-( Story related, cannot be missed )-
This was the most difficult fight for me on Hard, but I am sure that, other than that, the fight itself wasn't too hard. Break out your strongest weapons and unleash hard shots on him. Eventually, the place will start to fall apart, and he will become even stronger in his vigilance to defeat you. The threat here isn't from Azimuth himself, but there will sometimes be openings in the floor that will drop you out of the battle. If that happens, you have to start the fight all over again, so be aware of your surroundings.
