After completing the Detective Rewind quest, you can take the Suspicious Case Involving Two Recording & Three People commission. This mission requires you to play as a detective and find out what happened to North in Zenless Zone Zero.
How to Complete Suspicious Case Involving Two Recording & Three People Quest in ZZZ
You can start the Suspicious Case Involving Two Recording & Three People commission after reaching Chapter 2 Interlude Intermission. Then, you must go to Lumina Square and speak with a Securityboo named North. You may be familiar with this Bangboo since it shows up during the Detective Rewind quest.
Once you accept the request, you can dive into a Hollow via the HDD system. This time, you’ll be accompanied by North as you gather evidence in this area. Just explore the area until you reach a section with several broken walls. Behind one of them, you will discover the body of Suspectboo, who attacked Securityboo.
After you’re done gathering the evidence and exploring the area, you can go to a safe space to begin figuring out what happened. Fairy will bring you to a special zone where you can answer questions and create a timeline of events to solve the crime.
