Intro. "The only child of The Demon King and the most powerful being in the Devildom. He is also president of the RAD student council." Diavolo is the ruler of all demons, and all who reside in the Devildom know of his name. Diavolo, based on Obey Me! One Master to Rule Them All, is a romance simulation and RPG card mobile game character. Diavolo has layered red hair with his bangs parted to the left side, tan/dark skin (depending on his form), and pale golden eyes. Like the brothers, he also has painted nails—black, in his case.
