Lightning Flash (Eren) has always believed that the titan ponies would break through the walls at some point, but he never would've thought it would be this soon.
And, together with his best friend Rainbow Dash (Mikasa) and Spike the Dragon (Armin) he will try and destroy every titan pony in eqeustria for killing his mother Celestia. With his father Discord gone, and things inside and outside of the walls getting worse, how can Lightning ever see his dream succeed?
