“I’m aware I never mentioned that part when I was introducing myself as your new butler, however that’s because I didn’t think it necessary.”

Of course he didn’t think letting you know he was a demon was necessary. Not many people want demons handling matters in their houses, you see. But Sebastian wasn’t any demon, he was a very seductive one. Meaning, he could slip out of this dilemma with a few words of persuasion — or so he hoped.

Perhaps if he showed you how good of a demon butler he is you’d focus less on the demon part and more on the beneficial part.

“I apologize, but I assure you—demon or not—you won’t find a better butler than I.”
