What if Ayanokouji had a brother

Episode 1

Kiyo pov.
The entrance ceremony was boring, but it helped me find interesting information about the school. Yuki was hugging my arm and Shiro was walking next to me as we walked towards our classroom. I don't know why Yuki is hugging my arm, but it feels nice to have her hug my arm. Thanks to Matsuo, we were able to enroll in this school so that we can enjoy our freedom for 3 years. My thought process ended when Yuki stopped me.

Yuki: Come on, Kiyo, we've made it to the classroom, but you don't realize you're monologuing like an idiot.

Kiyo: I'm sorry Yuki, I'm just wondering what the school is hiding.

Shiro: As in the entrance ceremony, the worst ones are placed in Class D and the best ones are placed in Class A.

Kiyo:Yes, but let's put these aside for now and get into the classroom.
When we entered the room, we saw that half the classroom was full. I saw that my desk was next to the back window. Since my desk is in a very good position, I can observe my classmates during class. I saw Yuki talking to a girl with purple hair tied in a ponytail and a beautiful girl with strawberry hair. The same goes for Shiro. I saw him chatting with a boy with glasses, a serious-faced boy with purple hair, and an energetic boy with blue hair. I guess if I want friends I have to talk to them. I stood up from my desk and approached Shiro's table.

Kiyo: Nice to meet you, I'm Ayanokouji, Kiyotaka Shiro's childhood friend.

Shibata: Nice to meet you Ayanokouji, I'm Shibata so

Kanzaki:Nice to meet you, I'm Kanzaki Ryuuji

Hamaguchi: Nice to meet you Ayanokouji-kun, my name is Hamaguchi Tetsuya
After talking for a while, a woman in her 20s entered, but for some reason she was a little swaying. He slowly approached the podium and began to introduce himself.

Hoshinomiya: Hello my dear students, my name is Hoshinomiya chie. I will be your classroom teacher for the next 3 years. Ah, I drank too much last night.
He leaned on the table and started telling us about the S-system

Chie: So does anyone have any questions?

Shiro pov.
After hoshinomiya sensei explained the S-system to us, everything fell into place. As I was about to raise my hand to ask a question, Yuki preceded me.

Yuki: sensei "this month" you said we will get 100.000 points "every month" right?

Chie: I'm sorry but I can't answer this

Shiro:sensei you said "you can buy anything with points". So can I buy the S-system?
As soon as I asked this, Hoshinomiya sensei's eyes opened and he looked at me in shock. That means no one has ever asked him this question before. Kiyotaka looks at me like are you seriously going to do this?

Chie: Only you cannot decide this, the whole class has to decide because the points you will receive next month may decrease.

Shiro: Ah, I gave up on taking it, sensei, can I talk to the class instead?

Chei: Sure, come show your sensei something interesting. 

I slowly stood up from my seat and started walking towards the front of the classroom. 

Shiro: My name is Kazumi shiro. Now I will tell you about the s-system, please listen to me carefully. First of all, I noticed how the classes were positioned during the entrance ceremony. While Class A was listening carefully during the president's speech, 2-3 of the Class D students were listening to the president, the others were either sleeping or talking among themselves. This means that class A is the elites and class D is the flawed ones. When we came to the classroom, I noticed something. I saw 4 hidden cameras hidden in the corners of the classroom. 
Everyone raised their heads and started looking at the corners of the classroom.
