Survival Rate: 10%! Priest Satori with the Power of Mantra!

Pressing deeper into the forest, Zoro, Nami, and Robin are puzzled to find soil underfoot in a place meant to be made entirely of cloud. Robin remarks that the sky island offers a wealth of things worth studying. At the Ordeals, the four priests wait while the trio weighs which gate to pass through. Luffy pushes for the Ordeal of Balls, and Usopp, finding it the least menacing-sounding after running through the downsides of each, agrees to trust Luffy's gut, and they commit to it.

Beyond the gate they encounter Satori, one of the four priests, who easily dominates them with Mantra, the power to anticipate an opponent's movements, and Impact, a blow that strikes a target from the inside out. With the dial ship nearly drifting out of view after Satori's opening assault, Luffy orders Sanji and Usopp to secure it while he handles the priest himself. Every attack Luffy attempts is read in advance, and Satori counters with a barrage of Impact strikes that drives Luffy's head into a tree, prompting the priest to admit his target is a tough one.

This episode adapts material from chapters 246 and 247 and debuts Satori's Mantra technique. It marks the first time the series visualizes Usopp's imagination, picturing what each ordeal might be like from its gate name. The wiki notes the device returns later during the Dressrosa Arc, when he imagines Luffy being turned into a toy.
