Maybe I am fanboying, but I think you misunderstood my point,

Fairy Hills first appeared in a omake, it wasn't animated, but it wasn't part of the main story, even if the designs, the story plots, the ideas were planned to fit, the result was there it fitted.

Can I ask you an example of a contradiction that occured from an omake chapter or a filler? Cause I can't come with any.

FYI: Not mentioning something doesn't make it a contradiction.
