Rin Kagamine

Rin Kagamine, codenamed CV02, is Japanese VOCALOIDs developed and distributed by Crypton Future Media, Inc., and were initially released in December 2007 for the VOCALOID2 engine. She (along with her counterpart, Len) is the second set of vocals for Crypton's Character Vocal Series and are both Character Voice VOCALOIDs. During their Append's production, Wataru Sasaki (aka. Wat) described Rin & Len as two bodies with one soul. She has had umerous installments since such as additional voice banks dubbed 'Append', an update to the VOCALOID4 engine, and an English vocal. Rin is designed to be a deep sounding teenage female, and the female counterpart for the Len vocal also supplied within the package. When the Kagamines were being recorded in 2007, their names were not yet decided. Their given names of Rin and Len were said to be based on "right" and "left" according to Asami Shimoda. She later confirmed in an interview after the Append release that the names were based on Ken and Rin from Hokuto no Ken, derived from a discussion about names that were familiar from her childhood. Their surname was derived from the developing code combining Kagami (鏡, mirror) and Ne (音, sound). This refers to an "echo", which is a sound being bounced back to the user from a different direction caused by soundwaves hitting a surface at a direction that reflects it back the way it came. Their codename of "CV02" means "Character Voice 02". Their voices are provided by the Japanese voice actress, stage actress, and singer Asami Shimoda.
