#9 – KOSHIRO
Koshiro is Roronoa Zoro’s teacher and Kuina’s father. Zoro is grateful to Koshiro for teaching him the sword and giving him the Meito Wadō Ichimonji. Although he didn’t understand it at the time, Koshiro taught Zoro that there is much more to being a swordsman than the ability to cut through anything. A sword that can simply harm anything isn’t a real sword, and there is no sword mightier than the one that protects what it wants to protect.
