Rabou is a mysterious figure who first appeared in the manga special "Clash, O Ye Gods of Calamity" before showing up in the anime with a timeline that doesn't quite match his original story. He's frequently seen hanging around Nora, Yato's shinki, and he's got the unsettling ability to control Phantoms—something most characters can't do. Like Yato, Rabou is classified as a God of Calamity, though the two clearly have history together, and whatever happened between them left Rabou with a serious grudge.
What really sets Rabou apart is how indiscriminate he is about his work. He'll kill humans, shinki, other gods, Phantoms—literally anything—as long as someone wished him to do it. He doesn't have standards or principles about his contracts the way some gods do. It's all business to him, no matter how dark the job gets.
