How does Ayu's team find extras for their music videos?

[AyuLover]

Again, I'm pondering this other question. How does Ayu and her team find extras to be in he music videos?

What I mean by extras is like the boy & girl in "Vogue, Far Away, and Seasons", the mother & daughter in "Dearest", the dancing people in "Greatful Days", and the boy, his parents, officers, and man on the tower in "Endless Sorrow". Those are examples of what I mean by extras.

Do they look in talent agencies or what? I'm really curious.

Can someone please explain this?

Arigato-gozaimasu!
