The Japanese male voice and character of the singing synthesizer application software originally developed by Yamaha Corporation, Kaito is often depicted as Hatsune Miku’s partner. His character has been licensed by a third party known as Crypton Future in Japan.

This is 帝, the same person from Flickr who provided C.C. from Code Geass: Lelouch of the Rebellion. Only, this is 帝 herself, cosplaying as Kaito. Thanks for sharing your photo with us!
