The one who kill her aunt... a part of me wants to say Mion did it to save her... the way she acted about the whole thing don't give this though but she did seems like she can do something about it for a little bit... how she did it? the guy who killed her was someone from her family who was told to do it to live, her family have the drugs they use for demonic things and lots of other type of drugs so forcing him to do it is something easy, another part of me is thinking that the coach has done it... he is a doctor and giving this guy some drug type and leading him to the aunt is not very hard... why? he wanted Satoko and Satoshi to be free of them... and i also believe he is the director which we know the Mion last ge could have been trying to cover for... we also know about the dead bodies moving... something that require a drug that no one knows about... a drug that could make the body move and be under control... something the director could have been using... why is he doing all of that? something grand is awaiting but i got no idea what it could be @_@ i can go and reach some theories but they will not hold weight if i just drop them out of a hunch... hmmm @_@
