But Oda is really very rich, I think his descendants should sit at home and do nothing
Then they'll become IRL Celestials!
I'm sure theres part of him that is desperate for him to provide for his family as much as possible too ofc, especially his daughters and their future grandchildren too potentially. He's probably thinking very far into the future as the Japanese love to do too or even any decent parent/father ofc.
He's probably got that Walter White mentality of desperately trying to make sure his family can survive without him, that they're taken care of for the rest of their lifetimes and it doesnt matter what happens to him anymore, as long as they're secure/safe too.
I may be giving him too much credit though, who knows lol.
