I've been reading it lately,and I'm up to the 6th volume currently. It's very enjoyable and different from other series I've seen. Chrno in his 12-year old form is very cute indeed. =D I love Joshua too,he's such a sweetie up until the whole horns and Rosette starting her contract with Chrno thing. I still like him after that though. xD I also liked how the story took place in America,lots of series I've seen only take place in Japan,so that was an interesting take on the setting.
Anime,hmm,I only saw up to the Christmas episode. So I don't know much of what goes on there.
