Uta Utane, or Defoko is an official UTAU. She is the default voicebank for the UTAU program. Uta Utane literally means "song song sound," "uta" meaning song and "ne" meaning sound. Defoko means "default girl," "defo" meaning "default" and "ko" being a common name ending for girls. Both names can be used interchangeably.
Uta is cool and usually friendly. However, she can be unpredictable at times. She appears lonesome and dreary. Despite the fact that Uta considers Momo Momone her friend, she is usually seen bullying the latter.

She, along with Teto Kasane and Momo Momone, were the first three UTAUs to be released to the public. Because of this, they are often refered to as "The Three UTAU Girls" and frequently appear together.
An English voicebank is in production, giving Uta the ability to sing in both Japanese and English.
