Arc 5The Rift Demon War
After the World Government fell, the new world began rebuilding while Luffy and his allies traveled freely. Their new era was interrupted by an invasion from a chaotic dimension, forcing the defenders into a prolonged campaign against the Rift Demons and their nests.
- Luffy destroyed Imu, freeing the Primordial Light, which healed Sabo, Robin, and Allen as the World Government collapsed and a new government began forming.
- Dragon convened a World Representative Congress that established new governing bodies, while Allen, Ace, and Sabo took leadership roles and Luffy chose to keep traveling with the Straw Hat Pirates.
- The Straw Hats and their allies celebrated the new era aboard the Freedom Ark and at Foosha Village as the new government handled reconstruction and everyday mishaps.
- The Straw Hats prepared to explore an uncharted region after Robin deciphered an ancient scroll, but a massive interdimensional rift opened above Carnival Island and unleashed energy-draining monsters.
- Dragon formed the Rift Crisis Response Headquarters and assigned Sabo, Ace, Allen, and Luffy to coordinate the response, develop weapons, defend the East Blue, and protect civilians.
- Allen and the others discovered that the Rift Demons grew stronger by absorbing the world’s power of existence, while defenders gained the Power of Fortune by killing them.
- Dragon launched Operation Deep Dive and Operation Nail to investigate and attack the nests, but Karasu died during the reconnaissance mission and the defenders struggled to destroy the nest cores.
- The Science Department created Purification Field generators using Primordial Light and the Flame of World Purification, and the defenders began sustained nest attacks as the Rift Demons reinforced their positions.
