Law is the deuteragonist in the post-ts, biggest contributor in the yonko saga. Takes a backseat now but will play a major role in the final battle. Will of D fighter, and immortality surgery plot lines. There’s a reason why Oda ensured that Law’s fate wasn’t vague after fighting BB and even highlighted him in this panel.
Notice anything? Yup, those are the only strong D clan fighters introduced in the story that will still be active (except for Ace). There’s no Vivi, Clover or other shit thrown in there.
