Hibiki Amami isn't what you'd call a normal high-school girl. She's rather eccentric due to her sixth sense that allows her to see and communicate with ghosts. Her days are never exactly normal which works out fine since, neither are her classmates. Most of whom completely accept Hibiki's gift, but her classmate Narumi Inoue refuses to believe no matter how much proof she sees. As Hibiki lives out her school days she finds herself making new irreplaceable friends, living or dead.
