Dragged into Drag: The males of Fotomat High and Burumu Junior High, as well as the females of Toshiba High. Granted, some of them are willing, but still!
Good Costume Switch: Both Bara sisters have their costume color schemes changed upon their Heel Face Turns; also, Kuroko gets a complete redesign, while Tora merely has her costume made a bit more conservative and frilly.
Masculine Girl, Feminine Boy: The Bandou twins; especially evident in that while Meda wears blue Tights Under Shorts, her brother wears pink Tights Under Shorts. Also, Tora, who studies ballet and is never seen not wearing jean shorts except during swim classes (where she wears a "bike swimsuit"), and Kuroko, who is into adult videos and wears a leotard as her combat attire, serve as a Pink Tomboy, Blue Girly Girl dynamic.
Meganekko: Usagi Arakawa, who retains his glasses in Cure form.
Name's the Same: Who knew that if you shared a name with the sponsor of the Video Compact Cassette, you also shared your name with a Kamen Rider Double character? (Interestingly, Philip and Philip also share a VA, but that's another story.)
Non-Uniform Uniform: Tora is definitely not going to wear a uniform if it's too feminine! She'll just play her own costume designer and slap her own jean shorts into each outfit. This is so prevalent that when going between regular and PE classes or between regular and ballet classes she just changes her top and footwear each time!
