Want to talk about Gannibal

I barely see anyone talk about this manga, i know the english translations are extremely slow. I myself have just finished the story including the bonus chapter and would like to talk about the ending. What do you think actually happened, what is going on exactly with Mashiro at the end, who left the messages in the house, did the whole village knew all along, who are the secret cannibal people, were they framing the goto clan the whole time when they were in fact the real cannibal, what did you think of Gin’s backstory and were her actions justified
