Yakuza 3 Remastered

This chapter is short and straightforward as was chapter 1. The girl you are looking for is on the beach. and the two guys are to your left when you get to and cross the big intersection with the cars going through it. Rikiya is not difficult. As long as you keep pressure on him he will just guard. The chairs around are good sources of damage. Once you defeat him the achievement unlocks.
