Short Summary
In the near past, Doflamingo and Trebol overwhelmed Law. Doflamingo told Law, however, that he would give Law anything he wanted if he performed the Perennial Youth Transplant on him. Law instead flipped Doflamingo off, and an angry Doflamingo repeatedly shot him. In the present, more people join King Riku in his journey, and Viola notices that Law has fallen. Meanwhile, Luffy makes it back to the rooftop, where he attacks Doflamingo repeatedly but fails. Luffy then notices Law lying on the ground, as the Birdcage suddenly begins to shrink.
