Disgaea 4 is just one of two Vita games in the works at RPG specialist Nippon Ichi, along a new title starring fan-favourite Asagi.
The most interesting announce from a western perspective is probably Disgaea 4: Return, a new version of the 2011 PlayStation 3 RPG headed to Vita in Japan in January 2014. An international release has not been confirmed.
However, Nippon Ichi also announced Criminal Girls: Invitation – a working title – which hits Vita in northern winter. Again, no international release was touted.
Much more tentatively, the developer revealed its Asagi 10th Anniversary Commemoration Project. Asagi is a minor Disgaea character who has become something of a mascot for Nippon Ichi; the new game will feature her in a starring role at last. Unfortunately, no platform or release window information was provided.
