Backflip said:Yes, it's night time in the game. When I go to Kamuro Castle, the HLA guy only tells me to take care of myself.
That's so weird. I fulfilled the same conditions:
1.) all 100 substories completed.
2.) all IF7 battles completed.
3.) all masters training
and I went to see him at full night and he unlocked. I was also in Premium Adventure mode and had completed the main storyline.
I hadn't (and still haven't) completed the coliseum missions. The first time I tried to unlock Amon, I visited the HLA president and it was dusk (pink sky). He didn't unlock. Then I went back to the hideout and rested again and went back to him during full night (black sky). Then it unlocked.
Glitch maybe? Or if you haven't completed the main storyline, try doing that perhaps?
