Nippon Ichi Software
Kamitani stated that "GrimGrimoire" was the only project he ever designed with the intent of creating a sequel, and despite wishes to do so, Nippon Ichi Software did not put in any requests. Based on this, Kamitani has since made sure to write stories that would stand on their own. Vanillaware later returned to their concept plans for "GrimGrimoire" when developing the 2019 science fiction-themed game "".
