Ayanami comes from Kantai Collection, the 2013 Japanese browser game where World War II warships are reimagined as anime girls called ship girls. She is based on the Fubuki class destroyer Ayanami and is known for her earnest, hardworking personality. Short voice lines like this one were clipped and shared on anime soundboards and in fan edits as the game and its 2015 anime adaptation spread internationally. Fans still use the Yarimashita line because it captures her proud, diligent character in a single instantly recognizable phrase.
