Twintail 03
The only time I can think of that a Sentai team were international celebrities was in Goseiger, and even that was only a one-off thing. They don't fight all over the world either. Kyoryuger had that in its Christmas episodes... but the way this series is handling the Sentai elements, free from the constraints of live action, is closer to Samurai Flamenco than anything else. The way the heroes are being gathered one after one hasn't really happened since Dairanger, either. Red is usually the last to join, if they gather together, at all. So in some regards, the structure of the show is closer to a magical girl series, even if it's a Sentai show in all other respects.
Being able to use the other attributes is certainly a Ridiculous Power, and I'm looking forward to the combined weapon they're hinting at in the opening. The media painting Aika as a villain is... sort of understandable given the circumstances, but also a bit odd. Yuka Aisaka was never really a name I knew before, but between Aika here and Muse in Amabri, one could say she's really making a splash this season.
The dynamic between Twoearle and Aika is pretty great. I know Mayayan put out a video of her doing dirty jokes a while ago, and now it's feeling like that may as well have been an audition tape for this role. Definitely my favorite Thursday show, in a bunch of pretty great shows otherwise. (Check out Akibaranger, please.)
