Since the revelation of Smile's original dub name "Gangnam Girls", many fans figured that this series would be the one dubbed, based on the description of the series.
Many fans called out Episodes 10, 17 and 19 being removed due to their subjects, 19 especially.
Missing Episode: Episodes 10, 17 and 19 of Smile were removed from the Glitter Force dub. While 19 was obviously removed because of the topic of Yayoi's Disappeared Dad, it's not quite known why 10 and 17 were, though 10 may have been removed due to focusing on Akane's resturant, which features Japanese cuisine (though they could have just labelled it as a Japanese resturant), and 17 was presumably due to the humour of the episode not translating well to international youth audiences.
And due to the kanji on her last name being different (日 as opposed to 火), Akane/Cure Sunny is definitely not related to Rei Hino or Eiji Hino. Same for Nao/Cure March and Retasu Midorikawa even though in their case the kanji are the same — though the franchise does have a Retasu expy...
Actor Yūji Mitsuya tends to play comic relief characters, or the young and cute hero. Here, he's the thoroughly evil Joker.
Sequel First: With exceptions of Australia, Canada, Germany, Italy, parts of Latin America, Spain, and UK; Smile as it's ninth series hit daylights in a few countries like US, Brazil, and France as it's Saban adaption via Netflix.
