Emu Otori is a member of Wonderlands x Showtime, the musical troupe in the rhythm game Hatsune Miku: Colorful Stage, known as Project SEKAI. Her exaggerated, cheerful persona made her a fan favourite, and 'kuru kuru', a Japanese sound word for spinning, fits her habit of twirling with excitement. Clips of her voice lines spread through Project SEKAI fan edits on TikTok and YouTube, where short energetic phrases are prized for memes. The chant endures because it is instantly recognisable to fans and works as a universal cue for dizziness, spinning or joyful chaos.
