Beside the fact we(the ones editing the wiki) have yet to finish filling out the whole plots of either mediums to the current respective releases, there are actually big differences even though they seem small like the placement of the timeline or interactions between characters.

For the timeline, the manga starts in August during summer break before the 2nd semester while the anime starts during near the end of the 1st semester.

The anime also had the antagonist original character Ryōta Ijima being a composite as the teacher of Yumeji's class who is also the school guidance counselor, instead of the actual two good characters who were the teacher and counselor, Hasumi and Osuge, the former being a bit of a neutral character while the latter became one of the attempted vessels for "Familiar" Legion. The latter fact would become important later in the manga's story when Kyō Shiragi subtly used the fact that former and attempted vessels can see Dream Demons that manifest in reality as an inferred threat since they also feel the Dream Demons' interactions like being grabbed or being struck and the effects of their powers. In that point of the manga's story Dream Demons that manifest in reality who aren't Merry Nightmare or Kyo are invisible to those that were never a vessel and pass through them.

Anyway, as one goes on in either medium's plot the differences becomes much more apparent so the separation is more of a preemptive action since the manga will eventually surpass the anime.
