[(Perhaps surprisingly) Sebastian notices the strength of the punch. He's a demon, of course, and it takes a lot more than a human hitting him to truly injure him, but that doesn't mean that a punch, especially a pretty good punch, doesn't hurt to an extent. It hurts more than his master's weak little slaps, certainly.
He dutifully takes it without flinching: his head snaps to the side and he makes a quiet, unappreciate noise, but his feet remain firmly planted to the ground and he doesn't stumble. #thethingsheputsupwith]
