Can a young adult woman who is 20 call themselves 乙女 or otome?

I saw this image here:



and this character is at least 20 years old, and they refer to themselves as otome and all? So I wondered if this is correct or if one can be called that.

So does it say anything about the characters age?

では、登場人物の年齢について何か述べているのでしょうか？

If it is she 20 years old, it is "乙女(Otome)".
But it is not "乙女(Otome)" if it is not a virgin.
