At first glance, Sebastian is the epitome of a
perfect, genteel Victorian butler. He completes every duty with ease and to
very high standard, to the point where he often ends up having to cover for his
colleague’s mistakes – there is nothing that he cannot do. However, in reality
Sebastian is a demon who formed a contract with Ciel and he aids his master in
all missions with an efficient and frequently cruel nature. Despite his fierce
nature as a demon, Sebastian has a soft spot for cats since they are cute and
never complain about useless things.
