While at Kamurocho in Lost Judgment, you’ll pick up the keyword “stalker”. Open the Buzz Researcher and search by that keyword to learn more about where the stalker was spotted. Make your way to the objective on the southern part of Senryo Ave. in Kamurocho to spot a guy on the roof of the building. Press L3 to examine him. You’ll then take on The Invisible Burglar side case! Speak with Kiba and exhaust all the dialog options. Speak with Kiba again when you’re ready to investigate the building. Once inside the office, press L3 and examine the following:
- Katana
- Safe
- Refrigerator
- Container on floor to the left of fridge
- Chip bag on floor in center of room
- Handprint on ceiling where loud noise came from
When prompted, switch over to the Noise Amplifier and examine the ceiling hatch once again to hear a stomach growling. When asked select the following:
- They’re still up in the attic.
- Roach Exterminator
After the cutscene, the case will close and you’ll receive the Extract Recipe: Provocateur!
