Chapter 6: New student

Your pov
The trip had ended and I was back home. My aunt had already came back from her travels so I had to tell her if I did any assignments when she was gone. We had a very rocky relationship. Sometimes we could be having fun and laughing, other times she could be screaming at me. Karma knocked on my door like usual on school days. "Bye auntie!" I waved to her and opened the door. "Oh your aunts back?" Karma looked behind me to see her. I nodded and closed the door. "There's supposed to be a new student today?" I asked him as we started walking.  "Pretty sure it might be a student assassin." Karma held my hand and gave it a little squeeze. I giggled. "I wonder what they're assassination would be?" Karma agreed with me. "They'll be our first student assassin." 'First HA. Don't make me laugh.'

As usual we made it right before the bell rang. 'The students a box!?! Isn't she an assassin? I have no idea what to expect anymore.' Everyone took their seat and Karasuma sensei walked up to the chalkboard. He began writing something as he was talking. "As I'm sure you know, this is your new classmate." He moved to the side. "Autonomously thinking fixed Artillery from Norway." The screen then turned on to reveal a beautiful looking girl. "It's a pleasure to meet you all." And then the screened turned off.

Class began like usual. Karma throwing paper balls at me and sticking is his tongue out as koro sensei taught us whatever. I happened to look at the new student and saw a whole bunch of green lines. 'Collecting data?' All of a sudden guns were brought out from the sides and started firing. Since I was at the back right next to her I didn't have to take cover. Karma grabbed me and placed me on his lap. "Karma! Not now." I whispered yelled. He smirked. "I'm just protecting my girlfriend." I sighed. This continued all day. 'This is boring now. If she constantly attacks she can kill him. It's up to the people who programmed her.'

The next day before class had officially started terasaka had tied her up so she couldn't bring out her guns. "Don't you think that's a bad idea?" I asked tilting my head. "I don't care if it is or isn't. She's annoying with her stupid assassination." Terasaka spoke with an annoyed tone. I just sighed as koro sensei walked in. The purple haired girl came onto the screen and the sounds of banging were heard. 'Is she trying to deploy her guns?' Sure enough she was. "Koro sensei, I cannot deploy my guns like this. Please remove my restraints." 'Please don't.' "Well I don't know about that." Koro sensei scratched his head. "Is this your doing? It is clearly harming me, which is in violation of your agreement." Karma had grabbed my chair and pulled me back. I was about to talk when I saw terasaka throw the tape at her. Karma smirked at me. "Think again. It was me. You're a pain in the ass any way you look at it. Learn some common sense before you start firing away, you box of bolts." "Machines don't even know what common sense even is." I couldn't help but feel apologetic to the purple hair girl. 'She's a robot cut the crap angel. How stupid can you be. Leave her alone. Let her make her own decisions!'

It was peaceful that day. The machine didn't cause any disruption and we were able to learn. "Why are you always so nice to everybody." Me and karma were walking home when he asked me. "Huh? What do mean?" He sighed. "I could tell you felt bad for that machine. Why is that." I scratched the back of my head. "Eh, I don't know. She looks and talks like a person." He chuckled. "She's not a real person (Y/n)." I looked down. He clicked his tongue and grabbed my chin forcing me to look at him. "Your too nice for your own good." He kissed me and continued to change the topic.

~next day~

I entered the classroom to be met with a bigger machine next to my seat. 'Did she get an upgrade?' The girl came onto the screen with a big smile. "Good morning (Y/n)! What beautiful weather we're having!" I chuckled and smiled. "Yup! It's a wonderful day!" We both smiled as others came into the class. Terasaka scoffed at the sight and stomped to his desk. Karma walked up to me. "She got an upgrade?" Nagisa walked over. "Koro sensei did it." I chuckled. "Of course he did." I looked over at her and smiled. 'How cute!' "Don't be fooled! It's just some program the octopus loaded up. It might act nice, but a machines a machine. It's still gonna start attacking out of nowhere. The dumb box of bolts." Terasaka rolled his eyes as the machine turned to him. "I understand how you feel, Terasaka. I was like that until yesterday. Box of bolts... I don't know what to say." She started crying. "Look at what you did Terasaka." I pointed to the girl. "Terasaka made a 2-D girl cry." I shook my head at him. "Even (Y/n) is mad at you." Kataoka looked down in disappointment. "Cut it out! People will take it the wrong way!" At the end of the day we decided to call her Ritsu. "Since you can make things, can you make (favorite flower)?" I excitedly asked her. "Sure thing! Collecting (favorite flower) data!" I jumped from excitement. Karma smiled at me even though he had his doubts about ritsu.

I thought everything will be fine until I got home. It was dark inside. My aunt was standing and staring at me. Right next to her was a guy in a white coat. "He would like to make a deal with you angel." She glanced at me. When she refers to me as angel this means it's assassination business. I sadly knew where this would lead to. "What is it you'd like to offer?" I turned around not wanting to see his figure. "Whatever you want angel. But shouldn't you be asking what task I ask if you." I exhaled. "What is it you want me to do?" I stared at the wall waiting for his answer. "That creature did something to my machine and I want you to revert it back to the way it was." My eyes widened slightly. "I'm sorry but I decline it." 'I can't do that. The deals are only for me to kill people.' "The deals are made only if my task are to kill someone." I heard his laugh. "We'll technically you're killing the machines new personality." I shook my head. I heard footsteps behind me and I could tell that it was the unknown man. I walked more into the shadow away from the door. "What a waste of time. You really are an angel." The man opened the door and walked away. The man was asking to do something that I had created out of boredom. People love to call it 'A Deal With an Angel' but in all honesty it's just a deal. Usually people want me to kill others they can't kill. Of course I get something in return and the person I kill has to be a criminal. My aunt turned everything on and by the look on her face I was getting yelled at tonight.

~time skip~

I was scared as I walked into class. 'Will she still attack?' I could sense the others worrying about that too and just when we thought she would. '(Favorite flower)!!' Flower petals dusted the classroom. "I promised (Y/n) that I'd make flowers. Koro sensei made 985 improvements to my body. My master judged most of them irrelevant to assassination and removed them, deleted them, and restored my factory default. But from what I learned of the E class, I myself decided that my ability to cooperate was essential to assassination, so before it was deleted, I hid the relevant software in a corner of my memory." I stuck my hand out and a petal slowly fell into my palm. I smiled and karma went up to Ritsu. "You think you can hand me a few?" He stuck his hand out as Ritsu nodded. Karma went to my desk holding a bouquet of (favorite flower). "These belong to you." He winked at me and I smiled widely. "Thank you!!" And just like that we had another student.
