Sotetseg is the main villain of this story in particular. He is one of the Masters of Darkness, perhaps one of the most jovial of the group. He finds everyone and everything around him to be attractive, even complimenting and, to a degree, even flirting with our heroes. He seeks to stop the youngest Servants from going into hiding, stalking them until the moment is right to attack. He is hardly ever mean, always complementing those around him, though in a very seductive and, often times, inappropriate way. He doesn't really hold back his desires or his thought process.

While not necessarily effeminate, I don't see Sotetseg as creepy either. He is very well kempt and any other person would view him as charming, if they didn't know the motivations behind his actions and words. He is handsome and his voice, to an extent, should reflect that he knows that he is, without sounding cocky. Very confident and smooth, very suave. A Hispanic accent is favored, but not required.
