Arc 14Thunder Emperor’s Challenge
After Enies Lobby’s destruction, the Marines publicized Uchiha Xin’s strength and made him a target for the Four Emperors. Xin expanded Sky Island’s reach and army, then brought Tashigi to Hawk Eyes’ duel, where she fought for Black Blade Yoru.
- Uchiha Xin left Kalifa and the ruined Enies Lobby behind as Kumadori rescued Lucci, and the Marines learned that Shiki had fallen and Enies Lobby had been destroyed.
- Sengoku raised Xin’s bounty to three billion Belly and named him Thunder Emperor, prompting Whitebeard, Kaido, Charlotte Linlin, and Shanks to respond to his rise.
- Xin revealed a modified Float-Float Fruit that could grant flight without conflicting with other Devil Fruits, and Robin took it to help Sky Island’s warriors reach the Blue Sea.
- Robin and Tashigi led a hundred warriors toward Fish-Man Island to investigate missing people and slave traders, while Xin made Kalifa responsible for Sky Island and the Divine Palace.
- Xin empowered 362 Sky Island warriors with Tailed Beast power and ordered Kalifa to train them until they passed assessment.
- Xin traveled to the island where Hawk Eyes had challenged him again, bringing Robin, Perona, and Tashigi along despite the Red Hair Pirates’ presence.
- Xin gave Black Blade Yoru to Tashigi and promised she could keep it if she defeated Hawk Eyes, who accepted the duel and vowed to reclaim the sword.
- Tashigi initially drove Hawk Eyes back, then adapted to his precise counters and continued growing stronger as their duel progressed.
