Devas is a small town in the magic world. There is not much to talk about the place, since only the Smoke Shop of Shaitan was presented, and eventually never talked about the place again.
Yet we can appreciate the ancient architecture of the landscape, not having the typical elements of the prominent cities or small towns in the sorcerers world, but rather an adobe and mexican elements of the presented building.
The smoke shop owned by Shaitan where Dokuga slaughtered everybody in search of healing magic is located here. Disguising as a girl to sneak into the mansion, Dokuga used his poisonous spit to kill every person downstairs, and the rest of Shaitan's workers with sheer brute force and his combat knives, after that he stole all the heal-type smoke in order to cure Tetsujo and Ton, severely wounded a month prior these events by Curse.
