In-universe that stage show would probably have a title like Pure Cure Five.
Regrettably it stayed nameless and that show never appeared again after that one shot in episode 5 (not I do wonder if that was a coincidence) and we never got any more info about those girls.
Well, with it being telegraphed that they're most likely >!mother and time travelled daughter!<it makes sense that they both have one.
Of course not all of those screenshots do feature a cameo, I just kept them to increase the difficulty a little bit.
Of course there are many many more, those are just a handful of screenshots that I had already lurking around on my PC anyways
Body of a Demigryph, head from a Privateer Press Gnarlhorn Satyr, with an orc riding it (and said orc has a chaos marauder shield)
Will be used as a Khorne Skullcrusher.
"Meep Meep", or rather "Mipple Mepple" since this is Futari Wa after all
Back in the days Hearcatch did a few "joke" imagery at the beginnings of their episodes.
