Although, considering the heavy subtext of the Precure series, you could say the last one MIGHT be a lil' spot on for Nabatame... In fact, the presence of Nabatame turns this particular Precure into 'the most Les Yay-ridden Precure series ever' and the first Precure that got a LesYay page on its own!
Hilarious in Hindsight: Eiichiro Oda of One Piece considers the Precure series a rival series he had to defeat because his daughter likes it better than his manga. Then... the main star of One Piece goes to voice Ira.
On the other hand, while Minako Kotobuki (Rikka/Cure Diamond) wasn't part of any previous Pretty Cure season, the fact that she was Tsumugi Kotobuki probably makes up for it.
Non-Singing Voice: Only for the end song, which has Cure Sword singing but is not done by her voice actress, Miyamoto Kanako, who has song for the series in the past, but instead is done by Hitomi Yoshida.
