Before April 1st, Fjord was considered 'Series 2' of the UTAUpss characters. How can that be possible? Many would ask, as Series 1 hasn't been released yet. Here is your explanation: Donka Fjord was created as a 'joke' character, thus changing his title to JOKALOID. Fjord's full information page can be found here.
The JOKALOID page on the offical PSS website can be viewed here. (Only Japanese language is supported, voicebank may be downloaded on this page.)
