Also known as: 応急修理要員
In Kantai Collection, a Damage Control Crew, or "DameCon" for short, is a type of single-use equipment that prevents a shipgirl from sinking from extreme damage.
In KanColle itself, they appear as a trio of girls wearing construction Helmets, work Jackets, Pleated Skirts, and Shoes. Each one has a different hair style, but they include Grey Hair, Brown Hair, Low Twintails, Ahoge, Swept Bangs, Hairclip and Short Hair. They carry planks of wood, tape, and a Hammer.
In fanarts, only a single girl may appear, and there's no guaranteed traits, although the helmet and hammer are common traits.
