There’s something really special about the first episode of a new half-season, not to mention something special about the ridiculous workload it entails to do. I suppose you could say this episode marked a new start line, and made sure the viewers knew it. If you want to see that for sure, I’d suggest comparing this episode to any from the very beginning of Stars, particularly the opening. Aria is a lovely girl, although it would be difficult to expect otherwise from her name. I hope you do enjoy this episode with a smile, just as I did (particularly the first few seconds of the new OP for me).
P.S. Today/tomorrow, October 8th, marks the actual 5th anniversary of Aikatsu. Thank you for these five years!
