Miku Dayo is a fictional character derived from the popular Vocaloid character Hatsune Miku. Unlike the original Miku, Miku Dayo is known for her exaggerated, mascot-like appearance with a larger head and shorter body. She originated as a promotional character for the 'Hatsune Miku and Future Stars: Project Mirai' game on the Nintendo 3DS. Miku Dayo is often depicted in a humorous light and has become a beloved icon within the Vocaloid community. Her role is primarily as a mascot, bringing a playful and whimsical presence to events and media featuring the Vocaloid franchise.
