What is Agent Trust?
Agent Trust is Zenless Zone Zero’s core friendship system that referring to the protagonist’s relationship with other Agents. Unlike combat-focused mechanics, Trust grows through non-combat interactions, and each level from 1 to 4 unlocks unique perks. It’s not just for lore—higher trust grants practical benefits: extra Inter-Knot Credits, exclusive mission access, and even character-specific customization items that enhance your gameplay experience. Every Agent has their own Trust progression path, so tailoring your interactions to their preferences speeds up growth.
How to Unlock the Trust System
To unlock Zenless Zone Zero’s Trust system, you need to meet core in-game conditions. Once fulfilled, you’ll go through a tutorial to master the basic mechanics:
- Recruit at least one Agent;
- Reach Level 31 – the game’s core account level, upgraded via main quests, commissions, and daily task;
- Start and complete the Anby’s Problem commission in Chapter 2
Anby Demara will be your tutorial Agent for the Trust system. Through her quest, you’ll learn how to use the in-game Knock Knock messenger to invite Agents for interactions . After finishing this tutorial, the Trust system will be fully activated—you’ll then start encountering more Agents across New Eridu’s streets, all available for Trust-building interactions.
How to Check Agent Trust Level
The Partner Profile is an in-game archive that contains information about all known Faction members and playable Agents. You can access it through three official in-game paths: the specific Agent’s chat in the Knock-Knock messenger, the global Character List, or the work corner on the first floor of the Video Rental Store .
This profile offers comprehensive details to track your Trust progression:
- Basic Agent information (gender, height, and date of birth)
- Biographical snippets of the Agents, as well as unique traits they share with their peers
- Your current Trust stage with each Agent, illustrated by intuitive emojis
It serves as a one-stop hub to stay updated on your bond with each Agent and plan your Trust-building strategy effectively.

How to Level up Agent Trust
Agent Invitations
Agent invitations are the core and most efficient way to build Trust. Per official rules, you receive 3 total invitations daily, with each Agent eligible for one invite per day. To streamline access to priority Agents, click the asterisk icon next to the “Invitation” button to pin their chat to the top of your contact list. Sending an invite prompts the Agent to agree to a small interaction; completing this interaction grants Trust Points and raises their Affinity Marker .
Note:
Missing a scheduled meeting with an Agent will result in them contacting you afterward, but no Trust penalties apply.
Prioritize inviting Agents below max Trust Rank. Once an Agent hits the threshold for Friendly, Close, or Trusted Rank, pause invitations—rely on random encounters to break through these thresholds and continue leveling up their Trust.
Random Encounters
Random encounters are essential for breaking through Trust Rank thresholds. Agents wander open districts like Sixth Street, Lumina Square, and Back Alley; their portrait appears below the district name in the Fast Travel menu and on the world map when present. Approach the Agent to trigger a dialogue bubble, then select responses aligned with their personality to earn either a Regular or Significant Trust Increase. There is no daily limit on total random encounters, but you can only gain Trust from the same Agent once per day, and encounters occur at any time without time restrictions.
Quality Time
Quality Time is an exclusive high-reward feature unlocked when an Agent reaches Trust Rank “Close”, accessible via Knock Knock invitations. Each Agent has 5 unique Wish Events ; completing a Wish Event unlocks Free Roam mode with the Agent. In Free Roam, visit marked locations to trigger Fun Events—completing enough Fun Events unlocks exclusive lore dialogues. There is no daily limit on Quality Time sessions, provided the Agent is available.
Conclusion
Mastering Agent Trust in Zenless Zone Zero transforms casual interactions into meaningful rewards and deeper engagement. By leveraging invitations, random encounters, and quality time effectively, you’ll unlock every perk and build lasting bonds with your favorite agents. With LootBar’s Zenless Zone Zero top- up for seamless resource acquisition, you can focus on enjoying the journey of trust progression and maximizing your success.
