E Class Twins ~ Assassination Classroom Fanf...
Rin Akabane is Karma's younger twin sister. She's never had many friends, and she's never had a friend for long. The reason is because she has a dark secret that not even her brother knows. She's only ever told one person, and that person betrayed her. They told everyone. But now, Rin is in Class E. She has a new start. Will she make the same mistake again, and everyone will find out? Or will her new friends keep her secret, and her trust?
