy. He could be the solution to this whole thing after all.

"Alright. If you think you're stronger than the rest of us and even him..." Karma began while pointing his thumb at Koro Sensei, "then how about you prove it to us? At the end of the school day, you and Koro Sensei should have a little match to see who's really the strongest here."

"I can't do that Karma. It is against my agreement that I can harm a student." intervened Koro Sensei before things could get out of hand. That is, until Gohan spoke up.

"Actually, Sir, I was told before I came here that you are allowed to face off against me at any time because of how strong I am and I wouldn't mind having a friendly spar." Gohan stated making Koro Sensei pale and sweat. Gohan might really just be the death of him.

"It's settled then. The two of you will face off outside after school." Karma declared as Koro Sensei gulped in fear.

After the school day was officially over, all the students and teachers in Class 3-E exited the small building and gathered on the field where they had gym class.

Everyone had different ideas of what the outcome of this fight would be but almost nobody thought Gohan stood a chance alone.

"Hey, Kayano, do you think Gohan can really win?" Nagisa asked his green haired friend but also gaining the attention of Karma.

"I honestly don't know. According to Ritsu, Gohan has the best chance out of us at beating him though." responded Kaede with uncertainty as Karma approached the pair.

"I think he might just be able do it or at least come close. Did you see the way he carried himself? He's not intimidated by Koro Sensei at all. There's definitely something about him that we don't know." deduced Karma making his two friends look on in thought.

Just then, Koro Sensei zipped in the middle of the field with his usual smiling look as his tentacles swayed in anticipation.

"You seem better." Mr. Karasuma pointed out while a woman stood next to him.

This woman was the English teacher for Class 3-E and her name was Irina Jelavic. She was cruel, calculating, loudmouthed, rude, and arrogant. She had fair skin, light blue eyes, wavy blond hair, a curvy figure, and a large chest. Irina also wore heeled shoes, stockings, a white skirt with a black belt, and a form fitting white jacket with a black undershirt.

Unfortunately for Irina though, her students had come up with an... unsavory... nickname for her. She hated the nickname but she still cared for her students deep down. Even if she was a professional assassin.

"Yeah, what happened to you? You've seemed on edge all day ever since Gohan arrived but now you're calm." the English teacher pointed out.

Koro Sensei just looked at them for a moment while smiling before finally speaking up.

"Let's just say that a few laps around the Earth is a good way to clear one's mind and concience before their imminent death." Koro Sensei responded serenely as the wind gently blew around him and the class.

"He's really ready for Gohan to kill him, huh?" Karma rhetorically asked as the rest of the class just sweated awkwardly at their teacher's actions.

A few more minutes passed though as everyone began to grow impatient for the impending match. That is, until Gohan walked up to the class.

"Sorry for being late. I had to grab a bite to eat real quick. Nothing too big." Gohan laughed out while rubbing the back of his head.

"So, are you ready Koro Sensei?" Gohan asked while getting in his fighting stance.

This fighting stance was something which the gym teacher immediately picked up on though. He could easily tell that Gohan had complete mastery over this unusual stance. One thing was for sure though, he would definitely have to have a little one-on-one talk with the boy sometime soon but now was not the time.

"Indeed, I am Gohan. Indeed, I am." the teacher replied serenely as if waiting for Gohan to take the first move.

'I better not go full out just yet. I have no idea what he's capable of.' Gohan thought to himself while watching for any sudden movements from his teacher.

"Aren't you going to use any anti-me weapons?" Koro Sensei asked out of the blue thus ruining the intense mood.

"What's that?" wondered the demi saiyan equally as confused.

"They are specialized weapons developed by the military that are harmless to humans but deadly to me." Koro Sensei stated before rushing and grabbing an anti-sensei gun and blasting his hand off.

Gohan was initially shocked and was about to rush to his aid but stopped when he saw the tentacled hand regrow itself.

"I understand now. But I don't think I'll need it." Gohan smiled making the girls in his class smile at his innocence. They just wished the boys their age were more like that.

"Very well then. So, who will have the first move?" Koro Sensei asked as he readied himself for the impending battle.

"I'll let you have it." Gohan said while getting back into position.

This of course, caused the class to mutter amongst themselves as they thought Gohan had gone insane and bit off more than he could chew.

Then, without another word, Koro Sensei took off towards Gohan faster than the human eye could see.

Everything seemed to slow down for him. Even Gohan didn't seem to react to his speed.

'I must've imagined it earlier when I thought he saw me move in my liquified form. Alright then, I'll just grab him with my tentacles and this match will be over with.' Koro Sense gleefuly mused to himself.

However, just as his tentacles were about ensnare Gohan, the boy suddenly smiled and ducked leaving Koro Sensei wide open for an attack.

Koro Sensei closed his eyes in anticipation but only found that he had flown past Gohan and immediately stopped himself by placing his tentacles on the ground.

As for the other faculty members and the students, everything happened as fast as a blink of the eye. One second the two competitors are standing still and the next, there's a dust cloud and Gohan is standing in the same spot he was.

As the dust cleared, everyone could see that it was Koro Sensei who had created the dust.

"Did he miss?" one student spoke out as the rest of the class wondered the same thing.

"No..." replied Mr. Karasuma in a serious voice which made the class quiet down and continue watching.

'No way. He's fast!' thought the octopus with fear. He now realized that Gohan was no joke and that he would have to take this seriously if he wanted to win and hopefully see another day.

As for Gohan, he was having different thoughts.

'Ok, he wasn't that fast but he is definitely faster than a normal human. Unless he was just testing me, he's probably only as fast as my dad when he fought my uncle at best.' Gohan mused while staring down his opponent.

It was then that Gohan decided to take some initiative and blitzed to Koro Sensei. His teacher barely had the time to react before he received an uppercut to the chin that sent him flying vertically into the air.

He then jumped high into the air to surpass his teacher's height and hit him from above, sending him into the ground below.

When he hit the ground, Koro Sensei stayed still for a few nanoseconds as he thought he saw birds flying around his head. He then stood right back up and flew to Gohan to intercept him before he could descend since he would be vulnerable in the air.

What he didn't account for what was happened next. As he sped toward the demi saiyan, Gohan dodged by moving to his right. Such a thing should've been impossible. With the exception of people in aircraft and a few species of animals, he was the only one that was supposed to be able to fly!

In his shock though, Koro Sensei failed to notice the horizontal kick to the side that Gohan was about to land on him.

Then with a cry of pain, Koro Sensei was launched to the other side of the schoolyard. He landed in a small heap before he struggled to stand himself up again as the battle slowed to a visible pace once again.

Gohan then slowly approached his teacher. As he got closer though, Koro Sensei did nothing. It was beginning to concern him. Maybe he had used too much power in that last kick?

However, Koro Sensei wasn't out for the count just yet. As Gohan got closer, he inwardly smiled, looked Gohan in the eyes to get his attention, and said "You are a very strong opponent Gohan. I have to admit, I did underestimate you. However... you've let your guard down."

True to his word, Gohan actually did lower his guard since he was sure the battle was over. It was upon hearing his teacher's words that he noticed two tentacles around his ankles but not quite touching his skin.

Before he could react though, Koro Sensei squeezed as tight as he could and flew into the air. As he ascended, he spun in a clockwise motion in an effort to disorientate his student before he finally let Gohan go and sent him flying.

Gohan flew for about ten feet before he caught himself midair and looked at his teacher and caused his classmates to be surprised as they had not known he could fly.

"You caught me by surprise Koro Sensei, but it won't happen again!" Gohan praised his teacher only to hear him laughing superiorly as green stripes etched themselves onto his head.

Koro Sensei, feeling confident, rushed at Gohan's flying form while spreading his tentacles far and wide around Gohan giving him no room for escape.

"It's no use Gohan, I've got you trapped and I've made my tentacles sticky so, that even with your speed and strenght, you won't be able to escape." Koro Sensei declaired. However, Gohan merely smirked before crossing his arms across his chest to form an X.

Just as the tentacles were about to grasp Gohan in their sticky grip, Gohan flung his arms to his sides and screamed.

Gohan was immediately surrounded in a bright light that just seemed to grow larger and larger by the millisecond.

Thankfully, for Koro Sensei, he had just the way to save himself from whatever Gohan was planning. As his hands got disintegrated, he did something that Gohan would have never guessed.

When the light finally faded from Gohan's destructive attack, Gohan saw what seemed to be an empty sack that was once Koro Sensei laying on the hard ground.

However, he wasn't fooled by his teacher's trick, and rammed his elbow backwards causing a gasp of shock and pain from his teacher.

"How did you know where I was? Surely you were blinded by that attack you made? How did you know that wasn't me down there?" questioned Koro Sensei while grasping his stomach in pain.

"That's easy. I'm able to sense people's energies. Every living thing has a unique energy signature that can be sensed. I can even sense how strong a person is and what their intentions and moods are if I concentrate on someone hard enough." Gohan explained to his teacher.

"You know, I think I've actually heard of abilities similar to that in forms of literature." responded the octopus as he readied himself to continue the battle for what he presumed to be Gohan's attempt to assassinate him.

Noticing that Koro Sensei was readying himself once again, Gohan decided enough was enough.

"Well, I think that's enough sparring for now." Gohan smiled as he descended to the ground.

"Huh?" Koro Sensei asked with a blank face. Here he was preparing to fight to the end and his opponent just called it off. What?

"Yeah! I did say that was just a sparring match, right?" Gohan asked awkwardly while rubbing the back of his neck in embarrassment. This caused the rest of his class just to look at him like he was crazy. "Besides, I did say that I wouldn't kill you unless it was a last resort."

"That... That's correct. I'm sorry, Gohan, I thought you were saying that to lower my guard around you. I see now that I was wrong and that your words were genuine. Is there any way that you can forgive me?" asked the octopus as he put his hand on Gohan's shoulder and walked towards the rest of the class with him.

"Actually, you see, I need lots of food because of my metabolism, so when I was coming out here, I happened to smell some food in a fridge and helped myself to it. I hope that's not too big of a problem." Gohan said with some guilt. However, with what Koro Sensei said next, he felt much better.

"That's alright Gohan. I appreciate that you told me but I would like for you to ask next time before just eating it." Koro Sensei happily said. 'I see he is very mature for his age. Most boys his age would have never admitted to something like that.'

It was then that Gohan and Koro Sensei met up with the rest of Class 3-E. Koro Sensei told the rest of the class to save any questions for tomorrow though because it was time for everyone to go home. That and he didn't want Gohan to get too overwhelmed. It was only his first day after all.

Since Gohan, didn't have anywhere to stay though, he decided to give General Howser a visit at the base, tell him how things went, and see about staying there temporarily until he could find a place to stay.

Meanwhile, Koro Sensei was happily walking throughout the Class 3-E building. He had just finished cleaning up from his spar with Gohan and was about to check what he could get to eat out of the fridge.

"I hope Gohan didn't eat my dessert. I flew all the way to South America for it." the teacher mused to himself. As he opened the door though, he was greeted with a horrifying sight.

"He ate every last bit of food! That was a whole month's salary!" Koro Sensei cried out in shock before collapsing to the ground in despair.

Alright, that's it for this chapter! I really hope you enjoyed it because this was my first time ever writing a fight scene! So, make sure to give me your thoughts on it! Anyways, see you all next time!
