Kim was a mercenary serving aboard the fast cruiser Ariel during the Tau Verde Ring war as part of the Oseran Mercenaries. The crew of the Ariel defected en masse to the then-fictional Dendarii Free Mercenaries after being captured by Miles Naismith, and Kim received the rank of trainee. Kim died during the Dendarii operation that captured a Pelian-held rare metals refinery and the Oseran pocket dreadnought Triumph.
