If you start a New Game + and get the true ending again, you get access to a new dungeon with the hardest boss of the game. Did someone find a way to beat it ? I managed to pass the 1st phase but i'm still having trouble with the 2nd phase where i can stall without too much problem, but it's really hard to deal a decent amount of damages. The boss also deal more damages as the turns pass so it's kind of timed. Any tips here on dealing damages ? Edit : I finally beat it with a bit of work, pattern analysis, and finding the best way to deal damages while still surviving.
