Not So Dead Mari || Omori au

The long black haired girl in a white nightgown stares at her dead asleep brother, all he does is sleep. He never leaves the house, and he always acts like she's not there.. it's not just him though.. but why? why are people treating her.. like a ghost? which she isn't! she isn't.. she isn't.

AU summary;
OMORI but in the pov of Mari, who's a wandering ghost in denial over the fact she's dead. She also has Mewo, hi Mewo.

Book contains;
swearing, mentions of death/ suicide, and some other stuff that could be triggering (?)
