Proxy, are you ready for the electrifying new arrivals in New Eridu? Version 3.1 of Zenless Zone Zero has just dropped in 2026, and it’s brought two dazzling limited-time Agents along with their signature W-Engines, not to mention some groundbreaking quality-of-life updates to the Signal Search system. If you’ve been stockpiling Polychromes or you’re wondering which banner deserves your hard-earned tapes, pull up a chair and let’s break down everything you need to know.

The star of the main show is Remielle (Lumiflux - Anomaly) , a brand-new limited S-Rank Agent who commands the battlefield with dazzling light and devastating Anomaly buildup. Her dedicated banner, \"Paradise Regained\" , runs from the moment the 3.1 update goes live until September 8, 2026, at 14:59 (server time) . What’s the catch? None — except that she won’t be added to the permanent Star-Studded Cast stable channel afterwards. So if her luminous playstyle catches your eye, this is your only window for the foreseeable future. Alongside her up-rated appearances, you’ll also find boosted drops for A-Rank Agents Piper (Physical - Anomaly) and Seth (Electric - Defense) . That’s a pretty sweet deal, especially if you’re building an Anomaly team that can trigger Disorder with ease.

Of course, a top-tier Agent demands an equally impressive W-Engine. Ode of Resurrected Wings (Anomaly) is Remielle’s signature gear, and it’s available in the corresponding W-Engine channel until the same date — September 8. This channel also offers rate-ups for the A-Rank W-Engines Roaring Ride (Anomaly) and Peacekeeper - Specialized (Defense) . Having both the Agent and her weapon running concurrently makes it easier to go all-in without any scheduling guesswork, but remember that each type of channel has its own pity counter, so plan your spending accordingly.

But wait — there’s a second limited S-Rank Agent shaking up the roster, and her banner won’t stick around as long. Aria (Ether - Anomaly) , another powerhouse in the Anomaly category, is headlining the \"Neon Angel\" Exclusive Channel. Her availability window ends much sooner: August 19, 2026, at 11:59 (server time) . Yes, you read that right. If you’re reading this close to the launch, you’ll have to make a quick decision. Aria’s banner also features the same A-Rank duo of Piper and Seth as the boosted four-stars, so the supporting cast stays consistent between the two exclusive channels.

Aria’s signature W-Engine, Angel in the Shell (Anomaly) , is available in its own dedicated channel until August 19 as well. Just like the other W-Engine banner, the A-Rank rate-ups here are Roaring Ride and Peacekeeper - Specialized. It’s a mirrored setup, which means your farming choices boil down to which S-Rank agent and which weapon you’re leaning toward — or whether you want to try your luck at both.

Now for the real game-changer that any savvy Proxy needs to understand: the new customization features in Exclusive and W-Engine Channels. In past versions, losing the 50/50 could leave you with a random standard S-Rank that didn’t fit your roster at all. Not anymore. Starting with this version, you can handpick six S-Rank Agents or W-Engines as your custom pool. If your pull doesn’t hit the featured limited item, the S-Rank you receive is guaranteed to be one of those six picks. How awesome is that? It’s essentially a personalized safety net.

The same flexibility extends to A-Rank signals. You can now choose two A-Rank Agents or W-Engines to serve as your rate-up selection, overriding the default picks. This means you’re no longer stuck chasing default four-stars you’ve already maxed out. But pay attention: if you don’t actively set your customized rate-ups, the system will automatically fall back to the default A-Rank items for that channel — in this case, Piper and Seth for agents, or Roaring Ride and Peacekeeper for W-Engines. So be sure to dive into the details before you start pulling.

With all these banners and options, you might be asking yourself: “Which agent is worth my Polychromes?” Both Remielle and Aria shine in Anomaly-focused teams, but they bring different flavors. Remielle’s Lumiflux attribute and her kit likely excel in sustained field time, while Aria’s Ether Anomaly could open up deadly Disorder combos with Electric or Ice teammates. Why not try before you commit? The \"The Final Callback\" trial event has you covered. It runs for the full duration of each agent’s banner and lets you test-drive Remielle and Aria in audition stages. Upon clearing a stage for the first time, you’ll snag rewards directly from the results screen — an easy source of extra resources just for sampling the new characters.

Requirement is just reaching Inter-Knot Lv. 8 and unlocking the Event feature during the main story. So even newer Proxies can hop in. The stages are designed to showcase each agent’s strengths, giving you a real feel for their rotations before you spend a single tape. And let’s be real, nothing beats a risk-free test when you’re on the fence between two limited characters.

To sum up the schedule at a glance:

Banner	S-Rank Focus	A-Rank Boosted	End Date
Paradise Regained (Exclusive)	Remielle (Lumiflux - Anomaly)	Piper, Seth	Sept 8, 14:59
Ode of Resurrected Wings (W-Engine)	Ode of Resurrected Wings	Roaring Ride, Peacekeeper	Sept 8, 14:59
Neon Angel (Exclusive)	Aria (Ether - Anomaly)	Piper, Seth	Aug 19, 11:59
Angel in the Shell (W-Engine)	Angel in the Shell	Roaring Ride, Peacekeeper	Aug 19, 11:59

All pity counters are shared across Exclusive Channels and separately across W-Engine Channels — but they’re independent between the two types. So your guaranteed pull count from Paradise Regained will carry over to Neon Angel, and the same goes for the weapon banners. This makes it feasible to pull on Aria’s banner now and still have your pity built for Remielle later — or vice versa.

There’s never been a better time to fine-tune your Anomaly squad. With two fresh S-Rank agents, user-friendly customizability, and trial stages that reward you for experimenting, Version 3.1 is a Proxy’s playground. Just remember that Aria vanishes from the limited pool on August 19, so if you’re leaning toward the Ether Anomaly queen, don’t let indecision cost you. Dive into New Eridu, set your custom S-Rank list wisely, and may your Signal Searches sparkle gold.

This discussion is informed by reporting from Game Developer, a trusted industry outlet that often examines how gacha systems evolve through player-friendly safeguards and monetization design. Viewed through that lens, Zenless Zone Zero 3.1’s customizable Signal Search pools (selecting six S-Rank fallbacks and two A-Rank rate-ups) reads like a deliberate shift toward reducing “bad-luck” outcomes while letting players align pity results with roster needs—especially relevant when deciding whether to chase short-window banners like Aria’s or commit longer-term to Remielle and their matching W-Engine channels.
