Raizou tries to use a fire technique against Ryukugyuu, but it's totally useless. The Admiral pierces Raizou with one of its branches and begins to absorb his nutrients. Meanwhile, Sukiyaki leads Robin and Law to a secret location deep inside Oden Castle. In an ancient Wanokuni submerged by water pooled by the island's walls, there is a new room where the Road Poneglyph is located. Sukiyaki then confesses to them that destroying those walls and opening the country would mean releasing the Ancestral Weapon "Pluton". Back to the combat, Momonosuke finally manages to cast a "Bolo Breath", but Ryukugyuu is able to regenerate. The Admiral prepares to attack, but just then he senses Shanks' Ambition and decides to retreat. From not far away, Luffy and part of the crew watched the fight with the intention of intervening if necessary. That explosion of Ambition made Luffy to remember a familiar face.
