Granblue Fantasy began as a Japanese role-playing game released by Cygames in 2014 and later expanded into anime and manga adaptations. Yggdrasil appears in the series as a primal beast often shown in a youthful, gentle form, and fans clipped her cheerful vocalisations as they shared favourite character moments online. The sounds spread through fan edits, streams and soundboards as a shorthand for innocent happiness, especially among players who recognise the character instantly. It remains used because few other game clips convey uncomplicated delight so quickly.
