Shirobako is a 2014 anime series from studio P.A. Works about five friends working in the anime industry. Ema Yasuhara, a key animator in the show, became a fan favourite for her earnest personality and a brief dance sequence that animators and viewers clipped and shared online. The moment spread through anime edit communities and soundboards because it was short, expressive and easy to loop. It remains in use as a shorthand for cheerful, slightly embarrassed energy in fan videos.
