Supernatural and school life I know there was maybe another one but I can't remember. But I did remember the guy wish that the demon would become human and their bodies are weirdly connected like if he gets hurt the demon could feel his pain something like that.
Found it :)

Wow thank you thank you so much for your help and finding it I really appreciate it:) Sorry it took me so long to respond today's my only day off from work.
Hello I read this manga a few months ago I only read the first chapter the only thing I can remember is. This one guy went to a convenience store but he saw this guy he knew from school I don't think they were friends but he recognized him and for some reason he had a piece of paper a knife and a chicken in the middle of the road and weirdly the guy that went to the convenience store summoned a demon. The chicken got run over by car and when he summoned the demon he asked the guy to bring the chicken back to life. And then he wish the demon was humans so he had a demon tail and it turned into a tattoo. I'm sorry I'm all over the place I hope somebody can recognize this thanks.
