How to find the suspicious shadow lurking about at Waterfall Soup in Zenless Zone Zero

Zenless Zone Zero is shaping up to be an ambitious gacha title from HoYoverse, and while it lacks an open-world element, Proxies have a lot to do in every area. Some of the major hubs are packed with side quests that can mostly be obtained with the help of Officer Mewmew. You can obtain various tasks from the NPC, like investigating the suspicious shadow lurking about at Waterfall Soup.

Apparently, the owner of the noodle shop has to keep the doors closed at night until the suspicious shadow is found. Hence, try completing the task after unlocking Officer Mewmew on Sixth Street, since this will also fetch you the Timely Assistance Medal IV. Here’s a guide to help you investigate the suspicious shadow rumor in ZZZ.

According to the official description of the Timely Assistance Medal IV, the rumored suspicious shadow appears at night. This basically implies any time after sunset, so you should start your investigation around the evening on the Zenless Zone Zero time system.

Head to Sixth Street, where the Waterfall Soup is located, which is basically the Noodle Shop opposite the Godfinger Arcade. To complete the task, check the alley by the store. You are actually looking for the Treasure Hunt Bangboo beside the motorcycle.

Yes, this Bangboo is the suspicious shadow lurking about at the Waterfall Soup in ZZZ. You might not suspect the creature at first; after all, there’s no official information describing the subject of the rumor.

Moreover, Treasure Hunt Bangboo appears during the evening, so change the time accordingly. To do so, complete commissions and take a nap or spend your Battery Charges at the HIA combat simulations.
