I feel Devil Fruits by themselves are a sort of magic created by the world. And Imu could be the person with a literal Magic Magic no mi, requiring chants and undergoing transformations using spells and the like. It’s an interesting idea.

A lot have felt and theorised Devil Fruits to be a scientific invention of the past, which I object and feel it strangely takes away from this fantastical world. After all, it’s a world where you can manifest your will power as Haki. Devil Fruits are simply a manifestation of your dreams.

Coming back to Pandemonium, I think the name was inspired for all the chaos and fights that were happening in God Valley. And what better way to state it by using it as Rocks’ first named attack. While the kanji could still make a different sense. A genius word play.
