One Piece S10E71 - The Number-One Samurai in the Land of Wano! Here comes Kozuki Oden!

The night before the great battle, Orochi orders the destruction of the Sunny along with some bridges across the country to block Akazaya samurai's allies from their rendezvous. Disappointed, the group of samurai still sets out for Onigashima with the memory of their beloved lord, Oden, in their hearts. However, 41 years ago, Oden was not respected by everyone.
