KARMA AKABANE'S POV
We finally arrived, and then we saw a large screen at the back of the classroom.
"Hmm? What's this for?" I looked closer to it and it turned on.
"Hello everyone... My name is Ritsu, and I am the new student. And I shall also be participating on Koro Sensei's assassination." I was a little confused of what was happening, but some boys were much more discouraged when the new student (which was a girl) is an AI. She was attacking Koro Sensei with her armored screen and it was too noisy, that we couldn't hear what Teacher Koro was talking about. And the same happened after that day. Since we were so pissed, we dismantled her guns and armors before she was activated. Then finally, peace of mind.
"Huh? What happened to my armors?" Ritsu asked.
"Oh, we just dismantled it. We just don't wanna be interrupted on class." I replied.
"But you wanna kill him, right? Don't tell me your making excuses since you're protecting your teacher, isn't it?" She said.
"Don't get me wrong, we wanted to assassinate him as well, since he will destroy earth. But he's also a surprisingly good teacher and we need him to teach us so that our grades will improve. Also, we assassinate him by teamwork, and it is very important to us. Hopefully you'll understand." Nagisa explained, while Ritsu just stared at us, going back to our desks and sat down. She mostly stood there quietly, and impatient. After class, I walked home with Manami which was also our new routine. We mostly talk and sometimes I would tease her, and I realize... 'For a demon like me, I don't think I deserve this. She makes me happy, yes. But is she happy whenever she's with me? Is she happy sacrificing her punctuality, just to walk to school, late, with me?'

The next day...

My alarm clock rang and I woke up and prepared for the boring class. 'But I guess it wouldn't be that boring this time since Manami and I planned to walk to school together this time.' We arrived at the school after that fun chat I had with her, 'It was more fun than I expected eh.' We walked in the classroom, five minutes late as usual, for me. But for her, it wasn't the usual. We sat down and and noticed something... It was Ritsu, she was much more different and unarmed today.
"Koro Sensei customized me so that I would fot in with you guys. Also, I realized how teamwork is important, and it helps us a lot!" Ritsu said, exclaiming happily unlike before.
"Nyeehehehe! By the way, I use up my money just for her personalized custom." Koro Sensei claimed happily, and frowned all of a sudden. "Waaaah!!! I used up all of my money!!!" He was running around like crazy, but now he's also a broke tentacled man. (Or yellow octopus, if you prefer XD)

KAEDE KAYANO'S POV
'I've been hearing rumors, lately. Some of it are about me and Nagisa, but what? What's the fuzz all about between me and him? Welp, I guess I'll have to wait till this Saturday.'
