Okay, so first off, let me get this straight.
- Jewelry Bonney's devil fruit enables her to make one younger or older, right? Don't you think it would seem unoriginal if Ain had a similar ability?
- Ain's devil fruit, as written on the wikia, is the Modu Modu No Mi, right? Why did Oda make this Ain when he could just create a storyline where Bonney would be there? (Of course I'm not questioning Oda's talent, I'm only pointing out possibilities, as we have witnessed his talent for 13 years now, without fail)
- Stating both the obvious and the WTFs.
- Don't mention it, Bonney.
