Series is currently running in Japan, with Netflix streaming planned for the future
The Dorohedoro anime may be in Netflix jail at the moment, but it's currently running in Japan and adding new cast members as it airs. The latest to join the cast is a veteran of the industry, with Shigeru Chiba (Kuwabara in Yu Yu Hakusho, Buggy in One Piece) hopping in to voice Chidaruma.

Dorohedoro originally ran in Ikki magazine before moving to Hibana and then Shonen Sunday. Q Hayashida kicked it off in 2000, and the series was collected in 23 volumes. Viz Media publishes it in English and describes it like so:
In a city so dismal it's known only as "the Hole," a clan of Sorcerers have been plucking people off the streets to use as guinea pigs for atrocious "experiments" in the black arts. In a dark alley, Nikaido found Caiman, a man with a reptile head and a bad case of amnesia. To undo the spell, they're hunting and killing the Sorcerers in the Hole, hoping that eventually they'll kill the right one. But when En, the head Sorcerer, gets word of a lizard-man slaughtering his people, he sends a crew of "cleaners" into the Hole, igniting a war between two worlds.
