『Caiman』

Caiman is a victim of a magic attack that has 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 the Hole, hoping to find the one who cast the spell on him and kill him to nullify it. By biting down on the heads of Sorcerers, a mysterious presence that lives in his mouth communicates with the bewildered Sorcerer, stating whether or not they are"the one". Caiman then spits them out and asks the Sorcerer to repeat the information to him. This is his only lead to finding his original identity. Caiman's immunity to magic and formidable knife skills make him incredibly skilled at battling Sorcerers. He also has the ability to regenerate his head, allowing him to survive lethal attacks such as decapitation. When not fighting, Caiman loves eating gyoza and frequently sends Nikaido's restaurant, The Hungry Bug, teetering towards financial ruin due to his reluctance to pay his tab. While his imposing figure frightens some, he is generally well-liked in the Hole. At the beginning of the series, he works part time at a hospital for the treatment of magic victims.
