Prétear is loosely based on Snow White and the Seven Dwarfs. The arc of the fairy tale informs parts of the story's structure, from a problematic stepmother to the number of guys looking after the main character. But the "dwarfs" aren't; they're Leafe Knights, magical protectors of the world's life force, who find in Himeno, the main character, the catalyst they need to use their powers most effectively. Neither are they all in love, let alone all in love with Himeno. Some of them are only children, none of them seem to be the same age as each other.
While this is partially the story of Himeno and the Leafe Knights, it is equally the story of Himeno and her family, her father, and new stepmother and stepsisters, learning to deal with new family dynamics and why people may be hostile to each other. Himeno is suddenly living in an enormous house with servants, with stepsisters raised in a way very different from that of the daughter of a washed-up romance writer.
This is not a series which daring pushes new ground, or shatters fairy tale or magical girl genre conventions. For example, theengineer and I could predict far more of what happened in the final episode than all the twists and turns which led up to it. But that didn't make it any less satisfying for me.
Thank you, cliosfolly, for introducing me to it!
P.S. If Sasame has a leaf-ornamented ear cuff and Hayate a leaf-ornamented ring, surely all seven of the Leafe knights have leaf-themed jewelry. I only noticed this at the end, so didn't have time to figure out what all the others were. Hajime's has to be his hair ornament, and Mannen has a big silver wrist cuff which must be his, but what about Kei, Goh, and Shin? (I only websearched for this superficially; surely the answer is out there somewhere.)
