These two are the Kagamine twins, Rin and Len Kagamine. The development of the Kagamine twins began when Crypton formulated the concept of making a pair of female and male voicebanks. The first idea was for two voices of a girl and her mirror image of the opposite gender just like twins. They can either be viewed as brother and sister, lovers, or simply mirror images of each other. Len's item is bananas, Rin's item is oranges, and together their item is a road roller(type of construction vehicle). Len is either paired up with Rin or Miku in a romantic way, while Rin can either be with Len or Saito in a romantic way.
