Strong World was written by Oda and can be tied in to the manga. Why would that be any less canon ?All the movies are filler, we saw last Shiki with Whitebeard i think...
Why is it filler ? Oda wrote the story.The movie is filler. Shiki is probably still alive.
Well we got a whole picture about him and SH so now shiki chapter is closed.Is he alive and whats going on with him? I though he died and did him and luffy get into a fight was it all filler
