First introduced as a bored, yawning prostitute in Silas’s “Heaven“, the Las Cruces whorehouse where he hosts Isaac, Yu quickly reveals herself to be much more. She is the leader of a gang of rebels within Silas’s Las Cruces gang. Meeting in secret, "The Money Boys" want “Fuqiang“, wealth and power. When Yu pulls her glossy black wig back to reveal she is bald, her co-conspirators realize that she is sick. She is dying, in fact, from the effects of Oasis’s harsh environment. She believes that Silas has the magic that could cure her, and she needs it now.
