Rose D. Nao (ローズD･ナオ, Rōzu Di Nao), is a 21 years old pirate captain of the Rolling Crusher Pirates a pirate crew originally from the North Blue. Since very young he had the dream to learn how to use all martial arts in the world becoming the best martial artist of all but shortly after he started practicing martial arts he had to stop due to another Nao in him not wanting to fight. During many years he was known as just "Rose" and only at the age of 20 he was able to become a full person by mixing with his other self. But due to the fact that he was now a new people he had lost all physical memories and lost the ability to fight and because of that his crew had to separate for two years, in groups of two with the exception of himself and Sho (who was responsible for keeping the ship).
