The Nya Nya Dance, often associated with the Vocaloid character Gumi and the song 'Megu Megu Fire Endless Night,' became a viral sensation on platforms like Nico Nico Douga and YouTube. The dance features a character performing rhythmic, feline-like movements to a high-energy beat, characterized by the iconic 'paws up' gesture. Over time, it transcended its original fandom to become a go-to template for expressing pure joy, hyperactivity, or simply being caught in a loop of catchy music. On the internet, it serves as a peak example of Moe culture, frequently used in 'edit' videos where various fictional characters are animated to perform the same adorable choreography.
