I believe so too, she had bruises,blue and black bruises maybe, annndd I saw that shes also wearing knee support on her left knee, we know she injured her knee before, she even had to suck the liquid from her knee back in 2009 i guess, so I hope Ayu is okay and not to damage herself much from this CDL >.<
