"KAITO (カイト) is a Japanese VOCALOID developed originally by Yamaha Corporation and distributed by Crypton Future Media, Inc.. He was one of the 4 known "Project Daisy" vocals. His VOCALOID3 update was developed and distributed by Crypton. He was initially released in February 2006 for the first VOCALOID engine. There has since been a second installment developed for the VOCALOID3 engine dubbed KAITO V3. His voice is provided by the famous Japanese singer, Naoto Fūga (風雅なおと)."

"The Original voicebank is based on a professional singer. It was a male Japanese vocal that leaned towards genres such as jazz, but due to its high compatibility with the original VOCALOID engine, was easily adaptable to many other genres of music. When KAITO was updated, the voicebank had to be completely re-done with a similar tone to the original, thus some aspects of the vocal have changed in consequential versions. The vocal was also a counter-partner to the MEIKO "Straight" vocal originally."
