Thanks. Actually her first name was Katsumi, but there's a family called Katsumi here in France who prosecuted her because of her name. So she changed it into Katsuni.
Her name is Celine Tran. She is Vietnamese/French. She is actually very well known in Europe. She has done a bunch of mainstream work. TV, movies , etc. When she did ssome porn scenes in the early aughts, she used the name Katsuni, not Katsumi.
