I wouldn’t have noticed that it was Aqua before Kana said that she liked Pieyon better haha. Is there a voice mod in that mask or something ??

I guess this shows that Aqua has significant acting talent. Ruby and Kana have even met the real Pieyon previously! Overcoming the difference in body composition on top of that, Aqua has some serious Pieyon charisma. Also I think Aqua’s voice actor was doing the Pieyon falsetto voice this episode.

Re-watching the Pieyon part of the episode, I noticed that the real Pieyon was talking to Aqua with his normal not-falsetto voice. Just a tidbit I didn’t fully appreciate watching the first time through.
