Who is Christophine Buckley from Don't Stop the Carnival and what is their importance?

Christophone Buckley is in charge of the Immigration office on Amerigo. She is described as a large, brusque woman, who is also very sensual. Her job is to locate and deport illegal aliens, thus, she and Paperman have quite a few dealings with each other. Buckley's main target is a young, pregnant woman from Neves, who works at the Gull Reef Club. Over time, Paperman convinces Christophine to leave Esmee alone, as the child she carries is also the child of a notaive Kinjan.
