As soon as I wrote "Rewatch: Doubtful", I went back and rewatched some of the more exciting parts, for the feels, as they say. One such part was Yuko and Co. at the election gala. It looked like the creators went whole hog to express the girls' personalities, so I went to Youtube and watched some of the old election coverage to compare.

Yuko herself did not look as boisterous, but she was smiling even in an old election where she pulled 6th (she is still active and ranked 2nd in the 32nd round). Oddly enough she's one of the most stable individuals among the winners, belive it or not.

I don't know about pheromones, Kojiharu is pretty indeed. And yes, she was disappointed with the low rank (IIRC her highest was 6th, she is 9th in the 32nd).

Takamina is, well.. very robust. And it may not be immediately apparent, but she used to wear the very haircut that the anime portrays (if not lampoons), or at least something very similar.
I'm sure the characters would seem very recognizeable to any fan of 3DPD versions, should they check out the anime. But on the flip side, I have to wonder how well the anime is going to age. Kojiharu and Tomochin are slipping in rankings. Acchan and Mariko-sama graduated (she was 27). In a few short years nobody will even remember who all these people were.
