her friend that likes to eat alot is actually an evil person well back when she was young but she wanted to change so every time she saw somebody in need of help she came to assist them she wanted to do better but since gluttony is a sin she started attracting more spirits. also those spirits want her because they want her as an sacrifice because of her aura and they are helping the other girl because she can see them and they trying to use her as a way to lure the other girl in the shrine. But the pigtail girl would hang out with the evil dude and shes gonna betray her friends. she was jealous of the fact they were better than her and so the evil man saw that and took that as an opportunity to use that her lol
also the teacher starts liking the black hair girl since he notice his life was getting better cuz of her

i dont expect this to actually have a decent plot... now im super curious about the shrine girls.. someone please spoil to me
