Anonymous about 1 yearFYI to everybody, when you beat the boss, check your quest inventory for the Mysterious Xenochromatic Crystal. I don't remember if the game shows you obtained it on your screen right after beating the boss on the 1st try, but when I beat it the 2nd time, it didn't show. However, when I checked my inventory, it was already in there, so don't assume like me that the boss didn't drop it after killing it.
