Devils Line

Both animes are suited for more mature audience, one is mainly for it's violent scenes, and the afterimage of the death, while Devils Line is mainly more mature for it's hints of adult actions. Devil's line is also quite violent in terms of certain episodes, so for action, horror, and a tinge of anime, watch one or "another." :P
P.S. Sorry if this recommendation is bad, it's my first one, and it's a bit hard for me to summarize the differences that got me into both animes...
