what chapter will reveal her true hair or something? someone spoil me pls

so from what i've heard is that that isn't Ria. the version of Ria with pink hair is the first saintess if i remember correctly. her name is Splesia and she was cursed. this generations saintess is Diana that's why she sees Ria in her true state. and when this will happen is prob gonna be near a cliffhanger or a season's finale. cause let's be real that would leave quite the impression
