From Shoujo Manga Maniac:
Ruka's a junior high student in love with her father's assistant, Fumi-sempai. She wants to become an adult quickly because everyone sees her as a little kid! But what would happen if she actually became an adult with the help of a time machine?

Miko is a shrine maiden who has never had much success at seeing or banishing spirits. Then she meets Kagura, a sexy demon who feeds off women’s feelings of passion and love. Kagura’s insatiable appetite has left many girls at school brokenhearted, so Miko casts a spell to seal his powers. Surprisingly the spell works—sort of—but now Kagura is after her!
