Monkey D. Luffy
In the story, Pirate Hunter Zoro is the first to join Monkey D. Luffy after he is saved from being executed at the Marine Base. He is the crew's combatant, and one of the two swordsmen of the Straw Hat Pirates, the other being Brook. As a native to the East Blue, he came from the town known as Shimotsuki, where he trained in a dojo and learned the one and two-sword styles (ittōryū and nitōryū).
