The genius physicist, Sento Kiryu, and his muscle brained partner, Banjou Ryuga, wake up in Equestria after the combining of the worlds! Now trapped in a world that isn't their own, they must stop the evil leader of the Blood Tribe, Killbas, from destroying Equestria and all of its inhabitants. Even worse, a new Faust organization has been set up and evil ponies utilizing the man-made Fullbottles are making their selves known. Two stories are about to intertwine, and only the new bonds created can stop what's about to happen!
