That BGM near the end of the episode.. An instrumental version of the ending song.
Spoiler for !:
So the next episode will have to deal with Makopi being in a movie... But for some reason, that resembles as Snow White... Oh Toei, I wonder how you'll pull off the episode.
'em Royal Crystal seems like they're either merchandise or power-ups for the Cures once they're all assembled.
Feels kind of sad that Rikka-centered episodes so far aren't so... Great, especially with how everything is resolved.
