In the neon-lit streets of New Eridu, rumors travel faster than a Hollow opens. For months, players had been whispering about a mysterious new figure in the Public Security files. That speculation finally ended when Zenless Zone Zero version 2.7 went live on April 15, 2026. Cissia stepped into the spotlight as the first snake thiren to join the playable roster, and her arrival immediately felt like a deliberate shift for Hoyoverse's city-based RPG.
Her appearance alone is enough to stop a Proxy mid-stride. Cissia wears black and pink clothing, and a long white tail curls behind her as she moves. A small white snake wraps around her chest, reinforcing the serpent theme without making her look fragile. In battle, she carries a spear, but animation previews show the weapon snapping and bending like a whip sword, which gives her a fluid and unpredictable attack style.
Hoyoverse has confirmed that Cissia is an S-rank agent. She deals electric damage and fills the attack specialty. That makes her the fifth electric attack agent to debut, following Anton, Harumasa, Seed, and Soldier 0. Her signature S-rank w-engine also appeared on the weapon banner alongside her, so players who wanted to pull for both character and weapon had a clear path from day one.
Cissia belongs to the Metropolitan Order Division of New Eridu Public Security, often shortened to N.E.P.S. She is the first playable member from this faction. Because of that, her introduction may open the door to a whole new branch of New Eridu's law enforcement. Before her drip marketing, she was barely visible in the game. The only real clue was a brief mention in one of Sunna's trust events. That tiny reference created plenty of theories, but it did not reveal much about her personality or her role in the larger story.

Voice Actors
Cissia speaks with different voices depending on the language. The four confirmed voice actors are:
| Language | Voice Actor |
|---|---|
| English | Erin Yvette |
| Chinese | Jiang Wen |
| Japanese | Fairouz Ai |
| Korean | Kim I-an |
Her Japanese and Korean voice actors are especially notable because they also voice Xilonen in Genshin Impact. Fans of Natlan's skilled Name Engraver may recognize Fairouz Ai and Kim I-an immediately. From what has been shown of Cissia so far, however, she does not seem to share Xilonen's relaxed artisan temperament. Cissia appears more coiled, watchful, and ready to strike.
Should You Pull for Cissia?
For players planning to add Cissia to their roster, preparation is key. Since she is an S-rank electric attack agent, she could fill a strong damage-dealing slot, especially for accounts that lack electric coverage. Players should check the latest Zenless Zone Zero codes to collect extra polychromes and start saving early. Pity planning matters with S-rank banners, so it is wise to decide whether to pull for Cissia alone or also chase her signature w-engine.
Early impressions point to a character with a lot of visual flair. Whether she becomes a permanent pick in the Zenless Zone Zero tier list depends on her in-game numbers, team synergy, and how smoothly her whip-like spear mechanics perform in real combat. As the first snake thiren and the first face of N.E.P.S., Cissia carries more than a weapon. She carries the weight of opening a new path for future characters.
