Mine was about 51 hours, 48 minutes, and a few seconds. (I spent a good 8 hours grinding on gran pulse for chapter 11, and chapter 13.)

Loaf, I have my doubts that you can beat it in under 40 hours. Ill need picture proof once you beat Orphan.

Edit: Yuki, chapter 5 with 26 hours? Thats terrible. I think I was on chapter 9 with that time.
