Although the Louche Devil stays out of the crowds, minding his own business, it's obvious he's not human. Worse, there's an air of menace around him. People give him a wide berth. You'll need to work on his demeanour a bit more.
The Louche Devil takes your advice and doesn't draw attention to himself. And no one notices him. You observe his demeanour for a while, and from a distance, he could indeed be taken for a human man. It is a start.
