Help title

I've been looking for this manga for forever and already forgotten what it is mostly about. But one particular scene comes to mind and that'a all I can remember.

So the main character comes to a farm(not necessarily fields but rather more of a country town farm with barns and such) the main character meets a family?(Actually I'm not even sure anymore) I just remember the guy turns to be like zombie-like or the dead and the main character was attacked. So I think the main character is somehow an exorcist of sorts. The sister(?) saw her brother(?) turned to monsterlike but somehow ended up blaming our main character in the end.


Sorry its really been so long I barely remember the scene anymore. Just bits and bits I remember seeing an axe too.

But any help is welcome, I'm having a hard time looking for it even if I attach exorcist on its name and such.

I also remember the main character riding a train(or something train-like) but got left behind too and thats how he found the farm.
