Hey there, Proxies! It’s March 2026, and New Eridu is basically flashing neon signs at my Polychrome stash. The latest Signal Search Event is live from 2026/03/04 12:00 to 2026/03/23 14:59 (server time), and I’m not going to lie—my savings are about to take a hit.

If you’ve been holding out for a new Anomaly carry or a Physical Support, this is the moment. Let’s break down what’s actually on offer, how the pity works, and how to grab every last reward.
The Signal Search Lineup
This event isn’t just one banner—it’s four, and they’re all running during the same window. Here’s the full picture:
| Channel Type | Limited S-Rank | A-Rank Rate-Ups |
|---|---|---|
| Agent Banner 1 | Aria (Ether - Anomaly) | Anton (Electric - Attack), Seth (Electric - Defense) |
| W-Engine Banner 1 | Angel in the Shell (Anomaly) | Drill Rig - Red Axis (Attack), Peacekeeper - Specialized (Defense) |
| Agent Banner 2 | Yuzuha (Physical - Support) | Anton (Electric - Attack), Seth (Electric - Defense) |
| W-Engine Banner 2 | Metanukimorphosis (Support) | Drill Rig - Red Axis (Attack), Peacekeeper - Specialized (Defense) |
A quick look at the first Agent banner—Aria is an Ether Anomaly unit, which means she’s all about that beautiful disorder damage. Anton and Seth are the A-Rank companions keeping the pull pool lively.

Then we have the limited Anomaly W-Engine, Angel in the Shell, an Anomaly-type engine that looks like it was built specifically to make Aria’s numbers go brrr.

Not pulling for Aria? Don’t sleep on Yuzuha. She’s a Physical Support who can keep your team upright and swinging. Her banner shares the same A-Rank lineup, which honestly makes building pity on either Agent channel pretty efficient if you still need Anton or Seth.

And yes, there’s a limited Support W-Engine too: Metanukimorphosis. It’s a Support-type engine, so if you’re maining Yuzuha, this is probably the shiny toy you’ll want.

Pity and Channel Rules You Need to Know
Let’s talk pity, because the rules here can save you a lot of headaches. First, the limited S-Rank Agents and W-Engines above will not be added to the Star-Studded Cast Stable Channel. So if you want them, this is your window.
The Agent channels are called “Neon Angel” and “Whispered Tales.” They are Exclusive Channels, and your Search count for guaranteed Signals is cumulative across all Exclusive Channels. In plain English: if you lose the 50/50 on Aria’s banner, that pity carries over to Yuzuha’s banner—but it does not carry over to the W-Engine channel. Keep that in mind before you start mixing pulls.
The W-Engine channels are “Dazzling Choir” and “Dazzling Melody.” Just like the Agent side, the guaranteed Signal count is cumulative across all W-Engine Channels, but it’s independent of every other channel type. So don’t expect your Agent pity to help out your W-Engine pity—they’re in different lanes.
One more thing: if you’re ever confused about the fine print, hit “Details” at the bottom-left of the search page. It’s free, and it beats guessing.
Free Tryouts and Cooperation Exercise Rewards
This is my favorite part, and yes, it’s completely free. During the same event period (2026/03/04 12:00 – 2026/03/23 14:59 server time), you can jump into audition stages and actually test out Aria (Ether - Anomaly), Yuzuha (Physical - Support), Anton (Electric - Attack), and Seth (Electric - Defense) before you spend a single Polychrome.

Here’s what you need to qualify:
-
Reach Inter-Knot Lv. 8
-
Unlock the Event feature in the Main Story Prologue - Intermission
Once you’re in, clear each stage for the first time and the rewards will pop up right on the results screen. If you’ve already completed a Cooperation Exercise stage for one of those A-Rank Agents, you can head straight to the event interface and claim the corresponding test-stage rewards without redoing the fight. That’s a nice little time-saver, and I’ll take all the free Polychrome I can get.
Honestly, I’d run the tryouts even if you’re just curious. It’s a no-pressure way to feel out Aria’s anomaly rhythm or Yuzuha’s support timing before you commit.
Now if you’ll excuse me, I have a date with the Signal Search button. Good luck, Proxies—may your pity come early and your 50/50s be kind.
