The story of BOSS here is to go to the port of Ezra first, then go in and stand next to a building like a sailor, talk to him and violate the task of finding Alba, and then go to the innermost part of a shipping company on the lower right to find Alba. Just as he was about to talk, BOSS appeared, took Alba (sailor is BOSS) and went to the dark waterway. Where you hit the BOSS, you have to go up the stairs to a place with two dog. Don't go right or left. Go down the stairs and open the door, then drive the chariot to fight BOSS. After hitting a boss, he didn't actually die. He should continue to talk to his body and play it again. If you don't talk, you will be forced to get off the bus after you go directly to save Alba, and it will be much more difficult to play.
