I'm looking for an fantasy inseki novel; but can't remeber its name. It had a guy that could heal, as well as had a spa/onsen pocket diminsion. I keep serching for it but there are other anime/manga/novels that isn't the one I read that keep coming up in google and other search platforms. seems to be rather buried on the web.
