I plan on buying it. And I really look forward to seeing season 2 come out as well. It is my favorite anime yet. I love it more than dragon ball and I really love dragon ball!
Glad that you liked it. However, unfortunately there are no plans for a second season of Ghost Hunt. It didn't do so well in the sales department, and it's been many many years since then, so I wouldn't get your hopes up.
Never fear, though. There are plenty of other horror/suspense anime series here on FUNimation to enjoy. :)
