During the Wano Arc, he inherited the legendary blade Enma , which once belonged to Kozuki Oden, and proved his strength by defeating King, the right-hand man of Kaido.
Roronoa Zoro's story is one of unwavering resolve, defined by a promise, a tragic loss, and an uncompromising dedication to strength. From his early days in the East Blue to becoming the right-hand man of the future Pirate King, his journey is built on personal honor and a refusal to ever lose again. 1. Early Life and the Promise
Tragedy struck the next day when Kuina passed away following a fall. Heartbroken, Zoro asked her father for her sword, the Wado Ichimonji , and pledged to make their shared dream a reality, taking it upon himself to become the best in the world.
As revealed in Volume 105, Zoro is a descendant of the Shimotsuki family from Wano Country. His grandmother was Shimotsuki Furiko, the sister of the late Ringo Daimyo, Shimotsuki Ushimaru.
He returned to Sabaody with a new scar, a missing eye, and vastly superior strength, fully committed to helping Luffy become the King of the Pirates. 5. Lineage and Wano Country
