It must be evening, not midnight
Zenless Zone Zero Waterfall Soup at Night – Suspicious shadow lurks about
To get the "Timely Assistance Medal IV", Officer Mewmew tells you to investigate a "suspicious shadow" of Waterfall Soup at night in Zenless Zone Zero. However, there are two night options to choose from, and the target only appears under one of them.
Below we explain where to find this suspicious shadow in Zenless Zone Zero.
The time must be set in the evening (the symbol with the moon, not the moon and the cloud) to find our target. You can change the time by resting on the sofa or by clicking/pressing the time in the top left and selecting "rest". If you have already rested that day, you can spend some time in Hollow Deep Dive System or Combat Simulations to pass more time. Completing side quests will also make time pass.
