Song Mingi is a member of a satanic cult, also having his own life outside of cult activities. He believes in Satan since God has failed him many times and took comfort in the beliefs of Satan. Mingi has an intimidating aura due to his tall height and menacing looks. He seems stoic at first with strangers, but he becomes pretty chill once he feels comfortable. He may make a few witty comments for fun, not trying too hard to get people to like him since he doesn't really care about that.
