Closure

Closure is an NPC in Arknights who runs the in-game Store. She also plays a story role in the Heart of Surging Flame, Darknights Memoir, and Operational Intelligence side stories, and briefly appears in the Ancient Forge side story. Born Ada Church, Closure was one of the founding members of Rhodes Island, acting as R.I.'s chief engineer and is responsible for maintaining the R.I. landship's facilities as well as the creator of Castle-3, Lancet-2, and THRM-EX. Closure has a mischievous personality and enjoys making jokes and pulling pranks. She appears to be rather lazy, preferring to delegate tasks to others instead of handling them herself. However, without her R.I. would be incapable of functioning. Closure is a vampire Sarkaz who can see well in the dark, but whether she is hematophagous and/or nocturnal remains unknown.
