Kagamine Rin & Len

Kagamine Rin/Len (鏡音リン・レン Kagamine Rin and Len ) mostly Kagamine Twins are VOCALOID twins owned and created by Crypton Future Media.

Appearances
Rin has green eyes and short, blonde hair with 5 thin hair clips. She wears white headphones with a large ribbon attached to them. She wears a yellow and gray sailor-style scarf and a white sleeveless button down shirt. She has a tattoo on her arm with the numbers 02 She wears white shorts with buttons that have a thin gold line around the bottom. She also wears black knee-high socks with gold and white lines at the tops on top of white and gold sneakers.

Like his sister, he has blonde hair, he wears white headphone, sailor black scarf, yellow tie, black arm protector and he has a black short with a yellow striped white shoes.

The two of them are also based on a YAMAHA synthesizer. Even their theme color comes from a synthesizer. That's why the details on their leg covers aren't the same for both legs. The synthesizer's they're based on have speakers on only one side. Rin's details are on her left leg and Len's are on his right. I lined them up in designs to that Rin would show her left leg and Len, his right.

Etymology
They have performed at live concerts onstage as animated hologram projections. Their names are derived from the concept of 'left' and 'right', like in stereophonic sound. Their surnames came from the Japanese words for "mirror" (鏡, kagami) and "sound" (音, ne) and they are each other's mirror image.
