This, my friends, is the end of the first arc. Thank Koro-sensei, Merlin, and Zoldyck that it's finally over!
And with that out of the way, onto the story!
I do not own Harry Potter or Assassination Classroom.
They finally made it to the school. Koro-sensei was standing there, as though he'd been waiting for their arrival.
"Koro-sensei!"
They all ran over to him.
"Koro-sensei!" Kurahashi began, "Please, you need to get out of here. You can take us as hostages if you want to."
There were nods of agreement.
Koro-sensei shook his head. Seeming to accept that his time was here.
"Even if I did escape…you can't expect the nations of the world to leave a creature like me alone. That shield is completely anti me. And the laser…it could probably destroy me even in my absolute defense form."
They were all sad. Harry felt sad too. He'd come to really care for Koro-sensei…
The whole scenario had been so strange. So bizarre. Being taught by a yellow octopus like creature…finding out he was actually smart, being turned into an assassin. Hired to kill his teacher…
It almost made him want to laugh.
Hadn't he known this was coming?
"This assassination is a combination of all the world's wisdom and knowledge. So perfect…surpassing even my own abilities. I respect that. I am honoured to have been its target."
"But then…all our hard work getting here…that was all a waste?" Yada whispered.
"Is anything ever really a waste, Yada-chan?" Koro-sensei patted her head comfortingly, "You went all the way to space to find out the probability of my exploding was less than one percent. That brought the light back to a darkly sinking E-Class and the month that followed was short…but very sweet. The process…your hearts, that's what's important." He put a tentacle over his own heart, "You used every last bit you earned to save me. As a teacher, there can be no greater happiness."
There was some retaliation. Anger. But Koro-sensei responded in turn,
"As you go through life, the mighty current of society is bound to get in your way, and there will certainly be times when things don't go as you hoped. When this happens, do not look to society for a cause. Do not renounce society. Frankly, you'd be wasting your time. Instead, just say 'that's life.'" He shrugged with his tentacles, "And muddle your way through with frustration. Once you're passed it, consider: if society's swift current is tossing you around, how should you be swimming there in its midst? You should have learned how here, in E-Class. In this assassination classroom. You don't always have to stand and face it head on. You can run and you can hide. If it's not against the rules, you can try a sneak attack. You can use unconventional methods. Stay determined, not discouraged or impatient. And with repeated trial and error, you're bound to reach a splendid outcome eventually. That's because each and every one of you…is a top tier assassin."
Of all things…Nakamura had brought a cake.
This was the anniversary of the moon exploding. The day Miss Yukimura had decided was Koro-sensei's birthday.
She put a candle in the cake…and they sung Happy Birthday.
Before he could blow out the candle though…
Boom!
Something landed in the cake. A black shadow-like spear.
They all turned suddenly.
"Happy Birthday." It was…Shiro. Or the scientist guy, whatever.
Harry had tensed up automatically.
"Let me give you the gift of the worlds cruelest death."
The shadow thing with tentacles looked directly over at Harry. They all seemed to notice that all eyes were on him.
"You know who I am…don't you?" He spoke in a strange, glitchy voice.
It gave Harry the shivers. But…there was something familiar sounding under that glitchyness.
"Why don't I introduce you to your students too?" The man smirked, "He is the man who stole the name of 'The Reaper' from that octopus."
"You." Harry whispered.
"Eh?" Kaede looked at him, "You know him, Harry?"
Harry nodded,
"He tried to kill me before…I beat him. Barely." He whispered.
"Well," Shiro grinned, "As of today, he's the new Koro-sensei."
The monster with the black, skull-like face stared into Koro-sensei.
"You were my first student and I…" Koro-sensei spoke, "I wasn't seeing you."
A student? Harry wondered. That made a lot of sense in a strange way…
The large creature jumped into the air, flipped and landed on the roof of the school building.
"He has all the modifications and abilities Koro-sensei has. The only difference is that he begged for them. Completely unlike the botched Itona or my little sister over there."
"Die!" The monster jumped down on Koro-sensei.
The strike was so powerful, it sent everything in the surroundings flying. Including the students.
He was explaining this so calmly, Harry thought. His eyes traveled over to the monster and Koro-sensei. He tried to follow their movements…it was so fast though!
This creature the Reaper had become…could reach Mach forty. That was double the speed of Koro-sensei.
"Koro-sensei!" They shouted as the yellow octopus was launched into the air and struck repeatedly.
He had to win, Harry thought. If he didn't…then what?
"In exchange for only three months to live, I've made it so that he can tap into that energy of his." Shiro continued monologuing.
"And there's not even any danger of him exploding to death." He laughed, "A safe and flawless weapon, don't you think?"
Weapon…weapon…that was how he saw them as? Harry's eyes widened.
Come to think of it…he'd always been a weapon, hadn't he?
"You're always doing this!" Kaede shouted, "You're always hurting people, just laying back and watching from the sidelines!"
Suddenly Shiro tensed and…his head rolled right off his shoulders.
They all turned to Harry who had sent a slash of white light towards his head at the speed of a bullet.
"I won't let you ruin anymore lives." Harry whispered.
"Harry…kun?" Kanzaki said.
They were all stunned.
"I've killed before." Harry said softly, "And that man had something more up his sleeve. At least this way, he doesn't interfere in the fight. Besides…if I hadn't he probably would have."
They all still seemed surprised by his actions.
And why wouldn't they? No one had died in front of them before…well, most of them anyways (he thought of Kaede).
Koro-sensei's speed seemed to be picking up. He was using the dirt and the ricochet to compensate for speed.
The monster's eyes then turned to Harry.
Harry knew it was going to happen before it did.
The tentacles came down. He'd barely managed to cast a shield charm.
Harry let out a cry as the tentacles came down on the shield again. His arms shook under the pressure. Blood dripped down his arm.
"Harry!"
"I'm fine." Harry assured them, "Just…tough holding this thing back."
Thankfully, Koro-sensei was fighting it again. The Reaper glared at Harry angrily before returning to his fight with Koro-sensei.
"Can't believe I pissed that thing off." Harry lamented his bad fortune.
And then, both Koro-sensei and the Reaper launched a beam of energy at each other in mid air.
In the end, Koro-sensei stabbed the Reaper right through the heart, killing him.
Harry thought he saw his human form in the dust just for a moment before it vanished.
Koro-sensei fell to the ground, right in front of them.
"Ah. I tired." He said.
They all stared at him.
"Class…what kind of assassins would let a dying target get away…right in front of them?"
Harry's eyes widened, they were going to kill him?
"Fun times…are bound to end." He said tiredly, "That's what a classroom's all about."
There was silence, and then…
"Guys." Isogai spoke, "We need to decide this for ourselves."
They all shifted closer to him.
"We could choose to stay out of it and leave it all to fate or…" He looked left and right, "Show of hands…who doesn't want to kill Koro-sensei?"
Slowly…they all raised their hands. Harry did as well.
"Okay. Hands down." Isogai said, "Who wants to kill him?"
No one raised their hands and for the first time, Harry didn't know what to do. It was like somehow, fate…was drawing them to this point.
They circled him, they got down and held him down by his tentacles.
"You can't get up this way, can you, Koro-sensei?" Nakamura spoke.
"Exactly right, Nakamura-san. I am a bit worried about your grip though."
Some of them were shaking, some of them were crying.
"Your heart is under your tie, right?" Kataoka wanted to confirm, "Who's going to…"
They all looked at each other helplessly.
"Will you let me?" Harry asked them uncertainly, "I…" He drew in a deep breath, "I'm already walking this kind of path. I came to Japan originally to learn how to kill someone. If I can't kill Koro-sensei…" Harry trailed off.
They were all silent and then there were some slight nods. No objections.
Harry took out his anti-sensei knife from his belt.
"Before I go," Koro-sensei spoke, "I need to say goodbye to the two senseis over there."
Harry turned slightly, he'd hardly noticed Karasuma and Irena arrive.
"Are you sure you don't want to join, Irena-sensei? Here's a chance at part of the bounty."
But she opted to stay out of it.
"This assassination is the bond between you and those kids." She said sadly.
"And you? Karasuma-sensei? You two have helped make these kids what they are today. Please continue to offer your guidance."
"You may have offered me no end of trouble, but this is one year I will never forget." The man said solemnly, "Sayonara, Koro-sensei."
"Now then," Koro-sensei said, "Now is the time…Twenty-four hours wouldn't be long enough for me to say goodbye to each and every one of you in turn. We can't talk long, so, instead, I'll take attendance one last time. Please look in my eye and answer with a strong voice."
Harry felt his heart speed up and tears enter his own eyes.
This was really…happening?
"Once you've all responded…you can kill me." And then he started to freak out, "N-No one left early did they? If someone left now, I don't know how I'd deal with myself!"
"Just do it already!" a bunch of them shouted.
He lay back once again,
"Well then…Akabane Karuma-kun."
"Here."
"Isogai Yuma-kun."
"Here."
"Okajima Taiga-kun."
"Here."
This went on…but it felt all too soon that they were reaching the end. Harry was the twenty seventh seat.
"Potter Harry-kun."
"Here."
"Ritsu-san."
"Here." The AI's voice came out of Nagisa's phone.
"Horibe Itona-kun."
"Here."
Koro-sensei looked up at the moon,
"It was a really, really fun year. I'm so happy I got to be killed by you all."
Harry took his knife from his sheath.
"From one traveler to another. A yell for all of life."
Harry felt tears fall down his face shamelessly.
"You were the best teacher I ever had." He murmured, "When no one cared…when I thought I didn't have a choice…you showed me that I did. I…thank you."
"Smile, Harry-kun." Koro-sensei said softly, "Give me a pleasant send-off."
Harry managed to force his lips up into a smile. He brought the knife down through his tie and then…his body began to glow with a golden light.
It traveled up into the sky like the sparks off a fire.
Then, they all started to cry freely.
…
00000000000000000
…
The next day was the graduation day at their school. They were all dead on their feet and still grieving. They'd found diplomas on their desks, a yearbook and…Koro-sensei's Rules to Live by.
Both were perhaps the two thickest books Harry had ever seen, and having spent a good portion of his life in the Hogwarts Library, that was an accomplishment.
Lugging them all back to his temporary apartment was also an accomplishment.
Harry flipped through some of the yearbook and found himself smiling fondly at the memories and photographs.
What a strange life he was living…
"Yes, a very strange life."
Harry turned around suddenly to see someone was in his house with him.
It was the Animetopoeia. She was dressed in her usual sailor girl uniform and smiling happily,
"So, it seems your time in this world is up."
"It's…up?" Harry whispered, "Oh."
"Oh?" Ana tilted her head to the side, "You seem disappointed."
"Well…my teacher did just die…" Harry said quietly, "I guess…I'm still sad."
Plus, he'd killed him with his own hands.
"Well, pack up your things." Ana told him, "It's time to move on."
"Pack…I can pack?" Harry wondered.
That was an option?
"Of course, you can, silly!" Ana giggled.
Harry bit his lower lip and started packing up his bag fully of things. Whatever he thought he'd need…only, there was a lot he was holding onto, it seemed.
"You need a bigger bag." Ana nodded, and then…the bag seemed to magically expand on the inside. The outside made it look like a regular, brown leather backpack.
"Thank you." Harry said, then looked over at her, "By the way…when will I be going back to my own world? I mean, it's been a year…"
"Don't worry." Ana waved him away, "When you get back, no time will have passed. You aren't even aging. Haven't since the day you got here."
"Eh? Really?" Harry wondered.
It was true…he'd noticed the other kids had grown taller and he seemed to be a bit behind but…he'd always kind of been short…That meant…he was still fourteen?
"Time to go."
And then, a black hole opened up beneath Harry's feet and he was falling. Falling, falling down and down…
And then he was on a ship.
