Lt. Kyon Hwa Kim serves as Helm and Communications Officer aboard the United Planets Space Force destroyer *Soyokaze*. She maintains a laidback demeanor, viewing her commanding officer as irresponsible and exploiting his lax discipline to wear non-regulated clothing instead of the standard uniform. This choice initially causes friction with the protocol-strict Lt. Commander Yuriko Star. Over time, the two officers develop mutual respect and appreciation for each other's strengths despite their differing approaches. Kim consistently keeps updated on fashion trends and works as a model during leave periods.

Kim joined the military seeking purpose in life, believing facing danger would clarify her future direction. Before service, she was engaged to Captain Odon Baek, former commanding officer of the UPSF vessel *Yunagi*, who died during his service. Kim eventually married another *Soyokaze* crew member, Nguyễn Hồ Minh. Her heritage is indicated as either Korean or Zainichi Korean, and her name references violinist Chung Kyung-Wha.

Throughout her service, Kim demonstrates professional competence in her duties despite her relaxed appearance, often seen reading magazines while performing responsibilities. Her development involves navigating crew relationships, particularly resolving initial conflicts with Yuriko Star through recognizing shared dedication beneath their contrasting styles, reflecting broader acceptance of diverse approaches within the military structure.
