OK, Yaemori I can see doing this intentionally to try and force some Progress, but how the hell did she get Ruka out of action? There's approximately -300% chance that she'd allow the two of them to be alone.
Really hope this is just seguing over to the harem end, since otherwise this is probably all we're getting for the non-Yuuna contenders and Hibari is best girl.
I'm wondering if the sea fairies are being influenced to hate Tiararose by the new heroine. I don't want to jump to judgements about her right off though (plus it WOULD be kind of lazy to have the exact same plot twist as the last heroine), so we'll see if she ends up being nice or villainous...
