I'm just wandering how old she is, or how old you think she is cause I don't think they say. And do you think she'll return in season 2?
I don't think that there is an official age of Yin. I would say that shes about maybe 13 or 14? I hope she returns in Season 2, she better, she's one of my favorite characters (as you can tell from my avatar to the left).
Darker Than Black Yin Cosplay
I think she's like 13 - 15. She's like... the best character, other than Hei of course xDD I really wanna cosplay Yin >>;
She is 15 in the 1st season. 17 Second Season, because between seasons the ovas supposedly took 2 years in their lives. This I saw explained in a Japanese article. (I read Japanese thought I'd save u the hazle of translation)
