@udomsa33 @pdonk I would be absolutely astonished if he wasn't really strong in some fashion. Keep in mind that the entirety of this series has portrayed Ousen as a highly intelligent man who plays his cards very close to his chest and never reveals more than he absolutely has to; the kind of guy who waits until the absolute last second to take a swing. I don't think he had a GLORIOUS SCHEME to get out of that situation, but he probably had something up his sleeve.
@Regilius You would effectively need the leg strength to hold on to the horse for at least a few seconds in the horizontal position, and the muscular strength / isolation to lunge entirely from the waist, independently of the lower body. In short, the kind of technique and physique that would make most Olympic acrobats do a double take.
