Hi guys! This is like my fifth story about assassination classroom or mentions it. Hope you like it!

Nagisa's P.O.V

I was getting out of the house when.. " Nagisa where are you going~~~~" My older twin brother asked me. " I need to go to school! Remember, that I had to transfer to help the Enders." I reply and my brother nods. I leave.

Nagisa's Brother's P.O.V ( You will find out her twin brother's name soon~)

She is adorable! I wish I was in her class. I want to make sure that no boys are hitting on her. I need to keep my secret with them.

^At Class^

No One's P.O.V

"Everyone! We have a transfer student to help." Karasuma says. " Please be nice to her. If you don't, she won't hesitate to hurt one of you, actually she will hurt the most closes to her. Please come in and introduce yourself." Karasuma opens the door but no one was there. Everyone was confused. They were so focused on the door, they didn't know what was happening. They didn't know what was happening until six of Korosensei's tentacles went flying. " What! What just happened?" Korosensei and the class screams. 

They didn't get an answer until they heard a chuckle from the back of the room. The class turns to Karma, and he shakes his head. The class hears the chuckle again, and they knew it wasn't Karma because they were looking at him. " Come out! Stop acting like a scaredy-cat and come out! Stop creeping us out!" Terasaka shouts, angry. " Why are you ruining my fun, huh, Ryoma Terasaka?" A voice said from nowhere. Everyone's attention turns to the front, they found...

Guess who they found~ Also about the twin brother thing. He is in the story but he isn't going to be revealed as Nagisa's brother until the sixth chapter.
