there's a show for it?
Yes and they fucked it up reaaaal bad.
The anime started running 7 April , 1 episode out so far, releasing every Saturday night. I liked it. The art is good and the voice acting suits the characters. As long as they follow the manga's plot it should be amazing. ^^. https://www.masterani.me/anime/info/2825-devils-line . If there is a subbed release DVD pack available after this season I'll order it online and hope it reaches my country safely.
Seen the first episode. Manga is way better.
