I have a question I've been wondering for a while, what is the shipwrecked chapter? I saw the chapter 39.5 prologue where it says some of what happened but i can't find the rest. I really want to see those chapters so could someone please tell me what the full special chapter/miny arc/ thingy name is. Then I can look it up or go buy the book.
