I'm watching Dorohedoro. It has 10/12 episodes currently aired.
The story takes place across 2 worlds, both of which are vastly different than what could be considered "normal."
The Sorcerer's world is full of bizarre mechanics, ceremonies, and operates under the reverence of devils.
'Hole,' the world of humans, is plagued by the effects of the Sorcerer's world, where even the dead are reanimated from their world eking magic, and it has become the norm to meet individuals with strange mutations who have been experimented on by sorcerers.
The main characters are a Lizard-headed man Caiman and his friend and restaurant owner Nikaido. Caiman has no memories of his past, and seeks for find out who he was and to regain his human face.
It's extremely violent, cute, and colourful. I highly recommend it if you are 18/+(or 19 if you live in Korea).
