Shigure Ui is a renowned Japanese illustrator who debuted as a Virtual YouTuber in 2019, but her meme status reached legendary proportions with the 2023 release of her music video 'Loli Kami Requiem.' The song's catchy rhythm and the self-deprecating 'Ui-beam' dance became a massive sensation on TikTok and YouTube, garnering tens of millions of views. The meme typically highlights her judgmental or playful persona, often used to humorously call out 'degenerate' fans or celebrate the high-energy choreography of her avatar. It represents a unique crossover between the art community and VTuber culture, solidifying Shigure Ui as a major icon in modern internet subcultures.
