Hi there! I've heard about the Ordinal Scale movie that is being released and I am definitely going to see it, but I noticed that after book 8 (the last book covered by the anime) the plot for book 9 takes a very different turn. Which is canon? Ordinal Scale or Alicitization?

P:S I have only read the back cover of the Alicitization series, so I would prefer the comments to be spoiler free :)
