That's a plot from the Web Novel, comparatively it would be covered in LN v14 or v15 (when they get released).

Also, Fuuga doesn't actually attack Garlan, but instead helps a rebel group in there to take control of an island under Garlan (and in a way form a puppet rule), which was over-ruled by Monsters (which Fuuga helped clear out).
