Short Summary
Robin translates the red poneglyph, which Inuarashi reveals to be called the Road Poneglyph. This poneglyph leads to a map of an island surrounding Raftel, and there are three others, which if read will allow Raftel's location to be discovered. One Road Poneglyph is owned by Kaido, one is owned by Big Mom, and the other is lost. Inuarashi and Nekomamushi then reveal that the Kozuki Family were stonemasons that invented the poneglyph 800 years ago, but the knowledge of how to read them was not passed to Momonosuke's generation. It was lost after Kozuki Oden was killed by Kaido, whose crew currently occupies Wano Country. Kaido is currently pursuing them because Oden went to Raftel with Gol D. Roger and witnessed the secret of the world.
