hopefully, but with all the issues happening atm it's probably not going to be continued
Well, we all hope for them to keep the story alive, they did started making the VN called Khemia, telling the story of 3 years after the ending of the VN - Adastra, but the VN - Khemia got on Hiatus because burnout, so they now can focus on the VN - Interea, that tells the story of the 9 months the MC had before returning to earth to start his unifying mission etc.
Though I would prefer for them to keep going with Khemia too, but I understand they need more time writing the story, getting thigs done with real life stuff, we all are suffering from all sides, maybe supporting them on Patreon for some spoilers of the story would be good if you can't hold yourself to wait for the story to come. xD
