Part 22~Autonomous Intelligence Fixed Artillery

"Wait, I don't get it," Koko tilted her head. "If this girl isn't an experiment, how does she have tentacles?"

Nagisa sighed, leaning against his hand. "I have no idea, but I'm not going to pry. Would you like someone prying into your time in the lab?"

Esumi and Koko shared a look. "No."

"Just practise your surgery skills so we can convince Kayano to let you remove it." Nagisa stood up with a frown. "I'm going to wake Keiji up. I want to get to school early."

"When don't you?" Koko laughed, leaning against Esumi's shoulder. "So... Want to play doctors?"

Esumi blushed, squeaking. "What?!"

~~~

Nagisa hummed, dragging Keiji up the hill to class. "What's got you so happy? I thought you were stressing about Kayano?"

"Well, yeah, but we don't have to worry about that right now." Nagisa grinned, glancing over his shoulder. "We're getting a new classmate."

"I thought you would hate that."

"Not this one." Nagisa continued walking away as Keiji tilted his head in confusion.

"Why are you being social?!"

~~~

"Oh, I get it now." Keiji sighed as Nagisa beamed, moving around the big black box.

"It's so pretty."

"I swear, if we get replaced by a robot, I'll never forgive you." Keiji frowned as Nagisa laughed.

"Don't worry, I won't replace you."

"Really, because you already love your laptop more than me, and that can't talk."

Nagisa rolled his eyes, throwing an arm around Keiji's shoulder. "Awe, are you jealous, Jiji? And here I thought you trusted me."

"What? Me jealous? Never."

"Dude, you had a mental breakdown at the thought of me not dating you."

"No, at you replacing me. I'm being very on brand." Keiji pouted as Karma snorted.

"Good to know you're consistent, at least."

Keiji screamed, jumping away from Karma, and he and Nagisa laughed.

"Don't freak out on my account."

"I hate you both," Keiji grumbled, crossing his arms as Nagisa laughed, rolling his eyes.

"Sure you do." He paused, whispering into Keiji's mind. "After all, we both know how much you hate Karma's 'stupidly messy hot hair.'"

Keiji hissed, glaring at Nagisa and screaming back into Nagisa's head. "Shut up!"

Nagisa laughed, ruffling Keiji's hair. "You're so cute."

"Good morning," the class paused, turning to face the black box. A picture appeared on the screen of a young girl. "My name is 'Autonomous Intelligence Fixed Artillery.' I am the new transfer student. Nice to meet you."

Nagisa grinned as the screen turned off. "It talks."

~~~

Karasuma knelt before the AIFA, placing a hand on its back. "Class, this is our new student. Her name is 'Autonomous Intelligence Fixed Artillery.' She's from Norway."

The screen turned back on, displaying AIFA's face. "Nice to meet you."

"Stop laughing. This is no occasion for mirth! You're no better than her. Let me remind you, 'she' might be a computer, she might have a complex A.I., and yes, she might be an assassin, but she is also a registered student, and according to your contract, you can't harm a student."

Koro-sensei nodded, chuckling to himself. "I see. Using the contract against me by enrolling a computerised weapon as a student. Okay then, Autonomous Intelligence Fixed Artillery, welcome to Class E."

Nagisa grinned, watching the AIFA as Keiji glared at her. She didn't like the robot.

~~~

The class waited as Koro-sensei stood by the blackboard, teaching some difficult maths Keiji couldn't decipher.

Everyone was waiting for the AIFA to do something.

Creaking echoed out as the machine guns sprouted from AIFA's sides. The room was splattered with BBs as Koro-sensei dodged.

"Wow, four shotguns and two machine guns. An impressive barrage, but my students have shot at me like this every day, too. By the way, students aren't allowed to shoot me during class." Koro-sensei pushed away the last BB with his chalk.

AIFA's face appeared again. "I will be careful. Preparing for the next attack." The guns disappeared again as the grinding sound ground out. "Recalculating trajectory. Adjusting firing angle. Advancing to self-evolution phase 5-28-02."

Koro-sensei laughed, the green stripes appearing as the guns shot out. "Not following instructions, eh?" The bullets splattered around Koro-sensei as he laughed, the attack the same. He swatted away the last BB, gasping as his finger burst.

AIFA hid a BB behind the last shot. "Right, tentacle fingertip destroyed. The newly added secondary gun has proven effective. Probability of killing you with the next attack less than 0.001 percent. Probably of killing you with the attack after that less than 0.003 percent Probability of killing you before graduation more than 90 percent." AIFA smirked as the class watched in horror. "I'm looking forward to being a member of this class, Koro-sensei. Moving on to the next attack."

The bullets splattered around again as Keiji sighed, covering his ears and hissing into Nagisa's mind. "Still think she's so cool."

"We have to stop her."

"We will."

~~~

The class grumbled in annoyance, staring at the floor. "We have to clean this up?" Isogai stared in horror as Muramatsu turned to AIFA. "Don't you have an auto broom or something, miss Fixed Artillery?"

The AIFA didn't respond. She only cared about killing Koro-sensei and didn't care how much of a mess she made while doing it.

~~~

"Hey Nagisa," Keiji stopped Nagisa as they approached the house. "I've been meaning to ask, if we're going to keep sabotaging everyone, how will we stop Koro-sensei from destroying the planet."

Nagisa paused. "I don't know. I guess I forgot about that." He laughed, scratching the back of his neck as Keiji raised his eyebrow. "Oh, don't look at me like that. I've had a lot to think about."

"That's the point. Nagisa, you're having to deal with finding out about the third skill, finding the other survivors, stopping the assassinations, a number of identity crises and being kidnapped. Trying to fix Koro-sensei so he won't blow up the world, I'm not sure you can manage that too."

"You... You want me to give up?" Nagisa stared at Keiji in horror, stepping back as Keiji took his hands.

"Of course not. What I was going to suggest is, let me do it. I'm not great at the whole reading and writing thing, but if I work with Koko, we can brainstorm together. She even uses a dictaphone! It's perfect."

Nagisa hummed, a soft smile appearing on his face. "That's not a bad idea. But, are you sure you can handle Koko?"

"I can handle you, and Voila, how much worse can Koko be."

Nagisa opened the door as Koko screamed. She threw everything she could get her hands on at the corner as Esumi tried to stop her. Erika was cowering far away from the chaos, shaking and rocking back and forth as Jin tried to protect her.

"I'm starting to regret this."

"Too late!"
