This is the most popular and well known Vocaloid out there, and if your a anime fan and haven't heard her name at least once.... you're officially not an anime fan. This is Hatsune Miku. Crypton had the idea to release Miku as "an android diva in the near-future world where songs are lost". Miku's twin-tails are well known and even gained the title for best set of twin tails in the 2000' period. The digital design on Miku's skirt and boots are based off synthesizer program colors. Her character item is a Leek, and she can be paired up in a romantic way with either Kaito Shion or Len Kagamine.
