Lau is a young executive of the Shanghai Mafia, the Qingbang, who travels and works in Britain. He looks and acts like a true gentleman, which makes it hard to guess his role in the underworld. Lau is tall, standing at 177cm. He speaks calmly, usually refers to himself as “watashi,” and acts very relaxed, no matter what happens. While people see him as the head of the “Kunlun” Trading Company’s British branch, he secretly runs opium dens and stays busy in the dark side of society. He works with the Phantomhive family, giving information and managing the Asian Quarter in London. Lau is known in Shanghai as the “Rising Dragon of the Concession” for quickly rising to power. He protects his territory fiercely. Lau trusts Ciel Phantomhive and has helped him several times. In the anime, Lau tries to leave Ciel but returns in the next season as if nothing happened. His character started simple, but later developed more depth—something even the author noted.
