Forty-one years ago, Oden had not yet earned the respect of everyone, but when the angry mountain god almost killed Kin’emon, Oden stepped in. Still, disavowed by his father, Oden journeyed around the country, gathering followers as he went.
Oden transformed Kuri and was made Daimyo over it. He also met a kappa fishman and two minks, who soon became his followers. Kin’emon and the other vassals took Yasuie's strong words to heart and began transforming themselves for their lord.
As Oden began his voyage, he was in awe of all the things that he had never seen before, and for the first time in his life, he became a wanted person and made the headlines, catching the eye of a high-profile figure.

Things are heating up on the second floor as an enraged Ulti prepares to attack Big Mom. Elsewhere on that same floor, Sanji runs, jumps and kicks his way through seemingly endless waves of gifters and pleasures, a heavily bandaged (and very sleepy) Zoro in tow.
