Yukkuri are fan-made mascots born from the Touhou Project fandom around 2008, when crude Shift_JIS-art drawings of Reimu and Marisa as floating heads began circulating on Japanese forums with the catchphrase asking viewers to take it easy. The deadpan computer voice came from AquesTalk speech synthesis, and yukkuri-narrated videos became a defining genre on Nico Nico Douga. The format later spread to YouTube and TikTok, and it sits comfortably beside other anime meme voices as a nostalgic shorthand for early internet otaku humor.
