here's what i've gathered: the 'role' is a general term, the sexual demon is one of the roles. as explained before, his grandmother got a role that possessed her to destroy her home and his mother got a role that made her feel excessive hunger. so the sexual demon IS a role.
I'm confused because the preview said he gets possessed by a sex demon. But whoever is translating keeps saying it's the "role," which doesn't really make sense.
