Zenless Zone Zero Version 3.1 Phase II runs from August 19 to September 8, 2026. It features Sigrid’s limited S-Rank Agent channel, the Knight’s Extolment W-Engine channel, and two returning-character selection systems.
The main Phase II Signal Search period runs from August 19, 2026, at 12:00 server time to September 8, 2026, at 14:59 server time. Proxies can also use Exclusive Rescreening and W-Engine Reverberation to select certain previously released limited S-Rank characters and W-Engines.
Version 3.1 Phase II Signal Search Overview
Version 3.1 Phase II focuses on Sigrid and several selectable returning S-Rank characters and W-Engines. The main Agent channel features Sigrid, while the W-Engine channel highlights Knight's Exaltment.

The limited S-Rank Agents and W-Engines featured in these Phase II channels do not enter the Star-Studded Cast Stable Channel. Limited Signal Search content may return in future periods.
'Till the Ends of the Sky Signal Search
'Till the Ends of the Sky is the main limited Agent channel for Version 3.1 Phase II, featuring Sigrid as its boosted S-Rank Agent. In turn, Sigrid has the Ice attribute and Attack specialty.
The channel also increases the reception rates for two default A-Rank Agents: Soukaku, an Ice - Support Agent, and Lucy, a Fire - Support Agent.
Sigrid, Soukaku, and Lucy
Sigrid is the limited S-Rank focus, while Soukaku and Lucy are the featured A-Rank options. Their roles and attributes make the three Agents easy to tell apart.
| Agent | Rank | Attribute | Specialty | Channel Role |
|---|---|---|---|---|
| Sigrid | S-Rank | Ice | Attack | Limited featured Agent |
| Soukaku | A-Rank | Ice | Support | Featured A-Rank Agent |
| Lucy | A-Rank | Fire | Support | Featured A-Rank Agent |
The limited S-Rank Agent Sigrid will not be added to the Star-Studded Cast Stable Channel. The same restriction applies to the limited S-Rank W-Engine featured during this period.
Sigrid's Exclusive Channel Mechanics
The Exclusive Channel uses a cumulative guaranteed-signal count that carries across Exclusive Channels. This count remains separate from other Signal Search channel types.
The channel also includes an S-Rank Signal Customization feature. Proxies can select six S-Rank Agents as customized choices, and these selected Agents follow the same data and drop-rate rules as the non-featured S-Rank Agents in the Exclusive Channel.
If an S-Rank Signal does not produce the featured S-Rank Agent, the system guarantees that the result will be one of the six selected S-Rank Agents.
A-Rank Rate-Up Customization
Proxies can also customize two A-Rank Agents for the current Exclusive Channel. These selected Agents inherit the relevant data and drop-rate rules from the current A-Rank rate-up system.
If no customization is made, Soukaku and Lucy remain the default boosted A-Rank Agents for this channel.
This gives players another way to adjust the rate-up selections while keeping the standard Signal Search rules in place.
Knight's Extolment W-Engine Channel
Knight’s Extolment is the limited S-Rank W-Engine featured during Version 3.1 Phase II. It belongs to the Attack category and appears in the dedicated W-Engine Signal Search.
The channel also features two default A-Rank W-Engines: Bashful Demon and Kaboom the Cannon, both listed as Support W-Engines.
Featured W-Engines
Knight's Exaltment is the limited S-Rank option, while Bashful Demon and Kaboom the Cannon receive boosted A-Rank rates.
| W-Engine | Rank | Specialty | Channel Status |
|---|---|---|---|
| Knight's Extolment | S-Rank | Attack | Limited featured W-Engine |
| Bashful Demon | A-Rank | Support | Featured A-Rank W-Engine |
| Kaboom the Cannon | A-Rank | Support | Featured A-Rank W-Engine |
The guaranteed signal count for the W-Engine Channel is cumulative across W-Engine Channels. It is tracked independently from Agent, Exclusive Rescreening, and other channel types.
W-Engine Channel Customization
The W-Engine Channel provides customization options similar to the Exclusive Agent Channel. Proxies can select six S-Rank W-Engines for the S-Rank Signal Customization feature.
When the obtained S-Rank W-Engine is not the featured one, the result is guaranteed to come from the six customized S-Rank W-Engines.
Players can also select two A-Rank W-Engines for the current boosted A-Rank selection. If they do not customize these choices, the channel uses its default A-Rank options.
Exclusive Rescreening Channel
Exclusive Rescreening lets Proxies select one of three limited S-Rank Agents for a special guarantee. Available choices include Dialyn, Ukinami Yuzuha, and Asaba Harumasa.
Proxies can change their selected Agent by switching tabs on the Signal Search page. The first S-Rank Agent obtained during the current Exclusive Rescreening period is guaranteed to be the selected limited Agent.
Available Rescreening Agents
The three selectable Agents cover Physical, Electric, Stun, Support, and Attack roles.
DialynPhysicalStunSelectable limited S-RankUkinami YuzuhaPhysicalSupportSelectable limited S-RankAsaba HarumasaElectricAttackSelectable limited S-Rank
| Agent | Attribute | Specialty | Exclusive Rescreening Status |
|---|---|---|---|
| Dialyn | Physical | Stun | Selectable limited S-Rank |
| Ukinami Yuzuha | Physical | Support | Selectable limited S-Rank |
| Asaba Harumasa | Electric | Attack | Selectable limited S-Rank |
The special guarantee applies once during the current Exclusive Rescreening period. Changing the selected Agent does not reset that guarantee.
Exclusive Rescreening 20% Discount
The first 10 Signal Searches during each Exclusive Rescreening period cost only 8 Encrypted Master Tapes. This is a 20% discount from the standard requirement.
You can use the discount only once during the current Rescreening period. Switching between the three selectable Agents does not restore the discount.
After the first discounted 10-Signal Search, subsequent 10-Signal Searches return to the standard Encrypted Master Tape requirement.
The discount also resets when a new Exclusive Rescreening update begins. Any unused discount does not carry forward to the next period.
How the Special Guarantee Works
The Exclusive Rescreening special guarantee and standard guarantee are tracked separately. When a Proxy obtains an S-Rank Agent for the first time during the current Rescreening period, the special guarantee activates first.
After that special guarantee has been triggered, later S-Rank Agent Signals follow the standard guarantee system. The standard guarantee counter then continues accumulating normally.
The special guarantee itself resets when the next Exclusive Rescreening update begins. An unused special guarantee does not carry into the following period.
W-Engine Reverberation
W-Engine Reverberation applies the same special-selection concept to three limited S-Rank W-Engines. Available choices include Yesterday Calls, Metanukimorphosis, and Zanshin Herb Case.
Proxies can change the selected W-Engine through the Signal Search tabs during the active period.
Available W-Engine Choices
Each selectable W-Engine has a different specialty, giving the channel three distinct equipment options.
| W-Engine | Specialty | Reverberation Status |
|---|---|---|
| Yesterday Calls | Stun | Selectable limited S-Rank |
| Metanukimorphosis | Support | Selectable limited S-Rank |
| Zanshin Herb Case | Attack | Selectable limited S-Rank |
The first S-Rank W-Engine obtained during the current W-Engine Reverberation period is guaranteed to be the selected limited W-Engine.
W-Engine Reverberation Discount
The first 10-Signal Search in W-Engine Reverberation costs 8 Encrypted Master Tapes. The 20% discount applies once during the current period and does not reset when you change the selected W-Engine.
After the discounted search, subsequent 10-Signal Searches use the standard Encrypted Master Tape requirement.
Like Exclusive Rescreening, the discount resets with each W-Engine Reverberation update. Unused discounts do not carry into the next period.
The special guarantee also resets with each update and remains separate from the standard W-Engine guarantee counter.
The Final Callback - Audition Stage
The Final Callback gives Proxies a chance to test five Agents during Version 3.1 Phase II. The audition stages include Sigrid, Remielle, Dialyn, Ukinami Yuzuha, and Asaba Harumasa.
The event uses the same August 19 to September 8, 2026 period as the Phase II Signal Search channels.
Audition Stage Requirements
Players must reach Inter-Knot Level 8 and unlock the Event feature during Main Story Prologue - Intermission. Once eligible, they can access the available audition stages.
Clearing an audition stage for the first time allows Proxies to claim rewards directly from the results screen.
| Agent | Attribute | Specialty | Available in Audition Stage |
|---|---|---|---|
| Sigrid | Ice | Attack | Yes |
| Remielle | Lumiflux | Anomaly | Yes |
| Dialyn | Physical | Stun | Yes |
| Ukinami Yuzuha | Physical | Support | Yes |
| Asaba Harumasa | Electric | Attack | Yes |
The announcement does not list the individual reward quantities in the supplied event details. It confirms that first-time stage clears provide rewards through the results screen.
What Players Should Know About Phase II
Version 3.1 Phase II separates its Agent, W-Engine, Rescreening, and Reverberation guarantee systems. Progress in one channel type does not affect another channel’s guarantee counter.
The standard Exclusive Channel counter is shared across Exclusive Channels. The standard W-Engine Channel counter is shared across W-Engine Channels. Exclusive Rescreening and W-Engine Reverberation each have their own special guarantee systems.
Players should therefore check the specific Signal Search channel before assuming that previous pulls apply to another system.
Limited Availability and Future Returns
The featured Phase II Agents and W-Engines are limited-time content and are not added to the Star-Studded Cast Stable Channel. Featured Signals may return in future Signal Search events.
This means the end of the Phase II period does not necessarily mean permanent removal from all future availability. However, the announcement does not provide a specific rerun date.
For fans who also follow official character goods and collectibles, Animon Life can be another reference point for tracking merchandise connected to characters and game releases. Merchandise availability remains separate from Signal Search availability.
