Seems like it'll be Shiki so the Strong World creature comparison made weeks ago was a smart one. I'm glad if that's the case since he didn't seem like the type to fall into irrelevancy forever.
I just wish more happened in these chapters. It's not bad, just not much going on beyond some cool reveals like for Loki. I hope stuff starts hearing up soon. I don't mind a focus on the island, but progress can be made while doing that.
Because Chapter 0 is also canon, people always wondered about Shikis whereabouts, and about his "20-year plan," which never came to fruition in the manga but was used as the transition for the non-canon movie plot instead. Oda still could make this work somehow. If it is him.
So technically, this "plan" could still happen. Even though it is a little bit past the 20-Year Mark now, but that's just a minor detail that can be overlooked, I guess.
Scopper Gaban fans vs Shiki fans until the reveal.
Watch it being non of them at the End, classic Oda Move.
