Question/opinion regarding her: Do you think she's a Miku copy? A bunch of people in the fandom are calling her "Chinese Miku" and bashing her desgin.
They look a similar in my opinion, but an opinion on a Vocaloid shouldn't be her desgin, but her voice. (Which is something I feel like the fandom forgets.)
