Decadent

Although Decadent is a world renowned supermodel, they're very aloof and don't often socialize out of obligatory social outings and work.

They're a grem of few words, but when they do speak its straightforward and to the point. They don't really like small talk.

People's first impression of them is, frankly, that they're a stuck up bitch. And yeah that might be true, but in secret they're also a very generous benefactor towards organizations that work to liberate, relocate and rehabilitate those who were outcast and hurt by society. 

In reality almost all their money goes towards those goals, but they go through great lengths to keep that a secret.
