Yowane Haku is a fanmade character derived from Hatsune Miku, though her design is mainly based on KEI's style for Crypton Vocaloids. Her creator is CAFFEIN, a Japanese artist.
She was created after a humorous posting by someone who bought Vocaloid Miku because her avatar was cute, but when it came to producing a sound with the voicebank, they could not figure out how to do it without Miku sounding mechanical and awful. CAFFEIN created Haku to represent the failures of DTMers who couldn't use synthesizer programs properly, or when they tired they always failed to create anything decent.
While Yowane Haku is meant to be looked at as a DTMer, her existence by the fandom is representing Failed Vocaloids dubbed Voyakiloid.
