Machiko's P.O.V

As I walked out of the classroom. Kayano came with Karma, Nagisa, Isogai plus Nakamura and asked "Hey Machiko-chan do you want to sit with us in lunch?".I smiled and said, "I want to, Kayano-Chan."We went outside, sat to grass, and opened our lunch boxes."So what is your story Machiko-chan" Karma asked."Well, it's a little long but to put it simply my biological father was Yoru Sayako. They got assassinated, I was sent to an orphanage, Karasuma-sensei adopted and trained me." I explained. They looked shocked. I thought that they were waiting for a happy childhood, not a rough childhood with losing both of your parents."Wh-whoa that was very...rough."Nakamura spoke up."Yeah and it must have hurt you, I mean losing both of your parents. I am sorry for your loss."Nagisa stated. I thanked him. We ate our lunch. The bell rang. We got inside and it was time for the math lesson. We sat down and Koro-sensei walked in. He started to tell us about today's lesson. I took notes though I knew this topic."Sayako-san can you solve this problem?"Koro-sensei asked and wrote this question to the chalkboard 'Each dimension of a cube has been increased to twice its original size. If the new cube has a volume of 64,000 cubic centimeters, what is the area of one face of the original cube?' most of the class just stared at the question."Pfft, that is an easy one. Let x be the length of the edge of the original cube. When increased to twice its original size it becomes 2 x which gives a volume of
2x × 2x × 2x = 8x3
The volume is known. Hence
8x3 = 64,000
x3 = 8,000 which gives x = 20
The area of one face of the original (before the increase) is given by x2
By this x2 = 202 =so the answer is 400 square centimeters" I answered. Koro-sensei and the whole class looked confused."Nyfufufu~ Correct!Good job Sayako-san!Let's move on."Koro-sensei said. I kept taking notes and answering the questions Koro-sensei asked me.

    The last bell rang and I waved to my new friends. And started walking down with my dad."So how was the first day of school?" he asked me. "It was great! I made new friends, I sliced five of Koro-sensei's tentacles, and had fun with lessons even if they were too easy." I confessed to my dad. He stroked my head and told "Great. You know tomorrow your first lesson is physical education with me, right?" he raised a question. I nodded my head and proclaimed " Of course, I know and I am looking forward to it."
