There has since been numerous installments such as additional voice banks dubbed 'Append'  as well as an upcoming upgrade to the VOCALOID3 engine which is said to include an English vocal release. They are the second set of vocals for Crypton's VOCALOID Character Vocal Series. Their voices are provided by the Japanese female voice actress, Asami Shimoda (下田 麻美 Shimoda Asami). Concept The development of the Kagamines 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. Crypton had the intention to distribute them as twins, but this was not adopted. After seeing many works that depict their relationships differently, Crypton announced in a magazine interview that those would meet their ideal. However, Crypton's final announcement was that they were neither siblings nor lovers. During Append production, Wataru Sasaki (aka. Wat) described them as having one soul between the two of them. During the boxart for the Append, Wat described it as making the pair seem like twins, due to the fetal position they were in. Appearance KEI was given a concept by Crypton that included Rin and Len's approximate ages, as well as the idea of them being 'mirror images' and, like Miku, androids. KEI was not given any further direction, as he had already drawn the art for the first release in the Character Vocal Series, Hatsune Miku. Rin was the first of the Kagamines to be illustrated and Len was made to match her, following Crypton's concept. Their leg features were designed to mimic speakers.The keytar Len is often featured holding in merchandise is a Yamaha KX5, from which the design of both Kagamines take certain elements. When Rin and Len received a new set of vocals during their Act2 release, KEI took the opportunity to fix art flaws in their artwork. Act1 Rin 1 of 2 Kagamine Rin's introduction artwork: Rin has "Act2" on her arm under her "02" tattoo. Rin's top was changed in the introductory image between versions around the armpit area. Frills were added to the bottom of her top in Act2. Her shoulder was not correctly drawn in the original version. All the yellow bands on her outfit were made bigger on Act2. Her fringe was made thicker above the left eye. In Kagamine Rin's artwork, her left knee was thicker and her right leg was too short. Kei corrected this in her Act2 version. Her right leg position changed and so did the position of her left foot. Forearms have been shortened in Act2. The cyber-on-normal clothing design on their detached sleeves was changed from a green bar to a blue one. Kagamine Len's introduction artwork: Kagamine Len has "Act 2" on his headphones. The cyber-on-normal clothing design on the detached sleeves were changed from a green bar to a blue one. His fringe was reshaped, other strands were adjusted as well. Len's face, particularly around the cheekbones, was reshaped. His left knee had a minor tweak. Boxart changes; Kagamine Rin's leg position was changed in their boxart so it was lifted off the ground, the only way the previous position would have worked was if her leg were deformed or broken. Rin's body itself compared to the length of her legs is shorter than in the original boxart, while the legs are longer. Kagamine Rin's knee is rounded instead of sharp. Both had the cyber details changed on their detached sleeves. For their appends, Wat wanted them to have a sense of transparency with their design In clarification to what he meant by this, he stated the "transparency" was in reference to their hearts. Their Append design and the official illustration were made by オサム (osamu). Continuing the tradition of the Item War Internet Meme, many items were proposed for the pair. In the end, Len's item was a banana, because his hair was commented to resemble a bunch of them, while Rin's item was an orange since her bow gave the impression of orange leaves. Before her release, Rin had the road roller assigned to her by accident in a video that received many views suddenly on December 1, 2007. Kagamine Len had yet to be revealed at the time of the road roller meme
