No, but also yes. You could say that I am the curse.

[ Kokoro does a spin, a ring of floating masks manifesting around her. ] I am the menreiki Hata no Kokoro, a spirit born of sixty-six theater masks. As they were used for hundreds of years, the emotions of the characters they portrayed gathered within them, they merged together into one spirit, and I was born.

So, it would be better to say that I am the masks, and the body you see is just there so that they can be worn.
