Also known as: 唄音ウタ, デフォ子, 呗音ウタ, defoko
An UTAUloid. Her nickname is Defoko (meaning "default child") because she is the default voice data bank for the UTAU program. Her voice is not human based, so it sounds robotic and airy.
She wears a purple Beret, and has short plum colored hair that comes close to her shoulders and matches her Necktie.
