#if you have diff hcs or think the canon leans towards a diff interpretation feel free to add on i love listening to that kind of thing :-)

[welcometoteyvat]

i am very curious (and i'm asking this not with any malicious intent) but what ages do you see the genshin characters! i personally see them (most of them) as adults, even collei. even if they were teenagers, time passes in-game (i.e. lantern rite happens every year and we already had 2 lantern rites in-game) so they'll eventually grow to be adults.

tldr: I have schrodinger's age headcanons

long answer: if they're in a ship with a ""clearly"" adult character, I'll assume they're young adults; idk I feel like there's some blurring of age and what growth stage you're in when people are around 17 to 20 (from my experience) so I think it's vague-ish enough that you could probably do what you want.

If they're not in a ship I see some of them as adults and some as still teens/underage. as a general rule of thumb a character's age is solely dependent on what I want at the moment, although I do think the way some characters are written (ie character arcs, character stories and general personality) pushes me to view them as underage (will explain more but the character I'm thinking about most w this is Xingqiu). Some of them read to me as clear adults, and then there are some in-betweens where I just have "vaguely young looking" in my hcs LOL

you bring up a good point that time is passing in game although we don't see it reflected in the character models—everyone points out that Xiao opens up a bit more every lantern rite, but fandom (and genshin devs too ig 💀) definitely forgets that all the other characters are also growing/changing. w/ 4.1 around the corner my personal wish is for hu tao, xingqiu, and chongyun's relationships to each other get developed more so that their relationships (as described through their voicelines abt each other) don't feel so flat,,,,,, it would also help with the sense of "time is passing in game for ALL characters", since we almost never get this kind of evolving relationship portrayed between 4*s/non endgame important charas.

I have too much time on my hands so I'll also just run through all the teen/short models there are for each region and list whether my personal headcanons are adult or minor (at least their ages when we "meet" them in canon):

liyue (mortal/mortal adjacent characters): yanfei, chongyun, xingqiu, hu tao, xiangling, xinyan, yun jin, keqing

yanfei and keqing are solidly adults to me, yanfei's a lawyer and keqing's also in a govt job so both of them feel around like 25-27 to me. Definitely somewhere around their mid-20s, although I can also see them as younger, especially Keqing, because of her overall attitude/perspective on life and the gods. iirc her character stories show how her worldview's grown/broadened to be not as naive/black and white, so I feel like she's still in the process of maturing. If you told me Yanfei was like 23 (appearance wise) I guess I'd believe you too, since she's a very peppy person who seems to be running all over the place all the time, doing errands for madame ping, checking on her clients, taking new cases etc. I feel like it gives her youthful energy, so I can see it if people hc her on the younger side of her 20s (in human years I forgot how her half-adeptal blood works).

I see the other 6 as a friend group (liyue 6ang let's go) so they're either all teens or all adults depending on the portrayal. You can obviously view them as adults all the time, but I don't get those vibes. Xinyan and Yun Jin might be like 18-19, but if that's the case, I can't see the other 4 being any younger than 17, just because I think they're all almost the same age or 1-2 years apart maximum. For some reason so many people view Hu Tao and Yun Jin as adults but at the same time think the others are minors? Idk about that.. genshin has shown that Xiangling, Xinyan, and Yun Jin are pretty close friends, and then always put Xingqiu and Chongyun together for the ship bait, so maybe that's the root of fanon's age hcs. However, I think if some of them are young adults, then all of them are. There's a max 2 year age gap between all 6 of them idk idk I really can't see it otherwise.

To me, Xingqiu's arc reads like a 16 year old finding his footing in the world. Hiding martial arts novels under his bed, tired of playing dutiful 2nd son and sneaking out to live out his idealized wuxia dreams, his multiple voicelines where he's implied to be super worried about us giving away his involvings in the Guhua sect, they all read like he's still trying to figure out his role in his family (what he wants it to be, and what his parents want it to be). He's also very naive about the world, but learning. He just feels a lot like how (chinese) teenagers grow up and like. growing into or out of the paths given to us by our parents. ... or i could just be projecting! Anyways, in my no ships world, he's a 16-17 yr old. Chongyun's clan and family play a not-insignificant role in his backstory, so I think he's the same age as Xingqiu, just older by a month for the flex. Lowkey I don't have as much reason for him as the others, but I think they're in the same age range by association; probably almost 18 at most. Hu Tao's character stories explicitly state she's 13 when her grandfather passed away, and I think she becomes Director not long after this, so I would say she's also around 16-17 when the game starts. @.acatoner who draws quite possibly my favorite interpretations of the gang(TM) once mentioned they see her with spoiled younger sister energy and honestly yeah. she's an only child but has the strongest solidarity with Xingqiu (they're the bratty younger siblings of the friendgroup). Out of all of them, Xiangling is the one with the most plausible job if she was like, young: being a chef apprentice with her dad to continue the family business is pretty reasonable. Middle child energy, probably 17. We did meet her when she was in Mondstadt foraging ingredients, so I'd say she's not very young, but still young enough for her dad to chew her out during moonchase for being like messy or clumsy or smth? Xinyan and Yun Jin.... I think Yun Jin is at least almost 18—running a well acclaimed opera troupe is a pretty big undertaking imo, even if her parents are there to like guide her and whatnot. Same with Xinyan, 17-18 range, although she def started playing rock publicly when she was way younger.

inazuma: shinobu, heizou, kazuha, kirara, gorou, kokomi, ayaka, yoimiya

Disclaimer I have not read the Lore and don't know whether actual ages are given for Ayaka and Ayato (specifically pointing them out because iirc their and Thoma's character stories are the most specific ones wrt the timeline).

I see basically all of them as adults, ayaka might be an exception but she's like 17 minimum in my head. That's pretty interesting considering I labeled almost all the liyue short models as teens. From what I can remember of their character stories, the Inazuman characters seem to be portrayed as having their formative struggles set In the Past (probably a couple years before we meet them) so perhaps that's why I see them as solidly young adults. Additionally, Inazuma's arc and its war pushes me to see all of them as adults, even if they're still obscenely young to be generals and strategicians. The exceptions I can see to this are only Yoimiya (smaller role in archon quest and not related to the government), and Shinobu + Heizou, who were released later. Yoimiya's maturity really stands out to me—from the way her neighbors and old people converse with her, and her overall character arc + second story quest, I cannot see her as below like 19 at least. Shinobu manages an entire unofficial gang and has countless certifications under her belt plus ex-shrine maiden stint—she probably isn't less than 23. It would be cute if she were the same age as Yanfei but just started law school later, so Yanfei's still her senior. I think there's not much to say on Heizou either, he's friends with Kazuha and has a real job, so I can't read him below 20-21. I don't know anything about Kirara (don't have her, haven't read her stories) but I also just get the vibes of like 20-something errand girl SDFDSSKDFJS in a modern au she'd deliver to teyvat/inazuma's college campus for sure

mondstadt (humans): barbara, razor, bennett, fischl, mika, amber, noelle, sucrose

this is a mix again, for Barbara Razor Bennett and Fischl they give me kid vibes, like little adventure gang things. Reddit apparently cites Mona called Fischl an adult in the 2.8 Midsummer Fantasia GAA event, so I mean. I guess she's 18 there—might've been 16 when we met in game the first time (1.2?? scaramouche fake stars event or something?) Idk really. Their group collectively gives me 16 year old vibes, at least when we start the game. I can see it if all of them have aged to 18 now—it just makes sense in my head lol. Mika feels like an 18 year old; mostly because of his relationship with Huffman. Amber seems vaguely adult-ish, I'd say 19 or so, maybe 20 during shadows amidst snowstorms in 2.3. there's some logic behind this that ties into her search for her grandfather but it's like vague and hazy in my head. I haven't given much thought to Noelle and Sucrose— Sucrose also gives "vaguely adult" vibes, idk if her character story about wanting to make a wonderland to meet her past friends in has any relevance to timeline estimation. I'd say Noelle also falls into the vague adult age range, but to me she's a puzzle, because her personality seems incongruent to how I thought she might act if she's like 23 or so.

anyways, anon if you read all this i will declare my love for you. thanks for giving me an excuse to genuinely think on this and then dump my thoughts out for the internet. you can clearly see none of my braincells really go towards Mondstadt headcanons but I hope you're happy w my response ehe
