The Butler, In Chinoiserie is Chapter 147 of the Kuroshitsuji manga.
Lau tells Ran-Mao that it is "time to hunt," and she seemingly charges at Ciel, Sebastian, Finnian, Baldroy, Snake, and Mey-Rin—in fact, however, Ran-Mao actually attacks the wall behind the group, breaking it down and revealing the entrance to Lau's "Shangri-La" behind it.
While leading Ciel and the others inside, Lau tells them that he heard that Scotland Yard is searching for them and promptly decided to help Ciel so that he would become indebted to him. Then, Lau says to his employees that they should bath and dress Ciel and his servants and prepare a meal for them as well.
They are dressed in traditional Chinese clothes, and at the dining table, Lau states that he is not helping them for free and will eventually make Ciel repay his debt to him before he proceeds to ask what exactly has even happened.
Sebastian tells Lau why they are currently wanted by the police and that they planned to go abroad for a while—their current destination being Germany. Then, Lau asks why they do not go somewhere where nobody will know them, for example, China or India. Lau adds that if they chose India, they could get help from Soma Asman Kadar and Agni after all, and if they chose China, he himself would be able to help them. He also suggests that, if they are already so far away, they could just start new lives and run from their old ones.
Upon hearing his words, Ciel suddenly stands up and, to the surprise of all, begins to gulp down the food and drinks on the table like a savage before he succumbs to his anger, cursing his brother for coming back after three years in which he acted as the Queen's Watchdog and did all the tasks that fall to an Earl. He rants about how everyone never noticed that he was a fake until the real one came back and then turned their backs on him. Ciel declares that he will not run and that while he may not be "Ciel," he certainly was "Earl Ciel Phantomhive" and he would definitely challenge his brother and get everything back.
Sebastian approves of his master's spirit—but remarks that his table manners are awful.
