Volumes 11-13+ currently tell a consistent story. I.e. there is not much room for any side stories.

The Alicization arc currently has 2 known side stories, "The is but one ultimate way" (non-canon; sometime after volume 14 or so) and "Cradle of the Moon" (happens after volume 14 or so; can't say if it is canon or not).
