" Hey Karasuma, who was screaming, also it is your turn to teach the students." Irina said. I nod then leave.

With the class

I wonder who was screaming? They thought while changing. They shrug it off.  During P.E. the students realize that Karasuma was in a daze. " Excuse me Karasuma, are you okay?" Isogai asks the emotionless teacher that was in a daze. As if he was broken out of a trance, his eyes snapped open. " I was just thinking about something. Class is dismissed,"

Meanwhile in A-Class

" Nagisa, can you please come up and explain this question?" The teacher asks the blue girl. " Hai!" Nagisa walks up to the front and writes down the working out in the simplest form at the speed of Mach 10, while saying out what the equations mean. Everyone in the class stared in awe.

After School~

"Excuse me, Nagisa, can we walk with you home, since we live near you?" Nagisa hears someone say, she turns and sees Ren and Gakushuu. I nod and get my things. When the trio get to the gate of the school, they were stopped by a certain red head and raven head. 

Nagisa's P.O.V

"What do you want?" I snap at them, taking my katana out of nowhere. I felt a hand on my right shoulder, I turned to Ren. He shook his head. I sigh. I start walking to my house, I felt four people following me, two invited and two uninvited. I sigh again. "Karma and Isogai. Why are you following us?" I ask turning a certain angle. I hear Karma growl and Isogai mutter something to Karma. Me, Ren and Asano leave to my house and split when we got to our houses.
