Dorohedoro is a dark fantasy manga and anime set in a post-apocalyptic city called Hole, where sorcerers from a parallel world experiment on the residents. The story follows Caiman, a man with a reptile head and no memory of his past, who hunts sorcerers with his friend Nikaido, hoping to find the one who cursed him and restore his human form. Readers enjoy it for its gritty, unpredictable world, brutal but humorous action, morally grey characters, and a deep, sprawling plot that unravels mysteries about both the sorcerers and the victims of Hole.
