Lin's full name is Lin Yuhsia, however she simply chose her first name to be her codename when she joined Rhodes Island as an Operator. Lin holds many positions within Lungmen, including being guest lecturer at one of Lungmen's universities despite her true shadowy background. Lin is usually very calm, but prone to outbursts of annoyance and anger if pushed.
