Back From The Dead?!?!?!?

Rin looked out the window, daydreaming about her family. She had completely missed everything the teacher had said, until she said something Rin thought she would never hear.
Teacher: Class we have a new student.
A thin girl with long black hair walked into the room.
Teacher: This is Mariah Korinama.
Rin turned around and stared at the girl. She stood up.
Rin: That's impossible!!!
The teacher glared at her as she shouted.
Teacher: Miss Korinama sit down please!
Rin: She is not Mariah Korinama!!! My sister is dead!!!!
The teacher looked taken aback. Mariah tilted her head to the side and grinned.
Mariah: Long time no see older sister.
Rin: You are not my sister.
Mariah: Do you really believe that?
Rin clenched her fist and looked at the girl.
Rin: My sister died in a car crash when I was little.
The students sitting around them looked back and forth between the two. They had heard that Mariah had been Rin's twin sister though they looked almost exactly alike except for their hair color. Ilanna stood up and gripped Rin's shoulder and whispered something to her. Rin pushed her back.
Rin: That is not Mariah!!!!!!
Mariah laughed.
Mariah: There is no denying the truth older sister.
Rin realized something. There was something strange about Mariah. She laughed lightly.
Rin: What kind of sick game is this really?
Teacher: That is enough Miss Korinama!!!!!!
Rin: Shut up!! Stay out of it damnit!!!
Mariah laughed.
Mariah: Still the same weak little girl who can't except the truth.
Rin smiled.
Rin: Take off the mask Moka.
Mariah laughed.
Mariah: Damn I thought I'd get away with it longer.
She pulled off the mask and took off the black wig to reveal short strawberry blonde hair.
Mariah/ Moka: How'd you know?
Rin: Next time you want to trick someone don't act like thier dead relatives.
The teacher looked between them.
Teacher: Will the two of you please explain?
Moka bowed slightly.
Moka: Sorry for the deception ma'am. You are correct in me being the new enrollee, but my name is Moka Kurosutchiro. The correct paperwork is in the office, the principle agreed to let me pull this prank as I have not seen my friend in many years.
Teacher: Just please take a seat.
The teacher sighed and turned back to the blackboard as Moka took a seat next to Rin and Ilanna. Moka smiled and whispered quietly.
Moka: Almost had ya.
Rin and Ilanna: Not likely.
Teacher: Ilanna, Rin, and Moka be quiet or I'll send you to the principles office.
Rin, Ilanna, Moka: Yes ma'am.
Moka: Jeez she's strict.
The three of them laugh.
Teacher: To the principles office now!!!!
The girls walked out of the class still laughing arm in arm.
