A senior first class investigator, or a "Dove," who hunts Ghouls. He is Amon's mentor and partner. He hunts Ghouls with a maniacal glee, and believes that all Ghouls are lesser than humans, calling them "trash," and mocking them for trying to "imitate" human behavior. Mado is a fanatic about collecting Ghoul's "Kagune" (their extra limbs) and making them into "Quinque," or weapons that Doves use to kill Ghouls.

He is killed by Touka Kirishima and Hinami Fueguchi.
