Agaliarept is a high class demon who is an otaku and a moe expert, who keeps a huge collection of bishōjo games and anime in his lair, and doesn't want anyone to disturb him when he's watching or playing them. He is the First President of the Underworld Dark Moe Anime League. He has a masochistic maid, named Fermi, who is loyal to him and enjoys being punished by her master's lightning bolts.
