I don't own anything except for my OC's.
I'm sorry if you find any grammar mistakes. I'm still learning English because it's not my first language.
Words couldn't describe how tired and sleepy David was feeling as he proceeded to make his way towards his school building. He couldn't remember the last time when he was this tired when he was making his way up the mountain. It was probably during his first days in E Class when he was still getting used to the long walk up the mountain. He could only blame himself for this state, though. He shouldn't have stayed up this long watching a TV show with Ritsu. The weather which was quite rainy today wasn't making his journey to his school building any better.
The exchange student had his eyes set on his phone which he was holding in front of him as he was in the middle of having a message conversation with Samantha, which was mostly about him starting to watch Supernatural yesterday. He was telling her about this, because she was the one who recommended this show to him in the first place.
Of course, he cut the part with Ritsu off from his explanation, when he told her about this, because what was he supposed to tell her? That he was watching this show with a classmate of his that happened to be an AI?
Samantha Fairbanks: I'm glad to hear you decided to finally give this show a chance. You have no idea how happy this makes me.
David Miller: I'm glad to hear that it makes you happy :)
Samantha Fairbanks: What made you decide to watch the first episodes of this show? It took you a while to finally give it a shot.
David Miller: I just figured out it would be the best time to finally start it. After all, you didn't start watching too long to watch Breaking Bad, after I recommended it to you.
Samantha Fairbanks: How many episodes did you watched?
David Miller: Six.
Samantha Fairbanks: Six? Jeez, did you got any sleep last night?
David Miller: No and I feel like a dead body because of it.
Samantha Fairbanks: xD
Samantha Fairbanks: It reminds me of the time when all seven of us had a movie night at Brian's a few months before you left to Japan.
David Miller: I remember it too. We didn't end up getting any proper sleep and immediately regretted having this movie night the day after. We got some nice pictures to tease Brian and Jadis out of it, though.
Samantha Fairbanks: Yeah. Showing them the pictures of them cuddling each other as if they were cats reminded me of the times when they weren't together and teasing them was easier.
Samantha Fairbanks: Back to the topic of Supernatural, I guess you like the show so far since you watched six episodes in one sitting?
David Miller: Yes. I like it so far. It started off with a bang, with their mom and Sam's girlfriend getting burned alive by the same thing. It got me wondering what will happen in the next seasons.
Samantha Fairbanks: Trust me, what happened in the first episode is nothing compared to what these two poor bastards will go through in the entire show.
David Miller: Should I be afraid, then?
Samantha Fairbanks: Yes. A lot of "I hate this show" moments are ahead of you. I won't spoil anything to you, though, because I'm not that kind of person.
David Miller: Good. People who spoil things to the other people for their own amusement are just the worst.
Samantha Fairbanks: Exactly.
David looked up from his phone and looked ahead of him. He was only several steps away from reaching his destination. He will have to end the conversation with Samantha soon.
David Miller: I gotta go.
Samantha Fairbanks: Okay. Make sure to share your thoughts about Supernatural with me. I will gladly listen to what you have to say about it :)
David Miller: I will. This is what always do whenever we find something we both enjoy, right?
David Miller: Talk to you later, Sam. Tell the others I said hi. :)
Samantha Fairbanks: I will :)
David took his eyes off his phone and placed it in his right pocket where he usually put it after using it, no longer having the need to use it after finishing his conversation with Samantha. He proceeded to make his way up the mountain for the next few seconds and finally after what felt like an eternity to him an old looking building which he had gotten to know as his school building came into his view.
"I did it!" He shouted to no one but himself as he threw his hands into the air as if he just won a golden medal in olympics all by himself, only to collaps on the ground, feeling like he was about to fall asleep at any second.
The exchange student just proceeded to lay on the ground for the next few seconds, looking up at the sky, feeling how the rain drops were landing all over his body, soaking his uniform. He closed his eyes and opened them a second later, intending to get himself back on his feet. He stopped himself from doing so, when he saw two people standing over him. They must have stopped in front of him when he closed his eyes for a brief second. He instantly recognized those people as Isogai and Kataoka. His two classmates were looking down at him.
"Morning Isogai." He greeted Isogai as he shifted his gaze towards Kataoka and greeted her as well, "Morning to you too Kataoka."
"Morning to you too, David." Isogai greeted David in return, offering him a small welcoming smile as Kataoka nodded her head at David's greeting, "Do you need any help?"
"Yes." David nodded his head in confirmation the moment he heard Isogai's queston, "That would be greatly appreciated." Isogai nodded in return and reached his hand down towards David. The exchange student grabbed it and Isogai pulled him back on his feet. David smiled at Isogai in a grateful manner, "Thanks, Isogai."
"No problem." Isogai smiled back.
The three of them began walking towards the school building shorty after. The three students of E Class continued to make their way towards their school building in a comfortable silence as they were very close to the entrance at this point. Isogai and Kataoka couldn't help but wonder and worry why their classmate collapsed on the ground, though.
"David." The latter called out for the foreigner, breaking the silence that formed between them.
David looked at her, "Yes?"
"Why did you collaps on the ground?" She questioned what was on her and Isogai's mind, "Are you not feeling well?"
"No." David shook his head, before rubbing his eyes, "I'm just sleepy. I haven't gotten much sleep last night."
"Why?" Kataoka wanted to know. Isogai looked curious as well, "Did you have trouble falling asleep?"
"No. I stayed up all night watching a TV show." David explained as he braced himself for the lecture he was about to receive from Kataoka, knowing one was ahead of him the moment he told her the real reason why he didn't get much sleep last night.
"David." Kataoka's voice was stern, "Do you know you shouldn't have do this? Staying up all night watching a TV show and not getting any sleep is not healthy for someone our age."
"I know." David admitted, "I can only blame myself for it. I started watching this one TV show yesterday and I wasn't excepting that I will end up watching six episodes in one sitting. I didn't realize what hour it was until I looked at the clock on my laptop. I just lost the track of time."
"I hope you will make sure to keep the track of time the next time you'll be watching something on your laptop. You're going to need all the energy you need to keep up with Koro-sensei's classes." Kataoka said as Isogai stopped in front of the entrance to the school building once he reached it, "I doubt it will happen again soon, though." She eyed David's exhausted expression, "From what I see, I can see how much you regret staying up this long on the school day and I can tell that you've learned your lesson."
"Believe me, I did." David reassured her as Isogai opened the entrance to the school building, allowing all three of them to enter the said building, "The next time I will do something like this will be when I will be certain that I don't have to go to school or anywhere else the day after."
The first class was about to start and all the students of E Class were sitting on their seats in their classroom, waiting for Koro-sensei to arrive. David's face was lying flat on his desk as he was trying to stop himself from falling asleep and needless to say, his behaviour earned attention of some of his classmates who were seated around him.
"David." Nagisa called out for him, "Are you alright?"
David didn't lift his head up from the desk. He lifted up his left hand in the air and responded to Nagisa's question by giving him a thumbs up, "I'm fine, Nagisa. I'm just sleepy."
"Sleepy?" Kayano asked him from her seat, "Did you have trouble falling asleep last night?"
"No." David shook his head at Kayano's question.
"Does it have to do something with us watching a TV show until late night?" Ritsu asked from the back of the classroom, making some of her classmates turn around and look at her. David stayed silent and gave her a thumbs up as a way of confirmation. An apologetic expression formed on her face, "I'm sorry, David."
"Don't apologize." David said to the AI, not lifting his head up from his desk, "It's my fault for losing the track of time."
"I'm at fault here as well." Ritsu admitted, "I should have inform you about the late hour, before you found out about it by yourself."
"Hmm?" Karma titled his head to the side to look at Ritsu as he looked interested by the information he just received. Nakamura seemed interested in it as well. His lips twitched upwards, devilish smirk slowly forming on his lips, "You were watching a TV with David last night, Ritsu? Was there a particular reason why you wanted to watch it with him?"
"A particular reason?" Ritsu looked confused, "I just voiced my interest to him about TV shows and movies when I was accompaying him to his dorm complex. He offered to me that we could watch something together whenever we would have some free time. This what exactly what we ended up doing right after." Ritsu replied. She paused for a moment and placed her hand on her chin, tears building up in her eyes. It looked like she was about to cry. Her background changed as well. It became more rainy and foggy, "The start of the TV show we watched yesterday was so sad. Their mother was murdered when they were very young and now when they're older, their father has gone missing and Sam's beloved one was killed by the same monster that killed his mom."
"You were accompaying him on his way to his dorm complex?" Nakamura asked as she held a similiar grin to Karma's on her face, "Why? Was there a particular reason why?"
"I just happened to be on his phone when he was on his way to his dorm complex." Ritsu replied as she looked up at Nakamura, her background changing into the usual sunny one, "We were planning to part ways as soon as we would reach David's dorm complex, but our plans changed."
The conversation ended shorty after it started as the door to the classroom was slid open and Koro-sensei walked in. Most of his students shifted their attention towards him the moment he entered the classroom and immediately noticed something strange about their teacher. His head was larger. Much larger than it was the other times they saw him.
"All right, class. Time for homeroom." Koro-sensei said , sounding a bit strained, shorty after he made his way into the classroom as his students had their eyes on him, "Please, take your seats."
"...He seems larger than life today." Nagisa stated.
"Koro-sensei." Ritsu called out for her teacher, looking to be suprised by how large Koro-sensei's head was as much as her classmates, "Can you explain why your heard is approximately 33 percent bigger?"
"Ah." Koro-sensei began as he squeezed his head, intending to drain it, "It's soaked up lots of moisture thanks to the high humidity."
Koro-sensei's weakness number 13: Prone to dampness.
"What are you?" Muramatsu exclaimed as Koro-sensei leaked the water into a bucket after squeezing his head, "Uncooked rice?"
When Koro-sensei finished leaking the water into the bucket and the size of his head returned to normal, he said, the tone of his voice returning to his usual tone, "Now, then. I believe Karasuma-sensei told you about another transfer student coming."
"Yeah." Maehara responded, "Probably another assassin."
"I got into a spot of bother taking Ritsu-san too lightly last time." Koro-sensei stated as he pointed one of his tentacles at Ritsu, making her classmate look at her, "I won't make that mistake again." Ritsu giggled as Koro-sensei rubbed his tentacles together, "In any case, it'll be nice for you to have a new classmate."
Hara turned around to look at Ritsu, "Hey, Ritsu, have you heard anything? You know as a fellow transfer assassin?"
"Yes, a little." Ritsu replied as her classmates turned around and looked at her curiously. David's face remained on his desk though he listened to everything as carefully as his classmates, "Originally, he and I were to be introduced together. I would handle long range attacks, and he close-range combat. Together we'd drive Koro-sensei into a corner. However, those orders were cancelled for two reasons."
"Really?" Hara asked out of curiosity, "What were they?"
"Firstly, his adjustments took longer than excepted." Ritsu began, "And secondly, I lack capability to provide him support. As an assassin, I am overwhelmingly inferior to him."
Koro-sensei looked down in fear as Ritsu's classmates continue to stare at her. David gulped nervously as he listened to Ritsu had to say to him and the rest, an image of his new classmate slowly forming in his head. If Ritsu who manage to blew off Koro-sensei's finger on her first day considered herself to be overwhelmingly inferior to him, then what was this person going to be?
It was when the sound of someone sliding the door open rang through everyone's ears. They turned to the source of the noise and saw a man wearing white robes and a mask over his face. Everyone looked at this stranger as his eyes gleamed red through his mask at them. Everyone could easily say that it was an adult, because he was far too tall to be a student.
"What's with the outfit?" Kataoka asked, looking at the unknown man.
"Is that the new student?" Okano asked shorty after.
The unknown man held out two fingers and twisted his hand, making a white dove appear on his hand. The class gasped in surprise as they were not excepting this man to introduce himself like this, making the said man laugh.
"Sorry. Didn't mean to frighten you." He said as he placed the dove aside, "I'm not the new student. I'm his guardian." He took a step forward and introduced himself, "You can call me "Shiro" meaning "white"."
"Some guy all in white comes in doing tricks?" Kayano said with a weirded out smile as Nagisa smiled slightly, "That'd spook anyone!"
"Maybe not Koro-sensei, but..." Nagisa shifted his gaze from Shiro towards Koro-sensei. His words died in his throat when he saw Koro-sensei in the corner of the ceiling, hanging onto it in his liquid state.
"Koro-sensei!" Maehara shouted, "You scaredy cat!"
"He's spooked enough to use his liquefy trick!" Okajima added.
Koro-sensei's weakness number 14: Falls for rumours.
"Well! Ritsu was telling all those scary stories!" Koro-sensei exclaimed sheepishly. He poured himself down the ceiling and formed himself into his usual form in front of Shiro, "N-Nice to meet you, Shiro. Where is our new student?"
"It's a pleasure Koro-sensei." Shiro replied, "He's a rather unique child, in personality and otherwise." He began making his way to the front of the classroom and Karasuma looked through the window into the classroom, "I'll introduce him myself."
"He's awfully evasive." Nagisa thought to himself as he and his classmates watched Shiro approached Koro-sensei. Shiro turned to look down at the blue haired student as Nagisa looked at him in confusion.
"Yes?" Koro-sensei asked.
"Oh, just." Shiro shifted his gaze from Nagisa towards Koro-sensei, "You've got good kids here. I'm sure he'll fit right in. Now to introduce him." He turned around to look at the entrance to the classrom, "Hey, Itona! Come on in!"
The wall in the back of the classroom, the remains of it flying anywhere. A short white haired boy walked out of the cloud of smoke and dust which formed around the area of the back wall and sat down on his seat between Karma and Terasaka.
"I won." The boy said, staring ahead of himself, a crazed look in his yellow eyes, "I proved that I'm stronger than the classroom wall."
"Come on!" E Class shouted at their new classmate, their eyes wide, "Use doors next time!"
David was the only exception. His head shot up from his desk as he declared loudly, "I'm not sleepy anymore!"
"That's all that matters." Itona said as if he didn't even hear what his new classmates just said to him, making them sweatdrop, "That's all."
"We've got us another handful!" Maehara stated, looking at his new classmate.
"Even Koro-sensei doesn't know how to react!'' Nagisa said, looking at Koro-sensei. The octopus had an unreadable expression on his face, as if he didn't knew how to react to what just happened.
"'He's not smiling... not serious..." Sugino stated, eyeing the look Koro-sensei had on his face.
"I don't even know how to call this expression." David stated.
"This is Horibe Itona." Shiro introduced Itona to the students, "Please call him Itona."
"Say, Itona." Karma called out for Itona, leaning closer towards him, "Something's been bugging me." He looked over his shoulder at the hole in the back wall of the classroom, "You came in from outside? Empty handed? It's raining buckets out there and yet there's not a drop of it on you."
Itona titled his head towards Karma before looking around his surroundings, mostly eyeing his classmates who had their eyes on him. He got up from his seat and approached Karma's desk.
"You're probably the strongest one in this class." He said as he gently placed his hand on Karma's head. He leaned down towards Karma and gently ran his fingers through his red hair, "But, don't fret. I have no interest in killing those weaker than me." He removed his hand from Karma's head and began making his way towards the front of the classroom, "The ones I do want to kill are those who could be stronger than me." He stopped in front of Koro-sensei who was happily feasting on the red bean jelly bar, "And in this classroom, Koro-sensei... That's you."
Koro-sensei swallowed his candy bar and glanced at Itona, grinning at the threat he just received from him, "When you say strong and weak do you refer to fighting ability, Itona? In terms of strenght, you and I are worlds apart."
"We're closer than you think." Itona said as he reached into his uniform and pulled out his own red bean jelly bar. He took a few steps towards Koro-sensei, now standing inches away from him. He looked up at him, "We're brothers by blood."
"Huh!?" The students exclaimed in shock, looking at Koro-sensei and Itona in white widened eyes, "Bro-Brothers?!"
Itona ripped off the packaging of his red bean jelly bar with his mouth, completely ignoring the way how his classmates reacted to it. He pointed his candy bar at the octopus, "The loser dies, Brother." Koro-sensei just stared at him in stunned silence, "Siblings have no need for cheap tricks." He turned away from Koro-sensei and started walking towards the door. Shiro was already waiting for him in the hallway, "I will kill you and prove my strength. We face off after school, in this classroom."
It was the last thing he said before slamming the door, leaving his classmates in a stunned silence. The entire classroom was engulfed by a complete silence right after he exited it. The silence didn't last long, though. The students immediately got up from their seats and began asking Koro-sensei questions about Itona who was apparently his brother.
"Now hang on Koro-sensei! What's this brother stuff?!"
"Humans and octopus are nothing alike!"
"I haven't the foggiest!" Koro-sensei replied nervously as he raised his tentacles in the air an attempt to calm his students down, "I was born and raised an only child! When I asked my folks for a little brother, things got really awkward!"
"Wait!" Maehara exclaimed, "You have parents!?"
The lunch time has come and the students of E Class were sitting in their classroom. It was still raining outside and it seemed like it was not going to stop soon. Everyone were looking at Itona who had a large amount of all kinds of junk food on his desk. This amount of junk food could have only matched Koro-sensei's hunger for it.
"He's putting that candy away like nobody's business." Maehara stated as Itona took a bite of his chocolate bar, "He's got Koro-sensei's sweet tooth, all right."
"Not to mention his unreadable expression." Isogai added.
"That brothers thing sure has everyone comparing the two of us." Koro-sensei thought to himself as he lowered his chocolate bar. He reached into his desk and began searching through it for something, "Now, I'm all angsty. I'll cheer myself up by looking at the girly magazine I bought today." A blush appeared on his face for a brief second as he pulled out a magazine from his desk, "Ah, now this is for grown-up tastes!"
He quickly stopped what he was doing when he noticed Itona reading the same magazine.
"They even like the same big boobs!" Okajima shouted as he got up from his desk and clenched his fist, "His crebility just skyrocketed!"
Nagisa deadpanned, looking at Okajima, "You think so Okajima?"
"Oh, yeah!" Okajima replied as he turned around to look at Nagisa. He pulled out the same magazine Itona and Koro-sensei were reading, "All boob lovers are brothers!"
David shook his head, thinking to himself, "This is getting out of hand..."
Nagisa sweatdropped at how stupid this was starting to get, "...Now there's three of them?"
"If really are brothers..." Kayano began, "Then why wouldn't Koro-sensei know."
"Hmm." Fuwa hummed as she placed her finger on her cheek, thinking of an answer, "I bet it went like this..."
For the new few moments she proceeded to tell her classmates the story of how Koro-sensei and Itona could have been separated from each other. Her classmates quickly took her story for nothing but fiction, though, because the story sounded like something straight out of an anime or a manga. The story was about two brothers who were forced to flee from their castle after it found itself under a siege and were separated from each other during their departure.
"And once they grew up, they began their destined battle without realizing they were brothers!" Fuwa cheered once she finished her story.
"Nice origin story Fuwa." David smiled at Fuwa, looking at the said girl in amusement, "It still needs some more work, though. There are a few things you forgot to mention."
"Yeah." Kayano agreed, "Like how Itona is a human."
"Um..." Fuwa quickly thought of a reason, "Mutation?"
"You haven't explained the core issue here!" Kayano pointed out.
"You gotta did deeper on your characters, Fuwa!" Hara added, "And as David has already mentioned, your plot needs a lot more work!"
Nagisa looked over his shoulder as his classmates continued to argue with Fuwa about the origin story she just came up with. Itona looked up from his magazine at the argument going on between his classmates, before going back to reading it.
The school bell rung which meant the end of class. The fight between Koro-sensei and Itona was about to begin. The classroom had been pulled apart, because of it. The desk were formed into a square formation around the room. Koro-sensei and Itona were facing each other, standing on the opposite ends of the classroom. The students of E Class, along with Karasuma and Bitch-sensei were standing outside of the square.
Itona grabbed his upper clothes and threw them into the air, leaving himself only in a red sleeveless shirt. Koro-sensei just looked at him nervously.
"They arranged their desks into a ring?" Bitch-sensei asked, looking around the classroom.
"Yep." Karasuma replied, "Like a real match. I've never heard of anyone going about an assassination like this."
"You must be sick of plain old assassination, Koro-sensei." Shiro stated, standing behind Itona, "Shall we set a rule, then? How about "Stepping out of the ring means instant death". What do you think?"
"The hell?" Sugino said, "As if the loser would ever keep their end of the bargain."
"He will." Karma said, much to Sugino's suprise, as he was standing between him and David, "For him to break a rule we all witnessed would damage our trust in him as a teacher. That kind of restriction works especially well with this guy."
David leaned against the wall and folded his arms, letting out a yawn as he did so, "It's actually a pretty clever way of handicapping Koro-sensei."
"All right." Koro-sensei looked up at Itona and Shiro, "I accept your rule. However, Itona, hurting the spectators will also result in a loss."
"Very well." Shiro accepted the rule. Itona did as well, nodding his head in response to Koro-sensei's words, "Start on my signal." He raised his hand in the air, "Assassination." The students all watched it, waiting for the fight to begin. He lowered it a second later, "Begin!"
Koro-sensei's left tentacle arm was cut off the moment Shiro lowered his hand. Everyone felt how their eyes widened in shock, not believing what they were seeing. Itona's hair was made of tentacles. A few white tentacles were sticking out of his head, waving around crazily.
"It can't be..." Koro-sensei's voice was filled with disbelief. He kept his smile on his face, even though he was shocked as much as his fellow teachers and students were, "...Tentacles."
"Itona's hair..." Nagisa whispered to himself in shock as his classmates watched everything in stunned silence, "Is tentacles."
"...He hit the rain drops away with his tentacles." David's sleep deprived eyes were widened in shock as he came to a realization to why Itona was able to walk in the rain without getting himself soaked in the rain drops.
"So." Karma said as he realized it as well, "That's how he stayed dry empty handed in that rain."
"Where?" Koro-sensei's voice was dark as he growled out. His entire body turned black, his teeth sharpening, his eyes glowing red, "Where did you get those tentacles?"
"We're not obligated to tell you that, Koro-sensei." Shiro said, not paying attention to how angry Koro-sensei looked like, "But this ought to have convinced you. You have different parents and different upbringings, but you are nonetheless brothers." He set his eyes on Koro-sensei's angered face. Koro-sensei just continued to stare at him with completely red eyes, "My, what a scary face you're making. Did you perharps remember something unpleasant?"
"It would appear that you and I will need to have a little talk." Koro-sensei growled in a completely serious tone as his left arm regenerated.
Shiro raised his left hand in the air, showing off his wrist, "Unfortunely, you'll be dead by then." A violet light shined from the item on his wrist. Koro-sensei gasped once the light shined on him, "Exposure to this pressure ray at close range triggers dilatant behavior in your cells." Itona leaped himself towards Koro-sensei and begun his strike. Smoke engulfed the makeshift ring as Koro-sensei screamed from Itona's attacks. Shiro gave a thumbs down as he continued, "Your whole body stiffens instantly. We know everything. All of your weak points."
"Did he get him?" Muramatsu asked as he and his classmates continued to watch the clash between Koro-sensei and Itona from their spots.
"No." Terasaka replied as he looked up at the ceiling, "Look up!"
Koro-sensei was on the ceiling just like Terasaka said. The octopus was hanging from the rafters of the roof. He was panting loudly from exhaustion as sweat was going down his face, looking at what was happening below him in fear.
"You've shed your skin?" Shiro spoke again, "That's right. You did have that trick up your sleeve." Itona pushed himself into walk towards Koro-sensei and started approaching him, "However, Koro-sensei, we also know the downside of that process."
Itona looked up at Koro-sensei and attacked him once again by shoving his white tentacles towards him. Koro-sensei shrieked as he speeded away from his spot the ceiling to avoid Itona's strike. He began moving across the entire classroom as Itona continued to attack him, not giving him a single second to rest as his tentacles were attacking Koro-sensei each time he set himself on the floor.
"Moltings expends more energy than one would except." Shiro stated, "Therefore, the speed you're so proud of drops immediately afterward."
Koro-sensei's weakness number 15: Vulnerable after molting.
"And you've grown back the arm that Itona took in his first suprise attack." Shiro continued as Itona continued to attack Koro-sensei with his tentacles, shoving them rapidly his way, making the octopus move towards another spot in the classroom in order to avoid getting hit by them, "That used up quite a bit of stamina as well."
Koro-sensei's weakness number 16: Vulnerable after regeneration.
"By my calculations, you should be evenly matched physically around now." Shiro continued to speak, his eyes glowing through his mask, "Moreover, use of tentacles depends greatly on one's mental state."
Koro-sensei's weakness number 2: Loses his composure rather easily.
"And when one considers the shock of being injured by an unexcepted tentacle." Shiro said as Koro-sensei barely dodged Itona's attack after he was attacked by him with a massive speed, "It's obvious who is in the lead now." He raised his left hand in the air and pointed it forward, showing off his wrist again, "Furthermore, he has the support of his devoted guardian."
Koro-sensei's weakness number 17: Hardens upon exposure to a special beam.
He flashed the purple light at Koro-sensei again as Itona jumped into the air. It looked like he was preparing himself for one final strike. He spiraled down towards Koro-sensei. The octopus dodged it, but it costed him something. It costed him two of his legs to be exact. His students gasped once they saw how his legs collided with the floor after they were separated from his body.
Koro-sensei fell on his knees, panting loudly as Shiro chuckled at the sight, "Now, you'll grow back your legs too. That will drop your stamina even further, making you easier to kill."
"What a relief." Itona spoke for the first time since the fight between him and Koro-sensei started. He walked over to Koro-sensei, causing the octopus to look up at him, "Turns out I'm stronger than you, brother."
David leaned his head forward, not believing what was happening in front of him. Koro-sensei actually backed away into a corner, because of Itona. He actually managed to achieve something no one has ever achieved before when it came to assassinating Koro-sensei. The white haired boy could actually end up being the one who kills Koro-sensei.
Even though, Itona came this close to killing Koro-sensei, the exchange student couldn't help but feel a little disappointed. He didn't even know why he was feeling this way. He looked around his classmates and set his eyes on Nagisa. His blue haired friend was looking down at his Anti-Sensei knife in a saddened. He looked to be feeling the same way as he did.
It was when David came to a realization to why he was feeling disappointed by how the fight between Itona and Koro-sensei was turning out so far. Itona and Shiro already knew all of the weaknesses of Koro-sensei and were using them to their advantage, showing all of them off to him and his classmates one by one. He sighed internally. He and his classmates wanted to discover those weaknesses by themselves. They wanted to be the ones who would end up killing Koro-sensei.
David knew it was selfish of him to think like that. After all, saving the world from sharing the moon's fate was important, but the feeling of disappointment couldn't leave his body. After all, it was he and his classmates who were assigned to assassinate Koro-sensei and they constantly tried different ways to kill him.
Koro-sensei's legs regenerated and Shiro was quick to make a comment about it, "Your legs have regenerated, I see. Now, can you withstand the next onslaught?"
"This is the first time anyone's pressed me this hard." Koro-sensei took a few deep breaths and looked up at Itona and Shiro, "At first glance, it seemed like a straightforward face-off." He rubbed his tentacles together as if he was cracking his knuckles, "But it's all been so carefully calculated. There's a lot I'd like to ask you two but I won't get a chance unless I win first."
"You still think you can win?" Shiro asked, suprised, "The bluster of a cornered octopus, no more."
"There is one thing you forgot to take into account, Shiro." Koro-sensei pointed out.
"There is not." Shiro disagreed with Koro-sensei's statement, "My methods are impeccable. Kill him."
Itona's response to his order was immediate. The white haired boy jumped high into the air, readying himself for one final strike. He brought all of his tentacles down on Koro-sensei. The students gasped as the bits of mucus began flying in the air. The mucus wasn't Koro-sensei's, though. It was Itona's. The tentacles wielding teen glanced at his tentacles and saw that they were damaged.
"What's this?" Koro-sensei asked mockingly, with a tissue in his hand, "You seem to have stepped on something."
His entire face turned white as his students looked down to see a few Anti-Sensei knives laying on the floor. Nagisa gasped in suprise once he felt that something missing from his grasp. He looked down at his hands and noticed that his Anti-Sensei knife was missing. Koro-sensei must have taken it away from him at some point of the fight between him and Itona.
Itona backed away from Koro-sensei in shock as Koro-sensei's husk fell down and landed on top of him. Using his speed, Koro-sensei made his way to him and tied up his newest student in it, "If our tentacles are the same, then these anti-teacher knives should work the same too and the loss of a tentacle unnerves us both." He picked up the hush like it was a bag and looked at the window on his left. He threw the husk with Itona wrapped in it towards the window, "But I'm a little more seasoned than you."
His students watched with widened eyes as Itona collided with the window, causing it burst into pieces. Itona flied through the window and landed on the ground, sliding across it for a second.
Koro-sensei made his way to the destroyed window and continued, "You should be unharmed, wrapped in my old skin like that, but your feet are outside the ring." Itona got the hush off of him, looking up at Koro-sensei as green stripes appeared around Koro-sensei's head, "I win. As per the rules, that means you die. You can't kill me anymore."
This information angered Itona. He glared at his teacher, gritting his teeth.
"If you want to live, stay with the other students of this class." Koro-sensei continued, "And learn something that can't be measured just by crunching numbers, the difference experience makes. I've lived far longer than you and come to know a little more. I became a teacher, because I wanted to pass that on you all." His students watched his speak to Itona with proud expressions on their faces, "If you don't take my experience from me in this classroom, you'll never be able to beat me."
"I won't?" Itona whispered angrily, his eyes closed. He opened them a second later. His eyes turned red, with some sort of black and white energy going inside of them, "I'm weak?!"
"This isn't good." Shiro stated, knowing where it was going, "Itona absolutely despises studying and lecturing a child who hates to study could result in genocide!"
Koro-sensei watched through the broken window how new tentacles grew out of Itona's head, but this time, the tentacles were completely different. All of the tentacles that just grew out of Itona's head were black. He began swinging them around violently from his spot outside of the school building as his classmates watched everything in shock.
"What the hell?" David whispered to himself. Itona had black tentacles? Weren't they white just a few moments ago? This change could mean only one thing. Koro-sensei's words pissed Itona beyond words.
"Black tentacles?!" Nakamura exclaimed in suprise.
"Oh crap!" Maehara screamed, "He's gone off the deep end!"
"I'm strong." Itona said to himself angrily, "These tentacles made me stronger than all the rest. All the rest!"
Koro-sensei backed away from the window as Itona leaped into the air. He jumped through the broken window and shoved himself towards Koro-sensei who continued to back away from him. He never reached his target, though. A dart came flying from behind Koro-sensei and hit him in the neck, making him fall on the floor, unconscious.
"My apologies, Koro-sensei." Shiro spoke up, a small dart gun sticking out from underneath his hand and up his sleeve, "It seems this boy wasn't yet mentally prepared for school." He walked past Koro-sensei and walked over to unconscious Itona. He picked him up from the floor and placed him over his shoulder, "I know it's his first day and all, but he'll be taking a little break."
"Wait!" Koro-sensei exclaimed, making Shiro stop dead in his tracks, "I can't just let that student go! I'm his teacher! I shall look after him until he graduates! And, Mr. Shiro, I have so very much to ask you."
"Sorry, but no." Shiro replied as he pushed himself into walk again, walking past Koro-sensei, "We're leaving. Or would you stop us by force?"
Koro-sensei turned around to look at him and placed his tentacle on Shiro's shoulder, intending to stop him from leaving the classroom with Itona. His tentacle exploded the moment it collided with Shiro's shoulder. He moved his destroyed tentacle away from Shiro's shoulder and stared down at it.
"Anti-teacher fibers." Shiro explained, his back facing Koro-sensei, "You literally cannot touch me. Don't worry. He'll be back before long. After all, March is just around the corner. I'll take the task of tutoring him at home."
It was the last thing he said to Koro-sensei, before walking out of the classroom with Itona on his shoulder. The octopus watched him leave with his newest student on his shoulder through the broken window, until Shiro and Itona disappeared from his view.
When the class started to put desks back together, Koro-sensei was sitting at his desk. His head was in his hands. The octopus was crying, muttering how embarrased he was to himself.
"Oh, how mortifying!" He said to himself.
"What's with Koro-sensei?" Kataoka asked as she and her classmates were putting the desk back in their positions in the classroom.
"Dunno." Okano replied, standing next to her, "He's been like that for a while now."
"I'm ashamed to have been involved in such a serious development!" Koro-sensei explained to his students why he was behaving the way he did right now, "I'm far more suited to comic relief!"
"You sure got good and mad." Hazama had her eyes set on Koro-sensei as she walked past his desk, "Where did you get those tentacles."
Koro-sensei screamed, with a bit of a pink blush on his face, "Oh, please! Don't say that Hazama! Just hearing those words again makes me want to run for the hills!" His students gathered around his desk as he put his face in his hands, shaking his head, "I'm the evasive airhead type! That's my selling point! Showing my serious side will ruin my characterization!"
Koro-sensei's weakness number 18: Gets embarrassed in the aftermath of serious scene.
Sugino sighed, "It ticks me off tha you're deliberately managing your character."
"Still, that was quite a suprise." Bitch-sensei stated, her arms folded, "Who'd have thought that Itona boy would have tentacles?"
"C'mon, Koro-sensei." Isogai said, "Tell us how are you linked to those two."
"You've always dodged questions about your true form." Rinka pointed out.
David yawned into his hand. God, he will go to sleep right after he will return to his dorm room "You can't hide it anymore from us, Koro-sensei. After all, we're your students, and we should know the truth, especially after everything that happened today with Shiro and Itona."
"...Then I suppose I'll have to tell you the truth." Koro-sensei said after a moment of listening to what his students had to say to him, "The truth it..." He pointed at himself dramatically, "I'm an artifical lifeform!"
The entire classroom was silent for a moment. Everyone looked at Koro-sensei with completely blank faces, knowing of this face long before his declaration of what he truly was.
"...Well, duh." Okano broke the answer that formed in the classroom.
"What kind of reaction is that!?" Koro-sensei asked everyone in the classroom after seeing the way they reacted to his revelation, "Wasn't it a shocking revelation?!"
"It was quite obvious to everyone long before you told us about it, sir." David stated, looking at Koro-sensei as if he just said the most obvious thing in the world.
"No natural-born octopus can move at Mach 20!" Okajima pointed out.
"And if you're not an alien, that's about the only explanation left." Hara continued.
"Plus, if Itona said he was your younger brother." Kataoka continued, "He must've been created after you were."
"They're too sharp for me!" Koro-sensei screamed, his expression being the one of shock mixed with pride, "What frigtening children!"
"We want to know what happened after that, Koro-sensei." Nagisa explained to Koro-sensei what he and his classmates wanted to learn about their teacher, "Why did you get so angry when you saw Itona's tentacles? Why were you created, and why did you decided to come here?"
Koro-sensei was silent for a brief moment, his gaze set on the blue haired boy. He responded to his questions after a moment, waving his tentacle back and forth, his tone more serious than his usual one, "Sorry, but I'm afraid there's no point in telling you that now. If I destroy the Earth, everything you want to know will be as dust in the wind. On the other hand, if you save Earth, you'll have plenty of opportunities to learn the truth. If you want to know more, you realize there's only one thing to do: Kill me. Assassin and target. Those are the ties that bind us together. If you're looking for answers in me, you can only ask them through assassination. If there are no questions, we're doe for the day"
The students took a cautious step away from Koro-sensei, because of how much more serious his tone was from his usual one which he used everyday when he spoke to them. They all watched with wide eyes how he turned away from them and made his way to the exit from the classrom.
"See you tomorrow.'' He said as he slided the door open. He burried his face in his hands, going back to being embarrassed as he was a few moments ago, "Oh, how mortifying!"
Everyone sweatdropped at the sudden change of behaviour in Koro-sensei. It was the last thing they heard from him, before he walked out of the classroom, leaving them alone with their thoughts.
Karasuma was standing outside of the school building, talking on his phone with someone, informing the person on the other side of the phone about everything that happened today.
"...Yes, the students are unhurt." He said, "Make preparations for repairs."
"Karasuma-sensei!" His students called out for him, causing him to title his head to the side to look at them.
"What brings all of you here?" Karasuma asked, now looking at his students. All of them, "Quite, the crowd I see."
"Um." Isogai began, "Can you teach us more assassination skills?"
Karasuma's eyes slightly widened in suprise, "More than you already know?"
"We always figured somebody would wind up killing Koro-sensei." Yada said, "So we didn't take it seriously ourselves."
"Yeah." Maehara continued, "But when we saw Itona, we realized. We don't want it to be just anyone. We want to kill him ourselves."
"If they bring in another tough assassin." David continued from where Maehara left off, he and his classmates looking at Karasuma with determined expressions on their faces. "We'll lose the track of what all our hard work has been for."
"So, we want to kill our teacher the best we can in time we have left." Kataoka said, her hand resting on her heart.
Isoga raised his clenched hand into the air as he finished, "We want to kill him and find the answers ourselves."
"What a change in attitude. Excellent." Karasuma thought to himself as he smirked once he saw the determination in his students eyes., "All right. Interested students can stay after class for extra training. It won't be easy."
"Yes, sir!" His students chorused in response.
Karasuma looked at them with an evil look on his face as he pointed upwards at the line hanging from the tree branch above him, "Let's start with some climbing on our new rope!
"That's rough!" Most of E Class shouted as David bit his bottom lip, knowing how much exhausted he was going to be by the time this day would be over. At least he won't have trouble falling asleep today...
Hope it wasn't that bad. See you in another chapter.
