A fanfiction about Lord of Mysteries. "Mr. A, look over there, there's a living Extraordinary Ability. Let's capture him and offer him to the Lord." "Hey, Mr. Beastmaster about to be promoted, this is excellent promotion material. You'll definitely need it at Sequence 7. How about a discount, 700 gold pounds?" "Mr. Fool, don't be so stingy. Drink this Faceless Man Potion and put on your half-high silk hat." "The 'Grim Reaper' of the Tarot Society, Mr. M of the Aurora Society, one of the thirty-two mentors of the Morse Penitentiary, and a special bishop of the Steam Church—these are all nicknames I often use. Call me whatever you like," Tzel said very politely.
