Lau and Ran Mao | Black Butler

Lau is a tall man with short black hair and dark brown eyes, which he almost never opens. Additionally, he has a blue dragon tattoo on his left arm.[11][12]

Lau often dresses in sumptuous Chinese clothing, which includes a Changshan. He tends to keep his hands clasped and hidden in his "capacious" sleeves. Within said sleeves is a needle, which he describes as "an instrument of oriental medicine."[13]

Personality

Lau is a placid, even-tempered individual who is apt to make facetious remarks[15] and act as though he is aware and well-informed of an important matter, only to later reveal that he is, in truth, clueless;[16][17] Sebastian Michaelis believes that he simply chimes in whenever "he thought it appropriate."[18] Moreover, he is frequently accompanied by the female attendants of the opium den he manages. He refers to his personal assassin, Ran-Mao, as his sister, although they are not related by blood.[19]

Lau is an enigma; Baldroy once mused that he is uncomfortable around him, since he can never tell what he is thinking.[20] Furthermore, Lau is, for the most part, unprincipled and mercenary. He curries favor with those he thinks will allow him and his business to advance and those who are ambitious, such as Ciel Phantomhive. Ran-Mao is an attractive young woman of Chinese descent with large golden eyes and long jet-black hair with square bangs. Her hair is arranged in thin braids and twin buns shaped like cat ears, and ornamented with a pink peony and a golden tassel on the left bun.

Ran-Mao often wears a short lavender and black cheongsam, which is decorated with dark pink petals, with a dark blue cropped jacket and a Western corset[6] over it. She also wears thick black stockings when she goes out,[6] black ballet shoes, and gold anklets with bells.

When performing her duties as Lau's personal assassin, Ran-Mao wields two chuí (hammers or maces); the chuí are gold, blue, and maroon in color, and adorned with a blue tassel on top. A single swing of the chuí can break pavement.[7]Ran-Mao is a mostly emotionless, taciturn individual who hardly ever engages in conversation. She is deeply loyal to Lau; she accompanies him wherever he goes and generally acts only when instructed by him.[8] Although she is not related to Lau, he refers to her as his sister, given that they have known each other since they were very young;[9] he once described her as a "pampered child."[10]

Ran-Mao is flirtatious. At Lau's behest or suggestion, she will attempt to seduce others, such as when she flirted with Georg von Siemens at one of Ciel Phantomhive's parties[10] and Baldroy.[11]

Ran-Mao, a highly skilled martial artist, possesses formidable strength and speed.[12] She has no qualms about using violence to extract information or to defend herself.[13]
