The Snake Shot
Kaido attempts to use his Snake shot to wear off Ryoma's stamina, and though Ryoma initially shows signs of sweating and fatigue, he surprises both Kaido and the spectators when his speed and power does not decrease. Near the end, it is revealed that Ryoma had been implementing a plan: he had been specifically hitting shots that Kaido had to bend his knees in order to return, thus Kaido would loose stamina far faster than Ryoma. His plan works, earning him the win.
