Mina is a girl who is going through her high school years without many adventures. Suddenly, she is plagued by a mysterious dream just before she decides to travel with her friends on a seemingly uneventful trip. Her life takes a twist as she finds out that her friend is the last living descendant of an ancient organization known as the magic repellers--sworn to rid the world of all traces of dark magic. With their absence, another group has risen to power with the goal of creating a perfect elite society of immortals, with all of humanity beneath their heels. Accidentally discovering a lost experiment that is the last step in total domination, Mina and her friends are thrown on a path to stop the rogue magic users and hopefully get out alive. On the way, Mina meets new allies, battles monsters and other unearthly creatures of the night, faces mistrust and heartbreak. All with the fate of the world riding on her success.
