Mermaid Melody Pichi Pichi Pitch, Pretty Rhythm: Aurora Dream Recommendations
These aren't your average girls. They come from the ocean
but it isn't long before they are idol-like figures in the world.
Both have young teen girls who are trying to find their way.
Both have great/catchy music and an interesting plot-line.
Also, the girls are all idols essentially just in this show.
If you liked this anime, exspecially the music, I highly
recommend this to be something to test the waters on.
