-High School AU-

{A's} town was known for often having huge crimes in it. But this one,that happened barely one day ago, was...kind of special. Most of the walls of their school have been painted entirely with quite big graffities. Worst part of it? No one knew who exactly did it since on the school's security tape,the responsibles were completely hidden by their clothing. Thus making them unrecognizable. The police was currently trying to know who they were. After that accident,every students were strictly told not try to make an investigation on their own and that the police will take care of it.

Despite the order, {A} and their sibling/friend {B} still decided to lead their own investigation of it.  It looks like they didn't want to understand that the responsibles could be very dangerous.

Who's {A}?
Who's {B}
