...So, from what I can tell, Marisa tries to help by bringing a dirty plate to anon, only to realize too late that she left a trail of food; probably knowing mister's reaction, freaks out, and then gets hit for it, the hit in turn making her vomit. Which this guy will probably punish her for again.
For all we know it could be a ploy by Marisa Or she purposefully was too lazy to actually clean it and spilled the food on her way to taking more of mister's food.
Basically Marisa wakes up in a garbage bag and was being crushed by a trash compactor and was crying out for big sis, and there was a flashback of her eating bacon over rice with big sis, this above picture and a few others with oniisan abusing her and a few others. I forgot the exact sequence since it was drawn pretty slowly. So was it a happy yukkuri who dreamt of an abusive life in the end, or was it an abused yukkuri who dreamt of a happy life?
neither so far as i read it i think the marisa is never dreaming about anything, all that happen is in sequence except a few flash back of it's past abuse in the last page
