Chapter Summaries

Ron received a silent call from Law and traced it to Rosinante’s spatial marker, learning that Rosinante had given Law the Op-Op Fruit and was facing Doflamingo’s officers on Minion Island. Ron opened a Spatial Door from Shimotsuki Village and went to rescue his brother.

As Ron and Law sailed on, Big News Morgans prepared a sensational report claiming Ron had nearly beheaded Whitebeard.

After learning it had cores in both the real world and the Sing-Sing World, Ron opened a door into the other realm and went to attack its core as Shanks held off the real-world body.
