Found the link to the Tsumane video. Also, according to the Vocaloid Wiki, Haku's name translates to "saying negative thoughts", but since saying something negative and complaining are relatively similar, I guess the translation could go either way. (Just going to wait for another user's green light to the trivia before adding it, as is the protocol.)
