Have you read the authors current series, Dai Dark? I've only read a couple of chapters so I can't say too much about how it compares to Dorohedoro, but...

I assume you've already read Blame!?

Maybe Dungeon Meshi?

My favorite manga of all time. It's up there with dorohedoro in terms of world building, imo.

Only downside I think, is there is no muscle-mommy like Noi.

If you haven't read or watched it already, Hellsing.

I love DhD immensely and got the same joy from it as when I first read Hellsing many, many years ago.

No matter what but every single Media after reading Dorohedoro looks pale. I love the randomness and chaos of Dorohedoro.

CSM closer but not enough.

I am currently reading Berserk and Vagabond but any suggestions will be great Thanks
