Spoilers Off nanodesu!
- This season's themes surrounding the future may serve to explain why there is an emphasis on technology that wasn't present in previous seasons. Given the parallels between the show and the real world as seen with the implications of the Dark Tomorrow Corporation, it can be assumed that the rise of prominence in technology is reflective of our world's innovations of future technology.
- The Cures are seen communicating with each other using their transformation devices like a phone. In addition, Saaya has been noted to be keeping up with the latest technologies on her personal laptop and gushing over new models of power tools is of any indication.
- The Mirai Pad is basically a tablet not unlike an iPad, complete with access to a website called "Curestagram" that represents the rise of social media as a news outlet in the real world.
- Charalit's new gig after being purified is posting videos of himself on the Internet. In other words, he's basically become a vlogger.
- Perhaps the biggest example of this is Ruru. She's an android manufactured by the Dark Tomorrow Corporation to assist its members with getting menial tasks done, not unlike what most robots are designed to do today. Her development arc centering around her gaining emotions and starting to think for herself also reflects the topic of Artificial Intelligence and the stories of how some robots can grow beyond their programming and rebel against their masters.
- With this in mind, it also explains her low status in the company hierarchy despite her prowess. With Charalit and Papple's designs being based off of previously established eras from the past, it's safe to assume that the other members of the company follow this trend. Ruru, being an android, represents the future, which has yet to happen and isn't as established as previous eras; she has yet to solidify herself as a mainstay in the timeline.
- When Ruru summons an Oshimaida, there's a brief moment where she steps on four tiles not unlike a DanceDanceRevolution control panel. Except it's not a reference to DDR. Look closely at the layout
◊ of the squares. They're keyboard arrow keys. Perfect for the character who has a computer for a brain. - Ruru's model number containing the letters "RUR" is a clever nod to the play R.U.R., which not only introduced the word "robot" to the English language, it features artificially-made organisms who are treated like machines even though they function like living things, not unlike Ruru herself. Additionally, the robots at the end of the play eventually rebel against their makers. Guess what Ruru ends up doing?
- Emiru is briefly seen wearing a VR headset in Episode 19 to get a better feel of what a fashion show is like.
- And that's not even getting into Dr. Traum, who has the gimmick of being a Mad Scientist who relies on machinery to create his Oshimadas.
- Ruru has to eat more after defecting from Criasu. During her employment at Criasu the company can stomach the electric bills and the electric load from her daily charging of her batteries. After her resignation she no longer have access to that power source, and she can not recharge using the power outlet of Nono’s, for fear of either blowing fuses or blowing the electric bills. This forced her to switch to digesting food as her primary source of energy.
- The show having darker undertones and various Parental Bonus jokes that appeal to an older audience makes sense when one realizes that the people who are working adults now were probably kids when the original Futari wa Pretty Cure first aired. Thus, in celebration of the 15th anniversary of the franchise, it's only fitting to have both the new and old generations come together to watch a show that's able to cater to both of them, something that's made more evident by the fact that the yearly Pretty Cure movie is going to be a crossover between the newest group and the original duo. It's symbolic of the union of both young and old fans of the franchise.
- Cure Yell's name. It seems odd as it is the only English name in a team of French names, but it makes sense when we think about Hana Nono as a person. Unlike Saaya and Homare, Hana doesn't have any specialized skills like superior athleticism or knowledge. While she thinks this makes her a Master of None, it actually makes her a Jack of All Stats. Unlike the other two, Hana's future is much more ambiguous and less restricted, but this also means that she could become anything she wanted to if she puts her mind to it. And as for how this translates over to an English name, English is one of the most commonly spoken languages in the world. It isn't as specialized in specific areas compared to French, but it makes up for it by covering a wide assortment of areas and by being very recognizable. In other words, it's just like Hana.
- Episode 42 adds a new layer to the name: As Henri points out it sounds similar to aile, it shows that Hana's standout nature, while initially seeming separate, fits right in with the rest of the Cures.
- I found out something else that could apply to Cure Yell's name! Obviously, it does seem weird at first seeing that Hana's alias is Cure Yell instead of Cure Cheer, since she's, well, a cheerleader. But one time I was reading a book that was published and also took place in the 1950s, and said book had a different name for cheerleaders back then. What were they referred to as? Girl yell leaders.
- At first, Homare's flight attendant theme as Cure Etoile seems random and completely unrelated to the figure skating ambitions she's been expressing throughout her Character Development arc. Then you realize that she's expressed several times the wish to 'fly'. While meant figuratively, her dream of 'flying' and future still materialized in her Mirai Crystal - and subsequently in her Precure outfit.
- When they are in the Little Mermaid, Bishin mocks Homare for her Unrequited Love, even telling her to dissolve into sea foam like the mermaid in the original story. However, the original little mermaid only did so because she chose not to kill the one she loved in order to take back her old life—something Bishin either never knew or never cared about. By accepting that Harry loves someone else and choosing to keep her feelings secret for the moment, Homare is more like the little mermaid than Bishin thought.
- Ruru and Emiru are essentially one huge throwback to the original Precure duos. This makes sense when you find out that Emiru was the one meant to be the Sixth Ranger not Ruru and Mother essentially split the powers in half so the two would go and save Hana already. Amour and Ma Cherie are essentially sharing the same powers and their PreHearts are one half of the original device.
- On the topic of Ruru and Emiru, when they declare "Embrace your shining future!" they hug each other... Implying they're each other's future. D'aww. Also doubles as a heartwarming moment.
- The reason why Cure Tomorrow was the only Cure not to be destroyed. George is implied to be her father.
- Hana's midriff exposing after transforming into Cure Yell represents pregnancy, fitting the character who becomes a mother at the end of the season.
- The Bad Future. While we never see exactly what it was like, it's implied that the timeline was going downhill fast. For starters, Hana never had her Important Haircut; which means that she never tried to "become the Nono Hana" that she wanted to be. Emiru was the only Sixth Ranger since Ruru didn't exist yet, meaning that she didn't have a supportive friend to defend her from her brother and grandfather. The group was most likely impaired because they were down a member and Hana wasn't the beacon of support that we know her as. They also didn't have guidance from Harry or Hugtan to motivate them. And even though Criasu Corp didn't exist, toge power was still increasing at an alarming rate. Along the way, Hana met George and had Hagumi. But eventually, Hana was Driven to Suicide because of her Precure responsibilities. But while Hagumi continued to fight for the future as Cure Tomorrow, Hana's death triggered a Despair Event Horizon in George. This caused the chain of events that led to the beginning of the series: Criasu Corp was born, Cure Tomorrow was locked away while the other Precure were killed, and George began his plan to freeze time permanently so that Hana would never suffer again. Thank goodness Hana chopped her bangs off.
