I really hate to admit this but uh.. I am so confused! So the shrine doesn't exist? How could grandma tell? Did MC accidentally make a contract with some demon?
I'm thinking this new guy is the one who sent Granny the photo, and I don't think he's a good guy since she mentions she has to get back before it's "too late"
On page 23 on the image on the phone that Thing looks like it's eating something like one of the shrine maiden perhaps could someone tell me what is going on?!
