I will send you a PM about Ghost Hunt 10. I don't want to post spoilers in a public visitor area. About how closely GH anime follows GH manga, I'd say pretty closely. The only things the anime left out were some minor characters. And more importantly, some conversational information dumps. The conversational info dumps are important for post-anime events which is why the anime didn't need them. But you do need to know this information to understand some of what will happen in volumes 10 and later.
Hello LKK sorry to bother you, but I saw that you read vol 10 of ghost hunt ...I just have to know what happened???? and do the previouse vol of the manga series go into more detail than the anime or was the anime a frame for frame. word for word retelling of the manga story??
