A member of the Dragon Empery and older sister to Ping Hai. She places others first before thinking about herself. Her vessel's history seems to have made her a bit frugal, and despite not being a person in need, she insists on cutting costs whenever possible. Watching Ning Hai's frugal ways have made Ping Hai aware of spending and becoming courteous... or, at least that's what Ning Hai hopes Ping Hai will be in the distant future. Ning Hai saw the Joint Military Exercise as a valuable opportunity for Ping Hai to experience, so she sends Ping Hai instead of participating herself.
Ning Hai meets St. Louis, which sparks an unexpected relationship between the two.
