Another day at school for Rias, Issei, Xenovia, Asia, and Koneko until one day a mysterious warrior falls from the sky. What will happen? will he be enemy or ally?

I do not own dragon ball, dragon ball z, dragon ball Gt, and dragon ball super please see the official release

What of the fourth great shinobi war ended a bit differently than what we expected? Perhaps a certain ninja will make the best of what's to come,
