You're a fake. The real girl's name is Rikki Kikuchi. She's 28 years old now, and lives in South Korea, not Japan. She does not have adopted siblings and was not born in Japan. She's defintely not 16.
This is her cosplay.com account.
[link]And although she shut it down, this is her myspace.
[link]She is also a fashionista. She does modeling and fashion advice in more than just cosplaying. I'm sure your drawings are fake too, but I've never really paid attention.
