Hey guys Crimson here and before we continue with the story, I wanted clarify a few thing before we continue with the story. Firstly Korosensei doesn't know that the siblings are related as I think I would have trouble with the interaction with them both. Korosensei will find out in later chapters, maybe around the time Ritsu comes in. I won't list who doesn't know as some of Class-E either know or don't know which I'm keeping it that way. I think the only problem I might have is with Kayano which I think I can avoid easily avoid. But anyway please enjoy the chapter.

Third P.O.V

"I wonder why Kanzaki-san wanted to spend the lunch together with Nagisa-kun out of everyone in the class." Nakamura commented while hiding in the bushes with Karma. "She probably has a plan to kill Korosensei and wants to know all of Korosensei's weaknesses perhaps?" Karma replied back to his partner in crime but it was also a lie. "Oh come on Karma-kun, you can't honestly believe that. But there and again, why would the class idol wanted to eat lunch with a guy like Nagisa-kun?" Nakamura replied back. "There can be many reasons why she wanted to talk to him but Nagisa-kun isn't like the other guys. Karma replied as he doesn't want to reveal that Yukiko is Nagisa's sister.

"Who do you think Nagisa-kun would chose between Kayano-san and Kanzaki-san?"Nakamura asked her partner in crime to see which girl does he think Nagisa would chose. "My money's on Kayano-san for many reasons, as I'm pretty sure he's a lot closer to her than he is towards Kanzaki-san." Karma replied back to his friend.

Nagisa P.O.V

I'm walking home with my sister Yukiko along with Karma as Kayano's house was elsewhere's while we had to take the train to get home. "Well I guess I see you guys tomorrow and get home safely okay?" Kayano told us as we aboarded the train as she waved back to us which we waved back. "Well considering that Kayano-san is now gone and that now it's just us three. You guys no longer have to play pretend and you can now be yourselves." Karma told us as nobody in our class actually knows. "I still feel bad tricking everyone and not telling them that Nagisa is my brother." Yukiko replied back to Karma. "

Well imagine that if the class were to somehow find out that you guys are in fact related. Well lets just say that they won't be leaving you guys alone. Especially Nagisa-kun as they be asking him all sorts of question." Karma replied back to Yukiko but he's right. Everyone would be asking all sorts of questions but most importantly, the guys will probably ask what does Yukiko's likes and dislikes. "I still remember how I first met you Karma-kun and when you found out that I was Nagisa's sister, you didn't even care." Yukiko commented and she was right as Karma wasn't bothered by it.

Flashback by Two Years

Third P.O.V

It has already been a week since Karma had befriended Nagisa after he had saw Nagisa reading one of Karma's favourite magazine series known as Sonic Ninja. However, today he's going to discover something else about his new friend. "Hey Nagisa-kun, have you heard? They'd just released another volume of Sonic Ninja as I saw it in the store while walking to school and wondered that we should buy it together while we walk home." Karma had explained to his friend while being stared at by some of the girl who think he's dating Nagisa. "I'm sorry Karma-kun, maybe another time. You see I'm going to be walking home with my sis-" Nagisa couldn't finish his sentence as he got interrupted which caught boy boy's attention and it was a girl running towards them. "I'm sorry that I kept you waiting Nagisa. You see- Ren-kun from Class-A wouldn't leave me alone no matter how many times I tell him to stop." The girl apologised to Nagisa while panting after running towards him.. "Yukiko, it's alright, besides I was just speaking with Karma-kun and he just asked me did I-" Nagisa was interrupted but this time it was by Karma as he just realised something about the the two.

"Wait a minute... you have a sister?" Karma had asked as he noticed that both Nagisa and Yukiko both have the same hair and eye colour. "I guess you noticed huh?" Nagisa replied back to his friend. "I'm guessing your Karma Akabane then... It's nice to meet you Karma-kun and I hope my brother hasn't caused you too much trouble." Yukiko greeted herself to Karma which he just smirked. "HEY! What are you mean by 'too much trouble?' I don't cause you any trouble Yukiko and I certainly don't cause Karma-kun any trouble." Nagisa replied but Karma just laughed over Nagisa's reaction. "Why what sort of trouble does Nagisa-kun cause you, Yukiko-san?" Karma had asked Yukiko, wanting to know what 'trouble' does Nagisa cause her. "Well... let's just say that he can be-" Yukiko couldn't finish about what she was saying as Nagisa quickly covered her mouth preventing her from answering Karma's question.

Ten minutes later

Karma P.O.V

After learning that Nagisa had sister and that he was waiting for her so that they can walk home together, I decided to tag along with them. "So Karma-kun... I've heard some disturbing rumours about you and because now your friends with Nagisa... Well... you could say I'm a little concerned about him." Yukiko told me and I can tell she's worried about Nagisa being friends with me because of my reputation. "You have nothing to worry about as I try not to get Nagisa-kun involved with anything that would get him into trouble. But it's perfectly understandable for siblings to worry about each other." I replied back to her in which she sighed in relief and gave me a smile. "Even though Karma-kun sometimes skips class and he may be a little devious sometimes. But he's actually the top of the class." Nagisa explained to his sister which caused me to chuckle. "Wait, so the rumour about that he skips class is true?" Yukiko asked which I just smiled. "It's true that I do skip class as my grades are better than everyone's else's. Heck even the teacher puts up for me." I explained back to her which is true.

Later

Yukiko P.O.V

After we said our goodbyes to Karma, me and Nagisa decided to head straight home before our father gets angry with us for being late. "So Yukiko, what do you think of Karma-kun that now you met him in person?" Nagisa had asked me as we continued our way home. "Well... You already know that I was concerned about you being friends with Karma-kun because of the rumours. But I'm glad that I was wrong as I wasn't expecting for who he truly is when he isn't being devious." I replied back to my brother. "Sometimes I wish I was like him as how someone like him has amazing grades even though he's laid back. But I think if father heard me say that, he'll just constant yell at me for getting into trouble." Nagisa replied back but we decided to change our topic as we made our way home.

That's all for now you guys and sorry for the long halitus, I've been busy and my mental health as caused me trouble which effected my motivation to write. I'm so sorry as I want the chapters to be amazing and something different. I want to take my time to write chapters while not focusing on following Assclass's story but I will follow certain events but not all of them. But anyway's thanks for reading and I see you another time.
