I just want to say, the parallelism between Kuma and Sanji is massive.
Both of them are called the kindest men in the world.
Both of them are bound to life by love.
Kuma is aa threat to the the World Government. Sanji is also heading in this direction.
Both of them are some kind of cyborgs, but they have deep human feelings.
So many parallels, so many. Oda is cooking something up.
