She is bisexual in the books, due to being on the run she was used by both sides, and the women were less harsh. There is a couple chapters in one of the books about it, but it really wasn't a focus in the books. The focus was more on trying to not be caught by the wild hunt and the elves in charge of it who wanted to use her blood line.

I just asked Chat GPT and this is what i got:

However, Sapkowski doesn’t label Ciri’s orientation, and after her time with Mistle, there are no confirmed relationships with either men or women.

So the most accurate summary is:

In the books, Ciri is shown to have had a romantic and sexual relationship with a woman (Mistle), but her overall sexuality is not explicitly defined.

She is as intented in the source, same in the games

This why I couldn’t beat the Witcher 3.

It was portrayed much darker in the books. She was sexually abused twice. First by the guy and then by Mistle. In the show nothing really happened with the guy and Mistle actually asked Ciri if she should stay with her.

this is not an addition to the show, in the books (and games) she expresses interest in both men and women. she sometimes flirts with men, but in general is not very openly interested in sex or sexuality.

because of this.

You should treat the show as its own thing. A lot of it is changed from the books. The games too.

I miss the days when we would just joke about it being an awesome opportunity for a show when 2 lesbians kisses.

Nowadays when it happen, in fiction of all things, you have a subset of the population that lose their mind.

they lost their minds about it back then too, but kept it to their blogs. sadly, now we all have to hear about it every single time.

As others have pointed out, it isn't explicitly stated whether or not Ciri is a lesbian and as far as I know Andrzej Sapkowski never did either.

The writings however confirm that she's shown interest in both men and women, suggesting bisexuality. Although I don't remember a single instance where Ciri actually slept with a man. Just Mistle, it seems.

As salamander mentioned, she has flirtatious interactions but that part of her was largely exaggerated in Witcher 3 and the scene explaining her cleavage is CDPR "interpretation". Meaning, she's not really as promiscuous as she sounds. Considering she's rather selective and romantic relationship occur under specific circumstances, while sexual relations are quite rare, Ciri could be demiromantic or something like that.

she gives heavy bi vibes uwu

She definitely wanted to sleep with Hotsporn

I would disagree

引用自 Good Night Owl：

but I think she actually grew to like the woman.

The books end with her and Galahad. Mistle was the first and only woman in her life and I'm really not fond of their "relationship" because of how it started.

I would say Ciri grew to like men.. Not the other way around.
