Mikudayo- is a mascot costume based on the Nendoroid version of Hatsune Miku, originally created for the promotion of the game Hatsune Miku: Project Mirai. Fans quickly noted the costume's disproportionate head and vacant, soulless eyes, which transformed her from a cute idol into a semi-menacing internet icon. Known for her catchphrase 'Dayo-', she represents a unique mix of intimidation and unintentional comedy. The meme is typically used to depict someone watching silently or an unstoppable, slightly terrifying force approaching, often associated with consumerism or the Vocaloid fandom's obsessive nature.
