Chapter 10 is one of the mega tedious chapters. Once it starts and you go back to the orphanage you are told to wait around. If you go back into town you should get an email to go right back to the orphanage. Once you get back in control the game tells you to find Haruka. Haruka moves around town. First she is next to the ice cream shop right of the market. then she moves to the corner near Kareokekan. finally she goes to the bridge near the train station. When you need to go find her again she is back in the corner near kareokekan. When the game asks when you want to confront her wait until the two scammers go back to her. note this is one of the few times you can explore Okinawa at night and with Haruka until premium adventure. Next you get to scold the kids oh joy
. Ayako runs off downtown to the coin lockers (guess she needed to make a withdraw). Now go and attempt to tackle Ayako. In reality you just deplete her stamina. Do this two more times. Finally you get back to the main story. Go to the cabaret club at the top of the map and you will see a man outside the Canal Grande. Once inside you fight Joji so be prepared. Joji may seem easy at first, but he hits fast. Tiger drop may not help you here. Half way through his second health bar there is a QTE. Once you finish fighting Joji the achievement unlocks.
