I hope the author doesn't start going overboard again, although I can see where this is going. Even the MC with Yoriichi's talent and other talents took years to reach where he is, so I hope the author doesn't put too much nonsense like Ais mastered swordsmanship easily. If marine martial arts were so easy, almost everyone in One Piece would learn it, considering its usefulness and the fact that people in that world can easily break through body limits if they follow proper training and have a bit of talent.
