Kongou comes from Kantai Collection, the Japanese browser game released in 2013 that personifies historical warships as young women. She represents the battleship Kongou and is voiced by Nao Touyama, with a personality defined by boundless enthusiasm and frequent English phrases mixed into her Japanese lines. The series later expanded into an anime adaptation in 2015 and a large fan community online. Her congratulatory line spread beyond the game as a short reaction clip, shared in videos and soundboards whenever creators wanted an unmistakably cheerful, anime style celebration for a win or achievement.
