Operation Yum Event Guide for Zenless Zone Zero

This event will take place from June 28, 2025 until July 14, 2025.

In order to participate in Operation Yum event you need to reach Inter-Knot Level 15 and complete Agent Story Mole in the Hole I.

To start the event, head to Reverb Arena and find Crispyboo.

Operation Yum is a food related event. It is also part of a real life collaboration event with LiHO TEA in Singapore. If you purchase one of the bundles, you can obtain in-game items such as an avatar.

During the in-game Event, you have to help Crispyboo deliver meals and collect customer feedback to get rewards. Customer commissions unlock with time.

Once you started the event, you will have access to your first commissions. The event is rather short, and there is not much you have to do. Select your commission, teleport to the character to deliver the food, and follow the quest.

Once you deliver the three customers of the day (they are typically in the same area and marker on your map), you get automatically teleported back to Crispyboo. It will then validate your daily deliveries and give you your rewards!

There is nothing more to do for this event!

• 300 Polychrome
• 150 000 Denny
• 1 Boopon
• 15 Senior Investigator Log
