Age, height and birthday of each playable agent in Zenless Zone Zero

As a HoYoverse game, you can expect a wide variety of unique characters in Zenless Zone Zero. These characters, called agents, have a variety of backgrounds, and thankfully you'll be able to get them all (if, of course, the summoning goes in your favor).

In this list, you can check out the age, birthday, and height of each playable character found in Zenless Zone Zero. This will also include some information about each character, but don't worry; we will not spoil any story content. This will just be a quick overview of each character and what faction they belong to.

Updated March 15, 2026 by Sanyam Jain: We've added all the new characters released as playable characters since the last update in Zenless Zone Zero, while upgrading the older entries where needed.

Alexandrina Sebastiane

First of all, 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 acts 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 let her prepare snacks and tea instead.

Zenless Zone Zero: Bangboo Tier List

Not all of these little helpers are helpful.

Alice Thymefield

Alice is a member of the Spook Shack along with Yuzuha and Manato, and she is in her first years of life. This is evident with her personality in the main quest where she is still discovering herself, and is also shown to be quite introverted until she warms to you.

Thankfully, she has Yuzuha by her side who fully supports her every step of the way. Alice is also obsessed with symmetryas you can see both in her dialogues and her animations.

Anby Demara

Anby is one of the first characters you meet 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, however, most of Anby's background is unknown.

Although Anby is only a four-star character, her combination of electric and awesome powers is amazing. Both of these effects will cause an enemy to slow down or stop completely, allowing you to get in some extra damage.

Anton Ivanov

Next we have Anton Ivanov. This agent is a member of Belobog Heavy Industries and, like Anby above, also has the Electric attribute. If you were looking for a hard working character, look no further than Anton.

Within the Belobog Heavy Industries faction, you can find Anton working hard and maintaining constant enthusiasm, and according to the official HoYoverse introduction of Anton, he is “full of energy and always rises to the occasion”.

Asaba Harumasa

Harumasa is a member of Section 6 and a master at relaxing. His least favorite is overtime, but he's surprisingly reliable when it comes to it. Harumasa suffers from a rare disease called Ether Aptitude Regression Syndrome, which gives him exceptional Ether Aptitude at the cost of Ether rapidly degrading his body.

The longest-lived person with this disease lived to be 26 years old, so Harumasa can't be older than that. But we know that Harumasa and Seth joined the academy around the same age and got jobs shortly after that, so they should be around their 20s.

Astra Yao

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 off to explore the city incognito.

Although Astra's exact age is unknown, she must be quite young to fit the sweet and bubbly idol persona, but still old enough to remember Joran de Winter in his glory days.

Bone Bigger

Ben Bigger is another member of the Belobog Heavy Industries faction and is the first character on our list who doesn't look like a typical human. However, there is more than meets the eye with Ben; in his own words, he is “sort of a math geek”.

Despite his gruff appearance, Ben is incredibly organized and good with numbers. However, this did not go unnoticed as he was promoted to CFO of Belobog Heavy Industries.

Billy the Kid

Billy is another character that you will unlock 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.

Instead of being an organic human, Billy is actually an AI construct that gained self-awareness. Who knew this self-awareness would manifest itself in the form of being a devoted Starlight Knights fan?

Burnice White

Burnice is the Sons of Calydon's resident pyromaniac, wielding twin flamethrowers with ruthless abandon. She's a bit of an airhead who solves 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 skilled 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 drinking.

Caesar King

Caesar King is the leader of the Sons of Calydon. She is bold and uncomplicated, always charging straight at whatever problems the Sons of Calydon are facing. Although she can be ruthless, Caesar knows when to tone it down and get the job done.

In battle, Caesar is a powerful defensive agent who can protect his allies against heavy hits. She is reliable where it counts, and the ideal leader of the rag tag Sons of Calydon.
