The Butler, Mesmerising is Chapter 150 of the Kuroshitsuji manga.
As Lau wants Ciel and his servants to work for him in exchange for giving them shelter in his opium den, Sebastian practices his seductive technique of luring in new customers while Ciel tries to be a waiter. Lau is impressed by Sebastian's performance as a "corrupting influence" and asks him if he wants to work permanently for him; Sebastian declines. On the other hand, Ciel proves himself absolutely incompetent at being a waiter, much to Lau's amusement.
Then, Ciel, Lau, Ran-Mao, and Sebastian retreat into a private room to discuss their plan of how to proceed. Before they begin, however, Ciel wants to know what the people are saying about him, and Lau shows him various newspapers which all illustrate Ciel as the mastermind behind the Sphere Music Hall murders.
Lau asks why Ciel does not simply storm into Phantomhive Manor with his servants and kill his brother, but Ciel replies that it would be rather troublesome because of Undertaker. Lau then asks what Ciel's next move is.
Ciel tells the others that he believes that "Ciel" is still nothing but a Bizarre Doll, a significantly improved one compared to the ones they have encountered before, but nevertheless still just a Bizarre Doll—and as one, "Ciel" requires large quantities of blood to function. He and Undertaker collected these quantities with the help of the Sphere Music Hall, but it was shut down and "Ciel" cut off from his apparent "only" way of collecting the blood he needs. Knowing himself and his brother, Ciel is certain that there must be more establishments like the music hall. Therefore, his first move is to destroy all of his brother's lifelines.
Ciel orders Lau to look into reports of human trafficking, missing persons, and underworld goings-on involving many people; and he orders Sebastian to look into new trends, establishments, and large group events. Then, both Sebastian and Lau bow in front of Ciel and say "Yes, My Lord." Even Ran-Mao curtsies.
Sebastian and Ciel are surprised, and Lau states that he always wanted to try it out as it sounds "so cool."
