ZZZ 2.6 Sunna & Aria Trust Events Guide: Unlock + Rewards

Understanding the ZZZ 2.6 Trust System: Core Mechanics

Version 2.6 launched February 6, 2026 at 11:00 AM UTC+8, bringing Sunna during Phase 1 (February 6 to March 4, 2026) and Aria in Phase 2. Both feature unique Trust Events unlocking progressive story content and valuable resources.

Trust progression requires completing Trust Missions, daily chats, Quality Time events, and correct dialogue choices. Content gates behind Trust Ranks: Rank 2 (Friendly), Rank 3 (Close), Rank 4 (Trusted). Quality Time requires Friendly status before activation.

Trust Point Accumulation Methods

Four primary methods:

• Trust Invites (Knock Knock): Once daily per agent, baseline progression
• Trust Events: Largest single gains, three full in-game days cooldown
• Quality Time: Requires Friendly rank, moderate gains, location-specific triggers (Sixth Street, Lumina Square, Fantasy Resort, Ballet Twins Road, Port Elpis)
• Dialogue Choices: Liked options increase Trust moderately, aligned options trigger Significant Trust Increase

Prioritize aligned responses during critical moments to maximize efficiency, especially Week 1 when time-gates create bottlenecks.

Trust Rank Timeline

• Friendly (Rank 2): 2-3 days with daily invites + initial Trust Events
• Close (Rank 3): Additional 4-5 days with Quality Time
• Trusted (Rank 4): 10-14 days total depending on dialogue accuracy

Promoter unlocks at Trust Level 2 after completing specific videotape commission.

Three-day cooldown between major Trust Events means Week 1 players complete approximately two full event cycles per character—early optimization crucial for maximizing Polychrome rewards.

Sunna Trust Event Unlock Requirements

Sunna's Trust Events activate only after recruiting her from 2.6 Phase 1 Exclusive Banner. Primary events—Whimsy in the Triple Meter and Encore for an Old Dream—require completing specific Phaethon's Story and Agent Story chapters.

Unlock sequence:

1. Obtain Sunna through banner pulls
2. Progress through mandatory story chapters introducing her background
3. Complete initial Trust Missions establishing baseline familiarity
4. Access Trust Invite through Knock Knock

Story Prerequisites

Phaethon's Story chapters act as hard gates. Verify all prerequisite chapters completed before attempting Trust Events—partial completion creates confusing lock states.

Agent Story chapters provide character-specific context unlocking deeper Trust Event branches. Takes 15-20 minutes each, rewards Inter-Knot Credit and initial Trust Experience. Skipping permanently locks dialogue branches containing hidden Polychrome rewards available only during first-time completion.

Time-Gated Conditions

First Trust Event starts three-day cooldown before next major event. Week 1 players should plan progression schedules around cooldowns to avoid wasting interaction opportunities.

Season 2 Interlude unlocks after reaching specific Trust Rank thresholds, providing narrative context and exclusive rewards not in standard Trust bonuses. Rushing to Friendly without completing interlude may miss time-sensitive dialogue affecting reward multipliers.

Aria Trust Event Unlock Requirements

Aria follows identical mechanics to Sunna but operates on separate progression track. Recruiting from 2.6 Phase 2 Exclusive Banner initiates her sequence requiring own story completions and Trust Mission prerequisites.

Initial conditions: banner recruitment, story completion, baseline Trust Mission engagement. Aria's events trigger at different New Eridu locations with unique dialogue trees rewarding different response patterns—can't replicate Sunna's optimal paths.

Sequential Event Dependencies

Aria's Trust Events unlock in specific order building narrative continuity. First Wish Event rewards 150 Inter-Knot Credit, 10 Polychromes, 10,000 Dennies, 2 Advanced Chips—unlocks subsequent Quality Time opportunities.

Quality Time available after Friendly rank + prerequisite Wish Events. Entering interest areas during Quality Time triggers Fun Events rewarding materials on 1st, 3rd, 5th completions: 7,500 Dennies, 2 Official Investigator Logs, 1 W-Engine Power Supply each.

Optimal Progression Path

Fastest route: front-load Trust Invites first three days while waiting for cooldowns. Daily invites provide consistent baseline during time-gated periods. Complete all Wish Events immediately upon unlock—largest single-instance gains unlocking subsequent chains.

Godfinger interactions reward 5,000 Dennies on 1st and 2nd completions. Don't consume daily invite limits, can complete alongside other activities. Prioritize during downtime between major events.

Quality Time Event Triggers

Quality Time represents most rewarding interaction type but requires specific conditions. System checks after daily server reset, evaluating Trust Rank, location proximity, completed prerequisites. Must physically enter designated areas to activate location-based triggers.

Event probability increases during peak activity windows when NPCs populate areas. Visit multiple interest areas in sequence during single sessions to maximize trigger opportunities.

Daily Reset Mechanics

Server reset occurs at fixed time daily, refreshing Trust Invite availability and Quality Time pools. Complete daily invites immediately after reset to maximize time window for triggers. Delaying until evening reduces effective window, potentially wasting opportunities.

Three-day cooldown for major Trust Events operates independently from daily reset. Completing event Day 1 at 2:00 PM means next available Day 4 at 2:00 PM, not at next daily reset.

Manual Trigger Methods

Some Quality Time events activate automatically through proximity notifications, others require manual initiation through Trust menu. Regularly check Trust interface for available events marked with notification indicators.

Revisiting completed Wish Events possible after initial completion—replay story without consuming daily limits or affecting progression. Replayed events don't grant duplicate rewards.

Week 1 Hidden Rewards Most Proxies Miss

First week contains time-sensitive rewards harder to obtain after initial windows close. First Wish Event completions grant Polychromes alongside standard rewards—bonus doesn't repeat on subsequent events.

Trust Level Rewards:

• Level 2: 20 Polychromes, 5,000 Dennies, 3 Advanced Attribute Chips
• Level 3: 30 Polychromes, 10,000 Dennies
• Level 4: 30 Polychromes, 15,000 Dennies, Dynamic Wallpaper (character-exclusive)

Total: 80 Polychromes per character during early progression—enough for additional pulls when combined across multiple agents.

Time-Limited Polychrome Bonuses

10 Polychromes per first Wish Event seems minor, but completing all for both Sunna and Aria during Week 1 generates 40-60 Polychromes depending on unlock speed. Combined with Trust Level milestones: 160+ Polychromes from Trust activities alone—nearly a full pull.

Reaching Friendly within first three days unlocks Quality Time before first major cooldown expires. Complete Fun Events during waiting period, earning material rewards otherwise locked. 1st completion bonuses provide Official Investigator Logs critical for character development.

Exclusive Bangboo Interaction Rewards

Certain Trust Events feature Bangboo interactions rewarding unique items unavailable through standard gameplay. Occur during specific story moments, require aligned dialogue to trigger. Disliked responses may skip interaction entirely, permanently missing rewards for that cycle.

Dynamic Wallpaper at Level 4 represents most visible exclusive unlock—account customization demonstrating progression achievement. Cannot be obtained through any other method.

Trust Gift Preferences: Sunna & Aria

Gift-giving provides supplementary Trust progression outside events. Each agent features preferred gift categories granting increased Trust points versus neutral/disliked items. Sunna and Aria maintain distinct preference profiles requiring separate acquisition strategies.

High-value gifts cost 1,000-3,000 Dennies from New Eridu merchants or require material exchanges. Trust point return varies: 50 points neutral gifts to 200+ points perfectly aligned preferences. Prioritize aligned gifts during early progression when each point impacts rank-up timelines.

Gift Acquisition Locations

• Sixth Street: General-purpose gifts, food items, common trinkets
• Lumina Square: Premium gifts, higher costs, better alignment rates for specific archetypes
• Fantasy Resort/Ballet Twins Road: Specialized vendors, unique items, perfect gifts for particular agents (availability rotates)

Material-based gifts require farming specific resources. Better Trust point ratios than purchased items but demand time investment potentially exceeding value gained. Week 1: focus purchased gifts to accelerate initial progression.

Gift Timing Strategy

Presenting gifts before Trust Events maximizes psychological impact, though mechanical benefits identical regardless of timing. Daily gift-giving maintains consistent engagement; batching during rank-up pushes minimizes menu navigation. Neither offers mechanical advantages—depends on personal preference.

Gift inventory management critical when managing multiple characters. Bulk purchasing reduces travel time but requires Dennies investment competing with other activities. Balance stockpiling against immediate resource needs.

Dialogue Choice Impact Analysis

Dialogue choices directly affect Trust point gains through liked/disliked/aligned system. Aligned responses trigger Significant Trust Increase notifications providing 2-3x points of standard liked responses. Identifying aligned options requires understanding character personality and narrative context.

Sunna's preferences: Responses demonstrating understanding of her background and respect for professional expertise. Acknowledge skills, show interest in work. Avoid dismissive or overly casual responses.

Aria's preferences: Empathy and emotional intelligence over formal respect. Acknowledge feelings, demonstrate personal investment in wellbeing. Purely logical/detached responses often neutral rather than liked.

Recommended Response Patterns

General guidelines for maximizing aligned responses:

• Read all dialogue options before selecting
• Consider character background from Agent Story chapters
• Choose responses reflecting Proxy's growing relationship
• Reference previous interactions or demonstrate memory of character details

Consistently achieving aligned responses reaches Trusted rank 30-40% faster than random selection. Time investment in understanding dialogue mechanics pays dividends across all current and future character releases.

Trust Point Farming Strategies

Fastest route combines daily Trust Invites, immediate completion of all Trust Events, strategic gift-giving during rank-up pushes, consistent Quality Time participation. Missing daily invites loses 7-10% potential weekly progression, creating compounding delays extending timelines by weeks.

Week 1 optimization schedule:

• Days 1-2: Complete first Wish Events for both Sunna and Aria within 48 hours
• Days 3-5: Reach Friendly rank through daily invites + gift supplementation
• Days 6-7: Target second Trust Event cycle + initial Quality Time engagement

Daily Trust Point Cap

No explicit daily caps, but limited Trust Invites (once per agent daily) and event cooldowns create effective maximums. Accumulate approximately 150-200 Trust points daily per character through combined invites, gifts, event participation. Enables Friendly in 2-3 days, Trusted in 10-14 days with optimal execution.

Efficiency comparison:

• Trust Invites: Best time-to-value ratio, 2-3 minutes daily, guaranteed progression
• Trust Events: Highest single-instance gains, multi-day cooldowns
• Gifts: Flexible supplementary progression, requires Dennies investment
• Quality Time: Moderate gains + material rewards, valuable dual-purpose

F2P players prioritize time-based methods (invites, events) over resource-intensive approaches (gifts) during early progression. Spenders can accelerate through gift supplementation, though time-gates mean even unlimited resources can't compress timelines below 10-12 days for Trusted.

Complete Trust Reward Breakdown

Trust Level milestones follow standardized patterns. Both Sunna and Aria provide identical Polychrome totals (80 across Levels 2-4) and comparable Dennies (30,000 total). Primary differentiation: Dynamic Wallpaper designs at Level 4.

Wish Event rewards (per completion):

• 150 Inter-Knot Credit
• 10 Polychromes
• 10,000 Dennies
• 2 Advanced Chips

With 3-4 Wish Events per character during full progression: 450-600 Inter-Knot Credit, 30-40 Polychromes. Combined with milestones: 110-120 Polychromes per character.

Long-Term Value Assessment

110-120 Polychromes per character represents ~70% of single pull. Across roster of 10 characters, complete Trust progression generates enough for 7-8 additional pulls—significant value for F2P accounts.

Material rewards from Fun Events and Godfinger accelerate character development. Official Investigator Logs reduce farming requirements, Dennies offset W-Engine enhancement and skill leveling costs. Completing all Trust content for both Sunna and Aria during Week 1 gains 2-3 days equivalent farming value in materials.

Advanced Tips from Experienced Proxies

Multi-character Trust management: Complete all Trust Invites in single session immediately after daily reset, then check Quality Time triggers during natural gameplay breaks. Ensures consistent baseline progression while capturing spontaneous opportunities.

Avoiding Week 1 mistakes: Understand time-gate mechanics, prioritize first-completion bonuses. Don't delay Wish Events while focusing combat content—miss Polychrome bonuses funding additional banner pulls.

Preparing for Future Trust Events

Each new character introduces additional Trust tracks competing for daily engagement. Develop scalable routines accommodating expanding rosters without proportionally increased time. Tiered priority systems—intensive effort on new limited characters, baseline engagement with permanent roster—enable sustainable management across 15+ characters.

Resource Optimization Strategies

Limited play time focus:

• Daily Trust Invites: 5-10 minutes total
• Immediate Trust Event completion upon unlock: 15-20 minutes per event
• Opportunistic Quality Time during regular gameplay

Minimal routine ensures consistent progression without dedicated farming sessions competing with combat content.
