Alexander

A butler of the Devil royal family who graduated as the top class from the servant department of the Royal University of the Demon World. Also known as 'Gentleman's Gentleman.'

Alexander is a servant among servants who can handle any task perfectly. He has been taking care of Nelia and her sister since childhood. Some demons who don't know the circumstances may see him as a potential brother-in-law for Nelia, but in reality, he is attracted to men (although it's said that he may also be attracted to women at times).
He is also interested in Raito, but instead of pursuing him romantically, he tends to fantasize about Raito's relationships with other men, which is becoming problematic.
