In Lost Judgment, you’ll receive the Underground Casino school story after getting your Focus to level 5. We achieved this when we got the Seiryo High Robotics Club school story to 50% completion. Once you unlock the story, you’ll receive a text from Amasawa wanting you to meet her at the Mystery Research Club (MRC). Head on over there to trigger a cutscene. Exhaust all the dialog options then make your way to the objective in Chinatown to find Hayakawa. After the cutscene, head to the objective nearby outside of Sweet Heaven and speak to the 2 men to learn a bit more about the casino. Next, open your phone and search Buzz Researcher using the new keyword of casino. Select the post of eel then follow the objective into the guys restroom. Press R3 then use the Noise Amp to listen in on the guy guarding the door in the restroom.
Follow the objective to Ebisu Pawn on W. Bayside St. and speak with the Ebisu Pawn Broker. Select the password of “Bon au chic” to receive the Casino Membership Card then pay a fee of 50,000 Y. Exit the pawn shop and head back to the restroom in Chinatown to show the guy your membership card.
Once in the casino, examine the person in a black suit sitting at a table in the back corner. Speak with them to enter a cutscene. When given the option, select “Gamble for the truth”. Purchase chips from the staff then speak with the person in question to begin a match of Poker. If you loose, you’ll be given another chance. Before speaking with her again, press R3 to examine her.
Next, head to the MRC to speak with Amasawa. Select “Smell” when prompted. To find camouflage, make your way to Welcome Pharmacy on Isezaki Rd. and purchase the Perfume for 3,800 Y. Travel back to the casino and speak with Hayakawa to begin round 2! You must win in order for Hayakawa to reveal the truth. After the cutscene, the casino school story will complete!
