The anime series Tokimeki Tonight anime series came out in Japan in 1982 around the same time as Urusei Yatsura, The Kabocha Wine, Space Adventure Cobra and Super Dimension fortress Macross when it comes to 80s anime
I randomly got Super Love Lotion in my recommended one day and I liked the song so much I decided to watch the show. Glad I did. Amazing series, I wish they'd made the whole manga though, really left me wanting for more. I wonder why, was it not popular enough?
Hime-Chan No Ribbon is very similar to Tokimeki Tonight as it also tells the story of a girl who transforms into someone else. There is a magical world too and the love triangle between the protagonist the love rival and the love interest is very similar and the rival, named Hibino has the almost the same appearance and personality with Yoko. The girls have also the same struggles with their powers and situation, but two differences is that Ranze is from the demon world and is not a human, whereas Himeko is a human who obtains her powers from a girl from a magical world and that Himeko liked someone else first who didn’t liked her back and then then she develops slowly feelings for Daichi, the one who immediately discovers her powers and keeps them a secret.
