One Piece's previous chapter saw the story shift from the rooftop to inside Onigashima, where quite a few other problems still linger. From the fights that are still left, fans got to see a glimpse of Raizo vs Fukurokuju, both of which continued the usage of their paralysis ninjutsu despite being close to burning to death. At the same time, Izo encountered the CP0 but appears to be in no state to fight them off, making this quite a difficult task for him. One Piece 1039 will certainly touch on these plot points moving forward.
