Cerberus

A demon known as the watchdog of the underworld. He wears two sentient dog puppets—'Mimi' and 'Coco'—on each hand, launching them to gather intelligence across the field. Throughout the story, he operates alongside Azazel in the human world, tracking down the stolen 'Key of God.' While his demeanor is cheerful and easygoing on the surface, he harbors a cold, calculating side that emerges whenever his objectives demand it.
