Katsuzo was a resident of Wano Country who died 41 years ago.
When they went to collect the ashes of the body cremated at the crematorium, the then 18-year-old Kozuki Oden used the fire to cook himself on the skeleton Odes (disambiguation). Shocked, the family of the deceased witnessed this and felt it was an insult to his memory, but when he finished eating, he bid farewell to the dead man and sent his condolences to the family. Even the mourning women were charmed by him.
