It looks like the trademark that Nippon Ichi created a while ago was indeed for a sequel to "Kamisama to Unmei Kakumei Paradox" (
The Guided Fate Paradox). This sequel is called "Kamisama to Unmei Kakusei no Cross Thesis" and is set to release on July 24th in Japan for the PS3.
Details about the game
One interesting thing to note is that the game will use 3D chibi instead of sprites. Apparently, people didn't like the sprites in the first game which is news to me. I really didn't see any problems with them. They weren't high-res like the ones in the recent Disgaea games but I still thought they looked good.
Another thing mentioned in the interview was that this game would be easier to play and understand. I didn't think the main story was too hard in the first game but I didn't really feel like doing all of the post-game stuff. The formula just got tiring after a while so I hope they do a better job at keeping this one fresh. It was still a great game though and my first experience in the "roguelike" genre.
Also, I don't know how I feel about having one of the heroins die if I don't choose them.
