Do keep in mind this is a magical girl's anime, it's demographic is towards young girls. Nonetheless, I still watched it.
So the story is about a girl who travels around trying to find this Rainbow Flower thingie. She has this magical item that allows her to transform into different outfits by using flowers, a bit hard to explain. The power changes after a bit. The main thing that I loved about it was the never ending adventure, she goes to different places and meets different people. Very wholesome stories.
Deal with the animation, it was animated in 1979, they tried their best. The backgrounds look quite pretty the animation is fine for the time. The sound was also fine.
The main characters are a 15 year old girl, her pets, the main villain, and the villain's sidekick. I do think the villain was a bit bland, just someone trying to steal the Rainbow Flower from the main character. The characters we meet along the way are very interesting, they have their own troubles and goals. Each one of them offer a great story.
Overall, a great anime to watch for wholesomeness. It sorta reminds me of Violet Evergarden, if you like that, then you'll enjoy this one too.
