Oh, is this the same creepy thing that faked Yoh's voice and was calling for Miko to come out of her house in chapter 51? Was that the "old man" all along and he can assume other's forms or voices? That's really bad...
I forgot about that but yeah thats totally possible it was it for sure, cause she was at home all the time and no other things chased her this nigth.
It was imitating someone she know and just left seconds ago like if that person forgot something at her home.
In paranormal stories and legends, yokais, ghosts or demons may need the person's consent to possess, haunt or come to her house.
Like u accepted it to be part of your life and it can do all it wants now.
Thats pretty terrifying cuz it almost got her if dad wasnt paying attention.
Damn I love author's writting!
