ZZZ 3.1: Remielle, Sigrid, Banners & Costumes

ZZZ 3.1 Brings First Lumen Agent and Summer Cosmetics

HoYoverse has detailed Zenless Zone Zero version 3.1, launching 2026-07-29, and it's a packed update. The headline addition is Remielle, the game's first Lumen element agent, arriving alongside a full slate of swimsuit costumes and anniversary rewards. For a broader look at ongoing coverage, check the latest Zenless Zone Zero news.

But the update isn't just about one character. Sigrid, an Ice Attacker, joins in the second half, and five new outfits hit the store and events. Here's what you need to know before the servers go live.

At a Glance

• Patch: 3.1
• Release date: 2026-07-29 (server time not specified in official materials)
• New agents: Remielle (S-Rank, Lumen, Anomaly), Sigrid (S-Rank, Ice, Attacker)
• New costumes: 5 total (Remielle, Sigrid, Vivian, Lucy, plus Remielle gown)
• Key events: Summer Waves Roll In, Anniversary Perks, Enigma of the Labyrinth: Operation Bagel
• Free giveaway: One S-Rank agent + their W-Engine (choice of five)

Banner Schedule and Phase Breakdown

Version 3.1 splits its banners into two phases. Phase 1 goes live with the update on 2026-07-29, while Phase 2 arrives at the halfway point. The exact date for Phase 2 is not stated in official materials, but it will end when 3.2 begins.

Phase 1 Banners (Launch)

Banner	Featured Agent	Notes
Remielle	Remielle (S-Rank, Lumen, Anomaly)	Runs throughout 3.1
Aria rerun	Aria	Rerun

Phase 2 Banners (Halfway)

Banner	Featured Agent	Notes
Sigrid	Sigrid (S-Rank, Ice, Attacker)	Ends when 3.2 begins
Rerun	Dialyn	Rerun
Rerun	Harumasa	Rerun
Rerun	Yuzuha	Rerun

Remielle's banner staying up for the entire patch gives you more time to pull, while Sigrid's shorter window means you'll need to plan your Polychromes carefully if you want both.

Should You Pull Remielle or Sigrid?

Remielle is the first Lumen element agent and fills an Anomaly role. That makes her a potential cornerstone for teams built around Lumen reactions, though the full extent of her kit isn't detailed in official materials. If you're a collector or want to invest in a new element early, she's a strong candidate.

Sigrid is an Ice Attacker, a more familiar role. Ice teams already have established supports, so she could slot in quickly if you need a dedicated damage dealer. For a deeper look at her optimal setup, see our Sigrid Best Build Guide in Zenless Zone Zero.

For F2P players, the anniversary giveaway (more below) may let you grab a free S-Rank agent, which could offset the need to pull on either banner. If you're undecided, waiting for community testing after launch is a safe bet.

Costumes and Cosmetics

Five swimsuit costumes are coming in 3.1, plus an additional gown for Remielle. Here's the breakdown:

• Remielle – Seashade Pas Seul (swimsuit)
• Sigrid – Majestic Wavechaser (swimsuit)
• Vivian – Iris of the Shore (swimsuit)
• Lucy – Princess on Holiday (swimsuit, earnable via Summer Waves Roll In event)
• Remielle – Moonlight Whispers gown (veiled and unveiled options, shop purchase)

Only Lucy's costume can be earned for free through the Summer Waves Roll In event. The others must be purchased. Remielle's gown can be bought alone or in a bundle with her swimsuit.

Events and Anniversary Rewards

Version 3.1 coincides with the game's second anniversary, and HoYoverse is celebrating with a generous set of login rewards and events.

Anniversary Perks

• 20 Signal Searches
• 1,600 Polychromes

These are typically delivered via login events, so make sure to log in daily during the patch.

Summer Waves Roll In

This event rewards Lucy's Princess on Holiday costume. Details on tasks and duration are not stated in official materials, but expect it to run for a limited time.

Enigma of the Labyrinth: Operation Bagel

A new mode called Enigma of the Labyrinth: Operation Bagel arrives at launch. No further details on gameplay or rewards are available in official materials.

Operation Yum

An Operation Yum event will also begin rolling out worldwide at the end of July 2026. Specific dates and rewards are not stated in official materials.

Free S-Rank Agent and W-Engine Giveaway

One of the biggest draws is a giveaway that lets you choose one S-Rank agent and their corresponding W-Engine. The five options are:

• Anby (Soldier 0 version)
• Hugo
• Jane Doe
• Lucia
• Trigger

This is a significant opportunity for newer players or anyone missing these agents. The exact method of acquisition (login, event, etc.) is not stated in official materials.

Teams and Synergies

With Remielle introducing the Lumen element, team building may shift. As an Anomaly agent, she likely excels in disorder or reaction-focused compositions. However, without official kit details, it's too early to map out optimal teammates. Unconfirmed — subject to change.

Sigrid as an Ice Attacker fits into existing Ice teams. She may pair well with Ice supports like Lycaon or Soukaku, but again, official synergy data is not yet available. For now, if you have a strong Ice roster, she's a natural addition.

The reruns of Dialyn, Harumasa, and Yuzuha in Phase 2 give players a chance to fill gaps in their rosters. Harumasa is a known Electric Attacker, while Yuzuha and Dialyn offer different utility. If you missed them before, this is your window.

Pre-Patch To-Dos

Before 2026-07-29, wrap up any lingering content from 3.0. Spend your current Polychromes wisely, and if you're close to pity on a limited banner, decide whether to finish it or save for 3.1. Also, check your Monochrome Market double bonus status—it resets with 3.1, so if you plan to buy Monochromes, waiting until after the update may be beneficial.

Day-1 Priorities

Once the update hits, log in immediately to claim any anniversary rewards and start the Summer Waves Roll In event to secure Lucy's costume. Check the new Enigma of the Labyrinth: Operation Bagel mode and see if it offers weekly rewards. If you're pulling for Remielle, her banner is available from day one, so you can test her in the trial stage before committing.

Conclusion

Zenless Zone Zero 3.1 is shaping up to be one of the biggest updates yet, with a new element, two new agents, and a wealth of free rewards. The anniversary perks alone make it worth logging in, even if you're not pulling.
