User blog comment:FairySina/Reasons Why Sky Pretty Cure can't be made by Toei.../@comment-25315805-20170405195253

In making this list, you pretty much nailed down all of the things that I wish Toei had the guts to do >o> I've been yearning for a season with deep lore and more than six cures for YEARS now, and I think it's one of the reasons that I have more favourite fanseries than I do canon series, because it seems we do this on a regular basis.

(If I'm being completely honest, imo Sky tops every canon season because of all the reasons you mentioned, and I think Sky would be my favourite Pretty Cure season were it real. ^^)
