Akita Neru (亞北ネル) is an officially recognized derivative, a fanmade VOCALOID character that is based on an already existing character.
Neru is actually a spoof character made to joke about the "puppets" that was given for the contributor which was branded as "puppets of the agency" by the netizens. This was started when Hatsune Miku movement was on the rise beyond expectations, a Japanese TV station suddenly broadcasted a program that stereotyped Miku users as "anime freaks without stable work experience". And several days later Miku's pictures became unsearchable on main search engines and Miku's article was deleted from the Japanese Wikipedia. Read more about this information here.
Neru officially has no defined voice, however this has not prevented users from attempting to give her one. In some cases Neru has the voice of a boyish-sounding girl, while some people have assigned her to Miku's default voice, but in a higher octave.
