The old musicals did that and the Light of Hope thing to reflect the anime. These musicals may make the odd reference to the 90s anime, but they're otherwise faithful to the manga, so I doubt we'll see Beryl and we'll probably get Sailor Cosmos. I hope we get Mnemosyne and Lethe (since they're obviously my faves), but I hope we get Papillon, too. I feel like they could give her a great song about soul harvesting or something. She's way more interesting than Phi, Chi, or the other Animamates.
True, but the Amazon Trio in Amour Eternal
were pretty much taken directly from the older musicals which in turn were inspired by the '90s anime. I'm confident we'll get Sailor Cosmos, but I'm also a nervous about the direction the newer musicals are taking. I'm sure I'm just being paranoid though.
