Dorohedoro

In the lawless district known as Hole, sorcerers from another world use its residents as guinea pigs for their twisted magic. Caiman is one of those victims—left with a reptilian head and no memory of his past, he’s now on a brutal quest for answers. To reclaim his true face and forgotten past, he and his partner Nikaido hunt sorcerers, hoping to uncover the truth behind his transformation.
