I wasn't so sure at first, because the art started out with all the guys having weird too-long faces and I was expecting just another shoujo manga with a shy ditzy heroine who wanted to be a star and worked really hard at it and didn't have too much depth. Well I was wrong. The art got beautiful and instead of an annoying main character who falls in love easily and cries too often (not that that's a bad thing, it's just been done too many times) I find she's actually kind of... scary. And unexpectedly devious, while at the same time, being sweet and innocent and full of heart enough to still be lovable. Don't know how that's possible, but you kind of lover her more because of her evil vengeful side that doesn't back down from a gritty fight to the death. Besides, her inner demons are adorable. She's got to be the most interesting, changeable main heroine I've read. She's aspiring to be an actress (strictly for a very roundabout sort of revenge at first) so she gets to put on a dozen different personalities and looks and all of them really suit her in different ways. It's fun (and hilarious) to watch her grow and learn and sparkle and freak out and melt and send out blasts of dark energy and pin terrified people down with her invisible little demons, which seem to be more real than just figments of her imagination. She's enamored with both sparkly fairy tales and the realistic self-made voodoo dolls that she crushes under her feet or talks to for advice. In short, she's a little crazy, a little naive, and very determined. And you have to laugh and love her for it.
As for the rest of the characters, they've also got a lot of different angles to them. The evil ones of course often turn out to be just people with problems and selfish desires who might really be okay if they're dealt with the right way, and Kyokou seems to have a talent for that as well as acting. They've got histories (especially Ren, who gets more and more interesting the more you don't learn about him) and feelings but it's not so wishy washy that you get bored and tired of sob stories. They're all different and react differently to Kyokou for different reasons, and at the end of their stories there's usually that warm fuzzy feeling of happiness.
As for the romance, that may be more typical, but still sweet and slightly frustrating (woot for love triangles and such) and I'm ever eager for developement.
Over all, an awesome series!
