Let's Go! Onmyouji originated from a promotional music video for the fighting game Shin Gouketsuji Ichizoku: Bonnou Kaihou, released in 2006. The video features an absurdly catchy song and a synchronized dance performed by the character Doman Ashiya, a Buddhist monk, and several assistants. It became a monumental hit on the Japanese video-sharing site Nico Nico Douga in early 2007, serving as one of the platform's first viral sensations. The meme is typically used to represent unbridled joy, chaotic energy, or a spiritual ritual to clear away negativity. Its longevity is attributed to the bizarre juxtaposition of traditional Japanese spiritual themes with high-energy J-pop choreography and early 3D animation.
