But who are these enigmatic defenders, and how do they perform their miracles? Shin Hayata and Kiki Fuji have spent half a lifetime trying to find out--and now, their quest drives them toward a decades-old dark secret, and a collision course with a mysterious warrior from beyond the stars! The histories of two worlds, the experiences of two lives, and the destinies of two heroes must reconcile as Ultra and Man struggle to become one - and if they don't, neither will survive!"--Provided by publisher.
