Naka is a Sendai-class light cruiser personified as an energetic idol in Kantai Collection, the Japanese browser game launched in 2013 that later expanded into anime and other media. Her self introduction, built around the line Naka-chan da yo, became one of her most recognisable traits among fans because it sums up her stage performer personality in a single second. As Kantai Collection clips and fan edits spread across video and soundboard communities, the line was clipped on its own and reused whenever a cute, confident anime entrance was needed.
