Guardians: Main Characters

I started writing my own manga (it is also being put in written form on Quizilla, and possibly here as well). It is about Aiko, your average fifteen-year-old girl who thinks the world revolves around her. She has a crush on a boy named Kyle, the most popular guy in her grade. She prays for help, and she is sent Kyra, a guardian-in-training. Mimi, the trainer, comes along of course. Mimi ends up falling in love with Kyle's best friend, Chris. When she's in her human form, Chris can see her, but she gets extremely tired afterwards. Lia, a demon-in-training, has a mission to ruin
Kyra's training. After about 2 weeks of torture, Lia ends up
crushing on a guy named Chad, a member of the musical that Aiko, Kyle, and Chris are in. In the end, Lia ends up almost killing Chris, and when Aiko decides to try and save him, she realizes it was him she was in love with the whole time.
