For the uninitiated, Tokai Teio's voice actress, Machico, sang Tropical-Rouge! Precure's theme song obviously, that's point one.

Point two, if you look at the drawing, Teio is even singing the song, hence the lyrics drawn on it. as well as performing the same dance moves as seen in the opening sequence, alongside with Mejiro McQueen.

Yeah, that's all you need to know. I hope this informative comment clears some things up for you.

I learned this a while back, and now I always hear it as her voice when I listen to those Pretty Cure songs. For reference, Machico also did songs from the Healin' Good and Delicious Party series, as well as the Miracle Leap and All Stars F movies.

Uh-huh. That's right, matey.

Oh, guess what? Recently, Machico sang a cover of the original Kamen Rider theme song, which was re-arranged to be a exercise song for little kids.

And she also voices Kazamatsuri Megu, a character from the Kamen Rider W manga/anime adaptation; Fuuto P.I, as well as singing said character's image song, aptly titled; "Let's go ahead".
