User blog comment:CureHibiki/Theory: Why Mirage never showed up in Episode 46/@comment-25648652-20150106085532

Wow! That makes sense.

I think Cure Mirage will come when HaCha Cures are really in a pinch. Cliche stories, one or two seconds before HaCha Cures defeated or die, Cure Mirage come and save them, and they transformed into their ultimate-upgrade-form (actually i'm waiting to see this form :D). But i expect something more interesting than that from Toei.

And i want Cure Lovely is not the only cure who has an ultimate-upgrade-form like Cure Heart who is the only cure that got Parthenon Mode.
