Zenless Zone Zerofeatures multiple opportunities for players to earn rewards. One of them is theOfficer Mewmew missions. Once playersunlock Lumina Squareafter finishing Main Quest Chapter 2: Interlude, then only will they gain access to Officer Mewmew.
Officer Mewmew will navigate you to the first quest in the medal mission. You can find him opposite the Public Sector Police Station for the rest of the medals. Each medal can only be obtained across various time periods in the day, so verify to keep an eye on the time. Otherwise, you might miss it. Furthermore, the missions are rather random and cannot be obtained in any particular order, so it’s best to always check the district details for any active missions around to avoid missing them and having to wait.

Updated on July 13, 2025, by Aditi Jeyanathan:Zenless Zone Zero players will need to spend quite a bit of time in Lumina Square if they wish to complete all of Officer Mewmew’s missions. On top of that, the Page 2 missions can be just as difficult to complete as those from Page 1, ensuring that players will be kept busy for quite some time while they attempt to please Officer Mewmew. For those struggling, this guide has been updated to feature all Page 2 Lumina Square Mewmew missions, outlining where players must go to start them and what needs to be done in order to complete them.
