Meet Yoshiko's demon... Aamon.
Yoshiko: He's inside of me but I control him.
Aamon: You don't control anything. At any time, I can make you do something that you'll regret.
Yoshiko: Ignore him. He's only a stupid thing that gets in the way.
Aamon: And yet you made a studio for everybody to get to know me?
Yoshiko: That's because I'm tired of keeping it a secret.
