The concepts of shinigamis, demons, nuns with guns, London, and gore are not unfamiliar motifs presented in many different mangas. Granted, this story has all of these, but an underlying yuri-esque theme that is quite vague initially, but so worth the read. I'm happily reviewing for you my (currently standing) all-time favorite manga series, Teragrammaton Labyrinth, by Ei Itou. Loaded, figuratively, not literally, with action, gory scenes, demonic presences, and a girl wielding a scythe contribute to my undying love and recommendation for this series.
Publisher:
The publisher of Tetragrammaton Labyrinth is Seven Seas, a somewhat obscure (I think) company who double in licensing as well as original works. This series is part of their "Strawberry" yuri line, which has been, as of late, undergoing tough sales and times. Other examples of their work/licenses include Aoi House, Kashimashi, and Amazing Agent Luna.
