Following what seems to be a transition for the Hyperdimension Neptunia series from the PlayStation 3 to the PlayStation Vita, Compile Heart a few months back announced plans to do a spin-off titled based on Noire, the CPU Goddess for LaStation in the franchise.
Titled Chou Megami Shinkou Noire Gekishin Black Heart (超女神信仰 ノワール 激神ブラックハート), this PlayStation Vita exclusive game is set for release on the PlayStation Vita during May 2014 in Japan. As always, international release dates have yet to be formally confirmed.
The company have released a brief two minute trailer recently which shows off a number of returning characters (Neptune, Noire, Blanc and Vert) in addition to some new characters including Lee Fey, Ain Ar, Restore, Saori, Win and Lady Wakku. This is about half of the currently announced characters, who are all based on video game characters / series.
