“As long as I can be with you, even my digital heart will start to throb. Like a quantum wind, my heart will start to sway.”
― Rin and Len Kagamine

Kagamine Rin (鏡音リン・レン), codenamed CV02, is a Japanese VOCALOID developed and distributed by Crypton Future Media, Inc., and was initially released in December 2007 for the VOCALOID2 engine. She is part of the Character Vocal Series and is a Character Voice VOCALOID. There has since been numerous installments such as additional voice banks dubbed ‘Append’ as well an update to the VOCALOID4 engine and an English vocal. She is the second set of vocals for Crypton’s VOCALOID Character Vocal Series.

Her voice is provided by the Japanese female voice actress, stage actress and singer, Asami Shimoda (下田麻美 Shimoda Asami).

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. Their main design, of which is most noticeable on their boots, uses the YAMAHA EOS as a design base.

Also, each Kagamine has a particular musical clef symbol associated to their design. Rin has a G-clef (Treble-clef) on her shirt, and Len has a F-clef (Bass-clef) on his. In their Append redesigns, they are found on chokers rather than their shirts. Check out the Cosplay-porn parody version.
