Ai is a half-demon and shunned by both races. She lives every day with curses of different types and has a hard time dealing with anyone. Then, the monk Sol, the High Priestess Kagone and the demon Note show up. Her life suddenly gets a whole lot funnier, chaotic and just different, adding friendship, courage, power and a little love to the mix. Especially since she is ironically the only one who can bring peace to the two species she hates most in the world: humans and demons.
