Autistic-Grizzly: Ummm... It is not a NagiKae moment there... But I'll let you think that way then! I really do not intend to add in any pairings other than Karasuma x Irina. But if some of you guys want some pairings, I may add in a few different endings for the story. But for now... just no pairings.

SSJ Mirai Gohan: Thank you for the compliment! I am glad that you enjoyed this fic, and I hope you enjoy this chapter!

Cloy552: Hey, thank you for that awesome line that I am going to insert in this chapter! Do you think that I would really make Nagisa kill Koro-sensei? It just doesn't seem right, as the E class had been trying to kill Koro-sensei for a few months now.

Writer and Reader D: Thanks for the compliment!

ynius: Aheheheheh...

Palpex: Gakuho will always be a jerk, along with that son of his. Thank god that I haven't dragged Gakushu into this. Yet.

FoxcatAl: Heheheheheheheeeeeeee!.! Me evil.

Hey peeps! Here is the ninth chapter of Crystal Tears as promised! Once again, I am really sorry for not updating sooner, I had exams as I told you all before. Also, I have been rewriting this chapter a lot. I wasn't really satisfied with the writing, so yea... Hopefully, this chapter will be enough to compensate for my ineptness for being unable to update last week.

Disclaimer: Nope. I do not own Assassination Classroom at all.


Chapter 8: The REAL Challenge

Bitch-sensei carefully painted her nails pink, though her anxiety could be felt by the teachers in the staffroom. She had just dropped Nagisa off in the E class and they are now awaiting the arrival of Asano Gakuho.

Karasuma shot a glance. "Irina."

"What is it?" she snapped back irritably.

"When this job is over, I want you to quit being a hitman." he said nonchalantly. "You're not suited for it."

A tick appeared on her forehead. "Excuse me?" She asked.

His eyes scanned the documents as he replied. "Your emotions are too deep. Over this year, that depth has reached a fatal point. Just from seeing the emotions you feel for the students... I can say that your job will only get harsher for you."

She clenched her hand. "Easy for you to say, Mister Straight-and-Narrow. You can't just deny this life of mine, built by dancing with death too many times to count. I've killed lots of people. After ten years of experiences tainted with sin... I don't have any right to go back to a place touched by the sun."

"What about Nagisa?"

Then it hit her. She hadn't thought of that. What about Nagisa?

"What will happen to him if you die?"

She bit her lip. "Fine! Tell me what I should do!" She snapped.

He put down his documents and stared at her. "Irina... Come work at the Ministry of Defense. Even in your peace, your experiences will certainly be of use. We have an intelligence department that won't pry into your past. There, you'll be able to save more people than you've killed." He paused, as if hesitating to say something. "And every morning, you can stop by the shrine and pray for all the people you've killed."

"A shrine? I'm more like a Christian. And I do not have a house in Japan... neither do I have any relatives here..." She answered, though she is already considering the offer.

The stare he gave her changed one that almost looked scornful. "You don't get it? There aren't any churches near my house."

She blinked once.

She blinked twice.

Then realization dawned onto her.

"EHHH?!"

"Nyuya! Ah, the beauty of romance!" The residential octopus of the staffroom barged in and ruined the conversation.

The both of them shot him with their guns. "Shut up."

Karasuma then turned his attention back to her. "Nagisa is more than welcomed. He is almost like a son to me anyways."

"Wait, Karasuma, are you saying what I-"

"I said what I said."

"But-Wait a," She panicked. "It's unbecoming of a man and a woman to live alone together under the same roof."

"If you don't want to, then live by yourself. I already said that Nagisa can join us, we will not be alone."

"No! I'll live with you!"

The sound of footsteps started echoing down the corridors.

The three teacher reacted immediately, as Karasuma and Irina stopped talking. They silently followed the principal down the corridor until they reached the familiar entrance to the E class.

"Ah, Shiota Nagisa... Where have you been this past four weeks?" They heard the principal asked with a pleasant tone, though the teachers knew better, the principal of Kunigigaoka High School is anything but pleasant.

"I was very sick, sir," Nagisa's soft voice answered the principal.

"Sick? I had called many hospitals to check up on you, you were in none. How odd."

Koro-sensei seemed anxious to save his favourite student from Gakuho's relentless questions, as he burst out stammering the next second. "M-Mr Principal! Please do not openly harass my students!"

What the insane principal did was unexpected for the teachers.

"Perfect! Just who I was looking for!" He proceeded to take an anti-sensei knife out of his pocket to give to Nagisa. "I've heard that you are a really talented assassin, Nagisa-kun... Can you give me a demonstration?"

Well, wouldn't that be nice. Bitch-sensei thought sarcastically to herself. Hey, go kill this guy you and twenty something other people have been trying to kill for the last few months just cause I said s. If it were that easy, Nagisa would have completed the mission already.

But... she glanced worriedly at the teal haired boy. Will he accept the challenge? He had two choices. Accept the challenge, and possibly face humiliation by the prinicpal, or decline and stand the chance getting expelled?

Nagisa ran.

She blinked owlishly. Or... he can discard the two choices and make a third one-run.

On a second thought, running away is also counted as declining the challenge... Then it hit her, Nagisa is running away. She needed to go after him. The past cannot repeat itself.

So she ran after her boy.


It was obvious to the E class that Nagisa was upset. As a matter of fact, they were angry with Asano Gakuho, who did he think he is? There he was, demanding that Nagisa finished off Koro-sensei when it is supposed to be their job as an entire class to kill their teacher together.

But Asano Gakuho is the principal of Kunigigaoka High School and they could do nothing against him.

The teachers, however, can.

Karasuma-sensei took a step forward, a hand stretched out and grabbed the principal's shoulder. "I believe we should have a talk."

Asano paused, letting his stare scan through the room as he did so. "Then talk."

"You have taken one step too far over the boundaries," the PE teacher stated in a curt voice. "You should stop."

The principal let out a low laugh. "Excuse me? This is my school, my rules. Put it short, this is my territory and you have no say to what I can do."

"Why are you so mean?!" Kayano burst out. "Nagisa doesn't deserve to be treated like that!"

The red headed principal raised an eyebrow. "You E class are getting bolder, I see. I just needed one of you to break, to confirm your status as dirt of the society, whose only purpose is to remind the likes of me that we cannot end up like you."

"Mr Principal..." Every one turned, shocked to see a black-faced Koro-sensei, whose presence just radiated anger.

The E class shivered, they had never seen their homeroom teacher this angry since their introduction to him months ago.

"I do not tolerate you insulting my students!" Koro-sensei angrily spat out. "We, the teachers, will talk, alone, somewhere else!"

Unlike the students, the principal just stood on the spot, looking undisturbed at the sight before him. "If you say so," he threw the class one last long look before stalking out of the classroom, Koro-sensei and Karasuma-sensei following behind him.


"Nagisa!" Bitch-sensei called out, as she ran after the teal headed boy. "Stop, please!"

For a moment, Nagisa slowed down, as if hesitant to obey her. She panicked, fearing that her boy will run away from her.

"Running away won't solve the problem, Nagisa!" She shouted in desperation.

He halted, allowing her to catch up to him and catch him as he fell on his knees. Tears were in his eyes as he trembled.

"I-I-" he stuttered, unable to from word.

She held up her hand, making her fall silent. "Nagisa," she said softly. "Who am I?"

He tilted his head in confusion. "You are Bitch-sensei."

She chuckled. "Yes, I am. But the correct answer is, I am your guardian. Your mother, to be exact, though we are not related by blood. " She paused, watching the emotions that flash past the teal headed boy's face. "The point is, you will always have me by your side if you ever face any trouble. I understand that you are nearly of age in a few years time, and that you have never really relied on others before, but as your guardian, I am willing to do anything for you."

He swallowed nervously. "I... I won't be a burden, will I?"

She hugged him tightly as if to squeeze away the amount of sadness in his entire self. "No, you won't. Because you are my son."

Hesitantly, he returned the hug. "Sensei?"

She looked up into the pair of teal blue eyes that were a shade lighter than hers. "Yes?"

"Thank you," he said, for the millionth time.

She smiled and ruffled his hair. "There is no need for thank yous. Now, why don't we head back to class? I am sure that your classmates and that insufferable octopus is worried by now."

He nodded, and allowed her to put la reassuring arm around him as they walked back to the wooden building of Class 3-E.


"You've hurt a child!" Koro-sensei roared at the principal of Kunigigaoka High School as they entered an isolated staffroom.

The principal raised an eyebrow. "I did not."

"You did," Karasuma cut in, his tone was angry, unusual of the man who normally keeps his cool. " Nagisa has already been through a lot. And it is none of your business what he'd been through. Stop bullying him!"

"The fact that he couldn't face his problems justify that he is in no condition to attend this school," Asano scoffed. "He will have to go."

"I refuse to let that happen!" Koro-sensei cried, his tentacles flying around but they avoided hitting the people in the room. The octopus is still aware that he could not injure anyone, especially in this situation.

Asano stood coolly, staring at the mad octopus before him. A smirk soon adorned his face. "Then prove it to me that he is worth being in this school."

"What do you want me to do?"

Eyes turned to the entrance of the room, where Nagisa stood, Bitch-sensei hovering over him protectively.

"What do you want me to do?" Nagisa repeated, his eyes staring at the principal determinedly.

The smirk on Asano's face widened as he stared back at the teal headed student, as if challenging him into a staring battle.

After what seemed like eternity, though in truth it was only a few seconds, the principal fished out something from his pocket and handed it to Nagisa. "You are a talented assassin, I have heard... I want you to find this man, capture him and bring him to me."

Nagisa broke the stare to turn his attention to the photo. Color drained from his face. "Th-This is..."

Bitch-sensei snatched the photo from his grasp. "Who is it?" She asked in confusion as she stared at the unfamiliar face.

"Otou-san." Nagisa whispered.


Cliffhanger, AGAIN! I'm so sorry guys! I tried my best and this is what came out! I do hope you all enjoyed it and did any of you recognize the Karasuma x Irina scene from the manga? I changed a bit, but it shares the same stuff. Tell me what you think about this revelation! Till then, ja~

Yours,
