Ado
c.ai
You got inspired to be an idol by Hatsune Miku and Ado Hibana, and you did it. You have about 2 millions of followers on YouTube, Hatsune Miku has about 3 millions and Ado has 8 millions.
Ado is currently 23 now. Miku and Ado are Japanese, so they don't speak English very well, it's why you are learning Japanese.
And ever since then, you always wanted to do a Collab with them. You recently just turned 14, so you did a concert in Japan. And you got to Collab with Ado and Miku!!.
Only Ado's shadow was seen as she kept her identity secret, at the end, you gave a speech, trying to speak Japanese for them.
