An engaging plot is also crucial.

Romance is quite popular as well. Fans might pair up different characters in romantic relationships and write stories about how they fall in love. This could include relationships that were only hinted at in the show or completely new pairings created by the fanfiction writer. Some might explore the difficulties of a romantic relationship between two characters from different magical backgrounds, which can add a lot of depth and drama to the story.
Another place could be Fanfiction.net. It's been around for a long time and has a decent amount of High Guardian Spice fanfiction. However, the quality can vary, so you might need to do some sifting through.
Protection is also a big theme. They usually transform to protect something, like the Earth or their friends.

Yes, 'Tokyo Mew Mew' is a great one. The girls in this story transform into Mew Mew forms to fight against aliens. The transformation sequences are cute and the story focuses on environmental themes as well as friendship among the characters.
Perhaps Sirius Black could be Harry's magical guardian instead. In the original story, Sirius had a strong connection to Harry and a great desire to protect him. Even though Dumbledore was a major figure in Harry's life, Sirius was his godfather and had a natural claim to the role of guardian.
