As we've learned from the most recent chapter, her character throughout most of this story is her character in the online game she plays rather than the actual her. The flashbacks are her online character's backstory rather than her backstory.
Her brother didn't want her to pass on to the afterlife, hence why he didn't join with the group of friends who wanted to pass on with her.
I am having trouble understanding is why that one room was full of those pictures of her towards the start of the story. Also she had the back story about being rapped, how did that come about then if it wasnt true? Also why wouldnt her brother have joined the group if he had the same goal in mind? And where did the wierd memories of her brother come from?! Im so confused...(╯°Д °)╯╧╧
