"Everything turns to ashes; Ryujin Jakka!" He became famous across the sea for his incredible flames! Five Elders: "Damn it! Who is this guy constantly obstructing us?!" Sengoku: "This fellow definitely has a hidden agenda!" Akainu: "His flames... they actually hurt me?!" Red Hair: "This person... I must befriend them!" With each island he signs in at, he receives amazing rewards. From that point on, he's the strongest on the sea!
