LOL! I want a "Big Breast Champion" shirt. I also like Ayu's expression in that picture. =3
More than likely she hasn't a clue. When I was in Japan I saw a little girl wearing a red shirt that said "SEX" on it printed right across her shirt. And on another occaision, there was a 12-year-old who had a white bag that said "F---" all over it.
It was eye opening, to say the least.
