Caiman
A reptilian-headed amnesiac hunting sorcerers in Hole to recover his memories.
Caiman is the amnesiac reptilian-headed protagonist of Q Hayashida's manga Dorohedoro. Working together with his friend Nikaido, he hunts sorcerers in the polluted slums of Hole, hoping to kill the one whose magic erased his memories and gave him a reptile head. His only lead is the full-size man who lives down his throat: by placing a sorcerer's head inside Caiman's mouth, the man's head will slide up and verify if they are responsible. Caiman also works at a community hospital for magic attack victims, and spends much of his free time eating gyoza at Nikaido's restaurant, The Hungry Bug.

Lore & Background
Caiman is a victim of a magic attack that left him with the head of a reptile and no memory of his original identity. He works with his friend Nikaido to hunt down sorcerers who enter Hole, hoping to kill the one who cast the spell on him and nullify it. Caiman's immunity to magic and formidable knife skills make him incredibly skilled at battling sorcerers. He also has the ability to regenerate his reptilian head, allowing him to survive lethal attacks such as decapitation. When not fighting, Caiman spends most of his time working at a hospital for magic victims and eating gyoza at Nikaido's restaurant, The Hungry Bug. The news of a lizard-man killing sorcerers—one with cross tattoos and magical resistance—attracts the attention of the de facto ruling sorcerer En, who believes Caiman is tied to the Cross-Eyes Gang.
In Their Own Story
Caiman wanders Hole searching for the sorcerer whose magic erased his memories and gave him a reptilian head. Assisted by his friend Nikaido, a restaurant chef who runs The Hungry Bug, Caiman's only lead is the full-size man who lives down his throat: by placing a sorcerer's head inside Caiman's mouth, the man's head will slide up Caiman's throat and verify if they are responsible. Getting a job at a community hospital for magic attack victims, Caiman works with Drs. Vaux and Kasukabe to reach the sorcerer's world and uncover his past. The news of a lizard-man killing sorcerers, one with cross tattoos and magical resistance, attracts the attention of the de facto ruling sorcerer En. En believes Caiman is tied to the Cross-Eyes Gang, which subjugated humans and lower-class sorcerers, and whose leader almost wiped out En's crime family before disappearing. En sends his cleaners, Shin and Noi, to kill Caiman with two low-ranking sorcerers: Fujita, who seeks revenge as Caiman murdered his partner, and Ebisu, who has amnesia after Caiman accidentally tore her face off.

World Building and Setting
The series takes place in a post-apocalyptic urban setting, spanning three realms: Hole, an ungoverned human favela megacity, heavily polluted from magic waste; the sorcerers' world, an ethereal, Gothic class society, controlled by crime boss En; and Hell, the afterlife of all sorcerers, ruled by demons presided over by Chidaruma. Despite similar outward appearance, humans and sorcerers are two distinct species; the latter were manufactured by Chidaruma in his realm, whereas the former occurred naturally in another. Sorcerers can also use magic through a circulatory system, which disperses a black smoke that gives them distinct powers. Stronger and rarer powers are highly prized, to the point of directly affecting social status. Humans are forced to live in the slums of Hole, subject to unprovoked sorcerer violence and overwhelming magical pollution, whereas sorcerers live and travel freely between realms using conjured doorways.
Supporting Cast and Alliances
Caiman's closest ally is Nikaido, his best friend and owner/chef of The Hungry Bug. She found Caiman after his initial transformation and helps him hunt down Sorcerers. She is secretly a Sorcerer herself, living in hiding due to the desirability of her magic type, and maintains contact with a devil named Asu. Professor Kasukabe is a scientist who has studied Sorcerers for decades; he is approached by Caiman and Nikaido to use his artificial door to the Sorcerer's world. He is frequently seen with his sidekick, a giant humanoid cockroach named Jonson. Dr. Vaux runs a hospital catering to those altered by Sorcerers and employs Caiman as an assistant. En, the leader of the En Family, sends his cleaners Shin and Noi to kill Caiman, along with low-ranking sorcerers Fujita and Ebisu.
