A/N: The woman's dialogue is on italics.

On an old shack on the top of a hill, in a croom filled with chairs and tables, there was big piece of machinery on the back of that room. It was huge and black, with a dusty screen in it. It looks like it was abandoned for years.

Suddenly, the screen glowed, as it suddenly turned on by someone, which is weird because the shack was actually deserted for years.

Then it glitched for a few seconds, as jumbled numbers were flashing on the screen. After the numbers vanished, the screen became static, before it shows a person in a dark cloak, her face was covered in its huge hood. It was a woman obviously, possibly in her teens, but her voice sounds mature than she looks. She was holding a huge book, a little old, but still as good as new.

Then she smiled, as she opened the old book, looking at the pictures contained inside, as she started to narrate.

"I remember it like it was yesterday..."

It was 7 years ago, 70% of the moon was shattered, and no one knows who did it, they thought it was just an passing asteroid destroying it.

But one day, in a little hill where a little shack some kids called a classroom was standing, a strange octopus-like creature came, and claimed that he is the one who destroyed the moon, and will do the same thing to the Earth in a year.

He had said that he need to be assassinated in a year, before they graduated, therefore dragging those 28 children into a world of assassination.

The higher authorities had promised everyone, that the students of the End Class will claim the bounty, if they managed to kill the monster who was teaching them, they will help the kids with the assassination.

The creature taught them a lot of things, from academics to life lessons, while these kids try to kill him. While at his care, the End Class rose to the top, thanks to him,as they were breaking the norms of the school.

Eventually, little by little, the students came to love him, but never admitted it, for the fear of breaking their bond.

One fateful day, one from his 28 beloved kids had shown her true self and take revenge,paving their way to finding out about his true past, being a great assassin and all. He was truly doomed, bound to explode at the day he claimed he will destroy the whole world.

A civil war was waged, as they were to decide whether to save or kill their teacher. It was a great fight, but at the end, they were united together to save him, even after finding out about the possibility of him not exploding.

But all this time, they were betrayed by the higher authorities,they were now one step ahead from them.

He was caged by a shield of Earth, doomed to be dispersed by a spear of Heaven. His students were on their own, to see him, even for one last time.

They fought their way, and here they are, with smiles on their faces, they celebrated his given birthday. It was very joyous...

...Until it was distrupted by his creator and the creature's former student. They came back to kill him, to avenge their lives.

They fought for revenge and spite, tentacle to tentacle, with a battle of Mach speeds and sonic booms. It was his last stand, his last fight to the end.

With gratefulness and regret, the student who formerly attack him in revenge helped him fight, for him and for her deceased sister, distracting the enemy so the creature can heal...but in return, her life was taken away by a stab so fatal.

His creator taunted him, saying mean words to the woman he had cared, the sister of his beloved student.

Out of regret, sadness and rage, the creature's face changed into a grostique form, his aura emits a menacing one, while his face wrinkles and turns black. His true self, the monster he was trying to hide after all these months, was finally set free.

His creator laughed crazily, as he saw the tragic sight infront of him, as the teacher unleashed his true self. The creature's beloved first student, now changed into a grostique creature, takes watch, before attacking his former master with his own powers, aided by the creator's help.

It was very bright, as the teacher and the student fought with all their might, as a huge beam coming from them clashes at last. It was a spectacular sight, if not the situation so tense.

But the teacher never lets his anger take over him, he had channeled his powers through a myriad of emotions, which turned a rainbow of colors, used to defeat his first student, as their memories flashed between their eyes.

With a stab in the gut, in a flash of bright light, his first student was defeated, his dying words says his true wish, the recognition he wants from his mentor. The teacher smiled sadly, as his young apprentice disappeared from sight, floating away in specks of light.

The teacher approached the bloody body of his precious student, with sadness in his beady eyes. He started to remember his student's older sister, who suffered the same fate as her. It was still etched on his mind, that tragic day. With determination, his little tentacles started to do its miracles, trying to heal her. He fixed and revived her, her blood replenished, her wounds gone, it is a miracle for everyone.

She woke up, grateful for the teacher, even trying to hide her embarrassment over little chest.(The narrator chuckled.)They were happy to see her alive and well.

But their happiness stopped, when the creature finally fell down in exhaustion, satisfied with his doing.

But his next words shocked his students and his two colleagues.

"It's time."

And 30 people around him knew what it means, and they dreaded it.

It is time to say goodbye.

The woman wiped her eyes, but she still kept that hood on.

With hesitation, they approached the exhausted teacher, their hands shaking, as their hearts pounding so fast. Some tried to stop their tears from falling.

They tried to be strong.

Can they do this?

Will they do this?

Are they ready to let him go, their precious teacher?

These thoughts haunted in their minds.

They had decided and raised their shaking hands, as their leader asked them. They don't want to kill their sensei, but they had to.

With shaking hands and broken hearts, they held him down, his weakness. They hold down his tentacles, one by one, while the two grown ups stood beside them, and looked at them with sadness.

The creature looked at them sadly. If only he was spared, he would be with them for a little longer and see them grow into successful grown-ups they will be.

An inffeminate boy volunteered to deliver the last blow, the stab to their teacher's heart. No one relented or even argued, they knew he deserves to do that honor, for he was the best assassin in their class.

The creature entrusted the students to his two dear colleagues. He knew they would take care of his precious students when he was gone.

With heavy hearts and crying eyes, the last roll call was delivered.

Their names were called, as they struggled to answer without crying. They can't bear it, the sadness this moment bring.

They don't want him to go.

One by one, each student was called, until he had mentioned the last student, and softly spoke about how they were proud of him.

The inffeminate boy struggled to do the job, his hands shaking. He hesitated to deliver it, as he tearfully looked at his teacher.

He was tense, his nerves were shaking, and he could swear his emotional wavelength was too high.

Until he can't take it anymore.

He screamed loudly, as he harshly raised his hands in preparation to stab him.

But he was stopped by his teacher's gentle tentacle holding his nape, calming him. He just wants the boy to smile, for him. He couldn't bear to see his student cry, even at his last day. He just couldn't.

The boy just smiled as he calmly pointed the green knife to the creature's necktie. With tears in his eyes and a smile on his face, he had said his final words for his dearest sensei.

"Goodbye...Koro-sensei."

The creature smiled, as he looked at his student for the last time.

"Yes, this is goodbye," he spoke softly. He looked at his other students and smiled softly.

Alas, the boy pushed the knife to the creature's heart, as the creature closed his small eyes, his last dying breath was now gone. The boy looked at his teacher, as specks of yellow light started to appear from the creature's body.

Twenty-eight students and 2 teachers looked in awe and sadness when the creature's body started to turn into glowing specks of yellow light, floating away to the barrier and to the crescent moon, leaving his ruined clothes and grieving Class E family, as the specks of light disappeared to the dark skies forever.

The woman in the screen smiled sadly, as her lower part of her face was shown by the light of her room. She was looking at the book with longing, her little fingers swiped at the pictures in the current page gently.

She hummed, and gently closed the old book, before looking outside at the room window, as far as the screen's angle could see.The broken moon, which returns its round shape after 7 years, although a little smaller than before, has magically turned into a crescent moon again. It was like the one from 7 years ago.

For someone who never knew the whole story, they will think this was very weird, but the woman knew.

She looked at the closed book again, and continues to speak.

"Nobody knows we're still here,

Smiling beneath the moon while remembering our dear teacher..."

Then the woman removed the hood from her face, revealing a young-looking face, with blueish eyes and light purple-pinkish hair tied into unique pigtails, adorned an electronic-looking headband.

It was the Autonomous Intelligence Fixed Artillery, also known as Ritsu.

Ritsu looked at the moon again, with a smile on her face.

"...for we will be his children of the crescent moon."

Then Ritsu's face fades away before the screen turns into static and turned off, possibly for the final time.

A/N: Hello, I am back with this sorta new chapter.This story was actually created one year ago, when I hear Erutan's version of the song "Come Little Children" from Hocus Pocus, and the MLP animation video, "Children of the Night".It was supposed to be a multichaptered story, but apparently I only wrote two chapters because I lost interest. Although, I have plans to revamp the story, but it is still undecided as of now.

The original title of this is "Children of the Crescent Moon", but I changed it because I have an ongoing fanfic story with a kinda similar title.

As you can see, it was just focusing on retelling the plot of Assassination Classroom on the point of view of someone else. The second chapter of this story is where the creepy thingy started.This was actually made on my old phone's messaging app because it was a crappy phone.
