I started this manga now, and damn - I think I'm going to be attached to the storyline. I like the mild gore and bloodshed. The elf is the perfect balance for such a serious chapter in my opinion
edit: I forgot to mention the artwork. Phenomenal. Gatts reminds me of Zoro (the character physique and sword handling). Both their personalities are on similar lines. The artwork is absolutely infatuating. I love it.
