I think we can safely assume that given the sudden lack of Acerola games being published by Kagura in English, considering that usually it takes Kagura at max 6 months to translate an acerola game since release, I'm pretty sure KG will not be translating this one as soon as we think...now it could also be that they are simply waiting for the DLCs to come out, since I believe acerola also mentioned that there is a DLC planned for Lust Prison, so maybe KG is waiting for the DLCs to then start translating? We may see Monica come out soon now that the DLC is out, but hey it's just speculation
