Green's Recommendations:
Action / Horror
Blame!
More of an artistic journey than a story.
With little dialogue, the Manga is mostly just beautiful dystopian landscapes rather than a story, although there is a story, it is not a strong one. Standing at only 66 Chapters it's a relatively quick read, and well worth it for the way that it looks.
Tokyo Ghoul:RE
A continuation of Tokyo Ghoul, starting after the original Manga ends and does not follow the path of 'Root A' the second season of the Anime.
I highly recommend this manga as it is still ongoing and is action-packed, violent, gory, shocking and beautifully crafted. Although the first few chapters plunge us into a world we are unfamiliar with, the characters we once knew start to emerge from the depths of the story, back on to our pages.
