The Age, Height, And Birthday Of Every Playable Agent In Zenless Zone Zero

As a HoYoverse game, you can expect a wide range of unique characters to be found in Zenless 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 February 17, 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.

27

Alexandrina Sebastiane

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.

26

Anby Demara

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 can get some extra damage in.

25

Anton Ivanov

Next, we have Anton Ivanov. This Agent is a member 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”.

24

Asaba Harumasa

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.

23

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 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.

22

Ben 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. 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.

21

Billy 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.

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?

20

Burnice White

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.

19

Caesar King

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.

18

Corin Wickes

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 and remains a shining star within Victoria Housekeeping.

17

Ellen Joe

Ellen Joe is the third character on our list who is a member of the Victoria Housekeeping Co., and she happens to have a massive shark tale. Unlike Rina, Ellen isn’t quite as enthusiastic or refined, but this could be due to her age.

Overall, she seems to enjoy relaxing and taking naps rather than expending her energy. Fighting takes a lot of energy though, so she boosts her sugar intake by carrying a lollipop around.

16

Grace Howard

Grace Howard is a member of the Belobog Heavy Industries faction, and as such, her looks definitely fit the part. Grace is a technical expert, with an interest in machinery and pretty much anything that deals with gears or wires.

In an introduction blog post from HoYoverse, we learn that in addition to being incredibly talented, Grace is very nice and well-mannered.

15

Hoshimi Miyabi

Hoshimi Miyabi is the leader of Hollow Special Operations Section 6, a faction under H.A.N.D., who fight Ethereals in Hollow Disasters. Miyabi was given the title of Void Hunter at a young age due to her unmatched skill.

When she’s not fighting Ethereals, Miyabi dedicates her life to all kinds of training; sword training, stamina training; even watching movies with the Phaethon twins can be a kind of training, with the right mindset.

14

Jane Doe

Jane Doe is an undercover agent working for the Criminal Investigation Special Response Team alongside Zhu Yuan. As a criminal behavior specialist, Jane Doe knows exactly how lawbreakers function, allowing her to infiltrate their ranks and gather information.

Given her job, Jane Doe keeps personal information mostly to herself, including her real name and age.

13

Lighter

Lighter is the Champion of Sons of Calydon who fights with an engine-powered gauntlet. As the Champion of the Sons of Calydon, its Lighter’s job to duel other Outer Ring gangs when the two inevitably come to a disagreement.

Despite his role as the Sons’ strongest fighter, Lighter is hemophobic, meaning he faints at the sight of blood. Because of this, he’s almost always wearing his sunglasses, giving him a carefree and cool demeanor.

12

Luciana de Montefio

Sure, you could call this Agent Lucy, but how about saying her full name? That would be Luciana Auxesis Theodoro de Montefio. Not much is known about Lucy and even though she looks a bit childlike, it’s mentioned in the game that she drinks alcohol (placing her at over 18).

Based on the dialogue and text surrounding Lucy, she most likely ran away from home at one point. A missing person report was given in a HoYoverse post, stating that the reward would be generous. Combined with Lucy calling herself ‘Lady Lucy’, she may have come from an affluent family.

11

Koleda Belobog

Despite her small stature (sitting at just under five feet tall), Koleda Belobog is the president of Belobog Industries. Don’t get it wrong though, Koleda doesn’t just sit behind a desk and command her company; she prefers to jump right into the action.

The faction itself was led by Koleda’s father, but after he disappeared, she stepped into the role of president, filling in his shoes and bringing back Belobog Industries from collapse. The other members of Belobog, Anton, Ben, and Grace, all worked with Koleda’s father, making them much older than her.

10

Nekomiya Mana

Who doesn’t love a good cat-themed character? Nekomiya Mana is a curious cat who joins the Cunning Hares in the beginning of the game after previously being part of another group (we won’t spoil this for you!).

There is some confusion about Nekomiya’s age, especially since she looks like she could still be in high school. This may be unlikely though, as there are conversations about her mentioning that she graduated college.

9

Nicole Demara

Nicole is often seen in promotional art of Zenless Zone Zero and is one of the three characters that you unlock right at the start of the game. Although she loves making money, she is somehow very bad at it.

For being the founder of the Cunning Hares, she often leaves the faction’s financial situation “in the red”. Still, thanks to her, the Cunning Hares accept all sorts of odd jobs.

8

Piper Wheel

Piper is the driver for the Sons of Calydon, ensuring the crew get where they need to go, and fast. Despite her laidback attitude, when it comes to cars, she won’t be outdone in a race.

Overall, Piper is a simple gal. She likes cars and reading the newspaper. Despite her young appearances, she has an old soul, and acts as the cranky voice of reason for the rambunctious Sons of Calydon.
