As a HoYoverse game, you can expect a wide range of unique characters to be found inZenless Zone Zero. These characters, called Agents, have a wide variety of backgrounds, and thankfully, you will be able to obtain them all (if, of course, summoning goes in your favor).
In this list, you can check out the age, birthday, and height of every playable character found in Zenless Zone Zero. This will also include a tidbit of information about each character, but don’t worry; we won’t spoil any story content. This will just be a quick overview of each character and what faction they belong to.
Updated July 25, 2025 by Jacob Whaling: We’ve updated this list to include the new characters that have been added to the game since last time, as well as updated a few characters who we’ve since learned more about.

First up, we have Alexandrina, or Rina for short. This Agent is a member of the Victoria Housekeeping Co., and as such, looks like a very cute maid. As the head of the faction, Rina is very motherly and refined.
Rina is a five-star character, and functions as a support character with the Electric attribute, making her a perfect addition to any team with some heavy hitters. Of course, you can also have her prepare snacks and tea instead.
Early 20s

Anby is one of the first characters that you mean in the game, along with Nicole and Billy. Together, the three are part of the Cunning Hares, with whom you often work closely. Outside of this though, most of Anby’s backstory is unknown.
Although Anby is just a four-star character,her combination of Electric and Stunning powers is great. Both of these effects will cause an enemy to slow or halt altogether, so you canget some extra damage in.
Early 30s
190 cm / 6'3"
May 2
Next, we have Anton Ivanov. This Agent is amember of the Belobog Heavy Industries, and like Anby above, also has the Electric attribute. If you were looking for a hardworking character, then look no further than Anton.
Within the Belobog Heavy Industries faction, you can find Anton working hard and maintaining constant enthusiasm, and, as per the official HoYoverse introduction of Anton, he’s “full of vigor and always rises to the occasion”.

Harumasa is a member of Section 6, and a master of slacking off. His least favorite thing is overtime, but he is surprisingly trustworthy when it counts. Harumasa suffers from a rare disease called Ether Aptitude Regression Syndrome, giving him exceptional Ether Aptitude at the cost of the Ether quickly deteriorating his body.
The longest-lived person with this disease lived to 26 years old, so Harumasa can’t be older than that. However, we do know that Harumasa and Seth joined the academy around the same age and got jobs shortly after that, so they should be around their early 20s.
Mid 20s
176 cm / 5'9"

Astra Yao is New Eridu’s biggest idol. Inspired by the late Joran de Winter, Astra hopes to follow in his footsteps and bring joy to New Eridu through her music. Her best friend and bodyguard, Evelyn, is almost always by her side, except when Astra sneaks away to explore the city incognito.
While Astra’s exact age is unknown, she must be fairly young to fit the cute and bubbly idol persona, but still old enough to remember Joran de Winter in his glory days.
Mid 30s
192 cm / 6'4"
December 23
Ben Bigger is another member of the Belobog Heavy Industriesfaction, and is the first character on our list who doesn’t look like a typical human. There is more than meets the eye with Ben though; in his own words, he’s “kind of a math nerd”.
Despite his rough appearance, Ben is incredibly organized and great with numbers. This didn’t go unrecognized though, as he was promoted to the Head of Finance within Belobog Heavy Industries.
188 cm / 6'2"
November 25
Billy is another character that you willunlock very quickly in the game. Right from the start of Zenless Zone Zero, Billy was a fan favorite, with many players loving his eagerness and enthusiasm for combat and the Starlight Knights.
Rather than being an organic human being, Billy is actually an AI construct who gained self-awareness. Who knew this self-awareness would manifest in the form of being a dedicated Starlight Knights fan?

Burnice is the Sons of Calydon’s resident pyromaniac, wielding dual-flamethrowers with reckless abandon. She’s a bit of an airhead, solving most problems with fire, which more often than not causes problems for the other Sons of Calydon, but sometimes is just the right solution.
Burnice is also a deft mixologist, mixing up new Nitro Fuel recipes for the Sons. Really, she just loves fuel more than anything, whether it’s for vehicles, flamethrowers, or the drinking kind.
March 16
Caesar King is the leader of the Sons of Calydon. She is bold and straightforward, always charging directly at whatever problems the Sons of Calydon face. While she can be reckless, Caesar knows when to tone it down and get the job done.
In battle, Caesar is a powerful defensive Agent, capable of shielding her allies against big hits. She’s dependable where it counts, and the ideal leader for the ragtag Sons of Calydon.

Corin is a young and shy member of the Victoria Housekeeping Co. While she does carry around a very intimidating weapon, it’s offset by the cute, teddy bear backpack that she is always seen wearing, as well as the little pink charm hanging from the weapon itself.
As a young member of the faction, Corin lacks self-confidence and is often seen stuttering or just being flustered in general. Still, he manages to get her job done andremains a shining star within Victoria Housekeeping.
