In the summer of 2024, Zenless Zone Zero opened a new chapter for Proxies with the Exclusive Channel Unswerving Bullet. The event put the spotlight on Zhu Yuan, a limited S-Rank Agent who fights with Ether and fills the Attack role. From July 24, 2024, at 12:00:00 server time to August 13, 2024, at 14:59:59 server time, her Reception Rate received a significant boost. The channel also raised rates for two A-Rank Agents: Nicole, a Support who manipulates Ether, and Ben, a Defense specialist who brings Fire to the field.

Here's the kicker: the banner did not just walk into New Eridu. It strutted. The Unswerving Bullet was an Exclusive Channel, meaning its limited S-Rank Agent would not become available in the Star-Studded Cast Stable Channel. That detail mattered to Proxies who cared about collection completeness and long-term account value.

Independence The count was independent of and unaffected by other types of Channels
Stable Channel The limited S-Rank Agent would not appear in the Star-Studded Cast Stable Channel

For many Proxies, pulling for Zhu Yuan was a no-brainer. She brought Ether damage, stylish gunplay, and a personality that fit right into the chaotic streets of New Eridu. Nicole and Ben sweetened the deal. Nicole offered Ether Support, while Ben provided Fire Defense. Together, the three Agents gave players a ready-made core for early and mid-game teams. The boosted rates also meant that even players who did not land Zhu Yuan immediately could still walk away with useful A-Rank copies.

The pity mechanics were another reason the channel felt friendly. Because the guaranteed Signal count was cumulative across all Exclusive Channels, every pull on Unswerving Bullet contributed to future limited banners. That system respected player investment. It also encouraged Proxies to keep pulling even if their luck was colder than a winter night in the Outer Ring.

Alongside the Signal Search, HoYoverse ran The Final Callback - Audition Stage. The event asked Proxies to reach Inter-Knot Lv. 8 and unlock the Event feature in the Main Story Prologue - Intermission. It ran for the same window as the banner: 2024/7/24 12:00:00 to 2024/8/13 14:59:59 server time. In the audition stages, players could try out Zhu Yuan, Nicole, and Ben before spending their pulls. Upon clearing the stage for the first time, Proxies could claim rewards on the results screen. It was a smart way to let players feel the team's rhythm, from Nicole's Ether shred to Ben's shield and Zhu Yuan's explosive rounds.

Why did Zhu Yuan matter so much? Several reasons stood out:

  • 🎯 Role clarity: She was an Attack Agent with the Ether attribute, a combination that gave her a clear niche.

  • 💥 Burst potential: Her kit rewarded well-timed combos and energetic play.

  • 🤝 Team synergy: Nicole and Ben on the same banner made it easy to build a functional squad.

  • 🧲 Collection value: As a limited S-Rank, she was not available in the standard pool.

  • 📈 Account growth: New Proxies could use the banner to jump-start their roster.

As of 2026, the original Unswerving Bullet event has long since closed. Zenless Zone Zero has grown, new Agents have arrived, and the meta has shifted more than once. Proxies who missed Zhu Yuan's debut must wait for a rerun or another official opportunity. The audition stage is also closed. For current availability, players should check the in-game Signal Search page and official announcements. The game's schedule moves fast, and HoYoverse does not keep every limited banner around forever.

That said, the Unswerving Bullet remains a memorable chapter in Zenless Zone Zero history. It introduced a fan-favorite character, paired her with two beloved A-Ranks, and gave Proxies a clear goal during the game's early months. For those who were there, the event was a mix of excitement, strategy, and a little luck. For those who were not, it is a piece of ZZZ lore worth revisiting. The channel may be gone, but Zhu Yuan's bullets—and her fanbase—are still unswerving.
