Arc 16From Rogrim to the Sky Archipelago
The Straw Hat Pirates completed Rogrim’s trials, then survived Buena Festa’s deadly Expo and explored a sunken civilization in the Echo Abyss. They reached the Sky Archipelago and helped Kumokakure Village repel corrupted cloud beasts, but the Dark Abyss had also corrupted the Cloud Roar Behemoth.
- The Straw Hat Pirates trained across Rogrim’s trials, reached the summit of Unyielding Peak, and passed Gar Testa’s final challenge with Allen’s help.
- The crew departed Rogrim for Delta Island, where Buena Festa’s Expo turned into a deadly ritual that Allen stopped by closing the rift to Nage Yurate.
- The Straw Hat Pirates escaped Delta Island, then followed a distressing echo into the Echo Abyss and discovered a sunken ancient city.
- Allen preserved the Memory Ark’s knowledge as the ancient device crumbled, and the crew sailed toward the Sky Archipelago.
- The Thousand Sunny crossed the Storm Corridor and reached the White Sea, where the Straw Hat Pirates met the Winged Tribe at Kumokakure Village.
- The Straw Hat Pirates fought corrupted cloud beasts, and Allen purified them before the Winged Tribe revealed that the Dark Abyss had corrupted the Cloud Roar Behemoth.
