While Seung-ah and her mother were enjoying family time in their home city's park, the Covenant invaded Reynif. Seung-ah's mother was killed by Covenant infantry, but not before she ordered her daughter to hide in the park's pavilion building. Several hours later, Seung-ah was found by Dominic-094, Thomas Prado, and  Cynthia Sinquefield, who were also stranded in Saeloun Seoul. The SPARTAN called for evac, but a phantom arrived at the park before any UNSC transport could, and deployed. Dominic-094 told Sinquefield to take Seung-ah deeper into the building, while he and Prado would fight the elites.

Seung-ah is best known for her ability to keep almost all wounded allies alive long enough to receive proper medical attention, regardless of how terrible the injuries are. Not only is she able to temporarily treat wounds to the best of what is possible, but she verbally gives incapacitated allies the will to live. Those who have been treated by her describe her as "an angelic, reassuring presence" or "giving off a soothing aura."

Like all Gamma Company SPARTAN-IIIs, however, Seung-ah is unrelenting to her enemies when provoked, due to the 009762-OO drug that was injected into her during, and she must take regular doses of 009127-PX and 009927-DG to prevent uncontrollable aggression.
