Ross, Aki

Dr. Ross is a scientist in the post-apocalyptic mid-21st century who has been infected by a race of aliens called Phantoms, which landed on Earth and are destroying all life on the planet. Although she is dying due to her encounter with the aliens, she now possesses the ability to connect with their secret of survival through strange, recurring dreams, and she can use this to help the remnants of humanity fight the xenomorphic parasites that appear to be draining the souls of the surviving population.
She has allied herself with the "Deep Eyes Squad", a specialized unit of soldiers determined to eradicate the alien threat once and for all. Aki is tasked with finding the eight special spirits that are said to help save the planet. (from The Final Fantasy Wiki)
