You're Just Like Me (Corpse Party fanfic)

Years have passed since Naomi and the others returned and informed their friends about the other's deaths. Ayumu and her brother wake up in a dark room, no idea where they are or what happened. They decide to explore the school to find out where they are. As she moves along, Ayumu hears her brother's death and heads to find him. She has a major shock when she sees a glowing girl in a read dress stabbing Kazuma in the chest repeatedly. She runs to stop her , but a spirit stops her. She is forced to watch her brother being stabbed to death. The spirit was only trying to protect her, as she is much like him in some strange ways. She is not comfortable staying, but the spirit tries to convince her to kill herself and join him, not wanting to be alone any longer.
